In my world, cold weather means quick low carb meals and comfort food recipes. Especially low carb casseroles, like loaded cauliflower casserole, big mac casserole, and my personal favorite, this cheesy chicken bacon ranch casserole recipe. The beauty of it is that it doesn’t taste like health food at all (Cheese! Bacon! Ranch!)… the whole family will devour this easy dinner. But secretly? Yep, it’s actually a low carb keto chicken casserole.
Low carb chicken casserole recipes are one of the best easy keto dinners. You can throw them together in advance or make them last minute. The prep time is typically minimal, especially if you have some basic staples in your fridge already. Besides, the ability to customize a basic low carb chicken casserole recipe for various ingredients you might have is a huge advantage. That’s why I have two ways to make this one (and lots of substitution options) below.
The ranch dressing makes this bacon ranch chicken casserole that much more… comforting. There’s something so perfect about a creamy, tangy ranch dressing combined with chicken, smoky bacon and gooey cheese. And there’s no arguing that chicken, bacon and ranch make an amazing, comforting dinner combo!
What Is Chicken Bacon Ranch Casserole?
Chicken bacon ranch casserole is a casserole made of yummy chicken, bacon, and ranch flavors. The base is made of chicken, bacon, ranch dressing, and cheese and then you can decide what vegetables you want to add.
So what makes this one of the best low carb chicken meals? The preparation is seriously the easiest thing ever. You cannot get it wrong.
If you have the chicken and bacon pre-cooked, and ranch dressing pre-made, then the prep time for this low carb chicken casserole literally takes just five minutes. You can even save more time by using rotisserie chicken, pre-cooked bacon bits, and store bought ranch.

Ingredients You’ll Need
This section explains how to choose the best ingredients for keto chicken bacon ranch casserole, what each one does in the recipe, and substitution options. For measurements, see the recipe card below.
Basic Ingredients For Chicken Bacon Ranch Casserole:
The common, simple ingredients are the best part of this low carb casserole. I often have them on hand, and I’ll bet you do too. And like many easy keto recipes, there are some options for customizing this one.
Here is what you’ll need for virtually any healthy chicken bacon ranch casserole recipe, and some customization options:
- Chicken Breast – It needs to be cooked, and seasoned with at least salt and pepper, but otherwise any kind of chicken will do! I usually use baked chicken breast, shredded chicken made in the Instant Pot, or pan seared chicken breast. This recipe is also a great way to use up leftover chicken you already have, or for a shortcut, buy a rotiserrie chicken… and (boom!) you get one of the easiest keto shredded chicken recipes ever.
- Bacon – Also needs to be pre-cooked until crispy, but there are several options here. I prefer to make bacon in the oven because it makes a large batch to use for multiple recipes, but you could also make air fryer bacon, stovetop bacon in a large skillet, or microwave bacon. If you want convenience, buy pre-cooked bacon bits.
- Garlic – You can buy fresh garlic and mince it yourself, or use jarred garlic to save time.
- Ranch Dressing – If possible, choose a dressing that’s on the thicker side for best results. I was excited to share another use for homemade ranch dressing, so that’s what I used. Making your own only takes a few minutes to whisk together, and stores well in a jar in the fridge, so try it if you can! But if you prefer to buy dressing, you’ll love this store-bought ranch, made with natural ingredients. You can even add some extra homemade ranch seasoning mix to the casserole if you want a stronger ranch flavor. For a variation, try substituting alfredo sauce instead of the ranch.
- Vegetables – They can be fresh or frozen, but there are so many options here that I decided to cover them in a separate section below.
- Shredded cheese – Choose your fave cheese! This easy low carb casserole works well with any kind. I had cheddar and mozzarella cheese around, as always. Feel free to use some fancy sharp cheeses if you like those (check out the cheese list for ideas!), but mozzarella and cheddar cheese are reliable options for the most family-friendly version.
Vegetable & Other Filling Options:
I originally made this keto chicken bacon ranch casserole using frozen spinach. For the most part, readers have been happy with it (you’ll love it if you like creamed spinach!), but I know some people don’t like spinach as much as I do. The most common variation I heard people making was a chicken bacon ranch casserole with broccoli, so I updated the recipe card with a 2nd version to show you how to do that.
Ultimately, this is your casserole, so make it yours, using vegetables you like. Here are some ideas:
|Healthy Low Carb Options||Higher Carb Options|
(penne pasta is a popular choice)
(either as florets or cauliflower rice)
|Green Beans||Sweet Potatoes|
No matter what veggies you use, there are three main things to know:
- Use the right amount. A good rule of thumb to use for this recipe is 4 cups of most vegetables, or 2 cups of cooked down greens (like spinach or kale). You can use the 4-cup rule as well if you are adding in pasta, roasted potatoes, or rice. If you want a more veggie-heavy casserole, increase the veggies to 6 cups and add an extra few tablespoons of ranch dressing.
- Precook your veggies. Vegetables will not cook through in the assembled casserole, and doing so can make the dish very watery, so avoid these issues by cooking your veggies before adding them to your chicken bacon casserole mixture. (The exception is frozen spinach, because this is already blanched and just needs to be drained.) When I make chicken bacon ranch casserole with broccoli, I simply cook the broccoli in boiling water and this works great. But if you prefer and have the time, you can also pan fry or roast your vegetables instead.
- Leftover vegetables work great. Low carb chicken casseroles are the perfect match for leftover veggies! If you have leftovers of sauteed or roasted vegetables, toss them into the casserole to use them up.
Below is an older photo of the version of this keto chicken casserole made with spinach, alongside a newer photo of the broccoli version. Both are delicious!
How To Make Chicken Bacon Ranch Casserole
This section shows how to make this keto chicken bacon ranch casserole recipe, with step-by-step photos and details about the technique, to help you visualize it. For full instructions, including amounts and temperatures, see the recipe card below.
- Cook veggies. This applies to broccoli and most other vegetables. If you’re using frozen spinach, you don’t even have to do that — just drain it and squeeze with paper towel.
- Mix. In a large bowl, combine cooked chicken, cooked bacon, cooked veggies, shredded cheeses, minced garlic, and ranch dressing.
TIP: If you like extra ranch flavor, add 1-3 teaspoons of ranch seasoning mix, in addition to the dressing.
- Assemble. Transfer your keto chicken casserole mixture to a baking dish (this one is a perfect size) and sprinkle with more cheese. (You can spray the pan with cooking spray or coat with butter, but I usually don’t find this necessary.)
- Bake. Baking time takes only about 15 minutes, just until the chicken bacon casserole is hot and bubbly. Voila! This will be one of your favorite low carb meals for a busy weeknight. (I added a bit more crumbled bacon on top at the end.)
How To Make Chicken Bacon Ranch Casserole Ahead
Like many casserole recipes, you can make this one ahead or freeze it. This chicken bacon ranch casserole is great for meal prep! Here are your options for storing this easy keto meal:
- Assemble ahead of time. You can assemble the whole thing, cover with foil, and keep it in the fridge for a few days. Then, simply bake right before serving.
- Freeze. Assemble it the same way, and freeze right in the casserole dish. You can bake it from frozen, but it will cook more evenly if you let it thaw in the fridge first. You may need to give it a good stir after baking, or midway through.
- Meal prep. Assemble in individual containers and heat individually for lunch. Since all the ingredients are pre-cooked, you can even reheat in the microwave if needed.
- Store leftovers. If you already baked the keto chicken casserole and have leftovers, simply store them in the fridge for 3-5 days.

- Baking Dish – Assemble and cook the keto chicken casserole right in this baking dish. It goes from oven to table beautifully, is an ideal size, and you can even freeze it if you want to prep the casserole ahead.

If using frozen broccoli and cauliflower, do I steam in microwave first or just mix in frozen? Sounds so tasty, can’t wait!!!!

Hi Abeni, Make sure to cook and drain your veggies first, before adding them to your chicken bacon casserole mixture.
WOW WOW WOW… This was delicious. Your ranch dressing was out of this world… I liked it better than the regular name-brand ranch. Thank you for sharing your recipes. I CAN HARDLY WAIT TO TRY MORE…
I made this for the first time tonight and absolutely loved it. I used cooked cubed chicken and fresh spinach. My husband had a second helping! Thank you, Maya, for a wonderful recipe. This is definitely going into my favorites.
I love this recipe. Very easy to make and taste great.
PROBLEM??? Your website doesn’t like the password I wrote down and there is no provision for ‘forgot password’ and it won’t let me create another account since it says my email has already been used. HELP PLEASE – Thanks.

Hi Dee, Please use the Contact Form and I will get you assistance ASAP.
If using a ranch packet would I make it into the salad dressing or just use the packet?
Wholesome Yum D0
Hi Melissa, You would just use the powder of the ranch packet.
I just made this tonight, and my husband and I both loved it! I used both frozen broccoli and frozen spinach. You definitely need to press the spinach to try to drain the excess water. Thanks for a recipe I will use again and again.
Can u make this a fridge meal, prep in the morning, and cook in the evening?
Wholesome Yum D0
Hi Quinette, Yes, you could definitely do that!
Great casserole! Instead of liquid ranch dressing, I used a packet of ranch powder. Also added pepper and used frozen broccoli lightly sautéed with chicken. Kids and hubs love it!!
This casserole is wonderful, and it’s become part of our regular rotation, I serve it with delicious low carb biscuits. I’ve always made it with broccoli but think spinach would be delicious as well. I probably add slightly more ranch than the recipe actually calls for. Love it!
Loved this recipe! It’s now one of our faves. Thanks!
Do not use frozen spinach in this. It was terrible. Perhaps it had some promise with broccoli, but otherwise no.
Wholesome Yum M0
Hi BJordan, Sorry this recipe didn’t turn out as expected. I’ve made this recipe using frozen spinach and it comes out nicely. Definitely drain the excess liquid off before adding to the pan so it doesn’t end up too watery.
I added a little half n half and mayo. Delish
Delicious! Used peppercorn bacon which gave it a small kick. May add a red bell pepper next time just for fun. Husband is not doing keto and also loved this. Thank you!
OMG!!!! This was absolutely wonderful. I especially liked that you used ranch dressing. That simple swap from other ingredients like cream cheese or even sour cream was a game changer. I did add some chopped chive’s I figured they are in ranch dressing so why not. I added a head of riced cauliflower along with everything else. I will be making this over and over again. Thanks so much for your creativity.
This looks delicious but I want to use up some cauliflower I have on hand. Has anyone tried this using cauliflower along with the broccoli? Would you follow the same directions or prepare the cauliflower any differently?
Wholesome Yum M0
Hi Pam, Cauliflower will work just fine in the recipe. I would try roasting the cauliflower with this method.
I don’t leave comments, but I got to give it to you, this is a great recipe. Even without the sourcream its great!. I forgot the sourcream, so I did it anyway, because the lemon helps to sour the mayonnaise. Great with tostones (fried plantains)
I really want to try this but not that keen on ranch dressing. Any other substitutes you could recommend?
Wholesome Yum M0
Hi Sally, I have several other dressings you could try in this recipe. They will each give their own flavors to the dish. Here are Blue Cheese Dressing, Thousand Island Dressing, and Caesar Dressing. I hope you find a combination you love!
Can I use raw cubed chicken and just cook it longer?
Wholesome Yum D0
Hi Felicia, I have never attempted to make the recipe that way so I am not sure how it would turn out.
Felicia, I would like to tell you that I made this for the first time tonight and used cubed chicken. Turned out great! Of course, I cooked the cubes first before adding to dish. I also used fresh spinach instead of frozen. Gives it a fresher taste.
This was amazing! Easy and delicious. Not too many ingredients, perfect to make with a rotisserie chicken. I’ll be making it again soon.
This recipe was absolutely AMAZING! I used 1 pound fresh spinach cooked in about 1 tablespoon butter and then I squeezed out the excess liquid. I used chicken pulled from a Costco rotisserie which yielded about 3/12 -4 cups. I added an extra 1/4 cup of ranch for a total of 1 cup. My family devoured it and said it needs to go to our “keep book!” I will also be adding it to my daughter in laws cookbook I am putting together for her because it is that yummy!!
I used fresh spinach also, but didn’t cook it, just mix all together and straight to the oven, came out great.
Great recipe but I thought it called for too much cheese. So I substituted 1/2 the cheese in the recipe with ricotta cheese. It came out great and lightened things up. I think I will try a ranch seasonings packet next time. Will definately make this again!
We loved this with frozen spinach and chicken thighs!
Was yummy but too much cheese! Never thought I’d say that about a recipe. I did not feel healthy eating it.
This was absolutely delicious. I’m new to keto and have made several of your recipes and they’ve all been very good. Thank you!
Love love love this recipe! My husband does the keto diet…. so this is perfect and something different then just meat! Literally devours the entire casserole by himself!
I want to add chopped onion and fresh mushrooms to it. would you recommend sautéing them first or adding them raw?
Thanks again! Love all your recipes! ❤️
Wholesome Yum M0
Hi Jennifer, So glad you enjoyed the recipe! Yes, if you are adding strong flavors like onion and mushrooms, I would sautee them first.
I made this recipe the other day it was very yummy. I might have put too much garlic in it thou. I think it’s cause they weren’t minced but other than it being garlicky I loved it and so did my fiance, he ate it up. I think next time I will use less garlic or mince it up so it won’t seem like too much but I will be making more of your recipes they all look so good and with all low carbs a great start for my diet thanks for the free recipes.
Hi, How many servings are in the casserole?
Wholesome Yum M0
Hi Erin, This recipe makes 8 servings.
Made this tonight for my mother who is normally picky and she said it was amazing.
I loved it & my family loved it, with broccoli! This will definitely be a frequent dinner.
I just purchased your cookbook and have been browsing recipes here and I noticed you use frozen spinach instead of fresh. Does fresh work as well or is there a reason you use the frozen?
Wholesome Yum M0
Hi Sherri, Yes, fresh or frozen will work in this recipe!
I’d like to attempt this in the crockpot. Thoughts? I would just throw everything in and let it cook min 6 hours in low.
Wholesome Yum M0
Hi Steph, Yes you can assemble this in a crockpot. All the ingredients are already cooked, so you really just need to heat the ingredients through. I would combine all your ingredients into the slow cooker vessel, and set to low for 4 hours.
I LOVE THIS!!!! I fixed it for a funeral potluck and it was the favorite dish and everyone kept asking for the recipe. Love love love it!
We made this recipe last night for the whole family and everyone loved it. The meal was easy to make and it was delicious. We will definitely make this one again! Thank you!
This is in my weekly meal prep line up. Easy and very good!
I am making this recipe, this weekend. I am beyond excited to find new keto recipes. I’ve plateaued and need a refresher.
Hi how long can you freeze it for please
Wholesome Yum M0
Hi Sonia, Yes you can freeze this recipe. Properly stored, it will keep for 2-3 months. Enjoy!
Made this the other evening with broccoli, made ranch from the hidden valley packet, was amazing,
My girlfriend and I love this dish
It was faaabulous!
Curious. I am looking to do week long meal prep as work/life is keeping me quite busy. So I am looking for recipes that I could cook on sunday, divide up and individually freeze and reheat throughout the week. If I were to do that with this.
Would throwing maybe 2-3 in the fridge and the rest in the freezer be ideal? I know it said it would be good for say 5 days in the fridge so I figured maybe the next couple days would be good in the fridge and the rest frozen?
Any thoughts or suggestions?
Wholesome Yum M0
Hi Jason, Yes! That works great! Just be sure to take out your individual servings the night before you need them. They reheat better from cold than they do from frozen.
I love all these ideas!
Very good casserole. I made 4 servings, as I live alone. I am used to cooking a big batch of something and eating it for supper most of the week. When I went keto, I felt like I was cooking and doing dishes for hours every day. This is the first casserole I’ve tried, and I enjoyed it very much.
This recipe is super yummy! It was a crowd favorite! I used yogurt based ranch which is low calorie. It came out delicious. I used a little bit more ranch because it was a little dry, but it was super delicious
I also used both broccoli and spinach
Even my picky husband liked it.
I liked the dish very much, I didn’t make with broccoli though.
This was DELISH! Made it with the broccoli, and it hardly took any time at all to prepare – really filling too!! Will make again, but I’ll try the spinach next time! 😉
NOM.NOM!! very tasty
It was delicious! I made it for just myself because my husband doesn’t like chicken or spinach. & it was great!
My only question is about the serving sizes & nutrition. I followed the recipe for 8 servings but the suggested 1 cup serving size was 1/4 of the dish. Which in turn doubled the calorie count of what constitutes a serving.
However, that doesn’t change how much I enjoyed it & how easy it was to make.
Wholesome Yum M0
Hi Tara, I am so glad you enjoyed the recipe. Because there are two variations to the recipe, it can be difficult to get an exact 1 cup serving size each time. It is best to divide the recipe into 1/8th portions instead of measuring it into a cup.
I made this exactly as written, using steam-in-the-bag broccoli, pre-cooked bacon, minced jarred garlic, and bottled ranch dressing. It was delicious! My picky daughter even had seconds, which is about as high a compliment a recipe can get!
This was so delicious and so easy to make. Even my 1 year old loved it! I made mine with broccoli and will absolutely make again!
I made this for dinner tonight using rotisserie chicken chunks with steamed broccoli. Subbed about 1/4 Cup of mayonnaise along with ranch dressing, everything else as per your recipe and we loved it! Ate more than we should have. Definitely a keeper, thank you!
