The only thing I might love more than quick, healthy meals and comfort food recipes is when I get to combine them in a dish that uses ingredients I have on hand. And low carb casseroles — like loaded cauliflower casserole, eggplant lasagna, and my personal favorite, this chicken bacon ranch casserole recipe — are perfect for just that.

The beauty of this one is that it doesn’t taste like good-for-you food at all. Cheese! Bacon! Ranch! What’s not to love? My whole family gets excited about this easy, real food dinner. But secretly? It’s packed with protein and veggies.

Why You’ll Love My Chicken Bacon Ranch Casserole

• Chicken, bacon, and ranch – Need I say more? They’re the flavors so many of us know and love. And it’s probably why my chicken bacon ranch casserole recipe has been so popular over the years.
• Simple, customizable ingredients – The best part is how common and flexible the ingredients are. You can easily adjust this recipe to use up whatever you have on hand. I often use it to clean out my refrigerator!
• Delicious way to enjoy protein and veggies – This chicken casserole feels like a total “mom win” for me. It’s one of the ways that my kids come around to new vegetables! With all the creamy, cheesy flavors, even your picky eaters will enjoy it.
• Healthy & low carb – It’s not just comforting and flavorful. It’s also keto-friendly (just 4.4 grams net carbs per serving using the broccoli option), gluten-free, and has plenty of vegetables. You can totally add starch if you want, though.
• Easy one-pan dinner – One of my favorite things about low carb casseroles is that your meal can be complete in just a baking dish. This one is a lifesaver on my busiest of days!
• Great for meal prep – Assemble it ahead of time and bake when needed, making your weeknights smoother. I love having it ready in the fridge, so dinner is just 15 minutes away.

Ingredients & Substitutions

Here I explain the best ingredients for my keto chicken bacon ranch casserole, what each one does in the recipe, and substitution options. For measurements, see the recipe card.

• Chicken Breast – It needs to be cooked, and seasoned with at least salt and pepper, but otherwise any kind of chicken will do! Somehow I always have extra cooked chicken, so I usually use leftover baked chicken breast, shredded Instant Pot chicken breast, roasted chicken, or pan seared chicken. This recipe is also a great way to use up ranch chicken, since the flavors are the same. For a shortcut, buy a rotisserie chicken and shred it. And if you prefer beef, see my beef casserole that I developed based on this one.
• Bacon – 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. For a lighter alternative, use baked turkey bacon instead. If you want convenience, buy precooked bacon bits.
• Ranch Dressing – This makes up the sauce for the chicken casserole. I was excited to find another use for homemade ranch dressing, and it will only take you 5 minutes to whip it up! If you prefer to buy it instead, I recommend the kind in the refrigerated section next to the produce — it usually tastes better, is thicker, and has cleaner ingredients. For a variation, try substituting my Alfredo sauce or Caesar dressing instead of the ranch.
• Garlic – Buy fresh garlic and mince it yourself, or use jarred garlic (or even 1/2 teaspoon of garlic powder) to save time.
• Shredded Cheese – Choose your favorite, because this easy low carb casserole works well with any kind! I always have cheddar and mozzarella cheese around, so that’s what I usually use. These are reliable for the most family-friendly version, but feel free to branch out to fancy sharp cheeses (check out my cheese list for ideas!).
• Veggies – They can be fresh or frozen, as long as you pre-cook them. You’ve got so many options here! I first made this dish using frozen spinach, which you’ll enjoy if you like creamed spinach, but I know not everyone is a fan. So, I made this chicken bacon ranch casserole with broccoli for my kids one day, and we all loved it so much that I updated the recipe to add that option. See my chart below for other vegetables you can use — I’ve tried so many combos over the years and they’ve all turned out great.

How To Make Chicken Bacon Ranch Casserole

I have step-by-step photos here to help you visualize the recipe. For full instructions with amounts and temperatures, see the recipe card.

1. Cook the veggies. I do this with broccoli and most other vegetables, so that they don’t make the chicken casserole watery. You can simply steam like I did below, but if you’ve got the time, roasted broccoli or sauteed broccoli tastes even better. If you’re using frozen spinach, you don’t even have to cook it — just drain it and squeeze well.
2. Mix all the ingredients. In a large bowl, combine the cooked chicken, cooked bacon, cooked veggies, shredded cheeses, minced garlic, and ranch salad dressing.

3. Assemble the chicken bacon ranch casserole. Transfer the 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.)
4. Bake until hot and bubbly. Voila! Your low carb meal is here to save your busy weeknight. I added a bit more crumbled bacon on top at the end this time, but green onions would also pair well with these flavors.

Below is an older photo of my original chicken casserole made with spinach, alongside a newer photo of the broccoli version. Both are delicious!

My Recipe Tips

• Use the right amount of vegetables. My rule of thumb is 4 cups of chicken and 4 cups of 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 1/4 cup of ranch dressing.
• Always precook your chicken, bacon, and veggies. This casserole bakes only for long enough to heat it and melt the cheese, not long enough to cook raw foods. Besides, adding raw meats or vegetables will mess up the texture. You can use any method to cook them, or even buy them pre-cooked. Which brings me to my next tip…
• You can take shortcuts with store-bought items. I’m not a fan of processed pre-made foods, but for this shredded chicken casserole, finding clean ingredients is easy. Grab a rotisserie chicken, a bottle of ranch, and some bacon bits, and this recipe becomes a breeze. You can even buy pre-cut veggies!
• Use a thicker dressing if you can. This coats the chicken and vegetables better than ones that are very runny.
• Leftover vegetables work great. Chicken bacon ranch casserole is the perfect match for leftover veggies! I make it all the time to use up extra sauteed or roasted vegetables.
• For a more intense ranch flavor, add 2 tablespoons of ranch seasoning. You can make my homemade ranch seasoning mix or use store-bought.
• Bake the casserole until it’s melty and bubbly. If it starts to brown too much on top, just cover it with foil. On the other hand, if you want to brown the cheese more, broil it.

Storage Instructions

• Store: Keep your leftovers in an airtight container in the refrigerator for up to 3-5 days. They taste amazing reheated for lunch all week!
• Meal prep: I meal prep this chicken bacon ranch casserole All. The. Time. You can assemble the whole thing, cover with foil, and keep it in the fridge for a few days. You can freeze it. You can portion it individually. It’s fantastic in all the ways.
• Reheat: To reheat the entire casserole, cover it with foil and bake at 350 degrees F for about 20 minutes. You can also warm up individual portions in the microwave.
• Freeze: Since everything is already precooked, I recommend freezing this chicken casserole before baking. Assemble it and freeze right in the covered baking dish for up to 3 months. You can bake from frozen, but it will heat faster and more evenly if you thaw in the fridge overnight. I recommend giving it a good stir after baking, or halfway through.

Serving Suggestions

One of the reasons I adore this chicken bacon ranch casserole is that it’s a full meal by itself! But if you’re in the mood for something extra, pair it with one of my low carb salads or a bowl of soup as a starter.
