Most people might not think about making egg casserole without bread or potatoes, but you won’t even miss them when you make my keto breakfast casserole. It’s a delicious way to start your day on a good note… and an easy one. It comes together quickly with simple ingredients you’ve got on hand, the texture is wonderfully fluffy, and it’s so satisfying. I hope this low carb breakfast casserole will become a staple at your house like it is in mine. Make it with me!
Why You Need My Keto Breakfast Casserole Recipe
- Savory, cheesy, and fluffy – My low carb breakfast casserole is like a big, cheesy omelette in a baking dish. If you love omelettes, you’ll love this one, too.
- Quick and easy – The prep is fast and there isn’t much to it. It’s perfect for weekend mornings or weekday meal prep (although my egg muffins and keto breakfast sandwiches are more portable if you need that). It also makes a wonderful holiday brunch with keto butter coffee and keto cinnamon rolls, keto pancakes, or almond flour waffles!
- Keto friendly and gluten free – My keto breakfast casserole has just 3.2g net carbs per serving… or 0.9g if you omit the broccoli.
- Endless customization options – I’ve got a formula below to let you customize this dish with whatever ingredients you like or have on hand. Make it yours!
Ingredients & Substitutions
Here I explain the best ingredients for my easy keto breakfast casserole recipe, what each one does, and substitution options. For measurements, see the recipe card.
- Meat – I used breakfast sausage to make this a sausage, egg and cheese casserole, but bacon (my baked bacon or air fryer bacon are easy options to cook it, ham, or even chorizo work great. You’ll need to pre-cook your meat, whichever meat you choose.
- Veggies – Vegetables are optional, but I’m a huge fan of including them. I used broccoli, but you could use bell peppers (roasted red bell peppers are delicious!), asparagus, onions, spinach, celery, a mix of broccoli and cauliflower, or any other keto veggie you like.
- Eggs – For the fluffiest texture, let them come to room temperature. If you forget, you can place them in a bowl of warm water to come to room temp quickly.
- Heavy Cream – This makes the eggs more fluffy and rich. Any keto milk will work. If you want your low carb breakfast casserole dairy free, use full-fat coconut milk instead (and skip the cheese), or use lighter almond milk.
- Cheese – I prefer shredded cheddar cheese in this keto egg bake, but any kind you’ve got will work. Try mozzarella, American, Swiss, or Monterey jack.
- Garlic – I recommend mincing fresh garlic, as it will have a sweeter and more potent flavor. But, you can substitute 3/4 teaspoon garlic powder and add it when whisking the eggs instead of sauteing.
- Fresh Parsley – Oregano or basil also work well. If you use dried herbs (either individually or an Italian seasoning blend), use a teaspoon of instead.
- Salt & Pepper
For other combinations of meat and vegetables, see the formula I use for all my keto breakfast casserole recipes below!

How To Make Low Carb Breakfast 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.
- Saute the garlic. In a greased large skillet over medium-high heat, cook the minced garlic until fragrant.
- Brown the meat. Add the sausage. Cook, breaking apart with a spatula, until browned. Meanwhile, preheat the oven.
- Cook the veggies. If using broccoli (or other veggies), blanch in boiling water until crisp-tender. Plunge them into an ice bath to stop cooking. Drain and pat dry. (You can also roast the veggies, or cook them any other way you like.)
- Whisk the egg base. In a large mixing bowl, whisk together eggs, heavy cream, cheddar cheese, parsley, sea salt, and black pepper.
- Assemble the casserole. Grease a large casserole dish. (The one I use is sturdy and beautiful — available at Amazon or Target.) Arrange the cooked sausage and veggies evenly at the bottom. Pour the egg mixture on top, then sprinkle with more cheese.
- Bake until set. I like to garnish my keto breakfast casserole with fresh herbs for a pop of color!
My Formula For Any Fillings
This keto breakfast casserole works with any kind of meat, veggies, cheese, or milk you like! Just use my formula for the amounts:
- 1 pound cooked meat
- 6 cloves garlic
- 3 cups cooked veggies
- 12 large eggs
- 1/2 cup cream
- 2 cups shredded cheese
- 2 tablespoons fresh herbs
- 1/4 teaspoon each salt & pepper
My Recipe Tips
- The baking time will vary depending on your pan. The material can have an impact, and especially the size. I use the larger dish from this set. Smaller pans will take much longer — just keep baking until the eggs are set.
- Want to leave out the meat or veggies altogether? My formula above includes both. If you want to omit the meat, add an extra 2 cups of cooked vegetables. If you want to skip the veggies, replace them with 1 to 1.5 pounds of meat.
Make Ahead Options
- Store in the fridge: Assemble the keto breakfast casserole ahead of time (without baking it), cover in plastic wrap, and store in the fridge for up to 3 days. Just bake when you’re ready! I find it cooks more evenly if you let it sit at room temperature for 15-20 minutes before baking.
- Freeze before baking: Same as above, but I use an extra layer of aluminum foil over the plastic wrap for freezing for up to 3 months.
- Freeze after baking: I recommend freezing this casserole before baking if you can (above), as the texture is better, but you can freeze after baking, too. I use this method when I want to freeze individual portions to meal prep and reheat. Wrap them individually in plastic wrap and freeze in a zip lock bag for up to 3 months.
- How to reheat: If your casserole is frozen, let it thaw first. Then, bake for the usual time in my low carb breakfast casserole recipe if it’s uncooked. If it’s already cooked, it takes 20-30 minutes at 350 degrees F for the whole casserole, or 5-10 minutes for individual pieces. The oven is much better than the microwave, which can be drying or leave it watery.

-
In an oiled skillet over medium-high heat, cook the minced garlic for about one minute, until fragrant.
-
Add the breakfast sausage. Cook for about 10 minutes, breaking apart with a spatula, until browned.
-
Meanwhile, preheat the oven to 375 degrees F (190 degrees C).
-
If using broccoli (or other veggies), blanch them in boiling water for about 5-7 minutes, until crisp tender. Then plunge into an ice bath to stop cooking, drain and pat dry.
-
In a large bowl, whisk together the eggs, heavy cream, half of the cheddar cheese, parsley, sea salt, and black pepper.
-
Grease the bottom of a glass or ceramic 9×13 inch (22×33 cm) casserole dish (I use this one), or 9×9 dish without the broccoli. Arrange the crumbled sausage evenly at the bottom of the casserole dish. (If you want to add any broccoli or pre-cooked vegetables to your casserole, mix them with the sausage at this step.)
-
Pour the egg mixture over the sausage. Sprinkle the remaining cheddar cheese on top.
-
Bake for approximately 30 minutes, until the eggs are set and cheese is melted.

Keto Breakfast Casserole

0It indicates that a 3×3 square is one serving, and the whole thing has 9 servings. That’s less than 2 eggs/serving. Is this designed to consume something else with it? Is it ok to consume more and still loose weight? That 3×3 is only 1 carb.
I guess I wonder with much of these sort of “eat as much as you want as long as it’s low/no carb” diets, at what point is something “too much”?
Maya | Wholesome Yum
0Hi Lynn, There is more in the casserole than just eggs, so it’s still pretty filling with the meat, cream and optional veggies in there. But, you can definitely have more than 1 serving depending on what else you have that day. It’s possible to gain weight on any diet, even keto or low carb, so I wouldn’t look at any diet as “eat as much as you want” – BUT keto and low carb diets regulate hunger and blood sugar, making overeating much less likely. Some people still find it necessary to count all their macros and total calories, while others are fine just eating keto/low carb foods.
Michael Elmore
0I really like this recipe. I doubled the meat, drained it, then put it back in the pan with 8oz of cream cheese until melted in. I also opted out of the broccoli . Taste great!
Maya | Wholesome Yum
0I am happy you liked it, Michael! Please come back again soon!
Christine Westfall
0Delicious! I love having simple keto recipes! Is has been the key to my success staying on it these last 7 months. I tried going keto last year and got off because some of the recipes were too complicated, took too long, and were not as good as I thought they would be. so glad that there is much more information out there now.
Maya | Wholesome Yum
0I am so happy you liked the casserole, Christine! Thanks fro stopping by!
TL
0Loved this! Made this for a brunch attended by a friend on the keto diet and she gave it 5 stars. Decided to make it “Denver omelette” like with cubed ham, green pepper and onion. So good!
Maya | Wholesome Yum
0I am so happy you liked it! Please come back again soon!
Stacy
0I just prepared and baked this 6 ingredient, low carbohydrate egg, sausage and cheese casserole. It’s actually quite good! The eggs set perfectly (I left the casserole in the oven for just an additional 2 minutes; 30 minutes in my oven wasn’t quite long enough.) and the sausage and garlic (plus the yummy cheese, of course!) combination makes it super flavorful. I’ll be trying other recipes, as long as they are low carbohydrate. It is my way of eating and the only diet I really feel healthy eating. My doctor is on board too – I had spoken about it a few years back because I was concerned about too much protein consumption with only one kidney. I’m good to go and that’s awesome because I love eggs and all the low carb options available!
Maya | Wholesome Yum
0I am so happy you liked the breakfast casserole, Stacy!
Georgia
0I am about to try this recipe but want to know if I can mix it all up at night and cook it the next morning. Or should it be cooked right away and reheated the next day? Thanks.
Maya | Wholesome Yum
0Hi Georgia, Yes, you can mix it the night before and cook in the morning! That usually has a better result than reheating, but you can do either.
Eugene
0Easy to make and tastes delicious even after being frozen! Being fairly new to cooking, I was a little shocked at how great it looked and tasted!
Maya | Wholesome Yum
0I am so happy you liked it, Eugene! Thanks for stopping by!
Derek
0Turned out pretty bland IMHO, so I doubled the sausage, added onions and bell peppers to the pan with the sausage, added cayenne, dropped the salt and replaced with a good bit of Cajun seasoning (Tony’s or the like). Topped with generous Louisiana style hot sauce when serving.
Now that’s breakfast.
Maya | Wholesome Yum
0Hi Derek, Thank you for sharing – that sounds delicious! The recipe was designed to act as a base that you can customize any way you like. I do plan to update it a little soon to add some veggies, as I think it would be better and more balanced that way.
Lisa
0Not sure if I’m missing something but at what point do you add the cloves?
Maya | Wholesome Yum
0Hi Lisa, It’s 6 cloves of garlic. They get added in step 1 of the instructions.
Meri
0Hi Maya
Do I use breakfast sausages or just the mince out of the breakfast sausage?
I can’t break up the sausage as per the instructions, I would have to dice the sausages.
Regards
Meri
Maya | Wholesome Yum
0Hi Meri, dicing the sausage would work just fine. The point is just to not have full sausages in the casserole.
Amanda
0What kind of cheese would you recommend, does it have to be reduced fat or fat-free cheese to keep the nutrition facts that are listed up here?
Maya | Wholesome Yum
0Hi Amanda, I use full-fat cheddar cheese for this recipe. If you use a different kind, it will probably change the nutrition facts.
Nancy Maas
0I’m guessing this could be put together the night before and kept in the refrigerator until ready to bake?
Half and half is okay instead of heavy cream, right?
Maya | Wholesome Yum
0Hi Nancy, Yes to both of your questions! 🙂
Lindsay Rivers
0How much would you consider to be a serving?
Maya | Wholesome Yum
0Hi Lindsay, one serving would be a 3″x3″ piece of the casserole.
Kristen
0Hi Maya! I made this Christmas morning and it could not have been easier or more delicious. No subs or additions this time, but this casserole would be a great blank canvas with different veggies or types of sausage. Thanks for all your recipes and Happy New Year!
Maya | Wholesome Yum
0Thank you so much, Kristen! Happy New Year to you as well!
Firttimer
0Hi, looking to make this for Christmas morning but wanted more for the family. If I use a 9×13 dish can I just double the recipe and assume cooking time is about the same? Thanks!
Maya | Wholesome Yum
0So sorry, I just saw this! Yes, that should work fine! It might take a little longer to cook, but not by a lot.
Teresa
0The cooking time is all wrong. Cooked it for 30 minutes and the top was done, but the egg mixture was still very uncooked. I only found out when I attempted to serve it.
Suzanne Lanoue
0I have the same problem. Not all ovens are the same. You just keep cooking it for 5 minutes at a time until it comes out cooked. You could also try increasing the temperature to 400. It’s difficult to keep it balanced without burning the top.
I have made it quite a few times now. You can use milk or even eggnog instead of cream and it still turns out great. You can use different types of sausage and cheese, too. If you use a sausage that doesn’t break apart, then chop it into very fine pieces or else the texture is very different. Or possibly even grind it or use a food processor. If you use a sausage that is fully cooked, you don’t even have to cook it ahead of time – you can skip that step. If your sausage already has garlic in it, you can skip that part, too.
I freeze each square to make a quick breakfast during the week! Great recipe, especially for those of us who have to eat gluten free and low carb.
Maya | Wholesome Yum
0Thank you, Suzanne! That’s exactly right in terms of the cooking time. A higher temperature will likely burn it, so you could cook it longer at the lower temp, or if you increase the temperature, just cover it with foil once it starts to brown on the top.
Brian
0What temp do you recommend?
Maya | Wholesome Yum
0Baking temperature is 375 degrees. Thank you for stopping by, Brian!
Rebecca
0When you freeze it. How do you heat it up the next morning?
Maya | Wholesome Yum
0I added freezing and thawing instructions to the post above the recipe card!
Maya | Wholesome Yum
0Hi Teresa, Sorry that happened. I’ve made this several times and it was always cooked through. Could it be that your oven runs cool or you used a different size baking dish?
Mary

0Can half and half be used in place of the heavy cream?
Maya | Wholesome Yum
0Hi Kathy, Yes, absolutely! The nutrition info would be a little different – less fat and a little more carbs.
Brenda Martin
0It does! Thanks!!
Traci
0How long does this keep in the fridge and freezer?
Thank you!
Maya | Wholesome Yum
0Hi Traci, I’ve kept it in the fridge for close to a week. Probably several months in the freezer.
