Keto Breakfast Casserole with Sausage

My family loves my Keto/Low Carb Sausage Ball Puffs, but sometimes I don’t want to take the time to scoop out every single one and bake them in batches. When my time is short, I can make this Keto/Low Carb Sausage Breakfast Casserole instead. It is basically the same recipe except I subbed out the cheddar cheese for Monterrey Jack cheese since that is what I had on hand today.

My hubby and big kids love spicy foods, so I made it with hot sausage. I’m pretty much a wimp when it comes to hot stuff, but the hot sausage was pretty mild. This Keto breakfast casserole warms up nicely in an air fryer or wrapped in aluminum foil in the oven.

I’m a little bit of a leftover snob as I want my food to taste as close as possible to fresh out of the oven so I rarely warm up foods like this in the microwave. However, my family enjoys this recipe so much; I’ll probably have to make two casseroles to have enough to last for a couple of days.

Ingredients:

  • Breakfast Sausage– Pork sausage is commonly eaten for breakfast in the United States. This sausage is usually seasoned with black pepper or sage. You can use mild or hot sausage in this recipe.
  • Butter– Compliments and enhances the flavor of the keto breakfast casserole. 
  • Coconut flour– Low in carbs and high in fiber, this flour works great as a keto-friendly ingredient.
  • Full fat sour cream– Keto-friendly, full-fat sour cream helps make this keto breakfast casserole extra creamy.
  • Eggs– Low carb and high protein, eggs make the perfect base of this keto breakfast casserole. 
  • Salt– Use as directed, a little goes a long way.
  • Baking powder– Helps create a light and fluffy breakfast casserole. 
  • Shredded Monterey Jack Cheese– I like to use Monterey jack as it is mild in flavor and melts well, but you can try other types of cheese as well. 

STEPS:

Step 1: Preheat the oven to 375 and grease a 9 X 13 casserole dish.

Step 2: Combine melted butter (I cool mine by popping the bowl in the fridge for 5 min), eggs, salt, and sour cream then whisk together.

Step 3: Add coconut flour and baking powder to the mixture and stir until combined.

Step 4: Incorporate drained browned sausage and shredded cheese.

TIP: Cheese is a great keto-friendly food, containing high amounts of fat, moderate protein, and low amounts of carbs. For keto recipes, I suggest that instead of buying pre-shredded cheese from the store, buy a block of cheese and grate it yourself. Pre-shredded cheese often contains additives that increase its total carb amount. By doing it yourself you can avoid those extra carbohydrates. 

Step 5: Stir until combined then pour the batter into the casserole dish.

Step 6: Bake for 20-25 minutes until it starts to brown a little around the edges.

Enjoy!

HOW TO SERVE KETO BREAKFAST CASSEROLE

While I love to use this keto breakfast casserole as a stand-alone meal, some prefer a little something extra to go alongside this for breakfast. In that case, you can easily whip up a batch of our keto biscuits. Just slice them in half, toast, and add a portion of this keto breakfast casserole to create a delicious and easy breakfast sandwich!

WHAT KETO SAUSAGE CAN I USE?

When making this keto breakfast casserole, you can add whatever meat you want, but I like to add sausage to mine. When choosing a sausage brand make sure it is keto-friendly and contains zero sugar. If you want to mix it up, you can also add bacon or ham to the keto breakfast casserole instead. 

CAN I ADD VEGETABLES TO MY KETO BREAKFAST CASSEROLE?

Following a keto diet can make you feel limited when it comes to the vegetables you can eat. Adding vegetables in the keto breakfast casserole is 100% optional, but adding them can add additional flavor and make this already healthy dish healthier. The original recipe does not call for veggies, but now I like to make it both ways. If you do decide to add some of my low-carb favorites. 

Vegetable Options:

Option 1: Spinach is a green leafy vegetable that is packed with health benefits. One cup of cooked spinach contains more than 10x the recommended daily intake of vitamin k!

Option 2: Mushrooms are extremely low in carbohydrates and also have been shown to contain anti-inflammatory properties. 

Option 3: Avocado, is a high-fat fruit that will pair well with this mildly spicy keto breakfast casserole.

  1. Could anyone who mage these in muffin tins tell me how long they cooked them for and did you keep the temp the same?

    Really delicious and what I was looking for! I had brunch for my family over Hanukkah and I made a sausage casserole with traditional biscuits as a base. It was a big hit and I really loved it, but now that the holidays are over I am trying to get my eating back on track. I was craving that casserole this morning, but knew I had to leave the biscuits out. I found your recipe, and while making it, I thought I would try using the batter as a crust/base, and just putting the sausage and cheese on top. I doubled the batter to cover the bottom of the pan, and used turkey sausage. It turned out fantastic! I think it’s even better than the canned biscuit recipe. Yum!

    Really liked this recipe but it seemed a little flat- could you put it in a smaller pan to make it thicker?

    1. Sure! Feel free to use any size baking dish you prefer that gives it the height you’d like.

    1. I haven’t tried this recipe with almond flour. The general conversion is 1 to 4 coconut to almond flour. It is not an exact science though, so you will just have to try it out and see what you think. Let me know how it goes! Hope you enjoy it!

    1. The conversion is not an exact science, and I haven’t tried converting this specific recipe. However, the general conversion is 1 to 4 coconut to almond flour. Let me know how it turns out!

  4. Could you please include sodium facts in your recipes? I have several I want to try but all are missing the sodium info.

    1. Hey Monica, thanks for the question. I only include basic macros on my recipes. TO get the sodium you can plug the ingredients onto an nutritional app. This would get you the info you’re looking for. Thanks!!
