You’ll love the fact that this is a dish that the whole family can eat, from those who are dieting to those who can eat whatever they want. I eat it all by itself, while my husband enjoys a piece of toast with it.

I highly recommend reading this entire post before you begin preparing the recipe. However, if all you want is the list of ingredients with full directions, please either click on the jump-to-recipe button above or scroll to the bottom of this post.

Low Carb Breakfast Recipe

Many people have embraced one of the many variations and ways of eating few carbs. This casserole is also called a low carb breakfast bake. Whatever you want to call it, this is an easy low carb breakfast casserole.

If you’re watching your carbohydrate intake, you’ll also enjoy these yummy egg bites. They’re best served hot with a sprinkling of parsley. Since I didn’t have fresh parsley, I used dried parsley from a jar.

When I’m cooking for just my husband and me, I’ll serve this casserole all by itself.

However, if there are other people at the table, I’ll add a few other things, like perhaps a fruit parfait or some scrumptious blueberry muffins to satisfy their taste buds. Although they’re not as low carb, they satisfy someone who wants more with their breakfast.

Breakfast Casserole Ingredients

This easy recipe only has a few ingredients. And you can find all of them in almost any grocery store.

Here are the items you’ll need for this delicious Keto breakfast:

pork sausage and shredded cheddar cheese
  • Pork breakfast sausage (or turkey sausage)
  • Large eggs
  • Half and half or heavy cream 
  • Shredded cheese (cheddar cheese or Colby cheese)
  • Salt and black pepper (optional)
bowl of eggs in shells
half and half

For exact measurements of each ingredient and full directions, go to the recipe card at the bottom of the page. You can even print out the card by using the “print” button.

I’ve used other types of cheese as well. In fact, feta cheese is delicious when it’s stirred into the eggs. When I do this, I still top the casserole with cheddar.

How to Make a Keto Breakfast Casserole

This breakfast casserole is a great way to have a healthy low carb breakfast that everyone will enjoy. 

avocado oil and baking dish

Preheat your oven to 350˚ F. Spray a baking dish with your favorite cooking spray.

I used avocado oil this time, but sometimes I use olive oil or butter. Set the prepared baking dish aside.

raw sausage in skillet

Put the sausage in a large skillet over medium heat.

mashing the sausage to make crumbles

With a meat masher, spatula, or spoon, break up the meat as it browns.

browned sausage

Once the meat browns, transfer it to a prepared baking dish.

Spread the meat out in an even layer. I use either a silicone or wooden spoon to do this.

whisked eggs

Next, crack the eggs in a large bowl bowl and whisk them until the yolks are mixed in with the whites. 

mixing half and half into eggs

Add the half and half or heavy whipping cream and add salt and pepper if you want.

Stir or whisk again.

shredded cheese in egg mixture

Pour 1/3 of the shredded cheese into the egg mixture and stir until the cheese is evenly distributed.

Now pour the egg mixture over the sausage and swirl the pan to have the egg evenly distributed.

Finally sprinkle the remaining shredded cheese over the top of the casserole as evenly as possible.

Bake for 25 to 30 minutes or until the eggs are firm and the cheese is melted, bubbly, and golden brown.

Remove the casserole from the oven and allow it to rest for 5 minutes before slicing into individual servings.

Serve hot.

How to Store Leftover Keto Breakfast Casserole

If you make this dish for the family or overnight guests, chances are, you won’t have leftovers. However, if you do, cover the baking dish in Saran wrap and put it in the refrigerator for up to 2 days.

I’ve found that this egg and sausage breakfast casserole is just as good the next day.

You can also freeze leftovers. Put the leftovers in an airtight container or freezer bags. It will be good for up to a couple of months.

Before reheating it, thaw it in the refrigerator overnight. Then either put it in the microwave on high for about a minute, the oven at 350˚ F for 10-15 minutes, or your air fryer at 340˚ F for 3 minutes.
