Today I want to share with you a keto breakfast casserole that I think you’re going to really enjoy making.

This is one of those recipes that makes breakfast so much easier, especially when you’re following a keto diet. It’s packed with eggs, sausage, and cheese, which means it’s full of protein and healthy fats to keep you satisfied all morning long.
The best part is that you can make it ahead of time and have breakfast ready for the whole week. Making a casserole might sound like a lot of work, but trust me, this one is actually very simple.

If you prefer ground beef instead of sausage, that works perfectly fine. You can add different types of cheese if cheddar isn’t your favorite.
The base recipe is very flexible, so don’t be afraid to make it your own. Just keep the eggs and cream the same, and you can adjust the other ingredients however you want.

👨🍳 How To Make
Follow this easy recipe:

Step 1
Start by preheating your oven to 350F / 175C and heating a large skillet over medium-high meat. Add the sausage and cook the meat until it’s fully cooked. Don’t overcook. Use a wooden spoon to break the meat apart while cooking.
Step 2
Spread the sausage over the bottom of the dish – I used a 9×13-inch glass casserole dish.
Step 3
Take a large bowl and whisk the eggs, heavy whipping cream, hot sauce, and shredded cheese. Evenly pour the mixture over the sausage.
Step 4
Bake for 35-40 minutes. Enjoy!!

💡Tips
1. Don’t Overcook Your Sausage
When you’re browning the sausage in the skillet, cook it just until it’s no longer pink, then stop.
A lot of people make the mistake of cooking the meat too long because they want to make sure it’s done, but if you overcook it at this stage, it’s going to cook even more in the oven and end up dry and tough.
The sausage will continue cooking when the casserole bakes for 35-40 minutes, so you really just need to get it cooked through initially. Break it up into small pieces with your wooden spoon while it cooks so it browns evenly.

2. Whisk The Eggs Really Well
This might seem obvious, but you need to whisk the egg mixture thoroughly until everything is completely combined and smooth.
Don’t just stir it a few times and call it done. You want the eggs, heavy cream, hot sauce, and cheese to be fully mixed together with no streaks of egg white or clumps of cheese sitting at the bottom of the bowl.
This usually takes about a minute of good whisking. When everything is properly mixed, you’ll get an even texture throughout the whole casserole.

3. Let It Rest Before Cutting
Letting the casserole rest for 5-10 minutes after it comes out of the oven makes a huge difference.
When it’s fresh from the oven, the eggs are still really hot and haven’t fully set up yet. If you try to cut into it immediately, it will be loose and messy, and the pieces will fall apart or ooze liquid.
The eggs need a few minutes to firm up as they cool slightly. During this resting time, everything settles and binds together properly, so when you cut into it, you’ll get nice clean squares that hold their shape.

FAQ
Can I use ground beef instead of sausage?
Absolutely, ground beef works perfectly in this recipe. In fact, many people prefer it because it’s often cheaper than breakfast sausage or because they just like the taste better.
The cooking process is exactly the same – brown the ground beef in your skillet, breaking it up into small pieces, until it’s no longer pink.
