How to Make Keto Breakfast Casserole
Whipping-up my easy Keto Breakfast Casserole is easy peasy and doesn’t take much time. The combination of breakfast sausage, eggs, and cheese comes together in just a few steps. Once done, you’ll have a warm and comforting breakfast (or dinner!) ready to go. Here’s what you’ll need to have on hand.
Ingredients
- Breakfast Sausage: Adds savory flavor and protein. Breakfast sausage is a great keto-friendly option with minimal carbs.
- Large Eggs: The base of the casserole, eggs provide a good amount of protein and healthy fats.
- Shredded Cheddar Cheese: Gives the casserole that deliciously melty, cheesy texture that pairs perfectly with the sausage.
- Heavy Whipping Cream: Adds creaminess and helps create a fluffy texture while contributing healthy fats.
- Frank’s Red Hot Sauce: Adds a little kick without overpowering the dish. You can adjust the amount for your preferred level of spice.
- Salt and Pepper: Simple seasonings that enhance the overall flavor.
- Green Onions (optional): These provide a pop of color and extra flavor when sprinkled on top as a garnish.
Step-by-Step Instructions
Step One: Preheat the oven to 350°F (175°C). This ensures the casserole bakes evenly in a preheated oven.
Step Two: Heat a large skillet over medium-high heat. Add the breakfast sausage to the skillet, breaking it into small pieces with a wooden spoon. Cook the sausage thoroughly, about 5-7 minutes, until it’s no longer pink.
Step Three: Spread the cooked sausage evenly over the bottom of a 9×13-inch casserole dish. This will be the foundation of your keto casserole.
Step Four: In a large mixing bowl, crack the eggs and whisk them until smooth. Add in the heavy whipping cream, hot sauce, and shredded cheddar cheese, and whisk again until everything is combined.
Step Five: Pour the egg mixture over the sausage in the casserole dish, spreading it evenly to ensure it cooks consistently.
Step Six: Bake in the preheated oven for 30-40 minutes, or until the casserole is firm and cooked through. You can check doneness by inserting a knife into the center—it should come out clean.
Step Seven: Once cooked, remove the casserole from the oven and allow it to cool slightly. Garnish with green onions, if using, and serve warm.
Substitutions and Variations
One of the best parts of this keto egg casserole is its flexibility. You can easily make substitutions or add variations based on what you have on hand or your personal preferences. Here are a few ideas:
- Cheese: While cheddar cheese is a great option, you can switch it up with mozzarella, Swiss, or even pepper jack for extra flavor.
- Meat: If you don’t have breakfast sausage, feel free to use Italian sausage or even keto bacon. Both add a savory element that works well in this keto breakfast recipe.
- Vegetables: Fresh spinach, red bell peppers, or green chiles can be added to incorporate more nutrients without adding many carbs. Just be sure to chop them into small pieces so they mix evenly with the egg mixture.
- Dairy-Free Option: You can substitute the heavy cream with coconut cream and use dairy-free cheese for those looking for a dairy-free option.
- Spice Level: If you enjoy spicier foods, you can add more hot sauce or even some jalapeños to kick up the heat.
Best Tips
- Use Room Temperature Ingredients: Bringing your eggs and heavy cream to room temperature before mixing helps them incorporate better, resulting in a smoother texture in the final dish.
- Cook the Sausage Thoroughly: Make sure the breakfast sausage is fully cooked before adding it to the casserole dish. This ensures you don’t end up with any undercooked bits.
- Don’t Over Bake: Keep an eye on the casserole during baking. Over-baking the recipe can cause the eggs to dry out. It’s ready when the center is firm but still has a slight jiggle.
- Add Extra Flavor: For a more flavorful casserole, try adding onion powder or garlic powder to the egg mixture. These seasonings complement the sausage and cheese well.
- Make It Ahead of Time: This casserole can be prepared ahead of time. Simply assemble everything in the casserole dish, cover with plastic wrap, and store in the refrigerator until you’re ready to bake.
How to Store Keto Breakfast Casserole
If you have leftovers or want to prepare the casserole ahead of time, here’s how to store it:
- Refrigerator: Store the casserole in an airtight container in the refrigerator for up to 3-4 days. You can reheat individual servings in the microwave or oven for a quick breakfast.
- Freezer: This casserole freezes well. After it cools, slice the casserole into individual servings and wrap each piece in plastic wrap or aluminum foil. Place the wrapped portions in a freezer-safe container or bag, and freeze for up to 3 months. Thaw in the refrigerator overnight before reheating.
- Reheating: To reheat, simply pop a slice in the microwave for 1-2 minutes, or reheat the entire dish in the oven at 350°F (175°C) until warmed through.

As Keto goes this is a very straightforward easy recipe.
Using heavy cream in place of butter adds a nice smooth texture to this casserole.
I slightly warm the cream and blend a philly cream cheese into it. Then mix in the eggs to take it to the next level.
I also add mushrooms onions and green peppers my own smoked ham and American cheese. Thanks for sharing your recipe. I enjoy it. Looked to add a pic but didn’t see the option.
Will it refrigerate overnight to bake in the morning?adding other veggies is a great idea.
Can you make it the night before?
Just remember that it’s very difficult to find sugar free sausage, Applegate makes some but they’re salty. So if you’re strict keto maybe substitute sausage with sugar free bacon, a little easier to find
That looks good! I’d definitely doctor the meat up with some seasonings, onions and pell peppers.
I would like freezing instructions.
Can this be made in the crockpot? If so, possible directions?!? Thanks!
