🔪 How to make a Keto Breakfast Casserole

You'll love how simple it is to make this low-carb breakfast casserole recipe. The meal prep takes 5 minutes and about an hour or less cooking time. Let's get started, shall we?

• Preheat oven to 350 degrees Fahrenheit (177 degrees Celsius).
• Heat the cast-iron skillet over medium-high heat. Oil is optional; you can add it if you like. When the skillet gets hot, add the ground sausage. Use a wooden spatula to break up the meat as it cooks. Continue to cook until the sausages are golden brown and crumbled. Remember not to stir too much, just periodically to allow the meat to brown appropriately and evenly. Once the meat is all browned and crumbly, remove from heat.
• If you used oil, drain the fat in a colander and allow the sausage to cool.
• In a mixer bowl, hand whisks the whole eggs, Italian seasoning, shredded cheese, salt, and pepper together.
• Add the egg mixture into the cooked sausage and give it a good mix.
• Pour the sausage mixture into the prepared baking dish (grease with oil or butter to prevent the meal from sticking). Bake in the preheated oven for about 45-55 minutes or until a bit firm and lightly springy to touch.
• Serve and enjoy!

📖 Variations

Like I've said before, casseroles are quite forgiving, unlike other recipes. You can toss in just about anything, and it usually turns out alright. The flavor will be different, of course, but you get to make it your own. Here's how you can give this keto breakfast casserole recipe a makeover without altering the flavor too much;

Add veggies

Feel free to incorporate veggies into the recipe. Fresh spinach, sliced mushrooms, tomatoes, bell peppers, zucchini are great additions.

Add the cream

Your breakfast casserole would still taste amazing without cream, but you can add heavy cream or whipping cream if you wish. I usually add heavy cream to my scrambled eggs for a fluffier, silkier, and extra rich texture. I bet it can work well on this low-carb egg casserole too.

Sub the mozzarella cheese:

This keto breakfast casserole can also be tasty with shredded cheddar cheese or parmesan cheese instead of mozzarella. Actually, any cheese will do but go for the ones that melt quickly. If you're sensitive to dairy or on whole30 or paleo diet, leave the cheese out. Otherwise this is keto diet friendly.

Add your favorite seasonings:

I love the herby flavor Italian seasoning brings to meals, especially this cheese casserole. But you can swap it out with any mix of herbs you have in your spice drawer. You can also try my homemade Ranch seasoning. It's a sure hit on this gluten-free breakfast casserole recipe. Garlic powder, onion powder, and smoked paprika are another great combo you can't go wrong with.

🧊 Storing and ♨️ Reheating

The best thing about this keto low-carb breakfast casserole is that it freezes well. So if you have leftovers, you can still enjoy them days or months after refrigeration/ freezing. But make sure the breakfast casserole is completely cool before refrigerating or freezing.

Fridge

For maximum flavor and freshness, refrigerate the casserole for 3-4 days. Ensure you store it in an airtight container.

To reheat microwave until hot and serve.

Freezer

This keto breakfast casserole can last up to 3 months in the freezer. You can opt to freeze it whole or divide it into smaller portions. Simply double-wrap with plastic wrap and place it in the freezer. You can cover it with aluminum foil to hold its shape.

Unthaw in your fridge the night before, and microwave until how and serve.
