How to Bake a Savory Keto Breakfast Dish

Step 1: Warm Up the Oven

Crank your oven to a toasty 375F (190C). Grab a 9×13-inch baking dish and give it a light coating of cooking spray or butter to prevent sticking.

Step 2: Sizzle the Sausage

Fire up a large skillet over medium heat. Toss in the breakfast sausage and cook until it’s beautifully browned and completely done. Drain away any extra grease and set the sausage aside.

Step 3: Whip Up the Egg Blend

• Heavy cream
• Garlic powder
• Onion powder
• Salt
• Pepper

Whisk everything together until it’s smooth and uniform.

Step 4: Layer the Casserole Base

• Diced bell peppers
• Spinach
• Shredded cheddar cheese

Step 5: Pour and Top

Gently pour the egg mixture over all the ingredients in the dish. Finish by scattering mozzarella cheese on top.

Step 6: Bake to Perfection

Slide the dish into the preheated oven and bake for 30-35 minutes. You’re looking for set eggs and a golden-brown top.

Step 7: Rest and Serve

Let the casserole cool for 5-10 minutes. This helps it set and makes slicing a breeze. Cut into portions and enjoy your keto-friendly breakfast!
