Cauliflower Rice Breakfast Casserole

Step 1
Preheat the oven to 350 degrees F (175 degrees C). Grease a 9×13-inch casserole dish with cooking spray or butter.

Step 2
Heat a large skillet over medium-high heat. Cook and stir sausage in the hot skillet until browned and crumbly, 5 to 7 minutes. Reserve grease in the pan; place sausage into the prepared dish.

Step 3
Cook and stir cauliflower rice in the bacon grease over medium heat, actively stirring, until most of the moisture has been removed, 3 to 4 minutes. Place cauliflower in the casserole dish; mix in bell pepper and onion.

Step 4
Whisk eggs in a bowl with milk, 1/4 cup Cheddar cheese, salt, and pepper. Pour egg mixture over ingredients in the casserole dish; do not mix.

Step 5
Bake in the preheated oven until a knife inserted into the center comes out clean, about 30 minutes. Add remaining cheese on top and continue to bake until melted, 3 to 4 minutes.
