Sausage, Potato, and Egg Casserole

Step 1
Preheat the oven to 375 degrees F (190 degrees C). Grease an 11×13-inch baking dish with cooking spray.

Step 2
Place cubed potatoes in a large microwave-safe bowl and partially cover with a lid. Microwave on high for 4 minutes. Remove from the microwave and spread on the bottom of the prepared baking dish.

Step 3
Heat a large skillet over medium-high heat. Cook and stir breakfast and chorizo sausage in the hot skillet until browned and crumbly, 5 to 7 minutes. Drain and discard grease. Add bell peppers, onion, and mushrooms. Saute until bell peppers and onion are softened, about 5 minutes. Spread mixture over the potatoes.

Step 4
Beat eggs in a bowl and add milk. Pour beaten eggs over everything in the baking dish and move around a bit with a spoon to evenly disperse. Sprinkle Cheddar cheese over top until well covered. Cover with aluminum foil.

Step 5
Bake in the preheated oven for 30 minutes. Remove foil and bake until egg is set, about 1 more hour. If cheese starts to brown too much, cover again with foil for the rest of the baking time.
