Mexican Breakfast Casserole is an amazing make-ahead breakfast recipe. Packed with cheesy eggs, spicy chorizo and peppers, it's a hearty, flavorful breakfast that's an easy meal for busy mornings!
Preheat oven to 375*, and prepare a 9 X 13-inch baking dish by spraying it generously, especially the bottom, with cooking spray. Of course, if you're making this the night before, you won't preheat your oven until you're ready to bake it the next morning.
Heat the olive oil in a large skillet over medium heat. Add the onion, green pepper, and garlic, and sauté for about two minutes.
Add chorizo and taco seasoning. Cook for about 5-7 minutes. Add corn, black beans, and tomatoes, and cook until heated through.
Place 12 of the tortilla quarters in the bottom of the prepared baking dish. Evenly distribute 1/3 of the meat mixture on top. Sprinkle with 1/2 cup of cheese. Repeat with tortillas, meat, and cheese for two more layers, and top with remaining tortillas.
In a large mixing bowl, beat eggs. Add milk and mix. Using a ladle, evenly distribute the egg mixture over the entire baking dish.
Cover dish with tin foil and either refrigerate overnight or bake for 30 minutes. Remove tin foil, sprinkle remaining cheese over top and bake for an additional 20-25 minutes or until a knife inserted into the middle comes out clean.
