If you want, you can absolutely make and cook the casserole overnight on the same day! Preheat the oven while you prepare the other ingredients and place the casserole directly into the oven.

I wouldn’t prepare it more than 24 hours in advance. Be sure to store the uncooked casserole in the refrigerator, tightly covered with plastic wrap, until you’re ready to cook it.

  • This recipe is delicious with other types of spicy sausage too!
  • If you can’t find chorizo, hot Italian sausage crumbs make a great substitution.
  • For a vegetarian breakfast casserole, feel free to replace the chorizo ​​with another can of black beans or a meatless sausage alternative!
  • There are several soy chorizo ​​(“soyrizo”) products available at vegetarian grocery stores that taste great in this casserole, too.

Prevents the screen from going dark


  • Preheat oven to 375* and prepare a 9 X 13-inch baking pan by spraying it generously, especially the bottom, with cooking spray. Of course, if you make it the night before, you won’t preheat the 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 tortilla quarters in the bottom of the prepared baking dish. Spread 1/3 of the meat mixture evenly over the top. Sprinkle with 1/2 cup cheese. Repeat with tortillas, meat and cheese for two more layers and top with remaining tortillas.

  • In a large bowl, whisk the eggs. Add the milk and mix. Using a ladle, spread the egg mixture evenly over the entire baking sheet.

  • Cover the dish with foil and refrigerate overnight or bake in the oven for 30 minutes. Remove the foil, sprinkle the remaining cheese on top and bake for another 20 to 25 minutes or until a knife inserted into the center comes out clean.

  • Serve with sliced ​​avocado, salsa and sour cream.
