Notes

  • This recipe can easily be doubled for a 9x13-inch dish.
  • To make this breakfast casserole ahead, simply make it as directed, but stop before baking. Place the prepared casserole in the fridge covered in foil overnight, then in the morning, take it out before preheating the oven. Once the oven is hot, cook as directed.
  • Store leftovers in the fridge, covered. To reheat, place a piece on a microwave-safe plate, cover with a paper towel, and microwave for about 60 seconds.
  • Use any kind of beans you have on hand. I love black beans and always keep them in my pantry, but you can use pinto or other beans if you'd like.
  • Fresh of frozen corn will also work in this recipe. Be sure to thaw and drain the corn first if you're using frozen.
  • Swap flour or grain-free tortillas for corn tortillas if you'd like. Just remember that flour tortillas are not gluten-free if that's important to you.
  • Add in any veggies you'd like, such as bell pepper or mushroom. Just sauté them the onion and garlic.
  • Feel free to add in a cooked meat of your choice, such as crumbled bacon or chorizo.
