Five-Ingredient Mexican Casserole


Did your mom make Mexican Casserole for you growing up? My mom did and we ABSOLUTELY LOVED IT! This Mexican Casserole is loaded with refried beans, tortillas, salsa, and cheese and is layered like lasagna. This meatless meal is satisfying and filling and is so delicious.

How to Make Five-Ingredient Mexican Casserole

Make this Mexican Casserole with me!

First, you’ll start by softening the onion in a little oil in a skillet. Next, stir in the refried beans.

To a new large skillet (I know, I know, another dish to clean. But just trust the process!) add 2 tablespoons of olive oil over medium heat. Fry the tortillas one at a time in the oil until the get a little crispy. This will help the tortillas to not get soggy when layered with the beans and salsa.

Start the layering process in a 9″ round greased baking dish by placing a tortilla in the bottom of the pan. Spread about 1/3 of the bean mixture across the tortilla, then top with salsa and cheese. Repeat until all of the ingredients are gone.

Bake at 375 F for just 20 minutes, or until everything is warmed through and the cheese is melted. Serve and top with your desired toppings.

Mexican Casserole Toppings

This casserole is great as is, but you can add some toppings at the end to freshen it up a bit or add a little something extra. You can add something fresh and a little crunchy like shredded lettuce, or diced tomatoes or bell peppers. If you want another creamy topping, add guacamole and sour cream. If you like heat, add some more spicy salsa or hot sauce.

Cooking time




  • 3 tbsp 3 olive oil, divided

  • 1 1 yellow onion, diced

  • 16 oz 16 can refried beans

  • 5-6 5-6 flour tortillas

  • 1 1/2 cups 1 1/2 salsa

  • 1 1/2 cups 1 1/2 Mexican style cheese


  • Preheat oven to 375 degrees F.
  • To a skillet over medium heat, add 1 tbsp of oil. Once hot, add in the onion and sauté for 3 to 5 minutes or until it starts to get soft. Stir in the refried beans. To a new large skillet add 2 tablespoons of olive oil over medium heat. Once hot, add each tortilla, one at a time, and cook for 1-2 minutes on each side to crisp the tortillas up. This will help the tortillas to not get soggy in the oven.
  • Spray a 9-inch pie dish with nonstick spray.
  • Place one tortilla down on the pie dish and spread about 1/3 of the refried bean mixture. Then spread some salsa and cheese over the top. Repeat until the ingredients are gone.
  • Bake for 20 minutes and top with your favorite taco toppings.
