A simple and savory 5-ingredient Mexican casserole featuring layers of refried beans, sautéed onions, salsa, flour tortillas, and melted Cheddar or Colby Jack cheese. This easy-to-make dish comes together quickly for a delicious dinner pie with classic Mexican flavors.

Ingredients

Ingredients

  • 1 (16 ounce) can refried beans
  • ¾ onion, diced
  • 5 (10 inch) flour tortillas
  • 1 cup salsa
  • 2 cups shredded Cheddar or Colby Jack cheese

Instructions

  1. Prepare Ingredients: Gather all the ingredients to ensure everything is ready. Preheat your oven to 375 degrees F (190 degrees C) and spray a 9-inch pie pan with non-stick cooking spray to prevent sticking.
  2. Sauté Beans and Onions: In a saucepan over medium-high heat, cook the refried beans with the diced onions for about 5 minutes until the onions soften and the mixture is well combined and heated through.
  3. Assemble Layers: Place one tortilla in the bottom of the prepared pie pan. Spread approximately 1/3 cup of the bean and onion mixture evenly over the tortilla, followed by a few tablespoons of salsa. Add a second tortilla on top, then more of the bean mixture, and top with a generous handful of shredded cheese. Continue layering until all tortillas and fillings are used, ensuring the topmost layer has plenty of salsa and cheese.
  4. Bake the Casserole: Place the assembled casserole in the preheated oven and bake for 15 to 20 minutes, or until the cheese is fully melted and bubbly.
  5. Serve: Remove from the oven and allow to cool slightly before slicing. Serve warm as a hearty and flavorful dinner option.

Notes

  • Use either Cheddar or Colby Jack cheese based on your preference for a milder or sharper flavor.
  • For a spicier dish, use a hot salsa instead of mild salsa.
  • You can add additional layers or ingredients such as cooked ground beef or vegetables for variety.
  • If preferred, substitute flour tortillas with corn tortillas; however, texture and flavor will vary.
  • Leftovers can be refrigerated for up to 3 days and reheated in the oven or microwave.
