Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 50 minutes
• Total Time: 1 hour 10 minutes
• Servings: 4-6
• Yield: 1 casserole
• Dietary Type: Adaptable

Ingredients

• 1 lb ground beef
• ½ cup diced onion
• 1 (1 1/4 ounce) package taco seasoning mix
• 2 cups cheddar cheese, shredded
• 1 (16 ounce) can refried beans
• 1 cup cooked rice
• ½ (12 ounce) can Mexican-style corn, drained
• 4 large flour tortillas
• 8 ounces thick chunky salsa (your choice mild or hot)
• Optional toppings: sour cream, diced white onion, shredded lettuce

Equipment Needed

• Springform cake pan or casserole dish
• Large skillet
• Cooking spray
• Measuring cups and spoons
• Aluminum foil

Instructions

1. Begin by preheating your oven to 350 degrees F (175 degrees C). This ensures even cooking throughout the casserole.
2. Lightly coat a springform cake pan or casserole dish with cooking spray. This will prevent sticking and make serving much easier.
3. In a large skillet over medium heat, brown the ground beef and diced onion. Cook until the beef is no longer pink and the onion is softened.
4. Drain off any excess grease from the skillet. This step is crucial for preventing a greasy final product.
5. Add the taco seasoning mix to the cooked ground beef and onion. Cook according to the package directions, usually involving adding water and simmering for a few minutes to allow the flavors to meld.
6. Gently heat the refried beans in a microwave-safe bowl or saucepan. Warming them up makes them easier to spread evenly across the tortillas.
7. Now, begin assembling the casserole. Place one flour tortilla in the bottom of the prepared baking dish.
8. Spread 1/3 of the heated refried beans evenly over the tortilla.
9. Top the beans with 1/3 of the seasoned ground beef mixture.
10. Sprinkle a generous amount of cheddar cheese over the meat.
11. Add the second flour tortilla to the dish, layering it on top of the cheese.
12. Spread 1/2 of the cooked rice over the tortilla.
13. Next, spread 1/2 of the chunky salsa over the rice.
14. Sprinkle 1/2 of the drained Mexican-style corn over the salsa.
15. Add another layer of cheddar cheese.
16. Add the third flour tortilla to the dish.
17. Spread another 1/3 of the refried beans over the tortilla, followed by 1/3 of the ground beef mixture, and a sprinkle of cheddar cheese.
18. Top with the final flour tortilla.
19. Layer the remaining refried beans, ground beef, Mexican-style corn, cooked rice, chunky salsa, and cheddar cheese on top.
20. Cover the baking dish tightly with aluminum foil. This prevents the top from burning and helps the casserole cook evenly.
21. Bake, covered with foil, in the preheated oven for about 40 minutes.
22. Remove the foil and bake for an additional 10-15 minutes, or until the cheese is melted and bubbly and the casserole is heated through.
23. Remove the casserole from the oven and let it sit for at least 5 minutes before cutting. This allows the layers to set slightly, making it easier to slice and serve.
24. After baking, top with sour cream, diced white onion, and shredded lettuce, if desired.

Expert Tips & Tricks

• For an extra layer of flavor, consider adding a thin layer of guacamole between the tortillas.
• If you’re short on time, pre-cooked rice from the store works perfectly.
• Don’t overbake the casserole. Overbaking can dry out the tortillas and make the cheese tough.
• Feel free to adjust the amount of taco seasoning to your liking. If you prefer a spicier casserole, add a pinch of cayenne pepper to the beef mixture.
• To prevent the bottom tortilla from becoming soggy, you can lightly toast it in a dry skillet before layering.
• If using a deep dish, consider adding an extra tortilla layer in the middle to hold the filling better.
• To get a really crispy cheese topping, broil the casserole for the last minute or two of baking, keeping a close eye on it to prevent burning.

Serving & Storage Suggestions

Serve the Mexican Tortilla Casserole warm, directly from the baking dish or sliced into wedges. It’s delicious on its own or accompanied by a side of guacamole, pico de gallo, or a dollop of sour cream.

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, microwave individual portions until heated through, or bake the entire casserole in a preheated oven at 350 degrees F (175 degrees C) until warmed.

For longer storage, the casserole can be frozen for up to 2-3 months. Wrap it tightly in plastic wrap and then in foil to prevent freezer burn. Thaw completely in the refrigerator before reheating.
