Ingredients
For the casserole:
- 1 pound ground beef
- 2 tablespoons taco seasoning
- 1 can (15 oz) chili beans, drained and rinsed
- 1 can (10 oz) Rotel (diced tomatoes with green chilies)
- 1 can (15 oz) crushed tomatoes
- 12-16 corn tortillas, cut into quarters
- 1 cup sour cream
- 2 cups shredded cheddar cheese
Optional add-ons:
- Sliced olives, jalapeños, or chopped cilantro for garnish
- A dollop of guacamole or salsa on the side
Tools & Equipment
- Large skillet
- 13×9-inch casserole dish
- Knife and cutting board (for cutting tortillas)
- Spoon for layering
Step-by-Step Instructions
Step 1: In a large skillet, cook the ground beef over medium heat until browned. Drain any excess grease.
Pro Tip: If you’re looking for a leaner option, feel free to swap in ground turkey or chicken.
Step 2: Add taco seasoning, chili beans, Rotel (diced tomatoes with green chilies), and crushed tomatoes to the skillet with the beef. Stir everything together and let it simmer for 5-7 minutes to blend the flavors.
Tip: You can adjust the heat level by using mild or spicy Rotel, depending on your family’s preference.
Step 3: Spray a 13×9-inch casserole dish with cooking spray. Begin by layering a few tortilla quarters on the bottom.
Step 4: Spread half of the beef mixture over the tortillas. Then, sprinkle with half of the shredded cheddar cheese. Add another layer of tortillas, followed by the rest of the beef mixture. Spread sour cream evenly over the top layer, then sprinkle with the remaining cheese.
Step 5: Place the casserole in the oven and bake at 350°F for 20 minutes, or until the cheese is melted and bubbly.
Step 6: Once it’s golden and bubbly, pull it out and serve hot! You can garnish with fresh cilantro, a dollop of sour cream, or some crispy tortilla chips on the side.
Notes & Variations
- Make it vegetarian: Swap out the ground beef for black beans or a mixture of your favorite vegetables like bell peppers and zucchini.
- Dairy-free option: Use dairy-free cheese and sour cream alternatives for a more inclusive dish.
- Add a spicy kick: Throw in some diced jalapeños or a few dashes of hot sauce to bring the heat!
- Gluten-free: Simply swap out regular tortillas for gluten-free corn tortillas.
Pro Tip: Don’t skip the sour cream on top—it adds a lovely creamy texture that balances out the spices.
Storage & Reheating
This casserole stores well in the fridge for up to 3 days. To reheat, simply cover with foil and bake at 350°F for about 15 minutes, or microwave individual portions until heated through. It also freezes well! Just wrap it tightly and store in an airtight container for up to 3 months. Thaw overnight in the fridge before reheating.
Serving and Pairing Suggestions
This Mexican casserole is a meal in itself, but it pairs wonderfully with a simple side salad, chips, or some fresh guacamole. It’s perfect for a cozy family dinner, or you can make it for a casual gathering with friends. Don’t forget to serve with a side of sour cream, salsa, or even a bit of extra cheese for that extra touch!
