Can I use flour tortillas instead of corn tortillas?

Yes, you can substitute flour tortillas if you prefer a softer texture. However, corn tortillas hold up better in layers and provide a more authentic flavor.

How do I make this casserole spicier?

If you love heat, add diced jalapeños, extra chili powder, or a dash of hot sauce to the beef mixture. Spicy shredded cheese blends, like pepper jack, also enhance the heat.

Can I make this ahead of time?

Absolutely! Assemble the casserole up to 24 hours in advance and store it in the refrigerator. When ready to bake, allow it to sit at room temperature for 20 minutes before placing it in the oven.

What’s the best way to freeze this casserole?

To freeze, assemble the casserole in a freezer-safe dish, cover tightly with plastic wrap and foil, and freeze for up to 3 months. When ready to eat, thaw overnight in the refrigerator and bake as directed.

Can I use ground turkey instead of beef?

Yes! Ground turkey is a great alternative if you want a leaner option. You may need to add a little extra taco seasoning since turkey has a milder flavor.

Cook Mode Prevent your screen from going dark

Instructions

1️⃣ Prepare the Beef Mixture

Cook the ground beef in a large skillet over medium heat until browned. Drain excess grease. Add taco seasoning and mix well. Stir in chili beans, Rotel, and crushed tomatoes. Simmer for 5 minutes to blend the flavors.

2️⃣ Layer the Casserole

Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish. Layer as follows:

Spread a thin layer of the beef mixture.
Place a layer of corn tortillas.
Spread half the sour cream evenly.
Sprinkle shredded cheese.
Repeat the layers, finishing with a cheese layer on top.

3️⃣ Bake to Perfection

Cover with foil and bake for 20 minutes. Remove foil and bake another 10-15 minutes, until the cheese is golden and bubbly.

Notes

💡 Use fresh cheese for better melting—pre-shredded cheese contains anti-caking agents.
⏳ Let it rest for 5-10 minutes before slicing to keep layers intact.
🔥 Spice it up by adding diced jalapeños or using pepper jack cheese.
🌱 Make it vegetarian by swapping beef for black beans and bell peppers.
