Ingredients You’ll Need

• 1 onion, diced (white or yellow, unless you’re feeling fancy)
• 2 cloves garlic, minced (or 3 if you’re brave)
• 1 bell pepper, diced (any color, but red adds sweetness)
• 1 packet taco seasoning (or DIY with chili powder, cumin, etc.)
• 1 can black beans, drained (because fiber is your friend)
• 1 can corn, drained (or fresh if you’re extra)
• 1 can diced tomatoes (fire-roasted for bonus points)
• 6-8 corn tortillas (flour works too, but corn adds texture)
• 2 cups shredded cheese (cheddar, Monterey Jack, or a mix)
• 1 cup enchilada sauce (red or green—you do you)
• Salt and pepper (because seasoning matters)
• Optional toppings: sour cream, avocado, cilantro, jalapeños

How to Make It: Step-by-Step

1. Brown the beef: In a skillet over medium heat, cook the beef until no pink remains. Drain excess fat unless you’re into that.
2. Sauté the veggies: Add onion, garlic, and bell pepper to the skillet.Cook until soft (about 5 minutes).
3. Season it up: Stir in taco seasoning, black beans, corn, and diced tomatoes. Let it simmer for 5 minutes. Taste and adjust salt/pepper.
4. Layer like a pro: In a greased baking dish, spread a thin layer of enchilada sauce.Add a layer of tortillas (tear them to fit), followed by half the beef mixture and half the cheese. Repeat.
5. Bake to perfection: Cover with foil and bake at 375°F for 20 minutes. Uncover, bake another 10 minutes until bubbly and golden.
6. Top and serve: Let it cool for 5 minutes (unless you enjoy molten cheese burns).Add toppings and dig in.

FAQs: Mexican Casserole With Beef

Can I make this ahead of time?

Absolutely. Assemble the casserole, cover, and refrigerate for up to 24 hours before baking.

Add 5-10 minutes to the baking time if it’s cold from the fridge.

Can I use flour tortillas instead of corn?

Sure, but corn tortillas hold up better against moisture. Flour tortillas can get mushy—IMO, that’s not a dealbreaker if you’re into soft textures.

What’s the best cheese for this?

A mix of cheddar and Monterey Jack melts beautifully, but any melty cheese works. FYI, pre-shredded cheese has anti-caking agents, so it might not melt as smoothly.

How do I prevent a soggy casserole?

Drain all canned ingredients well, don’t over-sauce, and bake uncovered for the last 10 minutes to crisp things up.

Can I freeze leftovers?

Yep.

Freeze in portions for up to 2 months. Thaw in the fridge overnight before reheating.
