What’s in This Flavor Bomb?

We’re talking big flavor with minimal effort. Picture this: well-seasoned ground beef, smoky spices, sweet bursts of corn, creamy black beans, and a generous sprinkle of cheese in every bite.

The whole thing is stacked up between layers of tortillas that soak up all the goodness while still holding their own. Each bite is a perfect balance of tender, cheesy, savory, and just a little bit spicy.

It’s got crunch, creaminess, and just the right amount of heat. And it’s incredibly versatile—you can spice it up, tone it down, make it vegetarian, or toss in whatever you have in your fridge that needs using up.

Ingredients:

• 1 lb ground beef
• 1 small onion, diced
• 2 cloves garlic, minced
• 1 (1 oz) packet taco seasoning (or your own mix of chili powder, cumin, paprika, and oregano)
• 1 (15 oz) can black beans, drained and rinsed
• 1 cup corn (frozen, canned, or fresh off the cob)
• 1 (10 oz) can diced tomatoes with green chiles (like Rotel)
• 2 cups shredded Mexican blend cheese (or cheddar, Monterey Jack, or whatever you love)
• 8 small flour or corn tortillas (cut in halves or quarters for easy layering)
• Salt and pepper, to taste
• Optional toppings: sour cream, guacamole, chopped cilantro, sliced jalapeños, hot sauce

How to Make It:

1. Brown the beef.
   Start by heating a large skillet over medium heat. Add the ground beef and cook until it’s browned and crumbly. Add in the diced onion and garlic, and sauté for another few minutes until everything is golden and aromatic. Drain any excess fat if needed.
2. Add the flavor.
   Sprinkle in the taco seasoning and a splash of water (about 1/4 cup) to help the spices coat the meat. Stir well, then toss in the black beans, corn, and diced tomatoes with green chiles. Let the whole mixture simmer for 5–7 minutes so the flavors can really get to know each other.
3. Start layering.
   Preheat your oven to 375°F (190°C). Grab a greased 9×13-inch baking dish and start building your masterpiece. Begin with a layer of tortillas, then spoon on some of the beef mixture, then sprinkle with cheese. Keep going—tortillas, beef, cheese—until the dish is full and your ingredients are used up. Be sure to finish with a healthy layer of cheese on top.
4. Bake it up.
   Pop the dish into the oven and bake uncovered for 20 to 25 minutes, or until the cheese is bubbly and golden and the edges look beautifully crispy.
5. Cool and serve.
   Let the casserole rest for about 10 minutes before cutting into it. This helps it set and makes serving way easier (plus it won’t burn your mouth).

What to Serve It With

While this casserole is plenty satisfying on its own, a few simple sides can take it to the next level. A scoop of guacamole, a dollop of sour cream, or a sprinkle of chopped cilantro adds a burst of freshness. If you’re looking to round it out, try it with Spanish rice, a simple green salad, or even a side of tortilla chips and salsa.

Feeling spicy? A drizzle of hot sauce or some fresh jalapeños will wake things up in the best way.
