Ingredient Highlights & Notes

The beauty of this casserole lies in its simplicity—you probably have most of these ingredients in your pantry already! The key is using quality ground beef and a good blend of cheeses for that perfect melt. Don’t skip the taco seasoning blend; it’s what gives this dish its authentic Mexican-inspired flavor that’ll have everyone asking for seconds.

Ingredients

For the Beef Layer:

  • 1½ lbs ground beef (80/20 blend works perfectly)
  • 1 medium yellow onion, diced (sweet onions work great too)
  • 3 cloves garlic, minced
  • 1 packet taco seasoning (or 2 tbsp homemade blend)
  • 1 can (14.5 oz) diced tomatoes, drained
  • 1 can (4 oz) diced green chiles (optional, for extra kick)
  • ½ cup beef broth
  • Salt and pepper to taste
  • For the Casserole Base:

  • 6-8 corn tortillas, cut into strips (flour tortillas work too)
  • 1 can (15 oz) black beans, drained and rinsed (pinto beans are delicious too)
  • 1 cup frozen corn kernels
  • 1 cup salsa (medium or mild, depending on preference)
  • For the Cheese Layer:

  • 2 cups sharp cheddar cheese, shredded (freshly grated melts better)
  • 1 cup Monterey Jack cheese, shredded
  • ½ cup Mexican blend cheese (for extra flavor depth)
  • For Topping:

  • ½ cup sour cream
  • 2 green onions, sliced thin
  • Fresh cilantro, chopped
  • Sliced jalapeños (optional)
  • Diced avocado (add after baking)
  • Equipment & Tools

  • Large skillet or sauté pan
  • 9×13 inch baking dish
  • Cutting board and sharp knife
  • Cheese grater (if using block cheese)
  • Measuring cups and spoons
  • Aluminum foil
  • Instructions & Method

    Step 1: Prep and Preheat (5 minutes)
    Preheat your oven to 375°F. Lightly grease your 9×13 inch baking dish with cooking spray or a touch of oil. This prevents sticking and makes serving so much easier!

    Step 2: Cook the Beef Mixture (12-15 minutes)
    Heat a large skillet over medium-high heat. Add the ground beef and cook, breaking it up with a wooden spoon, until it’s nicely browned—about 6-8 minutes. You’ll hear that satisfying sizzle! Add the diced onion and cook for another 3-4 minutes until softened and fragrant. Stir in the minced garlic and cook for just 30 seconds until aromatic.

    Step 3: Season and Simmer (5-7 minutes)
    Sprinkle the taco seasoning over the beef mixture and stir well to coat everything evenly. Add the drained diced tomatoes, green chiles (if using), and beef broth. Let this simmer for 5-7 minutes until the liquid reduces slightly and the flavors meld together beautifully. Season with salt and pepper to taste.

    Step 4: Layer the Casserole (5 minutes)
    Now comes the fun part—building your casserole! Spread half of the tortilla strips across the bottom of your prepared baking dish. Layer on the black beans and corn, then pour the seasoned beef mixture over everything. Add the salsa in dollops, then spread gently. Top with the remaining tortilla strips.

    Step 5: Add the Cheese (2 minutes)
    Combine all three cheeses in a bowl, then sprinkle this glorious mixture evenly over the top. Don’t be shy—this is what creates that golden, bubbly top we’re all dreaming about!

    Step 6: Bake to Perfection (25-30 minutes)
    Cover with foil and bake for 20 minutes. Remove the foil and continue baking for 5-10 minutes until the cheese is melted, bubbly, and just starting to turn golden around the edges. The aroma will be absolutely incredible!

    Step 7: Rest and Serve (5 minutes)
    Let the casserole rest for 5 minutes before serving—this helps it set up so you get clean, beautiful slices. Top with dollops of sour cream, fresh green onions, cilantro, and any other toppings your heart desires.

    Pro Tips:

  • For extra flavor, sauté the corn kernels with the onions for 2-3 minutes before adding to the casserole
  • Let the beef mixture cool slightly before assembling to prevent the cheese from melting prematurely
  • Use a mix of fresh and pre-shredded cheese for the best melt and convenience
  • Delicious Variations:

  • Chicken Version: Substitute ground chicken or turkey for a lighter option
  • Vegetarian Twist: Replace beef with seasoned lentils or extra beans and vegetables
  • Spicy Kick: Add diced jalapeños to the beef mixture and use pepper jack cheese
  • Southwest Style: Mix in some roasted bell peppers and use chipotle seasoning
  • Smart Substitutions:

  • Gluten-free: Use corn tortillas and check that your taco seasoning is gluten-free
  • Dairy-free: Swap in your favorite plant-based cheese alternatives
  • Lower sodium: Use low-sodium broth and make your own taco seasoning blend
  • Troubleshooting:

  • If your casserole seems too dry, add an extra ¼ cup of broth or salsa
  • Casserole too watery? Let the beef mixture simmer a bit longer to reduce excess liquid
  • Cheese not browning? Switch to broil for the last 2-3 minutes, watching carefully

  • Frequently Asked Questions

    Q: Can I use ground turkey instead of beef?
    A: Absolutely! Ground turkey works wonderfully in this recipe. You might want to add an extra tablespoon of oil to the pan since turkey is leaner than beef. The flavor will be slightly milder, so feel free to bump up the seasonings a bit.

    Q: What if I don’t have taco seasoning packets?
    A: No problem! Make your own blend with 1 tbsp chili powder, 1 tsp each of cumin and paprika, ½ tsp each of onion powder and garlic powder, ¼ tsp oregano, and a pinch of cayenne pepper. It tastes even better than store-bought!

    Q: Can I prep this casserole ahead for a party?
    A: Yes! This is actually one of my favorite make-ahead dishes. Assemble everything except the final cheese layer up to 24 hours in advance. Add the cheese just before baking. It’s perfect for entertaining!

    Q: Why is my casserole watery?
    A: This usually happens when the beef mixture has too much liquid. Make sure to drain your diced tomatoes well and let the beef mixture simmer until most of the liquid evaporates. Also, avoid using salsa that’s too thin or watery.

    Q: Can I freeze individual portions?
    A: Definitely! Cut the cooled casserole into individual portions, wrap each piece in plastic wrap, then place in freezer bags. They’ll keep for up to 3 months and are perfect for quick lunches or dinners.

    Q: What’s the best way to get clean slices?
    A: Let the casserole rest for at least 5 minutes after baking—this allows the layers to set up properly. Use a sharp knife and wipe it clean between cuts for the prettiest presentation.
