Ingredients

  

• 1 tablespoon olive oil
• 1 medium yellow onion, diced
• 1 red bell pepper, diced (optional)
• 2 cloves garlic, minced
• 1.25 pounds ground beef (or turkey, chicken, or plant-based crumbles)
• 2 tablespoons taco seasoning (store-bought or homemade)
• 1/2 teaspoon kosher salt, plus more to taste
• 1/4 teaspoon black pepper
• 1 cup salsa (mild, medium, or hot)
• 1 (15-ounce) can black beans, drained and rinsed
• 1 cup corn kernels (frozen or canned and drained)
• 1 (10-ounce) can diced tomatoes with green chiles, drained
• 8–10 small corn tortillas, cut into halves or quarters
• 2 cups shredded Mexican blend or cheddar cheese
• 1/4 cup chopped cilantro (optional)
• For serving: sour cream or Greek yogurt, diced avocado, shredded lettuce, sliced green onions, lime wedges

Method

 

1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
2. Warm the olive oil in a large skillet over medium heat. Add the onion and bell pepper.

   Cook for 5–6 minutes until softened. Stir in the garlic and cook 30 seconds more.

3. Add the ground beef. Cook, breaking it up with a spoon, until browned and no longer pink, about 6–8 minutes.

   Drain excess fat if needed.

4. Season the meat with taco seasoning, salt, and pepper. Stir in the salsa, black beans, corn, and diced tomatoes with green chiles. Simmer 2–3 minutes to thicken slightly.

   Taste and adjust seasoning.

5. Layer the casserole: Arrange a single layer of tortilla pieces on the bottom of the baking dish. Spoon half of the meat mixture over the tortillas. Sprinkle with 1 cup of cheese.
6. Repeat with another tortilla layer, the remaining meat mixture, and the remaining 1 cup cheese.
7. Cover loosely with foil and bake for 15 minutes.

   Remove foil and bake another 8–10 minutes, until the cheese is melted and bubbly around the edges.

8. Let it rest for 10 minutes so it sets and slices cleanly. Top with cilantro and your favorite garnishes. Slice and serve.

Keeping It Fresh

• Fridge: Store leftovers in an airtight container for up to 4 days.

  Reheat in the oven at 325°F until warm or microwave in short bursts.

• Freezer: Wrap the baked casserole tightly or portion into freezer-safe containers. Freeze up to 3 months. Thaw overnight in the fridge before reheating.
• Make-ahead: Assemble up to 24 hours ahead, cover, and refrigerate.

  Add 5–10 minutes to the baking time if starting from cold.

• Keep toppings separate: Store lettuce, avocado, and sour cream in separate containers so they stay fresh and crisp.

Why This is Good for You

• Protein-rich: Ground beef or turkey provides protein to keep you full. Swap in beans or lentils for a plant-based boost.
• Fiber from beans and corn: Helps with digestion and steady energy.
• Customizable fats: Use lean meat and moderate cheese, or try part-skim cheese to lighten it up without losing flavor.
• Veggie-friendly: Onions, peppers, tomatoes, and optional toppings add vitamins and antioxidants.

What Not to Do

• Don’t skip the rest time: Cutting too soon makes it messy and watery. Ten minutes helps it set.
• Don’t over-sauce: Too much salsa or liquid leads to soggy tortillas.

  Drain canned tomatoes well.

• Don’t under-season: Taste the filling before layering. A pinch more salt or seasoning can make a big difference.
• Don’t overload with cheese: It’s tempting, but too much can make the casserole greasy. Stick to the measured amount, then add a sprinkle after baking if needed.
• Don’t use raw tortillas straight from the package if they’re stiff: Warm them briefly so they layer and bake nicely.

Alternatives

• Protein swaps: Ground turkey, shredded rotisserie chicken, chorizo, or crumbled tofu all work well.
• Veggie-forward: Add sautéed zucchini, mushrooms, or spinach to the filling for extra bulk and nutrients.
• Tortilla options: Use flour tortillas, crushed tortilla chips for a crunchy top layer, or even cooked rice for a “taco rice bake.”
• Dairy-free: Use dairy-free shredded cheese and a dairy-free yogurt for topping.
• Low-carb: Swap tortillas for thin layers of roasted zucchini or cauliflower rice (drain well to avoid excess moisture).
• Spice level: Choose mild or hot salsa, add jalapeños, or stir in chipotle powder for smoky heat.

FAQ

Can I use store-bought taco seasoning?

Yes.

It’s convenient and works great. If you want to make your own, mix chili powder, cumin, paprika, garlic powder, onion powder, oregano, salt, and a pinch of cayenne.

How do I keep the tortillas from getting soggy?

Drain any canned ingredients well, don’t add extra liquid beyond the salsa, and let the casserole rest before slicing. Using slightly toasted tortillas can also help.

What size pan should I use?

A standard 9×13-inch baking dish is ideal.

If you use a smaller pan, the layers will be thicker and may need a few extra minutes in the oven.

Can I make this vegetarian?

Absolutely. Skip the meat and use 2 cans of beans (black, pinto, or a mix) or add crumbled tofu or lentils for extra protein.

How do I reheat without drying it out?

Cover the casserole with foil and reheat at 325°F until warmed through. If needed, add a tablespoon of water around the edges to create a little steam.

What are the best toppings?

Sour cream or Greek yogurt, avocado, shredded lettuce, chopped tomatoes, green onions, cilantro, sliced jalapeños, and a squeeze of lime all add freshness and texture.

Can I assemble and freeze it unbaked?

Yes.

Assemble without baking, wrap tightly, and freeze. Thaw in the fridge overnight, then bake covered for 20 minutes and uncovered for 10–15 minutes more, until hot and bubbly.
