🛒 Ingredients
- 1 lb ground beef
- 1 small onion, diced
- 1 packet taco seasoning
- 1 (15 oz) can black beans, drained and rinsed
- 1 (15 oz) can corn, drained
- 1 (10 oz) can Rotel (diced tomatoes with green chilies)
- 1 cup salsa
- 2 cups shredded cheddar or Mexican blend cheese
- 1 bag tortilla chips, slightly crushed
- Optional toppings: sour cream, green onions, jalapeños, avocado
🔄 Ingredient Swaps & Tips
- Meat Swap: Use ground turkey or shredded chicken instead of beef.
- Make it Veggie: Skip the meat and double the beans or add sautéed zucchini and bell peppers.
- Cheese Choices: Try pepper jack for extra heat or a blend of cheddar and mozzarella.
- Low-Carb Option: Replace chips with sautéed cauliflower or use low-carb tortillas cut into strips.
👨🍳 How to Make It
- Preheat oven to 350°F (175°C). Lightly grease a 9×13″ baking dish.
- In a large skillet, cook ground beef and diced onion over medium heat until browned. Drain excess grease.
- Stir in taco seasoning, black beans, corn, Rotel, and salsa. Simmer for 5–7 minutes to meld flavors.
- In the prepared baking dish, layer half the crushed tortilla chips, then half the meat mixture, then half the shredded cheese.
- Repeat the layers: chips, meat, cheese.
- Cover with foil and bake for 20 minutes. Then uncover and bake for 10 more minutes, until bubbly and golden.
- Let cool for 5–10 minutes. Top with sour cream, green onions, or jalapeños as desired. Serve warm.
💡 Tips for Success
- Use a sturdy chip like restaurant-style or lightly crush to avoid soggy layers.
- Don’t overbake—just enough to melt the cheese and toast the top layer of chips.
- Want extra crunch? Add a handful of chips on top right before serving.
- This dish is perfect for make-ahead—assemble the day before and bake when ready.
