Ingredients

• 1 lb ground beef
• 1 medium yellow onion, diced
• 1 packet taco seasoning mix
• 1 can diced tomatoes with green chilies (e.g., Rotel)
• 1 can black beans, drained and rinsed
• 1 cup frozen corn, thawed
• 1 cup sour cream
• 2 cups shredded Mexican blend cheese
• 4 cups tortilla chips, slightly crushed
• 0.25 cup fresh cilantro, chopped (optional)

Directions

Step 1

Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish lightly with cooking spray or oil.

Step 2

In a large skillet over medium heat, cook the ground beef and diced onions until the beef is browned and cooked through, about 7–8 minutes. Drain any excess grease.

Step 3

Stir in the taco seasoning packet, diced tomatoes with green chilies, black beans, and thawed corn. Cook for an additional 2–3 minutes, allowing the flavors to combine.

Step 4

Layer half of the tortilla chips on the bottom of the prepared baking dish. Evenly spread half of the beef mixture over the chips. Top with half the sour cream and 1 cup of shredded cheese.

Step 5

Repeat the layering process with the remaining tortilla chips, beef mixture, sour cream, and cheese.

Step 6

Cover the casserole loosely with foil and bake in the preheated oven for 20 minutes. Remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly and golden.

Step 7

Let the casserole cool for 5 minutes before garnishing with chopped cilantro, if desired. Serve warm with additional chips, sour cream, or salsa on the side!
