Ingredients
- 1 lb lean ground beef (93% lean or higher)
- 1 tsp olive oil
- 1 small onion, finely chopped
- 1 packet taco seasoning (or homemade seasoning blend)
- 1 (14.5 oz) can diced tomatoes, drained
- 1 (15 oz) can black beans, drained and rinsed
- 1 cup corn kernels (fresh or frozen)
- 1 cup reduced-fat shredded cheddar cheese
- ½ cup reduced-fat sour cream (or plain Greek yogurt)
- 6 small whole wheat tortillas, cut into strips or torn into pieces
- Fresh cilantro, for garnish (optional)
- 1 small jalapeño, sliced (optional)
Instructions
Preheat the Oven:
Set your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
Cook the Beef:
In a large skillet, heat the olive oil over medium heat. Add the chopped onion and cook until softened, about 3 minutes. Add the ground beef and taco seasoning, cooking until browned and fully cooked. Stir in the diced tomatoes, black beans, and corn, mixing until everything is well combined. Remove from heat.
Layer the Casserole:
Place a layer of tortilla strips at the bottom of the prepared baking dish. Spoon half of the beef mixture over the tortillas, followed by a layer of shredded cheese. Repeat with another layer of tortilla strips, the remaining beef mixture, and the remaining cheese.
Bake:
Cover the dish with aluminum foil and bake for 20 minutes. Remove the foil and bake for an additional 5–10 minutes, or until the cheese is melted and bubbly.
Serve:
Once baked, remove from the oven and let cool slightly. Garnish with fresh cilantro and jalapeño slices, if desired. Serve with a dollop of sour cream or Greek yogurt on top.
