Recipe Information
Ingredients
- 1 lb ground beef
- 1 medium yellow onion, diced
- 1 medium red bell pepper, diced
- 2 cloves minced garlic
- 1 packet taco seasoning
- 1 can (15 oz) black beans, drained and rinsed
- 1 can (10 oz) diced tomatoes with green chilies (e.g., Rotel)
- 1 cup frozen corn
- 4 large flour tortillas
- 2 cups shredded Mexican-blend cheese
- 0.5 cup sour cream
- 2 tbsp olive oil
- 0.5 tsp salt
- 0.25 tsp black pepper
- 2 tbsp chopped fresh cilantro (optional, for garnish)
- 1 tbsp sliced jalapeños (optional, for garnish)
Instructions
Preheat your oven to 375°F (190°C). Grease a 9x13-inch casserole dish and set aside.
In a large skillet, heat the olive oil over medium-high heat. Add the diced onion and red bell pepper. Sauté for 3-4 minutes until softened.
Add the minced garlic and cook for 1 minute until fragrant.
Add the ground beef to the skillet. Cook, breaking it apart with a wooden spoon, until no longer pink, about 5-7 minutes. Drain any excess fat.
Stir in the taco seasoning, salt, and black pepper. Mix well to evenly coat the beef mixture.
Add the black beans, diced tomatoes with green chilies, and frozen corn to the skillet. Stir to combine and cook for an additional 2-3 minutes. Remove from heat.
Spread a thin layer of the beef mixture on the bottom of the prepared casserole dish.
Place one tortilla on top of the beef mixture, trimming edges if necessary to fit the dish.
Spread a layer of sour cream over the tortilla. Add another layer of the beef mixture and sprinkle with shredded cheese. Repeat layering with the remaining tortillas, beef mixture, sour cream, and cheese, finishing with a cheese layer on top.
Cover the dish with aluminum foil and bake for 20 minutes.
Remove the foil and bake for an additional 10-15 minutes, or until the cheese is melted and bubbly.
Let the casserole rest for 5 minutes before serving.
Garnish with chopped fresh cilantro and sliced jalapeños, if desired. Serve warm and enjoy!
