A delightful twist on the classic Tex-Mex lasagna, this casserole is packed with vibrant flavors and is perfect for a family dinner.
Preheat your oven to 350°F (175°C).
Preheating ensures even cooking and the right texture for the casserole.
In a large skillet, cook the ground beef over medium heat until browned. Drain any excess fat.
Use a wooden spoon to break up the beef into small pieces for even cooking.
Add the black beans, corn, taco seasoning, and 3/4 cup of tomato sauce to the skillet. Stir well to combine.
Mix thoroughly to ensure the seasoning is evenly distributed.
In a small bowl, combine the salsa with the remaining tomato sauce.
This mixture will add a tangy and spicy layer to the casserole.
Spread a thin layer of the salsa mixture on the bottom of a baking dish. Layer with three lasagna noodles, half of the beef mixture, a third of the salsa mixture, and a third of the cheese. Repeat the layers, ending with noodles, salsa mixture, and cheese.
Press down gently on each layer to compact the casserole for even cooking.
Cover the dish with aluminum foil and bake for 45 minutes. Remove the foil and bake for an additional 5 minutes to melt the cheese.
Let the casserole rest for 10 minutes after baking to make slicing easier.
Garnish with sour cream, diced avocado, and chopped green onions before serving.
Serve with a side of tortilla chips or a fresh salad for a complete meal.
