Creating Taco Pasta Casserole is both fun and simple! Follow these steps for a delightful dish:

1. Preheat Your Oven: Begin by preheating your oven to 350°F (175°C).
2. Cook the Pasta: In a large pot, bring water to a boil and cook the elbow macaroni according to package instructions. Drain and set aside.
3. Cook the Meat: In a large skillet, cook the ground beef or turkey over medium heat until browned, about 5–7 minutes. Ensure it’s crumbled and cooked through.
4. Add Seasonings: Stir in the taco seasoning and follow the package directions for added water if needed.
5. Combine Ingredients: Add the diced tomatoes, black beans, corn, and cooked pasta to the skillet. Mix everything well to combine the flavors.
6. Prepare the Casserole Dish: In a separate bowl, mix the salsa and sour cream until smooth. Then, layer half of the pasta mixture in a greased 9×13 inch baking dish.
7. Add Cheese Layers: Sprinkle half of the cheddar and Monterey Jack cheese over the pasta mixture.
8. Layer Again: Pour the salsa and sour cream mixture over the cheese layer, then top with the remaining pasta mixture and finish with the rest of the cheese.
9. Bake: Place the casserole in the preheated oven and bake for 25–30 minutes or until the cheese is bubbly and golden.
10. Cool and Serve: Allow the casserole to cool for a few minutes before serving. Garnish with chopped green onions if desired.
