Step 1: Preheat the Oven – Begin by preheating your oven to 375°F. This ensures your Loaded Cheesy Taco Casserole bakes evenly from the start.

Step 2: Cook the Ground Beef – In a large skillet, brown the ground beef over medium heat until it’s fully cooked. Drain any excess fat to keep the casserole from becoming greasy.

Step 3: Add the Seasoning – Next, stir in the taco seasoning and water. Let it cook for about five minutes, stirring occasionally, until the mixture thickens and begins to stick together. This step is key for locking in those bold taco flavors!

Step 4: Mix the Filling – In a separate large mixing bowl, combine the seasoned beef with the black beans, corn, and salsa. This hearty mixture will bring all the elements together for the casserole.

Step 5: Prepare the Tortilla Crust – Now, layer two large flour tortillas on the bottom of a greased 9×13 inch baking dish. Make sure they overlap slightly to create a solid base for your casserole.

Step 6: Layer the Filling – Spread half of your beef mixture evenly over the tortillas, then sprinkle half of the shredded cheddar and Monterey Jack cheeses on top. This layering adds depth of flavor!

Step 7: Repeat the Layers – Place another layer of tortillas atop the filling, followed by the remaining beef mixture. Finish by topping with the leftover cheese, ensuring everything is generously covered.

Step 8: Bake the Casserole – Cover the dish with foil and bake in the preheated oven for 25 minutes. After that, carefully remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly and golden brown.

Step 9: Serve & Garnish – Once baked, let the casserole cool for about five minutes. Before serving, top it generously with sour cream, sliced jalapeños, and freshly chopped cilantro for an extra burst of flavor. Slice and enjoy this Loaded Cheesy Taco Casserole!
