Preheat your oven to 375°F (190°C) and grease a 9×13-inch baking dish with non-stick cooking spray.
Cook the pasta shells according to the package instructions until al dente. Drain and set aside.
Cooking the Ground Meat
In a large skillet, cook the ground meat over medium heat until browned and cooked through, breaking it apart with a spoon as it cooks.
Drain any excess fat from the skillet, then return the cooked meat to the pan.
Adding Flavor
Add the taco seasoning regular or hot to the cooked meat, along with 1 cup of water or milk, stirring until well combined.
Allow the mixture to simmer for 5-7 minutes, or until the liquid has reduced and the sauce has thickened slightly.
Assembling the Casserole
In the prepared baking dish, layer half of the cooked pasta shells on the bottom.
Spoon half of the meat mixture over the pasta shells, spreading it out evenly.
Pour half of the salsa over the meat layer, spreading it out evenly.
Sprinkle half of the shredded cheese over the salsa layer.
Repeat the layers with the remaining pasta shells, meat mixture, salsa, and shredded cheese.
Baking the Casserole
Cover the baking dish with aluminum foil and bake in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly.
Remove the foil and bake for an additional 5-10 minutes, or until the cheese is golden brown and the casserole is heated through.
Serving and Enjoying
Once done, remove the casserole from the oven and let it cool for a few minutes before serving.
Garnish with chopped fresh cilantro, diced avocado, and a dollop of sour cream, if desired.
Serve hot and enjoy the delicious flavors of Basic Taco Pasta Casserole!
