Step-by-Step Instructions

1. Preheat the Oven
   Preheat your oven to 425°F (220°C). This ensures even cooking from the start.
2. Combine Ingredients
   In a 9×13-inch baking dish, add:

3. Cover and Bake
   Cover the dish tightly with aluminum foil. Bake for 35 minutes.
4. Check and Stir
   Remove the foil and stir the casserole thoroughly. Check the pasta for doneness—it should be tender but not mushy. If needed, return to the oven covered for a few more minutes.
5. Add Cheese
   Sprinkle 2 cups shredded mozzarella evenly over the top.
6. Final Bake
   Return the dish to the oven uncovered for 5–10 minutes, or until the cheese is fully melted and bubbly.
