A simple dump-and-bake dinner that delivers big comfort with very little effort. Uncooked pasta bakes right in the sauce with juicy meatballs, soaking up all those rich flavors, then gets finished with a generous layer of melty mozzarella. It’s hearty, cozy, and on the table in about 45 minutes. Perfect for busy weeknights or when you just want something easy and satisfying.
Preheat and Prepare the Baking Dish: Start by heating your oven to 425°F. Lightly spray a 9×13-inch baking dish with cooking spray to prevent sticking.
Assemble the Casserole: Place the uncooked rotini pasta into the prepared baking dish. Pour in the water and pasta sauce, then add the thawed meatballs and sprinkle in the kosher salt. Gently mix everything together to ensure even distribution. Cover the dish securely with aluminum foil.
Bake the Casserole: Transfer the baking dish to the preheated oven and bake for 35 minutes. About halfway through the baking time, remove the dish and give everything a good stir to promote even cooking.
Add the Cheese and Finish Baking: After the initial baking period, remove the foil and give the pasta another stir. Sprinkle the shredded mozzarella cheese evenly over the top of the casserole. Return the dish to the oven and bake uncovered for an additional 5–8 minutes, or until the cheese is melted and bubbly.
Serve: Once the cheese is fully melted, remove the casserole from the oven. For an extra touch of flavor, garnish with grated Parmesan cheese or freshly chopped parsley before serving. Enjoy your delicious Dump and Bake Meatball Casserole!
