- 1 ½ teaspoons kosher salt: Enhances all the other flavors; using kosher salt helps ensure even seasoning.
- ½ teaspoon garlic powder: A staple for that aromatic flavor; fresh minced garlic can also be used for a punchier taste.
- ¼ teaspoon onion powder: Pairs perfectly with garlic to create a rich base flavor.
- 1 (16 ounce) package uncooked rotini pasta: Its twists and curls catch the sauce beautifully—feel free to substitute with your favorite pasta shape.

How to Make Dump and Bake Meatball Casserole
- Preheat Your Oven: Start by preheating your oven to 375°F (190°C), ensuring it’s hot enough to create that perfect, bubbly top.
- Combine Ingredients in a Baking Dish: In a large baking dish, mix together the entire jar of marinara sauce, 3 cups of water, 1 tablespoon of Italian seasoning, 1 ½ teaspoons of kosher salt, ½ teaspoon of garlic powder, and ¼ teaspoon of onion powder until well blended.
- Add the Pasta: Stir in the uncooked rotini pasta, making sure it’s fully submerged in the sauce. This ensures even cooking throughout.
- Toss in the Meatballs: Gently fold in the thawed mini meatballs, distributing them evenly across the dish without breaking them up too much.
- Top with Cheese: Sprinkle 2 cups of shredded mozzarella cheese (or Italian blend) generously over the top. Feel free to add more if you’re a real cheese lover!
- Bake Until Perfect: Cover the dish with aluminum foil and bake in the oven for 30 minutes. Remove the foil and bake for an additional 15 minutes, or until the cheese is melted and bubbly, and the pasta is tender.
- Garnish and Serve: Once it’s out of the oven, let it sit for a few minutes. Then, garnish with grated Parmesan cheese and fresh herbs for a pop of flavor and color before serving.
Storing & Reheating
If you have any leftovers, you can store them at room temperature for a couple of hours. For longer storage, refrigerate them in an airtight container for up to 4 days. If you want to keep it for a more extended period, freezing is a great option—store it in a freezer-safe container for up to 3 months. To reheat, simply place the casserole in the oven at 350°F (175°C) for about 20-25 minutes, covering it with foil if necessary, until heated through. Note that the texture might change slightly in the freezer, but a sprinkle of fresh cheese before reheating can refresh its taste.
Chef’s Helpful Tips
- Avoid overcooking your pasta; since it will cook in the oven, keep it slightly firm when adding it to the dish.
- Warm up the marinara sauce slightly before mixing it with the other ingredients to help it blend better.
- Experiment with additional veggies like spinach or bell peppers for added nutrition—just chop them finely.
- If you prefer your cheese extra bubbly, broil it for a few minutes at the end, but keep an eye on it!
- This dish can be assembled ahead of time—just cover it and store it in the fridge until you’re ready to bake.
