Ingredients

• 1 (16 ounce) package uncooked rotini pasta

• 1 (24 or 25 ounce) jar marinara sauce

• 3 cups water

• 1 (14 ounce) package fully-cooked miniature (cocktail-size) meatballs (if using frozen meatballs, make sure they are completely thawed before using)

• Optional garnish: Parmesan cheese; fresh chopped herbs such as basil, oregano, or parsley

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Directions

1. Preheat oven to 425°F.

2. In a 9 x 13-inch baking dish, combine the uncooked pasta, marinara sauce, water, and meatballs. Stir to combine and season with salt to taste.

3. Cover tightly with aluminum foil and bake for 35 minutes.

4. Uncover the casserole and stir. Check the pasta for doneness—it should be al dente, or just about tender. If it’s still too firm, cover the dish and return it to the oven until the pasta reaches your desired texture.

5. Once the pasta is done, sprinkle shredded mozzarella (or Italian blend cheese) on top.

6. Return the casserole to the oven and bake uncovered for 5–10 more minutes, or until the cheese is melted and bubbly.

7. Garnish with optional toppings like freshly grated Parmesan cheese and chopped herbs such as basil, oregano, or parsley, if desired.

8. Serve hot and enjoy!
