1-First Step: Preheat your oven to 350°F and set out a baking dish (a 9×13-inch pan works great). If you’re using frozen meatballs, thaw them first so they heat evenly.

2-Second Step: Cook the pasta. Boil 16 ounces ziti, penne, or rigatoni pasta until it’s just before al dente. Then rinse the pasta with cold water to stop cooking and prevent mushy texture later.

3-Third Step: Simmer the marinara. In a large pot over medium heat, warm the 1 (24-ounce) jar marinara sauce, then add the meatballs. Simmer for 5 minutes so the flavors mingle and the sauce gets extra savory.

4-Fourth Step: Combine gently. Add the pasta into the pot with the meatballs and sauce, then stir until everything is coated. Be gentle here so pasta doesn’t break and meatballs stay intact.

5-Fifth Step: Transfer to the baking dish. Pour the mixture into your prepared baking dish and spread it out evenly. Top with 1 to 2 cups mozzarella cheese (you’ll use the full 8 ounces total depending on how thick you like the layer).

6-Final Step: Bake and finish. Bake at 350°F for 30 minutes, until the cheese melts and bubbles. If you want a lightly golden top, broil briefly for a minute or two, then garnish with 3 tablespoons fresh chopped basil and optional freshly grated Parmesan.
