Serves 4
Prep Time: 15 minutes |
Cook Time: 30 minutes |
Total Time: 45 minutes
Ingredients
- 1 pound frozen cooked meatballs (about 20 to 24 small meatballs)
- 8 ounces dry penne or rigatoni pasta (about half a standard box)
- 3 cups marinara sauce (about 24 ounces)
- 2 cups shredded mozzarella cheese (about 8 ounces)
- 1/4 cup grated Parmesan cheese (about 1 ounce)
- 1 tablespoon olive oil
- 1 teaspoon dried Italian seasoning
- Salt and black pepper to taste
- 2 tablespoons chopped fresh parsley for garnish
Instructions
- Preheat the oven to 375 F and bring a large pot of salted water to a boil.
- Cook the pasta for 1 to 2 minutes less than package directions so it holds shape in the bake, drain and return to the pot, toss with olive oil and a pinch of salt.
- Stir the marinara sauce into the pasta along with the dried Italian seasoning, then gently fold in the frozen meatballs so they are evenly distributed.
- Spoon the pasta meatball mixture into a lightly oiled 9×13 inch or similar rectangular baking dish, press down slightly so it is even.
- Sprinkle the shredded mozzarella over the top, then finish with grated Parmesan and a few cracks of black pepper.
- Bake uncovered for 25 to 30 minutes until the cheese is bubbly and edges are browned and meatballs are heated through.
- Let rest for 5 minutes, sprinkle with chopped parsley, then serve.
Tips & Tricks
- Use pre cooked frozen meatballs to skip long cook times, they only need to heat through in the bake.
- Undercook pasta slightly so it does not become mushy after baking.
- Let the casserole rest five minutes after baking so the cheese sets and it slices cleaner.
- If the top browns too fast, tent with foil for the last 10 minutes of baking.
- Taste the sauce for seasoning before baking, jarred marinara can vary widely in salt and acidity.
Serving Ideas
- Serve with a green salad and simple vinaigrette for a weeknight meal.
- Offer garlic bread or toast for soaking up extra sauce at casual dinners.
- Pack portions for easy reheatable lunches for the week.
- Bring to a potluck as an easy shareable hot dish for family gatherings.
