This recipe takes me straight back to the hilarious culinary divide in our family: we were the German side, and my cousin’s crew? Full-on Italian. I’m talking Sunday sauce simmering for hours, homemade pasta, and meatballs the size of softballs. Meanwhile, my sweet Mom would pull out a bag of frozen meatballs, toss them into a casserole, and proudly call it “homemade Italian!”

And you know what? We loved it. This simple, cheesy, meatball-stuffed casserole may not win any awards in Little Italy - but it wins hearts (and empty plates) every single time!
This is one of those no-fuss, crowd-pleasing dinners that comes together in about 10 minutes of prep. It uses pantry staples and a bag of frozen meatballs, and still feels like a warm hug when it hits the table! Whether it’s a crazy weeknight or you’re feeding a small crowd, this baked meatball casserole is chef’s kiss easy and comforting.
Ingredients You’ll Need:
- 1 lb penne pasta, uncooked
- 1 lb frozen meatballs, thawed
- 1 (24 oz) jar of marinara sauce
- 1 (14.5 oz) can of beef broth
- ½ tablespoon Italian seasoning
- 1 teaspoon minced garlic
- Salt and pepper to taste
- 8 oz mozzarella cheese, shredded
- 2 tablespoon fresh parsley, chopped

Supplies:
- Measuring spoons
- 9×13 inch casserole dish
- Silicone spatula or spoon
- Aluminum foil
- Cutting board + knife
How to Make This Casserole:
Preheat the oven to 425°F and grease your 9×13 inch baking dish.

In the dish, combine the uncooked pasta, thawed meatballs, marinara, beef broth, garlic, Italian seasoning, and a pinch of salt and pepper. Stir it all up like you mean it!

Cover the dish tightly with foil and bake for 30 minutes.
Remove the foil, give everything a good stir, and top with shredded mozzarella.

Pop it back in the oven (uncovered) for 10 more minutes, until the cheese is melted and bubbly.
Sprinkle with fresh chopped parsley and serve hot!

That’s it! Just dump, stir, bake, and boom - instant dinner hero.
Tara’s Tips:
- Want it saucier? Add an extra ½ cup of marinara or a splash more broth.
- Feeding picky eaters? Use smaller meatballs or slice them in half for easier bites.
- Make it ahead and refrigerate before baking - just add 10 extra minutes to the covered bake time.
- You can use frozen meatballs straight from the freezer, but thawed is best for even cooking.
