Description

This slow cooker meatball casserole is a cozy, hearty dinner that’s super easy to throw together. Juicy meatballs are simmered in marinara sauce with tender pasta and gooey melted cheese—perfect for busy weeknights or when you want something comforting with minimal effort.

Ingredients

  • 1 (28 oz) bag frozen meatballs (about 32 meatballs)

  • 1 (24 oz) jar marinara sauce

  • 1 cup water or beef broth

  • 2 cups uncooked rotini or penne pasta

  • 1 1/2 cups shredded mozzarella cheese

  • 1/4 cup grated Parmesan cheese

  • 1 teaspoon Italian seasoning

  • 1/2 teaspoon garlic powder

  • Salt and pepper, to taste

  • Fresh parsley (optional, for garnish)

Instructions

  • Spray the inside of your slow cooker with nonstick cooking spray.

  • Add frozen meatballs, marinara sauce, and water or broth. Stir to combine.

  • Cover and cook on LOW for 4 hours.

  • Stir in the uncooked pasta. Make sure the pasta is fully covered in sauce.

  • Cover again and cook on HIGH for 30–40 minutes, or until pasta is tender.

  • Sprinkle mozzarella and Parmesan cheese over the top.

  • Cover and cook for another 10–15 minutes, until cheese is melted and bubbly.

  • Season with salt and pepper to taste. Garnish with fresh parsley, if using.

 

  • Serve warm and enjoy!

Notes

  • You can use homemade meatballs if you prefer—just make sure they’re cooked before adding.

  • Use any short pasta like rotini, penne, or ziti.

  • Add some red pepper flakes if you like a little heat.

 

  • Don’t skip the water or broth—it helps cook the pasta evenly.
