Ingredients for Slow Cooker Meatball Pasta Casserole
• 1½ cups uncooked rotini pasta

• ¾ cup water
• 12 oz fully cooked frozen mini meatballs, thawed
• 1 cup shredded mozzarella or Italian blend cheese

Ingredient Notes
Rotini pasta
Rotini works well because the sauce clings to the spiral shape.
Frozen mini meatballs
Fully cooked frozen meatballs are convenient and work perfectly in the slow cooker.
Marinara sauce
Use your favorite jarred marinara or spaghetti sauce. Budget store brands work just as well.
Cheese
Mozzarella melts beautifully, but Italian blend cheese also works well.
How to Make Slow Cooker Meatball Pasta Casserole
- Place the meatballs, marinara sauce, and water into a small 2–3 quart slow cooker.
- Stir to combine and cook on Low for 3–4 hours until the meatballs are heated through and the sauce is hot.
- About 15 minutes before serving, cook the rotini pasta in a separate pot according to package directions. Drain well.
- Add the cooked pasta to the slow cooker and stir gently to coat the pasta with sauce.
- Sprinkle the shredded mozzarella evenly over the top.

It’s better to cook the pasta separately to prevent it from becoming mushy.

Can I make this ahead of time?
Yes. Prepare the meatballs and sauce earlier, then cook the pasta and add the cheese just before serving.
