Cooking Tips for Best Results
Keep the meatballs evenly sized for consistent cooking. If they’re too big, they might stay raw inside.
Use the low setting if you have time; the slow cooking makes the meatballs extra tender. Avoid lifting the lid too much, or it will slow down the cooking.
If you use thicker sauce, add a little water or broth to avoid burning. Taste and adjust seasoning near the end. You can freeze any leftovers in the sauce for an easy meal later.

Serving and Storing Slow Cooker Italian Meatballs
You can enjoy slow cooker Italian meatballs in many tasty ways, and storing them properly ensures they stay fresh and delicious. How you serve and save your meatballs can make a big difference in your meal experience.
Serving Suggestions
Serve your meatballs over cooked spaghetti or any pasta for a classic Italian dinner. They also work great in a toasted sub roll with melted mozzarella for a hearty meatball sandwich.
For a simple side, try garlic bread or roasted vegetables. You can sprinkle extra Parmesan cheese and fresh parsley on top for added flavor.
If you want to make a casserole, layer meatballs with marinara sauce and cheese, then bake until bubbly. You could also add them to salads or serve alongside polenta to change things up.
Storing and Reheating
To keep meatballs fresh, store them in an airtight container in the fridge. They will last for 3-4 days this way. If you want to keep them longer, freeze the meatballs and sauce in a freezer-safe container for up to 3 months.
When reheating, thaw frozen meatballs overnight in the fridge first. Warm them in a slow cooker on low or heat gently on the stove to avoid drying out. You can also microwave them but heat in short bursts, stirring or checking to keep them moist.
Use this method to enjoy leftovers without losing flavor or texture.
