Transform your dinner routine with these succulent slow cooker meatballs. This recipe is perfect for busy days when you want a hearty, home-cooked meal without spending hours in the kitchen. The slow cooker does all the work, infusing the meatballs with rich flavors as they simmer in a delicious tomato sauce.
Most of the ingredients in this recipe are common pantry staples. However, if you don't usually keep breadcrumbs on hand, you might need to pick some up at the supermarket. They help bind the ground beef and add texture to the meatballs. Everything else, like tomato sauce, egg, salt, and black pepper, should be easy to find.

Ingredients For Slow Cooker Meatballs Recipe
Ground beef: The base of the meatballs, providing rich flavor and protein.
Breadcrumbs: Helps bind the meatballs and adds texture.
Egg: Acts as a binder to hold the meatballs together.
Salt: Enhances the overall flavor of the meatballs.
Black pepper: Adds a hint of spice and depth to the meatballs.
Tomato sauce: Coats the meatballs, infusing them with a rich, savory flavor as they cook.
Technique Tip for Making Meatballs
When forming the meatballs, make sure to keep them uniform in size to ensure even cooking. Using a small ice cream scoop or a tablespoon can help achieve this consistency. Additionally, avoid over-mixing the ground beef mixture as it can make the meatballs dense and tough. Gently mix until the ingredients are just combined.

How to Store or Freeze Your Meatballs
Allow the meatballs to cool completely before storing. This helps prevent condensation, which can lead to soggy meatballs.
For short-term storage, place the meatballs in an airtight container and refrigerate. They will stay fresh for up to 3-4 days.
If you plan to freeze the meatballs, arrange them in a single layer on a baking sheet lined with parchment paper. This prevents them from sticking together.
Once the meatballs are frozen solid, transfer them to a freezer-safe bag or container. Label with the date to keep track of freshness.
When ready to reheat, you can thaw the meatballs in the refrigerator overnight or use the defrost setting on your microwave.
Reheat the meatballs in a saucepan over medium heat, adding a bit of tomato sauce to keep them moist. Alternatively, you can reheat them in the oven at 350°F (175°C) for about 20 minutes.
For a quick meal, you can also reheat the meatballs directly from frozen. Simply add them to a simmering pot of tomato sauce and cook until heated through, about 20-25 minutes.
To maintain the best texture and flavor, avoid reheating the meatballs multiple times. Only reheat the portion you plan to eat.
How to Reheat Leftovers
Microwave: Place the meatballs in a microwave-safe dish and cover with a microwave-safe lid or plastic wrap. Heat on medium power for 2-3 minutes, stirring halfway through to ensure even heating. Check if the meatballs are heated thoroughly. If not, continue heating in 30-second intervals.
Oven: Preheat your oven to 350°F (175°C). Place the meatballs in an oven-safe dish and cover with aluminum foil to prevent drying out. Heat for about 15-20 minutes or until the meatballs are heated through. For a bit of extra flavor, you can sprinkle some grated cheese on top before reheating.
Stovetop: In a skillet, add a small amount of olive oil or tomato sauce to prevent sticking. Place the meatballs in the skillet and cover with a lid. Heat on medium-low, turning occasionally, until the meatballs are warmed through, which should take about 10-15 minutes.
Slow Cooker: If you have time, you can reheat the meatballs in the slow cooker. Place them back in the slow cooker and set it to low for 1-2 hours, or until they are heated through. This method ensures the meatballs remain tender and juicy.
Air Fryer: Preheat your air fryer to 350°F (175°C). Place the meatballs in the air fryer basket in a single layer. Heat for about 5-7 minutes, shaking the basket halfway through to ensure even heating. This method gives the meatballs a slightly crispy exterior while keeping the inside moist.
