Ingredients For Slow Cooker Meatballs Recipe
Ground beef: The main protein for the meatballs, providing a rich and savory flavor.
Breadcrumbs: Helps to bind the meatballs together and adds a bit of texture.
Beaten egg: Acts as a binder to hold the meatball mixture together.
Garlic powder: Adds a subtle garlic flavor without the need for fresh garlic.
Onion powder: Provides a mild onion flavor to the meatballs.
Salt: Enhances the overall flavor of the meatballs.
Black pepper: Adds a touch of heat and depth to the flavor profile.
Marinara sauce: A tomato-based sauce that coats the meatballs and infuses them with flavor during the slow cooking process.

Alternative Ingredients
ground beef - Substitute with ground turkey: Ground turkey is a leaner option and can provide a similar texture and flavor profile.
breadcrumbs - Substitute with oatmeal: Oatmeal can act as a binding agent and adds a slightly different texture but still holds the meatballs together well.
beaten egg - Substitute with flaxseed meal and water: Mix 1 tablespoon of flaxseed meal with 3 tablespoons of water to replace the egg; this is a good vegan alternative that helps bind the ingredients.
garlic powder - Substitute with minced garlic: Fresh minced garlic provides a more robust flavor and can be used in equal amounts.
onion powder - Substitute with finely chopped onions: Fresh onions offer a more intense flavor and moisture, enhancing the overall taste.
salt - Substitute with soy sauce: Soy sauce can add a similar level of saltiness along with a bit of umami flavor.
black pepper - Substitute with white pepper: White pepper has a slightly different flavor but can provide the same level of heat and spice.
marinara sauce - Substitute with crushed tomatoes and Italian seasoning: Crushed tomatoes mixed with Italian seasoning can mimic the flavor of marinara sauce and can be adjusted to taste.

How To Store / Freeze Your Meatballs
- Allow the meatballs to cool completely before storing. This helps prevent condensation, which can lead to soggy meatballs.
- Transfer the cooled meatballs and marinara sauce into an airtight container. Ensure the container is sealed tightly to maintain freshness.
- Store the container in the refrigerator if you plan to consume the meatballs within 3-4 days. This keeps them fresh and ready for a quick meal.
- For longer storage, place the meatballs and marinara sauce in a freezer-safe container or a heavy-duty freezer bag. Label the container with the date to keep track of its freshness.
- When freezing, ensure the meatballs are arranged in a single layer to prevent them from sticking together. This makes it easier to thaw only the amount you need.
- To reheat refrigerated meatballs, place them in a saucepan over medium heat until heated through, or microwave them in a microwave-safe dish, stirring occasionally.
- For frozen meatballs, thaw them in the refrigerator overnight before reheating. Alternatively, you can reheat them directly from frozen by simmering them in a saucepan with additional marinara sauce until fully heated.
- If you prefer a quicker method, use a microwave to defrost the meatballs on the defrost setting, then heat them thoroughly before serving.
- Enjoy your meatballs over pasta, in a sub roll, or as a delicious appetizer with toothpicks.
How To Reheat Leftovers
Oven Method: Preheat your oven to 350°F (175°C). Place the meatballs in a baking dish and cover with foil to prevent them from drying out. Heat for about 15-20 minutes or until they are warmed through. This method helps maintain the meatballs' texture and flavor.
Stovetop Method: Add a splash of marinara sauce to a skillet and heat over medium-low. Place the meatballs in the skillet, cover, and cook for about 10-15 minutes, stirring occasionally. This method ensures the meatballs stay moist and absorb more flavor from the sauce.
Microwave Method: Place the meatballs in a microwave-safe dish and cover with a microwave-safe lid or plastic wrap, leaving a small vent. Heat on medium power for 2-3 minutes, stirring halfway through. This is the quickest method but may result in slightly drier meatballs.
Slow Cooker Method: If you have more time, place the meatballs back in the slow cooker with a bit of marinara sauce. Set to low and heat for 1-2 hours. This method is perfect for maintaining the original slow-cooked flavor and texture.
Steaming Method: Place the meatballs in a steamer basket over simmering water. Cover and steam for about 10 minutes. This method keeps the meatballs moist and tender without adding extra fat or calories.
