  3. Sweet and Sour Sauce: For a blend of sweet and tangy flavors with an Asian twist, try using a sweet and sour sauce. This sauce usually combines ingredients like vinegar, sugar, soy sauce, and various seasonings. It complements the meatballs beautifully, creating a harmonious balance of flavors.
  4. Teriyaki Sauce: Teriyaki sauce adds a savory and slightly sweet taste to your meatballs. With its soy sauce base, it brings a delightful umami flavor to the dish.

The Basics of Crock Pot Cooking

Before we delve into the specifics of cooking frozen meatballs, let’s understand the basics of using a slow cooker (Otherwise known as a Crock Pot). This kitchen appliance is designed to cook food at a low temperature over an extended period, allowing flavors to meld and ingredients to become tender.

Slow cookers come in various sizes, so make sure to choose one that suits your needs. For this recipe, we use a 7-quart Crock Pot. If you are using something larger you will want to add more sauce to ensure it can cover the meatballs.

The versatility of a slow cooker makes it an ideal option for busy individuals who want to enjoy delicious, home-cooked meals without spending excessive time in the kitchen.

How to Store and Reheat


  1. Cool Down: Allow the cooked meatballs and sauce to cool down to room temperature before storing them. This helps prevent condensation and keeps the meatballs from becoming soggy.
  2. Refrigerator Storage: If you plan to consume the leftovers within a few days, transfer the meatballs and any remaining sauce to an airtight container or resealable plastic bag. Place them in the refrigerator, where they can be safely stored for up to 3-4 days.
  3. Freezer Storage: For longer-term storage, you can freeze the cooked meatballs. Place them and the sauce in a freezer-safe container or bag, making sure to remove as much air as possible. Label the container with the date and freeze for up to 3 months.

When you’re ready to enjoy your frozen meatballs again, follow these steps to reheat them:

  1. Stovetop Reheating: To reheat on the stovetop, place the thawed or refrigerated meatballs and sauce in a saucepan or skillet. Cook over medium-low heat, stirring occasionally, until heated through. This method helps the meatballs retain their moisture and flavors.
  2. Microwave Reheating: If you prefer a quicker reheating method, you can use the microwave. Place the meatballs and sauce in a microwave-safe dish and cover with a microwave-safe lid or microwave-safe plastic wrap. Heat in 30-second intervals, stirring in between, until the meatballs are heated to your desired temperature.

Tips for Reheating

  • To prevent drying out the meatballs, avoid overheating. Reheat just until the meatballs are heated through.
  • If the sauce has thickened or become too dry, you can add a small amount of water, broth, or additional sauce to the pan to maintain moisture and prevent sticking.
