Before you start

Before beginning, ensure you have a clean workspace and your slow cooker is positioned on a flat, heat-resistant surface. Take the frozen turkey meatballs directly from the freezer to the slow cooker insert; there is no need to thaw them beforehand.

Gather your ketchup, brown sugar, and mustard. Have a whisk and a measuring cup ready to mix the sauce components thoroughly. Clear away any unnecessary items from the counter to make the assembly process quick and efficient.

Ingredients at a glance (4)
  • 24 frozen precooked turkey meatballs
  • 1 1/2 cups ketchup
  • 1/4 cup brown sugar
  • 1 tbsp yellow mustard

Instructions

Meatball placement

  1. Combine meatballs
    Place the frozen precooked turkey meatballs into the insert of the slow cooker, arranging them in an even layer to ensure they heat through consistently during the cooking process.
    Look for The meatballs should be distributed evenly across the bottom of the slow cooker insert.
    Tip Ensure the slow cooker insert is clean and dry before adding the frozen meatballs.

The meatballs should be arranged in a single, even layer at the bottom of the slow cooker.

This ensures that every piece has equal contact with the sauce and heat source, preventing some from staying cold while others become overcooked. Verify that the slow cooker is plugged in and ready to go.

Sauce infusion

  1. Prepare sauce
    In a separate measuring cup, whisk together the ketchup, brown sugar, and yellow mustard until the mixture is smooth and well combined. Pour the sauce evenly over the arranged meatballs.
    Look for The sauce should be uniform in color and consistency before being poured over the turkey.
    Tip Whisking the sauce ingredients before pouring helps prevent clumps of brown sugar.

The sauce should be poured evenly, ensuring every meatball is coated. After pouring, the mixture should look uniform. If you notice any dry spots on the meatballs, use a spoon to gently redistribute the sauce. The slow cooker lid should be placed firmly to trap the heat and moisture.

Final simmering

  1. Slow cook and serve
    Cover the slow cooker and cook on low for 4 hours. Once the time is up, ensure the internal temperature of the meatballs has reached 160°F (71°C). Stir gently with a large spoon to coat the meatballs thoroughly in the thickened sauce before serving.
    Look for The sauce will thicken and become glossy, and the meatballs will be heated through entirely.
    Safe temperature 160°F (71°C) internal temperature (ground meat)
    Tip Use a digital thermometer to check the center of the largest meatball for accuracy.

At the end of the cooking time, the sauce will have thickened significantly and smell tangy and sweet. The meatballs should be tender and hot throughout. Give the mixture a final, gentle stir to incorporate any sauce that has settled at the bottom before serving.

Common mistakes

A common mistake is adding too much liquid or failing to mix the sauce ingredients properly before pouring. Ensure the brown sugar is fully dissolved into the ketchup and mustard so you do not end up with pockets of sweetness or undissolved granules.

Another error is overcooking; while slow cookers are forgiving, leaving the meatballs on high for too long can cause the sauce to become overly reduced or even start to stick to the sides of the insert.

How to tell it’s done

The meatballs are ready when they are heated through completely. Use a food thermometer inserted into the center of a meatball to verify that it has reached an internal temperature of at least 160°F (71°C).

The sauce should appear glossy and thick, clinging to the surface of each meatball. If the sauce looks too thin, you can remove the lid for the final thirty minutes of cooking to allow some of the moisture to evaporate.
