Before you start

Before starting, ensure your slow cooker insert is clean and dry. Gather all your ingredients near the cooking station to streamline the assembly process. If your slow cooker has a specific setting for temperature, prepare to use the low setting for the best results.

Check that you have an accurate digital meat thermometer on hand to verify the internal temperature of the meatballs before adding the final layer of cheese, ensuring the meal is cooked through safely.

Ingredients at a glance (4)
  • 20 count raw chicken meatballs
  • 2 cups marinara sauce
  • 1 tsp Italian seasoning
  • 1 cup shredded mozzarella cheese

Instructions

Assembly phase

  1. Arrange the meatballs
    Place the raw chicken meatballs in a single layer at the bottom of the slow cooker insert. Ensure they are arranged snugly to cook evenly.
    Look for Meatballs should be settled in the base of the slow cooker.
    Tip Do not stack the meatballs too high so they simmer evenly in the sauce.

At this point, the meatballs are arranged in a neat, single layer. The slow cooker is loaded and ready for the sauce and seasonings. Everything should look orderly and prepared for the long, slow heat that will tenderize the meat and infuse it with the rich flavors of the marinara and Italian herbs.

Simmering phase

  1. Add sauce and seasonings
    Pour the marinara sauce over the chicken meatballs. Sprinkle the Italian seasoning evenly across the top of the sauce to ensure the flavors distribute while heating.
    Look for The sauce should completely cover the meatballs.
    Tip Use a gentle hand when pouring to avoid splashing the sides of the cooker.

During this phase, the aroma of simmering tomatoes and herbs will fill the kitchen. The sauce begins to bubble, and the meatballs slowly poach in the liquid. Check to ensure the lid is properly seated and that the slow cooker is set to the correct low temperature for consistent, gentle heat.

Final finish

  1. Cook and melt cheese
    Cover and cook on low for 3 hours. Once the meatballs reach an internal temperature of 165°F (74°C), sprinkle the mozzarella cheese over the top. Cover for an additional 5 minutes or until the cheese is fully melted and bubbly.
    Look for Cheese will be melted and sauce will be simmering.
    Safe temperature 165°F (74°C) internal temperature (poultry)
    Tip Keep the lid on to trap the heat and melt the cheese quickly.

The final stage involves the addition of the mozzarella cheese. Once the cheese is added, the lid goes back on for just a few minutes.

You are looking for the cheese to be completely melted and slightly bubbly. The meatballs are now ready to serve, coated in the rich, cheesy, and savory marinara sauce.

Common mistakes

A common mistake is overcrowding the slow cooker with too many layers of meatballs, which can prevent even cooking. Stick to a single layer for the best results. Another error is checking the internal temperature too early; give the meatballs the full time to ensure they are safe to eat.

Finally, avoid lifting the lid frequently during the cooking process, as this releases heat and moisture, which can significantly lengthen the required cooking time for the dish.

How to tell it’s done

The meatballs are considered done when they reach an internal temperature of 165°F (74°C) when measured with a food thermometer. At this stage, the meatballs should feel firm to the touch and be heated through to the center.

The marinara sauce should be bubbling gently around the edges of the cooker, and the meatballs should be visibly plump and coated in the thickened, savory tomato sauce.

  • Poultry: 165°F (74°C) in the thickest part
  • Ground meat: 160°F (71°C) in the thickest part
