Follow these simple steps to create your delightful Slow Cooker Turkey Meatballs:

1. Prepare Ingredients: In a large mixing bowl, combine ground turkey, breadcrumbs, grated Parmesan cheese, egg, minced garlic, parsley, oregano, basil, salt, and pepper.
2. Mix Gently: Use your hands or a large spoon to gently mix all ingredients together until well combined but do not overmix, as this can make the meatballs tough.
3. Shape Meatballs: Scoop out portions of the mixture and roll them into 1.5-inch meatballs, placing them aside on a baking sheet or plate.
4. Arrange in Slow Cooker: Spray the slow cooker with cooking spray or use a liner. Place the meatballs in the slow cooker, ensuring they are in a single layer.
5. Add Sauce: Pour marinara sauce over the meatballs until they are fully covered.
6. Cook: Cover the slow cooker and set it to cook on low for 4-6 hours or on high for 2-3 hours. Meatballs are ready when they reach an internal temperature of 165°F.
7. Serve: Carefully remove the meatballs from the slow cooker and serve them with extra marinara sauce over pasta, in a sub, or as is!

Following these steps will lead to a wonderful batch of Slow Cooker Turkey Meatballs that you’ll be proud to serve!
