Step 1: Start with a Simple, No Fuss Base - Add the frozen meatballs directly into your slow cooker. There is no need to thaw them, which makes this step wonderfully simple and perfect for busy days.
Step 2: Build That Creamy Tuscan Sauce - In a medium bowl, combine the chicken broth, chopped sun dried tomatoes, heavy cream, Italian seasoning, and red pepper flakes. Stir everything together until it is smooth and well blended.
Step 3: Bring It All Together in the Slow Cooker - Pour the sauce over the meatballs in the slow cooker. Give everything a gentle stir so each meatball gets coated in that rich, flavorful sauce.
Step 4: Let Time Do the Heavy Lifting - Cover and cook on low for 4 hours. Make it a habit to give the meatballs a stir every hour. This helps them soak up all that flavor and keeps the sauce from settling or sticking.
Step 5: Add a Fresh Pop of Color and Flavor - About 15 minutes before the cooking time is up, add in the spinach. Stir it gently into the sauce and let it wilt down just until tender and vibrant.
Step 6: Serve It Up Cozy and Comforting - Serve the meatballs over mashed potatoes, pasta, or rice. Finish with a sprinkle of shredded Parmesan and bring it straight to the table while it is warm and inviting.
