Step 1: Add the Meatballs - Place the frozen Italian meatballs into an 8 quart slow cooker. Spread them out evenly to ensure they cook uniformly and soak up all the delicious flavors.
Step 2: Prepare the Creamy Tuscan Sauce - In a medium sized bowl, combine the chicken broth, chopped sun dried tomatoes, heavy cream, Italian seasoning, and red pepper flakes. Stir until everything is well blended and smooth.
Step 3: Pour and Coat - Pour the sauce evenly over the meatballs. Gently stir to ensure each meatball is coated in the creamy mixture. This step helps infuse every bite with rich Tuscan flavor.
Step 4: Slow Cook to Perfection - Cover the slow cooker and cook on low for 4 hours. Stir the meatballs once every hour to prevent sticking and to allow the flavors to develop evenly.
Step 5: Add the Spinach - About 15 minutes before the cooking time is complete, add the fresh spinach. Stir gently until the leaves wilt into the creamy sauce, adding both color and freshness.
Step 6: Serve and Finish - Spoon the meatballs and sauce over mashed potatoes, pasta, or rice. Sprinkle with shredded Parmesan cheese and serve warm. Gather your family around the table and enjoy every comforting bite.
