Caramelize Onions: In the same skillet, add sliced onions and cook until golden brown and caramelized, about 10-15 minutes. Add to the slow cooker on top of the meatballs. Make Gravy: Mix beef broth, and Worcestershire sauce. Pour over meatballs and onions in the slow cooker. Cook: Set the slow cooker on low for 6-8 hours or high for 3-4 hours. Adjust seasoning with salt and pepper as needed. Garnish and Serve: Before serving, garnish with fresh thyme. Enjoy hot!
