Yes, meatball sauce can be cooked in a slow cooker! Simply add all of the ingredients to the pot and cook on low heat for about 4-6 hours. The ingredients will break down and release their natural flavours into the dish, creating a thick and delicious sauce that’s perfect for serving over pasta or polenta. If you want to speed up the process, you can pre-cook your meatballs before adding them to the slow cooker. This way, they’ll already be partially cooked when they go in so they won’t take as long to finish cooking in the sauce.
