While this recipe was designed with a one-pot, quick-cooking Instant Pot method in mind, you can certainly make this recipe with a conventional slow cooker. Prepare the ground meat in your favorite large sauté pan, following the directions as indicated. Once browned, turn off the heat and stir in only the tomato paste and crushed tomatoes (if your sauté pan cannot hold all of the crushed tomatoes, only add half). Scrape the bottom of the pan to remove any caramelized bits. Then, transfer the cooked meat and all tomatoes to your slow cooker. Stir in the rest of the ingredients, except for the broth. A slow cooker will not require as much liquid as a pressure cooker does. Cook for 4 hours on high or 8 hours on low. Enjoy!
