Cooking corned beef in a slow cooker can result in a tender, flavorful meal! You'll want to start with a brisket, usually with some seasoning packet included. Place it in the slow cooker with enough water or broth to cover it. Adding vegetables like carrots and potatoes in the last couple of hours can make it a complete meal. Cook on low for 8-10 hours until tender. Do you have any favorite ingredients you like to add to your corned beef? Or perhaps a recipe you're trying to recreate?
