Keep taco meat warm in a slow cooker for a party using this easy recipe. Cook the taco meat 3 hours prior to the party, and then turn the crock pot on low to keep the meat warm for up to 2 hours. Monitor the level of liquid in the meat to make sure it doesn't dry out. You can also keep it warm by browning it on the stove in a skillet over medium heat until cooked. Then, transfer it to a crockpot and keep it on warm for up to 2 hours. Monitor the moisture level of the meat, and add additional sauce as needed.
