Using a crockpot is a great way to keep the taco meat warm for a party. Twenty minutes before adding in the cooked taco meat turn the slow cooker on to warm up. This slow cooker tip keeps the meat at temperature. After cooking the taco meat on the stove, then place it into a slow cooker. u003cbr/u003eu003cbr/u003eI don’t recommend placing cold taco meat into the slow cooker to warm up. It will take too long to get to temperature, and this can lead to unsafe bacteria growth. Also, it might not get warm enough in time for the party. My advice is to warm it up before putting it in the slow cooker to stay warm.u003cbr/u003eu003cbr/u003eYou can also entirely make taco meat in the slow cooker and set it to warm after it’s done cooking.
