A Chipotle copycat, this Slow Cooker Beef Barbacoa is cooked slowly in a Crock Pot to a tender state creating the perfect shredded beef for your tacos or burrito bowls.
Place onions in the bottom of the slow cooker bowl. Combine spices to make a rub. Rub mixture over the meat and place on top of onions. Pour in lime juice and apple cider vinegar.
