First, spray the slow cooker with non-stick cooking spray.
Then, whisk cornstarch into the milk until it dissolves. Pour into the slow cooker and then add the rest of the ingredients.Â
Mix everything together and then cover the slow cooker.
Cook on low for 1.5 to 2 hours stirring every 15-30 minutes to be sure the edges don’t burn. We recommend NOT cooking this on high as it can easily burn.
When all the cheese is melted and smooth, stir and turn the slow cooker to warm.Â
Serve with tortilla chips, vegetables, or pretzels.
Notes
*American cheese will come in slices, and we just tore the slices into smaller pieces for this recipe.
