Try it soon - it is the best Queso!!
Queso ( I believe this may have come from Southern Living)
2 lbs. deli white American Cheese ( I like Boars Head)
1 small onion, diced
2 garlic cloves, minced
2 10 oz can Rotel Original
3/4 cup milk
1/2 - 1 tsp ground cumin ( I like it with 1 tsp)
1/2 tsp ground pepper
Place all 7 ingredients in a 6 quart slow cooker and cook on low for 3 hours, stirring every hour. (I did mine in the microwave)
If want to make ahead, place in container and freeze up to one month.
