In a large sauce pot, melt butter over medium heat. Add onions and saute until soft. Add garlic and saute for another minute.
Add chicken broth and cumin, then bring to a boil. Reduce heat and cover, simmering for about 5 minutes.
Stir in the chicken, half-and-half, cheese, corn, chiles, and tomatoes. Cook and stir over medium-low heat until cheese is melted.
Top with cilantro and tortilla chips. Serve warm.
Notes
Because this recipe is based mostly on the white cheddar, using a quality cheese will up your flavor and texture. You can substitute the white cheddar for another type of cheese, but for the best taste, we would recommend keeping the recipe as is.You can get sharp white cheddar from the deli section of pretty much any grocery store, but our favorite cheese off the shelves is Tillamook's Sharp White Cheddar (this isn't sponsored, it's just our favorite). It costs less than a lot of the cheeses behind the counter, but the quality and texture is top notch.Recipe slightly adapted from All Recipes.
