Instructions
Preparation Steps
Cube the white American cheese into small, even pieces to help it melt evenly.
In a medium saucepan over medium-low heat, melt the butter. Stir in the cornstarch slurry (cornstarch whisked with 1 tablespoon cold half-and-half) and cook for 30 seconds to activate.
Slowly add the remaining half-and-half to the pan, whisking constantly until smooth and warm but not boiling.
Gradually add the cubed cheese to the warm milk mixture, stirring continuously until the cheese is fully melted and the mixture is silky.
Stir in the diced green chiles, chopped jalapeño, garlic powder, ground cumin, lime juice, and salt. Taste and adjust seasoning or consistency (add a splash more half-and-half if too thick).
Keep the queso warm over very low heat, stirring occasionally. Garnish with chopped cilantro and serve immediately with tortilla chips or use as desired.
Notes
For extra smooth queso, melt cheese slowly and avoid high heat. Leftovers can be reheated gently with a splash of milk.
