Make this creamy, smooth nacho cheese sauce in under 10 minutes using only five simple ingredients. It is perfect for dipping chips, topping fries, or serving as a game day appetizer.

Ingredients

Scale
  • 1 cup whole milk
  • 4 tablespoons unsalted butter
  • 4 tablespoons all-purpose flour
  • 8 ounces sharp cheddar cheese, shredded
  • 1/4 teaspoon salt (or to taste)

Instructions

  1. Combine the milk and butter in a small saucepan over medium heat. Heat until the butter melts and the mixture is warm, but do not boil.
  2. In a separate small bowl, whisk together the flour and salt.
  3. Gradually whisk the flour mixture into the warm milk and butter mixture. Continue whisking constantly until the mixture thickens into a smooth roux, about 2 to 3 minutes.
  4. Remove the saucepan from the heat. Add the shredded cheddar cheese one handful at a time, stirring continuously until each addition is fully melted and smooth before adding the next.
  5. Return the pan to very low heat if needed to keep the sauce melted, stirring constantly. Do not allow the sauce to boil once the cheese is added, as this can cause it to separate.
  6. Taste and adjust salt if necessary. Serve immediately over your favorite snacks.

Notes

  • For a Taco Bell copycat flavor, add 1/4 teaspoon of onion powder and a small pinch of cayenne pepper with the flour mixture.
  • Shred your own cheese from a block for the smoothest results; pre-shredded cheese often contains anti-caking agents that can make the sauce grainy.
  • If the sauce becomes too thick upon standing, whisk in a tablespoon of milk until you reach your desired consistency.
