Make a smooth, velvety nacho cheese sauce from scratch in under 15 minutes. This recipe delivers rich, restaurant-style flavor perfect for dipping chips or topping nachos and fries.

Ingredients

Scale
  • 2 tablespoons unsalted butter
  • 2 tablespoons all-purpose flour
  • 1 1/2 cups whole milk
  • 8 ounces sharp cheddar cheese, freshly shredded
  • 4 ounces Monterey Jack cheese, freshly shredded
  • 1/2 teaspoon salt
  • 1/4 teaspoon garlic powder
  • Pinch of cayenne pepper (optional)

Instructions

  1. In a medium saucepan over medium heat, melt the butter.
  2. Whisk in the flour to create a smooth paste (a roux). Cook for one minute, stirring constantly.
  3. Gradually whisk in the whole milk until the mixture is smooth and begins to thicken slightly. Continue cooking until the sauce coats the back of a spoon, about 3 to 5 minutes. Do not let it boil rapidly.
  4. Reduce the heat to low. Add the shredded cheddar cheese and Monterey Jack cheese, a handful at a time, stirring constantly until each addition is fully melted and smooth before adding more. This step is key to avoiding graininess.
  5. Once all the cheese is incorporated and the sauce is velvety, stir in the salt, garlic powder, and cayenne pepper, if using.
  6. Remove from heat immediately. Serve warm over tortilla chips, fries, or tacos.

Notes

  • Always shred your cheese fresh from a block; pre-shredded cheese contains anti-caking agents that prevent smooth melting.
  • If the sauce thickens too much while sitting, whisk in a splash of warm milk to restore the desired consistency.
  • For a spicier kick, add a dash of hot sauce along with the seasonings.
