  • 1 tablespoon unsalted butter
  • 1 tablespoon all-purpose flour
  • 1 cup whole milk
  • 12 ounces Chihuahua or Monterey jack cheese, coarsely grated
  • 1/4 cup grated Parmesan
  • 1 tablespoon canola oil
  • 1 1/2 pounds ground beef
  • 1 teaspoon chili powder
  • 1/2 teaspoon garlic powder
  • 1/4 cup cilantro
  • 4 hamburger buns, split and lightly toasted
  • 4 tomato slices
  • 4 onion slices
  • 12 blue or yellow corn tortilla chips, coarsely crushed
  • Kosher salt and freshly ground black pepper, to taste

 

For the queso sauce:
Melt the butter in a small saucepan over medium heat. Whisk in the flour and cook for 1 minute. Add the milk, increase the heat to high and cook, whisking constantly, until slightly thickened, about 5 minutes. Remove from the heat and whisk in the cheese until melted; add the Parmesan and season with salt and pepper, to taste. Keep warm.

Mix the beef with the chili powder, garlic powder and cilantro. Shape the ground beef into 4 round patties about 1 1/2 inches thick and season each burger on both sides with salt and pepper, to taste. Cook the burgers until golden brown on both sides and cooked to medium, about 8 minutes.

Put the burgers on the buns and top each with a few tablespoons of the queso sauce, tomatoes, onions and chips.
