Ingredients
For the Nacho Cheese Sauce
-
4 tablespoons butter
-
4 tablespoons all-purpose flour
-
1½ cups milk
-
2 cups Mexican-blend cheese or a mix of Monterey Jack, mozzarella, and cheddar
-
1 teaspoon nacho, taco, or fajita seasoning
For the Nachos
-
1 (16-ounce) bag tortilla chips
-
1 can black beans, rinsed and drained
-
1 bell pepper, diced
-
1 cup frozen corn, thawed
-
1 tomato, seeded and diced
-
½ cup sour cream
-
1 cup guacamole or 1 ripe avocado, cut into chunks
-
1 lime, cut into wedges
-
Pickled onions, to taste
Instructions
-
Make the cheese sauce. Melt the butter in a medium saucepan over low to medium heat.
-
Prepare the roux. Sprinkle in the flour and whisk continuously for 1–2 minutes, until the mixture thickens and forms a smooth paste.
-
Add the milk. Gradually whisk in about ½ cup of milk until incorporated. Slowly add the remaining milk, stirring continuously to prevent lumps. Cook until the sauce is hot and small bubbles begin to appear.
-
Add cheese and seasoning. Stir in the Mexican-blend cheese and nacho seasoning until the cheese melts and the sauce is smooth. Reduce the heat as needed to prevent scorching.
-
Arrange the chips. Spread the tortilla chips across a large sheet pan in an even layer.
-
Add the toppings. Pour the warm cheese sauce over the chips. Scatter the black beans, bell pepper, corn, and diced tomato across the top.
-
Finish and serve. Add the guacamole or avocado, sour cream, pickled onions, and any optional toppings. Serve immediately with lime wedges.
Notes
-
Whisk continuously: Adding the milk gradually helps create a smooth cheese sauce without lumps.
-
Use freshly grated cheese: It often melts more smoothly than pre-shredded cheese, which may contain anti-caking agents.
-
Keep the chips crunchy: Add the cheese sauce and toppings just before serving, since moisture softens tortilla chips over time.
-
Layer strategically: Distribute beans and vegetables evenly so every portion gets a variety of toppings.
-
Serve immediately: Nachos are at their best while the chips are crisp and the cheese sauce is warm.
