- Step 3: In a saucepan over medium heat, melt the butter. Whisk in the flour until fully combined and cook for about 2 minutes to form a roux.

Ingredients
Fries
- 26 ounces frozen French fries
Cheese Sauce
- 2 tablespoons butter
- 2 tablespoons all-purpose flour
- 2 cups milk
- 1/2 teaspoon salt
- 1/4 teaspoon ground white pepper
- 2 teaspoons ranch seasoning powder
- 1/2 teaspoon cayenne powder (divided)
- 8 ounces white cheddar cheese, shredded
Instructions
- Preheat the cooking appliance: Preheat your oven or air fryer to 400°F to ensure a hot environment for cooking the fries evenly and achieving a crispy texture.
- Cook the fries: Arrange the frozen French fries in a single layer on a baking sheet or inside an air fryer basket. Bake or air fry according to the package instructions until they are golden brown and crispy.
- Prepare the roux: In a medium saucepan set over medium heat, melt the butter. Whisk in the all-purpose flour until the mixture is smooth and combined. Cook this roux for about 2 minutes to eliminate the raw flour taste and allow it to slightly brown.
- Add the milk and seasonings: Gradually pour in the milk while whisking continuously to prevent lumps. Stir in the salt, ground white pepper, ranch seasoning powder, and half of the cayenne powder. These seasonings infuse the sauce with creamy, spicy, and tangy flavors.
- Thicken the sauce and add cheese: Reduce the heat to medium-low and cook the sauce, stirring frequently, until it thickens and coats the back of a spoon, about 5 minutes. Remove from heat, then stir in the shredded white cheddar cheese until it melts completely, creating a rich and creamy cheese sauce.
- Assemble and serve: Pour the hot cheese sauce generously over the cooked fries. Serve immediately while warm for the best flavor and texture experience.
Notes
- For extra crispiness, toss fries with a little bit of oil before baking or air frying.
- If you prefer a milder sauce, reduce the cayenne pepper or omit it entirely.
- The sauce can be kept warm on low heat or reheated gently if needed; stir frequently to prevent it from separating.
- You can customize the sauce by adding cooked bacon bits or chopped green onions for added flavor and texture.
- This dish is best enjoyed fresh as fries may become soggy if left too long with the sauce.
