Ingredients
- 26 ounces frozen French fries
- 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
- Step 1: Preheat your oven or air fryer to 400°F.
- Step 2: Arrange frozen fries in a single layer on a baking sheet or air fryer basket. Bake according to package instructions until golden brown and crispy.
- Step 3: In a saucepan over medium heat, melt butter and whisk in flour until fully combined. Cook for about 2 minutes to form a roux.
- Step 4: Gradually add milk while whisking continuously to avoid lumps. Stir in salt, white pepper, ranch seasoning powder, and half of the cayenne powder.
- Step 5: Lower heat to medium-low and cook the sauce until it thickens, about 5 minutes. Then, stir in the shredded white cheddar cheese until melted and creamy.
- Step 6: Pour the cheese sauce evenly over the cooked fries. Sprinkle the remaining cayenne powder on top if you like extra heat. Serve warm and enjoy.
Tips & Variations
- For a smokier flavor, try adding a pinch of smoked paprika to the cheese sauce.
- Use sharp white cheddar for a stronger cheese taste or mix in Monterey Jack for extra creaminess.
- Swap frozen fries with fresh-cut potatoes for a homemade touch, just bake them longer until crispy.
- Adjust the cayenne powder to your preferred spice level or omit for a milder dish.
Storage
Store leftover fries and cheese sauce separately in airtight containers in the refrigerator for up to 3 days. Reheat fries in the oven or air fryer to regain crispiness, and warm the cheese sauce gently on the stovetop or microwave before combining.

FAQs
Can I make the cheese sauce ahead of time?
Yes, you can prepare the cheese sauce in advance and refrigerate it. Reheat gently before pouring over the fries to ensure it stays smooth and creamy.
What can I use instead of ranch seasoning powder?
If you don’t have ranch seasoning, you can substitute with a mix of garlic powder, onion powder, dried dill, and a pinch of salt to mimic the flavor.

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 oven or air fryer: Set your oven or air fryer to 400°F (204°C) to prepare for cooking the fries.
- Cook the fries: Arrange the frozen French fries in a single layer either on a baking sheet or in an air fryer basket. Bake or air fry until golden brown and crispy according to the package instructions, usually about 20-25 minutes for the oven, or 15-20 minutes in an air fryer, shaking halfway through.
- Make the roux: In a medium saucepan over medium heat, melt the butter. Whisk in the all-purpose flour and cook the mixture for about 2 minutes to remove the raw flour taste, stirring constantly.
- Add milk and seasonings: Gradually pour in the milk while whisking continuously to avoid lumps. Stir in salt, ground white pepper, ranch seasoning powder, and half of the cayenne powder (about 1/4 teaspoon) to infuse the sauce with flavor and some heat.
- Thicken the sauce: Lower the heat to medium-low and continue cooking the sauce, stirring frequently, until it thickens to a creamy consistency, approximately 5 minutes.
- Melt the cheese: Remove the saucepan from heat, then stir in the shredded white cheddar cheese until fully melted and smooth, creating a rich, creamy cheese sauce. Add the remaining cayenne powder if you desire extra spice.
- Combine and serve: Pour the warm cheese sauce generously over the hot, crispy fries and serve immediately for a decadent snack or appetizer.
Notes
- You can use either oven or air fryer for cooking the fries depending on your preference or equipment.
- Adjust the cayenne pepper to your preferred spice level; add more if you like it hotter.
- For extra crispiness, toss fries halfway through cooking in the oven or air fryer.
- Use freshly shredded cheese for better melting and creamier sauce.
- This recipe pairs well with a side of ranch dressing or hot sauce for dipping.
