Louisiana Voodoo Fries Recipe
Introduction
Louisiana Voodoo Fries are a spicy, cheesy twist on classic French fries perfect for kicking up your snack game. Crispy fries topped with a creamy, seasoned white cheddar sauce make for an irresistible treat that’s easy to prepare at home.

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 (200°C).
- Step 2: Arrange the frozen French fries in a single layer on a baking sheet or in the air fryer basket. Bake or air fry according to package instructions until golden brown and crispy.
- Step 3: Meanwhile, in a saucepan over medium heat, melt the butter. Whisk in the flour until combined and cook for about 2 minutes to form a roux.
- Step 4: Gradually add the milk while whisking continuously to avoid lumps. Stir in salt, ground white pepper, ranch seasoning powder, and half of the cayenne powder.
- Step 5: Lower the heat to medium-low and cook the sauce, stirring often, until it thickens, about 5 minutes. Remove from heat and stir in the shredded white cheddar cheese until melted and creamy.
- Step 6: Drizzle the cheese sauce over the cooked fries, sprinkle with the remaining cayenne powder for extra heat, and serve warm.
Tips & Variations
- For a milder version, reduce or omit the cayenne powder. For extra smoky flavor, add a pinch of smoked paprika to the cheese sauce.
- Use sharp white cheddar for a more pronounced cheese taste.
- Try topping the fries with chopped green onions or cooked bacon bits for added texture.
Storage
Store any leftover fries and cheese sauce separately in airtight containers in the refrigerator for up to 2 days. Reheat the fries in an oven or air fryer to restore crispiness, and gently warm the cheese sauce on the stovetop or microwave before combining.

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. Preheat your oven or air fryer to 400°F to ensure the fries cook evenly and become crispy.
- Cook the fries. Arrange frozen fries in a single layer on a baking sheet or inside the air fryer basket. Bake or air fry according to package instructions, until fries are golden brown and crispy.
- Make a roux. In a medium saucepan over medium heat, melt the butter, then whisk in the all-purpose flour until fully combined. Cook this mixture for about 2 minutes to eliminate the raw flour taste.
- Prepare the cheese sauce. Gradually add the milk to the roux while whisking continuously to avoid lumps. Stir in salt, ground white pepper, ranch seasoning powder, and half of the cayenne powder.
- Thicken and add cheese. Lower the heat to medium-low and cook the mixture for about 5 minutes, stirring frequently, until the sauce thickens. Remove from heat and stir in the shredded white cheddar cheese until melted and creamy.
- Serve. Pour the rich cheese sauce evenly over the cooked fries, sprinkle the remaining cayenne powder on top if desired, and serve immediately while warm.
Notes
- For extra crispiness, pat fries dry before cooking or choose a higher temperature setting if using an air fryer.
- Adjust cayenne powder quantity to control the spice level according to your preference.
- Use freshly shredded cheese for better melting texture and flavor.
- If sauce becomes too thick, temper with a splash of milk to reach desired consistency.
- Serve with additional ranch dressing or hot sauce on the side for extra flavor options.
