Louisiana Voodoo Fries Recipe
Introduction
Louisiana Voodoo Fries are a bold and creamy twist on classic fries, topped with a spicy, cheesy sauce infused with ranch seasoning and cayenne pepper. This dish is perfect for those who love a flavorful snack or side with a little kick.

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 until golden brown following package instructions.
- Step 3: In a saucepan over medium heat, melt the butter and whisk in the flour until combined. Cook for about 2 minutes to remove the raw flour taste.
- Step 4: Gradually add the milk while whisking continuously. Stir in salt, white pepper, ranch seasoning powder, and half of the cayenne powder.
- Step 5: Lower the heat to medium-low and cook the sauce, stirring occasionally, until it thickens, about 5 minutes. Then add the shredded cheddar cheese and stir until melted and smooth.
- Step 6: Pour the cheese sauce evenly over the cooked fries. Sprinkle the remaining cayenne powder on top if desired, and serve warm.
Tips & Variations
- For extra crispiness, double bake the fries by baking them once, letting them cool, then baking again before adding the sauce.
- Substitute white cheddar with sharp or smoked cheddar for a different flavor profile.
- To make it vegetarian-friendly, check that the ranch seasoning powder contains no animal products or use a homemade blend.
- Add cooked bacon bits or chopped green onions on top for added texture and flavor.
Storage
Store any leftover fries and cheese sauce separately in airtight containers in the refrigerator for up to 2 days. Reheat the fries in the oven or air fryer to restore crispiness, and warm the cheese sauce gently on the stove or in the microwave before serving.

Can I use homemade fries instead of frozen?
Yes, homemade fries work great. Just make sure they are cooked through and crispy before adding the cheese sauce.

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 and cook fries: Preheat your oven or air fryer to 400°F. 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 they are golden brown and crispy, ensuring they cook evenly.
- Make roux: While the fries are cooking, melt 2 tablespoons of butter in a saucepan over medium heat. Whisk in 2 tablespoons of all-purpose flour and cook this mixture for about 2 minutes to form a roux, which will help thicken the cheese sauce.
- Add milk and seasoning: Gradually pour in 2 cups of milk while whisking continuously to avoid lumps. Stir in 1/2 teaspoon salt, 1/4 teaspoon ground white pepper, 2 teaspoons ranch seasoning powder, and half of the cayenne powder (1/4 teaspoon) for heat. Reduce the heat to medium-low and cook the sauce for approximately 5 minutes until it thickens.
- Incorporate cheese: Once thickened, stir in 8 ounces of shredded white cheddar cheese until fully melted and the sauce becomes creamy and smooth. Taste and adjust seasoning if necessary, optionally adding the remaining cayenne pepper for extra spice.
- Assemble and serve: Pour the warm cheese sauce generously over the cooked fries. Serve immediately while hot and creamy for the best flavor and texture.
Notes
- You can choose either oven baking or air frying for cooking the fries based on your preference and available equipment.
- Adjust the amount of cayenne pepper to control the spice level according to your taste.
- Use whole milk for a creamier sauce; low-fat milk will make the sauce less rich.
- For a gluten-free version, use gluten-free flour instead of all-purpose flour.
- Leftover cheese sauce can be stored in the refrigerator for up to 2 days and gently reheated.
