Ingredients

Frozen French fries (26 ounces): Use pre-cut frozen fries for convenience and crispy texture after baking.
Butter (2 tablespoons): Adds richness and helps create a smooth roux to thicken the cheese sauce.
All-purpose flour (2 tablespoons): Used to thicken the sauce, ensuring a creamy, velvety consistency.
Milk (2 cups): Provides the base liquid for the cheese sauce, making it rich and smooth.
Salt (1/2 teaspoon): Enhances all the flavors and balances the taste.
Ground white pepper (1/4 teaspoon): Adds a subtle heat and depth without overwhelming the cheese sauce.
Ranch seasoning powder (2 teaspoons): Infuses the sauce with that signature tangy, herbed ranch flavor.
Cayenne powder (1/2 teaspoon, divided): Offers a gentle, spicy kick that enlivens the dish and leaves a warm finish.
White cheddar cheese, shredded (8 ounces): Melts into the sauce to create a luscious, gooey topping with sharp flavor.

Instructions

Preheat and prepare fries: Start by preheating your oven or air fryer to 400°F. Arrange frozen French fries in a single layer on a baking sheet or in your air fryer basket. Baking or air frying fries this way ensures they become nice and crispy without sogginess, forming a solid base for the cheese sauce.
Make the roux: In a medium saucepan over medium heat, melt the butter. Whisk in the flour until a smooth paste forms and cook for about 2 minutes. This roux is essential for thickening the cheese sauce and preventing it from separating.
Prepare the cheese sauce: Slowly pour in the milk while continuously whisking to ensure a smooth mixture with no lumps. Add salt, ground white pepper, ranch seasoning powder, and half the cayenne powder. Stir gently and allow the sauce to simmer on medium-low heat until it thickens, about 5 minutes. This slow cooking develops the flavors and perfect thickness.
Add cheese and finish sauce: Remove the saucepan from the heat and stir in the shredded white cheddar cheese until fully melted and the sauce is creamy. Add the remaining cayenne powder to adjust the spice level to your taste. The result is a rich, cheesy sauce with a perfect balance of tang and heat.
Assemble and serve: Pour the warm Cajun ranch cheese sauce generously over the baked fries while still hot. Serve immediately for the best flavor and texture. These fries are irresistible when enjoyed fresh and gooey.

You Must Know

For the crispiest fries, avoid overcrowding the baking sheet or air fryer basket.
Adjust cayenne powder amount based on your preferred spice tolerance to customize the kick.
Use freshly shredded cheese instead of pre-shredded for a smoother melt and creamier sauce.

Storage Tips

Store any leftover fries and cheese sauce separately in airtight containers in the refrigerator for up to 2 days. Reheat fries in an air fryer or oven to regain crispness and warm cheese sauce gently on the stove, stirring to restore creaminess.

Serving Suggestions

Serve Louisiana Voodoo Fries as a hearty appetizer or alongside grilled chicken or burgers for a complete meal. They also pair wonderfully with cold beverages, making them ideal for game day or casual entertaining.

Professional Tips

Use full-fat milk for a richer cheese sauce; whole milk or 2% works best.
Experiment with adding chopped green onions or crispy bacon bits as toppings for extra texture and flavor.
Keep the sauce warm over low heat before serving to maintain the perfect pourable consistency.

FAQs

Can I use fresh potatoes instead of frozen fries?: Yes, but you’ll need to slice, soak, dry, and bake them to a crispy finish before adding the cheese sauce for best results.
Is ranch seasoning powder necessary?: It’s key for the signature ranch flavor, but you can substitute with garlic powder, onion powder, dill, and parsley to mimic a homemade ranch seasoning blend.
How spicy are these fries?: The cayenne provides a mild to medium heat. You can reduce or increase the amount according to your spice preference.
Can I prepare the cheese sauce in advance?: Yes, make the sauce ahead and gently reheat while stirring before pouring over freshly baked fries.
What cheese variations work well?: White cheddar is preferred for sharp flavor, but Monterey Jack or pepper jack add great creaminess and a hint of spice.
Can I make this recipe vegan or dairy-free?: You can substitute butter, milk, and cheese with vegan alternatives, but texture and flavor will be slightly different.
What sides complement Louisiana Voodoo Fries?: They pair excellently with smoked meats, grilled vegetables, or fresh garden salads to balance richness.
