Bake at a high heat or use an air fryer until edges are deeply golden. If using frozen fries just toss with extra Cajun seasoning after cooking to layer in flavor.
- Make the Cheese Sauce:
- Start your roux by melting butter in a saucepan over medium heat then whisk in flour. Let it cook for a minute or two until the mixture smells nutty being careful it does not brown too much. Gradually add milk whisking steadily to prevent clumping and cook until it thickens to coat the back of a spoon.

Cheddar is my favorite ingredient in this dish—I love how it melts into the sauce and brings richness to every bite. Some of my most fun evenings with my family have started around a platter of these fries with everyone picking their favorite toppings and diving in together.
Storage Tips
While these fries are best served hot and fresh you can keep extras in the fridge for up to two days. Store the fries cheese sauce and voodoo sauce separately to prevent sogginess. Reheat fries in an air fryer or hot oven until crisp then warm sauces gently before assembling.
Ingredient Substitutions
Use sweet potato fries for an earthier spin or try waffle fries for extra crunch. Swap dairy cheese and milk with vegan alternatives for a fully plant-based version. Feel free to mix in other seasoning blends such as Creole spice for a different Louisiana vibe.
