Instructions

Cook the Fries:

  • Prepare the frozen French fries according to the package instructions — bake, air fry, or deep fry until crispy.
  • Sprinkle the hot fries with Cajun seasoning, starting with less and adding more to taste, then toss to coat evenly.

Make the Cheese Sauce:

  • Make the sauce while the fries are cooking. In a medium saucepan, melt the butter over a medium heat.
  • Whisk in the flour and cook for 1 to 2 minutes until the flour mixture (roux) turns golden and bubbly.
  • Slowly whisk in the milk, stirring constantly to avoid lumps.
  • Cook until the mixture thickens, 3 to 5 minutes.
  • Remove the saucepan from the heat. Add the shredded cheddar and pepper jack a handful at a time, stirring until melted and smooth.
  • Adding the cheese off the heat helps it melt smoothly without becoming oily or grainy.
  • For extra heat, sprinkle in a bit of chili powder, if liked.

Assemble the Dish:

  • Transfer the seasoned fries onto a warmed serving platter.
  • Drizzle the warm cheese sauce generously over them.
  • Drizzle the ranch over the cheese sauce or serve on the side for dipping.
  • Serve immediately with your preferred toppings.

Notes

Get the fries really crisp: They're about to be covered in cheese sauce and ranch, so I cook them a little on the crisp side. That gives them a much better chance of holding up under all those toppings.
Season while they're hot: Toss the Cajun seasoning with the fries as soon as they come out of the oven, fryer or air fryer so it sticks well.
Shred your own cheese: Freshly shredded cheese melts more smoothly into the sauce. Pre-shredded cheese can sometimes give you a grainier result.
Take the sauce off the heat: Once the milk mixture has thickened, remove the pan from the heat before stirring in the cheese. This helps keep the cheese sauce smooth rather than oily or grainy.
Don't assemble them early: Have everything ready and add the cheese sauce and ranch just before serving. Once the sauces go on, the fries will start losing their crispness.
