Wash and scrub your potatoes, then pat dry with a paper towel. Peel the potatoes, then slice them into thick fries, about ¾ inch by 3 inches.
02 -
Bring 1 quart of water to a simmer with 3 tablespoons of salt. Using a basket or colander, place the potatoes over the boiling water, cover and steam them for about 10-12 minutes, or until a knife inserted comes out clean. Be careful not to cook potatoes all the way through - you don't want them mushy or falling apart.
03 -
Transfer the potatoes to a bowl and drizzle them with the olive oil. Toss them carefully so that the oil coats each fry evenly.
04 -
Using a slotted spoon, transfer the potatoes to a nonstick baking sheet and arrange them in a single, even layer. Bake in a 450°F oven for about 10 minutes, turn your pan around for even baking, then bake for an additional 5-10 minutes, watching carefully to prevent burning.

While your potatoes are baking, make your cheese sauce. In a medium sized sauce pan, melt the butter over medium heat. Slowly whisk in the flour and milk and stir until no lumps remain. Add the shredded cheese and stir until fully melted and the sauce is creamy.

Once your fries are ready, remove them from the oven, and sprinkle the cajun seasoning over them. Mix thoroughly. Top the fries with a drizzle of ranch dressing and about ¼ cup of the cheese sauce. Serve with the remaining cheese sauce on the side for dipping.
