Rinse the potatoes well and dry them with a napkin. Peel off the skin and chop into chunky sticks about ¾ inch wide and 3 inches long.

Add 3 tablespoons of salt into one quart of simmering water. Set the potatoes in a steamer basket or colander above the water and cover them. Let them gently steam for 10-12 minutes—you're looking for a knife to slide in without resistance, but don't overcook or they'll break apart.

Place the steamed potatoes in a big bowl. Pour the olive oil over them and toss carefully. Make sure they're oiled evenly.

Grab a nonstick baking sheet and lay the fries on it in a single layer. Bake at 450°F for 10 minutes, then turn the tray so the fries cook evenly. Continue baking another 5-10 minutes, keeping an eye on them so they don't over-brown.

While those fries bake, whip up the cheese sauce. Warm butter over medium heat in a pot, then thoroughly mix in the flour and milk until smooth. Toss in the shredded cheddar and stir until melted and creamy.

Grab the fries from the oven and sprinkle Cajun seasoning on top. Toss to coat. Drizzle ranch dressing and pour over ¼ cup cheese sauce. Serve hot with extra cheese sauce on the side for dipping!
