Preheat oven to 450 degrees F. Line a large baking sheet (or two smaller sheets) with parchment paper; set aside.

Fill a large pot with water and bring to a boil. Cut washed potatoes into 1⁄4-inch strips and place in boiling water for 3 minutes. Immediately pour potatoes into a colander to drain and rinse in cold water.

Add paprika, salt, garlic powder, onion powder, cayenne pepper and flour to a gallon-sized resealable bag. Seal and shake to combine.

Add potatoes to the bag, seal and shake until fries are evenly coated in seasoning. Spread in an even layer on a prepared pan then spray generously with cooking spray. Bake for 20-25 minutes, turning halfway through.
