Prepare the Cajun spice mix. Whisk together the paprika, garlic powder, onion powder, salt, oregano, black pepper, and cayenne.
Cut the potatoes. Cut the potatoes into thin, even strips to make fries. Make sure they are of uniform thickness to ensure even cooking.
Prepare to fry. Add 3 inches of oil to a pot and heat it to 360°F (use a candy thermometer). While the oil is heating, set a wire rack over a baking sheet lined with aluminum foil.
Fry. Add a batch of potato strips to the hot oil (don’t overcrowd the pot) and fry for about 8 to 9 minutes or until golden brown and crisp, moving around occasionally with a spider skimmer. Remove the fries from the oil with the spider skimmer and allow them to drain on the wire rack. Bring the oil back to 360°F and repeat with the remaining fries.
Season. Once the oil has drained off of the fries, add them to a large bowl with the Cajun spice mix. Toss to coat the fries in the seasoning. Serve.
Notes
Uniform Fries: Aim for consistent thickness in your potato slices for even frying.
Right Temperature: Heat the oil to 360°F before frying. Use a candy thermometer for accuracy.
Fry in Batches: Avoid overloading the oil with too many potato strips at once to prevent temperature drop and soggy fries.
Stir for Even Cooking: Use a spider skimmer to gently stir the fries, ensuring they brown and crisp evenly on all sides.
To Taste: Customize the spice levels to your preference. Use less cayenne for milder fries or more smoked paprika for a smoky touch.
