What Oil Does Wendy's Use to Fry Their Fries? The Exact Blend

Wendy's Natural-Cut French Fries are fried in a specific vegetable oil blend. According to Wendy's official ingredients, the oil contains: soybean oil, canola oil, cottonseed oil, and hydrogenated soybean oil. This blend is used for all fried items in the restaurant.

Oil ComponentRoleNotes
Soybean oilPrimary oilHigh in polyunsaturated fats
Canola oilSecondary oilLower in saturated fat
Cottonseed oilFlavor and stabilityCommon in restaurant frying
Hydrogenated soybean oilTexture and shelf lifeFully hydrogenated, not partially (so trans fat per serving is 0 g)

Wendy's confirms they use a non-hydrogenated oil blend for frying, meaning the hydrogenated soybean oil is fully hydrogenated, which does not create trans fats. The fries are cooked in 100% vegetable oil — no animal fats.

How to Make Wendy's-Style Fries at Home: Oil Choices and Steps

To replicate Wendy's fries at home, use a similar oil blend. Here's how:

  1. Choose your oil: Use a blend of soybean oil and canola oil (or a high-smoke-point vegetable oil like canola or sunflower).
  2. Cut the potatoes: Cut russet potatoes into thin strips (about 1/4 inch). Soak in cold water for 30 minutes to remove starch.
  3. Blanch first: Fry at 325°F for 3-4 minutes until tender but not brown. Drain and cool.
  4. Final fry: Increase oil to 375°F and fry again for 2-3 minutes until golden and crispy.
  5. Season: Immediately toss with salt while hot. Serve fresh.

For the closest match, use a soybean oil blend. Avoid olive oil or butter for deep frying.
