KFC's Secret Recipe Fries replaced the much-loved Potato Wedges in 2020, and the new product doubles down on processing. The fries contain two separate wheat ingredients — bleached wheat flour AND durum wheat semolina — plus MSG, hydrolyzed soy protein, and a dedicated seasoning pack. They're vegan by ingredients, but firmly off-limits for anyone avoiding gluten.

R.I.P. Potato Wedges
In spring/summer 2020 KFC replaced its long-running Potato Wedges with the new Secret Recipe Fries. The Wedges had a simpler ingredient profile — potatoes, oil, seasoned coating. The Secret Recipe Fries are more heavily engineered: two types of wheat flour, MSG, hydrolyzed soy protein. The company has since occasionally brought the Wedges back as limited-time offers.

Oil & fryer setup
Primary oil
Canola/soybean blend
Vegetable oil blend used across the menu. Refined soybean oil is FDA-exempt from major allergen labeling.
Fryer setup
Shared with chicken
KFC fries and chicken share the same fryer at most locations. Original Recipe, Chicken Tenders, and Nuggets all contain milk.
Cross-contamination
High
Shared oil with milk-containing chicken means fries are not safe for severe dairy allergies regardless of ingredient list.
International variants
UK/Australia differ
KFC UK and KFC Australia use different recipes and in some cases offer vegan burger patties. Coverage on this page is the U.S. menu.

Important — read before you eat
Ingredient formulations change, sometimes with no public announcement. Allergen risk at any fast-food restaurant depends on the specific location, the time of day, and the staff on shift. For severe allergies, confirm ingredients with the restaurant at the point of ordering, and when in doubt, ask about fryer and equipment cross-contact.
