Which fast food fries are vegan?

"Vegan by ingredient" and "actually vegan" are different standards. Only eight major chains cook their fries in a dedicated fryer — meaning no cross-contact with chicken, fish, or dairy-containing fried items — and use no animal-derived cooking oils or flavorings: Five Guys, Chick-fil-A, In-N-Out, Mission BBQ, Hopdoddy, P. Terry's, Dick's Drive-In, and Elevation Burger. These are the eight chains where vegans can eat fries without cross-contact concerns.

# Chain Calories Serving size
01 Dick's Drive-In 300 Regular Fries (99g)

How this ranking works Values shown are per-serving as published by each chain's official nutrition disclosure. Serving sizes vary — a Five Guys "Little" is roughly twice the weight of a McDonald's "Medium." The comparison is most meaningful chain-to-chain at equivalent order size.

Which fast food fries are vegan? The short answer.

Eight fast-food chains in the United States serve fries that are genuinely vegan — meaning plant-based ingredients, plant-based cooking oil, and a dedicated fryer with no animal-protein cross-contact. Those eight chains are Five Guys, Chick-fil-A, In-N-Out, Mission BBQ, Hopdoddy, P. Terry's, Dick's Drive-In, and Elevation Burger. We call these the Cold Eight.

Most other fast-food chains' fries are vegan by ingredient (plant-based potatoes and oil) but cooked in fryers shared with chicken, fish, or wheat-breaded items. For strict vegans, that shared-oil cross-contact disqualifies the fry — animal proteins contaminate the cooking medium even if they don't appear in the fry's ingredient list. A handful of chains go further and put animal ingredients directly in their fry preparation: McDonald's (natural beef flavor), Steak 'n Shake (beef tallow), Bojangles (beef fat blend), Portillo's (beef tallow blend), and Smashburger (beef tallow + canola).

FAQ

Are McDonald's fries vegan?
No. McDonald's U.S. fries contain "natural beef flavor" derived from milk and hydrolyzed wheat, and they're fried in shared oil. McDonald's fries have not been vegan in the U.S. since 1990. (UK and European locations use different preparation and are typically marked as vegan by the chain there.)
Are Burger King fries vegan?
By ingredient, Burger King's fries are vegan — the chain's coating is rice-flour-based, not wheat, and the oil is vegetable oil. But they share the fryer with chicken and breaded items, so strict vegans should treat them as ingredient-clean but cross-contact-compromised.
Are Taco Bell's Nacho Fries vegan?
The Nacho Fries themselves are vegan by ingredient, but the standard order comes with Nacho Cheese Sauce (dairy). Order the fries without the sauce or with a vegan sauce substitute (Taco Bell's red or green salsa) to keep the order fully plant-based. Shared fryer caveat still applies.
Are Wendy's fries vegan?
Ingredient-wise, yes — Wendy's Natural-Cut Sea Salt fries are vegan. But they share fryer oil with wheat-breaded chicken. For ingredient-level vegan diners, they're fine; for strict vegans who care about shared cooking surfaces, they're a caution.
Are KFC fries vegan?
Ingredient-wise KFC's Secret Recipe Fries are vegan. But they're cooked in the same fryer as the wheat-breaded fried chicken that defines the chain. Strict vegans should treat this as cross-contact-compromised.
Are Five Guys fries vegan?
Yes — Five Guys is one of the Cold Eight. The chain runs a dedicated fry fryer with 100% peanut oil, hand-cut potatoes, and no breaded items anywhere on the menu. Vegan-safe with confidence.
Are In-N-Out fries vegan?
Yes. In-N-Out hand-cuts Kennebec potatoes in-store and fries them in 100% sunflower oil in a dedicated fryer. No beef tallow (despite persistent social-media rumors). No shared fryer. Strict vegan-safe.
Are Chick-fil-A's Waffle Fries vegan?
Yes — at the U.S. chain level. Waffle Fries are cooked in canola oil in a fryer dedicated to potato products (the peanut oil used for the chicken is a separate fryer). No animal ingredients in the fry itself. The fry is strict-vegan-safe; just be aware the chain's broader menu is chicken-centric.
Are Arby's curly fries vegan?
Ingredient-wise, yes — Arby's curly fries have no animal-derived ingredients. But they share the fryer with wheat-breaded and animal-protein items, which matters for strict-vegan cross-contact. See the Arby's chain page for full detail.
Which fast food fries are cooked in beef tallow?
Five chains on Frypedia use beef in their fry preparation: McDonald's (natural beef flavor since the 1990 switch), Steak 'n Shake (100% beef tallow since January 2025), Bojangles (canola + beef fat blend), Portillo's (vegetable oil + beef tallow blend), and Smashburger (beef tallow + canola blend). These five are all disqualified for vegan diets. See The tallow reversion for the cultural shift behind these choices.
Are fast food fries always vegetarian?
No — five chains (listed above) use beef-derived ingredients in their fry preparation, which rules out strict vegetarianism as well as veganism. The remaining 49 chains on Frypedia serve fries that are plant-based at the ingredient level (though shared-fryer cross-contact is the norm for most of them).
