Arby's crinkle vs curly fries.

Arby's is the only major chain in Frypedia with two meaningfully different fry recipes under one roof. The crinkle fries and curly fries look like variants of the same product, but they're not — the curly fries carry a wheat batter and roughly double the calories, almost triple the sodium, and come with a different allergen profile. For a reader deciding between the two, the differences are large enough to matter.

The gluten difference is the biggest one.

Arby's curly fries are coated in a seasoned batter that includes enriched wheat flour. The wheat is not a trace contaminant — it's a direct ingredient in the fry itself. For celiac disease, non-celiac gluten sensitivity, or wheat allergy, Arby's curly fries are a definitive no.

Arby's crinkle fries contain no wheat as an ingredient. The potato is coated only in oil and seasoning, no batter. On ingredient alone, the crinkle fry passes the gluten-free bar.

The hitch: Arby's fryer is shared between the two products. If curly fries have been in the oil — which they always have, because they're on the menu — the wheat batter sheds trace amounts of gluten into the shared oil. Crinkle fries cooked in that same oil pick up trace wheat gluten. For celiac disease, which can be triggered by amounts as small as 20 parts per million, this is enough to disqualify the crinkle fry too.

For non-celiac wheat sensitivity, the crinkle may be workable depending on individual threshold. For celiac disease, neither Arby's fry is a safe order.

The calorie and sodium gap is huge.

Both fries are small-portioned by chain standards, but the curly fries are substantially heavier on both dimensions. A small crinkle order delivers 240 calories and about 380 mg sodium. A small curly order delivers 410 calories and about 930 mg sodium — roughly 70% more calories and 2.5x more sodium.

The sodium gap is particularly stark. 930 mg from a small side order is 40% of the FDA's recommended daily limit. The seasoned batter is doing almost all of that work — the potato and oil contribute minimally, and the seasoning blend is what carries both the flavor identity and the sodium load.

If you order Arby's curly fries, order water with them.

The 2024 crinkle reformulation.

Arby's reintroduced crinkle fries in 2024 after a years-long absence (the curly fry had been Arby's only fry on most menus from 2008 to 2023). The crinkle launch was positioned as a return to tradition — the pre-2008 Arby's menu had carried both. The 2024 crinkle recipe is a plain crinkle fry: potato, oil, salt, nothing more.

The crinkle is a lower-calorie, lower-sodium option, and for many gluten-sensitive diners the ingredient-level change matters even if the shared-fryer concern persists. For diners who are gluten-free by preference rather than medical necessity, the crinkle is a workable choice.

Verdict.

If you have celiac disease: neither fry is safe. The curly is wheat-containing by ingredient; the crinkle is cross-contaminated in the shared fryer. For celiacs ordering at Arby's, skip the fries entirely and consider the Market Fresh salads instead.

If you're watching sodium or calories: the crinkle is dramatically better. 240 cal / 380 mg sodium versus 410 cal / 930 mg sodium is a meaningful gap.

If you're ordering for flavor: the curly is Arby's signature for a reason. The seasoning is distinctive, and the batter adds textural interest. The crinkle is a plainer, more traditional fast-food fry.

If you're alpha-gal syndrome, halal, or vegan: both fries pass the ingredient bar — vegetable oil, no beef derivatives, no mammalian fats. The seasoning blend on the curly is plant-derived.
