DEPENDS

Arby’s roast beef is gluten-free by ingredient — but it’s on a wheat bun in a wheat-heavy kitchen.

Depends — and leans cautious. Arby’s Classic Roast Beef is gluten-free by ingredient (beef, water, salt, sodium phosphates) with no wheat breading. But it’s normally on a wheat bun, Arby’s has no gluten-free menu, and the kitchen is wheat-heavy (buns, breaded chicken, Curly Fries which contain wheat flour and share fryers). Order roast beef “no bun,” but there’s no GF guarantee and real cross-contact risk. Severely sensitive celiacs should be cautious or avoid.

Arby’s roast beef is the classic “gluten-free recipe, not-gluten-free environment” fast-food case. The sliced roast beef itself has no wheat — but it’s normally served on a wheat bun, Arby’s has no gluten-free menu, and the kitchen is saturated with wheat (buns, breaded chicken, Curly Fries). The recipe and the kitchen give different answers.

What Arby’s Says

Per Arby’s allergen information: Classic Roast Beef is beef, water, salt, and sodium phosphates — gluten-free by ingredient, with no wheat-flour breading or marinade. However, Arby’s does NOT have a gluten-free menu, does not certify any item gluten-free, normally serves roast beef on a wheat bun, and cannot ensure any item is free from cross-contact. Per FDA labeling rules, the roast beef recipe contains no gluten-containing grains — but the kitchen does.

Important Note: Arby’s Curly Fries are NOT gluten-free — they contain wheat flour AND are cooked in shared fryers with breaded items. The roast beef bun is wheat. To get roast beef as gluten-free-by-ingredient, order it “no bun” (meat-only or in a salad/bowl format if available). Even then, the meat is sliced and handled in a shared, wheat-heavy kitchen — there is no gluten-free guarantee.

Frequently Asked Questions

Is Arby’s roast beef gluten-free?

By ingredient, yes — Arby’s Classic Roast Beef is beef, water, salt, and sodium phosphates, with no wheat-flour breading. But it’s normally served on a wheat bun, Arby’s has no gluten-free menu, and the kitchen is wheat-heavy. Order roast beef “no bun,” but there’s no GF guarantee and real cross-contact risk.

Are Arby’s Curly Fries gluten-free?

No. Arby’s Curly Fries contain wheat flour in the seasoned coating AND are cooked in shared fryers with breaded items. They are NOT gluten-free — a common Arby’s celiac mistake. Crinkle fries should also be verified due to shared-fryer risk.

How do I order Arby’s roast beef gluten-free?

Order the roast beef “no bun” — as a meat-only portion or in a salad/bowl format if the location offers one. This removes the obvious wheat source (the bun). Tell the staff it’s a celiac need and request clean handling. Be aware the meat is still sliced and prepared in a shared, wheat-heavy kitchen.

Can severely sensitive celiacs eat Arby’s roast beef?

They should be cautious or avoid it. The roast beef is gluten-free by ingredient, but Arby’s has no gluten-free menu, no dedicated prep, shared slicers, and a wheat-heavy kitchen (buns, breaded chicken, Curly Fries). A gluten-free recipe doesn’t guarantee a safe meal in that environment.

Does Arby’s have a gluten-free menu?

No. Arby’s does not have a gluten-free menu and does not certify any item gluten-free. It publishes an allergen guide that identifies wheat-containing items, but it cannot ensure any item is free from cross-contact. Use the allergen guide and order with caution.

Is the roast beef itself breaded or marinated?

No. Arby’s roast beef is sliced seasoned beef — beef, water, salt, and sodium phosphates — with no wheat-flour breading or wheat-based marinade. The meat recipe is gluten-free; the bun and the shared kitchen are where the gluten risk lies.
