Smashburger belongs in the beef tallow club, alongside McDonald's, Steak 'n Shake, Bojangles, and Portillo's. Per the chain's own official FAQ: "We currently use butter on the grill, beef tallow/canola oil in our fryers, and a blended oil on our Smash Fries." Both varieties of Smashburger fries contain animal fat. A significant disqualifier for vegetarians and vegans — and a common misconception, because the fries themselves contain no visible meat and Smashburger markets itself as a modern better-burger chain. It's not.

VERBATIM FROM SMASHBURGER'S OFFICIAL FAQ ⓘ
"We currently use butter on the grill, beef tallow/canola oil in our fryers, and a blended oil on our Smash Fries. Please be aware that all Smashburger menu items are prepared using shared equipment, including our fried items." — smashburger.com/faq
The "better-burger with beef tallow" pattern Smashburger joins a specific and noteworthy group: chains that position themselves as premium or modern better-burger concepts while still frying in beef tallow. McDonald's famously switched away from tallow in 1990 under pressure over saturated fat; Smashburger (founded 2007) went the other direction from day one. Whether you see this as a flaw or a feature depends on nutritional philosophy — some consumers specifically prefer tallow for flavor, saturated-fat stability, and seed-oil avoidance. Our position: that's fine, but the chain should be transparent about it. Smashburger is.
The Smash Fries vs Classic Fries distinction The Smash Fries — Smashburger's signature rosemary-olive-oil-garlic-seasoned fries — are cooked in the same beef-tallow fryer as the Classic Fries, then tossed in the olive oil and seasoning blend after frying. The olive-oil seasoning does not make the Smash Fries vegan. Both products are animal-fat-fried.
The gluten-free fryer question Smashburger's corporate position is that fries "are gluten free" while acknowledging shared equipment. Celiac patron reports are highly variable by location: some locations explicitly maintain dedicated fry fryers, others share with breaded items, and some report that even the "dedicated" fryer cooks breaded items when a main fryer goes down. Additionally, the Smash Fries seasoning coating introduces a separate GF variable. For celiac disease, call your specific Smashburger location before ordering.

Oil & fryer setup

Primary oil
Beef tallow + canola blend
Smashburger's official FAQ confirms the fryers use beef tallow blended with canola oil. Smash Fries additionally carry an olive-oil-rosemary-garlic coating after frying.
Fryer setup
Shared (varies by location)
Some locations maintain dedicated fry fryers; many don't. Cross-contact with wheat-breaded items (tots, chicken tenders, onion rings) is common.
Cross-contamination
Elevated
Beef tallow means fries are not plant-based to begin with. Adding shared-fryer cross-contact compounds the issue for celiac diners.
Format
Classic + Smash Fries
Two varieties: plain Classic Fries and signature Smash Fries (olive-oil-rosemary-garlic coated). Both beef-tallow-fried.
