Fast food chains have spent the past decade revising ingredient lists as shoppers pay closer attention to additives and labels. In the burger category, several national brands now say their burgers are made without artificial preservatives in key menu items. Here are five chains that have publicly stated that standard in the U.S.
Shake Shack
Shake Shack said on its U.S. nutrition and ingredients information that its 100% Angus beef contains no hormones or antibiotics and that its burgers are made without artificial ingredients or preservatives in the beef. The New York-based chain, founded in 2004, has grown to hundreds of locations across the U.S. and abroad.
That does not mean every item on the menu is preservative-free. Shake Shack’s posted ingredient details show that toppings, sauces, buns, and sides can vary by item and supplier. For customers, the key confirmed fact is that the burger beef itself is the part the company identifies as free of artificial preservatives.
In-N-Out Burger
In-N-Out Burger has long kept a short menu, and the California chain says its hamburger patties are made from 100% USDA ground chuck with no additives, fillers, or preservatives. The company, founded in Baldwin Park in 1948, still prepares burgers in a tighter geographic footprint than most national chains.
Its public product statements are specific to the beef patties and core burger build. In-N-Out also says its buns are baked without preservatives, according to company materials, though the full ingredient list still depends on each component. The chain has not positioned that standard as an industrywide pledge beyond its own menu.
Wendy’s
Wendy’s said in prior company ingredient updates that its hamburger patties are fresh, never frozen in many markets, and made with beef that does not include fillers, additives, or preservatives. The Dublin, Ohio-based chain operates thousands of restaurants, giving the policy broad reach across the U.S.
The company has also used clean-label language in broader menu updates, including changes announced in the mid-2010s. Still, Wendy’s posted nutrition information makes clear that a full sandwich includes several parts beyond the patty. The confirmed preservative-free claim applies to the beef used in its hamburger patties.
BurgerFi
BurgerFi has marketed its burgers around Angus beef standards for years, saying its beef is raised without antibiotics, steroids, chemicals, or additives. The Florida-based chain, founded in 2011, has repeatedly described its burger program as built around cleaner ingredients than traditional fast-food competitors.
According to BurgerFi’s public menu descriptions, the chain’s beef is positioned as free of artificial preservatives in the burger itself. As with other chains, that statement does not automatically cover every bun, sauce, or cheese option. The company’s ingredient claims are centered on the burger beef that forms the base of its sandwiches.
Elevation Burger
Elevation Burger said its burgers are made with 100% organic, grass-fed, free-range beef, and the chain has promoted a simple ingredient approach since its 2005 launch in Virginia. Its brand standards have emphasized fewer additives and a more limited ingredient list than many legacy burger chains.
The chain’s public-facing product language points to burgers without artificial preservatives in the beef. Because Elevation Burger has a smaller footprint than giants like Wendy’s, availability varies by market and not every consumer will have a nearby location. Even so, its ingredient standards remain part of the company’s core national branding.
