Beef Tallow Snacks Are a $1.1B Category — Built on a Fat McDonald's Dropped in 1990

Beef tallow has crossed from wellness subculture into mainstream snacks. Sales of foods containing beef tallow hit $1.1 billion for the 52 weeks ending March 2026, up 275% over three years, per Spins data cited by Food Dive, and major brands such as Utz and Conagra have launched tallow-cooked products [1]. Whole Foods named tallow its top 2026 trend [2].

Tallow is rendered beef fat, solid at room temperature, used for frying, pastry and soap for centuries. It was the original fast-food fryer oil — McDonald's cooked its fries in beef tallow until 1990, when it switched to vegetable oil, a switch still argued about because the tallow fries are remembered as the flavor benchmark [3]. The 2026 snack boom is that fat returning to the pantry and the chip aisle.

The food-history value is that a $1.1 billion 2026 category is a fat returning from a 35-year exile. The "new" snack fat is the fat McDonald's left behind. For the full history of beef tallow and the french-fries origin dispute, see the articles below.
