The Knoxville American burger tradition: hand-pattied beef from Mitchell Family Farms or East Tennessee farms, on a Flour Head Bakery bun with Sweetwater.
Litton's in Fountain City has run the Knoxville canonical burger since 1946. Stock and Barrel formalized the East Tennessee farm-sourcing approach in 2013 with Mitchell Family Farms beef, Flour Head Bakery buns and Sweetwater Valley cheddar. The Stack burger style runs across multiple Knoxville rooms now.
