What oil does STK Steakhouse fry in?
STK Steakhouse most likely cooks with soybean and canola oil, but the chain has not confirmed it.
In detail: Deep-fries a handful of apps and sides (triple-cooked truffle fries, cheesy tater tots, crispy calamari, egg rolls) in a shared fryer - a Chicago location's allergen note confirms the egg rolls are fried in the same oil as the fish and chips; steaks and mains are seared/grilled, not fried. No official allergen PDF, nutrition page, or franchise disclosure document was found that names the actual fryer oil, so the soybean or canola blend typical of scratch-kitchen steakhouse chains is assumed, not confirmed.

Build my orderWhy the frying oil matters
Most fast-food chains fry in seed oils like soybean, canola, corn, or a blend of them, which are high in polyunsaturated fat (PUFA). A handful still use beef tallow or other stable fats, which are far lower in PUFA. The oil a kitchen fries in is the single biggest driver of how much seed oil ends up on your plate. See the full breakdown on the STK Steakhouse report card, or where it lands on the Seed Oil Index. See which chains fry in real fats on Tallow Watch.
