What oil does Morton's The Steakhouse fry in?
Morton's The Steakhouse most likely fries in soybean oil, but the chain has not confirmed it.
In detail: Steaks are grilled/broiled (finishing broiler up to 1000F) and butter-finished, so beef entrees are low-PUFA; Cajun Ribeye is marinated in a neutral oil before broiling. Morton's is a Landry's brand and does not publish nutrition/allergen or fryer-oil data, so fried sides (matchstick fries) are assumed cooked in soybean oil, higher-PUFA-wins per dataset convention (mashed.com steak-secrets writeup + mortons.com dinner menu, both accessed 07.11.26).

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 Morton's The Steakhouse report card, or where it lands on the Seed Oil Index. See which chains fry in real fats on Tallow Watch.
