The Best Seed Oil Free Restaurants in London (2026)
London is one of the most food-diverse cities in the world — and increasingly, it's also one of the best cities in Europe for eating without seed oils. From Hawksmoor's legendary beef-dripping chips to the lard-fried fish at The Fryer's Delight, London has a surprising number of kitchens that have never abandoned traditional cooking fats.
This guide covers every Unnasty-verified seed oil-free restaurant in London, with notes on what makes each one worth visiting.
Why Seed Oils Are a Problem in London Restaurants
Most London restaurants — like most restaurants worldwide — default to vegetable oil, sunflower oil, or rapeseed oil (the UK name for canola oil) for frying and cooking. These industrial seed oils are cheap, have a long shelf life, and are deeply embedded in commercial kitchen supply chains.
The problem is that these oils are extremely high in omega-6 linoleic acid, which oxidises rapidly at cooking temperatures and has been linked in multiple studies to systemic inflammation, metabolic dysfunction, and cardiovascular disease. The UK's reliance on rapeseed oil — marketed as 'heart healthy' — makes it particularly difficult to avoid in London's restaurant scene.

The Standout Picks
Hawksmoor
Hawksmoor is the gold standard for seed oil-free dining in London. The group — with locations in Covent Garden, Knightsbridge, Wood Wharf, and Borough Market — uses beef dripping for their famous chips and cooks their steaks in butter. It's one of the few restaurant groups in the UK that has publicly committed to traditional cooking fats. The Sunday roast at Hawksmoor is arguably the best in London.
The Fryer's Delight
The Fryer's Delight in Holborn is a London institution. Open since 1962, it's one of the last traditional chippies in central London that still fries in lard. The fish is fresh, the chips are crisp, and there's not a drop of sunflower oil in sight. It's cash only and closes early — plan accordingly.
Duck Frites
Duck Frites in Soho does exactly what the name suggests: duck fat fries. The burgers are cooked in beef tallow and the whole menu is built around the philosophy that animal fats make food taste better. They're right.
Flat Iron
Flat Iron is the best value seed oil-free steak in London. The single-cut flat iron steak is cooked in tallow, the chips are fried in tallow, and the whole operation is built for efficiency and quality. Multiple locations across the city.
Grain Mediterranean
Grain Mediterranean in Fitzrovia is the best option for plant-forward eating without seed oils. Everything is cooked in extra virgin olive oil, the menu rotates seasonally, and the grain bowls are genuinely excellent.
Tips for Eating Seed Oil Free in London
- Steakhouses are your safest bet — Hawksmoor, Flat Iron, and Sear all use beef dripping or tallow as a matter of tradition and flavour.
- Traditional chippies over modern fish & chip shops — old-school chippies like The Fryer's Delight and Superfish still use beef dripping or lard.
- Mediterranean and Lebanese restaurants often use olive oil — Terra Rossa and Grain Mediterranean are good examples.
- Avoid pub food — most London pubs use vegetable oil for everything. Gastropubs that source locally are the exception.
