Frequently asked

Does O'Neill's UK use seed oils?

Based on our menu research, O'Neill's UK cooks with: rapeseed oil and vegetable oil blend. Across the 105 menu items we analyzed, it averages 7.7g estimated PUFA per item, earning a seed-oil grade of C (High Risk).

What oil does O'Neill's UK cook with?

Our research indicates: rapeseed (vegetable) oil in the fryers, the Mitchells & Butlers estate standard shared with All Bar One, Harvester and Toby Carvery; the seasoned chunky chips, waffle fries, Magners-battered fish, wholetail scampi, southern-fried chicken fillets, chicken tenders, halloumi fries, panko calamari, beer-battered mushrooms, spring rolls and battered onion rings all come out of the same rapeseed fryers, and the burger sauce, buttermilk ranch, tartare, Sriracha mayo, coleslaw and houmous are rapeseed-oil emulsions, so the burgers (all served WITH chunky chips) and the loaded waffle fries carry by far the most PUFA; chargrilled grills, gammon, sausage & mash and the sticky puddings are butter/beef-led and score much lower. Preparation can vary by location, so treat PUFA numbers as estimates.

What are seed oils?

Seed oils — canola, soybean, sunflower, corn, and similar vegetable oils — are extracted from seeds using high heat and chemical solvents. They are very high in polyunsaturated fats (PUFAs), which are unstable at cooking temperatures and can oxidize easily. Many health-conscious eaters choose to minimize seed oils and prefer foods cooked in beef tallow, butter, coconut oil, or olive oil instead. This page shows estimated PUFA grams per menu item to help you make more informed choices. These are estimates — actual values vary by preparation and location. New to the topic?
