Most conversations about "healthy restaurants" focus on calorie counts and macros. They miss the biggest variable: what oil the food is cooked in. A salad with soybean-oil dressing delivers far more omega-6 linoleic acid than a plate of grilled chicken cooked in butter. Here's how major chains and restaurant types rank by cooking fat.
Chain restaurants: ranked by oil quality
Based on published ingredient documentation from each chain's allergen pages.
Oil: Olive oil + avocado oil
One of the few major chains with NO seed oils. Publishes oil sourcing explicitly.
Oil: Olive oil (primary cooking fat)
Mediterranean-rooted menu, olive oil base. No seed oil fryers. Excellent for avoiding vegetable oils.
Oil: Rice bran oil + sunflower oil (rice only)
Uses rice bran oil for cooking — not a traditional seed oil, lower omega-6 than canola or soybean. Protein cooked on the grill. A reasonable option.
Oil: Peanut oil (frying)
~32% omega-6 linoleic acid — lower than soybean or sunflower, higher than tallow. Burger patty itself is clean.
Oil: Sunflower oil (~65% omega-6)
Uses sunflower oil for frying — highest omega-6 of any major chain. Despite its health-conscious reputation, one of the worst for seed oil.
Oil: Soybean oil (frying + all sauces)
Soybean oil in every single item. ~54% omega-6. No seed-oil-free option on the menu.
Restaurant types: what to expect
Before you pick a chain, the broader category of restaurant often predicts the oil quality.
How to order at any restaurant
Whether you're at a chain or an independent restaurant, these four rules reduce your seed oil intake without making you the person who interrogates the server on every visit:
Frequently asked questions
What are the healthiest places to eat out?
The healthiest chain restaurants are those that avoid seed oils in their cooking fats: Sweetgreen (olive and avocado oil), Cava (olive oil), Chipotle (rice bran oil — cleaner than soybean or canola), and True Food Kitchen. Independent farm-to-table restaurants and steakhouses that use butter or animal fats are generally better choices than fast food chains that deep-fry in vegetable oils.
Which fast food chains use the least seed oil?
Among major fast food chains: Sweetgreen and Cava actively use olive oil and avocado oil. Chipotle uses rice bran oil (better than canola or soybean oil). Five Guys uses peanut oil (lower omega-6 than soybean or sunflower oil). Chains to avoid if minimizing seed oil: Wingstop (soybean oil frying), In-N-Out (sunflower oil — highest omega-6 of any major chain), and Raising Cane's (canola oil).
How can you tell if a restaurant uses seed oils?
The fastest way is to check their published allergen or nutrition pages — most major chains publish this information. For independent restaurants, ask the server what oil is used for cooking and frying. Good signs: olive oil, butter, avocado oil, lard, or tallow listed as cooking fats. Red flags: 'vegetable oil,' soybean oil, canola oil, sunflower oil, or corn oil in ingredient lists.
Are steakhouses healthier than fast food?
Generally yes, from a seed oil standpoint. Most steakhouses cook proteins in butter or on high-heat grills that don't require added oil. The risk areas are sauces (which may contain soybean oil-based mayo or salad dressings) and any fried items. Ask for proteins cooked in butter rather than 'vegetable oil' and request dressings on the side so you can inspect the ingredient list.
What should you order at restaurants to avoid seed oils?
Order grilled or roasted proteins over fried ones. Choose olive oil or butter-dressed sides. Skip mayo-based sauces and dressings unless confirmed seed-oil-free. Ask for sauces on the side. At chain restaurants, focus on chains that publish their oil sourcing (Sweetgreen, Cava, Chipotle). At independent restaurants, ask directly and trust a good-faith answer from the kitchen.
