Jet's publishes a full component-level ingredient list and four of its five crusts name a seed oil outright - corn oil in Hand Tossed and Deep Dish, soybean in Thin, canola in Gluten-Free - so a standard Jet's pizza carries seed oil before any topping goes on it. The base of crust, pizza sauce and premium mozzarella is at least additive-free, which is where the rest of the menu falls down.
Rated from Jet's own component-level ingredient page (jetspizza.com/ingredients, 47 components read 2026-08-25). Seed oils: 4 of the 5 crusts name one. Hand Tossed and Deep Dish list CORN OIL, Thin lists SOYBEAN OIL, Gluten-Free lists CANOLA OIL; only the Seasoned Cauliflower Crust is free of it, so a standard pizza carries seed oil before a single topping. The Butter flavorized crust is SOYBEAN OIL + HYDROGENATED SOYBEAN OIL, the Butter Garlic dipping cup the same, Jet's Wings are BLANCHED IN VEGETABLE OIL, and 5 of 6 dressings list soybean or corn oil. 21 of 47 components in total. No swap offered. What is clean: Jet's Famous Pizza Sauce, all four cheeses and nearly every topping. Additives: 33 of 47 components carry at least one, but the base build is not one of them - Hand Tossed crust, the pizza sauce and Premium Mozzarella are all additive-free. Pepperoni carries BHA, BHT and sodium nitrite.
