Every Papa Murphy's crust, including the thin and stuffed versions, contains both a seed oil and an additive, though the take and bake model does mean the pizza is assembled fresh rather than held hot.
Papa Murphy's publishes ingredient statements through its own ingredient search. Of 108 food components, 48 contain a named seed oil and 56 contain an additive from our watchlist. Every crust they sell - Original Crust, Original Dough, Thin Crust and Stuffed Crust - contains both a seed oil and an additive, so there is no pizza on the menu that avoids either. The mozzarella reads clean. Their take and bake model means the pizza really is assembled fresh and never sits under a heat lamp, and that is a genuine point in their favor on processing, but it does not change what is in the dough you take home and bake.
