Is Papa Murphy's Onion Mix High in Histamine?

Papa Murphy's Onion Mix

Low histamine

This onion mix is low in histamine, just yellow onion, red onion, and scallions.

This is sold raw and you bake it at home, which is the freshest case on this whole list. Nothing sits in a warmer, and you control how long it waits between the shop and the oven. Refrigerate it as soon as you get home and bake it the same day, because histamine builds up as protein foods sit whether that happens in a kitchen or in your fridge.

This topping is a simple blend of fresh yellow onion, red onion, and scallions.

Fresh onions and scallions — none of these are aged, cured, or fermented, so there is nothing here building histamine, which is why the mix stays low.
A friendly base topping — because it is just fresh alliums, this is an easy add that keeps a pizza on the milder side.

This is one of the more comfortable toppings to build around.
