Papa Murphy's Croutons
These croutons are moderate, since they are baked from wheat and barley flour with yeast.
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.
Papa Murphy's croutons land in the moderate band, not the high one. They are toasted bread cubes, and wheat flour, baker's yeast, and malted barley flour each rate moderate, which is what keeps them out of the low column.
Why papa murphy's croutons are rated moderate
There is nothing cured, aged, or fermented in these croutons, which is why they do not sit at the top. What is there is a yeast-leavened wheat bread with malted barley flour, and each of those three lands at moderate on this index, so together they hold the croutons in the middle. It helps to know that bread is low in protein, and histamine needs protein to form, so croutons are not a food that quietly builds histamine while it sits in a box. The moderate rating comes from what they are made of, not from how they are stored. That is also why some people with milder sensitivity handle a scattering of yeasted bread without much trouble while others find yeast is one of their reliable triggers.
What changes your risk
- Wheat flour and malted barley flour — both rate moderate, and they are the base of the whole crouton, so they set the floor for this item.
- Baker's yeast — leavening yeast rates moderate too and adds to the flours rather than balancing them.
- Sitting time is not the driver — croutons are dry and low in protein, so time in the box is a staleness question rather than a histamine one.
- Dehydrated garlic is not a liberator — garlic does not release histamine. Some people simply do not tolerate it, and that is individual rather than a histamine mechanism.
- The citric acid is not a red flag — a tangy note is not a sign of histamine, and acidity does not build it. It is there for the product, not against you.
Lower-histamine alternatives
At Papa Murphy's the items that sit lower on this index are Chicken, Onion Mix, and Zesty Herb Blend. There is no lower crouton or bread component on the menu here, so if yeasted wheat is one of your reliable triggers, the move is to build the rest of the order around those three rather than to look for a swap.
How to lower the risk
Papa Murphy's does not publish anything you can leave out of the croutons, so they are what they are: a toasted wheat and barley bread cube with oils, garlic, salt, and yeast. If croutons are a maybe for you rather than a no, what surrounds them usually matters more than they do, so keeping the rest of the order in the lower column with Chicken, Onion Mix, and Zesty Herb Blend is the practical lever. They also carry gluten, which is worth knowing if that is on your list separately.
Common questions
Are croutons high in histamine?
These are moderate, not high. Wheat flour, baker's yeast, and malted barley flour each rate moderate, and there is nothing cured, aged, or fermented in them.
Is it the yeast that causes reactions to croutons?
Baker's yeast rates moderate and is one of the three drivers here, along with wheat flour and malted barley flour. Some people find yeasted bread is a consistent trigger for them while others do not.
Does the garlic in these croutons release histamine?
No. Garlic is not a histamine liberator, and the dehydrated garlic here is not part of why the croutons rate moderate. Some people do not tolerate garlic for their own reasons, which is a separate issue.
Does toasting bread into croutons make it worse?
No. Drying and toasting do not build histamine. The rating comes from the flours and the yeast in the bread itself, not from the toasting step.
