Are Applebee's Sauteed Mushrooms & Onions High in Histamine?

Applebee's Sauteed Mushrooms & Onions

Moderate histamine

Sauteed mushrooms and onions land at a moderate histamine level, mostly from the mushrooms.

Most of this is cooked to order, which is the best case for histamine. Even so, a restaurant kitchen preps ahead and holds things warm through a service, so freshness varies more than it would at home. The rating above comes from the chain's published ingredients. If a dish is borderline for you, asking how it is prepared tells you more than the menu does.

Dairy

This side is simply onions and mushrooms cooked in a buttery soybean oil blend.

Mushrooms — they carry a moderate amount of histamine, which is the main thing setting this dish's level.
Liquid butter alternative soybean oil — the oil blend used to saute also sits at a moderate level, so it adds to the picture alongside the mushrooms.

If you want something gentler, plain sauteed onions on their own would sit lower.
