Are Applebee's Grilled Onions High in Histamine?

Applebee's Grilled Onions

Moderate histamine

These grilled onions are moderate, driven by the soybean oil they are cooked in.

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.

Sliced onions cooked down with soybean oil, salt, garlic, and spices.

Liquid and hydrogenated soybean oil — this is the moderate driver here, the cooking fat the onions are prepared in.
The onions themselves — onion is naturally on the gentler side, so the level really comes from the oil rather than the vegetable.

Onions sauteed in plain fresh butter or a little oil would sit lower than this prepared version.
