Is Panera Bread Toasted Frontega Chicken® High in Histamine?

Panera Bread Toasted Frontega Chicken®

High histamine

This toasted sandwich is high, driven by the black pepper focaccia base.

Food here is usually assembled to order from components that were prepped earlier in the day, so it tends to be fresher than a drive-through and less fresh than cooking at home. Histamine builds up as protein foods sit, so how long the chicken or beef has been in the warmer matters as much as what is in the bowl. Treat the rating above as a starting point.

This is chicken with red onion and basil on a black pepper focaccia, and the bread is what drives it high.

The focaccia leads — the black pepper focaccia runs high, and it is the main reason the whole sandwich lands where it does.
The rest is milder — the red onion and basil sit on the lighter side, so they are not what pushes the rating up.

Moving to a fresh, non-focaccia roll is the single change that makes the biggest difference here.
