Cooking Guide

Step 1
1

In a large heavy-bottomed pot, melt the butter over medium-high heat. Add the onions and sauté, stirring every few minutes, until deeply caramelized but not burnt, about 30 minutes.

The Why

Slow caramelization turns the onions' sharp sugars sweet and jammy, and that browned depth is the whole backbone of the soup's flavor.
