In the Southwest, October is potimarron season. You find them at every market, bright orange and shaped like a fat onion, and they are one of the easiest squashes to cook: the skin softens completely as it simmers, so there is nothing to peel. The flesh has a gentle, nutty sweetness, which is where the French name comes from, half potiron (pumpkin) and half marron (chestnut).
A pinch of Espelette pepper from the Basque Country gives this soup a soft warmth without real heat, and toasted hazelnuts on top bring crunch and healthy fats. Make a big pot on Sunday and you have lunches ready for half the week. On days when you need something more filling, my Warming Lentil, Squash and Ginger Soup adds plant protein to the bowl.
