Potato-Butternut Gratin With Poblano Béchamel
The mild sweetness of butternut squash pairs particularly well with Mexican flavors of poblano chile and cumin. Goat cheese brightens and enriches the flavor, and toasty almonds offer a welcome textural contrast. Try to get a squash with a long neck, as slices from that section are easiest to work with. It’s important to allow the gratin to rest for 20 minutes after baking so the juices that accumulate can thicken and absorb into the vegetables.
