This leeks recipe will have you rethinking your go-to vegetable side dishes. Shake that green-salad rut—or shelve the standard broccoli or green-bean side—in favor of our French-inflected Buttered Leeks and Radishes. The dish comes together in half an hour, and involves little more than chopping and sautéing. When shopping for leeks, look for firm, straight stalks with white bases that give way to dark green leaves. Store the onion-like vegetable unwashed in the refrigerator, and wash chopped leeks thoroughly in cold water before cooking them. This preparation, which gets a touch of decadence from butter and chicken broth, doesn’t disappoint.
