When it comes to sides that pair well with duck breasts, the options are practically endless.  Classic accompaniments for a roasted or pan-seared duck breast include creamy mashed potatoes, roasted sweet potatoes, steamed green beans, or other seasonal vegetables like Brussels sprouts or cauliflower.  For a more flavorful option, consider pairing your duck breast with a crunchy salad, such as a kale and roasted almond salad, or a fruity side dish like an apple chutney.  You can also serve it with classic starchy sides like couscous, quinoa, or rice.  Try glazing your duck breast in a sweet-and-savory sauce or basting it in a honey-mustard glaze to make the most of the flavor. The sauce's sweetness will pair perfectly with the saltiness of the duck and any sides you choose.
