Chicken Parmentier
Serves 6.
Note: The inspiration for the dish is hachis Parmentier, the French version of shepherd's pie and one of the tastiest ways to make a meal out of leftovers or inexpensive cuts of meat. This version depends less on leftovers and more on what's in the refrigerator. Use the vegetables called for here, or tinker with your own medley: Cubes of butternut squash and turnips are good options, as are leeks and jarred, drained chestnuts. Serve in a single dish or cook individual portions in deep gratin dishes. To make ahead: The chicken and mashed sweet potatoes can be cooked (separately), cooled and refrigerated a day in advance. The casserole(s) can be assembled, covered and refrigerated for up to 2 days. The baked casseroles can be reheated, covered, in a conventional or microwave oven. From Dorie Greenspan.
