Yield 8 servings

Number Of Ingredients 7

3 lbs. sweet potatoes, peeled and sliced 1/2 inch thick
3 Tbls. unsalted butter, melted
3/4 tsp. coarse sea salt
6 medium poblano chiles
3 small onions, sliced crosswise 1/4 inch thick, separated into rings
1 cup(loosely packed) cilantro leaves
1/3 cup creme fraiche or sour cream

Steps:

1.Preheat the oven to 375'. Generously butter a 3-quart gratin dish, and set aside. Grease a cookie sheet and arrange the sweet potatoes on the sheet. Brush the potatoes with 1 1/2 Tbls. of the melted butter and spinkle with the salt. 2.Roast the poblanos directly over a gas flame or under the broiler,turning, until charred all over. Transfer the poblanos to a bowl, cover with plastic and let them steam for 15 minutes. Peel, core and seed the chiles, then cut them into 1/4 inch strips. 3.Transfer the poblanos to a bowl, add the onion rings and toss with the remaining 1 1/2 Tbls. of butter. In the gratin dish arrange the sweet potatoes in an overlapping layer. Scatter part of the chile/onion mixture over the sweet potatoes, continue with this process,finishing with a layer of sweet potatoes covered with the reserved poblano strips. 4.Reduce the oven temperature to 350' and roast the sweet potatoes for about 35 minutes, or until the poblanos and onions are tender and are just beginning to brown. Scatter the cilantro leaves on top, drizzle with creme fraiche and serve.
