Cream Sweet Potato Soufflé
1 1/2 pounds (3 medium) sweet potatoes or yams
5 eggs, separated
8 ounces cream cheese
1/2 teaspoon salt
1/2 teaspoon black pepper
2 tablespoons + 1/2 cup honey (optional)
1/2 cup freshly grated Parmigiano Reggiano cheese
2 tablespoons chopped fresh thyme
Preheat the oven to 325° F.
Bake the unpeeled sweet potatoes for 1-1 1/2 hours, until easily pierced with a knife. Let them cool completely, then peel and cut into large chunks. Set aside.
Cream the egg yolks and cream cheese in a food processor or with an electric mixer until creamy and pale yellow, about 3 minutes. Add the cooked sweet potatoes and process for 2-3 minutes, until smooth. Add the salt, pepper, 2 tablespoons of the honey, the cheese and thyme and process for 1 more minute, until well mixed. Pour into a large bowl (if you’ve been using a food processor) and set aside.
Beat the egg whites with an electric mixer until they form stiff peaks, about 3-4 minutes. Fold the egg whites into the sweet potato mixture 1/3 at a time, being careful not to overmix.
Pour into a lightly greased 9 x 13-inch baking dish. Bake for 30-40 minutes, until the top is lightly browned and beginning to crack.
Serve drizzled with the remaining 1/2 cup honey, if you wish a sweeter soufflé.
