Sweet potatoes are boiled until fork tender and then blended with spices, butter, brown sugar, vanilla and eggs then poured into a 2 quart pan and baked. The texture of this Sweet Potato Souffle is soft and fluffy, yet substantial.
Preheat the oven to 350°F and grease a 2 quart baking dish ( a souffle dish or baking dish) with nonstick cooking spray.
Peel and cut the sweet potatoes into ½ inch pieces.
3 pounds sweet potatoes
Bring a large pot of generously salted water to a boil. Boil the sweet potatoes until tender (15-20 minutes). Drain the potatoes and transfer while still hot to a food processor.
Add the butter and milk, puree until the potatoes are smooth and the butter is melted.
¼ cup whole milk, ½ cup salted butter
Add the remining ingredients to the potato mixture and puree for a couple minutes until completely smooth. Scrape the sides of the bowl as necessary. The mixture should have the consistency of a very think milkshake and be completely smooth.
½ cup packed brown sugar, ⅓ cup plain panko bread crumbs, 1 ¼ teaspoon kosher salt, 1 ¼ teaspoon fresh ginger, 1 tsp. baking powder, ½ teaspoon ground cinnamon, ½ teaspoon vanilla, ⅛ teaspoon cayenne pepper, 5 large eggs
Pour the mixture into the prepared baking dish and smooth the top.
Bake for 55-60 minutes. It will rise and puff up a couple of inches past the top of the dish and will still jiggle slightly when it's done.
Remove from the oven (it will deflate so that it is even or slightly below the top of the dish- this is normal).
