Sweet Potato Casserole with Hazelnut Streusel

Created for the 3 1/10 qt. stoneware au gratin dish
Serves 12 – 14

Ingredients:

For the topping:

• 1 1/4 cups all-purpose flour
• 1/4 cup rolled oats
• 1/2 cup finely chopped hazelnuts
• 1/2 cup sugar
• 1/4 cup brown sugar
• 1 teaspoon ground cinnamon
• 1/4 teaspoon ground cloves
• 1/4 teaspoon salt
• 8 tablespoons (1 stick) unsalted butter

For the filling:

• 6 pounds sweet potatoes, roasted, peeled and pureed
• 3 large egg yolks
• 1 whole egg
• 1 1/2 cups half-and-half
• 1/3 cup maple syrup, plus more to taste
• 1 teaspoon salt
• 1/2 teaspoon ground nutmeg
• 1 1/2 teaspoons ground cinnamon
• 1 1/2 teaspoons vanilla extract
• 3 tablespoons orange juice
• 5 tablespoons unsalted butter, plus more for the baking dish
• 1/2 teaspoon fresh cracked pepper

Directions:

Preheat oven to 375 F. Butter the gratin dish.

Prepare the streusel: Melt the butter and let it cool slightly. In a medium bowl, mix together all the dry ingredients for the topping with a fork. While stirring, slowly drizzle in the butter until you have uneven lumps and crumbs. Refrigerate for 15 minutes while preparing the potatoes.

Place the pureed sweet potatoes in a large bowl. Set aside.

In a medium bowl, whisk together egg yolks, whole egg and half-and-half until well-blended. Whisk in 1/3 cup maple syrup, salt, nutmeg, cinnamon, vanilla and orange juice.
Gently whisk the egg mixture into the potatoes until well-blended. Add butter and stir until smooth.

Taste for seasoning and sweetness. Adjust with the addition of a few more tablespoons of maple syrup, or salt and pepper.

Transfer the potato mixture to the gratin dish and smooth with a spatula.

Remove topping from refrigerator and crumble it over the potatoes.

Bake 20 minutes. Rotate the dish and bake another 20 – 25 minutes, until the top is crisp and browned. Let cool 15 minutes before serving.
