Pumpkin and Potato Gratin with Bacon & Gruyere Cheese

Serves 8 to 10

6 cups peeled fresh pumpkin, cut into 1-inch cubes (about 1½ pounds)
3 large russet potatoes, peeled and cut into 1-inch cubes
salt, to taste
1/2 stick unsalted butter (4 tablespoons), room temperature, divided
½ teaspoon freshly grated nutmeg
2 teaspoons finely chopped fresh sage
freshly ground black pepper, to taste
3 large eggs
2 cups shredded Gruyère cheese (8 ounces), divided
8 slices smoked bacon, cooked until crisp, cooled, and crumbled
(reserve rendered bacon fat)
1 medium red onion, diced
1 cup Japanese breadcrumbs (panko)
2 scallions, green tops only, cut into ⅛-inch thick slices

Preheat the oven to 400ºF
Place the pumpkin and potato cubes in a medium saucepan with enough cold water to cover
Add a large pinch of salt and bring to a boil
Reduce to a simmer and cook, uncovered, until the potatoes are tender when pierced with the tip of a small knife,
about 20 minutes
Drain in a colander, then return to the same pan (off the heat)
Add 3 tablespoons of the butter to the pan, and mash with a potato masher or pass through a food mill
Add the nutmeg and sage, then season to taste with salt and pepper
Whisk in the eggs, one at a time, until completely combined, then stir in half the cheese
Heat a medium sauté pan over medium heat; add 2 tablespoons of the reserved bacon fat and heat through
Stir in the onion and cook until tender and translucent, about 8 minutes
Butter the bottom of a 2-quart gratin dish.
Layer the sautéed onions on the bottom of the dish
Spread the pumpkin mixture evenly over the onions, then sprinkle the remaining cheese evenly over the top
Blend the remaining tablespoonful of butter with the breadcrumbs, green onion, and crumbled bacon; sprinkle evenly over the cheese mixture
Bake, uncovered, until the crust is light golden brown, about 30 to 45 minutes. If the crust is getting too brown, cover with aluminum foil to finish the cooking process; let stand 10 minutes before serving

Variation: Substitute acorn or butternut squash for the pumpkin.

Make It Ahead: Assemble the gratin through Step 6 up to 2 days in advance; remove from the refrigerator 30 minutes before baking.

Remove lid and sprinkle the cold butter and lard atop the flour mixture; pulse the food processor several times until the butter and flour are coated and the mixture resembles small peas. (the lard and butter must be cold when adding)

Once the mixture starts to form a small crumb and slightly coming up the sides of the bowl, slowly poor in the ice water and cider vinegar thru the feed tube with the motor running.
