America’s favorite pumpkin puree is actually made from squash, so why not turn to the earthy sweetness of fresh butternut squash to make this recipe from Stella Parks
1 whole medium butternut squash (about 7 inches long and 4 inches across at the base; at least 24 oz.)
1⁄2 cup (4 oz.) light brown sugar, packed
1 tbsp. vanilla extract or bourbon
1 1⁄2 tsp. ground ginger
1 1⁄2 tsp. ground cinnamon
1⁄4 tsp. grated nutmeg, plus more to garnish if desired
1⁄4 tsp. Diamond Crystal kosher salt (half as much if iodized)
1⁄8 tsp. ground cloves
2 tbsp. (1 oz.) unsalted butter, melted
3 whole large eggs, straight from the fridge
2 cups whipped cream (optional)
1 cup (5 oz.) crushed toffee bits (optional)
Prepare the squash puree: Adjust oven rack to lower-middle position and preheat to 400°F. Split the squash lengthways, scoop out the seeds, and place cut side down on a foil-lined aluminum baking sheet. Roast until fork-tender, about 45 minutes. When the squash is cool enough to handle, use a large spoon to scrape out the pulp. Pulse in a food processor until smooth, or rub through a double-mesh sieve. Measure out 14 ounces (13⁄4 cups) squash puree. Use warm, or refrigerate in an airtight container for up to 1 week.
Make the pie: Adjust oven rack to lower-middle position and preheat to 375°F. In a medium bowl, whisk the squash puree, condensed milk, brown sugar, vanilla, ginger, cinnamon, nutmeg, salt, cloves, butter, and eggs until smooth. Pour into the baked crust, place on an aluminum baking sheet, and bake until the custard has puffed into a gentle dome, about 25 minutes. Reduce oven temperature to 350°F and continue baking until the custard is firm around the edges but still wobbly in the very center, about 25 minutes more (200°F; 210°F if the probe touches the crust). Let cool at room temperature until the custard is set, about 2 hours. Cut the pie with a chef’s knife. If you like, serve with dollops of whipped cream and a sprinkling of crushed toffee (if using). Wrapped in plastic, leftovers will keep for up to 4 days at room temperature.
