Cut the squash in half and remove the seeds. Place on a parchment paper lined baking sheet. Roast for 30-40 mins until fork tender. Set aside to cool.
Once cooled, Add the squash to a bowl with eggs and brown sugar. Using a hand mixer, start to mix until combined. Then add cinnamon, nutmeg, cloves, ginger, heavy cream and vanilla extract. Continue to mix until well combined.
Preheat the oven to 400℉.
Roll out your pie dough to a 12 inch round (approximately). Add the dough to 9 inch pie baking dish. Cut the excess dough from the edges and save it, in case you have a little filling leftover. Pour the filling into the crust. Filling may be too much, so don't over fill it. I usually make mini pies with the leftover. Sprinkle the crumble on top of the pie.
Brush the edges of the crust with egg wash. Bake for 1 hour. You may need to cover the edges of the crust 30 mins in so it doesn't burn.
Allow to completely cool before cutting.
