Pre-heat oven to 375 degrees.
In a medium saucepan over medium heat, combine pumpkin, brown sugar, cinnamon, and ginger. Cook until sugar is fully dissolved and mixture is thick and shiny, 3-5 minutes.
Place mixture into mixer bowl. If using a stand mixer, fit with paddle attachment. Beat pumpkin mixture on low speed.
Add in evaporated milk and vanilla. Beat until mixture has cooled slightly.
Add in eggs, one at a time, until fully combined.
Pour mixture into prepared pie crust. Bake at 375 degrees for 50-60 minutes.
Watch pie carefully. It is done when the pie is gently wiggled and moves all together (no ripples). If your pie crust edges are getting too dark, you may need to cover the edges with aluminum foil.
Remove from oven and allow to cool completely. Enjoy!
