Preheat oven to 400 degrees.
Go ahead and make your pie crust if you are making it from scratch.
Melt the butter either in a microwave-safe bowl in the microwave or on the stovetop and set it aside to cool.
In a medium mixing bowl, beat the eggs with a whisk by hand.
Add sugar and light corn syrup to the eggs and stir well.
Add melted butter (cooled down a little bit), pecans and vanilla.
Stir it all to combine well.
Pour the pie mixture into the unbaked pie shell.
Bake at 400 degrees for 10 minutes.
Then reduce the over to 350 degrees and continue to bake for another 30-35 mimnutes, until the middle of the pie is no longer jiggly.
Serve warm. Enjoy!
