Set your oven to 350 degrees Fahrenheit. Let it warm up fully before you start mixing. Place your unbaked pie crust on a flat baking sheet. This makes it easier to move the pie later.

In a large bowl, whisk the three eggs gently. Add the granulated sugar and mix until combined. You want the mixture to look smooth and slightly pale. Do not over-beat the eggs here.

Pour in the dark corn syrup and melted butter. Add the salt and vanilla extract to the bowl. Whisk everything together until the liquid is very smooth. The dark syrup gives it a rich color.

Fold in the semi-sweet chocolate chips and chopped pecans. Use a spatula to make sure they are spread evenly. The chocolate will melt beautifully while the pie bakes in the oven.

Pour the mixture carefully into your unbaked pie shell. Smooth out the top so the pecans are level. Be careful not to overfill the crust to avoid messy spills during the baking process.

Place the baking sheet in the center of the oven. Bake for about 50 to 55 minutes. The center should be slightly jiggly but the edges should be set. The crust should look golden brown.

Remove the pie from the oven carefully. Place it on a wire rack to cool for two hours. This is very important. The pie needs time to set so it cuts into clean slices.
