Preheat oven to 350 degrees.

Add the eggs to a medium bowl and beat them a little.

Add the Karo syrup, sugar, and vanilla extract and mix well.

Next, pour the melted butter into the bowl and mix well.

Add the pecans and mix them in.

Cover a cookie sheet with aluminum foil and place the frozen pie crust on top. Pour the pecan pie mixture into the pie crust and place it into the oven.

Bake for 60 to 70 minutes.

The pie is done when the center is still a little bit jiggly. The edges will be done.

Let the pie cool at room temperature for at least two hours.

After two hours serve the pie or refrigerate.
