Preheat your oven to 275 degrees Fahrenheit.
Have your pie crust ready for filling.
Whisk eggs, yolks, and sugars together in a large bowl until creamy.
Add butter, pumpkin puree, and other liquids.
Mix thoroughly.
Strain the pumpkin mixture through a fine sieve into another bowl.
This removes any lumps for a smoother pie filling.
Pour the filling into your prepared pie crust.
Smooth the top with a spatula.
Make sure it's evenly spread.
Bake for about 1 hour or until the center is firm but still slightly jiggly.
Keep an eye on it!
