Use gluten-free pie crust for a perfect base. 

Substitute regular flour with almond or coconut flour. 

Incorporate a mix of brown sugar and maple syrup for sweetness. 

Ensure the pecans are fresh and crunchy for the best texture. 

Add a pinch of sea salt to balance the sweetness. 

Opt for dairy-free butter if needed for a vegan version. 

Bake at a moderate temperature to avoid burning the crust.
