Yes, you can. Though in my opinion, the version made with galette dough is better. Still, if you prefer the convenience of puff pastry you can follow the recipe exactly as is and use it instead of the homemade galette dough. The only difference would be the time of baking. Puff pastry bakes faster than pie crust so I recommend baking in a 425 F degree oven for 15-18 minutes or until the crust turns golden brown.
