Can I make these pastries ahead of time?
Yes. Assemble the pastries, place them on a baking sheet, cover with plastic wrap, and refrigerate for up to 24 hours before baking. You can also freeze unbaked pastries for up to 3 months.
How do I prevent the pastries from becoming soggy?
Squeeze the thawed spinach very dry to remove excess moisture. Avoid overfilling each pastry, and bake immediately after assembly or refrigerate until ready to bake.
Can I use a different type of sausage?
Yes. Italian sausage, breakfast sausage, or plant-based sausage all work. Use pre-cooked sausage if available, or brown raw sausage before adding to the filling.
What size should each pastry be?
Cut each puff pastry sheet into 6–8 rectangles or squares depending on desired appetizer size. Smaller pieces are easier for serving at parties.
How do I know when they're done baking?
Bake until the pastry is golden brown and puffed, typically 15–20 minutes at 400°F. The egg wash helps achieve a glossy, golden exterior.
