Once I sauté the garlic and wilt the spinach, I mix them with softened cream cheese and Parmesan until everything is smooth. This rich mixture becomes the heart of each puff, melding savory garlic with creamy cheese and earthy greens.
Next, I roll out my cold puff pastry on a lightly floured surface and cut it into squares about 3×3 inches. I spoon a generous mound of the creamy spinach mix into the center of each square, making sure not to overfill — this helps them bake without leaking.
I fold each pastry square into a triangle or pinch the corners to seal. Then I press the edges with a fork to lock in the filling and achieve that classic puff shape that looks impressive but is so simple to make.
Brushing each puff with beaten egg gives them a brilliant golden color when baked. I arrange them on a lined baking sheet and bake at 400°F until they’re puffed and golden — usually about 20 minutes.
