I almost ate the whole tray. If you like spanakopita, you will love these little bits of goodness. They are also much easier to make than the traditional spanakopita with layers of phyllo and they taste just as good!
1 10-ounce package frozen chopped spinach, thawed
1/2 cup crumbled feta
1/4 cup minced onion
1 tablespoon olive oil
1 teaspoon chopped dill
1 teaspoon minced garlic
Kosher salt and freshly ground black pepper
2 large eggs
1 sheet frozen puff pastry (from a 17.3-ounces package), thawed, rolled out to a 12″ square, kept chilled
Squeeze out as much liquid from the thawed spinach until dry.
Mix spinach and next 5 ingredients in a medium bowl. Season to taste with salt and pepper. In a small bowl, beat 1 egg to blend; fold into spinach mixture.
Cut puff pastry into 3 equal strips. Cut each remaining strip into 3 squares for a total of 9. Grease muffin tin. Place a square in each muffin cup, pressing into bottom and up sides and leaving corners pointing up. Divide filling among cups. Fold pastry over filling, pressing corners together to meet in center. DO AHEAD: Spinach puffs can be assembled 3 hours ahead. Cover puffs and chill.
Beat remaining egg to blend in a small bowl. Brush pastry with egg wash (this will give the pastry a nice sheen). Bake until pastry is golden brown and puffed, about 25 minutes. Transfer to a wire rack; let puffs cool in pan for 10 minutes. Run a sharp paring knife around pan edges to loosen; turn out puffs onto rack to cool slightly before serving.
