Spinach puffs are flaky, golden pastry parcels filled with spinach, cheese and a little seasoning; this version is a practical home recipe for anyone searching for spinach puffs at Choa Chu Kang. They are easy to prepare with frozen puff pastry and make a handy snack or party bite, though they are not tied to a particular Singaporean regional tradition.
Ingredients
- 10 oz (280 g) frozen chopped spinach, thawed
- 1 sheet frozen puff pastry, about 9 oz (255 g), thawed according to package directions
- 4 oz (115 g) cream cheese, softened
- ½ cup (50 g) finely shredded mozzarella
- ¼ cup (25 g) finely grated Parmesan
- 2 tablespoons (30 g) finely chopped yellow onion
- 1 small garlic clove, minced
- ¼ teaspoon fine salt
- ⅛ teaspoon ground black pepper
- ⅛ teaspoon ground nutmeg, optional
- 1 large egg (about 50 g), beaten with 1 teaspoon (5 ml) water, for egg wash
- 1 teaspoon (5 ml) olive oil, for the pan
Instructions
- Thaw the pastry and spinach safely. Follow the pastry package directions; if thawing in the refrigerator, allow enough time for it to become flexible but still cool. Thaw spinach in the refrigerator or microwave, then drain it thoroughly. Heat the oven to 400°F (200°C), and lightly oil a baking sheet or line it with parchment.
- Remove excess moisture from the spinach. Put it in a clean kitchen towel or several layers of paper towel and squeeze firmly over the sink. Keep squeezing until it no longer releases much liquid. This is important: watery spinach can make the pastry soggy and cause the filling to leak.
- Make the filling. In a medium bowl, mix the cream cheese, mozzarella, Parmesan, onion, garlic, salt, pepper and nutmeg, if using. Stir in the squeezed spinach until evenly distributed. Taste a small amount and adjust the seasoning if needed.
- Prepare the pastry. Unfold the cool pastry sheet on a lightly floured surface. If it is stiff, let it sit briefly until it opens without cracking; if it becomes soft or sticky, chill it for 10 minutes. Cut it into 12 equal squares, about 3 inches (7.5 cm) each.
- Fill and seal. Place about 1 tablespoon (15 g) of filling in the center of each square, keeping the edges clear. Brush two adjoining edges lightly with the egg wash, fold the pastry over to form a triangle, and press the edges together. Crimp with a fork, then transfer the puffs to the prepared sheet with space between them.
- Brush and bake. Brush the tops with the remaining egg wash. Bake for 18–22 minutes, rotating the sheet once if your oven browns unevenly, until the pastry is puffed and deep golden. The filling contains egg wash on the outside only; it should be thoroughly hot in the center. If checking with a thermometer, egg dishes should reach the USDA FSIS safe minimum of 160°F (71°C).
- Cool briefly before serving. Let the puffs rest on the baking sheet for 5 minutes, then move them to a rack or serving plate. The filling will be very hot just out of the oven.
Tips
- Squeeze the spinach well. This is the biggest safeguard against a wet filling. If using fresh spinach instead, wilt about 10 oz (280 g) in a pan, cool it, and squeeze it dry before chopping; its volume reduces considerably.
- Keep pastry cool. Warm pastry can tear and lose its flaky layers. Work quickly and refrigerate the cut squares for 10 minutes if they soften while filling them.
- Do not overfill. A level tablespoon is usually enough for a 3-inch square. Too much filling makes the seams difficult to seal and increases the chance of leaks.
- Make ahead without sogginess. Assemble the puffs, arrange them on a tray and freeze until solid, then move them to a freezer-safe container. Bake from frozen, adding about 5–8 minutes and checking for golden pastry and a hot center.
Serving Suggestions
Serve the puffs warm as a snack, appetizer or light lunch alongside a crisp green salad, sliced cucumber or tomato soup. A small bowl of plain yogurt with lemon and black pepper, marinara sauce or a mild chili dip makes an easy accompaniment. For a gathering, arrange them on a platter after their short cooling rest, and provide napkins because flaky pastry sheds crumbs.
Variations
For a sharper, saltier filling, replace the mozzarella with an equal amount of crumbled feta; reduce the added salt because feta is already salty. For a milder version, use more mozzarella and omit the nutmeg. You can also add 2 tablespoons (15 g) chopped sun-dried tomatoes or 2 tablespoons (15 g) finely chopped scallions, but avoid adding wet ingredients that could loosen the filling.
For smaller party bites, cut the pastry into 2-inch (5 cm) squares and use about 1 teaspoon of filling in each. Check them early, as they may bake faster than the larger triangles. If you need an egg-free finish, brush the tops with milk instead of egg wash; they may brown less deeply, but the pastry will still bake properly.
Storage and Reheating
Do not leave cooked puffs at room temperature for more than 2 hours. Refrigerate leftovers in a covered container within that time; they keep for 3–4 days. Reheat on a baking sheet at 350°F (175°C) for about 8–12 minutes, until hot throughout and crisp again. A microwave can warm them faster, but the pastry will soften. If reheating leftovers with a thermometer, bring the center to 165°F (74°C), the USDA FSIS recommendation for reheated leftovers.
To freeze baked puffs, cool them completely, freeze in a single layer, then transfer to a sealed freezer-safe container for up to 2 months for best quality. Reheat from frozen at 350°F (175°C) until hot in the center, usually 15–20 minutes; check early because ovens vary. Do not refreeze puffs that have been thawed at room temperature for more than 2 hours.
Frequently Asked Questions
Can I use fresh spinach instead of frozen?
Yes. Wilt about 10 oz (280 g) of fresh spinach in a pan, let it cool enough to handle, then squeeze out the liquid and chop it. Measure by weight before wilting; fresh spinach shrinks substantially as it cooks.
Can I prepare spinach puffs ahead of time?
Yes. Assemble them and refrigerate, covered, for up to 1 day before baking. For a longer make-ahead option, freeze the unbaked puffs as described in the tips. Bake chilled puffs straight from the refrigerator, allowing a few extra minutes if needed.
Why did the filling leak out?
The pastry may have been overfilled, the edges may not have sealed firmly, or the spinach may have held too much moisture. Keep filling away from the edges, press the seams together well and crimp with a fork. Chill soft pastry before baking if it is difficult to handle.
Can I make these without cream cheese?
Yes. Use ½ cup (120 g) thick ricotta, drained if watery, or ½ cup (75 g) additional shredded mozzarella. Ricotta gives a lighter, less tangy filling; extra mozzarella makes it stretchier and less creamy.
How do I know when the puffs are done?
Look for pastry that has risen and turned a deep golden color, usually after 18–22 minutes at 400°F (200°C). If you want to check the center with a thermometer, the egg-containing dish should reach 160°F (71°C); avoid measuring only the hot pastry edge.
Can I cook them in an air fryer?
Usually, yes, if the air-fryer basket fits the puffs without crowding. Try 350°F (175°C) for about 10–14 minutes, checking for golden pastry and a hot center. Air fryers vary, so use the first batch to establish the timing for your model.
