When these come out of the oven, the pastry has puffed around the spinach filling and the folded corners turn crisp and golden. Spinach Puffs are a handy little savory bite, but the filling needs a bit of attention: too much moisture can leave the bottoms soft instead of flaky. I like how the cream cheese gives the spinach a smooth base while crumbled feta brings a sharper, saltier edge.
Each puff starts with a square of cold puff pastry pressed into a muffin well, so the tin helps keep the shape neat while the pastry rises. The filling is quick to stir together, and the egg wash gives the tops an even golden finish. Make all 18 in two muffin tins, then let them rest briefly before loosening them; warm from the pan, the pastry flakes around a creamy, savory center.
Kitchen Note
Keep the puff pastry cold as you work with it. If the squares turn floppy before they reach the muffin wells, pause and chill them until they’re firm enough to handle cleanly.
Save these Spinach Puffs for your next appetizer spread: creamy spinach and feta tucked into crisp, golden pastry.
Why the feta lets you season this filling with a light hand
Feta brings plenty of its own salty tang, so the small amount of kosher salt in this filling is there to round out the spinach and cream cheese, not make the mixture taste sharply salty. That balance matters because these puffs are small: every bite has filling and pastry together, and there isn’t a big scoop of plain spinach to dilute the seasoning.
The black pepper adds a gentle savory bite, while just a touch of nutmeg gives the spinach mixture a warm, familiar note without making it taste like dessert. Stir everything until evenly combined, but don’t add extra salt before tasting the mixture. Feta varies in saltiness by brand, and the filling also gets wrapped in plain pastry. The best result is a filling that tastes pleasantly seasoned on its own, with the feta still easy to notice.
That same balance is why I keep the filling straightforward. Scallion and garlic add savory flavor without drowning out the spinach, and the creamy cheeses make the mixture feel rich without needing a sauce. In the baked puffs, the salty cheese and mild greens stay distinct rather than blending into a flat, overly salty filling.
What each ingredient brings to the spinach-and-feta filling
- Frozen chopped spinach — Chopped spinach distributes evenly through the filling, and frozen spinach is convenient to measure once thawed. Squeeze it very dry before mixing; fresh spinach isn’t a direct one-for-one substitute because its water content and volume change as it cooks.
- Cream cheese — Softened cream cheese blends smoothly with the spinach and helps the filling hold together. Let it soften enough to stir without lumps; a cold block makes it harder to combine evenly.
- Feta cheese — Crumbled feta gives the filling salty, tangy pockets and a crumbly contrast to the cream cheese. Pre-crumbled feta works, though larger pieces may need breaking up as you stir so they spread through the mixture.
- Scallions, garlic, and nutmeg — Thinly sliced scallions and minced garlic add savory depth, while the ground nutmeg supports the spinach’s mild flavor. Mince the garlic finely so no large, sharp pieces interrupt a bite.
- Puff pastry — Frozen puff pastry is what creates the flaky shell and defined cups. Thaw it until pliable enough to unfold, but keep it cold; pastry that gets warm and soft is harder to press into the wells neatly.
- Eggs — One egg goes into the filling, where it helps the mixture set as it bakes. The other is beaten with water for brushing over the pastry, giving the exposed surface a glossy, golden finish.
How to fill the muffin wells without losing those flaky layers
Stir the spinach filling until evenly mixed
Combine the thawed, squeezed-dry spinach with the softened cream cheese, feta, scallions, garlic, egg, salt, pepper, and nutmeg in a medium bowl. Stir until the cream cheese is worked through the greens and the feta is distributed rather than sitting in one clump. A few visible flecks of spinach and feta are exactly right. If you spot a pool of liquid at the bottom of the bowl, squeeze the spinach more thoroughly before filling the pastry.
Press the pastry into the greased tins
Heat the oven to 400°F and coat 18 wells across two 12-cup muffin tins with nonstick cooking spray. Cut each thawed, cold pastry sheet into 9 squares, then press one square into each prepared well. Ease the pastry down into the cup without stretching it thin at the bottom. Leave the corners extending above the rim; those are the pieces you’ll fold over the filling.
Divide the filling and bring the corners together
Spoon the filling evenly into the pastry cups, using about 2 tablespoons in each. Keep the filling below the pastry corners rather than piling it into a mound, which leaves room to fold the pastry over. Bring the corners together and pinch them lightly; there’s no need to twist or compress the tops tightly. A relaxed pinch lets the pastry puff while keeping the filling tucked inside.
Brush, bake, and rest before loosening
Beat the remaining egg with the water and brush it over the pastry. Bake the tins on the upper and lower racks for 18 to 22 minutes, switching and rotating the pans halfway through so they brown evenly. Look for puffed pastry with a golden-brown surface before taking them out. Let the puffs rest in the tins for 5 minutes, then loosen each one gently and serve warm.
Two ways to change the shape or pastry
Leave the tops open for spinach cups
For a more open presentation, press the pastry squares into the muffin wells and leave their corners unfolded instead of pinching them over the filling. The spinach-and-feta center stays visible, and you get more exposed pastry around the rim. Keep an eye on the color as they bake, since an open top won’t look exactly like a folded puff.
Use gluten-free puff pastry
For a gluten-free version, replace the regular puff pastry with two sheets of gluten-free puff pastry and leave the spinach filling unchanged. Gluten-free pastry can be more delicate to unfold and shape, so handle it gently and keep it cold while assembling. The flaky layers may be less pronounced, and bake to the same puffed, golden-brown visual cue.
Storage and Reheating
- Refrigerator: Store cooled puffs in a covered container for 3 to 4 days. The pastry softens in the refrigerator, though the filling keeps its creamy texture.
- Freezer: Freeze the baked puffs in a single layer until firm, then transfer them to a freezer-safe container for up to 2 months. Thaw them in the refrigerator before reheating for more even warming.
- Reheating: Warm them on a baking sheet in a 350°F oven until hot in the center, reaching 165°F. The microwave is quicker but makes the pastry soft instead of crisp.
