Unusual evening dress shirts is a playful name for a savory, shirt-shaped baked appetizer made from puff pastry, spinach, cheese, and roasted red pepper. The crisp pastry folds into a neat collar-and-cuff silhouette, making a shareable centerpiece for an evening gathering without requiring special baking skills.
Ingredients
- 1 sheet frozen puff pastry, about 10 oz (280 g), thawed according to package directions
- 1 tablespoon (15 ml) olive oil
- 1 small yellow onion, finely diced, about 1 cup (150 g)
- 5 oz (140 g) fresh baby spinach, roughly chopped
- 1 garlic clove, finely grated or minced
- 4 oz (115 g) cream cheese, softened
- 1 cup (100 g) shredded sharp cheddar cheese
- 2 tablespoons (30 g) finely grated Parmesan cheese
- 1/4 teaspoon (1 g) fine salt
- 1/8 teaspoon (0.5 g) black pepper
- 1/4 cup (35 g) roasted red pepper, patted dry and finely diced
- 1 large egg (about 50 g), beaten with 1 teaspoon (5 ml) water, for egg wash
- 1 teaspoon (3 g) sesame seeds, optional
- 2 tablespoons (30 ml) water, for sealing the pastry edges if needed
Instructions
- Heat the oven and prepare a tray. Heat the oven to 400°F (200°C). Line a large baking sheet with parchment paper. If the puff pastry is still firm, let it thaw until pliable but cold; warm pastry is difficult to shape and tends to lose its layers.
- Cook the vegetables. Warm the olive oil in a skillet over medium heat. Add the onion and cook for 4–5 minutes, stirring occasionally, until soft but not browned. Add the spinach and garlic. Stir for 2–3 minutes, until the spinach is wilted and its released liquid has mostly evaporated. Transfer the mixture to a plate and cool for 5 minutes.
- Make the filling. In a bowl, stir the cream cheese, cheddar, Parmesan, salt, and pepper together. Fold in the cooled spinach mixture and diced roasted pepper. The filling should be thick, not watery; if liquid pools in the bowl, drain it before assembling so the pastry stays crisp.
- Shape the shirt body. Unfold the pastry on a lightly floured surface and roll it gently into a rectangle about 10 by 12 inches (25 by 30 cm). Cut a 3-inch-wide (7.5 cm) strip from one short end and set it aside for the collar and cuffs. Place the remaining pastry on the lined baking sheet. Spoon the filling down the center third, leaving a 1-inch (2.5 cm) border at the top and bottom. Fold the long sides over the filling so they meet or overlap slightly. Brush the edges with a little water and press to seal.
- Add the collar and cuffs. Cut the reserved pastry strip into two small triangles for the collar and two short rectangles for cuffs. Arrange the triangles at the top of the filled parcel, points angled outward, and place a cuff at each lower sleeve edge. Trim excess pastry if necessary; small scraps can be baked alongside as decorations. Press joins gently, then brush the entire pastry surface with egg wash. Sprinkle sesame seeds over the body if using.
- Bake until golden. Bake for 20–25 minutes, rotating the tray once if your oven browns unevenly. The pastry should be puffed, deeply golden, and crisp on the underside. Let it rest on the tray for 8 minutes before slicing into six portions; the short rest helps the creamy filling settle and makes cleaner cuts.
Tips
- Keep the pastry cold. If it becomes soft or sticky while shaping, refrigerate the assembled pastry for 10 minutes before baking. Cold pastry puffs more reliably.
- Dry the filling well. Spinach and roasted peppers can release water. Cook off the spinach moisture and pat the peppers dry; excess liquid can make the bottom soggy or open the seams.
- Use a substitute thoughtfully. Frozen spinach works: thaw about 3 oz (85 g), squeeze it very dry, and use it in place of fresh. Monterey Jack can replace cheddar for a milder filling; feta adds a saltier, tangier flavor, so reduce the added salt.
- Make the design simple. The shirt shape is decorative, not structural. A sealed rectangle with pastry triangles for a collar is easier to handle than elaborate cutouts and bakes just as well.
Serving Suggestions
Serve the pastry warm as an appetizer or a light supper, with a crisp green salad dressed in lemon vinaigrette. A bowl of tomato soup or roasted vegetable soup makes it more substantial. For a party platter, cut it into narrow strips after resting and offer mustard, a mild tomato relish, or plain Greek yogurt with chopped herbs as dips. Because the filling is rich, fresh, acidic sides balance it better than another heavy cheese dish.
Variations
For a mushroom version, sauté 1 cup (100 g) finely chopped mushrooms with the onion until their liquid has evaporated, then proceed with the spinach. For a meat-free but sharper filling, replace the roasted pepper with 1/4 cup (35 g) chopped sun-dried tomatoes; drain oil-packed tomatoes well. You can also use Gruyère instead of cheddar for a nutty flavor, or add 1 teaspoon (2 g) chopped fresh thyme. Avoid adding raw vegetables or extra sauce, which can release moisture during baking.
Storage and Reheating
Let leftovers cool briefly, then refrigerate them in a covered container within 2 hours of baking. Keep for 3–4 days. Reheat portions on a baking sheet at 350°F (175°C) for 8–12 minutes, until hot throughout and crisp again; a microwave will warm the filling but soften the pastry. For food safety, USDA FSIS recommends reheating leftovers to 165°F (74°C), checked with a food thermometer. Do not leave the pastry at room temperature for more than 2 hours, or more than 1 hour when the temperature is above 90°F (32°C).
Frequently Asked Questions
Can I assemble the pastry ahead of time?
Yes. Shape and fill it, cover it loosely, and refrigerate for up to 8 hours before baking. Brush with egg wash just before it goes into the oven. If the pastry feels very firm from chilling, it can go straight into the preheated oven; allow a few extra minutes if needed.
Can I use store-bought puff pastry that is already rolled?
Yes. Use a sheet close to 10 by 12 inches (25 by 30 cm), trimming it to shape if needed. Keep it chilled until you are ready to assemble, and check the package for its thawing directions because brands differ.
Why did the bottom turn soggy?
The filling was likely too wet, the pastry was warm, or the oven was not fully heated. Cook excess moisture out of the spinach, drain the roasted pepper, keep the pastry cold, and bake on the center rack until the underside is browned.
Can I freeze the baked pastry?
Yes. Cool it completely, wrap individual portions airtight, and freeze for up to 2 months for best quality. Thaw overnight in the refrigerator and reheat in a 350°F (175°C) oven until hot throughout, reaching 165°F (74°C).
How can I tell when it is done?
Look for evenly puffed, golden-brown pastry, including along the bottom edges. The filling ingredients are already cooked or ready to eat, so the key is baking the pastry fully and heating the filling through rather than taking a temperature of the egg wash.
Can I make it without egg wash?
Yes. Brush the pastry lightly with milk or cream for color, or leave it plain. The finish will be less glossy, but the pastry will still puff. Skip sesame seeds if you need to avoid them.
