Portuguese tarts, or pastéis de nata, are flaky pastry shells filled with a smooth egg custard scented with lemon and cinnamon, then baked until their tops develop dark spots. They are associated with Portugal, especially Lisbon, and this home-style version uses store-bought puff pastry to make the layered shells manageable without sacrificing their crisp edges.
Ingredients
- 1 sheet all-butter puff pastry, about 10 oz (280 g), thawed but still cold
- ¾ cup granulated sugar (150 g)
- ⅓ cup water (80 ml)
- 1½ cups whole milk (360 ml), divided
- ¼ cup all-purpose flour (30 g)
- 6 large egg yolks (about 108 g)
- 2 strips lemon peel, each about 2 inches (5 cm) long, with as little white pith as possible
- 1 cinnamon stick, about 3 inches (7.5 cm)
- ⅛ teaspoon fine salt (about 0.7 g)
- ⅛ teaspoon ground cinnamon (about 0.3 g), optional, for serving
Instructions
- Make the syrup. Put the sugar, water, lemon peel, and cinnamon stick in a small saucepan. Warm over medium heat, stirring just until the sugar dissolves, then let the syrup bubble gently for 3 to 4 minutes. Take it off the heat and set it aside. It does not need to reach a candy-making temperature or become deeply colored; a short simmer gives it body without making the custard too sweet or thick.
- Thicken the milk base. In a medium saucepan, whisk the flour, salt, and about ½ cup (120 ml) of the milk until completely smooth. Gradually whisk in the remaining 1 cup (240 ml) milk. Set the pan over medium heat and cook, whisking constantly and scraping the corners, until the mixture thickens enough to coat the whisk, about 4 to 5 minutes. Remove it from the heat. Lift out and discard the lemon peel and cinnamon stick from the syrup.
- Combine the custard. Slowly pour the warm syrup into the thickened milk mixture while whisking. In a separate bowl, whisk the egg yolks until blended. Whisk a few spoonfuls of the warm milk mixture into the yolks to temper them, then gradually whisk the yolk mixture back into the saucepan. Return the pan to low heat. Stir constantly for 2 to 4 minutes, until the custard is smooth and slightly thicker. Check the center with a food thermometer: USDA FSIS guidance gives egg dishes a safe minimum internal temperature of 160°F (71°C). Do not let the custard boil, which can make the yolks curdle. Transfer it to a clean bowl and let it cool for 20 minutes, stirring once or twice so a skin does not form.
- Shape the pastry shells. While the custard cools, lightly flour the counter and unfold the cold pastry. If needed, roll it gently into a rectangle about 10 by 12 inches (25 by 30 cm), keeping it roughly ⅛ inch (3 mm) thick. Starting at a long edge, roll it snugly into a log. Wrap the log and chill it for 20 minutes so it firms up and is easier to slice. Meanwhile, heat the oven to 500°F (260°C), or to its highest setting if it cannot reach that temperature. Set a rack in the upper-middle part of the oven.
- Line the pan. Lightly grease a standard 12-cup muffin pan. Cut the chilled pastry log into 12 even rounds, about ¾ inch (2 cm) thick. Set one round in each cup with its spiral facing up. Dip your thumb in cold water, then press each round from the center outward, stretching the pastry up the sides to form a thin shell with a slightly thicker base. Keep the pastry just below the rim; avoid making holes in the bottoms. If it becomes soft or sticky, put the pan in the refrigerator for a few minutes before filling.
- Fill and bake. Whisk the cooled custard briefly to loosen it, then divide it among the pastry shells, filling each about three-quarters full. Bake for 12 to 14 minutes, checking from 10 minutes onward. The pastry should be deeply golden at the edges, and the custard should be set with characteristic dark brown blisters on top. Oven strength and pan material affect browning, so use the appearance as well as the timing; do not wait for every tart to become uniformly dark.
- Cool and serve. Set the pan on a heat-safe surface for 5 minutes, then loosen the tarts carefully with a thin knife or small offset spatula and transfer them to a rack. Let them cool for at least 10 minutes before eating: the filling is very hot straight from the oven and will settle as it cools. Dust lightly with ground cinnamon if you like. The shells are at their crispest on the day they are baked.
Tips
- Keep the pastry cold. Puff pastry rises best when its layers are still cool as they go into a hot oven. If the dough gets floppy while you shape the cups, chill the pan briefly instead of adding lots of flour, which can make the shells tough.
- Use a muffin pan if you do not own tart tins. Small Portuguese tart tins give a traditional shape and can produce more browned sides, but a standard muffin pan works well. The tarts may be slightly larger and less shallow, so check them near the beginning of the baking window.
- Whisk the custard steadily. Flour can form lumps if it meets hot milk too quickly, and egg yolks can scramble if they are added directly to a hot pan. Make a smooth cold slurry first, temper the yolks gradually, and keep the pan over low heat after adding them.
- Do not expect identical tops in every oven. The signature spots come from intense heat, but home ovens vary. If your oven browns unevenly, rotate the pan once near the end of baking. Avoid broiling the tarts to force spots, since the pastry can burn before the custard sets.
Serving Suggestions
Serve the tarts warm or at room temperature, when the pastry is crisp and the custard has had time to settle. A light dusting of cinnamon is traditional in many servings; a little confectioners’ sugar is another option, though the filling is already sweet. Pair them with espresso, strong coffee, or unsweetened tea to balance the rich custard. For a dessert plate, add fresh berries or sliced fruit on the side rather than piling them over the pastry, which can soften the crust.
Pastéis de nata are a natural choice for a coffee break, brunch table, or small dessert after a meal. They are rich, so one tart per person is usually a satisfying portion, but you can serve smaller pieces if you are offering several sweets. Arrange them shortly before serving instead of leaving them uncovered for hours; pastry absorbs moisture from the air and gradually loses its crunch.
Variations
Use a touch of vanilla. For a softer, more familiar custard aroma, add ½ teaspoon (2.5 ml) vanilla extract after the custard comes off the heat. Vanilla is optional rather than essential, and it will sit alongside the lemon and cinnamon rather than replace them.
Change the citrus. A strip of orange peel can replace the lemon peel for a rounder, sweeter fragrance. Remove it before combining the custard, just as you would the lemon. Avoid adding much pith, which can contribute bitterness.
Make a dairy-free version. Unsweetened, unflavored oat milk can replace whole milk in the same volume, though the custard will taste less rich and may set a little differently. Choose a product without added vanilla or strong flavors. The pastry must also be dairy-free if you want the whole batch to avoid dairy; check its ingredient label, since many puff pastries contain butter.
Use homemade laminated pastry. If you already have puff pastry made, use a sheet of similar size and thickness. Traditional-style dough involves more detailed lamination, but packaged puff pastry is a practical shortcut for home baking. It gives a crisp, flaky shell without requiring a separate dough-making and folding schedule.
Storage and Reheating
Let the tarts cool, then refrigerate them within 2 hours of baking because the filling contains eggs and milk. Store them in a covered container for up to 3 days. The pastry softens in the refrigerator, so these are best eaten soon after baking, but chilling is the right choice for leftovers rather than keeping them at room temperature overnight.
To bring back some crispness, heat refrigerated tarts on a baking sheet in a 350°F (175°C) oven for about 5 to 8 minutes, then let them stand briefly before serving. Check that reheated leftovers reach 165°F (74°C), the USDA FSIS temperature for reheated leftovers, using a food thermometer in the filling. Avoid reheating them repeatedly, which can make the custard rubbery and the pastry dry. Freezing is possible for up to 1 month, but the custard may become slightly grainy after thawing; thaw overnight in the refrigerator and reheat in the oven.
Frequently Asked Questions
Are Portuguese tarts the same as pastéis de nata?
Yes. Pastel de nata is the Portuguese name for an individual custard tart, and pastéis de nata is the plural. Pastel de Belém refers to the well-known Lisbon-area version associated with Belém; recipes and methods vary, and this accessible home version is not intended to reproduce a protected bakery formula.
Can I make the custard or pastry ahead?
You can make the custard up to a day ahead and keep it covered in the refrigerator. Before filling, whisk it until smooth and spoonable; if it is very firm, let it sit briefly at room temperature. You can also shape the pastry shells in the muffin pan and refrigerate them, covered, for several hours. For the crispest result, fill and bake close to serving time rather than storing unbaked filled shells.
Why did my pastry shrink or turn soggy?
Pastry can shrink if it is stretched hard while being pressed into the pan, or if it warms up before baking. Press it gently and chill the shaped shells if they feel soft. A soggy base can result from underbaking, a cool oven, or overfilling. Preheat fully, use the upper-middle rack, and keep the filling below the rim so the pastry has room to bake and puff.
Can I use whole eggs instead of yolks?
Whole eggs are not a direct swap in this recipe. Their whites add water and protein, changing the custard’s texture and making it less rich. For the intended smooth filling, use the six yolks listed. Save the whites in a clean, covered container in the refrigerator and use them in another recipe within 2 days, or freeze them for later use.
How can I tell when the tarts are done?
Look for browned, flaky pastry and custard that has puffed slightly, set around the edges, and developed dark spots. The centers may still tremble gently when the pan moves, but they should not look liquid. The custard is cooked to the USDA FSIS egg-dish minimum before it goes into the shells; the final bake browns the pastry and finishes the tarts. They firm further as they cool.
