Dreamy Portuguese Custard Tart

Featured in Irresistible Desserts.

This luscious Portuguese custard tart features a crisp, buttery puff pastry layered with smooth, vanilla-infused custard. Baked at high heat, the custard top develops signature caramelized spots, lending a rich, toasted flavor to each bite. Hints of citrus and cinnamon deepen the flavor, while chilling the pastry ensures perfectly tender, flaky layers. Serve dusted with powdered sugar or cinnamon for a delightful café-style dessert, best enjoyed slightly warm with a creamy center.

This dreamy Portuguese Custard Tart brings together creamy vanilla custard and flaky puff pastry in a way that instantly transports me back to the tiny Lisbon pastelarias where I first fell in love with these tarts The custard bakes up golden with those signature caramelized spots while the hint of citrus and cinnamon makes every bite completely irresistible

My very first attempt at these was on a rainy afternoon with friends and we devoured the whole tart in minutes Ever since this recipe has been the reason for so many impromptu coffee breaks and sweet celebrations

Ingredients

  • Puff pastry sheet: Choose a good quality all butter puff pastry for the flakiest base
  • Butter: For greasing the pan This helps your crust release easily
  • Whole milk: Gives the custard its signature body and silkiness Choose fresh milk whenever possible
  • Heavy cream: Adds extra richness and a velvety mouthfeel Go for cream with a higher fat content for the best results
  • Cornstarch: Makes the custard sturdy without making it heavy Look for lumps and dissolve them completely
  • Granulated sugar: Provides sweetness and helps caramelize the top Use superfine sugar if you prefer a smoother filling
  • Cinnamon stick: Infuses the custard with warm spice Break your stick to release more cinnamon oils
  • Lemon peel: Adds brightness and balances richness Try to cut just the colored zest to avoid bitterness
  • Large egg yolks: Create that classic creamy texture Fresh eggs with golden yolks work best
  • Vanilla extract: Rounds out the flavor with fragrant vanilla Always opt for pure vanilla
  • Powdered sugar: Optional for dusting Finishes the tart with a pretty look
  • Ground cinnamon: Optional for sprinkling A final nod to the spice in the custard

Step-by-Step Instructions

Prepare the pan:
Grease a nine inch tart pan with butter making sure to get all the corners This prevents sticking and makes unmolding easy
Line with pastry:
Roll out your puff pastry to fit the pan Press it gently but firmly into every curve of the pan and let a little extra hang over the rim to help with unmolding Place the lined pan in the fridge to keep the pastry cold
Make the custard base:
In a saucepan whisk together whole milk heavy cream and cornstarch until no lumps remain
Infuse and thicken:
Add the granulated sugar cinnamon stick and a strip of lemon peel Warm the mixture over medium heat whisking constantly until it thickens into a smooth custard Take your time here thickening can take about five to eight minutes
Remove aromatics:
Fish out the cinnamon stick and lemon peel as soon as the custard is thick to keep the flavors fresh
Temper the eggs:
Whisk the egg yolks in a bowl Slowly drizzle in a bit of the hot custard whisking all the time Then pour the egg mixture back into the saucepan This gentle step prevents scrambled eggs in your filling
Finish the custard:
Stir in vanilla extract Return to the heat for one to two minutes whisking continuously until your custard is lush and creamy
Fill and bake:
Pour the finished custard into the cold pastry shell Bake at four hundred seventy five degrees Fahrenheit for twenty to twenty five minutes You want the surface to develop dark caramelized spots and for the custard to be set with a slight jiggle
Cool and serve:
Let the tart rest for at least ten minutes so the filling sets a bit before slicing Dust with powdered sugar and cinnamon just before you serve

The aroma of cinnamon and citrus always fills my home with childhood comfort and I love watching faces light up with the first taste of that golden top One time my daughter declared it tasted like sunshine and I have never forgotten it

To store cover the tart tightly and keep it in the refrigerator It will stay fresh and creamy for up to two days For the ultimate texture reheat slices for just a few minutes in a hot oven to restore the crisp pastry

Ingredient Substitutions

If you do not have heavy cream you can use all whole milk for a slightly lighter filling For the citrus note orange zest works beautifully in place of lemon If you run out of cornstarch try an equal amount of custard powder or tapioca starch

01 1 sheet puff pastry, thawed if frozen
02 Butter, for greasing pan

→ Custard Filling

03 240 ml whole milk
04 240 ml heavy cream
05 3 tablespoons cornstarch
06 200 g granulated sugar
07 1 cinnamon stick or 0.5 teaspoon ground cinnamon
08 1 strip lemon peel or orange peel
09 4 large egg yolks
10 2 teaspoons vanilla extract

→ Garnishes (optional)

11 Powdered sugar, for dusting
12 Ground cinnamon, for dusting

Instructions

Step 01

Preheat the oven to 245°C. Grease a 23 cm tart pan or springform pan with butter.

Step 02

Roll out the puff pastry sheet to fit the prepared pan. Press gently into the base and up the sides, allowing excess to hang over the edges. Refrigerate while making the custard.

Step 03

In a saucepan, whisk together whole milk, heavy cream, and cornstarch until fully smooth.

Step 04

Add granulated sugar, cinnamon stick, and lemon peel to the saucepan. Place over medium heat, whisking constantly, until the mixture begins to thicken.

Step 05

Discard the cinnamon stick and lemon peel from the thickened mixture.

Step 06

In a separate bowl, whisk egg yolks. Slowly add a small amount of the hot milk mixture into the yolks, whisking to prevent curdling, then return the yolk mixture to the saucepan.

Step 07

Stir in vanilla extract. Cook over low heat for 1–2 minutes, stirring constantly, until custard is smooth and creamy. Remove from the heat.

Step 08

Pour the custard evenly into the chilled puff pastry shell. Bake for 20–25 minutes, or until the top is golden with dark caramelized spots and the custard is set but still slightly jiggly.

Step 09

Let the tart cool in the pan for at least 10 minutes. Dust with powdered sugar and ground cinnamon before slicing and serving.

Notes

  1. For distinctive caramelized spots on the surface, allow the tart to develop deep golden patches in the final minutes of baking.
  2. Experiment with orange or lime peel for a refreshing twist, or a dash of almond extract for subtle nuttiness.
  3. Serve warm for optimal creaminess, paired with whipped cream or vanilla ice cream if desired.
