Delicately crisp on the outside and sumptuously soft within, the Pistachoux is a celebration of refinement and indulgence. Inspired by the grand tradition of French pâtisserie, this elegant creation brings together the airy lightness of pâte à choux and the rich, nutty sophistication of pistachio in a harmony of textures and flavors.
Each piece is crafted with precision, beginning with a perfectly baked choux shell — golden, tender, and just the right balance of crunch and chew. The heart of the Pistachoux reveals a luscious pistachio cream, smooth and silky, offering an intense yet nuanced nutty note that lingers delicately on the palate. Often crowned with a glossy glaze or a subtle decorative crunch, it’s as pleasing to the eye as it is to the taste buds.
Ideal for refined tea times, celebratory tables, or as a signature treat for those with a taste for the exquisite, the Pistachoux is more than a pastry — it’s a moment of Parisian charm, bite after luxurious bite.

- 165 g unsalted butter
- 3 g fleur de sel
- 22 g sugar
- 214 g all-purpose flour (T55)
- 375 g whole eggs
Pistachio Pastry Cream
- 336 g semi-skimmed milk

- 74 g granulated sugar
- 80 g egg yolks
- 36 g cornstarch
- 186 g unsalted butter

Lemon Cream Insert
Heat the butter and granulated sugar in a saucepan. Once the mixture is smooth and fully melted, add the eggs, fresh lemon juice, and lime zest. Place over medium heat and cook, whisking continuously, until the mixture comes to a gentle simmer.
Immediately remove from the heat, stir in the gelatin mass, and blend the mixture using an immersion blender until smooth.
Pour the lemon cream into silicone half-sphere molds — slightly smaller than the choux shells — and refrigerate until set.
Lemon Confit
Wash the lemons thoroughly. Using a vegetable peeler, remove the zest, leaving behind as much of the white pith as possible (as it adds bitterness).
Place the zest in a small saucepan filled halfway with water and bring to a boil to blanch. Drain through a sieve and repeat the blanching process two more times — blanching three times helps preserve the aroma while removing bitterness.
Place the blanched zest back into a saucepan with the lemon juice and sugar. Simmer over medium heat for 40 to 50 minutes, until the mixture has reduced and thickened.
Add the lemon verbena leaves, then blend the mixture while still hot in a food processor until smooth. Be aware: this preparation is intensely tart and full of flavor. Use only a small amount in the center of each lemon cream insert.
Cocoa Streusel
In a mixing bowl, combine all the dry ingredients. Add the cold butter cut into small cubes, then rub everything together between your fingers until the mixture takes on a sandy texture.
Roll or press the streusel out into a thin layer on a baking sheet lined with parchment paper.
Bake at 150°C (300°F) for 20 minutes, or until crisp and lightly browned
Craquelin (Crispy Topping)
Mix the light brown sugar and flour with the softened butter. Do not whip or incorporate air — just mix until smooth.
Roll the dough out between two sheets of parchment paper to a thickness of 2 mm. Transfer to the freezer and let it firm up completely.
Once solid, cut out small discs that match the size of your piped choux buns.
Choux Pastry
In a saucepan, bring the milk, water, butter, fleur de sel, and sugar to a boil.
Remove from the heat and immediately add the sifted flour all at once. Stir vigorously with a spatula until the mixture comes together into a dough and pulls away from the sides of the pan.
Dry the dough (panade) over medium heat for about 1 minute while stirring constantly.
Transfer the dough to the bowl of a stand mixer fitted with the paddle attachment (or whisk). Mix on medium speed until the steam dissipates and the dough cools slightly — it should no longer release visible steam.
Incorporate the eggs one at a time, mixing well after each addition until the dough becomes smooth and pipeable.
Transfer the choux dough into a piping bag fitted with a 15 mm plain tip. On a baking sheet, pipe 6 lines of 4 choux buns each, touching one another.
Place a craquelin disc on top of each choux.
Bake in a deck oven at 210°C (410°F) for 20 to 25 minutes, until golden brown and well puffed.
Pistachio Pastry Cream
In a saucepan, heat the milk and heavy cream together.
In a bowl, whisk the sugar and egg yolks until pale and creamy, then add the sifted cornstarch and mix well.
Pour the hot milk mixture over the egg yolk blend while whisking, then return the mixture to the saucepan.
Cook over medium heat, whisking constantly, until thickened like a classic pastry cream.
Remove from the heat and stir in the butter, gelatin mass, and pistachio paste. Mix thoroughly until smooth.
Assembly
Carefully cut each line of baked choux two-thirds of the way up, creating a “lid.”
Place a spoonful of cocoa streusel inside the base of each choux, then add a small amount of pistachio cream.
Set a frozen lemon cream insert in the center of each choux bun.
Pipe the remaining pistachio cream on top and sprinkle with additional streusel.
Replace the lids and dust lightly with icing sugar to finish.

Questions & Answers (FAQ)
Q: Can I make the Pistachoux in advance?
A: Yes — partially. The lemon inserts, confit, and streusel can all be prepared up to two days ahead. The inserts can even be frozen. However, for optimal texture and freshness, the final assembly should be done the same day you plan to serve them.
Q: Can I substitute the pistachio paste?
A: If you don’t have pistachio paste, you can use praline or hazelnut paste, but keep in mind this will change the flavor profile completely. To stay true to the Pistachoux identity, try to use a 100% pure pistachio paste if possible.
Q: What if I don’t have silicone half-sphere molds?
A: You can use a mini muffin silicone mold or even freeze the lemon cream flat and cut out rounds using a cookie cutter. The goal is to have a gelled insert that holds its shape and creates a surprise element in the center.
Q: Can I freeze the Pistachoux?
A: You can freeze the unfilled choux pastry. Once assembled, freezing is not ideal, as it will compromise the texture. If you need to plan ahead, freeze the components separately and assemble the day you serve them.
Q: What’s the difference between streusel and craquelin?
A: Streusel is a crumble topping baked separately and used for crunch and contrast, while craquelin is a thin layer of dough placed raw on top of the choux before baking — it melts into a crisp, crackled surface.
Q: Can I make this recipe without a stand mixer?
A: Yes, but it will require more manual effort — especially when incorporating the eggs into the choux dough or finishing the creams. A whisk, some elbow grease, and patience will get the job done!
