Pistachio Cream Croissants Recipe

Make the Pistachio Cream Croissants Recipe for flaky, nutty croissants filled with silky pistachio cream. Try it for brunch or dessert.

Ingredients

• 1/2 cup (120 ml) water
• 1/4 cup (50 g) granulated sugar, for the soaking syrup
• 1 teaspoon pure vanilla extract, for the soaking syrup
• 1 teaspoon orange blossom water or finely grated zest of 1/2 orange (optional), for the soaking syrup
• 1 cup (120 g) unsalted shelled pistachios, lightly toasted and completely cooled, for the pistachio cream
• 1/2 cup (50 g) blanched almond flour (finely ground almonds), for the pistachio cream
• 1/2 cup (100 g) granulated sugar, for the pistachio cream
• 6 tablespoons (85 g) unsalted butter, at room temperature, for the pistachio cream
• 1 large egg (about 50 g), at room temperature, for the pistachio cream
• 1 large egg yolk, at room temperature, for the pistachio cream
• 2 tablespoons (16 g) cornstarch, for the pistachio cream
• 1/4 teaspoon fine sea salt, for the pistachio cream
• 1 teaspoon pure vanilla extract, for the pistachio cream
• 1 teaspoon pistachio paste (optional, for deeper flavor and color)
• 1/4 cup (60 ml) heavy cream, at room temperature, for the pistachio cream
• 8 day-old all-butter croissants (about 60–70 g each)
• 1 large egg, at room temperature, for egg wash
• 1 tablespoon (15 ml) whole milk or heavy cream, for egg wash
• 1/3 cup (40 g) coarsely chopped unsalted pistachios, for topping
• 2 tablespoons (16 g) powdered sugar, for dusting

Instructions

Step 1: Make the soaking syrup

Warm water and sugar together until the sugar is fully dissolved, then bring just to a gentle simmer. Remove from heat, stir in pure vanilla and orange blossom water or a little grated orange zest if you like, and allow the syrup to cool completely until it is clear, slightly syrupy, and no longer steaming. This cooled syrup will be brushed onto the croissant crumb to add shine and gentle moisture without collapsing the layers.

Step 2: Grind the nuts and combine the dry mix

Place the lightly toasted, completely cooled pistachios in the food processor and pulse until they are finely ground but not oily. Add blanched almond flour, granulated sugar, cornstarch, and sea salt; pulse until the dry ingredients are evenly combined and the nut texture reads fine and powdery with tiny granular flecks of pistachio for structure.

Step 3: Emulsify into a silky pistachio cream

Add room-temperature butter to the ground nut mixture and process until a thick, cohesive paste forms, scraping down the bowl so the texture is uniform and glossy. With the motor running, incorporate the egg and egg yolk, vanilla and optional pistachio paste until the mixture is pale, airy, and creamy. Stream in the room-temperature heavy cream last so the cream becomes smooth, thick, and pipeable—soft peaks that hold their shape but are not stiff. Transfer to a piping bag or a matte spatula-ready bowl.

Step 4: Slice croissants and brush with syrup

Carefully slice each day-old croissant horizontally, leaving a small hinge so they open like books. Using a pastry brush, generously and evenly coat the interior crumb with the cooled soaking syrup—pleasantly moist, glossy, and tacky, but not soggy—so the layers stay intact and flavorful.

Step 5: Fill, finish, and bake until set

Pipe or spoon a thick, even layer of pistachio cream into the bottom half of each croissant, gently close them, arrange on a rectangular parchment-lined baking sheet, and lightly egg-wash the exposed tops for a glossy finish. Pipe a thin ridge or small dollop of extra pistachio cream along each top ridge, press on coarsely chopped pistachios so they adhere, then bake until the croissants are deep golden, the filling set, and the nut topping is lightly toasted. Let cool on the sheet for a short rest and dust with a fine veil of powdered sugar.

Step 6: Serve slightly warm on the baking sheet

Transfer the warm croissants back onto the same rectangular serving surface (retain the parchment-lined rectangular geometry), present them as a neat row so the glossy tops, scattered chopped pistachios and the faint powdered-sugar veil read crisply against the marble, and enjoy while the centers are just warm. Store leftovers in an airtight container and re-crisp gently before serving.

Notes

• Toast pistachios lightly and cool completely before processing to boost flavor.
• Chill the pistachio cream briefly if it becomes too warm while processing.
• Use day-old croissants for the best texture when soaking with syrup.
• Re-crisp leftovers in a 325 F oven for 5 to 8 minutes before serving.
• Freeze unbaked assembled croissants wrapped individually for up to 1 month.
