Flaky Buttery Pistachio Croissants (Printable)

Buttery croissants filled with rich pistachio cream, baked until golden and topped with chopped nuts.

# What You'll Need:

→ Pistachio Cream

01 - 3.5 oz shelled unsalted pistachios
02 - 2.8 oz unsalted butter, softened
03 - 2.8 oz powdered sugar
04 - 1 large egg
05 - 1 tsp vanilla extract
06 - 1 tbsp all-purpose flour
07 - Pinch of salt

→ Assembly

08 - 6 all-butter croissants, preferably day-old
09 - 3 tbsp simple syrup (optional)
10 - 1 oz chopped pistachios for garnish
11 - Powdered sugar for dusting

# How-To Steps:

01 - Preheat your oven to 350°F. Line a baking sheet with parchment paper.
02 - In a food processor, finely grind the pistachios. Add softened butter and powdered sugar; blend until creamy. Add the egg, vanilla, flour, and salt. Blend until smooth and well combined.
03 - Slice each croissant horizontally, leaving a small hinge so they don't separate completely.
04 - Brush the inside of each croissant with simple syrup to keep them moist during baking.
05 - Spread a generous layer of pistachio cream inside each croissant. Close and place on the prepared baking sheet.
06 - Spread a thin layer of the pistachio cream on top of each croissant. Sprinkle with chopped pistachios.
07 - Bake for 15–20 minutes, or until golden and the cream is set.
08 - Let cool slightly, then dust with powdered sugar before serving.

# Expert Advice:

01 -
  • The combination of flaky butter pastry and nutty cream creates layers of flavor and texture that feel luxurious without being pretentious
  • Using store-bought croissants means you can have bakery-quality results with about twenty minutes of actual work
  • The perfume that fills your kitchen while they bake is the kind of thing that makes family members wander in sleepy-eyed and asking what smells so good
02 -
  • Room temperature butter blends into the pistachio cream seamlessly, but cold butter will leave you with tiny lumps that never quite disappear
  • Do not overgrind the pistachios or they will turn into pistachio butter instead of the textured cream you want
  • Letting them rest for even five minutes after baking helps the cream set so it does not ooze out when you cut into them
03 -
  • Toast the pistachios in a dry pan for 3 to 4 minutes before grinding to deepen their flavor significantly
  • If the cream seems too thick, add a teaspoon of milk to reach spreadable consistency, but add it gradually
  • Freeze unbaked filled croissants for up to two weeks and bake straight from frozen, adding 5 minutes to the baking time
