Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

For the choux pastry:

• Water

• Unsalted butter

• All-purpose flour

• Eggs

• Salt

For the pistachio pastry cream:

• Whole milk

• Granulated sugar

• Egg yolks

• Cornstarch

• Unsalted butter

• Pistachio paste

• Vanilla extract

For the pistachio glaze:

• Powdered sugar

• Pistachio paste

• Milk or water

• Chopped pistachios (for garnish, optional)

Directions

1. Prepare the choux pastry:
   In a saucepan, heat the water, butter, and salt until the butter melts. Add the flour all at once and stir vigorously until the dough forms a ball and pulls away from the sides of the pan. Remove from heat and let cool slightly. Beat in the eggs one at a time until the dough is smooth and glossy.

2. Pipe and bake the éclairs:
   Transfer the choux dough to a piping bag fitted with a large round or star tip. Pipe 4–5-inch long strips onto a baking sheet lined with parchment paper. Bake at 375°F (190°C) for 30–35 minutes or until golden brown and crisp. Cool completely on a wire rack.

3. Make the pistachio pastry cream:
   Heat milk in a saucepan until steaming. In a separate bowl, whisk together sugar, egg yolks, and cornstarch. Slowly pour the hot milk into the egg mixture while whisking constantly. Return the mixture to the saucepan and cook over medium heat, whisking, until thickened. Remove from heat and stir in butter, pistachio paste, and vanilla. Cool completely before using.

4. Fill the éclairs:
   Make a small hole in the bottom or side of each éclair. Using a piping bag fitted with a small round tip, pipe the pistachio pastry cream into each éclair until filled.

5. Prepare the glaze:
   Mix powdered sugar with pistachio paste and just enough milk or water to reach a thick but spreadable consistency. Dip the tops of each éclair into the glaze and smooth with a spatula if necessary. Garnish with chopped pistachios if desired.

6. Chill and serve:
   Refrigerate éclairs for at least 30 minutes before serving to allow the filling and glaze to set.

Variations

Storage/Reheating

Store filled éclairs in an airtight container in the refrigerator for up to 3 days. For best texture, enjoy within 24 hours. The choux pastry may soften slightly over time due to the filling.
Do not freeze filled éclairs, as the pastry cream does not thaw well. However, unfilled choux shells can be frozen for up to 1 month. Reheat frozen shells in a 300°F (150°C) oven for 5–10 minutes to restore crispness before filling.

FAQs

What is the best pistachio paste to use for éclairs?

Use a high-quality pistachio paste with a high nut content and no added sugar or oils for the most authentic flavor.

Can I make the pastry cream in advance?

Yes, pistachio pastry cream can be prepared up to 2 days in advance and stored in the refrigerator.

Why did my choux pastry collapse?

This often happens when the éclairs are underbaked or removed from the oven too early. Make sure they are golden and firm before removing them.

Can I substitute almond paste for pistachio paste?

While almond paste can be used, it will significantly change the flavor profile. Pistachio paste is recommended for this recipe.

How do I know when the éclairs are fully baked?

They should be puffed, golden brown, and feel firm when tapped. Do not open the oven during the first 20 minutes of baking.

Can I use store-bought pudding instead of pastry cream?

While possible, it is not recommended. Homemade pastry cream provides the best texture and flavor.

What tip should I use to pipe the éclairs?

A large round or French star tip works best for creating classic éclair shapes.

How do I keep the choux pastry from becoming soggy?

Ensure the shells are completely cool before filling, and store them in a dry, airtight container until ready to use.

Can I flavor the glaze with something else?

Yes, you can use vanilla, citrus zest, or even a touch of almond extract to customize the glaze flavor.

How long can I leave éclairs out at room temperature?

Filled éclairs should not be left at room temperature for more than 2 hours due to the perishable filling.
