Pistachio-Lemon Bars Recipe

ByElena Hart March 28, 2026March 28, 2026

Introduction

Pistachio-Lemon Bars are a refreshing twist on the classic lemon bar, featuring a buttery pistachio crust and a tangy, bright lemon filling. These bars offer a delightful combination of nutty crunch and zesty citrus, perfect for any occasion.

The image shows a tall stack of four square bars with two layers each: a thick, golden-brown crumbly base and a top layer of light greenish-yellow filling with whole pistachio nuts embedded, dusted with powdered sugar. Around the stack, there are more cut bars arranged flat, showing the same layered texture, and a small pile of whole pistachios on the right. The bars sit on a white marbled surface that has powdered sugar scattered around. The background is plain white, and the focus is on the texture and details of the bars.

Ingredients

1 cup all-purpose flour
1/4 cup confectioners’ sugar

1/4 teaspoon kosher salt
1/2 cup cold, unsalted butter, cut into small pieces

1/4 cup shelled unsalted pistachios, roughly chopped
2 eggs

1 cup sugar
1/2 teaspoon baking powder
2 tablespoons all-purpose flour

1 teaspoon grated lemon zest
4 tablespoons fresh lemon juice
1/3 cup shelled unsalted pistachios

Confectioners’ sugar, for garnish

Instructions

Step 1: Preheat the oven to 350°F (175°C). Line an 8-inch square pan with parchment paper, or if using foil, lightly butter it to prevent sticking.
Step 2: In a food processor, combine 1 cup flour, 1/4 cup confectioners’ sugar, and 1/4 teaspoon kosher salt. Pulse a few times to mix.

Step 3: Add the cold butter pieces and process until the mixture is well combined and crumbly.
Step 4: Stir in 1/4 cup roughly chopped pistachios by hand.
Step 5: Firmly press this mixture into the bottom of the prepared pan using the flat bottom of a glass or measuring cup. If the dough sticks, place a piece of parchment paper on top before pressing.

Step 6: Bake the crust for about 20 minutes or until lightly browned.
Step 7: While the crust bakes, whisk together the filling ingredients: 2 eggs, 1 cup sugar, 1/2 teaspoon baking powder, 2 tablespoons flour, 1 teaspoon grated lemon zest, and 4 tablespoons fresh lemon juice until smooth.
Step 8: When the crust is done, pour the filling evenly over it, then sprinkle 1/3 cup shelled pistachios on top.

Step 9: Bake for another 20 minutes, or until the filling is set and no longer jiggly.
Step 10: Let the bars cool completely in the pan. Once cooled, dust with confectioners’ sugar and cut into 2-inch squares to serve.

Tips & Variations

For a deeper lemon flavor, add a tablespoon of lemon juice to the crust mixture before baking.

Use roasted pistachios for a richer, nuttier taste.
If you prefer a gluten-free option, substitute the all-purpose flour with a gluten-free blend.
Chill the bars before cutting to get cleaner edges.

Storage

Store the pistachio-lemon bars in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate them for up to 5 days. Bring to room temperature before serving, or warm slightly for a fresh-from-the-oven feel.
