Why This Recipe Works
- Easy to make: The crust and filling come together quickly with just a few tools. No mixer needed! A quick lemon curd and a food-processor crust make this super doable for a weeknight bake or weekend treat.
- Perfect anytime of year: With fresh lemon juice, honey, and vibrant pistachios, these bars are tailor-made for warmer weather or any time you want a burst of sunshine.
- Serve as snack or dessert: These bars are elegant enough for brunch or afternoon tea, but casual enough to serve at a picnic or BBQ. Win-win!
Ingredients
This recipe comes together with some pretty straightforward ingredients. Here’s what you will need:
- Lemons: There are lemon bars after all! Freshly squeezed is best! You will also need the zest. If you wanted to change it up, you can totally try using lime juice. It’ll just be a lime curd, and you’ll end up with Lime Bars, which will be equally delicious.
- Honey: Adds natural sweetness and complements the lemon beautifully. Maple syrup could work in a pinch.
- Eggs: You will need 2 large eggs and 3 yolks for this recipe.
- All-Purpose Flour: This recipe calls for all-purpose flour for the crust. It’s what I use in most of my dessert recipes, like my Blueberry Peach Galette and Frangipane Tart. You could use a one-to-one gluten-free replacement here.
- Unsalted Pistachios: The key here is to use unsalted nuts. If you were to use salted, the lemon bars may end up being a touch on the salty side. Pistachios can be expensive, so feel free to use almonds or even pecans instead.

How to Make This Pistachio-Lemon Bars Recipe
Step 1. Preheat Oven and Prepare Pan. Preheat your oven to 350°F / 175°C and line an 8-inch square baking pan with parchment paper.
Step 2. Make Curd Base. In a saucepan set over medium heat, combine fresh lemon juice, honey, fragrant lemon zest, whole eggs, yolks, and salt (Image 1). Whisk well until combined (Image 2).
Step 3. Cook the Curd. Cook, while stirring gently but constantly, until the mixture begins to bubble. Allow it to bubble for 15 seconds before removing from the heat. It should be thick enough to coat the back of a spoon (Image 3).
Step 4. Stir in Butter and Strain. Stir in the butter until melted and fully combined (Image 4). Strain the lemon curd through a fine mesh sieve and into a bowl to remove any solids (Image 5). Set the bowl aside.
Step 5. Make the Crust. Add the flour, pistachios, granulated sugar, powdered sugar, salt and baking soda to a food processor (Image 6). Pulse a few times to chop the pistachios a little and mix the dry ingredients.
Step 6. Add Butter. Add in the butter and pulse a few more times until it comes together in a crumbly dough (Images 7-8). It will be dry but should clump together if you press it in your hands.
Step 7. Form Base and Par Bake. Press 2/3 of the crust dough into the bottom of the lined pan in an even layer with a rubber spatula or the flat bottom of a glass (Image 9). Bake for 15 minutes in the preheated oven on the middle rack.
Step 8. Add Curd and Topping. Remove from the oven and spread the lemon curd evenly over the hot crust using an offset spatula (Image 10). Crumble the remaining dough on top (Image 11).
Step 9. Final Bake. Bake again for 20-25 minutes or until golden brown.
Step 10. Cool and Slice. Let the baked bars cool completely on a wire rack, then chill in the fridge for at least 2 hours before removing from the pan and slicing with a sharp knife (Image 12). Dust with powdered sugar just before serving, if you like!
Expert Tips
- Use fresh lemons: Bottled juice won’t cut it here. The fresh lemon zest and juice bring that irreplaceable brightness.
- Don’t skip the straining step: It ensures your lemon curd is silky-smooth, with no bits of cooked egg or zest.
- Chill time is key: Refrigerating the bars allows them to set properly and makes slicing much easier.
- Roast the pistachios first. If you purchased raw pistachios, you should dry roast them in a hot oven or in a hot pan lightly to bring out their flavor. They burn quickly, so do this carefully. I like to lay them out on a baking sheet and bake them at 350°F for just 10 minutes.
- Common pitfall: To avoid a dry crust, make sure your dough holds when pressed; if not, add 1-2 teaspoon of cold water.
- Extra flavor boost: Add a dash of vanilla extract or a pinch of cardamom to the lemon curd for a subtle twist.
- To get the cleanest cuts: wipe your knife with a towel to remove any stuck-on curd as you cut. You can also run the knife under hot water to warm it up before slicing.
