If there’s one thing about me, it’s that I love frangipane. Like if it were my last day on earth, I would want to eat anything with frangipane. I adore it so much that I’ve developed several frangipane-forward dessert recipes that you all have LOVED (all at the bottom of this post) – they collectively have more than 200 reviews on the site and more than 2M views on TikTok and Instagram.

And I have had pistachio frangipane in my head for a while. So I am STOKED to share this recipe for pistachio croissants with you. It is SO easy – you don’t need a hand mixer, and you can use store bought croissants.

Pistachio croissants have a delicious salty-sweet flavor. They are SO incredible. Just look at the text my neighbor sent me when I dropped off pistachio croissants.

This post is all about a BANGIN’ pistachio croissants recipe.

Pistachio Croissants

What are pistachio croissants?

Pistachio croissants are buttery croissants that have a pistachio filling. There are two kinds of pistachio croissants:

• Pistachio cream croissants: croissants filled with a light pistachio pastry cream. This is the kind of pistachio croissant most common at bakeries. It’s more complicated to make since you need to make pastry cream. IMO, pistachio cream croissants are less tasty than frangipane croissants.

• Pistachio frangipane croissants: croissants with pistachio frangipane (pistachiso, butter, sugar, eggs, vanilla) in the middle. The filling is more gooey and fudgy.

For this recipe, we are making pistachio frangipane croissants. They’re easier and quicker to make than pistachio cream croissants, and IMO are WAY more delicious.

Ingredients

These pistachio croissants use just 7 ingredients:

• Store-bought croissants: ideally 1-3 days old, so they truly soak up our delicious filling

• Unsalted butter: butter is a key flavor in these croissants, so opt for the best quality butter you can. Cabot is a quality, affordable butter in Brooklyn where I live.

• Granulated sugar

• Egg: we just need one egg for this recipe, two if you’re doubling it!

• Vanilla extract

• Salt

• Roasted and salted shelled pistachios: just one bag will work. You want to make sure they’re roasted and salted, as that is KEY to the flavor of the recipe.

How to make pistachio croissants

1. Make the simple syrup. We use simple syrup to soak the croissants so they get that crispy exterior and nice and are nice and soft inside. To make simple syrup, you’ll combine equal parts water and sugar in a pot over low to medium heat and stir until the sugar dissolves. You can also do this in the microwave in 30-second bursts. Set aside to cool while you prep the rest of the croissants.

2. Make the pistachio frangipane. You’ll pulse pistachios briefly in a food processor or NutriBullet (I use my Ninja blender) until they are finely ground to make pistachio flour. Be careful not to over-pulse or you’ll get nut butter. You’ll then mix the butter and sugar together, stir in the egg and vanilla extract, and then stir in the ground pistachios and salt. Boom, you just made frangipane!

3. Now you’re ready to assemble the pistachio croissants. Slice the stale croissants in half so they’re like a hamburger bun. Brush the simple syrup over the bottom half, then spoon on frangipane. Put the top on, brush with more simple syrup, spoon on a little more frangipane and a sprinkle of pistachios.

4. Bake on a baking tray until the tops of the croissants are golden brown.

Fresh vs Stale Croissants

You ideally want stale croissants when making pistachio croissants. Stale croissants are far easier to slice. Plus they soak up the syrup and frangipane better since they’re dry and searching for moisture.

That said, you can use fresh croissants. They’ll just be a little bit more difficult to cut and work with!
