Pistachio Pastry Cream – Crème Pâtissière À La Pistache

Homemade pistachio pastry cream is indulgent and delicious. It has a rich crème pâtissière base, mixed with homemade pistachio paste and a hint of almond extract. It’s perfect to fill choux pastry, doughnuts, trifles, tarts and more. 

Crème Pâtissière À La Pistache

This recipe uses a quick pistachio paste, made from blanched pistachios brought together with a little water. It also has the addition of a little sugar and almond extract to enhance the pistachio flavor.

If you don’t want to make your own, you can buy pistachio paste too. That will make this custard smoother. Homemade pistachio paste will always have more texture to it than store-bought, but I personally love the texture of the flecks of pistachio in there. 

This is different from pistachio butter or pistachio cream. Pistachio butter is usually blended with a bit of oil to make it spreadable, while pistachio cream is often mixed with white chocolate.

Ingredients

First you make classic crème pâtissière, then a homemade pistachio paste. Here’s what you need. Find the ingredient amounts in the printable recipe card at the bottom of this post.

  • Whole milk: The base of the custard.
  • Sugar: Granulated white sugar.
  • Cornstarch: The thickener.
  • Large egg yolks: Brings a rich texture. Leftover egg whites can be saved and used for meringue!
  • Vanilla:  You can use a scraped vanilla pod, vanilla extract or vanilla bean paste. 
  • Salt: Flavor enhancer
  • Unsalted butter: The butter adds a little shine and richness and enhances the creamy texture.
  • Raw pistachios – Not salted or roasted
  • Almond extract – Optional, but it does a great job at bringing out the pistachio taste.

Note – You can also use a store-bought pistachio paste to save time. That will make a smoother custard.

Method

Pistachio Paste

Fill a medium pot with water and bring it to a boil. Once boiling, add shelled pistachios to the water and Let them boil for about 60 seconds. The goal here is not to cook the nuts, but to soften the skins so they can be easily removed.

While the pistachios are blanching, prepare a bowl of ice water. After the pistachios have boiled for a minute, drain them then immediately add them to the ice bath. This will stop the cooking process and cool them down quickly so they’re easier to handle.

Once the pistachios have cooled in the ice water for a couple of minutes, drain them and tip them onto a clean kitchen towel. You can use a kitchen towel to rub the skins off, or your hands to indiviually peel them.

My favorite way to do it is to take a second, dry kitchen towel and rub each pistachio indiviudally in that. The coarseness of the towel helps remove the skin.

After all the pistachios have been peeled, add them to a food processor and grind until they turn into a clumpy meal. This will take around 5-10 minutes. Stop and scrape down the sides of the bowl as necessary.

Once the pistachios have been ground down, add the powdered sugar to the food processor and continue to process.

With the food processor running, add water one tablespoon at a time until you reach a smooth, spreadable paste.

Don’t make it too thin, because you don’t want to add too much extra water to the custard later.  Add the almond extract, if using, and blend until fully incorporated. Scrape the paste into a bowl or jar and set aside.

Top Tips

It is crucial to cook the crème pâtissière long enough to deactivate amylase, an enzyme in egg yolks that can break down starch and cause the custard to become soupy as it cools.

Once the custard thickens and bubbles appear, you must cook and whisk continuously for a full minute. This will neutralize the amylase.

FAQS

Can you freeze pistachio pastry cream?

You can freeze it but upon thawing, it may separate and appear curdled. To fix this, you can reheat the thawed pastry on the stove until hot, and whisk until smooth. Or, heat a small portion in the microwave until hot and then whisk it into the rest of the custard until you get a smooth consistency

My pastry cream is too thin, how can I thicken it?

If your pastry cream is too thin after cooling, it may not have been cooked long enough. To fix it, you can return it to the heat and cook it, stirring constantly, until it thickens. However, pistachio pastry cream will always be thinner than regular crème pâtissière due to the addition of the pistachio paste. If you find it’s just too thin for your liking, you can make a cornstarch slurry (1 tbsp cornstarch mixed with 1 tbsp cold water). Whisk this into the pastry cream and return it to the heat and cook it a bit longer. Pour it into a bowl once cooked, cover with plastic wrap, cool it and then chill it. 

Can pistachio pastry cream be made ahead of time?

Yes, pistachio pastry cream can be made up to several days in advance. Cover it well with plastic wrap directly on the surface to prevent a skin from forming and refrigerated until needed.
