My favorite part of this pistachio cheesecake is the combination of a biscuit crust and a baked cream cheese filling. Finely ground pistachios give it a nutty flavor and a lightly textured filling, with lemon zest for a fresh finish.

The recipe uses shelled pistachios, not pistachio pudding mix or sweetened pistachio spread. Grind the nuts finely and mix gently after adding the eggs to keep the filling smooth.

Plan for about 6 hours 30 minutes from preparation to serving, including cooling and at least 4 hours in the refrigerator. Making it the day before gives it plenty of time to chill.

Ingredients

For the Crust

• 200g digestive biscuits or graham crackers
• 100g unsalted butter, melted

For the Filling

• 500g cream cheese, softened
• 200g granulated sugar
• 200ml heavy cream
• 3 large eggs
• 1 teaspoon vanilla extract
• 1 cup shelled pistachios, finely ground
• Zest of 1 lemon

Optional Topping

• Whipped cream
• Chopped pistachios

Choose unsalted pistachios and full-fat cream cheese. The nuts are measured shelled, so remove any shells before measuring. Keep the filling ingredients separate from the optional whipped cream and chopped-nut topping.

Prepare the Pistachios and Lemon

Measure the cup of shelled pistachios before grinding them. A cup of whole nuts and a tightly packed cup of finely ground nuts do not represent the same amount, so keep the order consistent. Remove any stray shell pieces as you measure. The separate chopped nuts for the optional topping do not come out of the cup reserved for the filling.

Work in short pulses and look at the nuts between them. If fine crumbs collect beneath larger pieces, stop and stir the contents with the machine switched off, then pulse again. The goal is an even, fine meal that scatters from a spoon. A few tiny flecks will remain visible in the cheesecake; the filling is not meant to be completely free of nut texture.

Natural pistachios can give the filling a subtle color rather than a vivid green. Cream cheese and heavy cream lighten the mixture, while the nuts can add green and brown flecks. Do not judge the amount of pistachio by color alone or add extra nuts to chase a brighter shade. Keep the measured cup so the filling stays consistent with the recipe.

For the lemon zest, grate only the colored outer surface and turn the fruit as you work. Stop before reaching the thick white layer underneath, which can taste bitter. Fine zest blends through the cream cheese more evenly than long strips. This recipe uses the zest, so there is no need to squeeze lemon juice into the filling.

Have the pistachios ground and the lemon zested before you start beating the cream cheese. Set the measured sugar, cream, vanilla, and eggs nearby in the order they will be used. This helps you finish the filling without pausing midway to clean the grinder or search for a grater.

How to Make Pistachio Cheesecake

Use a 9-inch springform pan for easy unmoulding, mixing bowls for the crumbs and filling, and an instant-read thermometer to check the center. Have a food processor or grinder, a mixer, a spatula, baking paper, and a rimmed baking sheet ready.

Step 1

Heat a conventional oven to 325°F (160°C). Line the base of a 9-inch springform pan with baking paper and lightly grease the sides. Set an oven rack in the middle position.

Step 2

Crush the digestive biscuits or graham crackers into fine crumbs. Mix with the 100g melted butter until all the crumbs are evenly damp.

Step 3

Press the crumb mixture firmly into an even layer over the base of the prepared pan. Refrigerate the crust while you prepare the filling. If the pistachios are not already ground, pulse them briefly in a food processor until fine; stop before they become a paste.

Step 4

Beat the softened cream cheese and sugar on low speed until smooth, scraping the bowl. Mix in the heavy cream, vanilla, ground pistachios, and lemon zest. Add the eggs one at a time on low speed, mixing only until each is incorporated. Scrape the bowl again so no lumps of cream cheese remain.

Step 5

Spoon the filling onto the chilled crust and smooth the surface. Place the springform pan on a rimmed baking sheet to catch any butter that leaks from the base.

Step 6

Bake for about 45–60 minutes, starting to check at 45 minutes. The outer part should be set, with only a small area in the center that trembles gently rather than sloshing. For the egg filling, check that the center reaches 160°F (71°C) with an instant-read thermometer. If needed, continue in 5-minute intervals; the visual and temperature checks matter more than the clock.

Step 7

Turn off the oven and leave the door ajar for 30 minutes. Move the pan to a wire rack for about 30 minutes more, then refrigerate it; do not leave it out for more than 2 hours after baking. Chill for at least 4 hours, preferably overnight, until cold and firm. Cover once cold.

Step 8

Run a thin knife around the edge before releasing the springform ring. Keep the cake on its base or transfer it carefully to a serving plate. Add the optional whipped cream and chopped pistachios just before serving.

Step 9

Cut into 10 slices with a clean sharp knife, wiping it between cuts. Serve cold and refrigerate leftovers promptly.

Tips for a Good Texture

Stop grinding before the nuts turn oily. Short pulses give fine crumbs. Grinding continuously can make pistachio butter, which changes how the nuts mix into the filling.

Soften the cream cheese first. It should give slightly when pressed, without becoming warm or runny. Scrape the sides and base of the bowl before adding the eggs; it is harder to remove lumps later without overmixing.

Avoid whipping the filling. Low-speed mixing adds less air. Too much air can make the cheesecake puff up and then sink or crack as it cools.

Use the doneness checks together. A small central wobble can remain when the egg filling has reached 160°F (71°C). The cake firms as it chills, so do not wait for a dry, rigid center in the oven.

Check the Base and Filling Before Baking

Whether you choose digestive biscuits or graham crackers, crush them finely enough that the crust looks even when pressed into the pan. Break up any large pieces before adding the melted butter. Spread the mixture across the whole base first, then press with the bottom of a flat measuring cup, keeping the thickness similar in the center and around the edge.

Scrape beneath the mixer beaters and around the bottom of the bowl before the eggs go in. Small pockets of plain cream cheese can hide there even when the surface looks smooth. Once the nuts are mixed through, expect a lightly speckled filling rather than the glossy appearance of a plain cheesecake. Trying to beat away every fleck will only keep the mixer running longer.

After spooning the filling onto the crust, use the spatula to carry it gently toward the edges and level the top. Avoid dragging deeply enough to disturb the biscuit layer. Keep the pan centered on its rimmed baking sheet so it is straightforward to move into the oven without tipping the filling toward one side.

Serving and Make-Ahead Ideas

Chill the cake in its pan and decorate it after unmoulding. The whipped cream and chopped nuts are optional; plain slices let the pistachio flavor come through. For another flavored cheesecake, try Earl Grey cheesecake.

For a dessert table, add chocolate-covered strawberries alongside small slices. If you want a different seasonal bake, the pumpkin cheesecake bars are another make-ahead option.

Storage

Keep the cheesecake covered at 40°F (4°C) or colder and use within 3–4 days. Store it without the whipped cream topping if making ahead. Keep serving time at room temperature under 2 hours, or 1 hour if the temperature is above 90°F (32°C).

Frequently Asked Questions

Can I use pistachio cream instead of the ground nuts?

Sweetened pistachio cream contains different amounts of sugar and fat, so it is not a direct swap here. Use the listed shelled pistachios to keep this filling balanced.

Why did the top crack?

Overmixing, overbaking, or a sudden temperature change can cause cracks. Mix gently, check the center before the cake looks fully firm, and follow the gradual cooling step. A small crack does not stop you from serving the cheesecake.

Can I cut it before it has chilled?

Warm cheesecake is much softer and may not hold a clean slice. Leave it in the pan until it is fully cold and has had at least 4 hours in the refrigerator.
