Substitute for Sour Cream in Cheesecake: Greek Yogurt

Plain, full-fat Greek yogurt is a reliable substitute for sour cream in cheesecake: use the same amount, cup for cup, for a creamy filling with a gently tangy flavor. This baked cheesecake pairs that simple swap with a graham cracker crust, and the slow cooling helps keep the center smooth as it sets.

Ingredients

2 cups (200 g) graham cracker crumbs
5 tablespoons (71 g) unsalted butter, melted
2 tablespoons (25 g) granulated sugar, for the crust
24 ounces (680 g) full-fat cream cheese, softened to room temperature
1 cup (200 g) granulated sugar, for the filling
1 tablespoon (8 g) all-purpose flour
3 large eggs (about 150 g without shells), at room temperature
1 cup (245 g) plain, full-fat Greek yogurt, at room temperature
1 teaspoon (5 ml) vanilla extract
1/4 teaspoon (1.5 g) fine salt
About 6 cups (1.4 L) hot water, for the water bath

Instructions

Prepare the pan and oven. Set a rack in the center of the oven and heat it to 325°F (163°C). Lightly grease a 9-inch (23 cm) springform pan. Wrap the outside of the pan with three overlapping layers of heavy-duty foil, bringing the foil up the sides to help keep water out of the crust. Start heating water for the water bath while you prepare the crust.
Make and bake the crust. Stir the graham cracker crumbs and the 2 tablespoons (25 g) sugar together in a bowl. Pour in the melted butter and mix until the crumbs look evenly damp and hold together when pressed. Tip the mixture into the pan and press it firmly across the bottom, making an even layer. Bake for 10 minutes, then set the pan on a rack to cool for 10 minutes while you make the filling. Keep the oven on.
Mix the filling gently. Beat the softened cream cheese on low speed until smooth, scraping the bowl and beaters as needed. Add the 1 cup (200 g) sugar and flour, then mix just until combined. Add the eggs one at a time, mixing on low after each addition only until the yolk disappears. Stir in the Greek yogurt, vanilla, and salt. Avoid whipping in lots of air; overbeating can cause the cheesecake to rise, crack, and sink as it cools.
Fill the pan and set up the bath. Pour the filling over the cooled crust and smooth the top. Put the foil-wrapped springform pan in a large roasting pan. Carefully pour hot water into the roasting pan until it comes about halfway up the outside of the springform pan. Keep water below the foil’s top edge, and take care not to splash any into the filling.
Bake until safely set. Bake for about 70 minutes. The edges should look set, with only a slight movement in the middle when the pan is nudged. Check the center with a food thermometer; for this egg-based dish, the USDA FSIS safe minimum is 160°F (71°C). If it has not reached that temperature, continue baking and check again after a few minutes. The center will firm further as it cools.
Cool slowly, then chill. Turn off the oven and leave the cheesecake inside with the door propped open about an inch for 1 hour. Remove the springform pan from the water bath, carefully peel away the foil, and cool the cheesecake on a rack at room temperature for 1 hour. Cover the pan and refrigerate for at least 6 hours, preferably overnight, before releasing the sides and slicing.

Tips

Choose the right yogurt. Plain, full-fat Greek yogurt gives the closest texture and richness to sour cream. Check the ingredient label for plain yogurt rather than vanilla or fruit-flavored varieties, which add sweetness and can bring extra liquid. A thick, strained yogurt is less likely to make the filling loose.
Use room-temperature ingredients. Let the cream cheese, eggs, and yogurt sit out until they are no longer cold, usually about 30 to 60 minutes depending on the room. Cold cream cheese can leave small lumps, and mixing harder to smooth them may add unwanted air to the batter. Do not leave perishable ingredients at room temperature for more than 2 hours.
Keep mixing low and brief. Smooth the cream cheese before adding the eggs, then mix just enough to combine each addition. Scrape the bowl so there are no unblended patches, but do not beat the finished batter until fluffy. The water bath and gradual cooling also help reduce abrupt temperature changes that can contribute to cracks.
Make a practical backup swap. If Greek yogurt is unavailable, use an equal amount of full-fat regular plain yogurt that has been drained in a fine-mesh strainer lined with a coffee filter or clean cheesecloth until thick. This concentrates it closer to Greek yogurt; using thin, undrained yogurt can make the filling softer and may lengthen baking time. Do not substitute sweetened yogurt.

Serving Suggestions

For clean slices, release the springform ring after the cheesecake is fully chilled. Warm a long, thin knife under hot water, wipe it dry, and cut one slice at a time, cleaning the blade between cuts. Serve the cheesecake cold or let each slice stand for about 10 minutes for a softer, less chilled texture. The mild tang from the Greek yogurt works well with fresh berries, sliced peaches, or a spoonful of fruit compote. Keep toppings separate until serving if you want the surface to stay neat and the fruit to retain its texture.

The cheesecake is rich on its own, so a small slice is satisfying after a meal. Coffee or unsweetened tea makes a simple accompaniment. If serving it at a gathering, put out a plain slice first, then offer toppings on the side so guests can choose without covering the whole cake.

Variations

Use sour cream instead. If you have sour cream after all, replace the Greek yogurt with 1 cup (245 g) sour cream. The result will be a little less thick before baking, but it is the direct equivalent in this recipe and keeps the familiar tang.

Add citrus. For a brighter flavor, add 1 teaspoon (5 ml) finely grated lemon zest to the filling with the yogurt. Zest adds fragrance without changing the liquid balance; avoid adding a large pour of lemon juice, which can alter the filling’s texture.

Change the crust. Use 2 cups (200 g) finely crushed digestive biscuits or vanilla wafer cookies in place of the graham cracker crumbs. Because cookies vary in sweetness and fat, keep the butter amount the same at first, then add a teaspoon more only if the crumbs seem too dry to press together.

Make a chocolate version. Fold 4 ounces (113 g) finely chopped, cooled bittersweet chocolate into the finished filling, or drizzle melted chocolate over the chilled cheesecake. For an even bake, use chocolate that is cool but still fluid when you fold it in, and stir gently rather than beating it into the batter.

Storage and Reheating

Refrigerate the cheesecake within 2 hours of baking or serving. Once it has chilled enough to cover without trapping much condensation, cover the pan tightly or transfer slices to an airtight container. It keeps for 3 to 4 days in the refrigerator. Keep fruit, sauces, and other toppings separate when possible, since they can make the surface wet or soften the crust during storage.

For longer storage, freeze the chilled cheesecake whole or in individual slices. Wrap it tightly in plastic wrap, then in foil or a freezer-safe container, and freeze for up to 2 months for best quality. Thaw it in the refrigerator overnight; do not thaw it on the counter. Cheesecake is usually served chilled, so reheating is not recommended. If a slice has been left out for more than 2 hours, discard it rather than saving it for later.

Frequently Asked Questions

Can I replace sour cream with Greek yogurt in cheesecake?
Yes. Use plain, full-fat Greek yogurt in the same quantity as the sour cream. For this recipe, that is 1 cup (245 g). It gives a similarly tangy filling, although the finished cheesecake may taste slightly less rich depending on the yogurt’s fat content.

Will the cheesecake taste like yogurt?
Usually, it tastes like cheesecake with a mild tang rather than like a bowl of yogurt. Cream cheese, sugar, and vanilla remain the main flavors. Choose plain yogurt and avoid strongly flavored or unusually sour varieties if you want the swap to be subtle.

Can I use nonfat Greek yogurt?
You can, but full-fat yogurt is preferable for this filling’s creamy texture. Nonfat yogurt may make the cheesecake taste leaner and can produce a slightly less smooth result. If it is the only option, use the same measured amount and do not add extra flour to compensate.

Can I use regular yogurt instead of Greek yogurt?
Yes, but drain plain, full-fat regular yogurt first so it is thick. Put it in a lined strainer over a bowl in the refrigerator and let excess whey drain until it resembles Greek yogurt. If you use it without draining, the filling may be softer and could take longer to set.

Why did my cheesecake crack?
Common causes include overmixing after adding eggs, baking it too long, or cooling it too quickly. Mix on low, use the water bath, and follow the gradual cooling steps. A small crack does not affect whether it can be served; cover it with fruit or a thin layer of topping if you prefer a smooth-looking surface.

How do I know when it is done?
The edges should look set and the center should move only slightly when the pan is gently nudged. Because this recipe contains eggs, also check the center with a food thermometer and make sure it reaches 160°F (71°C), the USDA FSIS safe minimum for egg dishes. It will become firmer during cooling and chilling.
