1-First Step: Preheat and prepare the pan Start by preheating your oven to 350°F (175°C) and position the rack in the lower-middle part of the oven. This gives the cheesecake steady heat from below without overbrowning the top too quickly. Use an ungreased 9-inch springform pan for best results. Before mixing anything, set up your roasting pan for the water bath and wrap the bottom of the springform pan in foil after the crust is baked. Having everything ready now makes the process smoother later.

2-Second Step: Make the crust In a bowl, mix the 1 and 3/4 cups graham cracker crumbs with 1/4 cup granulated sugar. Stir in the 5 tablespoons melted unsalted butter until the mixture looks sandy and holds together when pressed. Press the crumbs firmly into the bottom of the pan in an even layer. Bake the crust for 10 minutes. This short bake helps it stay crisp under the filling. After it comes out of the oven, wrap the outside bottom of the pan tightly in foil so the water bath does not leak into the cheesecake.

3-Third Step: Build the lemon sugar Place the 1 tablespoon lemon zest and 1 and 1/4 cups granulated sugar in a food processor or blender. Pulse a few times so the lemon oils soak into the sugar. This is one of the best tricks in the whole recipe because it makes the lemon taste stronger and more fragrant. Small step, big payoff: pulsing zest with sugar spreads the citrus flavor through every bite.

4-Fourth Step: Make the filling In a large mixing bowl, beat the 32 ounces softened cream cheese with the lemon sugar until smooth. Scrape the bowl as needed so no lumps remain. Then add the 1/2 cup lemon juice, 1/3 cup sour cream or plain yogurt, and 1 teaspoon vanilla extract. Mix until combined. Next, add the 3 large eggs one at a time, mixing gently after each addition. Stop as soon as the batter comes together. Overmixing after the eggs go in can add too much air, which may lead to cracks later.

5-Fifth Step: Fill the crust and set up the water bath Pour the cheesecake batter over the warm crust and smooth the top with a spatula. Place the springform pan inside a larger roasting pan. Carefully pour in enough boiling water to come about 1 inch up the sides of the springform pan. This water bath helps the cheesecake bake gently and evenly. If you prefer, you can place a separate pan of hot water on the rack below the cheesecake to create steam instead. That method is useful if you want to avoid direct water contact, but the traditional bath gives the steadiest result.

6-Sixth Step: Bake until just set Bake the cheesecake for 55 to 70 minutes. The edges should look set, while the center should still jiggle slightly when you gently move the pan. If the top starts browning too quickly, loosely cover it with foil. Do not wait until the center is completely firm in the oven. A slight wobble is exactly what you want, because the cheesecake finishes setting as it cools.

7-Seventh Step: Cool slowly Once the bake time is done, turn off the oven and crack the door open. Leave the cheesecake in the water bath for 1 hour. This gradual cooling helps prevent sinking and cracking. After that, remove the pan from the water bath and let it cool on the counter until it reaches room temperature. Patience matters here. A slow cooldown gives you a smoother finish and a cleaner slice later.

8-Eighth Step: Add the lemon curd topping Spread about 3/4 cup cooled lemon curd over the top, staying away from the edges so it does not drip down the sides. The curd adds a glossy layer and a punch of lemon flavor that makes this dessert taste bakery-worthy. If you are making the lemon curd from scratch, it is a good idea to prepare it ahead so it has time to cool fully before you use it.

9-Ninth Step: Chill until fully set Cover the cheesecake loosely and chill it for at least 4 hours, though overnight is even better. This is the step that gives the cheesecake its firm, sliceable texture. The flavor also improves as the cheesecake rests in the fridge. If you are planning for guests, make it the day before. That way, all you need to do on serving day is garnish and slice.

10-Final Step: Finish and serve Remove the rim from the springform pan. Garnish with whipped cream, lemon slices, or fresh berries if you want a bright, pretty finish. For clean slices, dip a knife in warm water and wipe it dry between cuts. Store leftovers in the refrigerator for up to 5 days.
