This is the best keto cheesecake recipe! So rich and creamy, it will make you swoon at the first bite. With only 3g of carbs per slice, you can dig in and still manage your macros.
Preheat the oven to 300F and generously grease a 9-inch springform pan. Cut a circle of parchment to fit the bottom the pan and grease the paper. Wrap 2 pieces of aluminum foil around the outside of the pan to cover the bottom and most of the way up the sides.
In a large bowl, beat the cream cheese and butter for 1 to 2 minutes, until completely smooth. Then beat in the sweetener until well combined.
Add the sour cream, lemon zest, and vanilla extract and beat until smooth. Scrape down the beaters and the sides of the bowl as needed.
Add the eggs, once at a time, beating each until just barely combined. Pour into the prepared springform pan and smooth the top.
Set the pan inside a roasting pan large enough to prevent the sides from touching. Place the roasting pan in the oven and carefully pour boiling water into the roasting pan until it reaches halfway up the sides of the springform pan.
Bake 70 to 90 minutes, until the cheesecake is mostly set but still jiggles just a little in the center when shaken. Remove the roasting pan from the one, then carefully remove the springform pan from the water bath. Let cool to room temperature.
Run a sharp knife around the edges of the cake to loosen, the release the sides of the pan. Refrigerate for at least 4 hours before serving.
