While cheesecake might not have its roots in the South, it has certainly won over our Southern hearts, especially my husband’s! It’s his all-time favorite dessert, the one he requests every single year for his birthday. When we transitioned to a keto lifestyle, I knew I had to create a low-carb version that could stand up to the classic. After countless tests, this is it: a rich, velvety, and utterly decadent cheesecake with a crisp, nutty crust that has fooled even the most discerning dessert lovers. I promise, no one will ever guess it’s keto! We love it topped with a dollop of sugar-free whipped cream and a handful of fresh berries.
Ingredients
• For the Crust
• 1 cup / 112g finely ground blanched almond flour
• 1 cup / 120g raw pecan halves, finely crushed
• ½ cup / 100g granular erythritol
• ¼ cup / 57g salted butter, cubed
• For the Filling
• 5 (8-ounce) packages / 1130g cream cheese, softened
• 1½ cups / 180g confectioners’-style erythritol
• 4 large eggs, at room temperature
• 1 cup / 240g sour cream, at room temperature
• 1 tablespoon / 15ml freshly squeezed lemon juice
• 1 teaspoon / 5ml vanilla extract
Instructions
1. To Make the Crust
2. Preheat your oven to 375°F / 190°C. Prepare a 9- or 10-inch springform pan by greasing the bottom and sides with butter, or by lining the bottom with a parchment paper circle and greasing the sides.
3. In a medium bowl, combine the almond flour, crushed pecans, granular erythritol, and cubed salted butter. Use a fork or your fingers to mix until the are well combined and the mixture is crumbly.
4. Press the crust mixture evenly and firmly into the bottom of the prepared pan.
5. Par-bake the crust for 12 to 15 minutes, until the edges are golden brown.
6. Remove the crust from the oven and reduce the oven temperature to 325°F / 165°C. Allow the crust to cool completely on a wire rack while you prepare the filling.
7. To Make the Filling
8. In a large mixing bowl, use a hand mixer on medium speed to beat the softened cream cheese until it is completely smooth and fluffy, with no lumps.
9. With the mixer still on medium, gradually add the confectioners’-style erythritol and beat until it is fully incorporated and the mixture is smooth.
10. Add the room-temperature eggs one at a time, mixing on low speed just until combined. Be sure to scrape down the sides and bottom of the bowl after each addition.
11. Gently beat in the sour cream, followed by the lemon juice and vanilla extract, mixing on low speed just until combined. The final batter should be thick, smooth, and creamy.
12. To Assemble and Bake
13. Tightly wrap the outside of the cooled springform pan with one or two large sheets of heavy-duty aluminum foil. This creates a waterproof seal for the water bath.
14. Pour the cheesecake filling over the cooled crust and smooth the top with an offset spatula.
15. Place the foil-wrapped springform pan into a large roasting pan. Carefully pour hot water into the roasting pan until it reaches halfway up the sides of the springform pan.
16. Bake for 1 hour and 30 minutes, or until the edges are set but the center still has a slight jiggle. The top may be lightly browned.
17. Carefully remove the springform pan from the water bath and remove the foil. Let the cheesecake cool completely on a wire rack at room temperature.
18. Once cooled, cover the cheesecake and refrigerate for at least 8 hours, or preferably overnight, to allow it to fully set.
19. To serve, run a thin knife around the edge of the pan before releasing the springform latch. Slice and enjoy! Leftovers can be stored in an airtight container in the refrigerator for up to 5 days.

Pro Tips
• for a Perfect Cheesecake
• Room temperature are non-negotiable. Ensure your cream cheese, eggs, and sour cream are all at room temperature for a silky-smooth, lump-free filling that resists cracking.
• Don’t overmix after adding the eggs. Mix on low speed and only until just combined. Overbeating incorporates too much air, which causes the cheesecake to puff up and then crack as it cools.
• The water bath is your best friend. The steam creates a humid oven environment, allowing the cheesecake to bake gently and evenly. This is the number one trick for preventing cracks and achieving a creamy texture.
• Cool it down slowly. Abrupt temperature changes are a primary cause of cracks. After the baking time is up, turn off the oven, crack the door open, and let the cheesecake cool inside for one hour before moving it to a wire rack.
FAQ
Q: Why did my keto cheesecake crack
A: Cracks are often caused by overmixing the batter after adding eggs, using cold ingredients, or abrupt temperature changes. For a perfect, crack-free cheesecake, ensure your cream cheese, eggs, and sour cream are at room temperature, mix on low speed, and use the recommended water bath and slow cooling method.
Q: Is a water bath really necessary for this cheesecake
A: Yes, the water bath is the number one trick for a creamy, even-textured cheesecake. It creates a humid oven environment, which allows the cheesecake to bake gently and is the best way to prevent cracks from forming as it bakes and cools.
Q: Can I make this cheesecake ahead of time
A: Absolutely. This cheesecake needs to chill for at least 8 hours, but chilling it overnight is even better for the flavor and texture to fully set. It’s an ideal dessert to prepare the day before you plan to serve it.
