Ingredients
Method
- Prep your pan: Line the bottom of an 8- or 9-inch springform pan with parchment. Lightly grease the sides. This helps clean release.
- Make the crust (optional): Mix 1 1/2 cups almond flour, 3 tablespoons powdered sweetener, a pinch of salt, and 4 tablespoons melted butter or coconut oil. Press into the pan. Bake at 325°F (163°C) for 10–12 minutes until lightly golden. Cool fully.
- Soften the cream cheese: Leave 24 ounces (680 g) cream cheese at room temperature 45–60 minutes. Soft cream cheese blends smoother and avoids lumps.
- Whip the cream: In a cold bowl, whip 3/4 cup heavy cream to soft peaks. Set aside in the fridge.
- Mix the sweetener and lemon: In a small bowl, combine 3/4 cup powdered erythritol (or 2/3 cup powdered allulose for less cooling effect), 1 tablespoon finely grated lemon zest, and a pinch of salt. Rub the zest into the sweetener with your fingers to release oils.
- Beat the cream cheese: In a large bowl, beat cream cheese with the lemon-sweetener mix until smooth and fluffy, about 2 minutes. Scrape the bowl.
- Add flavor and richness: Beat in 1 teaspoon vanilla, 2 tablespoons lemon juice, and 1/4 cup sour cream or Greek yogurt until silky.
- For a baked cheesecake: Beat in 3 large eggs, one at a time, on low speed just until combined. Do not overmix. Pour over the cooled crust (or into a lined pan if crustless). Bake at 300°F (149°C) for 40–50 minutes until edges are set and center still jiggles slightly. Cool 1 hour, then chill at least 4 hours or overnight.
- For a no-bake set (gelatin option): Skip the eggs. Sprinkle 1 1/2 teaspoons powdered gelatin over 2 tablespoons cold lemon juice. Let bloom 5 minutes, then warm gently until dissolved (do not boil). Beat the melted gelatin into the cream cheese mixture in a thin stream. Fold in the whipped cream. Spread over crust or into the lined pan. Chill 6–8 hours until set.
- Fold in whipped cream: For both versions, gently fold the whipped cream into the filling at the end (after eggs for baked, after gelatin for no-bake) to keep it airy and creamy.
- Finish and chill: Smooth the top with an offset spatula. Refrigerate until firm. Run a thin knife around the edge before releasing the springform.
- Garnish and serve: Top with extra lemon zest curls, a light dusting of powdered sweetener, or a few raspberries. Slice with a hot, dry knife for clean edges.
What Makes This Recipe So Good

How to Store
- Refrigerate: Cover and chill up to 5 days.
The lemon flavor deepens on day two.
- Freeze: Freeze slices on a tray until solid, then wrap individually. Store up to 2 months. Thaw overnight in the fridge.
- Avoid condensation: Let the cheesecake sit at room temp 10–15 minutes before unwrapping to minimize moisture on the surface.
Health Benefits
- Low carb: Using almond flour and non-sugar sweeteners keeps net carbs low while delivering dessert-level satisfaction.
- Higher fat, steady energy: Cream cheese and heavy cream provide fats that help with satiety and can support steady energy on low-carb diets.
- Protein boost: Cream cheese, eggs (for the baked version), and Greek yogurt add a modest amount of protein.
- Vitamin C from lemon: Fresh lemon juice and zest offer a small dose of antioxidants and brightness without added sugar.
What Not to Do
- Don’t use cold cream cheese: It clumps and leads to a lumpy filling.
Room temperature is key.
- Don’t overbake: For the baked version, take it out when the center still wobbles slightly. Overbaking cracks and dries it out.
- Don’t swap powdered sweetener for granulated one-to-one: Granulated can stay gritty. Use powdered for a silky texture.
- Don’t skip chilling time: The cheesecake needs hours to set properly.
Rushing will ruin the structure.
- Don’t add too much lemon juice: Extra acid can loosen the filling. Stick to the measured amount and boost zest for more flavor.
Recipe Variations
- Meyer lemon twist: Use Meyer lemons for a sweeter, floral note. Reduce sweetener slightly if desired.
- Crustless mini cups: Spoon filling into silicone muffin cups and chill for easy fat-bomb portions.
Great for meal prep.
- Coconut-lemon: Add 1/2 teaspoon coconut extract and sprinkle toasted unsweetened coconut on top.
- Berry ripple: Swirl in a few teaspoons of mashed raspberries mixed with powdered sweetener before baking or chilling.
- Mascarpone blend: Swap 8 ounces of cream cheese for mascarpone for an extra-smooth, lightly sweet finish.
- Lemon curd layer (low carb): Spread a thin layer of low-carb lemon curd over the chilled cheesecake for extra tang.
FAQ
Can I make it completely no-bake?
Yes. Skip the eggs, bloom and melt the gelatin, and fold in whipped cream. Chill 6–8 hours until firm.
It slices cleanly and stays stable.
What sweetener works best?
Powdered erythritol blends or powdered allulose work well. Allulose tastes closer to sugar and has no cooling effect, but it’s slightly less sweet, so adjust to taste.
How do I prevent cracks in the baked version?
Use room-temperature ingredients, mix on low after adding eggs, avoid overbaking, and cool gradually. Running a knife around the edge after 10 minutes of cooling also helps.
Is almond flour crust necessary?
No.
It’s optional. The cheesecake holds together well without a crust and saves a few carbs per slice.
Can I use bottled lemon juice?
Fresh lemon juice and zest provide the best flavor. Bottled juice can taste dull or bitter.
If you must use it, add extra zest to brighten it up.
How many carbs per slice?
It varies by brand and whether you include a crust. As a general guide, a crustless slice made with erythritol often lands around 3–5 net carbs. Calculate with your exact ingredients.
Can I use low-fat cream cheese?
Full-fat cream cheese gives the best texture and sets more reliably.
Reduced-fat versions can be softer and slightly chalky.
Why is my filling grainy?
The sweetener may not have dissolved, or your cream cheese was too cold. Use powdered sweetener and fully softened cream cheese for a smooth result.
How long should it chill?
At least 4 hours for baked and 6–8 hours for no-bake. Overnight is ideal for clean slices and deeper flavor.
Can I add more lemon for extra tang?
Add more zest, not more juice.
Too much liquid can loosen the structure. Zest intensifies lemon flavor without affecting texture.
