Zingy and refreshing, this lemon low carb cheesecake is a heavenly creamy highlight to any meal. Your family will never guess it's sugar free! Keto, gluten free and diabetic-friendly.
I adore cheesecake. It's easy to make, looks impressive and cleanses your palate after a meal. And with a few simple tweaks, it can be sugar free and low carb!
Basically, you can make cheesecake so healthy you could eat it for breakfast (which I do whenever there's one in the house)!
Cheesecake comes in many wonderful varieties, from chocolatey to fruity. But I've got to say, this low carb lemon cheesecake is my new favourite.
The lemon juice and zest lend freshness to the velvety-rich yet curiously light filling and make the cake taste dreamy-creamy yet cleansing at the same time. This cake does not feel like the end of a meal. It feels like a new beginning!
Can you eat cheesecake on a Keto diet?
Absolutely! It's so easy to make low carb cheesecake. The main ingredient is normally cream cheese and cream such as double / heavy cream or sour cream. Both are perfectly Keto already.
For the crust, you simply use a grain free flour. Regular cheesecakes often have a crust made with Graham crackers or other sugary biscuits.
Apart from the sugar, these contain wheat, which out bodies convert into glucose (=sugar). By replacing this carb-heavy option with almond flour or coconut, your crust becomes nutrient dense and Keto.
Many low carb cheesecake recipes have a no bake crust which can become somewhat soggy. For this lemon cheesecake I have opted for a baked crust because I wanted the result to be crispy and light.
The cheesecake filling does not need to be baked and is set with gelatine. Friends, this recipe is the best of both worlds. I'm sure you'll love it!
How to make a lemon low carb cheesecake from scratch:
First, you mix the ingredients for the crust in a blender - almond flour, desiccated coconut and 1 egg. Press the dough into a tart or pie dish you've greased on the sides and lined with baking paper on the bottom.
If you feel adventurous, you could add teaspoon of ground ginger to the mix - ginger and lemon are flavour buddies.
I personally do not think the crust needs additional sweetener as the coconut has some natural sweetness to it. However, we're all different and you know yourself best. Do add a teaspoon of granulated or powdered erythritol if you feel it would work better for you.
If you have beans for blind baking, throw them on top of the crust before you put it in the oven. They prevent the bottom of the tart from rising up.
Another trick to prevent the crust base to bubble up is to get yourself a fork and poke holes in the unbaked crust.
After you bake your crust for about 20 minutes it will look like in the image above!
Tips for the low carb cheesecake filling:
The filling is a zingy lemony wonder that holds together with the help of gelatine. No need for any more baking - all it needs is some cooling time in the fridge!
You make it in a few simple steps:
- Blend the cream cheese, sour cream (works great here in place of the usual double / heavy cream), sweetener, lemon juice and zest until well-combined
- Dissolve your gelatine according to the manufacturer's instructions
- Add the gelatine to the filling
- Pour into the cooled tart base and refrigerate until set.
Top Tips: Let the gelatine cool down a bit before you mix it into the cream cheese/sour cream. If the temperature difference is too great it might end up lumpy.
Don't omit the lemon zest - it really makes the recipe. And as with the crust, adjust your sweetener to taste.
Here's how you can customise this recipe:
1.) You could use a muffin tin to make individual mini cakes
2.) Replace the lemon with lime and have yourself a sugar free key lime pie
3.) Skip the baking and make a no bake crust. Use the same amounts of almond flour and coconut, but replace the egg with ¼ cup of coconut oil. For this, use a springform (line it with baking paper) and spread the crust mix only on the bottom and not the sides.
4.) Make individual mini low carb cheesecakes in a muffin tin. To release those out of the tin with ease, use paper cups or freeze them for a couple of hours so they are nice and firm and pop out of the tin without you denting them.
5.) If you don't like the idea of gelatine, you can use very well-whipped double / heavy cream or whipped coconut cream (use only the firm parts from your can of coconut milk) instead of the sour cream. They will set without gelatine.

For the base
For the filling
- 300 g / 10.5 oz cream cheese
- 300 g / 10.5 oz sour cream
- 1 lemon, zest and juice
- 2 tablespoon powdered sweetener (or more, to taste)
- 12 g / 1 pack gelatine
- Preheat your oven to 180 Celsius / 356 Fahrenheit. Line the bottom of a tart/pie dish with baking paper and grease the sides.
- In a blender or with a hand mixer (use a tall jug), blend the ingredients for the tart base until they resemble sticky crumbles and the coconut is starting to release its oils.
- Press the dough into a tart or pie dish with your fingers. My dish measured 22 cm at the bottom and 26 cm at the top.
- Bake for around 20 minutes until the tart crust is lightly browned.
- Remove from the oven and let it cool down. Then remove tart base from the pan.
- Mix the cream cheese, sour cream, sweetener, lemon juice and zest in a bowl until smooth.
- Dissolve your gelatine according to your manufacturer's instructions (I dissolved mine in a few tablespoons of hot water) and add to the filling mix. Blend and fill into the tart base.
- Cool the tart in the fridge until set, a minimum of 2 hours or overnight. Decorate with more lemon zest or to your liking.
