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.
All you need to do is to replace the sugar in the filling with a natural sugar alternative such as erythritol, stevia or other popular sugar alternative such as Splenda.
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.
Baker's Tips:
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.

Ingredients
For the base
- 150 g / 1 ½ cup almond flour or ground almonds
- 70 g / ¾ cup desiccated coconut unsweetened
- 1 egg large
For the filling
- 300 g / 10.5 oz cream cheese
- 300 g / 10.5 oz sour cream
- 1 lemon, zest and juice
- 2 tbsp powdered sweetener (So Nourished) (or more, to taste)
- 12 g / 1 pack gelatine
Instructions
- 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.

Barbara T says
Delicious and worked well and even
the gelatine “behaved”. I wondered if you could use that tart crust with apple slices on it like for a French apple tart baking it at the same temperature?
Katrin Nürnberger says
Yes, I think that would work!
Rachel says
Hey! This looks amazing, I'm going to make it next weekend but can I check something - for the gelatine I've read a 12g sachet makes a pint of liquid so how much liquid should be added? Just want to make sure I do it right! Thanks 🙂
Katrin Nürnberger says
I just used a few tablespoons of hot water, just enough to dissolve it. Don't use any additional water. You need the gelatine to set the cream cheese and lemon juice mix.
Luca says
Hi, lovely recipe you have- especially for summer time.
Have you tried using xanthan gum as thickener in the filling?
Katrin Nürnberger says
I don't think that would work. You'd have to use too much of it and it would probably taste a bit slimy.
Nicola Davis says
Silly question is this nutrition per slice or for the whole pie?
Katrin Nürnberger says
Nutrition is per slice! 🙂
Julie Puttock says
Are you able to freeze this?
Katrin Nürnberger says
Yes, you can 🙂
Julie Puttock says
Oh yes... I am definitely making this at the weekend. You've just made my day. Thank you
deborah harper says
can i replace the sour cream with yoghurt or cream? thank you
Katrin says
I think maybe a mix of greek yoghurt and double / heavy cream would work as a replacement. That way you'll have a similar texture and fat content.
Ken Simpson says
This is a delicious low carb dessert. I made it just like your recipe called for and loved it . I may try the coconut butter instead of gelatin as you suggested. I'll let you know how that goes. It's hard to believe this is a low carb dessert.
Angela Henderson says
I made this yesterday and I really liked it. I used about 1 1/3 cup of 100% erythritol (the powdered kind) and added it to the filling. I made a slightly different base (1 1/2 cups almond flour, 4 tablespoons melted butter and 2 tablespoons erythritol & baked at 180C for 20 minutes.). It tastes deilcious. I think next time I will make a berry jam (with erythritol) and swirl it onto the top of the cake before letting it set.
thanks for sharing the recipe.
Katrin says
I love your idea of a berry swirl! Thanks for letting us know your tweaks 🙂
Jennifer says
I am allergic to coconut, can it be omitted or could I use something else? Thank you!
Katrin says
Yes, you can replace it with any ground nuts or seeds you like.
Melissa says
I made this yesterday. It is truly the first low carb recipe that is worth making. I did use Jello brand no sugar lemon Jello. I mixed it with 1 cup boiling water, stirred it and let the temp come down before making the rest. I did add lemon juice too. I made the no bake crust. It was AWESOME! I m thinking of other Jello no sugar flavors to use now. Thank you for the great recipe.
Katrin says
Melissa, I'm so glad the recipe worked out well! Thank you for taking the time to comment.
Angela Elliott says
Hi, can I use agar agar instead of the gelatine? How much would I use please?
Katrin says
Hi Angela, I haven't tried using agar agar myself, so unfortunately I cannot help here. I have heard though that it can be used as a substitute for gelatine.
Keith says
Why does the almond flour link to the Amazon USA site that does not ship to the UK. What is recommended to buy here in the UK.
Katrin says
Hi Keith, I normally use plain ground almonds for my recipes, which I buy from Waitrose or Sainsburys.
Sheila says
My son made this for my birthday while I 'advised'. Tasting the filling, we ended up using close to 1/3 cup of 1:1 sweetener (Swerve).
The crust is so good that I used it again yesterday in another recipe instead of the crust the recipe called for. My Blendtec doesn't like it and had a hard time blending it so next time I will try my magic bullet.
So creamy and lemony-I was in heaven eating this!
I made some sf whipped cream for the table to put on top of slices and really enjoyed that.
Thank you-this recipe is exactly what I was hoping for and then some!
Btw, son is 25, I only advised on sweetness and how to press the crust in.
Katrin says
Wonderful! And happy birthday to you!!
Lucy says
Hi, Do you reckon I could use a packet of sugar free jelly mix dissolved in a small amount of warm water in place of plain gelatine? Do you reckon it'd work?
Also, being in the UK, I only ever see cream cheese like philadelphia or supermarket own brand soft cheese... will this work for no bake? In the usa they have philly in a block which is for baking but i haven't seen it here.
Thanks!
Katrin says
Hi Lucy, I think the sugar free jelly mix should work, it's gelatine with a bit of taste added, isn't it? I always use the own brand full fat cream cheese from either Waitrose or Sainsburys. I find they are firmer than Philadelphia and work better for cheesecakes.
lucy says
Thank you so much for your reply! Much appreciated!
Monica says
Fantastica tu receta!Thank you,gracias,from Buenos Aires!

How exciting! Leave me a comment with feedback once you’ve made something
Barbara says
I only had limes in the house so used them instead. Wow. Loved the tart base (I added a tsp of monkfruit) - so delicious!
Katrin says
The crust is one of my favourites, actually. I use it in this chocolate tart recipe as well.
Sheila says
OMG this cake was such a treat! I had the whole family round yesterday and we all enjoyed it. My son even asked if he could take the two last slices home 🙂 Thank you for this recipe
Katrin says
Hi Sheila, I'm so glad you all liked it!
Sandra Maccagnan says
Do you offer dairy free cheesecake recipes? I like the no or low sugar options, so thanks for that. But i have both celiac disease and lactose intolerant so it's a challenge for me.
Thank You
Sandy
Katrin says
Hi Sandra, I haven't tried making a dairy free cheesecake, but it's a great idea. I guess I'd replace the sour cream with coconut cream or even better coconut yoghurt - there's a brand called coyo here in the UK which is delicious - and use some soaked cashews as well in place of the cream cheese. I'd change the quantities - maybe 3/4 coconut and 1/4 cashew. You could even use a flax egg (a couple of tbsp flax meal and water) in place of the egg in the crust to make it vegan.
