Want a truly delicious and tangy low carb lemon ice cream? Look no further than this delicious Lemon Curd Ice Cream recipe. All the great lemon flavor without the carbs. Sugar-free and keto-friendly.
This lemon ice cream recipe has been updated to be easier and better than ever! And I have a few tricks for keeping it soft and scoopable, even days later.
There’s no question that I get obsessed with certain foods from time to time. I like to say that it’s an occupational hazard of being a food blogger who really does dream about food all day. Like a catchy tune, sometimes a flavor or a food item will just get stuck on replay in my head, going around and around until I have to find a new way to use it. Lemon curd has been the tune I’m singing of late, ever since I made some for an Easter brunch with friends. It’s so sweet and tangy, and so…so…lemony, it just screams spring. But here in New England, we skipped over spring entirely and went straight into summer. So my head has also been playing the tune of ice cream and other frozen treats. It wasn’t much of a leap to combine the two and churn up some low carb Lemon Curd Ice Cream.
I’ve seen lemon ice cream made with lemon curd before on other blogs and food sites, and it was pretty easy to figure out how it should be made. Lemon curd takes a lot of eggs as it is, so I knew it wouldn’t be necessary to add more to create a custard-based ice cream. I also really wanted the tang of the lemon curd to come through and not get swallowed up by the cream and the sweetener. I’ve seen some recipes that add a lot more sugar after adding the curd, which is plenty sweet in my opinion. But I kept my additional sweetener to a minimum, to allow for a tangy, creamy frozen treat.
How To Make Lemon Ice Cream
- This recipe now uses my updated low carb lemon curd. And I have to say, it’s all the better for it. The new lemon curd uses whole eggs, so you won’t have any lonely and unused egg whites hanging around.
- Be sure to cook your lemon curd in a glass or ceramic bowl. I find that metal bowls react a bit with the lemon juice to leave a funny metallic tang.
- If you’ve ever made lemon curd before, you know that it’s about getting the eggs and yolks to just the right temperature so that they are cooked through. It will thicken up quickly and suddenly, so make sure you keep your eyes on it at all times!
- Let the curd cool in the fridge before mixing with the whipping cream. Cover it tightly with plastic wrap so it doesn’t develop a skin.
- Once your curd is nicely chilled, you just need to mix in the other ingredients and plop it into your ice cream maker!
Keeping Low Carb Ice Cream Soft
Okay guys, I have been messing around with ice cream lot this summer, trying to figure out the trick to keeping it soft. And I’ve found that my best trick is to use a combo of Swerve Sweetener and Bocha Sweet. Bocha Sweet is a sweetener derived from the kabocha squash, and it’s a pentose sweetener. Xylitol is also a pentose sweetener, so it appears to be similar to that although it’s not toxic to animals according to the website.
I would love to tell you that I am sold on Bocha Sweet as the perfect low carb sweetener. But I am not entirely. So far, it does not seem to affect my blood sugar that much and I have several diabetic readers who’ve recommended it to me and say it works for them. But for some people it can cause some severe stomach upset (at least according to the Amazon reviews!) and while I haven’t experienced that, I am reluctant to try it full strength. It’s also quite expensive – even more so than other low carb sweeteners.
It’s also not a perfect sugar replacement. I tried using it in some low carb meringues and they were a disaster! They never firmed up at all, staying sticky and gooey.
However, I am finding it useful in keeping keto ice cream scoopable and soft. I made one batch of vanilla with just Bocha Sweet and to be honest, it was almost TOO soft and slightly goopy. So then I tried a batch that was half Swerve and half Bocha Sweet and it was firmer but not rock hard. I am still playing with the ratios here but I think a 50/50 or even a 60/40 (in favour of the Bocha Sweet) seems to work well.
So for this keto lemon curd ice cream, I recommend one of two things. Either make your lemon curd with Bocha Sweet and then add some powdered Swerve when you add the whipping cream. Or vice versa: make your lemon curd with Swerve and then add Bocha Sweet as the additional sweetener. The first option will probably give you the softest results.
If you don’t have Bocha Sweet or prefer not to use it, your ice cream will freeze pretty hard but it will soften nicely with a few minutes on the counter. The added vodka can really help.

Do I need the stevia extract, or can I make it with only erythritol?
You can do all erythritol.
I wonder if I used canned coconut milk to replace the heavy cream, if it would turn out. I suddenly have to avoid all dairy, but I certainly would enjoy some ice cream again………….
Holy crap Carolyn, I made the custard yesterday and I finished off the ice cream early this morning. I just took some out of the freezer and tried it for the first time and it is the most amazing ice cream I’ve ever had. I don’t have an ice cream churn so I actually just put it into little cups and put it in the freezer and it worked out just fine. Thank you so much for this recipe I’m going to be making it for everyone I know.
So glad you liked it!
Would granulated splenda or stevie work in this recipe instead of erythritol?
It should!
I had lemon/lavender sugar cookies quite a few years ago and the flavor was incredible and one that I remember so well. I HAVE to make this and add the lavender. Thanks for the recipe!
The heat is on here in New Mexico, and I’m looking for cold recipes! I love lemon and this looks wonderful! I make my Hollandaise in a blender with hot, bubbling butter. Then, if it’s too thin, I put it in the microwave for 30 second increments at half power, stirring well with a fork after each time until it’s thickened to my liking. It remains smooth. I wonder if that would work for making this lemon curd? I think I’ll try it, since the ingredients are so similar to my Hollandaise sauce.
Did you do it?
Has anyone ever subbed coconut cream or anything else non dairy for the whipping cream? I would love to try it dairy free.
I haven’t tried that but I should give it a go! It might work.
Carolyn, I believe this just may be the most perfect thing ever!! This is going to be amazingly refreshing in the summer. I cannot wait to try this! We’re still in induction, so it’ll have to wait a while, but by that time, we will be super ready.
thank you!!!
but need the carb count for the lemon curd ice cream please.
How long do you think the lemon curd will keep? I’m making lemon curd cupcakes for a wedding this weekend and if I can make this a couple of days in advance, that is my preference. 160 paleo-esque cupcakes is a pretty huge undertaking. 🙂 Also, THANK YOU! You’re awesome.
The lemon curd will keep for 3 or 4 days, I should think. I had some in a jar for about that length of time. I wouldn’t try to keep it too much longer, with the eggs in it!
This worked beautifully. I doubled the recipe and it worked super well. It actually saved the day!
Glad to hear it!
Lovely post and what an idea: lemon curd into ice cream. I already adore it, not having even tried it yet. Sometimes we just KNOW!. Wonderful photographs. I thought ice cream was very difficult to photograph, but you make it look cool, bright, and lovely. Maybe you'll share some tips when we meet at Camp Blogaway!
Oh, gosh, Carolyn, this ice cream looks incredible! Lemon curd???? It's a must try flavor…now I just need a heat wave 🙂
delicious looking ice cream
Wow, I don't know, but if you can manage it, please let me know. I'd love to hear about it!
Lemon curd is my absolute favorite thing. Ice cream is my second! so this dessert is absolutely perfect for me! I can't wait to try it!
Great post Carolyn! Love the use of lemon curd, too bad I used all of my already 🙁
