Perfect creamy lemon gelato, who could say no?
This gelato is made with a pre-cooked custard base that creates a finished product with great texture and mouthfeel. Is it actually gelato? No, but you know it’s not a bad substitute.
You will need an ice cream maker with a gelato setting for this one. You could try to hand churn it, but it will be difficult to recreate the right texture.
This gelato is sugar-free, low carb, and keto. It’s also naturally gluten-free. All kinds of fun in the sun with this recipe. Only 2.9 net carbs per serving too!
Since this dessert is cold with a pop of bright fresh lemon it’s the perfect dessert to finish off a spicy meal or even a summer BBQ!
A soft lemon flavored gelato, perfect for a keto diet
This gelato has a soft lemon flavor. It’s not super tart and it’s not bland by any stretch. It rests somewhere between having a gentle mellow lemon flavor that blends beautifully with the fresh cream.
My husband thought it had a slight floral flavor, and that was pretty accurate. The lemon flavour is there, but is dulled down nicely by the cream and creates wonderfully soft flavor notes.
A little bit about the lemons
Fresh organic lemons here would be best. Since we are using the rind, organic is the way to go.
Bottled lemon juice will not suffice here. It’s too bold, too bitter, too punchy, and creates a lemon flavour that simply pales in comparison to the real thing.
Don’t skip the lemon rind here either. The lemon rind adds all those natural citrus oils to the custard and that’s the bulk of our flavoring.
Make sure you avoid the white pith when grating the lemon rind. We just want that thin outer layer and none of the bitter inside white. The more pith you get with your lemon rind, the more bitterness you add to the finished product.
Lemons are one of my favorite flavors, so I bake with them quite frequently and always have a bowl of them in my kitchen. I have a recipe for a creamy lemon tart that my husband I both love. It’s a heavy rotation recipe, so I always keep fresh lemons on hand just in case the lemon tart craving kicks in (it often does).
A little bit about the custard base
This is a pre-cooked custard base and it is what makes this creamy lemon gelato so good. The custard creates a very smooth finished product that is worthy of a second serving.
You will need to cook this custard base over a double boiler on medium-low heat until it thickens enough to coat the back of a spoon.
Cooking the custard base too fast will scramble the eggs, so low and slow with that heat.
A Note about the Sugar Substitutes

I only ever recommend what ingredient or tools I use for my recipes. You can read more about our disclosure policy here ~
Use your favorite 1:1 sugar substitute.
Powered is preferred over granular, as it blends better and has a nicer texture. Erythritol and xylitol also tend to get grainy when cold, but I found the powdered versions to do it much less especially in ice cream or gelato recipes.
If you don’t have powdered erythritol or xylitol and only have granular, go ahead and give it a blast with a high-speed blender, or food processor. My favorite powdered sweetener by far is So Nourished Monk Fruit Blend, I find it has almost no aftertaste at all.
Swerve and stevia will work perfectly fine here as well as does any powdered erythritol or xylitol.
Just remember, xylitol is poisonous to dogs and cats, so if that’s your choice and you have little furry friends running around, it can be deadly to them.
Serving and Storage Tips
If you put your creamy lemon gelato in the freezer to eat another day, you will need to let it rest at room temperature for at least 15 minutes before digging in. As this gelato has no stabilizers or alcohol it freezes rock solid!
It becomes scoopable after sitting out, but it does take a bit of time to get there.
I like to make my gelato (or even ice cream) a bit in advance and set it in the freezer for 30 minutes to firm up even more. At that state, it’s scoopable and slightly hard.
Directly out of the gelato maker it is still a bit too soft for my liking and that’s why I like to give it an additional 30 minutes in a cold freezer.
This will store in the freezer for up to 4 weeks too, so you can make it in advance.
Looking for More Frozen Low Carb Goodness?
I have a great recipe for a flakey chocolate ice cream that is as much fun to make as it is to eat.
I also have a few frozen desserts on sticks, like these raspberry ripple ice cream bars, and these wonderfully toasted coconut popsicles. Both of them are great low carb options.

Mary says
I made this gelato and it is absolutely scrumptious. Thank you so much for this recipe.
Laura says
Hi Mary, I am so glad you enjoyed it!
Doris leacy says
I have a question on #7 Once the mixture cools add in the last cup of heavy cream and and lemon juice. Whisk until blended.
And and lemon juice. I thought we already put the lemon juice in #1??
Thank you
Laura says
Hi Doris, yes good catch, you add the lemon juice at step one. That was my error, and I made the adjustment in the recipe card. Thank so much for letting me there was an error!
Bobbi says
Hi there, yesterday I tried to make Lemon Gelato with the So Nourished Monk? Erythritol powdered sweetener and it didn’t work, unfortunately. I used the Vanilla Gelato recipe by Laura Vitale and adjusted it. Either I boiled the mix somehow or something went wrong. I have a terrible coil stove top which doesn’t help. My question here is, why do you use almond milk? Is it die to the sugar in milk? I wonder if Fairlife whole would work well? Im worried to waste a whole heap on ingredients again. The gelato was AMAZING all but a slightly eggy aftertaste š I appreciate finding your recipe with the sweetener because I try using this for everything. Not everything works though. I found out sugar helps stabilize, and also helps keep the ice cream and gelato, etc soft. Any thoughts?
Laura says
Hi Bobby, I am not familiar with the recipe you used, but I can tell you that low carb recipes are usually adjusted for various reasons. I’m going to guess that the eggy taste came from too many eggs in the recipe. If your stove is coiled a double boiler would have done the trick to keeping it from cooking too quickly (which will also introduce egginess and weird texture).
Usually, these ice cream and gelato recipes call for 18%-36% cream. I use almond milk to drop the carb count and heavy whipping cream to up the fat to make up for the fat missing in the almond milk. This gives me a much lower carb version at the right fat % for the recipe.
Sugar doesn’t help stabilize the ice cream really. You could actually make ice cream without any sweetener at all. But for softening, yes sugar does help keep the ice cream softer and easier to scoop. In low carb ice cream making, we have a few tricks like adding a few spoonfuls of alcohol. Allulose as a sugar replacement actually does have softening properties in frozen treats, so you could try that. Allulose wasn’t an option for me when I first made this recipe, and that is why it is not mentioned in the post.
Hope that helps!
Marsha says
Laura – can this be made without the ice-cream machine?
Tks
Laura says
Hey Marsha, yes you can make this without an ice cream machine. You will need a large metal container, like a big metal bowl, or a coffee tin. Place the ice cream mixture into the container and place it into the freezer. You will need to pull it out every 30 minutes or so and blend it with a hand mixer. It will take 4-5 blending sessions to get the mixture to an ice cream state (depending on how cold your freezer is set). It won’t be as creamy vs an ice cream maker, but it does do the trick. Hope that helps!
Marky says
Hi Laura,
I cannot find a keto white chocolate lemon ice cream anywhere. When I use your recipe can you recommend the amount of sugarfree chips or vanilla extract… dying to make your recipe! Can’t wait!
Laura says
Hi Marky, if I were making this recipe with white chocolate I would add 1/2 cup of white chocolate, but I would melt the chocolate first, spread it over a cold surface, and scrape it off so that it’s flakey instead of the chips. If you like the solid chips, skip my suggestion. I’d also add two teaspoons of vanilla extract. Hope that helps. Come back and tell us how it was!
