Sweet and icy smooth, this keto strawberry sorbet comes together in a food processor from frozen strawberries, lime juice, and powdered sweetener, at 7.4g net carbs. I pulse the puree until it turns velvet, and I let the freezer firm it up for 30 minutes before scooping. A pinch of salt sharpens the berries.
I started making this sugar free strawberry sorbet a few summers ago when I realized most store-bought sorbets have more sugar than ice cream. Five ingredients, no ice cream maker, and about five minutes of hands-on work. No churning, no custard base, no waiting around.
The base is frozen strawberries, a sugar-free sweetener, and lime juice. I blend everything in my food processor until it’s smooth, then freeze it for about 30 minutes. The trick I’ve learned is to not over-freeze it. Pull it out at that 30-minute mark and the texture is soft and scoopable, almost like Italian ice. Go much longer and it firms up solid (more on how to fix that below).
One thing readers keep telling me about is adding vodka to the mix before freezing. I tried it after seeing Jackie’s comment, and she was right. A teaspoon lowers the freezing point just enough to keep it from turning into a brick overnight. No flavor difference at all. Then my reader Jordan pushed it to a full tablespoon and says he no longer needs the 5-minute counter thaw. I still use a teaspoon, but his version works too. I add it every time I plan to store leftovers. If you skip the vodka, just pull it out 10 minutes before serving and let it soften on the counter.
Strawberries are one of the few fruits I eat regularly on keto. A full cup has about 8.7 grams of net carbs, which is low enough that I can enjoy a generous serving and stay on track. I’ve also swapped in raspberries and blueberries. Both work, but straight strawberry is still my favorite for color. If I mix fruits, I keep strawberries as at least half the total so the flavor stays bright, and my reader Dani swaps the lime for lemon with a little mint before blending. I blind-tested strawberry against raspberry with lime last summer, and the raspberry version was sharper with more depth. The strawberry batch had better color and a cleaner finish, so I keep coming back to it.
I love this dairy free frozen dessert because it fits so many situations. Weeknight treat after dinner, something cool when friends come over, or a palate cleanser between courses if I’m feeling fancy. I’ve spooned it into glasses with a splash of sparkling water for a float that tastes like a berry Italian soda. No one has ever guessed it’s sugar free.
Keto Strawberry Sorbet
This keto strawberry sorbet is my go-to on hot days. The fruity flavor satisfies my cravings for traditional ice cream without any dairy, and I love that it only takes five ingredients. Lime juice, a sugar-free sweetener, frozen strawberries, a little water, and a pinch of salt. I use frozen because they blend into a thicker, creamier base right away (fresh ones work if you freeze them for at least two hours first, otherwise the puree comes out thin and takes much longer to set). The lime juice adds a brightness that rounds out the sweetness, though my reader Ashley found that cutting back on it lets the strawberry flavor come through cleaner. I’ve used lemon juice when I’m out of limes and it works just as well.
Best part? It’s no-churn. I don’t use an ice cream maker. I blend everything in my food processor until it’s smooth, pour it into a freezer-safe container, and I’m done.
What Is Sorbet?
Sorbet is a frozen dessert made from sweetened water and fruit. It’s traditionally churned like ice cream to make it scoopable, but I skip that step entirely with my food processor method. The result is a dairy free frozen dessert that’s light, refreshing, and packed with real fruit flavor.
I find it interesting that sorbet dates back to first-century Rome and Persia. The name comes from the Italian “sorbetto,” and it’s sometimes called Italian ice or water ice because of its roots in Naples. What matters to me is that it’s naturally dairy-free, which makes it a perfect base for a sugar free sorbet. I swap the sugar syrup traditional versions rely on for a sugar-free sweetener, so mine stays a genuinely low carb sorbet I can eat without tracking every gram.
Is Sorbet Keto Friendly?
Traditional sorbet is not keto friendly. Most store-bought versions use regular sugar, and the carb counts are surprisingly high. I checked a few popular brands and some have 30+ grams of sugar per serving. Making my own at home is the only way I can control what goes in. I use a sugar-free sweetener and strawberries (one of the lowest-carb fruits), which keeps this sorbet well within my daily macros.
Sorbet vs. Ice Cream
I get asked about this a lot. The biggest difference is that sorbet is completely dairy-free, while ice cream relies on cream, milk, and often eggs. Ice cream is higher in fat, which is fine on keto, but the sugar content in store-bought versions is usually a dealbreaker for me. Most commercial ice creams pack in carbs from added sugars and mix-ins.
If you want the richness of ice cream without the carbs, my keto vanilla ice cream is one I make regularly. But when I want something lighter and fruitier, this is what I reach for. My dairy free keto ice cream sits somewhere between the two (coconut cream base, no dairy, but richer than sorbet).
Are Strawberries Keto?
Yes, and they’re one of the few fruits I eat regularly. A cup of strawberries has about 12 grams of total carbs and 8.7 grams of net carbs, making them one of the lowest-carb fruits available. I factor them into my daily macros and enjoy them without stress.

Frequently Asked Questions
Why does my sorbet get rock hard in the freezer?
I dealt with this too. Sugar-free frozen desserts freeze harder than regular ones because sugar acts as a natural softener. What I do now is add a teaspoon of vodka to the mix before freezing. It lowers the freezing point just enough to keep things scoopable, and my reader Jordan uses a full tablespoon and skips the counter thaw entirely. I also store mine in a shallow, airtight container because it freezes more evenly and thaws faster. If a batch still freezes solid overnight, I let it sit on the counter for about 10 minutes, then break it into chunks and pulse it in my food processor for 30 seconds. The texture holds up fine, and my batches last about two weeks.
Can I make this in a Ninja Creami?
I've made it both ways. Blend the strawberries, sweetener, and lime juice, pour into the Ninja Creami pint container, and freeze overnight. Run the sorbet program and it comes out incredibly smooth. I still prefer my food processor method because I can eat it in under an hour start to finish, but the Ninja Creami gives a slightly creamier texture if you already have one sitting on your counter.
Which sweetener works best for frozen desserts?
I've tested powdered erythritol, Swerve confectioners, and allulose in this recipe. Allulose is my top pick for anything frozen because it doesn't crystallize the way erythritol can. It keeps the texture softer straight from the freezer. Swerve confectioners is my second choice. My reader Jordan uses it and says it disappears completely into the cold puree with no gritty finish. If I'm using a powdered erythritol blend, I make sure it's finely ground so I don't get that grainy texture in the final scoop.
What if I don't have a food processor?
I've used my Vitamix when my food processor was in the dishwasher. A high-powered blender works, but I need to add a splash more water to get everything moving. A regular blender works too, just blend in smaller batches. The texture comes out slightly less smooth than my food processor, but it's still good. I wouldn't try this with an immersion blender though. Frozen strawberries are too hard for it.
Can I turn this into popsicles or keto sherbet?
I've done both. For popsicles, add a splash more water so the mixture pours easily into molds, then freeze overnight. It works even as written if you spoon it into the molds. For a low carb sherbet, whip about a cup of heavy cream to soft peaks and fold it into the blended base before freezing. The cream makes it richer and more scoopable, almost like soft serve.
Sorbet was the thing I figured I’d just have to live without on keto, so I went in expecting to be let down. It’s the real thing. I ate the second serving standing at the freezer with the container still open. Thanks!
Needed something fast for a birthday party and used frozen strawberries from the freezer. Two guests thought I’d bought it. Melts quick outside, so serve straight from the container.
I sold my ice cream maker two years ago and never looked back, but then basically every keto frozen dessert I found assumed you had one, so I wrote off sorbet entirely. Then I made this and the food processor just… works? It’s smooth, the lime keeps it from tasting like health food, and I’ve made it twice this week. A little mad at myself for waiting this long.
64 calories meant I just made a double batch and called it dinner. Also switched to allulose and it comes out noticeably softer, scoop it straight from the freezer, no waiting.
Jess, allulose is why I stopped using erythritol in frozen desserts anymore. Straight from the freezer is the whole point. Double-batch at 64 calories, hard to argue with.
7.4 net carbs for something this good completely blindsided me. The lime is everything, honestly. Every strawberry sorbet I’ve made without it just tastes like frozen fruit, not actual sorbet.
Skeptical that a food processor sorbet would actually taste good. It’s completely smooth, zero iciness, and the lime hits harder than two tablespoons has any right to. Better than sorbet I’ve actually paid for.
I made this tonight because I had a bag of frozen strawberries sitting in the back of my freezer and honestly didn’t expect much (I am not a confident cook at all), but the food processor made it look so easy I kept double-checking if I was missing a step. When I pulled it out after 30 minutes it had this bright pink color that looked way more put-together than anything I’ve made myself. I almost skipped the lime juice because I thought it was a weird thing to add to a strawberry dessert, but it gives everything this little sharpness that makes you want another spoonful before the first one’s gone. I am currently standing at my kitchen counter eating it straight out of the container and a little shocked this is only 7g net carbs. Double batch next weekend, no question.
My daughter stood at the freezer the whole 30 minutes it was setting, which told me something. Mine came out slightly icier than I expected, so I’ll blend it longer next time, but the lime is what makes it actually taste like sorbet and not just frozen fruit.
Longer blend will help. I’d also try allulose if you used erythritol, it doesn’t crystallize the same way and stays scoopable. And yeah, the lime is the whole thing.
Solid four stars from me. The lime juice does something really nice to the strawberry, but I’d push the freeze time past 30 minutes. Mine needed closer to 45 before it held its shape well enough to scoop.
I’ve been making this with one small addition and the texture is noticeably better for it. A tablespoon of vodka before the freeze (trick I picked up from a gelato method years ago) keeps it soft enough to scoop straight from the freezer without the 5-minute counter sit I used to need. I also switched to Swerve confectioners because it disappears completely into the cold puree, no trace of gritty finish in the final scoop. Made a batch last Sunday after the snow and the lime-strawberry combination tasted sharper than I remembered from summer batches, more tart and bright somehow. Maybe the contrast with the cold air outside makes the acidity read differently. Either way, going back for another batch this weekend.
Tablespoon instead of a teaspoon, hadn’t thought to push it that far. Mine scoops fine at a teaspoon so I never went further. Swerve confectioners in a cold puree is worth noting for anyone who’s had that gritty issue.
Batch four and I finally stopped adding extra lime juice (a habit I brought over from other sorbet recipes). The strawberry flavor comes through so much cleaner without it. Still making this in February because apparently frozen fruit doesn’t know it’s winter.
Four batches in and you figured out the thing I should have said in the recipe. The lime is there for balance but not everyone needs the full two tablespoons. Strawberry-forward is better anyway.
Want to make this the night before a dinner party so I’m not scrambling at the last minute. The recipe says 30 minutes in the freezer, but if it sits overnight does it freeze completely solid or does it stay scoopable?
It’ll freeze solid overnight, yeah. Add a teaspoon of vodka before you freeze it and it stays scoopable. If you skip that, just pull it out 10 minutes before and re-blend for 30 seconds.
I do this now too. One of my readers mentioned the vodka trick a while back and I’ve added it to every batch since. You’re right, no flavor difference but the texture stays way more scoopable even after a few days in the freezer.
Probably a little more liquid so they would pour into the mold better, but this should work even as written if you are able to spoon the mixture into the mold.
