Sugar-Free Strawberry Basil Sorbet is a frozen dessert made from pureed strawberries, fresh basil, and allulose instead of table sugar, churned until smooth and scoopable.
I started making this the summer strawberries got cheap at the farmers market and I had a bag going soft on the counter. Basil was an accident, I had extra from a pesto batch and tossed a handful in the blender. It worked.
The allulose is what makes this sorbet actually sugar-free and still scoopable straight from the freezer. Regular substitutes like erythritol freeze rock hard, allulose behaves close to real sugar in the freezer.
This is a small-batch recipe, about six servings, and it holds in the freezer for two weeks if you keep it covered tight.
Why You’ll Love This Recipe
- No refined sugar, sweetened with allulose instead
- Only 5 ingredients and one blender to clean
- Freezer-friendly for up to 2 weeks
- Bright, herbal twist that isn’t overly sweet
Ingredient Notes
- strawberries: Use ripe, deep red strawberries for the best natural sweetness. Frozen berries work too, thaw them first and skip the added water.
- basil: Fresh basil only, dried loses its brightness fast in a cold puree.
- allulose: Allulose freezes closer to real sugar than other substitutes, keeping the sorbet scoopable. Monk fruit-erythritol blends work but freeze harder, see the FAQ for a fix.
- lemon juice: Balances the sweetness and keeps the strawberry flavor from tasting flat.
- salt: Just a pinch, it sharpens the fruit flavor without tasting salty.
Strawberry Basil Sorbet: No Sugar, All Berry Flavor
Ingredients
Method
- Add the strawberries, basil, allulose, lemon juice, and salt to a blender. Blend on high for 60 to 90 seconds until completely smooth, adding the water a tablespoon at a time if the blades stall.
- Taste the puree and adjust sweetness if needed. Allulose dissolves fully at room temperature but can taste slightly less sweet once cold, so blend in a touch more now if you like it sweeter.
- Pour the puree through a fine-mesh sieve into a bowl, pressing with a spatula to remove the seeds, if you want a smoother finish. This step is optional.
- Cover and chill the puree for at least 2 hours, or until it’s fully cold, below 40 F / 4 C. Warm puree churns into ice crystals instead of a fine sorbet, so don’t skip this.
- Pour the chilled puree into your ice cream maker and churn according to the manufacturer’s instructions, about 20 to 25 minutes, until it looks like soft-serve and holds its shape on a spoon.
- Transfer the churned sorbet to the loaf pan, smoothing the top with a spatula. Press a piece of parchment directly onto the surface to block ice crystals.
- Freeze for at least 4 hours, or until firm enough to scoop.
- Let the sorbet sit at room temperature for 5 minutes before scooping if it’s too hard straight from the freezer. Garnish with small basil leaves and sliced strawberries.
Notes
- Chill puree below 40 F / 4 C before churning for the smoothest texture.
- Press parchment on the surface before freezing to block ice crystals.
- Allulose measures cup for cup like sugar but tastes slightly less sweet cold.
- Ripe, in-season strawberries make the biggest flavor difference here.
Tips for Success
- Use fully ripe strawberries, underripe ones stay tart even after blending with sweetener.
- Chill the puree for at least 2 hours before churning so it freezes fast and smooth.
- Strain the puree through a fine-mesh sieve if you don’t want strawberry seeds in the finished sorbet.
- Add a tablespoon of vodka to the puree if you swap in erythritol, it keeps the sorbet scoopable.
- Freeze the sorbet in a shallow container instead of a deep one, it firms up faster and more evenly.
Variations
- Swap half the strawberries for raspberries for a tarter, deeper-colored sorbet.
- Add a pinch of black pepper or a small splash of balsamic vinegar for a savory edge.
- Blend in 2 tablespoons of coconut cream for a creamier, dairy-free texture.
Storage and Reheating
Sugar-Free Strawberry Basil Sorbet keeps well in the freezer for about 2 weeks in an airtight, freezer-safe container. Press a piece of parchment or plastic wrap directly against the surface before sealing the lid, this slows ice crystals from forming on top.
There’s no reheating step here since it’s a frozen dessert best served cold. If it freezes solid, let it sit at room temperature for 5 to 10 minutes before scooping, or run an ice cream scoop under warm water between scoops.
I don’t recommend making the puree more than a day ahead if you’re not churning right away, fresh basil starts to taste dull and slightly bitter after sitting in the fridge too long.
Serving Suggestions
Strawberry Basil Sorbet works well scooped into chilled bowls with a few fresh basil leaves and sliced strawberries on top for color.
For a grown-up version, spoon it into a glass and top with a splash of prosecco or sparkling wine, it turns into a light float in about two minutes.
I also like serving small scoops between courses at a summer dinner, it resets the palate before the next dish.
FAQ
Why is my strawberry basil sorbet icy instead of smooth?
Icy sorbet usually means the puree wasn’t cold enough before churning, or it sat in the freezer too long without an airtight seal. Chill the puree at least 2 hours below 40 F / 4 C before churning, and press parchment directly on the surface once frozen to block air. Allulose also helps keep the texture soft since it doesn’t freeze as hard as erythritol.
Can I use monk fruit sweetener instead of allulose in this sorbet?
Yes, but expect a harder scoop straight from the freezer since monk fruit blends, usually cut with erythritol, freeze much harder than allulose. Add a tablespoon of vodka or glycerin to the puree to keep it scoopable, and let it sit at room temperature for 10 minutes before serving. The flavor swap itself works fine.
How long does homemade strawberry basil sorbet last in the freezer?
This sorbet keeps for about 2 weeks in an airtight, freezer-safe container before ice crystals start changing the texture. Press parchment or plastic wrap directly on the surface before sealing the lid to slow that down. Let it sit at room temperature for 5 to 10 minutes before scooping if it’s frozen solid.
What goes well with strawberry basil sorbet?
Strawberry basil sorbet pairs well with a splash of prosecco or sparkling wine, a few crushed shortbread cookies, or a drizzle of good olive oil on top for a savory contrast. It also works as a palate cleanser between courses at a summer dinner. Serve it in chilled bowls so it doesn’t melt fast.
Is this strawberry basil sorbet keto and sugar free?
Yes, it’s sugar-free since allulose replaces table sugar and barely affects blood sugar, and each serving has around 9 grams of total carbs with 2 grams of fiber. That makes it a reasonable fit for a low-carb or keto plan, especially compared to traditional sorbet loaded with cane sugar.
Do I need an ice cream maker to make this sorbet?
An ice cream maker gives the smoothest texture, but you can freeze the puree in a shallow pan and scrape it with a fork every 30 to 45 minutes until it’s fluffy and scoopable, about 3 hours total. It will have a slightly coarser, more granita-like texture without the machine.
