Let’s take a quick trip to Sicily—picture lemon groves and centuries-old kitchens. That’s where sorbet started. Arab traders mixed Mount Etna’s snow with tart citrus, and Italians turned it into the bright, refreshing dessert we know today.
Here’s the twist: I’ve reimagined it for keto lovers. With monk fruit instead of sugar and the magic of the Ninja Creami, you’ll have a dessert that’s just as satisfying but completely guilt-free. Think of it as sunshine in a bowl—simple, refreshing, and a little taste of history.

Quick Recipe Breakdown
- Prep Time: 5 minutes hands-on
- Total Time: 24 hours (for freezing)
- Servings: 4 (½-cup scoops)
- Difficulty Level: Easy peasy
- Tools Needed: Ninja Creami (or a strong blender)
Make-Ahead Tips:
- Freeze the base up to a week ahead in batches.
- Only have a blender? Pour the mix into ice cube trays and blend the cubes with ¼ cup cold water when you’re ready.

What You’ll Need
- 1 cup warm water (to dissolve the sweetener)
- ¼ cup monk fruit sweetener (or granulated erythritol)
- 1 Tbsp raw agave nectar (optional—skip if you’re strict keto)
- ½ cup fresh lemon juice (3 large lemons should do; bottled works if you’re in a pinch)
Pro Tips for Success
- Want it silkier? Add ¼ tsp xanthan gum to the mix.
- No agave? Try 1 tsp sugar-free vanilla syrup instead.
- Extra flavor punch? Grate in some fresh lemon zest.
How to Make It: Step-by-Step

Step 1: Dissolve Sweetener
Start by whisking warm water and monk fruit sweetener in a bowl until it’s fully dissolved—about 2-3 minutes.
Quick tip: If you see undissolved sweetener, you’ll end up with an icy texture.
Step 2: Add Lemon
Now, stir in your lemon juice and the optional agave. Taste it—does it need a little extra zing? Add a teaspoon of lemon juice at a time until it’s just right.
Fun moment: Your kitchen will smell like a sunny lemon grove!
Step 3: Freeze It
Pour the mix into a Ninja Creami pint. Leave a little space (about ½ inch) below the MAX FILL line, then freeze it flat for 24 hours.
Heads up: Overfilling can lead to messy spills later.
Step 4: Spin to Win
Run the LITE ICE CREAM cycle on your Ninja Creami. If the sorbet looks crumbly, don’t stress. Smooth it out with a spoon and spin again. This part feels a bit like kneading dough!
Goal: A creamy, silky sorbet that holds its shape when scooped.
Fun Variations & Flavor Ideas

Dietary Swaps:
- Going vegan? Use maple syrup instead of agave (though it’s not keto-friendly).
- Paleo-friendly? Replace the monk fruit with 2 Tbsp of raw honey.
Add a Twist:
- Feeling fancy? Add 1 tsp of lavender buds and garnish with lemon zest.
- Spicy kick? Sprinkle on a bit of Tajín chili-lime salt.
- Tropical vibes? Blend ¼ cup of coconut cream into the base.
Seasonal Favorites:
- Winter warmth: Mix in a pinch of minced rosemary.
- Summer fun: Toss in some fresh raspberries before freezing.
Serving & Storing Tips

How to Serve:
- Use chilled coupe glasses for an elegant touch.
- Garnish with a sprig of mint or a thin lemon wheel.
- Want an extra treat? Pair it with keto-friendly almond biscotti.
How to Store:
- Fridge? Nope. It’ll melt unevenly.
- Freezer? Yes, but keep it in an airtight container with parchment pressed onto the surface. Eat within two weeks for the best texture.
- Too icy? Just pulse it in a blender with 1 Tbsp of cold water to refresh it.
Final Thought
This sorbet isn’t just dessert—it’s a little piece of food history. As you enjoy that zesty, refreshing spoonful, imagine it: Sicilian lemon groves, Arab traders blending snow and citrus, and the centuries-long journey to your table. Delicious, right?
