For kids (and kids at heart), this sugar free strawberry jello recipe is the ultimate easy treat! Some store bought varieties are loaded with weird stuff, but this keto jello uses real food ingredients — and gets just as wiggly and wobbly as the original.

My kids and their friends went crazy for this fruity low carb jello — they had no idea! They also love sugar free gummy bears (which uses a similar recipe) fruit leather (which also uses just a few natural ingredients), and keto strawberry ice cream (loaded with fruity flavor and nothing fake!).

Why You’ll Love Keto Jello

This jello keto dessert has all the elements you love about regular sweetened gelatin, all in a keto friendly package.

Sugar Free Jello Ingredients

This section will explain how to choose ingredients for the best keto jello dessert, what each one does in the recipe, and substitution options. For measurements, see the recipe card below.

• Unflavored gelatin powder – This sets your jello. I choose a grass-fed variety, but any powdered gelatin will work. (Just make sure it is unflavored.)
• Strawberries – Fresh or frozen should work. Strawberries obviously make sugar free strawberry jello, but you can also use other berries if you like.
• Besti Monk Fruit Allulose Blend – This sweetener dissolves easily and doesn’t crystallize, to ensure a smooth gelatin. Other sweeteners will make the jello gritty.
• Water – Helps the gelatin bloom and also adds extra liquid.

How To Make Sugar Free Jello

This section will show you how to make sugar free jello with step-by-step photos and details about the technique, to help you visualize it. For full instructions, including amounts and temperatures, see the recipe card below.

• Heat berries. In a large saucepan, heat water and berries until boiling, then reduce heat. Stir and mash the berries periodically while water heats and cools.
• Bloom gelatin. Sprinkle gelatin into a bowl with water, whisk immediately, and set aside to bloom.

• Strain. Use a fine mesh sieve to strain the berry mixture, using a spoon to push all the juice into the bowl. Add more water until you reach 3 cups of liquid total.

TIP: For extra clear, smooth jello, use a jelly bag or nut milk bag. This will get every last bit of strawberry pulp out. If you don’t have one, just the fine mesh sieve is still fine.

• Add gelatin and sweetener. Wipe down the pan and add the juice back in. Stir in Besti until dissolved. Add the bloomed gelatin and heat on low, until dissolved.

• Chill. Pour the jello base into a lined dish and chill until set.
• Cut. When fully set, remove jello from the dish using the parchment paper and slice into squares.

• Serve. Pile the jello cubes into serving dishes and enjoy!

Keto Jello FAQs

Is sugar free jello keto friendly?

Most sugarless jellos are dirty keto, but many sugar free jello recipes using store bought powders have artificial colors or sweeteners, like sucralose.

Make your gelatin at home so you know what goes in it. This keto jello recipe uses clean and simple ingredients.

What is sugar free jello sweetened with?

This keto jello is sweetened with Besti, a natural sweetener. Store-bought sugar free brands contain artificial sweeteners, like aspartame.

How many carbs in sugar free jello?

Does sugar free jello have carbs? Store brands do not, but they are also basically entirely artificial. This natural sugar free jello recipe has 6.4g net carbs per serving, which come from the strawberries.

TIP: If you want to cut carbs in half, you can cut the strawberries in half. You’ll need to add more water so that you still have 3 cups of liquid, and may need more sweetener.

How many calories in sugar free jello?

This keto jello recipe has 46 calories per serving.

Is sugar free jello good for you?

When it comes to sugar free jello nutrition, this dessert is rich in protein without the added sugar in conventional desserts. If you make it yourself, it’s an easy way to fit a natural protein boost to your day.

Can I make other sugar free jello flavors?

Yes, you can! You can swap the strawberries for other keto fruit, like raspberries, blueberries, or blackberries. You can also add a little lemon or lime juice if you like those flavors, or use lemon or lime juice in place of the strained strawberry juice. Just make sure you still end up with 3 cups of liquid before adding the bloomed gelatin and sweetener.

Why didn’t my jello set?

Your keto jello could end up runny for several reasons:

• Poorly dissolved gelatin: Make sure you whisk your gelatin completely so it reaches full strength.
• Too much water: Measure your liquid carefully (you need 3 cups total at the end of step 4), otherwise the jello will get too soft.
• Not refrigerated long enough: Gelatin needs time to chill and firm up. Make sure you give it at least 4-6 hours, or ideally let it set overnight.

TIP: If you still have runny jello after following these steps, you may be able to save it: Reheat the gelatin mixture on low heat until liquified and add more bloomed gelatin, then return the mixture to a dish to set.

Can I use a different sweetener?

Different sweeteners will still add sweet flavor, but I highly recommend an allulose based sweetener like Besti because it dissolves the best and will not crystallize when storing. Crystallization will make a gritty jello.

Storage Instructions

Store gelatin in a covered container in the refrigerator for up to 7 days. Since it uses real fruit, how long it lasts will partly depend on how fresh your fruit is.

Can you freeze jello?

Avoid freezing jello. It will damage the proteins and the texture will be ruined.
