This Keto Peach Jam is a luscious, sugar-free peach preserve made with fresh peaches and zero refined sugar, perfect for spreading on low-carb toast or stirring into yogurt.

If you have ever stood in front of a jar of peach jam wishing you could just dig in without derailing your low-carb lifestyle, this Keto Peach Jam recipe is about to change everything. It is thick, glossy, intensely peachy, and completely free of refined sugar. Spread it on a cloud bread roll, swirl it into Greek yogurt, or spoon it straight from the jar while no one is watching. We are not judging.
This sugar free peach preserve captures everything you love about summer peaches and none of the sugar crash. It tastes like the real thing because the peaches themselves are doing all the heavy lifting. A touch of lemon, a whisper of vanilla, and the right natural sweetener round it out beautifully.
The right tools and a quality sweetener genuinely make the difference between a jam that gels perfectly and one that stays runny. A heavy-bottomed saucepan prevents scorching, and powdered erythritol or monk fruit sweetener dissolves far more smoothly than granular alternatives.
Traditional jam recipes use enormous amounts of sugar, sometimes pound for pound with the fruit, for two reasons: sweetness and preservation. On a keto or low-carb diet, that much sugar is completely off the table. So this Keto Peach Jam recipe takes a different approach.
Instead of sugar, we use a powdered erythritol or monk fruit sweetener, which gives you the sweetness without the glycemic spike. Instead of pectin (which often requires sugar to activate properly), we use unflavored gelatin, which sets the jam beautifully with no fuss and no carbs.
The result is a no sugar peach preserve that:
Chef's Tip: Use ripe, fragrant peaches for the most naturally sweet jam. If your peaches are a little underripe, let them sit on the counter for a day or two first. The riper the peach, the less sweetener you will need.
Both work wonderfully in this sugar free peach recipe, and the choice really comes down to the season and your pantry.
Fresh peaches are the gold standard from June through August. They bring a floral, sun-ripened quality that is hard to beat. Look for peaches that give slightly when you press them and smell intensely sweet at the stem end.
Frozen peaches are a fantastic year-round option and are often picked and frozen at peak ripeness. Just thaw them completely and drain excess liquid before cooking so you do not end up with a watery jam.
Whichever you choose, this recipe delivers a gorgeous, thick peach butter-style consistency that sets up firm in the refrigerator and stays spreadable straight from the cold jar.
For those of you who love a hands-off approach, this doubles beautifully as an Instant Pot peach butter. Simply add all the ingredients except the gelatin to your Instant Pot, cook on High Pressure for 3 minutes with a 10-minute natural release, then blend and stir in your bloomed gelatin off the heat. It is one of the most effortless sugar free canning recipes style preps you will find, even if this batch is destined for the fridge rather than the pantry shelf.
Important Note: This recipe is formulated for refrigerator and freezer storage only. Because refined sugar is not present to act as a natural preservative, it is not tested or approved for traditional water bath canning. Stick to the fridge for safety and best results.
Once you have a jar of this in your refrigerator, you will find yourself reaching for it constantly. Here are some favorite ways to use it:
The versatility of a good homemade keto peach recipe is genuinely underrated.

This Keto Peach Jam is a luscious, sugar-free peach preserve made with fresh peaches and zero refined sugar, perfect for spreading on low-carb toast or stirring into yogurt.
Bloom the gelatin: In a small bowl, sprinkle the unflavored gelatin powder over the cold water. Let it sit for 5 minutes until it becomes spongy and fully absorbed.
Prep the peaches: Peel, pit, and roughly chop the fresh peaches. For a smoother jam, dice them small. For a chunkier preserve, leave the pieces a bit larger.
Cook the peaches: Add the chopped peaches, powdered sweetener, lemon juice, lemon zest, vanilla extract, and cinnamon (if using) to a medium saucepan over medium heat. Stir to combine.
Simmer and break down: Bring the mixture to a gentle boil, then reduce heat to medium-low. Use a wooden spoon or potato masher to break down the peaches as they cook. Simmer for 20 to 25 minutes, stirring frequently, until the mixture thickens and reduces by about one-third.
Add the gelatin: Remove the pan from heat. Add the bloomed gelatin to the hot peach mixture and stir vigorously for 1 to 2 minutes until fully dissolved and incorporated.
Taste and adjust: Taste the jam and adjust sweetener or lemon juice as needed. The flavor will mellow slightly as it cools.
Cool and jar: Let the jam cool in the pan for 10 minutes, then pour into clean glass jars. Allow to cool completely at room temperature before sealing and refrigerating.
Set overnight: For the best texture, refrigerate the jam for at least 4 hours or overnight before serving. It will thicken further as it chills.
This sugar free peach preserve keeps in a sealed glass jar in the refrigerator for up to 2 weeks. For longer storage, pour cooled jam into small freezer-safe containers and freeze for up to 3 months. Thaw overnight in the fridge and give it a stir before serving.
If you are making this for the week, it doubles and triples easily. Just use a larger saucepan and give it a little extra simmering time to reach that perfect jammy thickness. A batch or two stored in the freezer means you will have a taste of summer peaches long after the season ends.
