Keto jam with contemporary blueberries

It's berry season here in Pennsylvania, which means my keto jam recipe is used fairly!

Of all the jams and jellies I like to make at home, blueberry is a particular favorite.

The flavor profile is unique and I love the deep, rich purple color.

This sugar-free jam recipe is great for spreading on your favorite low-carb bread. It also tastes great in ice cream and yogurt!

At only 1 net carbohydrate per serving, this recipe is also gluten-free and suitable for almost everyone!

Jam vs Jelly

Jam and jelly are similar, but most (including myself) don't know the difference.

Traditional jelly recipes are usually made with pure fruit juice, which creates a beautiful (yet transparent) color. All fruits and fiber are sifted out to achieve a silky smooth consistency.

Jam, on the other hand, uses all of the fruit. It's also lower in sugar and I love seeing the real blueberry pieces everywhere.

Ingredients for sugar-free blueberry jam

Like almost all of my recipes, I try to keep the ingredient list simple.

You need:

  • Blueberries
  • water
  • Lemon juice
  • Sweetener of choice
  • Thickener of choice

Ingredients for Keto Blueberry Jam

Pectin who?

If you look at traditional jam recipes, you will find that many call for the addition of an ingredient called pectin.

Pectin is a type of starch that occurs naturally in fruits and vegetables.

Unfortunately, pectin is a concentrated source of carbohydrates and not a keto-friendly option.

Thicken your jam

My recipe uses a thickener called xanthan gum. It is an extract from seaweed and is great for thickening sauces.

That goes without saying, be careful when adding your xanthan gum! Too much can turn your jam into a thick ball of goose bumps.

Are you looking for another way to thicken your jam? You can also try:

  • gelatin
  • Chia seeds
  • Guar gum
  • Sunflower lecithin

Can i use frozen blueberries?

Frozen blueberries work just fine in a pinch.

The only main difference will be the texture. Frozen fruit tends to get mushy quite quickly, so it may be necessary to adjust cooking times.

Surprisingly, sometimes frozen fruit is even better than fresh. This is because frozen fruit tends to be processed at exactly the perfect time of ripening.

Turn it up with these variations

This recipe makes an excellent base for a variety of other spreads. For example, keto strawberry jam with fresh strawberries is another favorite that I bring out regularly.

You can just as easily swap out the blueberries for:

  • Cranberries
  • Raspberries
  • Blackberries

I also suggest playing with the citrus fruits to create something unique:

  • Add orange or lime juice for a refreshing touch
  • Taste your citrus fruits for a touch of flavor and interesting texture


As usual, you can also swap out the sweeteners for your favorites. I go for allulose in this recipe because it mixes and tastes like sugar with no cooling effect. This brings out the natural sweetness of the blueberries and it's awesome!

Not a huge amount of sweet flavors starting keto? You can reduce the amount of sweetener to 1/4 cup or even remove it entirely!

Even with no added sweetness, this recipe is very forgiving and will still work in the end.

Can I use this jam recipe?

Due to the simplicity of the ingredients, this isn't a recipe that works well for canning.

Acids are used in jams and jellies to preserve the fruit's flavors.

While this recipe uses lemon juice (citric acid), it is not enough to preserve the properties of the jam.

Because of this, I recommended serving in ice cube trays within a week of making or freezing.

Recipes that go well with jam

  • Instead of the raspberries, try turning this blueberry jam into my recipe for raspberry swirl cheesecake.
  • Spread a layer of cream cheese on top of a Zesty Cheddar Biscuit for a salty and sweet flavor combination!
  • Surprisingly, this sauce also goes well with hearty dishes. I like creating my own version of IKEA's Swedish meatball and using my blueberry jam for the cranberry.

Tips for a successful jam

  • If you want your blueberry chunks to be smaller, stop cooking. Use a instead Wooden spoon or potato masher break them. A hand blender works even better.
  • One of my favorite low carb bread recipes is actually a mix! It's Good Dee's all-purpose bread mix.
  • Are you trying to find ways to incorporate jam into your meals? I like adding to my spicy dishes to balance the heat.
  • When you find your jam burn quicklyTry taking off the stove and adding a little more water. Also, start on medium heat – nothing is worse than the smell of burnt fruit!
