I can never get enough of strawberries and rhubarb together. Whether it’s in the form of crisp, crumble, pie, cobbler, or galettes, the sweet-tart combo ends up greater than the sum of its parts. The uniquely floral taste of tangy rhubarb melds perfectly with ripe red berries, turning a luscious shade of crimson.

I’ve been capturing these alluring flavors in a quick, small-batch jam gently set with chia seeds to minimize cooking and subtly sweetened with maple syrup. It keeps in the refrigerator for up to a couple of weeks, or in the freezer for up to several months. Sometimes I throw in raspberries if I have some hanging around. I hope you love it!

This low-sugar strawberry rhubarb jam recipe uses just 4 ingredients, and each plays a vital roll.

  • Strawberries and rhubarb are the stars of this show. You can absolutely use frozen fruit if that’s what you’ve got. Feel free to swap some or all of the strawberries for another berry such as raspberries.
  • Chia seed gives the jam a soft set.
  • Maple syrup adds gentle sweetness and extra flavor.

How to Make Strawberry Rhubarb Jam

This jam is quite simple to make. You could probably just throw all the ingredients in a pot, but I like to add them in stages for the best results.

  1. Since rhubarb takes longer to cook than strawberries, start by simmering the rhubarb and maple syrup together until the rhubarb just starts to break down.
  2. Stir in the berries and simmer until the liquid in the pot is reduced by about a third.
  3. Stir in the chia seeds and simmer for 1 minute.
  4. Spoon into jars and chill until set.
  5. Refrigerate for up to 2 weeks, or freeze and enjoy low-sugar strawberry rhubarb jam through the winter months when you’re craving something bright.

Maple-Sweetened: Low-Sugar Strawberry Rhubarb Jam

Most jam recipes are sugary AF, which is part of the reason I avoid making and eating them. Sugar helps set jam; you can also add pectin to help it set with less sugar.

This recipe skips the sugar entirely in favor of maple syrup. This refined sugar-free strawberry rhubarb jam recipe is on the tangy side, so feel free to add more sweetener if you like. Rhubarb’s tartness means that it does want some sweetener to make it palatable.

Chia Seed Jam = Strawberry Rhubarb Jam with no Pectin

Chia seeds have an outer coating with the ability to absorb ten times its weight in water. This quality causes them to form a gel-like consistency when combined with liquid.

Here chia seed replaces pectin as a gelling agent, helping the jam thicken as it sets in the fridge. This further reduces the need for sugar, which, as I said before, is what sets more traditional jams.

Maple-Sweetened Strawberry Rhubarb Chia Jam

Print Recipe  /  Pin Recipe
This tangy low-sugar strawberry rhubarb jam is softly set with chia seed for a light, fresh flavor. Perfect with toast, PBJ, yogurt, oatmeal, & more.
Prep: 15 minutes
Cook: 25 minutes
Total: 40 minutes
Servings: 2 cups


  • 2 cups (230 g / 8 ounces) rhubarb in ½-inch lengths
  • cup (90 ml) maple syrup more to taste
  • 3 cups (13 ounces / 370 g) stemmed, quartered strawberries or halved if small
  • 1 tablespoon chia seed more if you want a firmer set


  • Combine the rhubarb and maple syrup in a medium saucepan. Place over medium heat and bring to a simmer. Reduce the heat to low and simmer gently until the rhubarb is tender and just starting to break down, about 5 minutes, stirring occasionally.
  • Stir in the strawberries and simmer until the jam is reduced by about a third, 10 - 15 minutes. The berries should be very soft and falling apart but not completely disintegrated; I like them to hold a bit of a shape in the finished jam.
  • Stir in the chia seeds and cook 1 minute more. Remove from the heat. Transfer the jam into jars and chill until set, at least a few hours and up to 2 weeks, or freeze for longer storage.


  • You can make this with frozen fruit if you like. Just increase the cooking time if needed. 
  • Feel free to trade some or all of the strawberries for other berries – raspberries, tayberries, blackberries, blueberries, or any others. 
  • See the post above for serving suggestions!
