🛒 Ingredients

You only need 5 ingredients to make this rhubarb chia jam:

  • 3 cups fresh rhubarb, chopped into ½-inch pieces

  • Âź cup water

  • 2–4 tbsp maple syrup (or honey), to taste

  • 2 tbsp chia seeds

  • 1 tsp vanilla extract or lemon zest (optional, for flavor)

💡 Sweetness note: Taste your rhubarb first. Tart rhubarb will need more sweetener; younger stalks may require less.


👩‍🍳 How to Make Rhubarb Chia Jam

🔥 Step 1: Cook the Rhubarb

Add rhubarb, water, and maple syrup to a small saucepan. Stir and bring to a simmer over medium heat. Cook for 10–12 minutes, stirring occasionally, until rhubarb breaks down and softens.

🥄 Step 2: Mash & Add Chia

Once the rhubarb is tender, mash it slightly with the back of a spoon or a fork. Stir in chia seeds and optional vanilla or lemon zest.

⏲️ Step 3: Let It Thicken

Remove from heat and let sit for 10–15 minutes. The chia seeds will absorb liquid and thicken the jam.

❄️ Step 4: Cool & Store

Transfer to a clean jar or container and let cool completely. The jam will continue to set as it cools.

🌟 Rhubarb Chia Jam Tips

🍓 Add Strawberries or Raspberries

Replace 1 cup of rhubarb with fresh or frozen berries for a sweeter, more balanced jam.

🧁 Adjust Texture

Like it smoother? Use an immersion blender to puree. Prefer chunky? Don’t mash as much.

🍯 Adjust Sweetener

Use maple syrup, honey, date syrup, or agave. For a low-carb version, try stevia or monk fruit—but reduce quantity and adjust for taste.

🍋 Add Citrus

A bit of lemon juice or orange zest adds brightness and balances the rhubarb’s tart edge.


💬 Frequently Asked Questions

❓ Do I need to peel rhubarb?

No, but if your stalks are especially thick or stringy, peeling the outer layer can improve the texture.

🧊 Can I use frozen rhubarb?

Yes! Just thaw and drain it first to avoid excess water. Frozen rhubarb is perfect for this jam.

🥄 Can I use ground chia seeds instead?

Yes, ground chia will thicken the jam just as well and create a smoother texture. Use the same amount (2 tbsp).

⏱ How long does it take to thicken?

About 10–15 minutes after stirring in the chia seeds. If it’s still too thin, add ½ tbsp more chia and wait another 10 minutes.

🍬 Can I make this jam sweeter?

Yes! Add more maple syrup or honey to taste after cooking. Rhubarb is naturally very tart, so customize the sweetness to your liking.

🌿 Is this jam vegan and gluten-free?

Yes! This recipe is naturally vegan (if using maple syrup or agave) and gluten-free.

This Rhubarb Chia Jam is proof that simple, wholesome ingredients can yield stunning results. It’s quick, healthy, and incredibly versatile—perfect for those seeking a seasonal, refined-sugar-free spread that actually tastes like fruit.

Whether you’re spooning it over toast, layering it into parfaits, or eating it by the spoonful (no judgment!), this jam is a fresh way to celebrate spring’s most underappreciated ingredient.
