3-Ingredient Raspberry Chia Jam Recipe

You’ll want to eat this healthy raspberry chia jam with a spoon. This low-sugar, high-fiber spread is almost as satisfying as it is good for you.

I love a generous spoonful of jam on toast, but traditional jams are often packed with sugar. As a dietitian, I prefer spreads that keep flavor high and added sugar low. This easy raspberry chia jam hits the mark: just a few simple ingredients, lots of fiber, minimal added sugar, and a texture that’s perfect on toast, stirred into yogurt, or dolloped over baked oats.

Why you’ll love this chia jam

High fiber: Chia seeds and raspberries provide a boost of dietary fiber that supports digestion and heart health. Each serving delivers a satisfying amount of fiber.

Low sugar: This recipe uses almost no added sugar—just a teaspoon of maple syrup per batch in the version below. You can omit sweetener entirely for a sugar-free option, or add a little more if you prefer it sweeter.

Simple and quick: It takes about five minutes of active cooking and a short rest to thicken. Three ingredients and minimal cleanup make this an everyday recipe.

Versatile: Use it on toast, in yogurt bowls, on pancakes, or straight from a spoon. The bright raspberry flavor pairs well with nut butter, cottage cheese, oats, and smoothies.

Ingredients

Only three basic ingredients are required:

  • 2 cups frozen raspberries (cheaper than fresh and convenient)
  • 4 tsp chia seeds (add more for thicker jam)
  • 1 tsp maple syrup, optional (omit for no added sugar; add more to taste)

How to make raspberry chia jam

Heat a small saucepan over medium heat. Add the frozen raspberries and cover the pan.

Cook the fruit, stirring occasionally, until the raspberries are warmed through and have released their juices, about 5 minutes. The berries should be soft and partly broken down.

Remove the pan from the heat and stir in the chia seeds and maple syrup. Mix well so the chia seeds are evenly distributed.

Let the mixture sit, uncovered, for at least 10 minutes. During this time the chia seeds will absorb liquid and the jam will thicken. If, after resting, the jam is thinner than you like, stir in additional chia seeds a teaspoon at a time. If it seems too thick, add a splash of water and mix.

Tips for success

  • Start with the listed amount of chia seeds and add more only if needed—chia seeds thicken as they sit.
  • Give the jam at least 10 minutes to rest before adjusting texture; it will firm up as it cools.
  • If you prefer a smoother jam, lightly mash the raspberries while cooking or use an immersion blender for a few pulses.

How to serve

This chia jam is excellent as a spread or spoonable topping. Ideas:

  • Peanut butter or almond butter toast
  • Cottage cheese or ricotta on toast
  • Protein yogurt bowls or plain yogurt
  • Baked oatmeal or overnight oats
  • Pancakes and waffles
  • As a swirl in smoothie bowls or porridge

And yes—it’s delicious by the spoonful.

Storage instructions

Transfer the cooled jam to a mason jar or airtight container and refrigerate. Because this recipe contains very little added sugar, it will keep in the fridge for up to three days. For food safety and best flavor, make small batches and refresh every few days rather than storing long-term.

Frequently asked questions

Can I add more maple syrup?

Yes—add maple syrup, honey, or another sweetener to taste. Remember that any added sweetener increases the added sugar content.

Can I use honey instead?

Honey works fine in place of maple syrup. Adjust to taste.

Can I use fresh berries?

Fresh berries work well, though you may need a bit more chia to reach the same thickness. Cook and then rest the jam for at least 10 minutes before deciding whether to add more chia seeds.

Can I use different types of berries?

Absolutely. Blueberries, strawberries, blackberries, or mixed berries all make excellent chia jams. Different berries can alter the texture and natural sweetness; adjust chia and sweetener as needed.
