This easy 4-ingredient Raspberry Chia Seed Jam is ready in just 10 minutes and tastes amazing! Made with fresh or frozen raspberries, this healthy homemade jam is naturally thickened with chia seeds — no pectin or added sugar needed. It’s the perfect sugar-free, low-carb, and keto-friendly jam to spread on toast, swirl into yogurt, or spoon over your favorite low-carb desserts.

Breakfast is super important to me – it really sets the tone for my day and keeps me energized.
Most mornings, I’ll go for something savory like veggie omelette with crispy bacon, a bowl of keto granola, or my quick keto breakfast cookies when I’m in a rush.
But every now and then, I crave something sweet – like a peanut butter and raspberry sandwich. That’s when I make this easy sugar-free raspberry chia jam. It comes together in just 10 minutes, is packed with fiber, and adds the perfect naturally sweet, fruity touch to any low-carb or keto breakfast.
Ingredients Needed
To make a fantastic paleo chia jam, you’ll need just a few simple ingredients. I like to call this instant keto jam because it’s ready within minutes and it’s sugar-free—no sugar is used to thicken it or achieve that perfect jam texture.
- 2 cups fresh or frozen berries – I use raspberries because they are very low in carbs and taste great, but you can use any of your favorite berries.
- 2-3 tablespoons chia seeds – These nutrient-packed seeds act as a thickener in this recipe transforming the fruits into jam almost instantly.
- 2-3 tablespoons Erythritol – Use more or less sweetener depending on how sweet you’d like the jam to be.
- 1 tbsp lemon juice

How to Make Chia Jam?
My go-to ratio for berries to chia seeds is two cups of fresh or frozen fruit to 2-3 tablespoons of chia seeds. I usually use 2 tablespoons, but I’ll add a third if I want the jam to be thicker, especially when the fruit is extra juicy.
- Measure 2 cups of raspberries; you can use fresh ones if they’re in season or frozen—either works just as well.
- Place the raspberries in a saucepan over medium-high heat. As they warm up, they’ll start breaking down into a purée-like consistency. Stir constantly for about 3-4 minutes, then remove from the heat.
- Add the chia seeds, sweetener, and lemon juice, stirring well to combine everything. The jam will start to thicken as it cools.
- Allow it to sit for 5-10 minutes before enjoying. Store your sugar-free jam in an airtight container and it will keep for up to one week.

Best Fruits For Chia Jam
- Berries: Raspberries, strawberries, blackberries, and blueberries are all excellent choices for chia jam. They break down easily and have natural pectins that help thicken the jam.
- Cherries: Pitted and chopped, cherries offer a rich, deep flavor and vibrant color.
- Peaches: Fresh or canned peaches can be diced or pureed for a sweeter, softer jam.
- Mango: Chopped mango provides a tropical twist and smooth texture.
- Kiwi: For a more exotic option, peeled and diced kiwi make a bright and tangy jam.
- Apple: Grated or finely chopped apple gives a more textured jam with a milder flavor.
Remember to adjust the amount of sweetener based on the natural sweetness of the fruit you choose.
How to Serve Chia Jam?
- Toast, Bagels, and English Muffins: Spread it over your morning toast, bagels, or English muffins for a sweet start to your day.
- Waffles and Pancakes: Dollop on top of waffles or pancakes instead of syrup for a fruity twist.
- Yogurt Parfaits: Mix with Greek yogurt to create parfaits. Prep these at the start of the week in small mason jars, layering chia jam and yogurt. Add granola just before serving for a crunchy, nutritious breakfast.
- Oatmeal or Porridge: Stir into hot oatmeal or porridge for added flavor and texture.
- Dessert Topping: Use as a topping for desserts like cheesecake, ice cream, or pudding.
- Peanut Butter Sandwiches: Combine with peanut butter for a delicious twist on a classic PB&J sandwich.
- Cheese Pairing: Serve as a condiment on a cheese platter; it pairs wonderfully with both soft and hard cheeses.
- Smoothie Bowls: Swirl into your smoothie bowls for extra flavor and a pop of color.
- Baked Goods: Swirl into muffin or cake batters before baking for fruity pockets in your baked treats.

This looks amazing!! Are the serving size 1 tablespoon? I know it’s an estimate but just curious.
Yes, the macros for this recipe are calculated per tablespoon.
Can this be canned or froze?
I can’t tell for sure as it’s super easy to make, and a batch lasts for 3-4 days in our hour. I never thought of canning this keto chia jam, but maybe someone else tried it and can help you.
This looks wonderful! I do miss preserves so this looks perfect! (I believe steps 2 and 3 are transposed…not sure if step 4 should be there. )
