How to Use Chia Seeds: 7 Ways Australians Actually Eat Them

The short answer: the best way to eat chia seeds is soaked. Stir one part chia into three or four parts liquid, wait five minutes, stir again, and give it fifteen minutes to turn into a soft gel. Chia seeds come from the Salvia hispanica plant, soak up around ten times their weight in liquid, and are high in fibre (about 4g a tablespoon). Below are the seven ways most people end up using them: chia pudding, chia water, overnight oats, smoothies, a vegan egg, a seeded sourdough crust, and a sprinkle on yogurt.

Most bags of chia stall at the same point. Someone stirs a spoonful into milk, comes back to a lumpy jar, and the bag goes to the back of the cupboard for a year.

Chia isn't hard to use. It just has one habit you need to know about, and once you've got that, it goes into breakfast most days without any thought. A kilo of our organic chia is $33.17 online, so it's worth getting it out of the cupboard.

What Are Chia Seeds, Exactly?

Chia seeds are the edible seed of Salvia hispanica, a plant in the mint family from central Mexico, where the Aztecs grew it as a staple crop. The seeds are about 1mm long, oval, mottled black and white, and taste of almost nothing.

What they do is the point. Drop them in liquid and they swell into a soft gel, a bit like tapioca. That gel thickens drinks, sets puddings without gelatine, holds vegan baking together and adds chew to bread. Nutritionally they're high in fibre and carry plant omega-3 (ALA) and some protein, though the texture is why most people keep buying them.

Our organic chia seeds are the black kind, which is what you'll see most often. White chia comes from the same plant and behaves the same way.

How Do You Actually Use Chia Seeds?

You hydrate them. Mix chia with at least three times its volume of liquid (water, milk, juice, yogurt) and wait fifteen minutes. The seeds plump up and the liquid thickens. From there you can eat it as is, blend it into a smoothie, bake it into bread, or sprinkle dry seeds over something wet like yogurt or porridge.

You don't need to cook chia. Heat doesn't change much, which is why people searching "how to cook chia seeds" mostly end up stirring them into porridge in the last minute, or baking them into bread and muffins.

One rule matters more than the rest: don't eat dry chia straight from a spoon and wash it down. The seeds swell as they meet water, and there's a published medical case of dry chia expanding in someone's oesophagus. Soak first, or eat them on something moist.

Soaked Chia Seeds: How Long and How Much Liquid

Soaked chia seeds (also called hydrated chia) are just chia that's had time in liquid. Chia seeds in water, milk or juice all work the same way, and the ratio decides what you get:

• 1 part chia to 3 parts liquid: a thick, spoonable chia gel. Good for adding to smoothies, baking or a vegan egg.
• 1 to 4: chia pudding.
• 1 teaspoon to a big glass of water: chia water you can drink.

Fifteen minutes gets you most of the way. Two hours or overnight in the fridge gives a smoother set with no crunchy centres. A jar of chia gel keeps in the fridge for about five days, so it's worth making a cup at a time and spooning it into things during the week.

Seeds clumping together is the most common complaint. It happens because the first seeds to touch the liquid grab it and stick to each other. Stir, wait five minutes, then stir again. That second stir is the whole fix.

1. Chia Pudding (The Default)

This is where most people start, and the ratio works with any milk: four tablespoons of milk to one tablespoon of chia. Stir, wait five minutes, stir again to break up the clumps, then fridge it for at least four hours or overnight.

Coconut milk sets creamiest. Almond milk is thinner and cheaper. Soy works fine. Oat milk sets thicker than the others, so add a little more milk if you like it softer. Sweeten after it has set; sugar stirred in at the start gets lost in the gel.

For toppings, sliced banana, frozen blueberries (they thaw into a syrup), a spoon of peanut butter or some grated dark chocolate all work.

How Do You Make Chia Water?

Stir one to two teaspoons of chia into a glass of cold water, leave it fifteen minutes until the seeds gel, then add lemon juice or a splash of cordial. In Mexico it's called agua de chía or chia fresca, and it's the simplest way to start drinking chia seeds.

A jar with a lid makes it easier: seeds in first, then water, then shake. If it's too thick to drink, add water. Too thin, add another quarter-teaspoon of chia and wait ten minutes.

Some people drink it for fullness. The fibre and gel may help you feel full for longer, though the research is mixed; Healthline's summary is a fair read on what the studies do and don't show.

3. Overnight Oats (Chia Edition)

Rolled oats and chia set together into a soft porridge overnight, no cooking needed.

In a 500ml jar: half a cup of rolled oats, two tablespoons of chia, one cup of milk, a tablespoon of maple syrup or honey, half a teaspoon of vanilla and a pinch of salt. Stir, lid on, fridge overnight, fruit on top in the morning. It makes two breakfasts for one person.

The chia is what stops it being soupy. Much less than a tablespoon and the oats stay wet; much more than three and the chia takes over. Two is about right.

How Do You Add Chia to a Smoothie?

Add a tablespoon of chia to the blender with everything else. A strong blender breaks the seeds up and the smoothie comes out thicker. With a weaker blender, soak the chia in some of the smoothie liquid for ten minutes first so you don't get gritty bits.

Even easier: keep a jar of chia gel in the fridge (see above) and spoon a tablespoon in each morning. Drink the smoothie fairly soon, because chia keeps thickening in the glass.

5. The Vegan Egg

One tablespoon of ground chia plus three tablespoons of water, left for ten minutes, stands in for one egg in most baking. It's the same idea as a flax egg and suits dense, fudgy bakes such as brownies, banana bread and muffins.

Grind the chia first. Whole seeds give a gel with visible specks, which is fine in muffins but odd in a brownie. And it binds rather than lifts, so it won't work in sponge, chiffon or anything that relies on eggs to rise.

Ground Chia Seeds: When to Grind Them

Most of the time you don't need to. Whole chia gels just as well, and you'll still get the fibre. Grinding helps when you want a smooth texture (a vegan egg, a pale cake, a silky smoothie) or when you're mixing chia into flour for baking.

To grind chia, give it about ten seconds in a clean spice or coffee grinder, or a few pulses in a high-speed blender. Grind small amounts, because ground seeds go stale faster than whole ones. Keep any extra in a sealed jar in the fridge and use it within a few weeks.

6. Sourdough Seeded Crust

Add two tablespoons of whole chia in the last fold of a sourdough or any rustic loaf. They bake into the crumb and crust, giving it a darker look and a little crunch without changing the flavour. Brush the outside with water before baking and press on extra seeds if you want a seeded top. Poppy or sesame do the same job.

7. Sprinkle on Yogurt, Porridge, or Toast

The lowest-effort option, and probably the one that gets through the most chia in a year. A teaspoon over Greek yogurt with honey, over porridge, or on avocado toast. Dry seeds are fine here because they soak up moisture from whatever they're sitting on.

Put about 100g in a small jar and keep it on the bench next to the salt. You'll use it far more than if it's in the cupboard.

How Many Grams in a Tablespoon of Chia Seeds?

It depends on the spoon. An Australian tablespoon is 20ml, which holds roughly 16g of chia. Most American recipes use a 15ml tablespoon, which holds about 12g. Either way, a tablespoon gives you around 4 to 5g of fibre.

If a recipe online says "1 tbsp chia" and it's from the US, a level Australian tablespoon is close enough. The ratios in this post use whatever spoon you have, so the proportions stay the same.

How Long Do Chia Seeds Last?

Whole chia keeps well, up to about two years sealed in a cool, dark cupboard, which is longer than most seeds this oily. They hold up better than linseed or hemp, so you don't need to keep them in the fridge. Ground chia doesn't keep as long (see above).

To check a bag, smell it. Faintly nutty or no smell at all is fine. Bitter, sharp or a bit like crayons means the oil has gone off, so throw them out. Store them in glass with a tight lid and a kilo will be finished long before it turns.

What to Do Next

Start with two habits in the same week: the sprinkle (the least effort) and chia pudding (the one that uses the most). The sprinkle gets through about 10g a week and the pudding about 40g, so a month of both uses around 200g without you noticing.

Our organic chia seeds come in 250g, 500g and 1kg. Start with 250g if you're trying chia for the first time, and go to the kilo once pudding is a weekly thing.

Frequently Asked Questions

Can you eat chia seeds raw? Yes. Chia is almost always eaten raw, either soaked in liquid or sprinkled on something moist. The only thing to avoid is eating a spoonful of dry seeds and then drinking water, because they swell as they hydrate.

What happens if you don't soak chia seeds? On yogurt, porridge or a smoothie, nothing much: they soak up moisture where they sit. Eaten dry by the spoonful, they can swell in your throat and are hard to swallow. Some people also find unsoaked chia harder on the stomach.

How much chia seed should I eat per day? A common amount is one to two tablespoons a day, which gives you roughly 5 to 10g of fibre. If you're not used to much fibre, start with one tablespoon and drink plenty of water, because more fibre all at once can cause bloating.

Are black chia seeds different from white chia seeds? Not in any way that matters in the kitchen. They come from the same plant and are nutritionally almost identical. White chia is less visible in pale dishes; that's the main difference.

Can chia seeds replace eggs in baking? In most dense bakes, yes. One tablespoon of ground chia plus three tablespoons of water, left for ten minutes, replaces one egg in brownies, banana bread and muffins. It won't work where eggs make the bake rise, such as sponge cake or souffle.
