Chia Seed Benefits

Now, why eat chia you ask? Well, it’s a little power-packed seed of goodness that I would highly recommend adding to your diet.

The list of health benefits of chia seeds is long and impressive. Chia is a good plant-based source of omega essential fatty acid and it’s high in protein and full of minerals, vitamins and fibre. They’re also high in magnesium, calcium, iron and antioxidants.

Chia seeds are very easy to use, they soak up the liquid and have a nice mild flavour so you can use them in all sorts of recipes from baking to blending.

I love adding them to smoothies, oatmeal, and pancakes. baking and chia seed pudding, check it out:

Okay, on to these chia seed oats I promised. These are so easy and so tasty! Plus, no pots and pans are required.

The base is made from 3 simple ingredients: chia seeds, rolled oats and almond milk and you’ll need less than a minute to prepare them.

With 2 tbsp of chia seeds in this recipe, the texture falls somewhere between chia pudding and oatmeal. The chia seeds really amp up the volume too so you get a nice, big filling serving.

There are two ways you can make these overnight oats:

  1. Mix the chia seeds, oats and almond milk together place in the fridge overnight then add your toppings in the morning.
  2. Mix everything together the night before so it’s ready to grab and go in the morning.

There’s no real advantage to either way, just personal preference. If you have a busy morning, go ahead and add the blueberries and banana the night before, if not, add them in the morning along with any other toppings when you’re ready to eat.

Recipe Notes

These overnight oats are not sweet. I left them unsweetened because you’ll be mixing in banana and blueberries which helps provide a little sweetness.

If you prefer to have them sweetened, I’d suggest adding unprocessed stevia, 1/2 a serving of vanilla protein powder or 1-2 tbsp of pure maple syrup to the chia oat mixture you’ll be leaving overnight.

Alternatively, you can drizzle a little pure maple syrup over top in the morning or add a couple of teaspoons of my sugar-free jam such as my berry chia seed jam.

Topping Ideas

For toppings, I like to add 1 tbsp of melted almond butter and a few chopped almonds. This is optional. Other toppings and mix-ins ideas are unsweetened shredded coconut, fresh raspberries or sliced strawberries, pecans, hemp seeds, cacao nibs or tahini.

This easy chia oats take about 60 seconds to prep and make a great base for any toppings you choose. I went with a classic blueberry and banana combo but other options include your choice of fresh fruit such as peaches, raspberries or strawberries, chopped nuts, chopped dates, cacao nibs, almond butter or coconut.


  • 1/2 cup rolled oats (50 g, use gluten-free certified if needed)
  • 2 tbsp chia seeds (24 g)
  • 1 cup almond milk (250 mL)
  • optional: 1/2 tsp cinnamon and a pinch of sea salt
  • 1/2 a banana, sliced (60 g)
  • 1/2 cup fresh (or thawed frozen) blueberries (75 g)


  1. Put the oats, chia seeds and almond milk (and cinnamon and sea salt if you using) into an air-tight container and store in the refrigerator overnight. Make sure to mix well so there are no clumps.
  2. In the morning, top the overnight oats with the sliced banana and blueberries and add any other optional toppings you desire such as chopped dates, nuts, seeds, cacao nibs, coconut or extra fruit.


  • If you prefer, you can add everything to the container the night before so they’re ready to grab and go in the morning. Both ways are yummy!
  • Optional topping suggestions (choose 1 or 2): 1 tbsp almond butter or tahini, a few chopped almonds or walnuts, 1 tbsp sugar-free jam, cacao nibs, coconut flakes, goji berries, sunflower or pumpkin seeds, fresh raspberries or strawberries.
