Blueberry Chia Overnight Oats

A simple breakfast that quietly does a lot of work for your body.
These creamy overnight oats combine oats, chia seeds, and blueberries for fibre, antioxidants, and steady morning energy. Preparing them the night before means breakfast is ready when you are — no rushing required.
The chia seeds gently support digestion, while the oats provide slow-release carbohydrates that help stabilize energy through the morning.

Ingredients Method Notes

Ingredients
  

  • 1/2 cup rolled oats
  • 1 tbsp chia seeds
  • 3/4 cup unsweetened almond milk (or milk of choice)
  • 1/4 cup plain Greek yogurt or coconut yogurt
  • 1/2 cup blueberries (fresh or frozen)
  • 1 tsp maple syrup or honey (optional)
  • 1/2 tsp pure vanilla extract
  • Pinch of cinnamon
Additional toppings (optional)
  • chopped walnuts or almonds
  • unsweetened coconut flakes
  • extra berries

Method
 

  1. In a jar or small bowl, combine the oats, chia seeds, almond milk, yogurt, maple syrup, vanilla, and cinnamon. Stir well so the chia seeds are evenly distributed.
  2. Add the blueberries and gently fold them into the mixture.
  3. Cover and refrigerate overnight, or for at least 4 hours.
  4. In the morning, give the oats a stir. If the mixture is thicker than you prefer, add a splash of milk.
  5. Top with nuts, coconut, or additional berries before serving.

Notes

Why this works in the morning
  • Oats provide soluble fibre that supports steady energy and digestive health.
  • Chia seeds add omega-3 fats and create a gel that is gentle on the gut.
  • Blueberries provide antioxidants that support brain and metabolic health.
  • Protein from yogurt helps keep you satisfied longer.
Gut-Support Upgrade (Optional)
For an extra digestive boost, stir in:
  • 1 tsp ground flaxseed
  • or 1 tbsp plain kefir in the morning
  • or a spoonful of unsweetened applesauce for additional prebiotic fibre
Make-Ahead Tip
Prepare 3–4 jars at once and keep them in the refrigerator for easy breakfasts during the week.
If you prefer warm breakfasts
Transfer the oats to a small saucepan in the morning and gently heat for 2–3 minutes, adding a splash of milk.
