This overnight oats recipe is one of those “set it and forget it” kind of breakfasts that makes mornings a whole lot easier.
You mix it up at night, and by the time you’re getting up and grabbing coffee, breakfast is already done.
It’s creamy, fruity, and just the right amount of sweet.
Plus, it takes barely any effort.
You’ll love the texture from the chia seeds and the pop of juicy berries.
And the best part? It’s totally customizable.
Add more berries, a drizzle of nut butter, or a sprinkle of granola in the morning for some crunch.

- 1 tbsp maple syrup

- Chia seeds help thicken the oats—if you skip them, the texture won’t be as creamy.
- Frozen berries work just as well—no need to thaw.
- Stir everything well before chilling so the chia doesn’t clump.
- For an extra treat, top with a spoonful of almond or peanut butter in the morning.

- Measuring spoons
- Measuring cups

Substitutions and Variations

Make Ahead Tips
You can make a batch for the week! It lasts 4–5 days in the fridge. Just give it a stir before eating. Add toppings the morning you eat it so they stay fresh.
How to Make Overnight Oats with Chia and Berries
Step 1: Add Oats to Jar
Scoop 1 cup of rolled oats into your mason jar or container.
Step 2: Add Chia Seeds
Add 2 tbsp of chia seeds right on top of the oats.
Step 3: Pour in Almond Milk
Pour 1 cup of unsweetened almond milk over the oats and chia seeds.
Step 4: Add Maple Syrup and Vanilla
Drizzle in 1 tbsp maple syrup and ½ tsp vanilla extract.
Step 5: Mix It All Together
Use a spoon to stir everything well so the chia seeds don’t clump.
Step 6: Add the Berries
Add ½ cup of mixed berries (fresh or frozen) on top.
Step 7: Chill Overnight
Seal the jar and place in the fridge for at least 6 hours or overnight.
Leftovers and Storage
Store overnight oats in the fridge for up to 4–5 days. Keep toppings like nut butter or granola separate and add just before eating. You can prep multiple jars at once for the week.
Why This Recipe Works (Quick Science)
Oats absorb liquid overnight, softening up without needing heat. Chia seeds soak up moisture too and create a gel-like texture that thickens the mix naturally. The combo keeps you full longer because of fiber and healthy fats. Plus, the cold soak breaks down starches just enough to make them easier to digest.
Common Mistakes
- Not mixing well: Chia seeds clump if not stirred properly.
- Using instant oats: These get too mushy overnight.
- Adding toppings too early: Things like granola can go soggy if added before chilling.
- Not sealing the jar: It can dry out if left uncovered in the fridge.
What to Serve With
- A cup of hot coffee or tea
- A side of hard-boiled eggs for extra protein
- A fresh fruit smoothie
- Toast with avocado or nut butter
