In a small bowl, container or mason jar, combine the oats, chia seeds, yogurt, and milk and stir well. Make sure the oats and chia seeds are all evenly incorporated.
Add the lime zest, raspberries and chopped mango. Mix together.
Store in the fridge for minimum 1 hour or up to 1-2 nights. Before eating, add any desired toppings and enjoy!
Notes
Substitutions
Oats
I prefer using large flake oats for overnight oats because they hold the texture better. If you only have quick oats, I recommend reducing the milk by 1-2 tbsp so that it's not too liquidy or mushy.
Greek yogurt
I recommend using Greek yogurt because it's thicker and provides a lot more protein compared to regular yogurt. If you only have regular yogurt, I also recommend reducing the milk by 1-2 tbsp so that it's not too liquidy or mushy.
Milk
If you are looking for a higher protein option, I recommend using dairy milk or soy milk. Other plant-based beverages like almond or oat milk provide much less protein.
Raspberries
Feel free to use fresh or frozen raspberries. If using frozen raspberries, add them to your oats the night before to allow them to freeze overnight. Alternatively, you can microwave them in a small bowl in the morning and then add them when you're ready to eat.
Mango
You can also use fresh or frozen mango. If using frozen mango, refer to the above instructions.
Lime zest
Using lime zest instead of lime juice is a great way to get a punch of flavour, without the added liquid, which could make the dish too mushy. However, if you don't mind the slight change in texture and prefer lime juice, you can add this instead.
