These Mango Overnight Oats are the perfect grab-and-go breakfast for busy days. It takes only 5 minutes to prepare before you go to bed and it's ready to eat when you wake up!
What are overnight oats?
Overnight Oats are an easier version of oatmeal. You make them by mixing rolled oats with milk and other ingredients in a jar and leaving them to soak in the fridge overnight. In the morning you can eat it straight from the jar or in a bowl topped with fresh fruit, nut butter, or other toppings.
Rolled oats are naturally gluten-free so this recipe can be both gluten-free and vegan! If you need to, make sure your oats are certified gluten-free to make sure they're not made in a facility that processes wheat.
Ingredients you need
What makes overnight oats so great is that you only need a few ingredients and most are optional, there are a lot of variations and ways to make it your own!
- Oats and milk - I always use rolled-oats because the texture is better than quick-cooking oats. Any vegan milk here works great! I like almond, cashew, or oat milk.
- Mango - I like using fresh Ataulfo Mangoes (also called Honey or Yellow Mangoes) because they're sweeter and creamier but any mango works great here! Fresh or frozen, anything you have on hand.
- Chia Seeds (optional) - I like to add 1-2 tablespoon to my overnight oats but you can leave them out if you're not a fan of the pudding-like texture. I also recommend skipping them if you want to warm up the oats in the morning.
- Sweetener, vanilla extract, more fruit (optional) - Maple syrup, honey, or agave are all great options for sweetener. Use monk fruit drops or stevia to keep the recipe sugar-free. Add vanilla extract if desired or more fruit like strawberries, blueberries, or pineapple.
Tips for the best overnight oats
- Use milk, not water. This will make your oats much creamier and the texture will be so much better. Any plant-based milk works. If you're using canned coconut milk, use 1:1 milk and water.
- Add almond butter or protein powder to make them more filling. You can totally mix your protein powder into your oats for extra fuel!
- Add various fruits. I find overnight oats taste the best when you combine a bunch of different flavors together.
- mango + pineapple + light coconut milk
- mango + blueberries + yogurt + vanilla + cinnamon
- mango + blackberries + lime zest
- mango + peach + raspberry
Overnight Oats FAQ:
Oatmeal is made with oats and milk or water on the stove. Overnight oats are oats and milk mixed in a jar and soaked overnight. Oatmeal is creamier than overnight oats.
Either works, use what you have on hand. I usually use frozen when it's berries and fresh when it's anything I need to chop up. In this recipe, I prefer fresh mango.
1:2 is a great simple ratio to start with. Adjust this to your liking - thicker oats will need less milk and adding chia seeds will require more. I add 3 tablespoon milk for every 1 tablespoon chia seeds. For my overnight oats I mix ½ oats with ¾ cup milk.
Yes, you can eat overnight oats both cold and warmed up. I prefer cold to save time. If I want warm oats, I choose oatmeal instead.
Pro Tip: Avoid warming up oats with chia seeds, they taste the best cold.
I recommend always prepping these the night before. The oats will keep well but the fruit doesn't usually stay fresh for very long. The recipe will taste the best made fresh but if needed, it will keep for 2-3 days in an airtight container in the fridge.

*It's ok to use frozen mango too, I just prefer the taste of fresh mango in overnight oats.
If you’re going to warm up the overnight oats in the morning, I recommend skipping the chia seeds. They turn the oats into more of a pudding and they don't taste as good when warmed up.
