Basic Overnight Oats Ratio

The simple ingredients you need to make this recipe include:

  • ⅓ cup fruit 
  • ½ cup oats
  • 1 tsp. chia seeds, optional
  • 1-2 tbsp. sweetener
  • ½ cup milk

Now that you’ve got that basic ratio ready, let’s look into each component of overnight oats.

Old Fashioned Rolled Oats

The most important ingredient in overnight oats is… oatmeal! And the best variety to use is rolled oats.

This type works well because the large flakes soak up the liquid much better than other versions. They also stay delightfully chewy and don’t get mushy or soggy.

However, if you don’t have rolled oats or simply don’t like them, you could use another type. Be aware that instant oatmeal will be quite mushy the next morning, though.

(Are oats gluten-free? Learn all about them!)

Pro tip: If you use steel-cut or instant, you might need to adjust the amount of liquid in the recipe.

Types of Milk

Feel free to use your favorite variety of milk in this recipe.

If you are going dairy-free, unsweetened and full-fat milk is preferable because it enhances the creamy texture of oatmeal and balances out the sweetness of the fruit.

If you choose a plant-based alternative, try one of these:

  • Oat milk – My personal preference since it tastes the closest to regular milk and is super creamy.
  • Almond milk
  • Cashew milk
  • Soy milk
  • Coconut milk

Pro tip: If you are out of milk or prefer not to use it, you can easily sub in water or even fruit juices.


Depending on the types of fruit you use and their ripeness, you may or may not need to add a little extra sweetener. Taste the fruit before it goes into the Mason jar, so you can gauge how sweet you need to make your oatmeal.

I prefer natural options, like maple syrup or honey, but regular sugar or even brown sugar can be used.

Pro tip: You can always add in a little extra sweetener the next morning, so err on the side of less.

Chia Seeds

While chia seeds absolutely aren’t required, they do add SO MUCH!

Not only do chia seeds boost the nutritional value of the oatmeal, but they also give it a deliciously creamy texture.

Pro tip: You can put chia seeds in so many things. Try this Chia Seed Pudding!


The sky is the limit! You can go so many different ways with this ingredient.

Check your local market to see what is in season. Just about every berry is delicious in oatmeal. You can even opt for pears, apples, or bananas.

Or, grab a bag of frozen fruit to make things super simple.

Pro tip: Microwave the fruit for 30 seconds to one minute to get a jam-like consistency. This is essential with more fibrous fruit like pears and apples.

Optional Additions

The best part of this recipe is that you can add so many extra things.

Protein powder adds a powerful punch that will keep you full all morning.

Yogurt is so satisfying and so creamy.

Throw in your favorite spices to really change up the flavor.

If you would rather not use whole fruit, you can opt for a puree instead.

Best Jars for Overnight Oats

Glass Mason jars are far and away the best jars for this purpose. They are super durable, shaped perfectly, and come with a convenient lid.

However, you can use any container with a tight sealing lid.

Pro tip: You can get reusable plastic lids for mason jars that are one piece, so you don’t have to keep track of a lid and a seal. Opt for wide mouth when possible.

How to Make Overnight Oats

These are the steps to follow to make this simple overnight oats recipe:

Add the Fruit

Depending on the consistency you want, you can prepare the fruit in different ways.

For a more solid effect, put the diced fruit to the bottom of an 8-ounce mason jar. Then you’re ready for the rest of the ingredients.

Or, you can microwave the fruit for 30 to 60 seconds. This will create a jam-like consistency in the oatmeal.

Combine all of the Ingredients

Add the rolled oats, chia seeds, milk, and sweetener to the jar with the fruit.

Use a spoon or spatula to carefully stir everything until it is well combined.

Refrigerate Until Morning

Place the lid on the jar tightly. Set it in the fridge.

Let the oatmeal sit for at least 4 hours, or up to overnight.
