Best Overnight Oatmeal Recipes You NEED This Summer

Love oatmeal but hate the Summer heat? These easy overnight oat recipes are perfect for hot Summer mornings!

During busy mornings in the Summer, I love having breakfast already available. And when it’s crazy hot even at 7:00 AM, I don’t necessarily want a hot breakfast!

I discovered overnight oatmeal a few years ago and they have been a game changer. They’re a delicious breakfast you can meal prep and eat from all week!

If this is your first time making overnight oats, or even hearing about them, I’ve got your back! Below I have some amazing and super easy overnight oatmeal recipe ideas, as well as other ingredient ideas that you can add.

What are overnight oats?

Overnight oats can also be called “refrigerator oatmeal”, because you let the oats soak overnight in the fridge. They’re a great way to eat a healthy breakfast that can easily be prepped on a Sunday night.

Instead of cooking oatmeal in a liquid, you soak rolled oats in milk and other favorite ingredients. The next morning, your oatmeal has a creamy texture. And it’s SO good for hot Summer mornings.

You can either eat it cold or heat it in the microwave. But during the Summer, I’m a huge fan of cold oatmeal!

You typically make overnight oats in individual servings. So store them in a Mason jar or other airtight container.

I wrote a more in-depth post on the difference between cooked oats and overnight oats here!

Basic overnight oats recipe

To make overnight oats soft and creamy, I use the following ratios in just about all of my recipes:

  • 1/2 cup rolled oats
  • 1/3 cup milk
  • 1/3 cup Greek yogurt

These 3 ingredients give you a good base recipe- a balance of protein and fiber. And maybe some fat depending on what kind of milk and yogurt you use.

And from there, you can add whatever else you want, like the ingredients below!

Also note that I use only rolled oats. Quick oats might make your breakfast mushy, and steel cut oats need an entirely different ratio of liquid so I don’t even bother.

Best toppings and ingredients

You can eat overnight oats every day for a week and not get bored if you keep changing up the different flavors! Here’s a huge list of favorite toppings you can mix-and-match:

  • Non-dairy milk or milk of choice (Cashew milk, oat milk, almond milk, coconut milk, soy milk)
  • Fresh strawberries or other fresh berries
  • Other fresh fruit like sliced bananas
  • Frozen fruit (You can totally put frozen fruit in overnight oats!)
  • Peanut butter or almond butter
  • Chia seeds or flax seed
  • Protein powder (Orgain is my favorite brand)
  • Chocolate chips
  • Cocoa powder
  • Vanilla extract
  • Brown sugar, honey, or maple syrup
