Overnight oats are one of the easiest make-ahead breakfasts you can make.

The night before, you simply stir together rolled oats, sweetener, and a base such as almond milk. The next morning, you have a creamy and slightly chewy oatmeal.

The best part about overnight oats is how customizable they are. In this version I add blueberries, lemon zest, and protein powder but you can get creative and make it however you like.

Why You Need This Recipe

  • It’s high in protein and soluble fiber which makes it a very filling breakfast. Unsweetened protein powder and chia seeds add protein while the oats are naturally full of fiber and important vitamins.
  • Rolled oats are affordable which makes overnight oats a budget-friendly breakfast choice.
  • Since you meal prep them the night before, there is virtually no cleanup in the morning.

Key Ingredients

Rolled oats make the base for overnight oats. Make sure to buy old fashioned or rolled oats and not quick cooking or steel cut oats. If you are gluten intolerant or Celiac, make sure to buy certified gluten-free oats.

Unsweetened almond milk make these oats thick and creamy without the need for dairy. You could also substitute oat milk, cashew milk, or regular milk if you can eat dairy. You can also add a scoop of Greek yogurt if you aren’t on a dairy-free diet to add even more protein.

Chia seeds absorb whatever liquid they’re added to and make it creamy plus they’re full of protein and healthy micronutrients.

Unsweetened protein powder adds a good dose of protein without the addition of refined sugars. Look for one that is free of additives and made with clean ingredients (see my list of the best paleo protein powders). If you aren’t on a dairy-free diet, you can use a whey protein powder. Vegans should use a vegan protein powder.

Maple syrup or honey adds a natural sweetness to the oats. You can adjust the amount based on how sweet you like your oats.

Vanilla gives this recipe that something extra with that slight vanilla flavor.

Lemon pairs so well with blueberries and gives these oats a fresh lemony taste.

Recipe Steps

Step One

In a bowl or a Mason jar, combine the rolled oats, chia seeds, protein powder, sweetener of choice, vanilla, blueberries, lemon, and almond milk.

As always, please do see the recipe card at the end of this post for the exact ingredients and measurements.

Step Three

Cover the bowl and put the oatmeal mixture in the refrigerator for at least 2 hours or up to 24 hours. The longer it sits the thicker and creamier it will become.

Step Four

When you’re ready to serve stir the mixture and serve cold or room temperature. Add any toppings including peanut butter, almond butter, fresh berries, or anything that you wish, and enjoy!

Recipe Tips & Substitutions

  • If you aren’t on a dairy-free diet, you can use regular milk.
  • You can substitute other types of fruit for the blueberries, if you prefer. Strawberries and bananas work great too.
  • If you don’t have chia seeds, you can leave them out.  
  • If you would like your overnight oats to be sweeter, gradually add more maple syrup or honey until you reach the desired sweetness.
  • The amount of liquid you need is somewhat of a preference. If you don’t want your oatmeal quite as thick you can add a little bit more milk. If you want it thicker you can add a bit less. Although I do recommend following the recipe exactly the first time around.

FAQs

Are overnight oats gluten-free?

Yes just be sure to purchase rolled oats that are certified gluten-free. Regular oats are grown and processed around gluten-containing grains which makes cross contamination highly likely.

Can you eat overnight oats hot?

Although one of the defining qualities of overnight oats is their cold and slightly chewy texture, they can be served hot as well. Simply microwave or cook them on the stovetop until the mixture is warmed through.

How many grams of protein does overnight oats have?

This recipe includes about 24 grams of protein per serving.

Can I use steel cut oats in this recipe?

No because they will not get soft enough to chew. It’s best to use rolled oats for overnight oats.
