I love making overnight oats for breakfast, not only for their convenience but because they just taste so good! When you can make flavors like blueberry cheesecake oats, birthday cake oatmeal, and snickers overnight oats, what’s not to love?

When I need something more filling and satiating on a busy day, I go for these protein overnight oats. They taste incredible, and the extra boost of protein keeps me full for hours!

What are overnight oats?

Overnight oats are a make-ahead breakfast that doesn’t require any cooking. Since rolled oats have been steamed and pressed through a roller to flatten them (hence the name) they can be consumed without cooking.

Instead of cooking, you can simply combine all of the ingredients in a sealable container and store it in the refrigerator for at least a few hours. Soaking the oats softens them enough without requiring any heat. However, you can totally heat them up if cold oats aren’t your jam.

Best protein for overnight oats

When we think of adding protein to our oats, we usually think about protein powder. While there are a lot of awesome plant-based protein powder available, there’s also a lot of whole food sources that are high protein. To get the best of both worlds, we utilize both in this protein overnight oats recipe.

Here are various extra protein sources that would be great to add:

Ingredient notes

This is a great base recipe that you can easily customize with your favorite toppings. For the base you just need 4 simple ingredients:

Ingredients for protein overnight oats measured in bowls and labeled.
  • Rolled oats—Also known as old-fashioned oats, these are the best type of oats for overnight oatmeal! Don’t used steel cut oats as they won’t soften enough and quick oats will get too soggy. Rolled oats are the goldilocks of overnight oats.
  • Unsweetened almond milk—Or any unsweetened non-dairy milk you prefer. For a more creamy consistency you could use oat milk or coconut milk. For some extra protein, soy milk is your best bet since it’s one of the highest protein plant milks available.
  • Protein powder—Vanilla protein powder, chocolate protein powder or your favorite flavor all work great in this! You can even use plain protein powder and add cocoa powder or cinnamon for flavor.
  • Chia seeds—These humble seeds play a huge role in overnight oats. They help to thicken the mixture to take it from soupy to creamy, and they provide additional protein, healthy fats like omega-3’s, fiber and more!

Optional ingredients:

  • Vanilla extract and cinnamon—If you’re not using a flavored protein powder then for extra flavor you can add a dash of cinnamon and a teaspoon of vanilla extract.

The next morning, or whenever you plan to enjoy your protein oats, remove from the refrigerator and add your favorite toppings. I love adding fresh fruit like bananas and berries, shredded coconut, and peanut butter.

Store in an airtight container such as a glass jar.

Serving Suggestions

While you can enjoy these protein overnight oats as-is, here are some fun ways to shake it up:

  • Papaya oatmeal bowls – Serve these oats in papaya bowls! It adds a delicious flavor and there’s virtually no cleanup since you can eat the bowl!
  • Parfait style – Layer your oats with some Greek yogurt or your favorite dairy-free yogurt for some extra protein and creaminess.

Frequently asked questions

Do you have to soak oats overnights?

The name is a bit misleading for being called an overnight oatmeal recipe but you actually don’t have to soak overnight. You really just need 3-4 hours for the oats to soften.

You could technically eat this recipe right away since the oats are already cooked in

How long to protein overnight oats last?

Once prepared, overnight oats can last up to 5 days in the fridge.

Can you heat overnight oats?

I know some people aren’t a fan of cold oats. If that’s you, you can still benefit from the advanced prepping that overnight oats provide, but heat them up when you’re ready to eat.

The easiest option would be the microwave. Leave off toppings and heat in a microwave for 1-2 minutes. Alternatively you can use the stove. Since the oats are already soft from soaking you don’t need to boil them per se, you can just heat through. However, if there’s more liquid than you desire, you can simmer off some of the excess until you reach your desired consistency.

    Just made these last night and was pleasantly surprised how filling they are! I wasn’t hungry all morning when usually I snack. I topped mine with a little peanut butter and strawberries and it tasted like a better PB&J 🙂 Thanks for this easy recipe!
