Protein Overnight Oats

Protein Overnight Oats are one of the best easy make ahead breakfasts. Start your day off right with this protein packed recipe!

Overnight Oats

Overnight oats are a classic, but have you ever tried adding protein powder to your oats?

Not only is this recipe delicious, but one (huge!) serving packs around 30 grams of protein!

These can also easily be made vegan, gluten free, and you can prep it in just 5 minutes.

When I was testing this recipe, I made three different versions of overnight oats to see which one was best.

One was a clear winner and that is the recipe that I am so excited to share with you today!

“Whoa. This recipe is UN-REAL. I rely heavily on internet bloggers for recipes and have stumbled across some delightful ones, but I’ve never a comment. This was SO good, I had to come back and drop a note. Thank you for publishing this amazing concoction!! It will be staple in our house going forward. Simple, convenient, nutritious, satisfying, delicious!” -Jessie

Ingredients to make protein overnight oats

Here are the ingredients that you will need to make overnight oats, as well as a few substitutions you can use.

  • Banana – mashed banana is perfect in overnight oats and adds a nice sweetness. I tested two versions of this recipe without banana, and the one with banana was the best tasting.
  • Protein powder – you can use any protein powder you like. I used a vanilla one, but chocolate would work also.
  • Oats – old fashioned oats, also known as rolled oats. You can substitute quick oats if you need to.
  • Unsweetened almond milk – you can use any milk that you have on hand.
  • Peanut butter – you can use any variety you want.
  • Maple syrup – the real stuff. This is the best natural sweetener for oats.
  • Vanilla extract
  • Chia seeds

How to make overnight oats

Step 2: Add the remaining ingredients – protein powder, milk, oats, maple syrup, peanut butter, vanilla extract, and chia seeds.

Notes

This recipe calls for vanilla protein powder, but I have also used chocolate and it is delicious! I have made this recipe with both plant based and whey protein and both tasted great.

Stir it all up to combine.

Step 3: If you have a jar with lid, this is the best way to store overnight oats. Just screw the lid on the jar of oats and refrigerate overnight, or at least 4 hours.

The longer the oats sit, the softer they will be. If you do not have a jar with a lid, just cover the oats with cling wrap.

The oats will thicken up a lot in the fridge, and all the flavors will really combine.

We love making oats for a homemade breakfast that we can prep ahead for busy mornings.

What to put on overnight oats

The topping possibilities are endless! Here are some of our favorite overnight oat toppings.

  • raspberries
  • blueberries
  • blackberries
  • strawberries
  • sliced banana
  • slivered almonds
  • walnuts

Of all of the overnight oat recipes I have tried, this one was by far my favorite! The flavors are rich and they are so filling and satisfying.

My boys love this recipe too, even though I can’t get them to eat regular oatmeal. This would be a great addition to your weekly meal prep!

Storing

Overnight oats will keep in an airtight container in the refrigerator for 3-4 days. Do not add the toppings until you are ready to eat them.
