Protein Overnight Oats (Ten Different Flavor Options!)

Allow me to introduce you to the easiest breakfast in the world: overnight oats.

Rather than oatmeal that requires heating, overnight oats are made by mixing ingredients together in a container and letting them sit in the fridge overnight.

In the morning, you have a delicious breakfast that’s ready to eat right out of the fridge!

It may just be my new favorite breakfast, and I want to show you the way.

Protein Overnight Oats

More specifically, I want to show you ten ways.

No matter what your taste buds prefer, I promise you there is an overnight oats recipe here for you.

 

How to make protein overnight oats

If you’re unfamiliar, overnight oats are as simple as mixing ingredients together and letting them sit in the fridge overnight.

You can even add all the dry ingredients to your containers ahead of time for meal prep and then add the liquid ingredients whenever you’re ready…

Overnight oats dry

The oats absorb the liquid, much like what happens when you make regular oatmeal, so you’re left with a very thick end result.

To make overnight oats high-protein, I use a combination of Greek yogurt and protein powder. The Greek yogurt acts as a great thickening agent that you can’t even taste and the protein powder both thicken the oats and adds great flavor.

You’ll find 10 different flavors of overnight oats here, but they all start with a very similar base of ingredients:

  • Oats (I use quick oats, otherwise known as instant oats, but you can also use rolled oats or old fashioned oats)
  • Greek yogurt
  • PEScience protein powder (it’s a blend of whey & casein protein)
  • Milk
  • Sugar Substitute

Prepped protein overnight oats

Those are the main ingredients I stuck with for each of these, and I spiced them up to make them all completely different.

For every recipe, the directions are exactly the same: mix everything together in a mason jar, bowl, or container, then let it sit in the fridge overnight. That’s it!

Here’s a tip: you can adjust the amount of milk as needed, but I find that 1/2-3/4 cup for each recipe is the sweet spot.

I used PEScience protein powder in each recipe (remember that the code “matt” will save ya money), and I experimented with a bunch of different flavors. But you can use any protein powder you have!

In fact, as you can see in the photo, I used Quest Nutrition Cookies & Cream for one of these batches. Outside of PEScience brand, that specific flavor is one of my go-to’s.

Both PEScience & Quest are a blend of whey protein & casein protein, which leads to a very thick result. Since most people tend to have whey protein, using that will work just fine in this oats recipe.

Before we get into the flavors, you might be wondering where you should start. While I truly loved how each flavor turned out, I’d say that my 3 favorites were Cookie Butter, Strawberry Cheesecake, and Peanut Butter.

Now, let’s dive in…

Customizing your own overnight protein oats

One of the best things about overnight oats is that they are very forgiving. Since there is no heating involved, you can get creative with your ingredients!

If you feel a recipe needs tweaking to satisfy your tastebuds, don’t be afraid to experiment a bit.

 

Here are a few quick ideas for customizing your own overnight oats recipe:

  • Mix your favorite nut butter (like almond butter) into the chocolate overnight oats to make your own peanut butter cup flavor.
  • Add some cereal to your high protein overnight oats to mimic a cereal milk flavor
  • Make your own dairy free plant-based overnight oats by using a vegan protein powder and mixing in fresh berries (a lot of people love adding chia seeds as well)
  • Drizzle some caramel over the top of your overnight oats recipe.
  • The possibilities are truly endless!

Notes

  • I used a flavored protein from PEScience for each of these overnight oats flavors. If you only have basic protein powder flavors like vanilla or chocolate, those will still work fine!
  • PEScience is a blend of whey & casein protein, which I recommend for all my recipes. However, since this requires no heating, it is very forgiving. Most people use whey protein powder, which will work fine here.
  • You can make any overnight oats recipe dairy free. Use a plant based protein, non dairy milk, and non dairy yogurt as your base, then customize your ingredients if needed. Mix everything up in your mason jar just the same and you'll have a great plant-based version.
  • The nutrition facts below reflect the base of each batch (oats, Greek yogurt, protein powder, and milk). If you want specific nutrition facts for each flavor, see the notes above this recipe card.
