Can you add protein powder to oatmeal?

Adding protein powder to oatmeal is a fantastic way to turn an already bowl of oats into something even more satisfying and delicious.

Typically, one scoop of protein powder adds around 30 grams of protein, and I’ve been regularly doing this each morning. Protein is known for keeping you fuller for longer and helping repair muscles after exercise. 

What we love about this protein oatmeal recipe is just how easy it is to customize. There are tons of protein powder flavors out there, so you can enjoy chocolate oats, vanilla oats, cookie dough oats, and more. 

Make a big batch on the weekends and have breakfast sorted for the week ahead! 

Ingredients needed

This recipe is very simple and uses affordable, everyday ingredients. Here is what you’ll need:

  • Rolled oats. Also known as old-fashioned oats. These have a chewier and more satisfying texture than quick oats. 
  • Water
  • Milk. I used unsweetened almond milk but any milk works. 
  • Salt. Just a pinch to bring out the natural sweetness of the oats. 
  • Protein powder. Either flavored or unflavored. 
  • Mix-ins. Like any good bowl of oatmeal, you can flavor it up any way you like. 

How to make protein oatmeal

Step 1- Cook the oats

Using either the stovetop or the microwave method, combine the oats, water, milk, and salt and bring to a boil. Once boiling, reduce the heat to low and simmer for 2-3 minutes, until the oats are thick.

Step 2- Add protein powder

Moving quickly, whisk in the protein powder, ensuring there are no clumps throughout. If the oatmeal is too thick, stir through some milk or water.

Step 3- Add toppings

Top with fresh fruit, maple syrup, nut butter, chocolate, or whatever toppings you like.

Best protein powder for oats

Not all protein powder is equal. Many of them are loaded with sugar, fillers, and almost as much carbs as protein. Here are the best options to choose from: 

  • Casein protein powder. This protein provides the thickest texture. If you add casein protein, you will need to add an extra 1/2-1 cup of liquid to compensate for it.
  • Brown rice protein powder. Vegan and gluten-free protein powder. It’s thick and mixes well, and can come in a variety of flavors. Be wary though, some brands can have an ‘earthy’ texture, meaning it can have a quite distinct taste. Stick to vanilla, chocolate, or plain varieties. 
  • Whey protein powder. While not as thick as the other two kinds of powder, whey is easy to find at any grocery store and has minimal ingredients.

Storage instructions

  • To store: Leftovers can be stored in the refrigerator, covered, for up to five days. 
  • To freeze: Place the cooked and cooled oats in freezer safe containers and store in the freezer for up to 6 months. 
  • Reheating: Microwave the oats for 30-40 seconds until warm. Add more milk or water, if needed.

Frequently Asked Questions

Is oatmeal a good source of protein?

Compared to other breakfast cereals, oatmeal is a solid source of protein. Each half-cup serving provides 8 grams of protein. 

Other ways to add protein to oats?

If you don’t like protein powder, you can add Greek yogurt, cottage cheese, or a high protein milk and still enjoy at least 12-15 grams of protein. 

What protein can I pair with oats? 

If you enjoy like to enjoy oatmeal with no mix-ins, pair them with some fried eggs or a protein smoothie.

Can I enjoy this cold?

If you’d like cold oatmeal, try protein overnight oats.

    1. Hi Greg- I recommend slowly whisking it in to prevent that happening. It could also be the brand you are using- would you mind letting me know which one and I can look into it for you?

  1. I make overnight oatmeal in my slow cooker. I put a glass container with my oatmeal mixture into a water bath and cook it overnight. Would you suggest adding the protein powder at the beginning or after it is cooked. Does cooking affect the protein powder?

  2. This one sounds good.
    My personal favourite is one I made up and call “apple crumble oats”. I use rolled/porridge oats and add to them (sweet) ground cinnamon, sweetener (to taste), soy milk, Skyr vanilla protein yogurt and a diced apple (Gala apples are my favorite as they are lovely and sweet – you can remove or leave the skin on the apple according to preference). It is gorgeous, I make enough for a week of breakfasts/puddings and the only problem is trying not to eat the lot! 😂

  3. HA! we would be a pair if we were in NYC together… my favorite place too, but if we were both stressed at the same time? nope, it would not be pretty. I whip my hair and freak out too.

    chocolate oatmeal might help.

  4. I usually cook oats with water, often add shredded carrot, sometimes shredded zucchini, cinnamon, sometimes cocoa powder and cook until thickened. Usually I put all ingredients in there just right at the beginning and cook until done (except eggs, I stir that in last). I eat it hot! I only eat uncooked overnight oats cold.
    I don’t think anyone does not like peanut butter, like everyone is claiming to be the biggest pb addict in the world!

    1. and I just realised that this is a very old post 😀 I thought it’s a new one that I have missed, lol. Your welcome for my oatmeal cooking directions! hahahaha

  5. Bahaha, Oprah looks sooo scary yet very cute. I might invite her to Zurich and show here where to find affordable handbags (haha….)
    I LOVE the spotlight on you Mr. Twerk!!
    I am with you on the eggs. I freak out when there’s only one pack left, seriously, I eat so MANY!
    I love them as an omelette, but even better combine them with oats – and cook eggy oats. Store them overnight and warm up in the morning – EGGY OAT BAKE here you are and I love you. Throw in a few pieces of kabocha and I am doing a happy dance (not that anyone wants to see that :-))

    1. LOLLLLLLLLLLLLL. I nearly fell of my chair. and speaking of chairs. as Oprah would say- LOOK UNDER YOUR CHAAAAAAAAAAAAIRRRR. A NEWWWWW CARRR.

      I can’t wait to meet you, Lucie. All we need are eggs, kabocha and we’d be set!
