What Is Protein Baked Oatmeal?

Protein baked oatmeal mainly consists of oats, a high protein source and various flavorings.

You can keep this recipe basic by using minimal ingredients, but this recipe has a list to make this fully packed with protein and with flavor. If you have these ingredients stored at home, give them a try.

Whether you plan to make protein-baked oatmeal for one or for your family, this recipe can make up to 12 slices that you can meal prep for the week.

Why you will love this recipe?

  • Pre-workout snack: This recipe has slow-releasing carbohydrates and whey protein powder which means this can be a great snack for a pre-workout or an instant fuel for a post-workout which is great for runners and bodybuilders.
  • Macro-friendly: It is a very macro-friendly meal or snack, and you can use it to your advantage depending on your goal and how you exercise, but each serving can realistically fit in any diet plan.
  • Quick breakfast idea: If you are busy in the mornings and do not have much time to make anything fresh before you head off to work, this baked oatmeal only takes 40 seconds to reheat in the microwave and will keep you feeling full.

Recipe Ingredients

Rolled Oats – Use either rolled oats or steel-cut oats for the baked oatmeal. The latter is more renowned for this type of recipe, but rolled oats are perfectly fine for any protein oatmeal bake.

Vanilla Protein Powder – If you want to turn this into a protein-packed baked oatmeal, I would suggest using vanilla flavored protein powder, in either a whey or casein type, as this will ensure that two servings of this oatmeal will have 20 grams of protein and keep the taste neutral. It is totally fine to not use protein powder, if you want to make a standard baked oatmeal. In terms of the flavor, and whether you can taste the protein power, I do not notice much difference when I use vanilla protein powder. There are recipes where you can use chocolate flavoring, but you would need to adjust the other ingredients accordingly.

Coconut Milk – This milk is perfect for this recipe, but you can also use regular milk or your preferred plant-based variation.

Plain Coconut Yogurt or Greek Yogurt – I would usually just use Greek yogurt, which is another rich protein source, but for this recipe I used coconut yogurt which helps with the flavor.

Eggs – I use the whole eggs for this recipe. If you are on a plant-based diet, you can use flax eggs as an alternative.

Maple Syrup – This recipe definitely requires a sweetener – once I forgot, and it was difficult to eat! So I would suggest using your preferred sweetener. Maple syrup is amazing for this recipe, but honey is also great.

Cinnamon – You will also need spice to go with the sweetener, and therefore cinnamon powder is perfect. If you like the taste of cinnamon, you can add an extra teaspoon.

Banana – Banana always goes great with oats, and you can add the toppings halfway through cooking. There are other fruit options too which you can top the baked oatmeal with such as blueberries.

Peanut Butter – Use your favorite nut butter to finish off the toppings. Peanut butter or almond butter are usually perfect.

Others – I used coconut oil, vanilla extract and baking powder for this recipe.

Recipe Tips

  • To make vegan-friendly protein oatmeal: Use flax eggs instead of regular eggs and use a plant-based vanilla protein powder. Also, using coconut yogurt, milk and oil help keeps the flavor consistent.
  • To keep it nut-free: Do not use any nut butters, this is just optional to help with the toppings.
  • If you do not have protein powder: I only use protein powder as a way to get more protein into this recipe and help meet my daily intake goal. If you do not have protein power, you can still follow the same instructions, and just make a standard oatmeal bake which is still healthy and great.

Can You Reheat Protein Baked Oatmeal?
