Author - Alyssa Rimmer

This healthy protein baked oatmeal recipe is gluten-free, vegan and packed with plant-based protein. It's also naturally sweetened and full of fresh fruit!

Protein Baked Oatmeal with Blueberries

What if you could have oatmeal for breakfast but not actually sit in front of the stove stirring it until it's done? I'm here for it. Especially during the summer.

I've got the oatmeal lover's solution: BAKED OATMEAL!

If you've never tried, it's honestly the best. You stir everything together, transfer it to a baking dish and walk away. In about 35 minutes, you'll have a big batch of soft, fluffy oatmeal that will last you all week long. It's kind of like a casserole, but better.

And you can flavor it a million different ways! We're making a batch of protein baked oatmeal and adding in my two favorite fruits: banana and blueberries. It's sweet, it's flavorful and it's the perfect way to start your day!

Ingredients for Protein Baked Oatmeal

Making baked oatmeal is pretty much the same as regular oatmeal, we're just baking it in a pan instead of cooking it on the stove. Nevertheless, you'll need oats! So that's our base.

Then from there, you can really add whatever you'd like. To make my protein baked oatmeal, we're using:

  • vanilla protein powder
  • hemp hearts
  • mashed banana
  • blueberries
  • almonds
  • vanilla

And we'll also use some flax eggs and almond milk to bring it all together.

What Type of Oats for Baked Oatmeal

The best type of oats to use for baked oatmeal is either traditional rolled oats or thick cut rolled oats. You could also use quick cooking oats, but I don't think you'll get the same chewy texture. It might be a little mushier.

Steel cut oats are also doable, but they'll require a longer baking time and perhaps also a longer soaking time.

If you're not an oat fan at all, you can also use quinoa! I recently shared a Triple Berry Quinoa Breakfast Bake recipe that you can absolutely use the same proportions in this recipe.

Basically…you have lots of different options here!

How to make Baked Oatmeal

The first step to making baked oatmeal is to soak your oats. I put them in a large bowl with boiling water and let them sit for about 10 – 15 minutes before adding the rest of the ingredients.

Soaking your oats ahead of time help to soften them a bit, reduces the baking time and also allows the oats to absorb more flavor.

Once you have your soaked oats, you can just stir everything else into that bowl. Then simply transfer that mixture to a baking dish, top it with any extra fruit and bake away. Takes no more than 15 minutes of hands-on time and makes a massive batch of oatmeal to have all week long!

How Long Does Baked Oatmeal Last?

What's great about vegan baked oatmeal is that it lasts for at least 6 days in the fridge. I personally find that vegan recipes last longer since they're not using dairy, eggs or meat.

So since this protein baked oatmeal is dairy- and egg-free, you can enjoy it for at least 5 – 6 days.

The other option is freezing! You can totally freeze your baked oatmeal into individual portions and just reheat it in the microwave or oven when you're ready to serve it. It's honestly one of the best meal prep recipes ever!

An Easy Vegan Meal Prep Breakfast Idea

I know you guys love meal prep-friendly recipes, and as I said, this one is amazing.

One batch of this protein baked oatmeal will serve at least 8 – 10 servings and can be reheated all week long. It's great if you have picky kiddos at home, you have a crazy busy week ahead or you just love oatmeal and don't feel like making it every single morning.

I recommend storing your baked oatmeal in a glass container. I love this set of glass meal prep containers – they stack well, are totally airtight and are great for things like this.

To reheat your oatmeal, simply pop it in the microwave or oven and bring it to temp. You can also eat it cold! I love topping it with some fresh fruit, a drizzle of almond butter and something crunchy on top (like almonds). This is one of my favorite breakfasts and I know you're going to love it too!

  1. Hi ! This oatmeal is a perfect way to start your day. It’s so moist and chewy, perfectly sweet and with an amazing flavor mix. This was very delicious, I just substituted protein powder for whole spelt flour and I also divided the recipe by 2 because I’m alone to eat oats in my family (what a pity !). They really miss something. I mean … it’s so good ! And healthy, right ?
    Thank you for the recipe !

  2. I just made this oatmeal bar recipe. It was really soupy! Its still in the oven and after 50 min is still not done! Was 1 1\2 cups milk correct? This made the batter really wet!

  3. I have baked your recipe for over an hour and it is still soupy in the inside is there something wrong with the combined mixture of the extra milk or is the temperature too long too low

  4. That looks delicious and the recipe is going straight on my “soon to do” list 😍 but do you think I could omet the protein powder? Or can I replace it with something else?

  5. Pretty good! The center was still a bit gooey even after baking an extra 5-10 min so I wasn’t able to cut and freeze/save as bars. I also used a real egg instead of a flax egg. Definitely serve with Almond butter and more bananas to really make it special. Thanks for sharing!
