Secretly Healthy Vegan Baked Oatmeal (No Mixing Bowl!)

You’re going to absolutely love this vegan baked oatmeal recipe. Not only is it secretly healthy (low sugar, gluten free, dairy free, and over 15 grams of plant based protein), but this baked oatmeal recipe is also the easiest baked oatmeal ever.

How? You don’t need a mixing bowl. You’ll just mix everything straight in the casserole dish and bake!

This is the best quick and easy healthy breakfast that tastes like bread pudding in breakfast form!

Ingredients for healthy baked oatmeal

Not only do you not need a mixing bowl for this healthy baked oatmeal, but you also only need a few basic pantry staple ingredients. Nothing fancy here, I promise!

For these vegan baked oats, you’ll need:

  • Old-fashioned rolled oats. The star of this recipe, oats are wonderfully packed with nutrients; in fact, they’re full of both antioxidants and fiber. You can use gluten-free if needed. I wouldn’t recommend steel cut oats here, as they might need a bit longer to cook, and the texture might not be as soft. Additionally, I don’t recommend using quick oats either, as they’ll be too soggy.
  • Pea protein. This is important, as the protein you use will have a big impact on the flavor. I use unflavored pea protein (by Terrasoul), as it has the most neutral taste to me, and you can’t really taste it once baked. However, you can also use Vanilla Pea Protein, such as the one by Nuzest, or Orgain.
  • Dairy free milk. We discuss my favorites down below, but in general, I recommend oat milk or coconut milk, if you don’t mind a coconut milk taste.
  • Maple syrup. I love using Crown Maple- I believe they’re available nationwide, but they’re actually local to where I am! You can also use your favorite local maple syrup, or swap in an equal amount of coconut sugar.
  • Flaxseed “eggs”. These aren’t real eggs, just ground flaxseed mixed with water! You can use unsweetened applesauce too if you’d prefer.
  • Frozen blueberries and/or other fruit. I like to make vegan blueberry baked oatmeal, so I recommend frozen blueberries here. I also top with banana as well! You can use strawberries though, or even frozen raspberries.

As I mentioned above, you won’t need any mixing bowl for these oats. Just a medium casserole dish and a spoon!

What dairy free milk should I use for vegan baked oatmeal?

Much like the vegan protein that you use, the dairy free milk that you incorporate into the oatmeal batter will also affect the taste of your baked oats.

Here are some of my recommendations for dairy free milks:

  • Oat milk: this is the creamiest option without any major taste alterations. I recommend Forager Project, or making your own oat milk.
  • Coconut milk: you can use refrigerated coconut milk or coconut milk from a can. For less sugar, use unsweetened.
  • Nut milk: if you don’t need nut-free, you can use almond milk, or cashew milk!
  • Soy milk: I typically don’t use soy milk, but if you prefer to use soy milk, I recommend a vanilla flavored one.

The easiest way to make vegan baked oatmeal

Once you’ve gathered all of your ingredients, we can begin making the vegan baked oatmeal. Remember that the full recipe is found down below in the recipe card. However, let’s go over the basics.

  • Whisk together the dry ingredients. Just the oats and the protein powder in the casserole dish.
  • Add in the wet ingredients and mix. This includes the dairy free milk, flaxseed mixture, and maple syrup.
  • Top with fruit. I don’t mix in the berries- just leave them on top!
  • Bake! Once baked, you can serve with dairy free yogurt, top with some extra dairy free milk, as I do, or even more fresh fruit!

Blueberry baked oatmeal variations

If you don’t want to make baked oatmeal with blueberries, you can definitely switch it up:

  • Cinnamon baked oatmeal. To make cinnamon baked oatmeal, you can add in 1 tbsp ground cinnamon to the dry ingredients, and top with just banana.
  • Banana chocolate chip baked oatmeal. Add in 1/2 cup dairy free vegan chocolate chips and a banana before baking these oats.
  • Berry Baked Oatmeal. Use your favorite frozen berries as the fruit topping and bake!
  • Mango Coconut Baked Oatmeal. Instead of blueberry and banana, top with frozen mango and 1/2 cup coconut flakes.

Make ahead instructions

If you want to prepare the base of this baked oatmeal before baking it, you can do so the night before.

To prepare this baked oatmeal the night before:

  1. Whisk together the dry ingredients. Just the oats and the pea protein.
  2. Add in the wet ingredients. Mix with a spoon until there are no clumps of dry ingredients left.
  3. Cover with tin foil and place in the fridge. You’ll chill this overnight, much like vegan overnight oats.
  4. In the morning: top with blueberries and banana.
  5. Bake the oatmeal. Preheat the oven, then bake the oats in the oven according to the directions below.
