What is baked oatmeal?

We’re all familiar with a warming bowl of oatmeal, but what about baked oatmeal?

Baked oatmeal is oatmeal that’s baked in a casserole dish with other ingredients like eggs, non-dairy milk and mix-ins. It tastes different than a typical bowl of oatmeal and can be cut into squares, almost like an oat-y breakfast cake.

Baked oatmeal is healthy, easy to prepare, stores well in the fridge and is perfect to feed a crowd! It also looks a little fancier than just a plain bowl of oatmeal and can be served on it’s own or with toppings like maple syrup and yogurt.

Ingredients you’ll need

  • Oats: the main ingredient of this recipe! I use large flake gluten-free oats, but you can use quick oats too if that’s what you have on hand.
  • Coconut sugar: to sweeten the Blueberry Baked Oatmeal. You can sub brown sugar here.
  • Cinnamon: to add some flavour!
  • Shredded coconut: this is optional, but adds some extra flavour and texture to the oatmeal.
  • Eggs: To help bring everything together and add some richness to the baked oatmeal.
  • Almond milk: or any type of milk
  • Coconut oil: melted. The fat helps to add flavour to the baked oatmeal
  • Vanilla extract: for flavour
  • Blueberries: I like to use wild ones if I can find them, but any blueberries work!
  • Almonds: sliced almonds are best, but you can leave these out if you like.

How to make this recipe

Mix the dry ingredients together in a bowl, and the wet ingredients together in a separate bowl. When mixing the wet ingredients, beat the egg first to make sure it mixes in well.

  • A bowl of almond milk and eggs mixed together
  • a bowl of oats

Mix the wet ingredients and dry ingredients together until combined. Then add the blueberries and shredded coconut and give it another mix.

  • batter for baked oatmeal in a clear mixing bowl
  • A cup of blueberries being poured into baked oatmeal batter

Add the mixture to a baking dish and bake in the oven for 45 minutes or until golden brown on top.

Recipe variations

Make it vegan: instead of an egg, use a flax egg. Mix 1 tbsp ground flax seeds with 3 tbsp of water and let sit for 5 minutes.

Add any fruits you like: substitute some of the blueberries with any berries, bananas or fruits you love.

Does baked oatmeal have to be refrigerated?

Yes. Baked oatmeal will stay best if it’s stored in the fridge. Store in fridge for up to 4 days, or freeze it for up to 1 month.

If you’d like to prepare this recipe ahead of time, bake it and pop it back in the oven at 350 degrees F for 10 minutes to warm. You can also prepare the batter ahead of time and bake it before serving.

Tips for making this recipe perfectly

  • Use large flake oats for the best texture. You can use quick oats, but large flake oats work best in this recipe. Do not substitute steel-cut oats.
  • The mixture will look a bit liquidy, which is totally OK. As the oatmeal bakes it will absorb the liquid.
  • Serve with a big drizzle of maple syrup, delicious!!
