We’re bringing you more oatmeal recipes per your request because you’ve been loving all of the others! Previously we’ve brought you overnight oats, other oatmeal bakes and of course our guide on how to make oatmeal! And we get why you love it: oatmeal is a crowd pleaser, so easy to put together and can be so delicious with the right flavor combination! Maple and blueberry together is SO GOOD and we knew it would be delicious as an oatmeal bake, but you can also make these as baked oatmeal cups if you’d like!

This Maple Blueberry Baked Oatmeal is a one-bowl recipe and can easily be made ahead of time, though we do think it is amazing straight from the oven too. This oatmeal bake is based off of our popular Oatmeal Cups recipe so it has the perfect almond milk (or milk of choice) to oats ratio.

So what exactly is baked oatmeal?

If you haven’t had an oatmeal bake before it is essentially an oatmeal casserole! It combines oats, your milk of choice, flavoring and eggs with hands-off baking in the oven! There are a few ways you can serve baked oatmeal, besides digging right in with a spoon! You can scoop out a serving into a bowl and add a little extra milk of choice, like a warm cereal. You can slice it and eat is as, warm or cold. This makes it a great meal prep option as you well; bake it and eat some immediately and pack the rest away for later.

What Oats Should You Use

For this recipe, use rolled oats, not quick cooking oats. If you are gluten-free, make sure the package you buy says gluten-free rolled oats on it! However, make sure not to use instant oatmeal. It’s different than rolled oats or old fashioned oats because it is thinly cut, processed and flavored. They don’t lend the same structure to baked goods as regular oats or quick oats so make sure to check labels.

How do you make baked oatmeal?

Can you freeze baked oatmeal?

Yes! Once it is fully cooled, store in an airtight container for up to 3 months. Either defrost overnight in the refrigerator or give it a quick pass in the toaster oven or microwave to heat up!

Prep Time 00:10 Cook Time 00:40 Total Time 00:50 Yields 9 squares

Ingredients

  • 2 large eggs
  • 1 cup almond milk or milk of choice
  • 1/3 cup maple syrup (see note)
  • 1/4 cup apple sauce
  • 1 tablespoon coconut oil or oil of choice
  • 1/2 teaspoon vanilla extract
  • 1 teaspoon real maple extract (optional)
  • 3 cups gluten-free rolled oats
  • ¾ cup fresh blueberries (see note about frozen)
  • 1 tablespoon chia seeds
  • 1 teaspoon baking powder
  • 1/2 teaspoon fine sea salt

Directions

  1. Pre-heat oven to 350ºF and grease an 8" x 8" oven-safe dish. If desired, prepare a parchment sling by cutting out a piece of parchment paper slightly longer than the pan and placing it inside for easy removal of the baked oatmeal.
  2. In a large bowl add eggsalmond milk, maple syrup, apple sauce, oil, vanilla extract and maple extract (if using) and whisk to fully combine.
  3. To the wet ingredients add oats, blueberries, chia, baking powder, and salt and mix until fully combined.
  4. Pour into prepared dish and bake for 40 minutes, until the center is just barely firm.
  5. Scoop and serve warm as is or with almond milk, or cool and slice into 9 square portions.

Recipe Notes

  1. You can reduce the amount of maple syrup in the recipe to 1/4 of a cup if you prefer a less sweet version. 
  2. Maple extract can be commonly found at most grocery stores. We obviously recommend only buying an all natural extract, and skipping it if it's artificially flavored.
  3. You can use frozen blueberries. Do not let them thaw, or they will streak the whole oatmeal bake purple. You may need an extra minute or two for the total baking time, make sure to follow the instructions about the center being just about cooked through.
