Baked Oatmeal

Baked Oatmeal is an easy and hearty dish that’s perfect for warming your soul on those chilly mornings. Make it ahead of time so you’ll have a batch to enjoy all week! With warm seasonings like vanilla, cinnamon, and nutmeg and fresh fruit mixed with a soft center and crispy outside, this is not your grandma’s oatmeal. (No shade to grandma of course!)

No mushy texture here – this dish has more of a bread pudding-like consistency. It’s also completely customizable. You can switch the fruit for whatever is in season or even try a flavored syrup. 

This recipe can also easily be adapted to be gluten free and vegan! One batch also serves about eight, so you can have oatmeal all week or serve it for a big family breakfast or brunch. It makes a great dessert too, you just need to add ice cream!

How to Make Baked Oatmeal

  1. Preheat your oven to 350°F and grease a 9×9 or 11×7-inch baking dish. Set aside.
  2. In a large mixing bowl, combine the oats, milk, eggs, walnuts, syrup, butter, banana, cinnamon, vanilla, baking powder, salt, and nutmeg until combined. Then carefully fold in 1 ½ cups of blueberries.
  3. Pour the batter into the prepared baking dish and top with the remaining blueberries.
  4. Bake the oatmeal for 30-40 minutes until the center is almost set. It should be soft in the middle and not completely dry. If you prefer a drier baked oatmeal, continue baking for a few more minutes.
  5. Serve warm with extra maple syrup, powdered sugar, or fresh fruit as a garnish and enjoy!

Tips and Variations

  • Instead of blueberries, try apples, raisins, walnuts, and shredded carrots for a hearty Fall version!
  • Strawberries, bananas, peaches, raspberries are also great if you want to deviate from the blueberries or want to switch to an in season fruit.
  • This recipe can be easily adapted to be gluten free by using gluten free oats, and even vegan if you switch the dairy products!
  • Substitute the eggs for applesauce or an extra mashed banana to hold everything together.
  • Quick oats can be used but will give you a dryer texture.
  • Frozen fruit works if you don’t have fresh on hand!
