Baked Blueberry Oatmeal – Cozy baked oatmeal with plenty of blueberries and warm spices. This baked oatmeal recipe is perfect for meal-prep, lazy weekends, and feeding a crowd! 


  • 2 cups rolled oats (certified gluten-free, if needed)
  • 1 1/2 tsp. cinnamon
  • 1 tsp. baking powder
  • 1/4 tsp. salt
  • 2 cups milk (I use unsweetened almond milk)
  • 1/3 cup pure maple syrup
  • 1 egg (or 1 chia or flax egg* for vegan)
  • 2 Tbsp. butter, vegan butter, or coconut oil, melted
  • 1 1/2 tsp. vanilla extract
  • 1 1/2 cups blueberries, divided


  1. Preheat the oven to 375 degrees F. Grease a 2 quart baking dish (like an 8×8 or 9×9″ pan).
  2. In a large bowl, combine oats, cinnamon, baking powder, and salt. Stir to combine.
  3. Pour in milk, syrup, egg or chia egg, melted butter/oil, and vanilla. Stir to combine.
  4. Fold in 1 cup blueberries with a spatula.
  5. Pour oatmeal mixture into your prepared baking dish.
  6. Sprinkle with remaining 1/2 cup blueberries.
  7. Bake at 375 degrees for 35-40 minutes, or until the oatmeal has plumped and the top is golden.
  8. Remove from oven and let stand about 5 minutes before scooping or slicing.


*TO MAKE A FLAX OR CHIA “EGG”: In a small bowl, combine 1 Tbsp. chia seeds or ground flax with 3 Tbsp. water and stir to combine. Let the mixture sit 5 minutes or so to gel and thicken, then add to your recipe as usual.
