Baked Oatmeal

Baked oatmeal is one of our family's favorite breakfasts. I try to make a pan every week, especially during the winter months when we are craving something hot that will warm us up. Oatmeal always hits the spot and keeps our bellies full until lunch time.

I love mixing up our baked oatmeal flavors and this Blueberry Maple Baked Oatmeal is perfection. The oatmeal is packed with juicy blueberries, lots of cinnamon, and sweetened with pure maple syrup.

How to Make Baked Oatmeal

Preheat the oven to 350 degrees F. Grease an 8×8-inch baking pan with nonstick cooking spray and set aside.
In a large bowl, mix together the oats, cinnamon, baking powder, and salt. Make sure you use old-fashioned oats and not quick oats.
In a medium bowl, whisk together the milk, pure maple syrup, melted butter, egg, and vanilla. Pour the wet ingredients over the oat mixture and stir until combined. Gently fold in 1 cup of the blueberries. You can use fresh or frozen blueberries, both work great.
Pour the mixture into the prepared pan. Sprinkle the remaining blueberries and chopped nuts on top of the oats, if using. Pecans, almonds, walnuts, and candied pecans are all great options. The nuts give the baked oatmeal a nice crunch and I love the extra kick of protein and healthy fats.
Bake for 40 minutes, until the top is golden and oatmeal is set. Let cool for 5 minutes before serving.
If you need the oatmeal to be gluten-free, you can use gluten-free oats. If you need the recipe to be vegan, you can use a flax egg and melted coconut oil instead of butter.

How to Store

Leftover baked oatmeal will keep in the refrigerator for up to one week. So you can bake it the night before or even several nights before so breakfast is easy on the morning.

To store baked oatmeal, let the oatmeal cool to room temperature and then place in an air tight container and place in the fridge.

And trust me, you will want to have leftovers because having baked oatmeal in the fridge is a breakfast lifesaver on busy mornings. This recipe doubles easily, just use a 9×13-inch pan and double all of the ingredients.

How to Reheat

To reheat baked oatmeal, add your desired amount to a microwave safe bowl and add a little splash of milk. Reheat until heated through, about 45 to 60 seconds. You can top your oatmeal with an extra drizzle of maple syrup if you want a little extra sweetness.
