Apple Cinnamon Baked Oatmeal is full of sweet, tender apples, cinnamon, and maple syrup. It’s perfect for feeding the whole family on the weekend or make it ahead and reheat it for a quick and easy breakfast!
Why I love it
Make-ahead breakfast – If you need a quick and hearty breakfast that you can make ahead and reheat throughout the week, this baked oatmeal is for you.
Wholesome healthy breakfast – Oats are a whole grain and a great source of fiber which can help you feel full longer. Oats can also help lower blood sugar levels and your risk of heart disease.
Easy to customize – This baked oatmeal recipe is easy to customize. You can swap apples for another type of fruit, such as pears, or berries. The spices can be swapped as can the toppings for the oatmeal.
Ingredients you’ll need
- Rolled Oats – also called old fashioned oats. They’re thicker than quick oats and have more texture.
- Ground cinnamon and allspice – A warm spice blend often seen in fall baking recipes.
- Baking powder – help the baked oatmeal puff up and rise a bit.
- Milk – Any type of milk works for this recipe. I used unsweetened almond milk.
- Eggs – Eggs help to give the baked oatmeal structure and hold it together.
- Maple syrup
- Vanilla extract or vanilla bean paste – I like to use vanilla bean paste because I find that the vanilla flavor more concentrated.
- Apple – Use a firm, crisp, sweet apple. Honeycrisp, Gala, or Pink Lady apples are all great choices.
- Pecans – optional, but I love pairing apples and pecans together and it’s adds a nice crunchy element to the oatmeal.
How to make apple cinnamon baked oatmeal
Preheat your oven to 350°F. Spray an 8×8 or 9×9 baking dish with cooking spray. If you are using an 8×8 dish the oatmeal will likely need a few more minutes to bake since it will be thicker.
In a large bowl combine the oats, spices, baking powder, pecans, and apples. Stir everything together.
In a separate bowl whisk together the milk, eggs, maple syrup, and vanilla. Pour it in with the oat mixture and stir everything together.
Pour it into the prepared baking dish. If you want to add some visual appeal to oatmeal, add some thin slices of apple to the top. Bake the oatmeal for 35-40 minutes or until it’s set in the middle.
Let the oatmeal cool for at least 10-15 minutes before serving. This gives it a chance to not only cool a little, but firm up. If you try to cut the baked oatmeal immediately after removing it from the oven it will likely fall apart.
Serve the baked oatmeal as is or with any of the suggested toppings listed below.
Toppings for baked oatmeal
There are plenty of options when it comes to how to top your baked oatmeal. Keep it simple and add a pat of salted butter and drizzle of maple syrup or honey.
For a boost of protein, add plain Greek yogurt sweetened with maple syrup and cinnamon and a drizzle of almond butter or other nut butter. This is my favorite way to eat it and what you see in the photos.
Diced apples and pecans or walnuts would be another great topping.
Storage and Reheating
Baked oatmeal can be stored in an airtight container in the refrigerator for 3-4 days. After that I recommend freezing it.
If you want to bake the oatmeal and freeze it for a later date, bake it in a freezer safe dish and one that ideally has a lid. Let the oatmeal cool completely.
Once cool, cover it tightly with a piece of plastic wrap and then put on the lid. If you don’t have a lid, cover the plastic wrap tightly with foil. The oatmeal can be frozen for up to 3 months.
To defrost the frozen baked oatmeal, simply let it sit out on the counter for 45-60 minutes or pull it out the night before and let it defrost in the refrigerator.
To reheat the entire pan of baked oatmeal, cover with a piece of foil and bake in the oven at 350° F. for about 15-20 minutes. You can also reheat individual slices in the microwave.
