Ingredients

Here are a few notes about the main ingredients and substitution options in this recipe:

Rolled Oats – The base ingredient of this baked oatmeal recipe is rolled oats (or old-fashioned oats)!

Cinnamon – A little bit of cinnamon adds a deep, warming flavor to this breakfast recipe. You can also play around with using other spices, like nutmeg and even a tiny bit of clove.

Chia Seeds + Flax Seeds – Optional, but I love adding chia seeds and flax seeds to my baked oatmeal recipes!

Bananas – The bananas are mashed to sweeten and bind the oatmeal. You can also top the oatmeal with a sliced banana! It’s best to use ripe bananas, if possible.

Eggs – Eggs help bind the ingredients together and add protein. However, feel free to use a vegan egg substitute or flax egg recipe instead!

Vanilla Extract – Adds so much flavor!

Maple Syrup – I love how the maple syrup naturally sweetness the baked oatmeal and adds so much flavor. It’s so good! Honey works too, but in my opinion, maple syrup works better.

Almond Milk – Any type of almond milk works great! You can also use other types of milk, such as regular milk, oat milk, soy, cashew, or any other type of non-dairy milk.

Blueberries – Fresh or frozen blueberries are both great options for baked oatmeal bars!

Toppings – Add any toppings to your heart’s desire! I added sliced banana, chopped walnuts, extra blueberries, and sprinkled brown sugar for a delicious touch. You can also add a drizzle of peanut butter!

Make Ahead Baked Oatmeal

One of my favorite things about this recipe is that it can be made ahead for quick and easy breakfasts throughout the week! To make baked oatmeal ahead of time, simply make the recipe according to directions and let cool. Cut into servings and refrigerate in an airtight container. When ready to enjoy in the morning, simply reheat each serving in the microwave for 30 seconds to 1 minute!

Can You Freeze Baked Oatmeal?

Yes! Baked oatmeal actually freezes and reheats wonderfully. To freeze baked oatmeal, simply let the oatmeal cool after baking. Cut into slices and place serving sizes in airtight containers (covered) in the refrigerator for one hour (or more). Move the containers to the freezer and freeze for up to 3 months!

The best way to reheat baked oatmeal is to let it thaw out in the refrigerator the night before you want to enjoy it. Then simply heat it up in the microwave for 30 seconds to 1 minute, or until evenly warm!
