What is Baked oatmeal?

Baked oatmeal is a warm breakfast casserole that is baked! Oatmeal is a more creamy porridge like consistency that is made fresh on the stovetop or microwave enjoyed hot. On the other hand, this is more of a breakfast casserole, that is cut into squares and enjoyed. A totally different way to eat oatmeal for breakfast.

My favorite part? It can be made ahead, refrigerated and reheated for a quick grab-and-go breakfast for the rest of the week.

Main Ingredients:

For this banana baked oatmeal recipe you will need:

Old fashioned Oats – This recipe works with old fashion oats and not other kinds like steel cut or quick cooking oats. Use gluten free oats for a gluten free option.

Ground cinnamon – Ground cinnamon is the only flavoring used here. Vanilla extract / Ground Nutmeg (for some Fall vibes) can be used if desired.

Banana – Select well ripened bananas and mash them well before using, This is one of the main sweetener for the recipe.

Almond or Peanut butter – Creamy almond butter or peanut butter may be used and Sun butter for a nut free option.

Eggs – Eggs are main binding ingredient. 2 large eggs and it does not matter if they are at room temperature or cold. Use flax eggs for Vegan/Vegetarian option.

Coconut Oil – Melted (not hot) coconut oil or melted butter may be used (again not hot)

Milk – Whole, reduced fat or fat free are all good options. Use dairy-free milk for a dairy free baked oatmeal recipe.

Brown sugar or Maple syrup – Golden or light brown sugar is recommended.

Sliced Almonds – Sliced almonds or chopped walnuts will be great here. More details on toppings are listed below.

Toppings:

Any of these or a combination will make a delicious topping-

  • Sliced almonds
  • Chopped Walnuts
  • Chopped toasted Pecans
  • Shredded Coconut
  • Semi sweet Chocolate Chips (highly recommended)
  • A drizzle of almond or peanut butter after it has cooled
  • Sliced Bananas, strawberries, blueberries, chopped apples are all great options

Best Baked Oatmeal Add-ins:

Few notes to make a best baked oatmeal :

Make ahead instructions: Baked and cooled oatmeal can be refrigerated for up to a week. To reheat – remove one slice from the refrigerator and microwave for about 30 seconds (or longer) to heat up.

9×13 inch pan – The recipe can be doubled to make into a 9×13 inch easy baked oatmeal.

Make it right away – Bake the oatmeal as soon as you make the batter. Do not let it hang out on the counter (or fridge). This will let the oats absorb the liquid.

Can I use steel cut oats?

No. Old fashion oats or rolled oats are the only type of oats that will work in this recipe.

Can I make this dairy free?

Yes, Use almond milk or any other dairy free milk instead of the regular milk.

Cooled baked oatmeal makes cleaner cut squares.

It is not good served cold. Enjoy warm or room temperature.

Cut up oatmeal squares on plates with berries on the side and a bowl of maple syrup to be drizzled.
