Baked Oatmeal Recipe

This delicious Baked Oatmeal Recipe takes just a few minutes to prepare. It’s an easy make ahead breakfast for busy mornings. Top your baked oatmeal with fruit, nuts or nut butter for a hearty and healthy breakfast.

Oatmeal is a favorite for breakfast because it’s nutritious, filling, and easy to customize with your favorite toppings. Recently, rather than cooking oatmeal on the stove, I’ve been making this baked oatmeal recipe.

It is incredibly easy to make! You mix all of the ingredients together in one big bowl, pour it into a baking dish, and bake it in your oven. Then sit down and start your day with a warm, delicious meal.

This basic baked oatmeal recipe is easy to customize. Add your favorite fresh or frozen fruit or nuts to this recipe, or try my Strawberry Banana Baked Oatmeal or Pumpkin Baked Oatmeal. This baked oatmeal is especially delicious with blueberries mixed in.

This recipe makes eight servings, and the leftovers reheat well for a quick breakfast on busy mornings. You’ll find instructions for reheating the oatmeal below.

How to Make Baked Oatmeal

To make this baked oatmeal recipe, you’ll start by combining most of the ingredients in a large bowl: two eggs, milk, water, maple syrup or brown sugar, vanilla, baking powder, cinnamon and salt. Mix these together well using a whisk.

If you prefer a richer, creamier oatmeal, you can replace the water with additional milk.

Next, stir in the oats. If you want to mix in berries, other fruit, or nuts, stir them in now. Pour the mixture into a lightly greased baking dish.

Bake the oatmeal until it is set. A toothpick inserted into the center should come out mostly clean. Serve the oatmeal warm, with toppings as desired.

Make Ahead Directions and Reheating

I’ll often bake this oatmeal the night before and reheat individual servings in the morning for breakfast. Be sure to let the baked oatmeal cool for a while before you put it into the refrigerator.

You can also prepare the baked oatmeal the night before and refrigerate it before baking. I recommend waiting to add any fruit or other mix-ins right before baking. In the morning all that you’ll have to do is put it in the oven and wait for your breakfast to be ready!

This oatmeal recipe tastes just as good reheated. To reheat, scoop an individual portion into a microwave-safe bowl, add a little milk, and microwave until hot. Add toppings as desired and enjoy!

Recipe Variations

• You can add fruit to the oatmeal before baking. Blueberries, raspberries, blackberries, raisins, chopped apple or pears would all be delicious. Or try adding some shredded carrot, coconut or chopped nuts.
• If you have a ripe banana or two, you can mash them and mix the mashed banana in with the wet ingredients. The banana will add natural sweetness!
• You can halve this recipe to make fewer servings. Bake in an 8×8-inch square baking dish.
• To make this recipe dairy-free, use your favorite non dairy milk, such as almond milk.
• To make this recipe gluten-free, use certified gluten-free oats.
• Can you use steel cut oats in this recipe? You can’t swap steel cut oats for the old fashioned oats in this recipe. While you can make baked oatmeal with steel cut oats, it requires a different ratio of oats to liquid and a different baking time.
