Baked Oatmeal Ingredients:

This healthy Baked Oatmeal recipe is packed with good-for-you ingredients you probably already have on hand!

  • Banana: the riper the better! You can also sub the banana for applesauce or Greek yogurt.
  • Milk: I use low-fat milk but any kind will work. You can even use plant-based milk!
  • Eggs: give the oatmeal a protein boost for a more filling breakfast and help bind the casserole together.
  • Maple Syrup: you can substitute the maple syrup for any sugar or sweetener, like honey or brown sugar.
  • Vanilla Extract: gives the oatmeal flavor depth and warmth.
  • Baking Powder: keeps the oatmeal light and fluffy!
  • Cinnamon and Salt: cinnamon adds sweet spiciness while salt helps enhance flavor.
  • Rolled Oats: use large flake rolled outs for the best texture. For a finer texture, you can also use quick or instant oats.
  • Mix-Ins/Toppings: you can use any mix-ins you like! Try blueberries, raspberries, chopped strawberries, chocolate chips, or nuts!

Baked Oatmeal FAQs

Is Baked Oatmeal healthy?

Totally! Baked Oatmeal is packed with healthy carbs from the oats, protein from the eggs, and fruit and nuts which are loaded with nutrients. Baked oatmeal makes a delicious, filling, and healthy breakfast!

Can you use steel cut oats?

Steel cut oats are harder and take much longer to cook than rolled oats. Using steel cut oats will not work in this recipe!

How to store:

Baked oatmeal will last in an airtight container in the fridge for 3-4 days.
You can also freeze it!

Can this be frozen?

Totally! Baked oatmeal is the best make-ahead, freezer-friendly meal prep option. To freeze it, bake as directed, cool completely, then store in an airtight container in the freezer for up to 3 months.

How to reheat:

To reheat baked oatmeal from the fridge, microwave or warm in the microwave until heated through. To reheat baked oatmeal from frozen, bake at 350ºF in the oven or wrap individual slices in a paper towel and warm in the microwave until heated through.

  • Dairy-Free: Swap the regular milk for any variety of non-dairy milk.
  • Vegan: Use non-dairy milk and flax egg in place of regular egg. For this recipe, mix together 2 tablespoons of flax meal and 6 tablespoons of water. Let that mixture sit for 15 minutes in the fridge before incorporating it into the oatmeal.
  • Gluten-Free: Simply swap the rolled oats for gluten-free rolled oats! Also verify that all of the ingredients you use are certified gluten-free.
  • Use frozen fruit. If you’re mixing fruit into the oatmeal, you can use frozen fruit in place of fresh fruit. However, this will require a longer cooking time—probably closer to 45 minutes. It’s a good idea to let frozen fruit thaw before adding to shorten the cook time.
  • Boost the nutrition. Pack this baked oatmeal with even more nutrients by adding in chia, hemp, or flax seeds.

Serving suggestions

This oatmeal recipe makes the perfect grab-and-go breakfast but you can also dress it up and serve it as a delicious sit-down breakfast! Try drizzling it with peanut butter, topping it with Greek yogurt, or topping it off with strawberry sauce!

You can also bulk your breakfast up with all your favorite breakfast recipes. Serve it alongside yogurt parfaits, peanut butter banana smoothies, whole wheat pancakes, bacon and eggs, you name it!

    I used quick oats the first time I made this & it was really great. However, to make it healthier (I thought) I changed the oats but instead of regular oats I bought steel cut. I just read that’s not ideal for this recipe & I’ve found out how right that is. I think I’ll cook it longer tomorrow & I’ll add some milk to assist. Oh well………

  2. Teagan says

    I’ve made this recipe two times – one with raspberries and one with strawberries. And it was delicious both times! I think my new favorite simple breakfast. I’m about to try with peanut butter and chocolate for a bit of an indulgence!

  3. Michele says

    Made this morning with walnuts, blackberries and strawberries. Used applesauce in place of banana. Delicious 😋

  4. Sharlene says

    Question, Does the maple syrup have to be pure expensive maple syrup or can I use Mrs.Butter Worths or Aunt Jemimma ?

    thank you
