What is Baked Oatmeal?

Baked oatmeal is a warm breakfast casserole made from oats, milk, and other kitchen staples. Stovetop or instant oatmeal has a creamy porridge consistency, but baked oatmeal, like bread pudding, combines chewy, soft, and creamy all in 1 casserole dish. You can add berries for a juicy burst and walnuts for a crunchy topping. This breakfast recipe is a texture lover’s dream and your oven does all the work.

Basically, baked oatmeal is regular oatmeal with even more texture. If you’re looking for individual serving sizes, try my baked oatmeal cups. I love the apple cinnamon flavor!

You can bake oatmeal ahead of time and reheat it for a quick breakfast during the week. That’s exactly what I’ve been doing and the whole family, young daughter included, LOVES it. Busy parents certainly appreciate the convenience!

Video Tutorial: How to Make Baked Oatmeal


Gluten Free, Healthy, 1 Bowl Breakfast

This baked oatmeal combines simple and healthy ingredients and can be adapted for any allergies or flavor preferences. Stir the ingredients together in 1 large bowl, pour it into a greased baking pan, and bake. You need:

  1. Oats: I recommend whole old-fashioned style oats for a hearty and satisfying texture. If you eat gluten free, choose certified GF oats.
  2. Milk: Use the variety of milk you drink. This baked oatmeal is wonderful with whole milk, almond milk, oat milk, coconut milk, skim milk, and everything in between.
  3. Eggs: 2 large eggs, while adding protein, bind all of the ingredients together. Have an egg allergy? Use extra applesauce or mashed banana.
  4. Applesauce or Mashed Banana: Adds flavor and binds. You can use more of either to replace the eggs.
  5. Maple Syrup: I recommend pure maple syrup for the best flavor, but other unrefined sugars such as coconut sugar or honey work too. 1/2 cup sweetens the entire dish.
  6. Baking Powder: Lifts it all up!
  7. Melted Butter: A few Tablespoons of butter prevents the dish from tasting rubbery. Don’t replace with a non-fat alternative. Melted coconut oil is a wonderful dairy-free substitution.
  8. Vanilla, Cinnamon, & Salt: Each add sweet satisfying flavor.
  9. Berries: I asked, you told, and I’m delivering! Add some fruit for flavor, texture, and all-around deliciousness. Replace with chopped banana, apple, peaches, pears, raisins, dried berries, chocolate chips, or even a spoonful of your favorite nut butter.

For the BEST baked oatmeal texture: use whole oats and don’t over-bake! You want a deliciously soft & moist spoonful.

Ok let’s recap…

This Baked Oatmeal Is:

  • Prepped in 1 bowl
  • Made with unrefined sugar
  • Not overly sweet
  • Packed with fruit
  • Warm & satisfies for hours
  • Soft, chewy, & creamy
  • Adaptable for flavors, allergies, etc

Plus it requires minimum effort– just what our mornings need!

Complete your breakfast! Serve baked oatmeal with Greek yogurt, fresh fruit, scrambled eggs, sunshine smoothies or smoothie bowls, breakfast sausage, or my 110 calorie crustless veggie quiche. (–> also simple, healthy, & gluten free!)

Craving Pumpkin Baked Oatmeal?

I love turning this into pumpkin baked oatmeal! Here’s what I usually do: Reduce milk to 1 and 1/2 cups, remove the applesauce and 1 egg and replace with 3/4 cup of pumpkin puree, add 1 and 1/2 teaspoons pumpkin pie spice, keep the cinnamon in the recipe, leave out the berries and replace with chopped nuts, chocolate chips, dried cranberries, or leave plain. You’ll love my pumpkin baked oatmeal cups, too.

Description

This baked oatmeal combines simple ingredients that can be adapted for any allergies or flavor preferences. It’s like bread pudding for breakfast– creamy, soft, chewy, and delicious all in one! Make ahead and enjoy all week long. Try my baked oatmeal cups, too!


Ingredients

  • 1 and 3/4 cups (420ml) milk (dairy or nondairy)
  • 2 large eggs*
  • 1/2 cup (120ml) pure maple syrup*
  • 1/4 cup (60gunsalted butter, melted and slightly cooled*
  • 1/4 cup (60g) unsweetened applesauce or mashed banana
  • 3 cups (240g) old-fashioned whole oats*
  • 1 teaspoon baking powder
  • 1 teaspoon ground cinnamon
  • 1 teaspoon pure vanilla extract
  • 1/4 teaspoon salt
  • 1 and 1/2 cups mixed berries, fresh or frozen (do not thaw)*
  • optional for topping: 1/2 cup chopped walnuts or pecans

Instructions

  1. Adjust the oven rack to the lower third position and preheat the oven to 350°F (177°C). Spray a 9×9 inch or 11×7 inch baking pan with nonstick spray. Any similar size or shape pan works, though 8×8 inch would be too small. See recipe note for 9×13 inch pan.
  2. Whisk all of the ingredients together in 1 large bowl. Pour into prepared baking pan. Top with nuts, if desired. (Or stir into the oatmeal.) Bake for 35 minutes or until the center appears *almost* set, which gives us a soft oatmeal as pictured above. For drier and more solid baked oatmeal, bake until center has set.
  3. Cool for 5 minutes before serving. Spoon or slice and serve with yogurt, if desired. Cover leftovers tightly and refrigerate for up to 1 week.

Notes

  1. Make Ahead Instructions: Bake the oatmeal, cool completely, and store in the refrigerator all week for easy breakfasts. Reheat in the microwave or cover and bake in a 350°F (177°C) oven for 10 minutes. To freeze, bake and cool oatmeal. Cover tightly and freeze for up to 3 months. Thaw in the refrigerator or at room temperature. Warm to your liking. I love cutting the cooled baked oatmeal into bars or servings and freezing them individually for a quick breakfast to thaw. Wrap each in plastic wrap and place in a large freezer bag or container.
  2. Don’t: Do not make oatmeal batter ahead of time. The oats will soak up all the liquid! Whisk it all together, then bake right away. See make ahead instructions above for alternative.
  3. Eggs: Eggs bind the casserole and add wonderful flavor. If needed, you can replace the eggs with 1/3 cup unsweetened applesauce or mashed banana.
  4. Sugar: I recommend pure maple syrup because the flavor is outstanding and the baked oatmeal is extra moist! You can also use packed brown sugar, coconut sugar, or honey.
  5. Butter: What wonderful flavor! The baked oatmeal can taste rubbery without it. Don’t replace with a non-fat alternative. Melted coconut oil is a wonderful dairy-free substitution.
  6. Oats: Whole oats give you the best texture. Quick oats soak up more moisture and dry out the baked oatmeal. If using steel-cut oats, soak the oats in the milk for 20 minutes, then stir in the rest of the ingredients. Add a few extra minutes to the bake time.
  7. Add-ins: Instead of berries, try the same amount of peeled chopped apples, peaches, pears, bananas, or other fruit. Or 1 cup chocolate chips, dried cranberries, nuts, or raisins.
  8. 9×13 inch Pan: Double the recipe for a 9×13 inch pan. The baked oatmeal will be extra thick and require at least 10 extra minutes in the oven. Tent with aluminum foil if the edges are browning too quickly.

    I love your recipes, Sally! Would steel cut oats work in this recipe?

    1. Stephanie @ Sally's Baking Addiction says:

      Hi Melanie, You will want to soak them first. See recipe note #6 for details.

  2. Such a big fan of your blog, Sally! I’m craving a cranberry orange oatmeal bake for Thanksgiving weekend with my leftover fresh cranberries – would you recommend replacing some of the milk with orange juice? I’m not sure if it will lose some texture. I definitely will add orange zest 🙂

    1. Hi Vanessa, that sounds delicious! Try replacing 1/2 cup of the milk with orange juice, add a little orange zest, and use about 1-1.5 cups fresh cranberries. Actually canberries are quite tart, so you may want to stick with just 1 cup.

  3. MARGARET ROSE CROW says:

    Love this recipe, can barley be substituted in place of the oatmeal? I have some I need to get rid of.

    1. I haven’t tested this recipe with barley, but I fear it wouldn’t soak up quite enough moisture. I recommend soaking it in the milk for at least 1-2 hours before adding the rest of the ingredients. Let me know if you try it!

      1. Absolutely loved it. Made it with apples and walnuts instead of the fruit and added a pinch of nutmeg. Big hit! Planning to try with mashed bananas (instead of the egg) and chocolate chips for the next round! Thank you Sally for this gem.

  4. Hi, Sally!!

    I’m wondering if you have an overnight oatmeal recipe you would be willing to share?

    I love your blog! I’m too afraid to try any other recipe that is not from your site!

    1. Stephanie @ Sally's Baking Addiction says:

      Hi Vena, No we do not. Let us know if you find a good one!

  5. delicious! Hard to search for b/c of the name though.

  6. I love how versatile this recipe is! I’ve made it dozens of times and it’s always amazing. To give it a “holiday vibe” I made it today with applesauce, diced apples, craisins, walnuts, the zest of an orange, and a squeeze of its juice and it was absolutely delicious.
    Thanks for a great recipe!

  7. Made this today. Came out real good. I topped it with sauteed apples with some brown sugar. Yum.

  8. Once again I’m making this delicious oatmeal dish.
    Before Covid my family would get together for Sun brunch. This was always one they requested. So versatile with different fruits and nuts. Now we do “drive up” brunch, and this is still # 1 requested dish!

  9. How long does this need in the microwave to warm?

    1. Stephanie @ Sally's Baking Addiction says:

      Hi Gemma, It really depends on if you are reheating a small piece or entire pan, and the strength of every microwave is different. If reheating one piece I usually start with 30 seconds and check it and then add more time if I want it to be warmer.

  10. I have made this dozens of times at this point. I add a bit more fruit! Sometimes I bake it in a cake pan, sometimes muffin tins. Always freeze leftovers. It is a staple recipe for my breakfast, so easy, healthy and delicious. It is a must make!

    1. Trina @ Sally's Baking Addiction says:

      So happy you love it!

  11. Have been searching for a recipe that is similar to Collectivo and former restaurant Heinemann’s – this is it!!! Dollop of vanilla bean yogurt and fresh berries- delicious!!

  12. Veronica Menendez says:

    This was so easy! And now we have breakfast (or lunch, or snack) for the week! Toddler approved, too!

  13. Can you use GF oats? Does it change the taste or texture?

    1. Lexi @ Sally's Baking Addiction says:

      Hi Kayla, gluten-free whole oats work great in this recipe. Let us know if you give it a try!

  14. I don’t have an oven and rely on a crockpot instead – do you have a crockpot conversion time?

  15. Sally, this recipe!!!! SOOOOOO GOOD! Better yet, my 2 year old boy made it for me! Ok, I measured it all out for him. BUT get put everything in the bowl and mixed it! He even sprayed the pan!!! You need to put a “kids in the kitchen” filter on your website and put this one on it!!!

  16. Hi Sally

    Thanks for this. Delicious.

    Can I add protein powder to the recipe?

    Thanks again

    1. Lexi @ Sally's Baking Addiction says:

      Hi Joanne, we haven’t personally tried that, but we can’t see why not. Let us know if you give it a try!

  17. I don’t like regular oatmeal but this was delicious. My husband loved it. Will make all the time now.

  18. I can never eat any type of oatmeal for breakfast, unless it’s in a cookie, but I made this for my breakfast today and love it!! Now I have breakfast for a few days this week. I need to add more protein and whole grains to my diet due to intense physical activity, and this will help me get started in the morning! Thank you.

  19. can you use quick oats too?

    1. Trina @ Sally's Baking Addiction says:

      Hi Teresa, we recommend less baking time if using quick oats, maybe by just a few minutes. Otherwise it will be too dry

  20. Hi Sally! I just made this healthy and delicious baked oatmeal and I would definitely make it again! So easy to make and healthy! I’m looking forward to having this at work as a snack/breakfast. Thanks for the recipe!

  21. Hi Sally,
    Made this for the second time, always delicious! So great on a cold winter day with a cup of tea. This recipe is what will get me through the next three months 🙂

    Thanks,
    Kim

  22. Outstanding!!! Used toasted pecans and chocolate chips. Yum! There are so many possibilities for mix ins! Can’t wait to try and eat them all! Thanks!

  23. This is a great recipe! I’ve made it several times. My favorite add-ins are chopped apples and walnuts. It’s nice to have leftovers to enjoy an easy to make breakfast throughout the week.

  24. Is this a solid like a granola bar that can be eaten out of hand?

  25. I’ve made a lot of different clean oatmeal bakes and this is BY FAR the BEST recipe. It will definitely be my go to!

  26. Any suggestions on how to adjust this recipe to add a nut butter without altering the perfect consistency? We’ve made numerous fruit variations and the pumpkin one and loved them. Wondering how I could make a peanut butter + apple or almond butter + berry version. Thanks for any help!!

    1. Hi Rebecca! I’m so glad you enjoy this baked oatmeal. We make it with peanut butter or almond butter all the time. I usually reduce the butter down to 2 Tbsp and add 1/2 cup of our favorite nut butter. Same bake time.

  27. If I want to add more protein to this recipe, would it be okay to add in vanilla protein powder?

    1. Trina @ Sally's Baking Addiction says:

      Hi Courtney, we haven’t tested it but would love to hear how it goes for you!

  28. Tina Sawmiller says:

    We really like this receipe. I have made it 3 times already. Our favorite fruit mix is apples and blueberries.

  29. Could this be baked in a muffin tin for premade portions? How would you change the baking time?

    1. Lexi @ Sally's Baking Addiction says:

      Absolutely — follow the instructions for our Baked Oatmeal Cups. Enjoy!

  30. Just took this out of the oven…it is so delicious on a cold, windy day. I had mine with vanilla yogurt and hubby had it without. Made this one with blueberries and strawberries, can’t wait to try it with bananas and chocolate chips. Love Sally’s recipes.
