Healthy baked oatmeal

It’s difficult to find a comforting breakfast that’s easy, healthy, and not just… eggs.

This baked oatmeal checks all the boxes and, best of all, it tastes REALLY good. Today I’m persuading you something you never knew before: you need baked oatmeal in your life!

Baked oatmeal recipe

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 Noelle included, LOVES it. I certainly appreciate the convenience!!

ingredients in 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.

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 (60g) unsalted 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.

  1. I made this yesterday so my husband can easily take a piece to work in the morning. It’s delicious! I thought I had exhausted all the breakfast possibilities long ago. Thank you, Sally, for a new idea for breakfast!

  2. I just made this recipe and it turned out soooo good! I followed the recipe exaxtly- I used whole milk, frozen berries and topped with unsweetened shredded coconut. I broiled it for one minute at the end to get the coconut extra toasted. This is a great recipe for cleaning out the pantry, and using up milk that is about to expire. I feel full and ready for the day! Thank you Sally 🙂 I love making your recipes, it brings me so much joy!

  3. When I came across this recipe I knew I had to make it ASAP! I start my Spring semester next week and I’m always looking for something quick, healthy, filling, and delicious in the morning. This recipe is all of those things, so I’m excited to add this to my breakfast mix!

      1. You should freeze what you don’t want to eat right away. It would probably be to dry if you changed the recipe to that extent.

  4. I made a double batch and took it to work. I followed the recipe and used half fresh and half frozen blueberries. My co-workers gave the recipe great reviews and asked for the recipe! I served it warm with Greek Yogurt. The one comment I did get…it would have been great to have Maple Syrup to drizzle it over the Yogurt. A keeper for the recipe files.

  5. Delicious! I made it today with fresh strawberries, frozen raspberries and frozen blueberries that we picked last summer. Amazing! The whole family loved it. Used 1/2 dairy and half cashew milk.

  6. I made this baked oatmeal this week with frozen mixed berries and my daughter and I have been really enjoying having it for breakfast. It is so good and a nice change up from my regular breakfast of cold overnight oats.

  7. I made this last night and had my first serving of it for breakfast this morning. Delicious! Nice to know I have a new delicious breakfast option for work mornings!

  8. When this oatmeal came out of the oven it looked impressive and it tasted really delicious. I stored the leftovers in the refrigerator and have eaten on it for 2 more mornings. I have to say, each morning it got progressively dry and a bit undesirable. I would recommend eating it up on day 1 or day 2 at the latest. I will keep this recipe with that in mind. Thank you for sharing it Sally!

  9. Hi Sally!

    I just baked this and it smells absolutely amazing! Thing is, I cut into it (after letting it cool for 10 mins) and it was soggy inside. Still tastes pretty good, but definitely looks nothing like yours 🙁

    Could this be because there was too much liquid? I used two small-ish to medium eggs and the recipe calls for two large. I added extra mashed banana to make up for the eggs and may have overcompensated.

    Any suggestions/help to make my second attempt a success? Looking forward to hearing from you! 🙂

    Ps. Thank you for your endless wonderful recipes!

    1. Hi Lauren! There could have been extra moisture from the added banana. Did you use whole oats? Bake for a little longer next time if desired.

  10. Thank you, Sally, for this deliciously awesome recipe. I made it this morning as written with fresh blueberries and strawberries and loved every mouthful. My hubby enjoyed it as well. I love cereal with fruit for breakfast, but this is so much better. Next time I’m thinking bananas and brown sugar instead of maple syrup would be yummy.

    In this crazy world we live in, it is wonderful to have you there to distract us with delicious adventures in the kitchen. Thanks so much. You are an inspiration.

  11. I was afraid to make this because I’ve tried others and I hated them. I cannot believe how surprised I was! It is so good and it really keeps you full all morning! I was so skeptical, but as my daughter said , it was a Sally recipe, so of course, I wasn’t disappointed!

  12. With this snowy weekend, I knew I had to make this baked oatmeal. I’ve made other baked oatmeal recipes and found it wildly disappointing, but I knew a Sally’s baked oatmeal would be different. And I was right. I prefer a firmer texture so I baked it for a full 45 minutes. Turned out to me more like soft oatbars. Not very sweet, but that’s kind of the point. Great option to make breakfast for the week ahead. Super easy and very healthy.

    1. Thank you, I was hoping to find something about cooking it for longer. I do not like oatmeal because of the texture, too soggy. So am kind of afraid to try this recipe, but you say it came out like soft oatbars, which I can definitely get behind!

  13. Sally this is absolutely delicious! Warmed me up on this -7 degree morning. Love getting your emails to see what is new. Also, Two Peas has some great variations on this to try as well…Zucchini Bread Baked oatmeal?

  14. I made this with apples and craisins because that’s what I had on hand. It was delicious. I’m looking forward to making it with fresh berries. I had been making and freezing steel cut oats regularly, but I’m going to switch to this recipe. It has a much better texture and flavor.

  15. I made this recipe this morning and it was delicious however I felt it needed to be more sweet but maybe that’s because I have a sweet tooth. Will make again!

  16. I just baked and mine came out very soggy and mushy as well. I even baked an extra 10 minutes and turned heat up 5 degrees. I was hoping for some chewy texture (chewy granola like) like the pictures look. I used large eggs and followed recipe exactly. Next time I will cut back milk and add a little brown sugar to make it a little sweeter. I used frozen berries. I wonder if that where extra moisture came from.

    1. Hi Amanda! The center of the baked oatmeal is very soft– not chewy at all. I tried to explain that, so I’m sorry if you were expecting differently! Feel free to bake for longer if you want your baked oatmeal more “set” especially if you are using frozen fruit. 🙂

  17. Today I made Sally’s new oatmeal breakfast dish using brown sugar, banana, and slivered almonds on top. Easy to put together out of everything I keep on hand and baked up perfectly. As a huge oatmeal fan (even for dinner sometimes) I will be making this often. Great idea to make when out-of-state family come to stay. Thank you!

  18. Sally, thanks so much for this! I’m a furloughed fed who’s on the Shutdown Diet (aka scrape through your pantry for all the stuff you forgot you had and find some way to throw it all together). This was delicious and cheap and came out perfectly. Thanks for such a yummy way to help me stretch my dollars. 🙂

  19. Oh my word – so good! I’m currently eating a bowl of this right now and it’s delicious! It was so easy to toss together and now I have at least a week of breakfasts. I used a cup of frozen raspberries and 1/3 a cup of chocolate chips. Thanks for the recipe!

  20. I’ve eatin many a bowls of oatmeal. As a kid my dad would make oatmeal with raisins for myself and sisters before school. I can’t say I was a big fan. I’ve made oatmeal and changed over to steel cut oats to be healthier. I made this recipe and used fresh strawberries and frozen blueberries. It was amazing! The best oatmeal by far. It had lots of flavour and was delicious! It was convenient to make and heat up for my early mornings. Thank you Sally! I found your site a few years ago and you have been my go to. When I get asked for a recipe I’m always saying “It’s a Sally!”

  21. This was sooo good! Been wanting to do healthier, more filling breakfasts for my family and this is definitely going into the regular rotation. I added a handful of chocolate chips for the kids but it totally doesn’t need it and I’ll probably leave it out next time. The kids loved it so much they wanted it for snack after school, breakfast tomorrow and in their lunch lol. Thanks for a great recipe!

  22. The perfect amount of sweet w/ fresh blueberries & raspberries. I used skim milk & think this is a delicious, healthy recipe. I will definitely make again, thank you!

  23. I loved how easy this was to pull together (I actually mixed it and put it in the oven while I was making your lightened chicken noodle soup) and how delicious it turned out. Such a great breakfast to prep for the work week. Thanks for the recipe!

  24. I made this recipe over the weekend and both my husband (who’s not a big oatmeal eater) and I loved it!! The recipe is a keeper, looking forward to making it again. The leftovers the next morning tasted even better. I already passed on the recipe to my sister who also made it and loved it. Thanks for an awesome recipe!

  25. Hi!
    Can you pls advise what size casserole dish you used? Counting my macros and I want to be aure to enter the macros correctly!
    Thanks
