For oatmeal fans this berry baked oatmeal is another delicious way to enjoy oats for breakfast! The top is slightly golden while the inside is soft and loaded with a pretty sweet berry assortment.

Just when I thought overnight oats or the classic stovetop oatmeal were my favorites, this berry baked oatmeal proves its worth. Especially when you’ve got more than one person at the breakfast table! It’s easily sliceable into 6 portions and can be jazzed up with a quick dollop of creamy yogurt.

So yes I’d say this healthy baked oatmeal recipe is another perennial winner for breakfast meal prep. Just warm it up (with optional toppings) and enjoy it with a hot cup of coffee or matcha to get your day started on a good note!

Berry Baked Oatmeal Recipe Ingredients

Think of this as a breakfast casserole dish, but in oatmeal form! Here’s what you’ll need.

  • Oats: Stick with old-fashioned rolled oats for the best texture. And if you’re gluten-free like me, make sure to always grab a bag of certified gluten-free oats!
  • Berries: I’m using frozen mixed berries for this recipe. But you could also use fresh berries, especially when they’re in season!
  • Nuts: Sliced almonds help to add a bit more texture and crunch to the oatmeal base.
  • Liquid Ingredients: A combination of eggs, maple syrup or honey, vanilla extract, melted butter or oil, and milk (dairy or dairy-free) binds the oatmeal together.
  • Baking Essentials: A little baking soda, salt, and a dash of cinnamon finishes it off.

If you want to swap some of the ingredients…

  • Switch up the fruits. Instead of berries, you can try using any other frozen fruits of your choice! I highly recommend mangos, banana, or peaches (I have a peaches and cream version in my cookbook!).
  • Use different nuts. If you’re not a fan of almonds, you can also use chopped walnuts, pecans, or your favorite nuts.

How To Make Baked Oatmeal

Before starting, grab a 9-inch square baking dish. Then gently grease the inside so the oatmeal doesn’t stick when you’re scooping it out!

Mix the dry ingredients. In a large bowl you’ll stir together the oats, sliced almonds, cinnamon, baking soda, and salt.

Stir the wet ingredients together. In a separate bowl, whisk together the milk, honey, eggs, butter, and vanilla.

Combine everything together. Pour the wet mixture into the dry, add the frozen berries, and stir everything together. If you start to notice the berries turning the liquid purple, that’s totally fine!

Prep and bake the casserole. Transfer the mixture to the baking dish and top it with extra berries and almonds. Then bake for 40 to 45 minutes at 375°F (190°C). Make sure to let it cool a bit before slicing!

Storage Tips

  • To store: Store any leftovers in an airtight container in the fridge for 4 to 5 days.
  • To freeze: Yep, baked oatmeal is freezable! Make sure to slice the oatmeal into portions before storing them in a freezer-safe container for up to 3 months. This will make reheating a breeze!
  • For reheating: Thaw each frozen portion in the fridge overnight. Then bake uncovered with aluminum foil in a 350°F(180°C) oven for 15 to 20 minutes. You can also reheat in the microwave for 1 to 2 minutes, or until warmed through.

  1. Hi Lisa,

    Is there a way to turn this into power bars? I would love to have a take with me everywhere version in a bar form just to mix things up. :)5 stars

    1. Hi Alan – I haven’t tried, but I’ll keep this in mind for a future recipe! I do have a chewy granola bar recipe though you can try :)

  2. Oh soooo yummy! I made it with frozen mango and berries, and almond milk. I can’t believe how easy it was to make, too!5 stars

  3. Absolutely delicious. I used chopped walnuts and almond milk.
    Fresh blueberries, fresh strawberries, and fresh raspberries as I had them in the fridge.
    Need some dinner ideas that don’t take alot of time to make
    Thanks so much. Happy 2024!5 stars

    1. Hi Eleni – Happy to hear you love this baked oatmeal! As for quick dinner ideas, I have a category for 30-minute or less dinners in the navigation :)

  4. Hi Lisa
    I cannot wait to try out this recipe. Quick question: can I use quick cooking oats instead? Or does it have to be OF rolled oats?

    1. Hi Lareena – For the best texture, rolled oats are preferred. Otherwise, it will be very mushy with quick oats.

  5. This is my favorite go to breakfast. I make this every week. I do add a little stevia sugar for extra sweetness….5 stars

      1. Another easy, quick & delish recipe from Lisa! It’s a nice change from just a bowl of oatmeal and would be great as a guest brunch option.5 stars

  6. I have made this recipe several times, is super delicious and convenient for an easy breakfast.
    I added an unsweetened shredded coconut and the flavor is amazing! The toasted coconut with coconut oil and coconut milk… Yummy!
    Thank you Lisa.5 stars

  7. I went a little off-grain here and made this recipe with Fall apples — they’re in abundance here in Kelowna, B.C., Canada. I swapped almonds for pecans and used half and half milk/cream, as that was all I had. And, wow, it’s almost like having apple pie and ice cream for breakfast, without all the refined sugar. Add a large dollop of Greek vanilla yogurt on top — decadence for the day! Great to warm up and indulge for a few days. Recommend!5 stars

  8. Did not like the gelatinous texture created by the egg, and when using a tart fruit it’s going to need more sweetener. Won’t be making this one again.1 star

  9. I just made this recipe this morning. I followed the recipe exactly and it turned out as expected. It was crisp on the outside and soft and similar to bread pudding on the inside. I ate it plain with a cup of coffee and it was perfect!5 stars

  10. I love this recipe and have made it several times. I am curious if this can be made the night before like overnight oats and then baked the next morning?5 stars

    1. Hi Sarah – I have a peaches and cream flavor in my cookbook! But I’ll keep that in mind for introducing another fall flavor to the website. :)

  11. So delicious!! I used 1 cup quick oats and 1 cup Antient Grains from Trader Joe’s. I had cherries I had frozen earlier this summer so I used 2 cups of those and the last little bit of mixed berries I had. It tastes delicious!5 stars

  12. This is one of my go-to breakfasts. It’s really good. I freeze some of it and it’s still delish when I defrost and warm it up. I’ve added apples and peaches when I I didn’t have enough berries.5 stars

    1. Glad this recipe is coming in handy for breakfast meal prep! Also, congrats on the new baby, Sara :)

    1. Oh no! I have a feeling it didn’t cook all the way. Next time, try leaving it in for longer or bumping up the temperature a bit.

  13. I made healthy berry-baked oatmeal & it is so cozy & delicious. I topped mine with peanut butter & maple syrup.5 stars

  14. Berry Baked Oatmeal was a HUGE hit. It was easy to make, and the entire batch was gone before I knew it. Especially loved that it is packed with health benefits. I can’t wait to try the one in Lisa’s new cookbook that I just purchased, and which uses peaches.5 stars

  15. I have been eyeing this recipe for a long time, and I finally had the time to make it. Easy, delicious, and super healthy. I wonder how a less healthy version would turn out . . . with chocolate chips?5 stars

    1. I’ll have to test out a chocolate chip version! But, glad you enjoyed this berry version Amanda.

      1. Yep, baked oatmeal is freezable! Make sure to slice the oatmeal into portions before storing them in a freezer-safe container for up to 3 months. This will make reheating a breeze!

  16. This is SO delicious! And, it’s also super quick and easy to prepare. I added a few walnuts to the recipe as well. Thank you!5 stars

  17. I’ve made this recipe every week for several months. I love how versatile it is and have settled on my (current) favorite way with just a few modifications. I love it with walnuts, blueberries and combining sourdough discard with less milk. I find that using a cup of discarded sourdough and 1/4 of milk gives the oatmeal a n almost cake like texture and really holds it together well. I also use equal parts honey and maple syrup. This recipe is absolutely delicious reheated in the air fryer! I preheat the air fryer and heat it for 5-6 minutes at 380 degrees. So quick and easy! I double the recipe and make it in a 9×13 pan. Thank you so much for making meal prep so easy! My husband and I love trying so many of your recipes!5 stars

    1. Happy to hear you’re loving this baked oatmeal recipe! And good to know it reheats well in the air fryer :)

  18. Loving it!!! My kids and I are big oats fans. My kids loved it. Asked for seconds as well. We baked it together. Simple, easy to prep, and quick to bake. Will be my go recipe for breakfast!! Thank you so much!!5 stars

  19. I just made this and used oat milk…AMAZING! I also used brown sugar instead of maple syrup and it was so darn good. 5 stars
