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.

One of my favorites! I almost always have frozen berries, oatmeal, and yogurt. I love whipping this up for my family. It feels like a perfect farmhouse breakfast! Something about that warm bake with a cold yogurt just gets me.
It really is so easy to mix and bake. I’m happy you and your family love it!
I have made this several times- the first was just as the recipe says – then substituted the berries for sautéed cinnamon apples. The frozen berries took much longer to cook than 45 minutes and produced quite a bit of moisture. Thanks for the recipe that can work with any fruit, or none at all!
Hi Mandi – Love the variations you made with this baked oatmeal recipe!
I can’t remember how many times I made this. It’s so cozy and just eating it makes me happy. I usually have more than one portion.
Must try recipe!
Hi Maysara – It really is such a comforting breakfast to enjoy!
This is so good! It is easy to make and excellent meal prep. Just warm up in microwave. Serve with a dollop of vanilla yogurt. It freezes well also.
Thanks so much, Debbie. I’m glad you enjoyed it!
My family and I love this! It doesn’t spike my mom’s glucose as high as the usual oatmeal I make her. I love using peaches, strawberries and blueberries! My husband isn’t an oatmeal fan but eats this one! Thank you for so many excellent recipes!!
You’re more than welcome, Denise! I’m so happy you and your family are enjoying my recipes, including this baked oatmeal. :)
Supper choice for a recent girls brunch! I love walnuts l, mixed frozen berries and pure maple syrup in my version 😍
Great idea serving this up for a girls brunch! I’ll have to do that with my friends next time. :)
Just did this last night and it turned out great. So easy to do.
Hi Maria – Happy to hear you loved this berry baked oatmeal!
Delicious! I used raspberries instead of mixed berries and it was so flavourful!
Hi Ainsley – Sounds great with raspberries!
I made this on the weekend, the family loves it. I think everything I make of Lisa’s is a winner!
Hi Janet – I’m so glad everyone loves this berry baked oatmeal!
Can I premake it tonight and put in oven tomorrow?
Hi Amanda – No, I would not recommend pre-mixing everything and letting it sit. But you could make it completely tonight, then just reheat tomorrow.
Delicious! Had this as part of our Thanksgiving breakfast. It was so good. My picky family of 5 all agreed. This is definitely going to be in my rotation year round!
Hi Amy – I’m happy to hear your whole family loved this baked oatmeal. Happy Thanksgiving!
I’ve made this recipe a couple of times and shared it with family. It is Awesome! It’s a wonderful balance of sweet and savory and it does not spike my sugar and it keeps me satiated until lunch! So grateful for this and all of your recipes Lisa!!
