The Perfect Make-Ahead Breakfast
I’m always looking for healthy breakfast ideas that will give me energy to get through the day. I work long shifts in the ER so keeping my stamina up throughout the day is really important.
I like to pack my own meals on work days. That way I don’t have to rely on what the hospital cafeteria is serving up.
This baked oatmeal is the ideal breakfast for me because I can bake it on the weekend for my whole family. Then I can take the leftovers to work the rest of the week.

Packed with Superfoods
This recipe is packed with superfoods! Superfoods are foods that are rich in compounds that have the power to positively affect our health, ward off disease, and increase longevity.
- Oats are nutritious whole grains that are packed with fiber. Fiber helps keep things moving along smoothly in our intestinal tract. A diet high in fiber also helps reduce cholesterol, regulate blood sugar levels, regulate blood pressure, and lower your risk of heart disease.
- Blueberries are superfoods too. They provide vitamin C, fiber, and powerful disease-fighting antioxidants. I love using blueberries in popsicles, smoothies, and fruit crisps.
- Walnuts are also packed with a wide variety of important nutrients. Did you know that one ounce of walnuts has 2.5 grams of the omega-3 fatty acid alpha-linolenic acid (ALA), 4 grams of protein, and 2 grams of fiber? This combination helps keep you feeling full and satisfied.
How to Make Blueberry Apple & Walnut Baked Oatmeal
Baked oatmeal is so easy to make! Here are the steps. Scroll down to the recipe card below for full recipe amounts and instructions.
- Mix your dry ingredients together (rolled oats, baking powder, cinnamon and salt).
- Mix your wet ingredients together (milk, Greek yogurt, egg, maple syrup, coconut oil or butter, and vanilla extract). A lot of recipes just use milk but I like to add some Greek yogurt to my dish. This adds a nice boost of protein.
- Scatter some blueberries, chopped apple, and walnuts around the bottom of an 8x8-inch baking dish. Top them with the dry ingredients. Then pour in the wet ingredients.
- Press it all down so that the dry ingredients are submerged in the liquid. Finally, top the dish off with some more blueberries, apples, walnuts, and a dusting of cinnamon, and pop it in the oven.
In 40-45 minutes, you’ll have a delicious, hot, baked breakfast dish that’s bursting with flavor. And your kitchen will smell delicious!
Baked Oatmeal Has Endless Variations
Once you get the basic recipe for baked oatmeal down, you can make endless variations using your favorite ingredients.
In the summer, you can make baked oatmeal with sweet summer berries or luscious stone fruit like plums, nectarines, apricots or cherries. In the fall, you can make a batch with apples and cranberries.
My Peach Baked Oatmeal pictured here is a reader favorite that you must try! Warm, cinnamon-infused oatmeal is studded with sweet peaches and topped with thick, creamy vanilla yogurt. Yum! It's super easy to make and your whole family will love it!
How To Serve This Dish
I love to eat baked oatmeal warm with a some milk drizzled on top or a dollop of Greek yogurt and maple syrup. But it’s also really satisfying eaten cold, straight out of the fridge the next day (or as a midnight snack if you can’t wait until morning!).
A hearty and satisfying breakfast that’s bursting with flavor, whole grains, protein, fiber, and antioxidants. What more can you ask for?

- Whisk the milk, yogurt, egg, maple syrup, coconut oil and vanilla together in another bowl.
- Arrange 1 cup blueberries and 1 cup chopped apple in the bottom of the prepared baking dish. Scatter the oat mixture evenly on top.

This looks amazing. I need to know the serving size for that amount of calories. I am trying to maintain my loss of 60+ lbs. How many servings in the recipe! Can't wait to try it.
Thanks
Dr. Sonali Ruder says
Good for you! Yes, the recipe makes 8 servings so one serving is 1/8 of the dish. I hope you enjoy it!
Shanna says
I made this with a few adjustments It is great!
Changes:
1.5 times apples, blueberries, walnut
Agave syrup instead of maple
I can’t believe its not butter instead of butter
Added: Garam Masala and lemon juice
Dr. Sonali Ruder says
Thanks for your review, Shanna! The addition of garam masala is so interesting! So happy you liked the dish 🙂
Nancy says
This is delicious. Love it. Will definitely make it again!
Dr. Sonali Ruder says
That’s great! I’m so happy you liked the dish, Nancy! Thanks for leaving a comment 🙂
Patricia says
This recipe is awesome. I hate oatmeal, but with all the fruits,nuts you really don't taste it.
Can you freeze this ? Or will it be soggy
Dr. Sonali Ruder says
I’m so happy you liked the recipe, Patricia! Yes, this dish freezes well. You can freeze the whole thing or cut it into pieces and freeze the individual portions. Thanks for leaving a review!
Nancy says
This was delicious. I shared with a friend who you were one of the recipe afterwords and is planning on making it for her mother. Are used to nonfat milk and substitute sour cream for the Greek yogurt because that’s what I had. I also used pecans instead of walnuts. Really delicious
Dr. Sonali Ruder says
Thanks for your comment, Nancy! I'm so happy you enjoyed the recipe. I've never used sour cream before- I'm glad it worked out well. The pecans sound like a delicious substitution!
Judy Johnson says
I have another baked oatmeal recipe without fruit in it and it calls for 1/2 c. of brown sugar. I think I will try that the next time I make this and omit the maple syrup. I like my baked oatmeal a little sweeter!
Dr. Sonali Ruder says
Sounds good! The great thing about this recipe is that you can easily adjust the amount of sugar to your taste. I hope you love it!
Kim says
Could you omit egg & use something for a replacement? I really want to make this, but we cannot have eggs.
sonaliruder says
Yes, you can use a flax egg. To make a flax egg, mix 1 tablespoon ground flaxseed with 3 tablespoons water in a bowl. Let it sit for 5 minutes and then use in recipe to substitute for 1 egg. Let me know how it goes if you try the recipe!
Fran says
Made this for breakfast this morning and it was delicious! So good, that we had a small piece for dessert tonight with a little vanilla ice cream!
Beth Nicol says
looks really good. I'm wondering if I could cut way back on the maple syrup. I've been on a no added sugar regime and that sounds awfully sweet! (I do love maple syrup, tho) I'll give it a try because this looks so good!
Dr. Sonali Ruder says
Yes, you can definitely leave out the maple syrup 🙂
KERRY BUSBY says
You may want to try sugar-free maple syrup. I buy Maple Grove Farms and it is awesome!
Dr. Sonali Ruder says
Great suggestion!
Rifat says
Thank you so much for this enlightening post, I have significantly got some thing right here and I will bookmark this page for your next upcoming post.
Janet says
I see a dietation for a variety of issues and she gave me this recipe - as it sits in the intersection of something healthy and suitable for an adult with the palate of a 12 year old. Also, it helped me discover that I actually LOVE fresh blueberries - so thank you so much! Very delicious!
Anna says
Can you use frozen blueberries or will that be too liquidy/messy?
sonaliruder says
Yes, frozen blueberries will work!
Milly says
Delicious!!!
I made this with several changes:
• I put it in the slow cooker for four hours on low and it came out perfect.
• I left out the sweetener and it was sweet enough in my opinion.
• I forgot the oil.
• I used 1 1/4 cups lite coconut milk in place of milk and yogurt.
• I added extra blueberries to the top.
• I halved the amount of walnuts.
It was so good that my sister who hates oatmeal said she could even stand it. I will be making it again!
Thank you very much!
sonaliruder says
That’s great! So glad you liked it!
Mich says
O.M.G.....I love love love this recipe !!!! It's my new fav .This is the second time I have made it ..I use a little less syrup and use a red delicious apple. Otherwise I make exact recipe 😋It is The Best !!!!
sonaliruder says
Thank you!!! So happy that you love it!
Catherine says
Is it possible to make this dairy free by using coconut yoghurt instead of Greek? I’ve made this many times and it’s delicious I don’t want to miss out now I’m dairy free ;( Thanks - Cat
sonaliruder says
I’ve never tried it but it should work fine. Otherwise, you can leave out the yogurt and add extra milk.
Pat says
How much extra milk if not using yogurt?
Dr. Sonali Ruder says
I would use the same amount, 1/2 cup.
