blueberry banana baked oatmeal
$4.18 recipe / $0.52 serving

Will I ever get tired of baked oatmeal? Probably not. It's easy, cheap, deceptively filling, and I can cook it one day and then eat it throughout the rest of the week.

I love this version because I barely had to add any extra sugar thanks to the super sweet bananas. I used only 1/4 cup for the entire batch, and honestly, I probably could have cut that down to 2 Tbsp. Bananas are fantastic. The frozen blueberries were delightfully tart against the sugary bananas, which made them a perfect mate. If you're lucky enough to have fresh blueberries, this recipe is a great way to use them up!

If you've got a few extra bucks, adding some nuts would be a nice texture contrast (try walnuts or almonds)!

Total Recipe cost: $4.18
Servings Per Recipe: 6-8
Cost per serving: $0.52 (for 8 servings)
Prep time: 15 min. Cook time: 45 min. Total: 1 hr.

INGREDIENTS COST
1.5 cups (3 med) mashed bananas $0.75
2 large eggs $0.50
1/4 cup white sugar $0.04
3/4 tsp vanilla extract $0.21
1/2 tsp salt $0.02
3/4 tsp baking powder $0.03
2 cups milk $0.50
2.5 cups old fashioned oats $0.43
8 ounces frozen blueberries $1.70
TOTAL $4.18

STEP 1: Preheat your oven to 375 degrees. Mash the bananas in a measuring cup, starting with two or three and adding more until you have 1.5 cups of banana mash.

STEP 2: Combine the banana mash in the large bowl with the eggs, sugar, vanilla, salt, and baking powder. Whisk to combine. Add the milk and whisk again until smooth.

STEP 3: Stir in the dry old-fashioned oats. Lastly, stir in the frozen blueberries (keeping them frozen and stirring them in last helps prevent the entire mix from turning purple). Spray an 8x8 inch baking dish with non-stick spray and then pour in the oat mixture.

STEP 4: Bake in the preheated 375 degree oven and bake for about 45 minutes or until the top is golden brown and the center is no longer wet to the touch.

Serve warm or refrigerate until ready to eat. These oats can be quickly reheated in the microwave each morning for a quick, filling breakfast.

Blueberry Banana Baked Oatmeal


Step By Step Photos


mash bananas
Mash the bananas with a fork, starting with just a couple and adding more until you have 1.5 cups of banana mash. Try not to leave any large chunks. (last time it took me 4 medium bananas, this time only 3).

custard ingredients
Add the banana mash to a bowl along with the eggs, vanilla, sugar, baking powder, and salt. Whisk until smooth.

add milk
Next, add the milk and whisk again. It's a lot easier to make a smooth, cohesive mixture if you whisk the other ingredients prior to adding the milk. That's why it's done in two steps.

add oats
Stir in the dry oats. It's easier to stir them in with a large spoon than a whisk, but I didn't feel like dirtying another utensil.

frozen blueberries
I love having frozen blueberries on hand. They're a great addition to many dishes, are less expensive than fresh, and keep for quite a while in the freezer. I used half a bag for this recipe (and used the rest for my smoothie packs).

ready to bake
Keep the blueberries frozen until you add them so they don't bleed purple color throughout the oatmeal. Adding them at the very end helps this as well. Pour the blueberry oat mixture into an 8x8 inch casserole dish that has been sprayed with non-stick spray.

baked blueberry banana oatmeal
Bake for about 45 minutes at 375 degrees or until the top is golden brown and no longer wet to the touch in the center. I baked this oatmeal at 25 degrees higher than my other baked oatmeals to compensate for the little blueberry ice cubes floating around in it. It worked out well.

Blueberry Banana Baked Oatmeal
I like to eat mine with a little bit of cold milk poured over top. This makes for a very fast, very hearty breakfast every morning of the week!

I swear if it wasn't for you, my family would never eat real food! Cannot wait for your cookbook!!

This looks wonderful, I love the idea of baked oatmeal, I never would have come up with that on my own

Could we use a flax egg to vegan-ize it?

Beth M | August 17, 2012 at 12:39 PM

Suzanne - I tried that once and it did not turn out good at all. Although, I just mixed the ground flax in with the rest of the ingredients instead of letting them soak in water first. So, that may have been in the issue.

helping others | August 17, 2012 at 1:41 PM

this looks great. We'll have to try it!

Ryan | August 17, 2012 at 2:48 PM

Curious about using peaches instead of bananas for that classic peach-blueberry contrast. Think a fresh peach or 3 diced would work in place of the mashed bananas?

The REALLY Real Curious Crow | August 17, 2012 at 3:00 PM

SO, YAY! You've gotten me so addicted to baked oatmeal, this made my whole day. Can't wait for tomorrow morning. ;)

Anonymous | August 17, 2012 at 8:15 PM

Have you tried this with steelcut oats, by any chance? If so, did it turn out ok? For some reason oatmeal is somethung I fail at consistently, so i just want to see if you have any hints before I try it out with the steelcut oats. This seems delicious, by the way!

Patricia @ ButterYum | August 17, 2012 at 8:53 PM

Oooooh - excellent recipe!

Beth M | August 17, 2012 at 10:49 PM

Ryan - The first baked oatmeal recipe I made was peach blueberry, as a matter of fact! It uses yogurt in place of the mashed banana to add moisture.

Anon - Steel cut oats require quite a bit more moisture and a longer cooking time than old fashioned oats, so I think the recipe would have to be adjusted quite a bit to make it work. Without having done it, I can't say for sure what changes you'd need to make.

Vimitha Anand | August 18, 2012 at 2:09 AM

Nice delicious and healthy meal...

Mary | August 18, 2012 at 10:17 AM

Could you sub soy milk or juice for the milk? I want to share this with a friend who has can't use dairy. I made it this morning with the milk and it was amazing

Drop that Debt | August 18, 2012 at 10:21 AM

I just found your website, and it is an instant bookmark !! All of the recipes look amazing and I have a very strict budget, thank you so much for this.

Beth M | August 18, 2012 at 10:21 AM

Mary - Soy milk would be the best substitution. That way you'll still have that nice creaminess :)

Ash | August 18, 2012 at 3:42 PM

Love all of your baked oatmeal variations!

April was in CT now CA | August 19, 2012 at 1:52 PM

Just finished inhaling two bowls of this awesome breakfast, we loved it! I made baked oatmeal years ago and it was a dry, gross mess and I'm so glad I tried it again. I can see us having different variations of this every weekend. I used fresh blueberries and a little dash of cinnamon.

Michele | August 19, 2012 at 7:17 PM

Wow, this is fantastic! I will definately be making this again and again. I was so happy I saved those awful looking bananas. Much better than making banana bread with them!
Thank you.

Karly | August 19, 2012 at 10:33 PM

For the Flax egg, you use 1tbsp per 3 tbsp of water, mix it together, and refrigerate it for at least 15 minutes before adding it to something! I did it with the apple flax muffins and it turned out great!

This looks amazing!

Anonymous | August 19, 2012 at 11:05 PM

Just came across your site today and I'm loving it! I'm a vegan so I will make some adjustments, but all the veggie stuff looks amazing. I think I might try pureed applesauce with extra baking power in place of the egg for this one. It's what i do for muffins and cupcakes.

Anonymous | August 20, 2012 at 8:15 AM

I can't wait to try this recipe. Has anyone made it with quick oats or instant oats? If so, did it require any changes?

ChelleInMS | August 20, 2012 at 10:17 AM

I absolutely love your baked oatmeal recipes. I turned your banana nut bread into a fall harvest bread with apples, cranberries and walnuts! Keep them coming!

Alyssa | August 21, 2012 at 9:23 AM

I just made this and it was amazing! I used coconut milk in place of regular (we have a dairy allergy in the house) and it tastes heavenly...thanks so much for the recipe!! I have a feeling it will be made over and over again.

Can you freeze this?

Beth M | August 21, 2012 at 11:38 AM

Anon - This should freeze well.

Anonymous | August 21, 2012 at 3:09 PM

Since we dont use the measure "cup" over here in europe and i am not really familiar with baked oatmeals i am uncertain if i got the recipe right. how should the consistence be? when i saw the pictures i imagined it would be kind of crunchy, like those cereals one can buy but my first try is more soft or mushy almost like a pudding (it wasnt wet to the touch anymore :P).
still "eatable" but not the way i imagined it when i saw your pictures...

Beth M | August 21, 2012 at 3:16 PM

Anon - Yes, it is definitely a soft, pudding like texture. The oatmeal is basically baked in a custard mix (eggs and milk). If you like a crunchier oat cereal, maybe try this granola recipe? I hope you can still enjoy the baked oatmeal, though!

Anonymous | August 21, 2012 at 11:47 PM

good morning,
i think it is growing on me :)
will bookmark the other one and try it some other time.
thanks for the recipe and the response.

Jessica | August 22, 2012 at 10:20 PM

I made a batch of this today just before supper and I could barely eat my supper because I kept sneaking back into the kitchen to eat another bite of this!!! I can't wait for breakfast. The only thing I did differently was add some cinnamon to the mixture before baking. Love it! Thanks for sharing!

cindy | August 23, 2012 at 2:59 AM

OMG, I felt like I was eating a decadent bread pudding for breakfast! I was like "OK, where's the bourbon/caramel sauce?" YUM! I may never eat regular oatmeal again! Thanks, Beth!

...I ended up eating it in a bowl with cold milk (like you), just to remind myself that it was breakfast! :D

cindy | August 23, 2012 at 3:01 AM

haha, your skillet logo needs a slice of bacon underneath, to complete the smiley! :D

Just made this for breakfast. I used pureed frozen bananas, because that's what I had on hand, and I added 1 tsp pumpkin pie spice. Delicious! Looking forward to trying the chocolate banana baked oatmeal next.

WorkingMom FindingFrugal | August 28, 2012 at 9:11 AM

I love your site, and this receipe! The picture looks mouthwatering! I infact have some fresh blueberries and bananas that need to be used up pretty quick. I will be making this tonight and can't wait to eat it in the morning. Thanks!

Manuel Neuer This is very good love it!

Life is beautiful | September 2, 2012 at 1:11 PM

Just baked oatmeal using both the recipes as inspiration...used peaches n blueberries in the bottom,bananas for moisture, no sugar at all and just a pinch of baking powder as I was out of baking soda...baked for almost 50 minutes and it turned out awesome,hubby loved it!!!

JoAnna | September 3, 2012 at 2:45 AM

If I was going to make this to freeze and eat at a later date would I bake it in the oven then freeze it? or could I mix it all up and put it in the freezer until a later time then bake it? doing it either way how long do you think it would hold up in the freezer? and would I bake(or re-bake) it at the same temp and amount of time?

sorry so many questions, I'm just preparing to start doing freezer meals and would like to have this as a breakfast option :)

Beth M | September 3, 2012 at 7:03 AM

JoAnna - I think it's best to bake it, then freeze it in single serving portions. That way, you can just reheat it in the microwave and you don't have to thaw the entire thing. I'm not sure how well it would work if frozen before baking. And remember, always refrigerate before freezing. It's best for the items to be cold before they go into the freezer :)

Kimberly | September 7, 2012 at 9:08 AM

When do you add the milk?

Kimberly | September 7, 2012 at 9:09 AM

Also do you have a FB page and are you really doing a cook book? If so I would LOVE more info about it! kimberlyhorn16@yahoo.com

Beth M | September 7, 2012 at 3:44 PM

Kimberly - The milk is added in Step 2 (or the third photo in the step by step photos). You can find me on Facebook at facebook.com/budgetbytes1 or by clicking the Facebook icon at the top right hand corner of this page. I do have a book in the making, but it's in the very preliminary stages so I don't have any details yet :) But, follow me on Facebook for updates!

Cates | September 15, 2012 at 4:58 AM

I LOVE baked oatmeal! I made a few tweaks to this recipe because I didn't have very many blueberries, but I wanted to make it so badly! Here is what I did and it's amazing!:
1. I left some of the banana chunks in it instead of mashing it completely
2. I added fresh strawberries chopped up to even out the lack of blueberries
3. I used about 2 tablespoons of brown sugar instead of white because I prefer brown with my oatmeal.. but either one I think is good.
4. I saved about ¼ c of oats and I mixed it with about a teaspoon of butter with a tablespoon of brown sugar to sprinkle on top while it was baking
5. I put the mixture in muffin tins instead of an 8x8 inch pan because mine was in use. I liked this because it helped me to not get too carried away with eating it so fast and I froze about half of them so I could take out one at a time when I wanted it again!
I can’t wait to try the chocolate one next!!!!

Jesi | September 29, 2012 at 8:04 AM

Hi! This recipe looks delicious! I just have a quick question -- I'm not too familiar with baked oatmeal, and I was wondering if I could double the recipe and put it in a 9x13 without messing up the baking temp/time? I think it would be thicker in the 9x13 and I don't want to scorch the top to make the middle the right consistency. :-) If you have any tips, I'd really appreciate it! Thank you!

Beth M | September 29, 2012 at 8:39 AM

Jesi - A double batch should work very well in the 9x13 dish. The oatmeal is pretty moist so it would probably take some *severe* over cooking to scorch the top. Keep the same baking temperature and just check on it every 10 minutes or so after cooking for 45 minutes, you'll be okay. It will probably take a little longer to cook than the single batch in an 8x8. It will be done cooking when the top is golden brown and no longer sticky in the center. I hope it turns out well for you!

Jesi | September 30, 2012 at 10:03 AM

Thank you so much! I'm trying to single batch today and if the hubby likes it, I'll let you know how the double turns out. :-)

Leslie | October 4, 2012 at 10:31 AM

Yum! The whole family loved it.

Anonymous | October 21, 2012 at 8:41 AM

This was yummy. I omitted the sugar and used a bit more banana. My 2 year old loves it topped with plain Greek yogurt.

Lauren L | November 10, 2012 at 4:59 PM

Oh, this is yummy! I made it with soy milk and it came out beautifully. I can't wait to have it for breakfast this week. I love it's "fluffy" consistency, I wasn't expecting that!

Jesi | November 10, 2012 at 7:08 PM

Just so you know I have now made several double batches in my 9 x 13 metal pan. It turns out perfectly after about 60 minutes of baking. :-) Thank you for sharing this recipe! I just started my student teaching, and it's SO great to be able to make a big pan of baked oatmeal on Sunday and know that my husband and I are set for a filling breakfast for the whole week -- without getting up earlier to make something. And it's a great bonus that it's inexpensive, since we are poor college students. ;-) Thank you!!

Anonymous | November 12, 2012 at 12:14 AM

Is it possible to use the Quaker quick cooking oats? They are all I have at the moment and I don't want to buy more when I already have some. Thanks!

Beth M | November 12, 2012 at 5:32 AM

Anonymous - You could use quick cooking oats, although the texture will be a lot more mushy.

Anonymous | December 8, 2012 at 8:54 AM

i never liked oatmeal until i tried this.... i've eaten it for breakfast the past 2 weeks! thanks for an alternative to eggs, my usual go-to! :)

Anonymous | January 5, 2013 at 9:30 AM

I have to say, I usually HATE oatmeal but this is freaking DELICIOUS! Thank you!

Kendra | January 6, 2013 at 8:13 PM

I just baked this and it tasted great! However, I have a question about the blueberries. I wasn't sure if keeping them frozen until I added them meant adding frozen blueberries or unfreezing them before adding them. I just added the frozen blueberries straight to the mix, which turned out fine.

I also substituted regular milk with goat milk, which worked too. :)

Beth M | January 6, 2013 at 8:18 PM

Kendra - Yep, you did it right :) If the blueberries thaw out before you add them, the juice starts to run and will turn everything a purple/grey color.

Kendra | January 10, 2013 at 5:01 PM

Good to know! Thanks.

Anonymous | January 16, 2013 at 5:18 PM

I have a batch baking right now as the temps in Minneapolis plunge. As usual, I've subbed in coconut milk and added shredded coconut. Turns out great! And thanks for your eggnog oatmeal tweet-it turned out good as well.

Amanda McGuirt | January 20, 2013 at 8:42 AM

I just made this using a 9x13 since I don't have an 8x8, and I doubled everything (except the bananas, just because I didn't buy enough) and cooked it @ 375 for 55 minutes and it turned out fantastic!

Amanda McGuirt | January 24, 2013 at 12:03 PM

Oh wow - I brought this to share with my office this morning; I have never received so many compliments before! Everyone was asking for the recipe so of course I told them about your fantastic site. Thanks bunches; I just received some seriously good attention from management!

Karen | February 10, 2013 at 8:44 PM

I have this in the oven right now. If it tastes as good as it smells I'm going to be very pleased.

Anonymous | March 18, 2013 at 1:08 AM

Oops - was in a rush when making this and didn't read the instructions thoroughly. I just baked for 45 minutes. The top was nice and golden but didn't check the middle to see if it was wet or not. Then when it cooled, I just stuck it in the fridge for the next morning. Do you think I baked it long enough?

Beth M | March 18, 2013 at 5:52 AM

Anon - It's probably good :)

Stephanie101 | March 18, 2013 at 7:02 AM

I just made this! Oh my goodness, SO delicious!

Anonymous | April 4, 2013 at 8:15 AM

i love love looove your website! i made quite a few recipes and they all turned out pretty amazing (and i save a few pennies)! quick question about this specific oatmeal (which i made yesterday) recipe : could i replace bananas with apple sauce maybe ? thanks beth, you are amazing :) –from gen

Beth M | April 4, 2013 at 1:45 PM

Anonymous - I find that any type of pureed fruit or vegetable works well. Apple sauce is a little less thick than banana, but I've used it in other baked oatmeal recipes with success :)
