Made it for breakfast. Yum yum yum!
Couldn’t wait to make this after seeing it in your stories last week! Imagine my delight when it appeared in my inbox a day early! I made it first thing this morning and it is a smash hit. The house smelled amazing and holy moly the taste: it’s a healthy blueberry crisp. Definitely packing it for my husband for work…and definitely having some with vanilla ice cream for dessert tonight. Thank you for sharing all of these amazing, healthy treats!
Super simple and delish!!
I am so glad you enjoyed it! I agree, I love how simple this is to make and it’s always a hit!
So good. I used summer squash in place of zucchini because it’s what I had and it worked great.
Yay! I’m glad you enjoyed! I have a batch in the oven as we speak because my family is HOOKED on it. I sense there will be more veggie-loaded baked oatmeal recipes coming to TNN.
Saw the recipe this morning and made it right away! Subbed carrots for zucchini since that’s what I had and the kids gobbled it up. So so delicious and the smell while it’s baking is divine!
I love the smell of it baking too! And the carrots make a great sub, which I love for when zucchinis are not in season. So glad it was a hit!
Absolutely delicious! My kids devoured their first helping and asked for a second – a sure sign that this will become part of our regular rotation. The Natural Nurturer does it again! 🙌🏻🙌🏻🙌🏻
Yay! I am so glad! I love when kids love a veggie-loaded recipe!
Perfect fingerfood for my LO! I used mashed banana instead of maple syrup and my 11mo devoured it!! Such a great alternative to porridge or overnight oats and full of all the good stuff 😍
Love that change!
I baked this up this morning for my son and he really enjoyed it!
I didn’t have zucchini so I left that out and used a few drops of Stevia in place of the sweetener called for
I put a little PB on top when I served it to him
Will definitely make again
Love the little changes! So glad you enjoyed it!
What can you substitute the coconut oil for if you don’t have any on hand??
You can use whatever oil you love to bake with. I’ve used avocado oil and I’ve had a few readers use melted butter instead.
My 18 month old loved this and my 5 year old asked if she could have it for dessert! So yummy!
I LOVE this so much! And top it with some whipped cream and it’s totally a dessert!
Made this this morning and it is super yummy and filling! I was worried that the frozen blueberries would be too much moisture, but they weren’t. I did squeeze out the zucchini a bit. Thanks! 😻
I’m so glad you enjoyed it! I made a batch with frozen blueberries this past weekend and it always comes out great! But I think if you prefer a denser baked oatmeal, squeezing out the zucchini is the way to go!
I made this with full fat coconut milk and followed the recipe exactly. Creamy and delicious and my kids didn’t notice the zucchini.
Love that coconut milk suggestion! I bet the flavor was amazing!
Absolutely Delicious! I added a tablespoon each of ground flax and chia seeds for extra nutrients and used half honey and half truvia natural sweetener. Sooo yummy!
Do you think you could double the recipe and use a 9×13 pan? I have loads of zucchini from the garden to use up. Thank you!
Thank you! I made it with rasberries because that is what I had on hand and it turned out good! 6hinking about using some chopped up frozen cranberries next since they need used up!
I made this with carrots (all I had) and wild blueberries I picked. It is absolutely delicious! I write this as I polish off my second piece.
I really hate mushy texture oatmeal but the texture of this is just perfect! Thank you!
I am so glad you liked it, Katie!
Would I be able to freeze this and serve later? I make 2-3 recipes every couple of weeks and rotate daily what I serve my little one because I freeze the waffles and pancakes and then throw them in the toaster.
Absolutely loved this recipe! I substituted date paste for the maple syrup and added some ground flaxseed for extra fiber etc. It turned out wonderful! Even my 3 year old ate it!
Yum! I love those additions, Allison! So glad you enjoyed it!
Do you think this would work with old
Fashioned whole grain oats instead of rolled oats?
Yes! I think they would work well as a swap!
One more question – do you think I could add Brewer’s yeast to make this a breastfeeding mom’s snack?
Hmmmm. Probably! I haven’t tried and truthfully haven’t baked with Brewer’s yeast in so long that I can’t recall how it changes the flavor of dishes. However, if you have and feel comfortable navigating ratios, go for it! I think it would create for a similar recipe in texture and bake
This was delicious! We used carrots because we always have carrots and used flax eggs because we’re out of eggs. All worked great! My three year old probably ate half of the entire dish (like of the whole baked oatmeal tray) by himself for breakfast! Definitely will be making regularly!
So glad to hear that this was a success, Amanda. We make those swaps often too and they always work great!
Love this recipe!! I usually make a double batch in a 9×13 pan, use half the sweetener, and use flax eggs. It’s so good for breakfast or a snack!! I find when I make it in the 9×13 pan I need a little extra moisture so I put in some extra zucchini.
So glad you enjoyed it, Carissa!
Can you bake these as muffins? Thanks!
Oh great question, Abbi! I haven’t tried but I bet you you could. Maybe for 20 minutes…..? If you try it, let me know how it goes!
Loved this recipe! I was out of coconut oil so I substituted avocado oil. I hope that was okay but I love the recipe! And I would recommend parchment paper to line the 8×8 also.
Totally okay! I swap those out often. So glad you enjoyed!
You are seriously a genius. This is so good. Turned out perfectly.
Yay! I am so glad! I love this recipe so and am dazzled that others enjoy it just as much.
These are amazing! I used flax eggs and that turned out really well! This is definitely a new favorite me me and my husband.
I’m so glad you enjoyed, Alana!
I’m about to make this recipe for the fourth time this summer! I absolutely love it. I make it in muffin form for easy portions and add chia and hemp seeds. It checks all the boxes for me – fruit, veggie, protein, fiber, lower sugar. I even made it for a friend with a new baby and it was a hit for her family too. Thanks for sharing this recipe! I just printed a bunch more from your website and can’t wait to try them.
I LOVE everything about this and I am so glad you enjoyed the recipe! I was just telling a pregnant friend about freezing baked oatmeal in portions for a quick reheat-and-eat meal. Adore the idea of doing it in muffin form!
Made this recipe this morning using a multigrain oatmeal that I had that contained buckwheat and flaxseed. Subbed the zucchini with carrots. Delightful indeed!! House smells great and love that I can eat it later this week as I head out early to teach swimming!! Thanks for another great recipe!!
So glad you enjoyed!
Made this bake for breakfast today – followed the recipe exactly as written and wouldn’t change a thing, delicious! My 4 year old agrees 🙂 We will add this to our regular rotation, thank you!!
I am so happy to hear that, Rachel!
Great way to get veggies in at breakfast.
Thank you for sharing this recipe Taesha! I cat wait to make this especially with the warmer days slowly approaching.
I was wondering if you had any idea what adjustments I should make if I were to add four scoops of protein powder? Should increase the amount of milk to two cups instead of?
I’ll also most likely add a drizzle of tahini before eating.
I’m actually planning on baking this today. It just tastes like warmer weather!
Hmmmm. Okay, so I haven’t tried adding protein powder and I think a lot of it depends on how big your scoop is. I know that can vary a lot depending on the protein powder. I’d start with 1 1/2 cups of milk total.
Yup, this is a keeper! I had only made an oatmeal bake similar to this once before. It used bananas and the texture was very gluey, so I was a bit hesitant to try this one but decided to give it a go since I had all ingredients on hand. I was really nervous when I poured the mixture into the baking pan since it was so liquidy, but it baked beautifully and smelled so good. My 15 month old enjoyed it so much for his snack that I had to give him a second piece! Easy, healthy AND yummy – thank you!
I am so glad to hear that, Gina!
Realized I accidentally bought one minute oats instead of regular flat oats. Trying to find ways to use them up. Would this still work?
I tried the one minute in an overnight oats prep but they lost too much texture. Thinking baking might be a better option?
Maybe? I haven’t tried but it might become cake-like, which might be nice! If you try, please share how it goes!
Can’t wait to include this on my plant-based diet. Question … what can be used in place of honey/sugar? I am border line diabetic.
Do you have something else you like to use in baked goods that works well for you? Like monkfruit?
I cannot gave any oil/butter.
Can the oil in this recipe be omitted??🤞
For some reason I thought this would come out like oatmeal bars.
Is it suppose to stay mushy like oatmeal?
While it does firm up as it cools and should be able to be sliced and scooped, it is not like a grab-and-go bar. Many people have had that hope, so I just developed an oatmeal bar recipe and plan to add more. Here is the link…
It’s yummy but 3/4 cup of maple syrup is a lot of sugar! Next time I will use monk fruit
It is 1/3 of a cup…
We’ve used another recipe for years that was more like an oatmeal cookie bar. I loved that this recipe used more fruit and less sugar, fresh fruit instead of dried, and zucchini with a little oil instead of a stick of butter. I also liked the addition of nutmeg, where my usually recipe only called for cinnamon.
We pick our zucchini small, but I like to have recipes that make use of the ones that hide until they’re too big to miss. This was popular enough to make again, perhaps as soon as next week for my parents.
I did 1.5x the recipe in a 9×13, and the only disappointing thing about it was not eating it right out of the oven. But the kids like it cooler and ate all of theirs, so it must have been good.
I am so glad, B! Thanks for taking the time to share your experience!
Is there a way to “fix” this if I didn’t bake it long enough? Thanks.
You could toss it back into the oven for another 5-10 minutes.
So amazing and easy. The kid loved it and so did I. Taking it to the office next week!
I am so glad! Thanks for taking the time to leave a review, Erika!
Made this today (followed the recipe) and it was excellent. Will definitely make it again.
I’m so glad you enjoyed it, B!
Do u drain the zucchini first? Thanks
Great question, because I know in most baking recipes that call for zucchini, you do drain in. But it is not needed in this one! Just toss it in.
Our new family favorite make ahead breakfast! My 3 and 1 year old cannot get enough of it, and I always leave out the maple syrup!
I am so glad, Melanie! I often skip the maple syrup too since my family enjoys it without! I love how the recipe is so adaptable to fit everyone’s unique taste preferences. Thanks for taking the time to leave a review!
Is it really the same cook time and pan size for a doubled recipe? Amazing if so
Great question. The setting on my recipe card doesn’t allow me to change pan sizes or cooking time when someone doubles a recipe. Just ingredients. A good note to put at the bottom.
I think many times, people who bake a doubled recipe like this in two separate 8×8 pans that would, yes, take the same baking time. If you want to cook it in a larger pan, the cook time would depend on your pan size, but my guess would likely need to cook for close to an hour or until golden brown on top.
Made this today. Always trying to get more veggies into my toddler! Great flavor; I think maybe I needed to leave it it a bit longer? The top was definitely done but the inside was pretty mushy. Still tasted good, but probably needed a bit more time. Definitely going to try again with different berries or maybe a combo.
I’m glad you enjoyed it, Jessica! It firms up as it cools, but it is also possible it could also need a bit ore time in the oven. All ovens are a little different and many need to be recalibrated to ensure they are cooking at the proper temp. I know I need to keep an internal oven thermometer (less than $10 on Amazon) in my oven to ensure it is baking at the proper temp. It is possible that your oven is cooking at a higher temp than you think and cooked the outside of the oatmeal a bit faster than the inside.
Thanks for the suggestions Taeaha! The oven is only a couple months old so hopefully it’s working as it should! However, it’s definitely worth grabbing a new oven thermometer just to be sure. I’m pretty horrible at baking so it’s more likely user error! I saw one of your muffin recipes that I’m going to try next and a dinner recipe as well – thanks for all the healthy ideas 🙂
I was wondering when you say “prep the night before” if you mean prep it all the way to baking, but don’t bake, but place wet mixture (in pan) in the fridge, then in the morning take out and bake then(overnight oats style)?…..Or, if you mean, bake it through completion the night before and then reheat it/warm up in the morning? And if you mean the former and keep wet/raw til the morning bake,…bc its basically soaking all night, verses baking it right after you’ve mixed it, would it change the texture and consistency?
You could do either. Prep everything in the pan and put into the fridge to bake in the morning. I haven’t found it change the texture, but I have only done this once before.
What I typically do do prep and bake the night before to reheat and eat quickly in the morning. I find it easier.
This recipe was quick and easy to make…and delicious! Our 2 year old loved it. It was the perfect level of sweetness. We didn’t have nutmeg on hand, so I left it out.
So glad you enjoyed it, Teresa!
I made this a week or two ago and it was wonderful. Love it! I’m so glad to have a baked oatmeal recipe with veggies and fruit – and way less fat and sugar. (And it tastes great!)
However, I have question. What happened to the blueberry flavor in the portions I froze? I heated some in the microwave this morning and it was good, but the blueberries had no taste at all. (They did when it was fresh.) I don’t know if it was the chemistry between the ingredients or the blueberries I had (48 oz bag of frozen blueberries from Walmart) or what. Any ideas? I know I’m not the only one who’s frozen leftovers!
Oh interesting! I’ve never run into that! Hmmmmm. I might have to do some research.
I made this for my 4 & 7 year olds this morning with flax eggs and they ate 2/3 of the pan!
Now THAT is a win! I’m so glad, Errign!
