This is delicious! Used frozen blueberries, zucchini and honey. Will definitely make this again. Thanks for sharing.
So glad you enjoyed, Carrie! I just made this today with frozen blueberries too. Such a great way to be easily enjoy this year round!
This sounds delish! Planning on making with frozen berries today. Do I need to defrost them first or just mix them in frozen? Thanks!
I usually just mix them in frozen. Heads up, they will make your oatmeal purple, but just as tasty!
This recipe is amazing! I made it with almond milk and added chia and collagen. Turned out perfect. I travel a lot for work, so this is a perfect meal prep for my travels. I will absolutely make this again. Thank you!
I’m so glad you enjoy it so much, Kelsey! I love to make this recipe for meal prep too. It keeps so well and is so filling! Thanks for taking the time to leave a review!
I love the idea of using Almond milk! How much Chia did you add?
Do you think using 2 cups of small blueberries would be too much and make it too soggy? I’m trying to use up my berries. I have plenty of zucchini also though so maybe I just need to make multiple batches and freeze them!
I think it would be okay!
Has anyone tried freezing servings for future use? Would love to make this for meal prepping. Would love any insight on freezing.
Delicious and nutritious recipe for me and my two girls. Can it be frozen? 🙂
Yes!
How big is the serving size??
1/8 of the batch. Once cooked, I cut the baked oatmeal into 8 pieces and one of those is a serving.
Thank you! My pan was actually 9×9 so I divided into 9 squares. It was sooo good.
I’m so glad you enjoyed it!
Really really tasty! Was so good accompanied by some almond butter and a cup of coffee ☕. As always love the subtle sweetness of your recipes. Don’t wanna feel like I’m having dessert for breakfast. Don’t get me wrong, I love me some sweet indulgent desserts, but for dessert you know. : )
Totally feel the same way, Eva. I love the slightly sweet but not sugary breakfast goods, too!
This was a winner! My kids loved this. I did strawberries instead of blueberries because it’s what I had on hand and it was so good. Super easy. It will definitely go in the rotation.
Oh I bet this was amazing with the strawberries!
Could this be made ahead and frozen in individual portions?
Yes! I’ve done that several times and it works great.
This recipe looks and sounds delicious! I’ll be making it in the next couple of days. But I hate heating up the kitchen with the oven in this triple-digit heat we’ve been having. How would it do in a toaster oven? I haven’t tried baking in it yet, but it makes great dinners! Any adjustments recommended on time & temp in a toaster oven? I’ll be using an 8”x8” glass baking pan. Thanks!
Hi Chris! I totally get not wanting to heat up your kitchen with the big oven. I haven’t tried baking in a toaster oven, so I can’t give you much guidance there, but I feel like the baking times should be the same if the it can reach the proper temp.
can you use quick oats if that’s all you have?
That should work okay!
I’ve made this several times now, and it’s really good! I usually just use frozen mixed berries and sometimes I’ve subbed some of the zucchini for carrots if I didn’t have enough zucchini. I also always double it for a bigger pan and bake about 55 minutes, and it comes out great every time. My kids love it too, and it’s nice to know they’re eating a healthy breakfast and getting some veggies in!
Delighted to hear you enjoy this recipe as much as we do, Sarah! I often swap the zucchini for carrots and frozen berries makes this a breakfast we can make all year long
Love this!! My two year old daughter and I couldn’t get enough of this! Making for the second time now and I doubled it. Great way to use up all that extra garden zucchini, and it tastes delicious. I love knowing it’s so good for us too!
Loved hearing this so much, Sarah! Thanks for taking the time to leave a review!
I want to make this for my 1 year old, could I omit the maple syrup/honey all together or will the taste be very off?
Hi Danielle. It won’t be sweet past the blueberries, but if your little is okay with that then leave it out. You could also replace it with mashed bananas or applesauce for a natural fruit sweetener.
