Stir together this wholesome Blueberry Baked Oatmeal before bed, pop it into the oven when you wake up, and you can sit down to a hearty bowl of oatmeal with the family without any standing by the stove and stirring. Plus: It reheats so well!
This breakfast recipe is easy and delicious, and it’s a nice way to change up how you usually serve oatmeal. It somehow feels more decadent baked in a pan like this—and it’s a great hands-off method to cook oatmeal if you can’t be near the stove to stir.
This is one of my favorite baked oatmeal recipes because it tastes so rich and comforting, but it’s full of whole grains—and fiber and fruit. It’s perfect on busy weekdays (especially if the kids wake you up early!) and you can make it ahead of time and simply warm it up as needed.

Ingredients You Need
Here’s a look at what you need to have on hand to make this blueberry baked oatmeal recipe so you know what to pick up at the store or grab from the pantry.
- Coconut oil: Since this recipe has coconut in it, I use coconut oil to play up that flavor.
- Eggs: Large eggs help the oatmeal hold together as it bakes in the oven.
- Canned coconut cream: This is mainly the solids of full-fat coconut milk and is usually sold in the same section as regular canned coconut milk. If you can’t find this, any type of canned coconut milk can be used.
- Honey: Honey or maple syrup is added to sweeten the mixture.
- Vanilla extract: I add vanilla to the oatmeal mixture to enhance the flavors, and it works really nicely with the berries.
- Steel-cut oats: I love using steel-cut oats here for their nutty and chewy texture. Soaking them overnight helps soften them so they bake up with a soft texture.
- Shredded unsweetened coconut: I love the flavor of coconut, so we add shredded coconut here for coconut flavor.
- Blueberries: We add fresh or frozen blueberries to this baked oatmeal. They bake the same, so you can use either one you like.
Ingredients Swaps
If you aren’t a coconut fan, use butter instead of the oil, regular milk in place of the coconut milk, and additional oats in place of the shredded coconut.
Use rolled oats in place of the steel cut oats, but see the Notes at the end of the recipe for specifics.

My family loves this recipe. Thank you for sharing it, it’s such a time saver too.
I am so glad!
I haven’t tried this recipe yet but was wondering if I can substitute other fruit instead of blueberries I am sure right? Has anyone every tried mango instead of blueberries? My family likes mangos. lol
Sure, that’s fine!
My kids loveddd this recipe. They couldn’t get enough servings. I had to cook it about 15 minutes longer than the recipe said for it to set in the middle.
Note: This recipe is great if you are potty training! Coconut helps loosen things up naturally so it’s easier to go to the bathroom, and this recipe has a lot of it.
Soo good. Will be making this again. I followed the recipe without substitutions, but it never got “firm” in the middle. Just turned to oatmeal consistency. Consistency was still good but maybe should reword that part of the recipe? I even cooked it an extra 15-20 mins.
Thanks for the yummy recipe 😋
I have made a lot of different types of overnight oats and thought I’d try a new recipe. I used the steel cut oats but thought the recipe called for way too much liquid but stuck to the recipe still. I ended up baking it for 45 mins and it is still very liquidy but smells amazing!
The liquid amount would be different for steel cut oats since they cook at a different rate. I hope it turned out okay!
I felt like I needed to bake mine about 15-20 additional minutes because it was still so jiggly and the directions say until set in the middle. Are you supposed to take it out about 35 minutes when it’s still jiggly or is it just me and my oven is off? I did sub almond milk for coconut milk.
Super excited about this recipe though. It was tasty and my 14 months old who isn’t wild about breakfast ate a portion. Love something I can prep the night before and just put in the oven the next morning.
It’s possible that it took longer since almond milk is typically much thinner in consistency than coconut milk. I would look at the center to be set. And I’m glad you enjoyed it!
Thank you so much for sharing this.I didn’t have chia seeds so used an egg. It still came out yummy. Most importantly my fussy eater toddler ate it 😊
Sooo good! Both my toddler and my husband love it. I’ve made it three times already!
My daughter always asks for this so you know its good. Make it w regular oats and add some cinnamon. SO good.
I cooked this for 40 minutes and it was still soupy but set a bit more after I let it sit for 10 minutes. My husband and o loved it. Our toddler decided she doesn’t like coconut so she wouldn’t eat it though – who knows?! I’ll be eating the leftovers!!
Followed the recipe and the steel cut oats were not cooked well…some crunchy bits remained so my toddler wasn’t happy. It was left for around 7h overnight. Should that have been long enough?
It should have been long enough. I haven’t ever had that happen, but I am sorry you did!
Hi! I am really enjoying your recipes! If I make this with regular oats, can I just mix and bake in the same morning (instead of letting it sit overnight)? Thank you!
Hi-I think you can do it with regular oats, but I suspect you’d need much less liquid. I have done it with rolled oats as the recipe is written (soaking overnight) and used 1.5 cup rolled oats. To make it without soaking and with rolled oats, I am guessing—I think you’d maybe want to eliminate the water all together or use just 1/4 cup.
Thanks so much! It turned out great – I used 6 oz of coconut milk without any water and 1.5 c old fashioned oats. It was done in 35 minutes. I would definitely make this one again!
Hello! I would like to make this but do not care for coconut. Do you think I can I just use 5 oz regular milk instead and omit the other coconut?
Absolutely!
