Warm apples, hearty oatmeal, crunchy pecans.. what’s not to love about this easy baked oatmeal?
Gluten free, delicious, and simple to make – baked oatmeal is hands down one of our absolute favorite breakfast recipes (which is why we have so many versions! Carrot Cake Baked Oatmeal, Chocolate Peanut Butter Baked Oatmeal, Blueberry Baked Oatmeal to name a few!)
Our favorite thing about baked oatmeal is that instead of having to stand by the stove and watch your breakfast, all the oatmeal ingredients get tossed together and baked in the oven for a simple meal!
This is a great recipe to meal prep for the week and have for breakfast or snacks!
Why we love this recipe
This apple baked oatmeal has great texture from the old-fashioned rolled oats, and delicious flavor from the apples and maple syrup.
- Meal prep friendly – Bake once, eat all week for breakfast. Rather than cleaning a sticky pan every morning, you’ll have 2 dishes to wash!
- Portable – Can be eaten on the go or on a dish!
- Tastes great cold or warm – I prefer it warm but it’s totally yummy right out of the fridge.
- Has only 11 ingredients – nothin’ fancy – all pantry staples you probably already have!
- Takes under an hour to make!
Ingredients
To make this Apple Baked Oatmeal you’ll need:
- old fashioned oatmeal
- ground cinnamon, ground ginger, ground nutmeg
- extra virgin olive oil (coconut oil works as well)
- egg
- maple syrup (honey also works well)
- almond milk (oat milk or whole milk if you’re not dairy free)
- apples
- pecans (optional)
Substitutions
Fresh Apples vs Canned Apples: Fresh apples work best in this recipe. We don’t recommend using canned apples. We love gala, fuji, or pink lady apples for this recipe.
Fruit substitutions: Baked oatmeal is pretty flexible and you can make a lot of substitutions to it. You can sub in any type of fruit or berry in this recipe for the apples. I’d check out this Chocolate Peanut Butter Baked Oatmeal or Healthy Blueberry Baked Oatmeal if you’re looking for something a little more decadent!
Maple Syrup: You can sub honey for maple syrup or agave. I have not tried this with stevia so I’m not sure how that would work. I tested this recipe with honey – both were delicious!
Vegan Baked Oatmeal: Sub egg for one flax egg, sub honey for maple syrup, make sure to use a dairy free chocolate chip
Gluten Free: make sure you’re using gluten free certified rolled oats.
Milk: You can use any type of milk in this recipe. Regular dairy/non dairy will work! Try our homemade Walnut Milk or Almond Milk.
Optional add ins: chopped nuts, chocolate, shredded coconut, or more fresh fruit would be delicious.
Steel Cut Oats: You can use steel cut oatmeal in this recipe. Use 1 cup of steel cut oats and 2 cups of liquid/milk. We have a Baked Steel Cut Oatmeal recipe that you can also follow!
Rolled Oats vs Quick Oats-Quick Cook Oats: I have not tried this with quick cook oats and wouldn’t recommend it. I don’t think that it will hold up/cook correctly with the smaller oats.
Baked Oatmeal Cups: I haven’t tried baking these in muffin cups but I think it would work! The only thing I would say is it will be harder to clean up and it might stick to a muffin tin. I would grease the muffin tins or use these silicone muffin liners. You can bake for a little less time.Â
Nuts: A 1/2 cup of chopped pecans or chopped walnuts would be a great addition to this recipe.

How to serve
This Healthy Baked Oatmeal is a complete meal in itself, but you can serve it with your favorite toppings. I like to serve it with greek yogurt. You can also add maple syrup if you’d like. It’s also delicious with Egg Muffins or Egg White Frittata.
Can I Make this in advance?
Yes you can make baked oatmeal in advance! We would recommend baking, cooling and reheating this, rather than letting the oat mixture sit overnight.
This oatmeal bake also reheats really well so feel free to bake it and then just pop it in the microwave or oven when ready to eat.
If you’d like to prep the dry ingredients and the wet ingredients separately for the batter that would work fine, but don’t mix your batter and leave it in the refrigerator overnight as it might absorb all the liquid.
Storage options
Storing: Do not store this healthy baked oatmeal at room temp. It likely will get moldy or stale if you don’t refrigerate it. This baked oatmeal will last in the refrigerator for up to a week.
Freezing baked oatmeal: Bake, slice and freeze your oatmeal. You can wrap this in individual portions to make it easier, allow slices to freeze and then put them in a ziploc bag or airtight container so they don’t stick together. Baked oatmeal will last about 3 months in the freezer.
How to reheat
You can easily reheat apple baked oatmeal! This oatmeal is great when microwaved or warmed in a toaster oven.
Every microwave and toaster oven will be a little bit different but it should be warmed through in under 1 minute in the microwave

Kay says
Really digging this baked oat recipe. I usually eat overnight oats with stewed fruit in the morning, but sometimes it feels like a slog. Bars feel like a treat even though the ingredients are basically the same (plus an egg). It’s just as easy to make ahead and measure out portions.
Liz Marino says
So glad you like them, Kay! thank you!
Sharon says
The best baked oatmeal recipe! Love this and make it often. I freeze the leftovers and pull out as needed. Top with some yougart and honey and it’s perfect!
Tammy says
I love this recipe! Its so easy to throw together with ingredients I have on hand and it tastes great! I serve it with a bit of greek yogurt as suggested. I’ve actually made it three times in the last two weeks because it’s that good.
Gail Hissom says
Just made this for the first time today. OMG! It is so good! The texture is perfect! Will definitely be making this again! 😋
Liz Marino says
So glad you enjoyed it, Gail!
Kristina says
My neighbor brought me some apples from their trees and I immediately whipped this up. So delicious! I omitted the nuts and the in a little extra cinnamon because… cinnamon!
Liz Marino says
Yum! What a great neighbor 🙂 Enjoy!!
delaney says
so good and easy!! just make sure you use a good apple! made it first with gala apples and it was just okay but made another batch using granny smith and it’s amazing! i also used about two cups of apples instead 🙂
Ann M Deal says
When hovering over the serving number, changing from 4 to 6, the nutrition facts per serving remained the same. Am I doing something wrong?
The Clean Eating Couple says
No, the nutrition facts are the same. The nutrition facts are per serving. The recipe as written yields 4 even squares, AKA 4 servings. If you adjust the recipe for 6 servings, cut it into 6 squares and you’ll have the same exact serving size and same nutrition facts!
Ken Blume says
Best healthy baked oatmeal that there is.
I am amazed at how great it came out.
Instead of 2 TBL maple syrup, I used three. I didn’t use ginger or nutmeg.
For left-overs, I found it better cold than microwaved.
The only problem I might have is stopping at one or two pieces.
I tip my chef’s hat to you both!
Robin Caldwell says
THE best! Switched pecans for walnuts and added cranberries! Delish! We are enjoying it all week!
Michelle says
Super easy to make, very healthy and whole ingredients, vegetarian and delicious. I made it the night before and had breakfast for four days. I definitely recommend.
Sarah says
I tried it but it was bland. Was there something I did wrong? I did put a bit of honey on top and got a bit better. It seemed like everyone liked it so I am thinking it is me. It is such a healthy recipe and I like your other recipes. Thank you
The Clean Eating Couple says
Hi Sarah! Just saw your other comment come through, we review all comments before they’re posted which is why it didn’t immediately show up. I wonder if your apples weren’t that sweet? It seems like you just maybe you like your oatmeal sweeter if you liked it with honey on top. I’m not really sure what to say! Sorry you didn’t like it! It shouldn’t have been dry though, this is a very moist recipe. Did you let the batter sit for too long before baking?
Giselle says
This was great! I doubled it for our family of 6 for second breakfast. I subbed monk fruit for the maple syrup for calories’ sake since I am getting a little too hefty these days. I also subbed the almond milk with some watered down cream that was on the verge of souring. I also accidentally cracked a third egg in there but it wasn’t eggy, thankfully.
Somehow we finished the whole thing. There’s no way my kids were that hungry, so the taste must have been what they were after on their third servings. Will definitely make again.
Alivia Segal says
This was so yummy! I added brown sugar, mashed banana, blueberries and some mini chocolate chips. Definitely made it not so healthy but well worth the treat topped with some yogurt! A must have recipe you can play around with!!
Maria says
Delicious! I followed the recipe exactly except for using walnuts instead of pecans. I only had a 9×9 pan available, but it still came out great (just had to reduce the baking time). I love recipes that I can make and then have a quick breakfast to heat up for the following few days.
Scott says
What would be a good way to add more protein with this? I’m thinking of trying this recipe with peanut butter, but any other recommendations are encouraged. I’m really looking forward to tryin this, thank you
The Clean Eating Couple says
I wouldn’t try to add protein into this, I’d pair it with something else that is high in protein lik e or
Jen says
I make it with soy milk to add more protein. If I’m out of soy I’ll add 3/4 cup cup peanuts to 2 cups water to make peanut milk. I often add 1/2 cooked chickpeas to a blender with whatever milk I use. It doesn’t make it taste like beans, but it adds a more complex/richer flavor, plus more protein.
Anne S says
The only reason I didn’t rate this recipe is that I made modifications to fit what I had on hand. I used skim milk and almonds instead of almond milk and pecans. I also added an extra tablespoon of maple syrup because I have a sweet tooth. I’ve made this recipe several times and keep going back to it. I love eating it reheated with fresh berries on top.
The Clean Eating Couple says
glad you liked it! you could still leave a rating 🙂
