Put breakfast on autopilot with this easy baked oatmeal recipe that uses peaches for sweetness and heart-healthy pecans for crunch. This dish is the perfect overnight or make-ahead recipe to feed a crowd for breakfast!
This versatile baked oatmeal recipe is easy to make with only 5 minutes of hands on prep. Plus, you can easily make it vegan and swap in your favorite fruits or nuts to make it your own!
Oatmeal is a healthy breakfast recipe. But in the summer, you might not want to stand over a stove stirring oats. You can opt for overnight oats or granola with yogurt as a great alternative.
However, if you have a hankering for a warm bowl of oats, this baked oatmeal satisfies!
Use your favorite fruit
I use fresh peaches to brighten up the oats for summer. Overripe peaches work very well here and you can feel free to add as much as you need to use up. Chop the overripe fruit and stir it into the mix before baking.
Fresh, frozen or canned peaches work. The recipe is the perfect base. You can enjoy it with canned or frozen peaches all year long or swap in your favorite seasonal fruit such as figs, apples, or pears in the cooler months.
If using canned peaches, be sure to fully drain them before adding to the oat mixture.
Substitutions
- Sugar. Swap pure maple syrup with brown sugar or date sugar in equal parts. White sugar doesn’t provide the same flavor but can work in a pinch. You can omit the sugar altogether but based on my experience, most people prefer some sweetness in the recipe.
- Butter. Swap butter or plant butter in equal amounts. Though you can use oil, the butter adds extra flavor.
- Egg. Eggs are optional but add a little protein. Eggs also help bind the baked oatmeal. For a vegan recipe, omit the egg and opt for a looser texture. Or use a liquid plant egg equivalent or use a flax egg (see recipe below).
- Pecans. These are completely optional but add healthy fats and crunch. You can swap in almonds or if there’s a nut allergy in the house, try toasted sunflower seeds.
How to make a flax egg: Combine 1 tablespoon of flaxseed meal with 2 ½ tablespoons of water. Let sit for 5 minutes to thicken. Add it to your recipe in place of one egg.
Serving ideas
Feed a crowd. This recipe is perfect for making ahead. Pack or buy the ingredients to bake it onsite or take the cooked baked oatmeal with you on a family vacation in the mountains this summer or serve it as a healthy brunch recipe.
Make it for meal prep. Because this recipe will last about 4 days in the refrigerator, you can make it on a Sunday and enjoy a ready-made breakfast throughout the week.
Add some protein. Add a dollop of Greek yogurt to give this breakfast more staying power. The fiber and protein combination will keep you satisfied for hours. You can also add a scoop or two of protein powder. Try pea protein for a vegan option.
And if this recipe has you now craving a peachy dessert, make this Peach Crisp Skillet immediately!

Fresh Peach Baked Oatmeal
Ingredients
- 2 cups old fashioned oats
- ¼ cup chopped pecans
- ¼ cup brown sugar or maple syrup
- 1 teaspoon cinnamon
- ⅛ teaspoon nutmeg
- 1½ cups milk (or non-dairy milk)
- ½ teaspoon vanilla extract
- 1 tablespoon melted butter or vegan butter
- 1 egg (or liquid plant egg)
- cooking spray
- 2 ripe peaches thinly sliced
Instructions
- Preheat the oven to 375 F.
- In a medium bowl, combine the oats, pecans, sugar or maple syrup, cinnamon and nutmeg .
- In a second bowl, whisk together the milk, butter and egg and vanilla extract. Add the wet ingredients to the dry. Stir to combine.
- Spray an 8×8 baking dish with cooking spray. Pour the oatmeal mixture into the prepped dish. Top with fresh peach slices. Bake 20-25 minutes or until the edges are bubbly and slightly browned.
- Serve warm. Top with additional peaches, pecans, brown sugar or maple syrup, if desired. Store leftovers covered in the refrigerator for up to 4 days.
Notes
- Swap equal parts maple syrup or brown sugar to sweeten the oatmeal. You can leave this out but most peaches aren’t sweet enough for most people.
- Use butter or plant butter in equal amounts. Though you can use oil, the butter adds extra flavor.
- Egg is optional but adds some protein and binds the oatmeal well. Omit the egg or use a liquid plant egg equivalent to 1 egg or you can try a flax or chia egg. Combined with plant based butter this will make the recipe vegan.

What a delicious breakfast this is! This would be perfect for a weekend brunch too 🙂
Marisa
Agreed! Perfect, easy dish for brunch!
Tara | Treble in the Kitchen
I’m like you! I love oatmeal for breakfast but I’ve been enjoying ALL the smoothies this summer 🙂 I’m sure I’ll go back to oats when things cool down a bit.
Marisa
Yes. With the hurricane cooling things down here in the south, I’m getting all of the feels for fall.
Deanna Segrave-Daly
I saw this on your InstaStory and glad I got to the recipe. I adore baked oatmeal too but it’s been too long since I’ve made it – this combo sounds lovely!
Marisa
Thanks, Deanna! It’s now in regular rotation. Next week I’m adding figs!
Kaleigh @ Lively Table
My favorite flavors all together in my favorite breakfast! Can’t wait to make this fabulous dish!
Marisa
mine too! Couldn’t resist adding the peaches as the season ends!
Sareta
This looks so tasty! I’ll definitely bookmark and save this to my breakfast lists. Thanks for sharing 🙂
Marisa
Thank you, Sareta. Let me know if you give it a try!
Christine
My daughter came home from a missions trip to Louisiana and wanted the baked oatmeal she had down there. I’ve never made it, so I’m trying your recipe tomorrow morning! Thanks!
Marisa
Awesome! Please let me know what you think! I’m going to make it again this weekend with fresh figs on top!
Inga
I’m so glad I found this recipe! It’s a delicious way to wake up on a cold morning! I put peaches on the bottom and on the top, and I didn’t have pecans so I subbed in sliced almonds. Really wonderful! Thank you!
Marisa
Thanks so much for the note, Inga. Great idea. Almonds would be delicious for sure!
Kathy
Can canned peaches be used?!
Marisa
Yes. Canned peaches work great. Just be sure to drain them well. Hope you enjoy it!
Judy
It doesn’t say how much vanilla to use.
Marisa
Hi Judy. Thanks for the note and pardon the omission. I will update the list.
I’d use 1 teaspoon but the recipe works great with or without the vanilla.
Myrtle
Recipe sounds great will be trying this morning thanks so much.
Mary
Can this be mixed up the night before and bake in the morning?
Marisa
Hi Mary, Yes. This can definitely be prepped the night before and baked in the morning.
Mary
Hello! This oatmeal tastes great and is so easy to make. I just mix it up and refrigerate overnight. Bake in the morning. We really enjoy it. Thank you for sharing the recipe.
Mary
Christina
Delicious! This was so easy to make and almost all ingredients we already had on hand! Love that you can switch it up with seasonal fruit.
Carolyn
This was so good!!! I struggle with breakfast and finally found a way to enjoy oatmeal with this recipe! Thank you!
How big would you say a serving is (in cups, ounces or grams)?
Brandie
I’ve been eyeing this recipe for days now and finally had some time today to try it out and it’s delicious! Perfect for breakfast or a snack, not too sweet and the fruit on top keeps it from being too dry like oatmeal can sometimes be. I used oat milk, nectarines and chopped walnuts since that’s all I had in the pantry. Will definitely be making this regularly.
Katie
I also tried it with plain oat milk because my daughter has a dairy allergy and it is delicious! I am so glad that you posted your comment. I will also be making this often!
Joan
Can I use a flax egg in place of a real egg?
Thanks!
Marisa
You definitely can. Flax or chia eggs work great!
Lane
Has this recipe been tried with steel cut oats?
Melissa
Fabulous! This was a huge hit with my family. I was short an egg, so I mashed a banana up and added it instead. So good! I just bought extra peaches today so o can freeze some to make this recipe year round.
Pat
This sounds perfect for a work breakfast meeting! Thank you! How long would I need to bake if I double recipe and bake in a 9 x 13 pan? Can I use canned fruit?
Marisa Moore
The bake time might increase about 10 minutes if you double the recipe and use the larger baking pan. Check the center to ensure fineness.
And yes definitely to canned peaches but be sure to drain them. Enjoy!!
Katrina
I would love to make this! I have a super hard time getting enough protein in my little guy. How could I incorporate protein powder? Maybe just add some chia seeds? Hmmm
Marisa Moore
1-2 scoops of protein powder should be fine. But I wouldn’t add chia to the mixture without adjusting the liquid up. (I haven’t tested that)
For extra protein, I usually serve this with Greek yogurt.
Courtney
So tasty! Thank you for sharing! If anyone is concerned about the sugar, I used coconut sugar in place of the brown sugar. It’s lower on the glycemic index and gives a fabulous almost caramel flavor that I highly recommend with this delicious recipe.
Shelley Cook
Is it okay to use the 1 minute oats in this recipe or does it have to be the regular oats?
Marisa Moore
You can but the final texture will be different – less hearty. You might also need to decrease the cooking time. I highly recommend regular oats.
