I love this baked oatmeal because it’s simple, comforting, and a great way to start the day.
I layer fruit in a small baking dish, top it with oats and a warm blend of milk, butter, vanilla, egg, and honey, then bake it until golden. It feels like something special, even though it’s so easy to make. Whether you top it with yogurt or enjoy it just as it is, it’s one of those recipes I turn to again and again.

Ingredients
If you have any ingredients leftover from this small batch baked oatmeal recipe, check out our Leftover Ingredients Recipe Finder.
- Oats: Use old-fashioned oats for the best texture. Leftover oats can be used in recipes like small batch oatmeal raisin cookies, a single strawberry crisp, blackberry crisp for one, or small batch gingerbread granola.
- Cinnamon and Salt: Cinnamon adds warmth; salt enhances the flavor. Try nutmeg or allspice for a variation.
- Milk: Use any milk you like, dairy or plant-based (such as almond, soy, or coconut).
- Butter: I use salted butter for added flavor.
- Vanilla Extract: Adds subtle sweetness and enhances the flavor.
- Egg: Helps bind the ingredients.
- Honey: Lightly sweetens the oatmeal. Adjust to taste or use maple syrup if preferred.
- Fruit: Blueberries are a great choice, but any fresh or thawed frozen fruit works well.
Recipe Variations
Try one of these easy variations to change up the flavor of your baked oatmeal:
- Tropical: Use coconut milk and add pineapple chunks and shredded coconut.
- Apple Cinnamon Raisin: Stir in grated apple, raisins, and an extra pinch of cinnamon.
- Mocha: Add 1 teaspoon instant coffee and chocolate chips for a mocha flavor.
- Savory: Leave out the fruit and sweeteners. Add chopped spinach, crumbled feta, and black pepper.
- Pumpkin Spice: Replace some of the milk with pumpkin purée and add pumpkin spice.

Can this recipe be assembled the night before? Or do you have a make ahead one recipe? I would like to have a baked oatmeal that can be put into oven in am right away.
Hi Connie, you can prep the dry ingredients and separately mix together the egg, milk, and vanilla. In the morning combine the ingredients and bake.
Please note that the way you write your receipe, many pages with pictures, does not make it possible to print just a one page receipe. If you could separate the receipe out so it is printable would be nice. Many of us don’t need step by step instructions nor pictures.
Hi Dianne, you can simply jump down to the recipe using the “Jump To Recipe” button on the top of every recipe page.

Heavenly! Just made a few tweaks for my dietary and taste needs. Used sugar free maple syrup instead of honey and did add a little more sugar substitute for sweetness. Definitely a keeper♡
I have made this many times! Delicious! I also added peaches with the blueberries.
Have you tried this with egg replacer instead of the egg and did it work?
No, this recipe has not been tested with an egg replacer.
Can you use steel cut oats? Would it alter the cooking time? Thanks
No, Steel cut oats are the texture of a grain like rice or barley, so they require much more cooking than rolled oats.
Can egg whites be used instead of the whole egg?
Yes. Use 2 egg whites in place of 1 whole egg.
Delicious! I also added sliced bananas. I would make this again!
do you think it would be okay to omit the egg? or will it drastically change the consistency?
I don’t recommend leaving out the egg. The egg makes the oatmeal more like a custard and the texture would be very off if left out.
So easy and delicious. Used mixed berries and pure maple syrup instead of honey.
This recipe popped up in my mail today and I had to make it right away. This will now be a go-to breakfast for me. So delicious! I added some chopped pecans to the dry ingredients and used a tablespoon of real maple syrup for the perfect amount of sweetness. Thank you for sharing!
Love this recipe! I actually doubled it so I would have more than one serving. Love the fact that there is no flour in the receipt. It is delicious!
This was so GOOD ! Will be making this again for sure…
Cathie
I made this for breakfast today! Apples and cinnamon with maple syrup. Was really wonderful and easy. Love the fact that I can rest between prep and eating, gives me time to recover!
So easy to make! I prep everything the night before (as I am preparing my lunch) and the next morning, I add the egg, milk, and vanilla and bake. Once it is finished, I have showered and gotten ready for a day in the office, time to sit down and enjoy a piping hot breakfast. Thanks!
If using frozen blueberries do they need to be thawed? Also if using different fruit is it still 1/4 cup?
Yes, the fruit should be thawed. You really want to have enough fruit to loosely line the bottom of the baking dish. Somewhere between 1/4 to 1/2 cup of fruit works well.
Can this recipe be doubled or tripled to have leftovers? Does this recipe reheat well for breakfast for a couple days?
Hi Dina, This recipe can be doubled and tripled successfully. Although it’s best enjoyed the day you bake it, baked oatmeal can be reheated in the microwave. I like to add a little bit of butter to the top of mine when reheating. The butter melts into the oatmeal and moistens it nicely.
I put this together the night before then baked it in the morning added a spoonful of yogurt and yumm!!! I did add more than 1/4 cup of berries and used blueberries, raspberries and blackberries. So good! Will definitely make this again and again! I still baked it for 40 minutes and it was perfectly cooked and golden brown.
I’m so glad you enjoyed it! Thank you so much for your feedback.
Making it again this morning! Delish.
Can I substitute a flax egg in this to keep it vegan? It sounds delicious!
Hi Susan, I haven’t tested this recipe using a flax egg so I’m not sure how it will work. If you try it, please let me know how it turns out for you.
Used thawed rhubarb added a little brown sugar and followed recipe it was excellent
If using frozen fruit, should you thaw it first?
Yes.
Can this recipe be made the night before to pop it in the oven in the morning? What would be the baking time?
No, I don’t recommend it. The oats will absorb the liquid making it the consistency of “overnight oats”. You could mix together the liquid ingredients a day ahead, refrigerate it and pour it over the oats in the morning before baking.
Does this reheat well? I’d love to be able to make it ahead of time for my husband…
It’s best eaten shortly after it’s come out of the oven but it does reheat well in the microwave.
Could you cook this in an Instapot?
This recipe has not been tested in an Instant Pot.
I’ve made this blueberry baked oatmeal several times, and it is so yummy. It’s nice to have a warm and comforting breakfast for cold fall/winter mornings. I’ve also developed some variations of the recipe. My best so far is pumpkins-chocolate chip!
I make my own oatmeal packets. With your ratio plus egg I could use those as my dry ingredients. Love the idea of multitasking oatmeal. Thanks so much for all your recipes and tips.
Can this be cooked in an Air Fryer?
I haven’t tested this recipe in an air fryer.
This is now officially my favorite way to have oatmeal in the morning! I have experimented with different fruits – peach is really good, but blueberries have to be my favorite way to enjoy this. I also like to add a handful of chopped pecans for a little extra crunch. Thanks for another great recipe!
This is simply amazing! I used slightly more than 1/4 cup blueberries, just filled the bottom of my 4 x 6 baking dish. I used almond milk (regular) for the milk so I cut the sweetener to 1/2 T. maple syrup (can’t digest honey). Served with Oui coconut yogurt alternative, vanilla flavor and I gobbled it up, would have licked the bowl if I could. Thanks for another outstanding breakfast recipe. I have made your pancakes and waffles for one and now this. Going to start branching out to other meals next. Thanks for all you do!
I’m so happy you enjoyed the oatmeal. Thank you so much for your feedback.
I just made this for breakfast…..I cant even convey how FREAKING GOOD this was! I substituted the honey for maple syrup (not a honey fan) and I added 1/8 tsp of Equal to the dry mix…(I love things a bit sweet). Used fresh blueberries, and few slices of Banana…..My heart is singing, my stomach is smiling, and I cant thank you enough! This is a keeper…
I’m so happy you enjoyed the oatmeal. Thank you so much for your feedback.
What size dish do you use
A 5×5 inch baking dish.
FYI for anyone panicking, I actually mixed it all together instead of layering because oops and it turned out great still.
Just put this in the oven. Really excited!
pretty good, used maple syrup instead of honey, would recommend adding more cinnamon.
Turns out great. I use the 1/3 cup measures instead of 1/4 cup to make enough for 2 servings.
I’m so glad you are enjoying the recipe. Thank you for your feedback.
Yummmmm! I made this for breakfast today. Does it work well if you prepare it the night before and just pop it in the oven in the morning? Thank you for a lovely breakfast!
I just made this. It’s delicious!
When do you put the honey in?
Add the honey in Step 3 of the recipe where you mix the milk, butter, vanilla, egg, and honey together.
Step 3: In another small bowl, whisk together the milk, ½ tablespoon melted butter, vanilla, and egg.
Believe this step should also include the honey?
Yes, add the honey in Step 3.
Joanie,
You are incredible and so is this breakfast! Thank you so much!
You are too kind, Sherrie. I’m so happy to hear you enjoyed it!
Anther great recipe. I’m was wondering is the another similar pan you can use.
Thank you, Mary. You can use any oven-safe baking dish that will hold the ingredients and still leave a little room at the top.
Could you use steel cut oats?
Also how do you reheat in the oven?
Thanks
If you want to reheat the oatmeal in the oven, I would recommend covering the dish with a sheet of aluminum foil to keep the oatmeal from drying and heating it at 350 degrees. Since you just want to heat it, the oatmeal should not take very long, maybe 8-10 minutes. Or you could reheat it in the microwave.
I’m actually not sure. This recipe hasn’t been tested with steel cut oats.
If a toaster oven is used, would the baking instructions be the same?
Yes, it should stay the same.
Does the milk particularly need to be one percent? Just wondering. Looking forward to trying this recipe soon.
Hi Ben,
No, I listed 1% because that’s what I often use. Feel free to use whole milk, 2%, almond, soy, oat or coconut milk instead.
This is the best thing I’ve ever eaten. I’ve made it twice now and I love it. Didn’t have honey on hand so I used brown sugar. I do one thing differently, when I heading the oven, I put my buttered 5″ round pan in the oven with fruit covered with a bit of brown sugar and once everything else is prepared, I finish per instructions. I do have a question, do you have a baked oatmeal recipe without fruit?
Hi Andrea,
I’m so glad you enjoyed the recipe. You can leave the fruit out of this recipe if you’d like – it’ll still be delicious.
Joanie
Can this be prepared the night before and cooked in the morning?
Yes it can be prepared overnight and baked in the morning.
Enjoy!
This sounds wonderful! But I don’t have that much time in the mornings. Would it work okay to bake the night before and reheat in the morning? Or would that ruin the texture? Thank you!
Yes, you can bake the oatmeal the night before and reheat in the morning.
This is the perfect serving size for one person!! I really enjoyed this. The second time I made it I broiled it on low for a minute or two just to get the top extra brown and crispy, and it was even more delicious 🙂
I’m so happy you enjoyed the recipe. Thanks so much for your feedback.
Having a lot of fresh cranberries from the holidays I substituted them for the blueberries. It was fantastic and gave the dish a whole new tadte.
FOR JENNIFER: TO PRINT THE RECIPE(S) NEEDED, DO A ‘CUT AND PASTE’ OF THE PARTS WANTED ONTO A ‘NOTEPAD’ PAGE MAKING ANY CHANGES WANTED OR NEEDED — THEN DO A ‘PRINT’…SAVES PAPER AND ONLY TAKES A MINUTE OR TWO…
Hi, is there any way to print your recipe without the pictures? 7 pieces of paper instead of 1. Looks delish and hope to try it soon. thanks, Jen
Hi Jen,
I have the pictures in the recipe so the instructions are clear. I do not know of a way to print without the pictures.
