Wake up to the cozy flavors of fall with this comforting baked oatmeal—a warm, make-ahead breakfast that’s perfect for chilly mornings.

Baked oatmeal is a traditional and comforting breakfast casserole. Unlike regular oatmeal, which is made on the stovetop and has a porridge-like consistency, or overnight oats, which are served chilled, baked oatmeal recipe is made in the oven and has a consistency similar to bread pudding. There are endless variations, like blueberry baked oatmeal and morning glory baked oatmeal, but this version with juicy apples, plump raisins, and warm spices is a classic. Bonus: it can be made ahead of time and reheats beautifully.
“FANTASTIC!! I sub peaches during the summer and add ginger and nutmeg. We cut into individual portions and top with Greek yogurt.”
What You’ll Need To Make Baked Oatmeal

- Old-fashioned rolled oats: The base of the dish; don’t substitute instant oats—they won’t give you the same hearty texture.
- Chopped walnuts or pecans, raisins & apples: These add-ins lend crunch, a touch of chewiness and sweetness, and tart, fruity flavor.
- Light brown sugar, cinnamon & vanilla: A well-balanced mix that sweetens the oatmeal and adds warm spice and depth of flavor.
- Baking powder: Helps the dish rise slightly.
- Butter, Eggs & Milk: This trio binds everything together and gives the oatmeal a rich and custardy texture.

Step-by-Step Instructions
Step 1: Mix the dry ingredients. In a large bowl, stir together the oats, half of the nuts, raisins, brown sugar, baking powder, salt, and cinnamon.

Step 2: Mix the wet ingredients. In a separate bowl, whisk the eggs, milk, and vanilla until well combined.

Step 3: Combine everything. Pour the custard and melted butter into the oat mixture and stir until evenly mixed.

Step 4: Layer the apples. Arrange the chopped apples in a greased baking dish.

Step 5: Assemble and top. Pour the oat mixture over the apples and sprinkle the remaining nuts on top.

Step 6: Bake. Bake at 325°F for about 40 minutes, until the oats are set and the top is golden. It’s just as tasty cold from the fridge the next day, so be sure to save a slice!

ADDITIONAL PRO TIPS
- Make it your own: You can swap the raisins for dried cranberries, chopped dates, currants, or skip them altogether.
- No nuts (or different nuts)? Instead of pecans, use slivered almonds or walnuts. Pumpkin seeds or sunflower seeds work too—or just leave them out.
- Meal prep win: Slice the baked oatmeal into squares, wrap individually, and store in the fridge or freezer for a grab-and-go breakfast.
- Best apple types: For the best results, use tart yet sweet baking apples, like Honey Crisp or Gala, which hold their shape when baked.

Wow, SO delicious! We loved the texture of this – I’m used to baked oatmeal that is more firm. I used one granny smith and one Fuji. We served it with FF plain greek yogurt to cut the sweetness. This will be a regular this fall!
I have an intolerance to milk, dont like almond can i usejust yogurt
Hi Pat, I’m afraid the yogurt might curdle. Sorry!
Can this be made in advance, refrigerated and baked the next morning?
Hi Janet, Yes that’s fine; you can also bake it ahead and reheat it.
Hi — Made this last night and reheated this morning. Loved it! Was wondering if you have the nutritional info for this dish? (Unless it’s on here somewhere and I missed it). Thanks!
Hi Barbara, So glad you enjoyed. Just added the nutritional info right underneath the recipe. Sorry about that — I have just recently started adding nutritional data and am still going back and updating older recipes.
what size pan do you use for this dish. Thinking of using individual ramekins. : )
Hi Connie, I use a 9-inch oval baking dish. Individual ramekins would be nice 🙂
Really good but waaaay too sweet for our household. I cut the brown sugar but will eliminate next time. Skipped the nuts and used craisens. Very good – will try again.
Terrific! I adore this blog;)
Brought this to a campout breakfast and warmed it by the fire. Everyone really liked it, especially as a somewhat healthy alternative to the bacon and egg type dishes that were the norm. Really nice to make this ahead of time for any breakfast occasion, and I’ll have fun mixing up the combinations with whatever I have on hand.
I love this recipe. I have made it a bunch of times with a bunch of different fruit/nut combo’s. Right now I have a apple/ blackberry combo in the oven baking for breakfast for the next 3 days for me and my husband. I use coconut oil over butter and coconut sugar over brown sugar. Yummy!!
awesome!!! 2 thumbs up! we loved it, and it is healthy, but tastes like cookies
Actually, I am eating cold leftover from yesterday as I write this. I am going to take some to my parents, as I think they will love it. This is definitely a keeper!
used vanilla almond milk instead of reg milk, turned out great!
