Apple Baked Oatmeal is a minimum effort, healthy, make-ahead vegan breakfast casserole that is full of hearty oats, chopped apples and spices. Bake it up at the weekend and enjoy it served warmed or cold for breakfast all week long!
This apple baked oatmeal is such a convenient and easy-to-make vegan breakfast and one of my favourites. Chop the apples, mix everything up in a bowl, bake, then enjoy it all week long!
If you aren't a fan of regular stovetop oatmeal but want to enjoy oats for breakfast this apple baked oatmeal or my strawberry baked oatmeal are fantastic alternatives.
Once baked it slices up well and has a chewy and soft (but not too soft) oaty bar-like texture, punctuated with pieces of sweet chopped apple and crunchy nuts. It tastes like apple pie and is perfect for people who want to learn to like oatmeal because of the health benefits but dislike the porridge-like texture.
What ingredients & equipment do I need?
For detailed measurements and instructions, see the printable recipe card.
To make apple baked oatmeal you need some basic pantry-friendly ingredients. Here's a quick visual and below that I explain a bit more about each ingredient and why it's needed:
- Apples - Regular eating apples are fine. Any kind.
- Oats - Old-fashioned or rolled oats are needed for this recipe. Porridge oats if you are in the UK. Don't use steel-cut oats or quick oats. Use certified gluten-free oats if you need the oatmeal to be gluten-free.
- Sugar - Any type you have is fine. White, golden, brown or coconut sugar. You can also use the same amount of maple syrup instead.
- Ground flaxseed - A common ingredient in vegan baking. If you don't have any you can omit it but the baked oatmeal won't hold together as well when sliced.
- Walnuts or pecans - For great nutty flavour and crunch. If you don't have any or can't eat nuts for whatever reason you can safely omit them or use pumpkin seeds instead.
- Cinnamon, ginger, vanilla, salt - For flavour. Both cinnamon and ginger work really well with apples. If you don't have ginger though just cinnamon is ok.
- Non-dairy milk - Any kind. For moisture. It all gets soaked up as the oats bake and there is no visible milk remaining once it's done.
- Nut/seed butter - For healthy fats and satiety. These baked oats really do keep you feeling full for hours. Any nut or seed butter will do. I really like to use almond butter in mine! You can use ¼ cup of oil instead of the nut butter if you prefer but nut/seed butter adds healthy fats and keeps you feeling fuller longer.
You will also need an oven-proof dish. Anything from a ceramic casserole dish to a cast iron skillet to a cake pan. Just make sure it can hold about 2.5 quarts/litres.
How to make Apple Baked Oatmeal
Apple Baked Oatmeal is incredibly easy to make. Here's how:
- Mix the dry ingredients together in a large bowl.
- Mix the milk, vanilla and nut butter together in another bowl. Start by mashing the nut butter with a fork into a little bit of milk and gradually add more as you work out the bigger lumps. Some small lumps are fine! Or you can blend it all together in a blender. It makes it quicker to get the nut butter mixed in.
- Add the chopped apple to the dry ingredients.
- Pour in the liquid mixture and mix well.
- Spoon into an ovenproof dish.
How to serve
Serve Apple Baked Oatmeal either cold, warm or hot. It's great fresh from the oven but also keeps incredibly well. I either eat mine cold or pop it in the microwave for a minute or two to warm it up.
My favourite way to serve it is with a dollop of vegan yogurt and a drizzle of maple syrup. It's also good with some non-dairy milk poured over and eaten more like traditional breakfast cereal.
Other accompaniments that would work with apple and cinnamon baked oats are applesauce, apple butter or stewed apples, a drizzle of nut butter, a scattering of berries like raspberries or blackberries, or some toasted nuts or seeds.
Storage and reheating tips
Once cool, cover and refrigerate the apple cinnamon baked oatmeal for up to 7 days. You can even slice it up and pop it into individual-sized containers to make your mornings even easier.
Apple Baked Oatmeal also freezes well for up to 3 months. I recommend freezing individual portions so that you can take out only what's needed. Let it defrost in the fridge overnight.
Enjoy cold or reheat. Simply pop an individual serving in a bowl in the microwave for a minute or two. Or you can put it on an oven-proof plate/dish and bake for about 10 minutes at 350°F (175°C). If using the microwave it will stay nice and moist, whereas the oven will dry it out a little so be sure to serve it with some vegan yogurt, maple syrup or a drop of plant milk if necessary to moisten it up.
Apple baked oatmeal is really easy to customize. Add a handful or two of blackberries, raspberries or blueberries when they are in season. Or keep the base recipe the same and swap out the apples for any other chopped fruit or fresh or frozen berries. Anything goes. My favourite fruits to use are blueberries, peaches (check out my peach & blueberry baked oatmeal), strawberries, banana, pear and frozen raspberries.
You can either omit the spices or switch them up to suit whatever fruit you're using and you can even throw in some dried fruit too. Raisins, dried cranberries and chopped dates are great in it. How about we don't rule out a handful of chocolate chips too ;O)
Apple baked oatmeal for one
You can safely scale this baked oatmeal recipe down to make a smaller batch, or make it in individual baked apple oatmeal cups by baking it in a muffin pan. Use liners and fill them to the top then bake for about 20 to 25 minutes or until they are turning golden and feel firm. Allow the baked apple oatmeal cups to cool then refrigerate or freeze for up to 3 months. Take one or two out to defrost as you need them.

Apple Baked OatmealAuthor:
- 2¾ cups / 248 grams rolled oats , or old fashioned oats (porridge oats in the UK)
- ½ cup / 100 grams sugar
- ½ cup / 55 grams chopped walnuts , or pecans (omit for nut-free)
- 2 tablespoons / 14 grams ground flax
- 2 teaspoons ground cinnamon
- ½ teaspoon ground ginger
- ½ teaspoon fine salt
- ¼ cup / 4 tablespoons nut or seed butter , of choice (or the same amount of oil)
- 1½ cups / 360 mls milk of choice
- 1 tablespoon vanilla extract
- 2 to 3 medium apples , (use as much or as little as you like)
- Preheat oven to 375° F (190 °C) and have a large oven-proof dish or pan ready. One that will hold a minimum of 2 quarts/ litres. The pan I use in the photos is 2.5 quarts. Anything ovenproof will do, such as a ceramic dish, skillet or 8 x 8 cake pan.
- To a large bowl add the oats, sugar, nuts, ground flaxseed, cinnamon, ginger and salt. Mix together to combine.
- To another smaller bowl add the nut/seed butter then gradually add the milk to work out the big lumps until it's mostly combined. Some small lumps are fine. Mashing with a fork makes it easier. Then add the vanilla. If you have a blender you can blend it altogether if you want to be super quick.
- Core the apples and chop into small ½ inch chunks. There is no need to peel them unless you want to. The colour of the skin is nice in the finished oatmeal. If you want to decorate the top of the oatmeal keep half an apple aside and slice it thinly.
- Add the chopped apple to the dry ingredients then pour over the milk mixture. Give it a really good stir so you can no longer see any dry ingredients and so the apple is distributed througout. .
- Spoon into the oven-proof dish or pan, push it down with a spoon or spatula to level the top and add some apple pieces for decoration if desired.
- Bake for 40 mins.
