Why You’ll Love My Recipe

This recipe for baked apple oatmeal is loaded with apples! From sliced to grated apples, and then using applesauce; there is sure to be apple flavour in every bite. The recipe is gluten-free and also entirely vegan, using almond milk and chia egg (or flax egg) for binding. So you can rest assured that all dietary restrictions are being covered, without compromise on taste! It’s an apple oatmeal bake that is the perfect blend of healthy, wholesome and sweet.

It’s no secret that we absolutely LOVE oatmeal recipes in our home. Oatmeal bakes in particular are so easy to prep in advance and last well in the fridge to enjoy throughout the week. And after my Chocolate Chip Banana Baked Oatmeal and Blueberry Banana Baked Oatmeal were such a hit, I knew I wanted to develop a variation for apple season. The final result is a spin on my favourite Baked Apple Oatmeal Cups and Apple Pie Oatmeal.

Key Ingredient Notes

  • Rolled oats – I’m often asked what type of oats are best to use. For oatmeal bakes, I recommend old-fashioned oats or rolled oats. They have a chewy, soft texture and yield a creamy consistency without being too soft like quick oats often are. I use One Degree Organic Foods, Sprouted Rolled Oats. They bake beautifully in this recipe. 
  • Walnuts – I love the combination of apples and walnuts. They add a great, buttery, nutty crunch and are naturally rich in Omega-3 Fatty Acids, plant-based protein, and healthy fats! If preferred, swap in your favourite nuts, like crunchy pecans or almonds. 
  • Chia seeds – Ground chia seeds are used as an egg replacer and make this breakfast recipe naturally vegan. If you’re out of chia seeds, use ground flaxseeds to make a flax egg. 
  • Baking powder – A small amount of baking powder helps this bake rise and keeps the texture soft and fluffy. 
  • Grated apple – You’ll need 1 cup of freshly grated apple (this was about 2 small apples for me). I prefer the sweetness of Honeycrisp apples or pink lady apples, but feel free to use your favourite apple variety. You can even use one Honeycrisp and one granny smith for a sweet and tart combination. 
  • Apple sauce – Unsweetened applesauce not only adds a boost of fresh apple flavour, but adds natural sweetness without refined sugar. 
  • Almond milk – I like to use my creamy Homemade Almond Milk in this bake, but any store-bought plant-based milk will work well. My oat milk recipe would be a great alternative. 
  • Maple syrup – Sweet maple syrup enhances the sweetness in the apples without making this oatmeal breakfast recipe overly sweet. If needed, another liquid sweetener, such as agave or honey if not vegan will work well. 1/2 cup brown sugar or coconut sugar may work as a replacement, but you will need to add an additional splash of milk to compensate for the loss of liquid. 
  • Avocado oil – Helps to add moisture and makes this bake ultra soft and tender and encourages it to turn golden brown while baking. You can also try another oil, such as melted coconut oil or even vegan butter, if desired!

How to Make a Baked Apple Oatmeal 

It’s so easy to make this baked oatmeal recipe, even the most beginner home cooks can do it! 

First, add the rolled oats, baking powder, sea salt, cinnamon, hemp hearts, ground chia, and walnuts to an 8×11 baking dish. Mix to combine. 

Next, add the shaved apple, applesauce, almond milk, avocado oil, vanilla extract, and maple syrup over the oat mixture. Whisk the wet ingredients into the dry ingredients until evenly dispersed and combined. 

Finally, top with fresh apple slices and walnuts and bake for 30 minutes in an oven preheated to 350F/180C. When the apple cinnamon oatmeal bake is ready, it should be set in the centre and golden around the edges.

Let the wholesome breakfast bake cool for 10 minutes before cutting into slices and serving. Serve with a drizzle of maple syrup or almond butter, a dollop of coconut yogurt, and additional chopped walnuts, or as desired. Enjoy!

Storage and Reheating Tips 

Leftover oatmeal bake will keep in an airtight container in the refrigerator for up to 5 days. Alternatively, tightly cover the baking dish with plastic wrap or reusable wrap and refrigerate directly in the baking dish. Be sure to let the baked apple oatmeal cool completely before storing. 

This oatmeal bake is delicious cold, but to re-heat, slice into individual portions and microwave in a microwave-safe dish in 30 second increments (I usually microwave for a total of 1 to 2 minutes, depending on the serving size). 

Can You Freeze Baked Oatmeal?

Yes! You can freeze this baked apple oatmeal! Let it cool completely, cut and freeze the individual servings in freezer-safe containers. Microwave from frozen in 30 second increments until warm and cooked through. 

You can also freeze the entire bake (uncut). Before reheating, let the frozen bake thaw overnight in the refrigerator. The next morning, cover the top with tinfoil and pop in the oven at 350F for 20 to 25 minutes, or until completely thawed and warmed through.
