This hearty Healthy Baked Apple Oatmeal has become my go-to breakfast option for busy mornings and lazy weekends alike. Combining the wholesome goodness of oats with the natural sweetness of apples and maple syrup, this baked delight delivers both nutrition and comfort in every bite.
I first created this recipe during a particularly hectic week when I needed breakfasts I could prepare once and enjoy for days. Now it has become a Sunday ritual in our home, filling the kitchen with the comforting aroma of cinnamon and baked apples.
Ingredients
- Old fashioned rolled oats: the star ingredient providing fiber and hearty texture. Choose thick cut oats for the best results
- Almond milk: adds creaminess without dairy. The subtle nutty flavor complements the apples beautifully
- Fresh apples: provides natural sweetness and moisture. Choose firm varieties like Honeycrisp or Granny Smith
- Chopped pecans: adds essential healthy fats and a satisfying crunch
- Maple syrup: brings natural sweetness. Opt for pure maple syrup rather than pancake syrup
- Olive oil: contributes healthy fats and prevents dryness. Use a light variety to avoid overpowering
- Egg: acts as a binder to hold everything together. Brings protein to the breakfast
- Warming spices: cinnamon ginger and nutmeg create that classic apple pie flavor profile
Step-by-Step Instructions
- Prepare Your Space:
- Preheat your oven to 350°F and take time to properly grease an 8x8 baking dish. I find a light coating of cooking spray works perfectly but butter also creates a nice flavor. Make sure to cover the corners where sticking often occurs.
- Combine All Ingredients:
- In a large mixing bowl add all ingredients at once. Gently stir until everything is well incorporated making sure the egg is fully beaten throughout and the spices are evenly distributed. The consistency will be quite wet which is exactly what you want.
- Transfer and Bake:
- Pour the mixture into your prepared baking dish spreading it evenly to the corners. It will appear to have too much liquid but this is normal. The oats will absorb this moisture during baking creating the perfect texture. Bake uncovered for 35 to 40 minutes until the top turns golden brown and all liquid has been absorbed.

The cinnamon in this recipe is really the secret ingredient that makes everything shine. I discovered years ago that using high quality Ceylon cinnamon rather than the more common Cassia variety adds a complex sweetness without any bitter notes. My grandmother always said good cinnamon was worth the extra cost and this recipe proves her right every time.
Storage Recommendations
This baked oatmeal maintains its quality remarkably well when properly stored. After cooling completely divide it into individual portions in airtight containers and refrigerate for up to a week. The flavor actually develops nicely after a day in the refrigerator with the spices becoming more pronounced. For longer storage wrap individual portions tightly in plastic wrap then place in freezer bags where they will keep for up to three months. Thaw overnight in the refrigerator before reheating.
Customization Options
This recipe welcomes creative adaptations based on seasonal availability and personal preferences. In summer replace apples with fresh berries like blueberries or sliced strawberries. Fall calls for pears or pumpkin puree with extra cinnamon. Winter is perfect for adding dried cranberries and orange zest. The nuts can be swapped too walnuts provide excellent omega3s while sliced almonds offer a lighter crunch. For a tropical twist try coconut milk instead of almond milk and add diced pineapple and shredded coconut.
Serving Suggestions
While delicious on its own this baked oatmeal reaches new heights with thoughtful accompaniments. Warm portions can be topped with a dollop of Greek yogurt which adds protein and creates a pleasing temperature contrast. A drizzle of additional maple syrup or honey brings extra sweetness for those with a sweet tooth. Fresh fruit like sliced bananas or berries adds vibrant color and nutritional value. For special occasions try serving with a scoop of vanilla yogurt and a sprinkle of granola for added crunch.
