Compared to traditional oatmeal, which cooks quickly but can be plain, this oatmeal apple breakfast bake takes a bit longer but rewards you with a texture that’s part-casserole, part-baked pudding — offering layers of soft oats and tender fruit, perfect for leisurely weekend breakfasts or meal prep.

Step-by-Step Instructions
Step 1: Preheat and Prep Your Baking Dish
Preheat your oven to 350°F (175°C). Lightly grease an 8×8-inch baking dish with coconut oil or butter to prevent sticking.
Step 2: Mix the Dry Ingredients
In a large bowl, combine the oats, baking powder, cinnamon, nutmeg, and salt. Stir these dry ingredients thoroughly to ensure even distribution of spices and leavening agents.
Step 3: Prepare the Wet Ingredients
In a separate bowl, whisk together the eggs, milk, maple syrup, vanilla extract, and melted coconut oil. Whisk until smooth and well blended.
Step 4: Combine Apples and Mixtures
Add the chopped apples to the dry ingredients, tossing to coat them evenly with the oat mixture. Pour the wet ingredients over the oat-apple mixture and stir gently until everything is well incorporated.
Step 5: Pour and Sprinkle Optional Toppings
Transfer the mixture to your prepared baking dish, spreading it out evenly. If desired, sprinkle walnuts, pecans, raisins, or a light dusting of brown sugar on top for added texture and sweetness.
Step 6: Bake to Perfection
Place the dish in the oven and bake for about 40 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.
Step 7: Cool and Serve
Allow the breakfast bake to cool for 5 to 10 minutes before slicing. Serve warm — it pairs wonderfully with a drizzle of yogurt, extra maple syrup, or a dollop of nut butter.
Chef’s Tip: For a crispier top, briefly broil at the end of baking, watching carefully to avoid burning.

Common Mistakes to Avoid Oatmeal apple breakfast bake
- Overbaking: The bake can dry out if left too long; aim for a golden top and moist center.
- Skipping the salt: A small amount of salt balances sweetness and enhances flavors — don’t omit it!
- Using instant oats: Instant or quick oats create a mushier texture; stick with old-fashioned rolled oats.
- Not greasing the pan: This can cause sticking and make serving difficult.
- Ignoring apple variety: Tart apples hold shape better and balance sweetness, preventing mushiness.
Following these tips helps ensure perfect texture, flavor, and presentation every time.
Storing Tips
To store your oatmeal apple breakfast bake:
- Cool completely before covering tightly with plastic wrap or transferring to an airtight container.
- Refrigerate for up to 4 days; reheat individual slices in the microwave or toaster oven for best results.
- For longer storage, freeze individual portions wrapped in parchment and foil for up to 2 months. Thaw overnight in the fridge before reheating.
- Avoid reheating in the oven without sufficient moisture, as it can dry the bake out excessively.
Proper storage retains freshness, flavor, and texture, making this recipe perfect for meal prepping breakfast.
