Ingredients
Instructions
1. Preheat your oven to 375 F (190 C). Lightly grease an 8×8 inch or 9×9 inch baking dish with butter or coconut oil.
2. In a large mixing bowl, whisk together the old-fashioned rolled oats, ground cinnamon, ground nutmeg, baking powder, and salt. Make sure these are well combined so the spices are evenly distributed throughout the oatmeal.
3. In a separate medium bowl, whisk together the milk, maple syrup (or honey), egg, and vanilla extract until smooth. The egg acts as a binder, helping the oatmeal hold its shape.
4. Pour the wet ingredient mixture into the bowl with the dry ingredients. Stir well until the oats are thoroughly moistened.
5. Gently fold in the diced apples. Make sure they are evenly distributed throughout the oat mixture.
6. Pour the oatmeal mixture into your prepared baking dish, spreading it evenly. If desired, drizzle a tablespoon of melted butter or coconut oil over the top for extra richness and a golden crust.
7. Bake for 30-35 minutes, or until the top is golden brown and the oatmeal is set in the center. A good visual cue is when the edges start to pull away slightly from the sides of the dish.
8. Remove from the oven and let it cool for a few minutes before serving. This allows the oatmeal to firm up slightly, making it easier to portion.

Everything You Need To Make This Recipe Without Stress
Gathering your ingredients for this baked oatmeal is straightforward, and most items are likely already in your pantry. We’re focusing on simple, wholesome components that come together to create a delicious and nutritious dish.
INGREDIENTS:

- 2 cups old-fashioned rolled oats
- 1 teaspoon ground cinnamon
- 1/4 teaspoon ground nutmeg
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 2 cups milk (dairy or non-dairy)
- 1/4 cup maple syrup or honey
- 1 large egg
- 1 teaspoon vanilla extract
- 2 medium apples, peeled, cored, and diced
- 2 tablespoons melted butter or coconut oil (for greasing and topping, optional)
For the milk, feel free to use any type you prefer. Whole milk will give a richer result, while skim milk or non-dairy options like almond, soy, or oat milk work beautifully for a lighter or dairy-free version. If you don’t have maple syrup, honey is a perfect substitute, offering a similar natural sweetness. When it comes to apples, firm, slightly tart varieties like Honeycrisp, Fuji, Gala, or Granny Smith hold their shape well and offer a great flavor contrast. You can also mix and match apple types for more complexity.

How To Make It Step By Step With Visual Cues

Creating this healthy apple cinnamon baked oatmeal is incredibly simple. Follow these steps for a perfect outcome every time.
- Prepare Your Baking Dish: Preheat your oven to 375°F (190°C). Lightly grease an 8×8 inch or 9×9 inch baking dish with butter or coconut oil. This prevents sticking and makes for easy serving.
- Combine Dry Ingredients: In a large mixing bowl, whisk together the old-fashioned rolled oats, ground cinnamon, ground nutmeg, baking powder, and salt. Make sure these are well combined so the spices are evenly distributed throughout the oatmeal.
- Mix Wet Ingredients: In a separate medium bowl, whisk together the milk, maple syrup (or honey), egg, and vanilla extract until smooth. The egg acts as a binder, helping the oatmeal hold its shape.
- Combine Wet and Dry: Pour the wet ingredient mixture into the bowl with the dry ingredients. Stir well until the oats are thoroughly moistened.
- Fold in Apples: Gently fold in the diced apples. Make sure they are evenly distributed throughout the oat mixture.
- Transfer to Baking Dish: Pour the oatmeal mixture into your prepared baking dish, spreading it evenly. If desired, drizzle a tablespoon of melted butter or coconut oil over the top for extra richness and a golden crust.
- Bake Until Golden: Bake for 30-35 minutes, or until the top is golden brown and the oatmeal is set in the center. A good visual cue is when the edges start to pull away slightly from the sides of the dish.
- Cool and Serve: Remove from the oven and let it cool for a few minutes before serving. This allows the oatmeal to firm up slightly, making it easier to portion.
Easy Variations And Serving Ideas That Fit Real Life
This apple cinnamon baked oatmeal is fantastic on its own, but it’s also a wonderful canvas for customization. For a kid-friendly twist, you can add a handful of chocolate chips to the mixture before baking, or sprinkle some mini marshmallows on top during the last 5 minutes of baking. If you’re looking for more texture, stir in a quarter cup of chopped nuts like walnuts or pecans, or some dried cranberries or raisins along with the apples. For an extra boost of protein and healthy fats, a tablespoon of chia seeds or ground flaxseed can be mixed in with the dry ingredients.
When serving, a dollop of Greek yogurt or a drizzle of extra maple syrup can elevate the dish. A splash of milk or cream over a warm slice is also a classic addition. For a brunch spread, cut the baked oatmeal into squares and arrange them on a platter with fresh berries on the side. It’s also delicious with a scoop of nut butter for added richness and protein.
Common Slip-Ups And How To Avoid Them
Even simple recipes can have common pitfalls. Being aware of these can help ensure your baked oatmeal turns out perfectly every time.
- Using Instant Oats: Avoid using instant or quick-cooking oats. They absorb liquid too quickly and will result in a mushy, less satisfying texture. Old-fashioned rolled oats are crucial for the right chewiness and structure.
- Overmixing the Batter: While you want the ingredients to be well combined, overmixing can sometimes lead to a tougher texture. Mix just until the wet and dry ingredients are incorporated and the oats are moistened.
- Not Greasing the Dish: Forgetting to grease your baking dish can lead to the oatmeal sticking, making it difficult to remove and serve neatly. A light coat of butter or coconut oil is all it takes.
- Underbaking: If the oatmeal isn’t fully set in the center, it can be too soft or crumbly. Look for a golden-brown top and edges that are pulling away from the dish, indicating it’s cooked through. A toothpick inserted into the center should come out mostly clean.
- Overcrowding with Apples: While apples are delicious, too many can add excessive moisture, making the oatmeal watery. Stick to the recommended amount for the best texture.
How To Store It And Make It Ahead Without Ruining Texture
This baked oatmeal is a fantastic candidate for meal prepping, as it stores and reheats beautifully.
- Storing Leftovers: Once completely cooled, cover the baking dish tightly with plastic wrap or transfer individual portions to airtight containers. Store in the refrigerator for up to 4-5 days.
- Reheating: To reheat, simply place a portion in the microwave for 1-2 minutes, or until warmed through. For a crispier texture, you can reheat individual slices in a toaster oven or conventional oven at 350°F (175°C) for about 10-15 minutes.
- Making Ahead: You can assemble the entire dish the night before. Simply combine all ingredients in the greased baking dish, cover tightly with plastic wrap, and refrigerate overnight. In the morning, preheat your oven and bake as directed, adding an extra 5-10 minutes to the baking time since it’s starting from cold. This makes for an incredibly easy morning!
- Freezing: For longer storage, individual portions can be frozen for up to 2-3 months. Wrap slices tightly in plastic wrap, then place them in a freezer-safe bag or container. Thaw overnight in the refrigerator before reheating.
