How to Make Baked Apple Oatmeal Recipe
Step 1: Prepare Your Pan
Start by preheating your oven to 375°F and giving your baking dish a quick spritz with nonstick spray. Whether you use an 8×8 or 9×9-inch pan, this step ensures your baked oatmeal comes out effortlessly without sticking.
Step 2: Whisk the Wet Ingredients
In a large bowl, whisk the eggs until frothy and then add the milk, applesauce, and maple syrup. Whisk everything together until it’s perfectly combined. This mixture is the flavor-packed liquid base that will soak into those oats for a creamy texture.
Step 3: Add Spices and Leavening
Sprinkle in the baking powder, cinnamon, apple pie spice, and salt, then whisk again. These pantry staples are the secret to the warm, inviting aroma and that lovely rise in the oatmeal’s texture.
Step 4: Fold in the Oats and Apples
Stir in the oats and three-quarters of your chopped apples. The oats soak up the wet ingredients, and the apples provide tasty pockets of freshness and sweetness throughout.
Step 5: Rest the Mixture
Cover the bowl and allow the mixture to sit at room temperature for 10 minutes. This step is key, giving the oats time to absorb the liquid fully, which results in a soft, luscious baked oatmeal.
Step 6: Transfer and Top
Pour the mixture into your prepared baking pan and sprinkle the remaining apple pieces evenly over the top—these will create gorgeous apple-topped bites that make the dish so irresistible.
Step 7: Bake to Perfection
Bake for 30 to 40 minutes until the edges are golden and the center feels firm, not jiggly. Let the baked apple oatmeal cool for 15 minutes before slicing so it sets up nicely.

FAQs
Can I use steel-cut oats for this Baked Apple Oatmeal Recipe?
Steel-cut oats are a bit too firm and take longer to cook, so they won’t soften sufficiently within the baking time. Old-fashioned oats are best for the perfect balance of texture and tenderness here.
Is it possible to make this recipe dairy-free?
Absolutely! You can swap regular milk for any plant-based alternative like almond, oat, or soy milk without affecting the delicious flavor or texture.
Can I prepare this recipe the night before?
Yes! Mix all the ingredients and cover the baking dish, then refrigerate overnight. In the morning, simply bake it fresh for a convenient and warm breakfast ready when you are.
What kind of apples work best?
Tart apples like Granny Smith add a nice tang that balances the sweetness nicely, but sweeter varieties like Fuji or Honeycrisp work beautifully too, depending on your preference.
How do I know when the baked oatmeal is done?
Look for a lightly golden top and edges pulling away slightly from the pan. The center should be set and not jiggly—if unsure, a toothpick inserted into the center should come out mostly clean.
