Ingredients
Full ingredients and substitutions are in the recipe box below.
- Rolled oats: old-fashioned oats give the best texture for this apple cinnamon baked oatmeal. Quick oats work but will be softer.
- Chopped apples: any apples work. We use firm apples like Honeycrisp, Fuji, Pink Ladies or Granny Smith for structure. Pears are a lovely substitute.
- Unsweetened applesauce: adds moisture and natural sweetness. Ripe bananas, ripe pear or pumpkin purée also work well. If you use bananas 2 mashed will be enough.
- Greek yogurt: adds creaminess and protein. Substitute low-fat Greek yogurt or Skyr for even more protein, or use plain dairy-free yogurt.
- Milk: any milk works. Try almond, oat, or soy milk for a dairy-free option in this simple apple breakfast recipe.
- Honey or maple syrup: both add gentle sweetness. You can also use date syrup or a little brown sugar.
- Egg: helps the oatmeal set and slice cleanly. For egg-free, use a flax or chia egg.
- Walnuts or pecans: add crunch and richness. Almonds or pumpkin seeds work too.
- Raisins (optional): bring chewy sweetness. Try chopped dates or dried cranberries instead.
- Cinnamon: key for warm flavor. Add a pinch of nutmeg for a cozy fall breakfast recipes twist.
- Vanilla extract: boosts sweetness. Almond extract works in small amounts.
- Baking powder: helps lift and lighten this Greek yogurt baked oatmeal.
How to Make Baked Apple Oatmeal
1. Preheat the oven
Preheat your oven to 375°F (190°C).
Lightly grease an 8 x 8 inch baking dish (or similar size) so nothing sticks. This small step makes serving much easier later.
2. Mix the wet ingredients
In a large bowl, add the applesauce, Greek yogurt, milk, honey, egg, and vanilla extract.
Whisk until smooth and creamy. Everything should look well combined, with no streaks of egg.
3. Add the oats
Stir in the rolled oats, cinnamon, baking powder, and a pinch of salt. Mix well so all the oats are coated and no dry spots remain.
4. Fold in apples and raisins
Gently fold in the chopped apples and raisins, if using.
5. Pour and top
Pour the mixture into the prepared baking dish.
Spread it out evenly with the back of a spoon so it bakes evenly. Sprinkle the chopped walnuts on top for crunch.
6. Bake and cool
Bake at 375°F (190°C) for 35 to 40 minutes.
The center should look set and the top lightly golden.
Let it cool for 5 to 10 minutes before slicing. This helps it firm up, making it perfect as a meal prep breakfast idea you can store and reheat later.
Tips
- Chop the apples thin and even: Small pieces soften better and help the oatmeal slice cleanly.
- No applesauce? No problem: You can replace it with 2 mashed ripe bananas. The flavor will be slightly sweeter but it works beautifully.
- Don’t skip the rest time: Let it cool 5–10 minutes after baking. This helps it set so you get neat slices.
- For extra crunch: Don’t mix the nuts into the batter. Sprinkle them on top instead before baking so they toast and get crispy in the oven.
- Soak raisins if dry: A quick 5-minute soak in warm water keeps them soft after baking.
- Make it ahead: It keeps well in the fridge and reheats beautifully in about 20 seconds in the microwave.
