Why You’ll Love This Recipe

  • Simple Ingredients: Uses common pantry staples and fresh apples for a fresh yet cozy vibe.
  • Make-Ahead Friendly: You can bake it in advance and reheat for a quick, nourishing breakfast.
  • Naturally Sweetened: Maple syrup and apples provide gentle sweetness without refined sugar overload.
  • Kid-Approved Comfort: My family goes crazy for this warm, soft oatmeal that sneaks in healthy nuts and fruit.

Ingredients You’ll Need

The harmony between the hearty oats, crunchy walnuts, and sweet apples really makes this recipe shine. I’ve found that using rolled oats gives you the perfect chewy texture without being too mushy, and the warming spices like cinnamon and ginger elevate the flavors beautifully.

  • Rolled oats: These absorb liquid nicely and hold up well during baking, unlike quick oats which can get mushy.
  • Chopped walnuts: Adds a delightful crunch and nuttiness; feel free to swap for pecans if that’s what you have on hand.
  • Ground cinnamon: The star spice here, it brings that classic apple-pie aroma you’ll fall in love with.
  • Ground ginger: Just a hint gives a lovely warm undertone without overpowering the dish.
  • Salt: Balances the sweetness and enhances all the other flavors.
  • Diced apples: Use a crisp variety like Honeycrisp or Granny Smith for a nice texture contrast.
  • Applesauce: Keeps the oatmeal moist and adds extra apple flavor without extra chopping.
  • Milk or almond milk: Use your favorite milk — I love the subtle nuttiness almond milk adds here.
  • Eggs: They bind everything together and give the oatmeal a custardy texture.
  • Maple syrup: My go-to natural sweetener; it complements apples perfectly.
  • Pure vanilla extract: Adds depth and rounds out the sweetness.
  • Pure almond extract: Just a drop for a hint of complexity and nutty aroma.
  • Coconut oil: Melted and slightly cooled—this adds moistness and a subtle tropical warmth without strong coconut flavor.

Variations

One of the best things about this baked apple oatmeal recipe is how easy it is to tweak it to fit your mood or dietary needs. I love mixing it up depending on what’s in my pantry or what my family craves.

  • Vegan Variation: Swap eggs for flax eggs and use a plant-based milk. I once made this for a friend’s brunch and nobody even guessed it was vegan!
  • Seasonal Twist: Add a handful of dried cranberries or raisins in fall or chopped fresh pears in winter for extra fruitiness.
  • Extra Crunch: Sprinkle some toasted oats or granola on top before baking to up the texture game – my kids love this little surprise.
  • Lower Sugar Option: Cut back on the maple syrup and add a natural sweetener like mashed banana or a splash of orange juice.

How to Make Baked Apple Oatmeal Recipe

Step 1: Prep the Oven and Baking Dish

Start by positioning your oven rack in the center and preheat to 350°F. Lightly grease an 8-by-8-inch glass baking dish or use a nonstick spray. I like glass because it heats evenly and you can visually check how baked the oatmeal is getting without opening the oven. Little things like this help avoid underbaking or burning!

Step 2: Mix Dry Ingredients

In a large bowl, combine rolled oats, chopped walnuts, ground cinnamon, ground ginger, and salt. Mixing the dry ingredients first means every spoonful gets that perfect blend of warm spices and crunch. I always sniff this mixture at this stage—such a cozy smell!

Step 3: Stir in Wet Ingredients and Apples

Now toss in the diced apples and applesauce, then pour in the milk, eggs, maple syrup, vanilla, and almond extract. Finally, stir in the melted coconut oil until everything looks well combined. A quick tip: make sure your milk and eggs are at room temperature so the coconut oil doesn’t clump back up — I learned this the hard way and it made my batter weirdly chunky!

Step 4: Bake and Enjoy

Spread that lovely mixture evenly into your prepared dish and bake for about 30 minutes, or until it’s set and the top turns a light golden brown. When I peek through the oven window, I look for tiny bubbles at the edges and that slightly cracked top as a clue that it’s ready. Let it cool for at least 5 minutes (if you can wait!) before slicing and serving warm. The finish is wonderfully custardy and comforting.

Pro Tips for Making Baked Apple Oatmeal Recipe

  • Room Temperature Is Key: Always bring milk and eggs to room temp to help coconut oil blend in smoothly.
  • Don’t Overmix: Stir just until combined to keep a nice texture rather than a dense baked oatmeal.
  • Choose Crisp Apples: Firmer apple varieties hold their shape better after baking and add a great texture contrast.
  • Let It Rest: Cooling enables the oatmeal to set properly, making it easier to slice neat squares.

Garnishes

I love drizzling a little warm milk or a splash of cream on top — it melts into the warm oatmeal and amps up the comfort factor. A sprinkle of extra chopped walnuts or a dusting of cinnamon is a simple way I like to add a little finishing touch that feels special every time.

Side Dishes

Pairing this baked apple oatmeal with a side of Greek yogurt or a small fruit salad gives you a nice balance of creamy and fresh alongside the warmly spiced oats. On busier mornings, I’ll just top my oatmeal with a scoop of nut butter for an extra protein boost.

Creative Ways to Present

For holiday mornings or brunch parties, I’ve served this baked apple oatmeal in individual ramekins or mini mason jars. Topping each with a cinnamon stick or a sprig of fresh mint gives it that wow factor. It’s a crowd-pleaser both in taste and presentation!

Make Ahead and Storage

Storing Leftovers

I keep leftovers covered tightly in the fridge for up to 4 days. The texture changes slightly as it cools off, but when reheated, it’s just as comforting and delicious. I usually cut it into squares beforehand to make reheating individual portions easier.

Freezing

Freeze any uneaten baked apple oatmeal in single servings wrapped in plastic wrap and stored in freezer bags. When you want a quick breakfast, just thaw overnight in the fridge and warm it up the next morning — still tastes great!

Reheating

I reheat leftovers on a microwave-safe plate with a drizzle of milk to prevent it from drying out. About 30 seconds usually does the trick, but if you’re reheating a larger portion, add 10-15 seconds more as needed. It comes out creamy and just as cozy as fresh out of the oven.

FAQs

  1. Can I use steel-cut oats instead of rolled oats in this baked apple oatmeal recipe?

    Steel-cut oats have a much firmer texture and longer cooking time, so they’re not ideal for this recipe. Rolled oats soften nicely during baking, creating the perfect custardy texture you want. If you want to try steel-cut oats, you’d need to cook them separately before baking, which can be a hassle.

  2. Can I make this baked apple oatmeal recipe dairy-free?

    Absolutely! Just swap the milk for any plant-based milk like almond, oat, or soy milk. Using coconut oil instead of butter keeps things dairy-free as well. I’ve made this dairy-free many times and it still comes out deliciously moist and flavorful.

  3. How do I store leftovers of this baked apple oatmeal recipe?

    Store leftovers in an airtight container in the fridge for up to 4 days. For longer storage, freeze individual portions wrapped tightly. When reheating, add a splash of milk to keep it creamy and prevent drying out.

  4. Can I add other fruits or nuts to this recipe?

    Definitely! You can toss in dried cranberries, chopped pears, or raisins for different flavors. Substitute walnuts with pecans or almonds. Just keep quantities similar so the texture and baking time stay balanced.

Final Thoughts

This baked apple oatmeal recipe has become a staple in my home, especially during cooler months when I crave warmth and comfort in every bite. It’s comforting, easy to make, and forgiving enough for kitchen newbies. I love that it sneaks in wholesome ingredients while feeling indulgent, and sharing it always makes mornings a little brighter. Give it a try—you might just discover your new favorite breakfast!

  • ¼ teaspoon salt

Fruit

  • 1 cup diced apples (about 1 medium apple)
  • ½ cup applesauce

Wet Ingredients

  • ½ cup milk or almond milk (room temperature)
  • 2 eggs (room temperature)
  • ¼ cup maple syrup
  • 1 teaspoon pure vanilla extract
  • ¼ teaspoon pure almond extract
  • ¼ cup coconut oil (melted and slightly cooled)


Instructions

  1. Preheat Oven and Prepare Dish: Position the oven rack in the center and preheat the oven to 350°F (175°C). Lightly grease or spray an 8- by 8-inch glass baking dish with nonstick cooking spray to prevent sticking.
  2. Combine Dry Ingredients: In a large mixing bowl, mix together the rolled oats, chopped walnuts, ground cinnamon, ground ginger, and salt until evenly distributed to ensure every bite is flavorful.
  3. Add Fruit and Wet Ingredients: Stir in the diced apples, applesauce, milk, eggs, maple syrup, vanilla extract, and almond extract to the dry mixture. Mix well to combine all ingredients thoroughly.
  4. Incorporate Coconut Oil: Pour in the melted and slightly cooled coconut oil. Stir gently until the mixture is uniform and all components are well incorporated.
  5. Spread and Bake: Transfer the oatmeal mixture evenly into the prepared baking dish. Bake in the preheated oven for 30 minutes or until the top is set and lightly golden brown, indicating it is cooked through.
  6. Cool and Serve: Remove from the oven and let the oatmeal cool in the baking dish for at least 5 minutes before slicing. Serve warm, optionally drizzling with extra warm milk and sprinkling additional chopped walnuts on top for extra texture and flavor.

Notes

  • For best results, ensure milk and eggs are at room temperature to prevent the coconut oil from solidifying when mixing. You can warm eggs by placing them in warm water for a few minutes and microwave milk for 20 seconds.
  • To reheat leftover baked oatmeal, place a serving on a plate, drizzle with milk, and microwave for about 30 seconds for a warm, comforting breakfast.
