Ingredients You’ll Need

The ingredients for this Baked Apple Oatmeal Recipe are simple, but together they create that wonderful mix of creamy, sweet, and slightly tart flavors you crave in the morning. I always keep these staples on hand because they come together with a little honey and warm spices to elevate the oats and apples in the best way.

• Butter: Adding melted butter gives the oatmeal richness and a lovely golden crust; use softened butter to grease the pan for an easy release.
• Rolled Oats: These absorb the liquids well and keep a nice texture—don’t swap with quick oats or steel-cut oats here, or the baking time and texture will change.
• Baking Powder: Helps the oatmeal puff up just enough without being cakey.
• Ground Cinnamon: A cornerstone spice that complements apples perfectly; feel free to sprinkle extra on top before baking for a flavorful crust.
• Kosher Salt: Balances the sweetness and enhances all the cozy flavors.
• Freshly Grated Nutmeg: Adds a subtle warmth—freshly grated always beats pre-ground in flavor.
• Eggs: They bind everything together and help create that custardy texture inside.
• Whole Milk: For richness and moisture—substituting with plant-based milks can work, but results will vary slightly.
• Honey: For natural sweetness—add a touch more on top when serving if you like it really sweet.
• Pure Vanilla Extract: Brings depth and rounds out the flavors beautifully.
• Tart Apples: Granny Smiths are my go-to because their tang cuts through the richness, but any crisp, tart apple works well.
• Chopped Walnuts: For texture and earthy nuttiness—you can swap for pecans or leave out for nut-free.
• Plain Yogurt: Optional for serving but adds a creamy tang that pairs so well with the baked apples and oats.

Variations

I love playing around with this baked apple oatmeal recipe depending on what’s in season or what my family fancies. You absolutely should feel free to customize it too—adding your favorite fruit, nuts, or spices only makes it more yours!

• Add fresh berries: I’ve tossed in blueberries or raspberries for a sweet-tart pop that brightens up the dish in summer.
• Use other nuts: Pecans or sliced almonds work great if walnuts aren’t your favorite or to change things up.
• Go dairy-free: Swap whole milk with almond or oat milk and use coconut oil instead of butter—this still bakes beautifully.
• Spice it up: Try adding ground ginger or cloves along with the cinnamon and nutmeg for a more autumnal vibe.

How to Make Baked Apple Oatmeal Recipe

Step 1: Prep Your Dish and Oven

Start by preheating your oven to 350°F (175°C). Grease your baking dish—ideally a 13-by-9-inch or a 3-quart baking dish—with softened butter so the oatmeal doesn’t stick. I always find greasing well helps the edges brown nicely and makes serving much easier.

Step 2: Mix the Dry Ingredients

In a large bowl, whisk together the rolled oats, baking powder, ground cinnamon, kosher salt, and freshly grated nutmeg. Mixing the dry ingredients well at this stage ensures the spices and leavening are evenly distributed, so no bite tastes bland or overly spiced.

Step 3: Combine Wet Ingredients and Add to Dry

In a separate medium bowl, whisk the eggs, whole milk, honey, pure vanilla extract, and melted butter until smooth. Pour this mixture over the dry ingredients and stir gently until just combined—don’t overmix, or you risk a dense texture instead of a soft, tender bake.

Step 4: Fold in Apples and Walnuts, Then Bake

Stir in the chopped tart apples and walnuts. Then transfer the entire mixture evenly into your prepared baking dish. Bake for 40 to 45 minutes, until the oatmeal is set and golden brown around the edges, and the apples are tender. The smell while it’s baking? Pure magic—I swear it’s almost as good as eating it.

Step 5: Cool Slightly and Serve

Let the baked oatmeal cool for about 20 minutes before serving. I like to spoon it warm into bowls and add a generous dollop of plain yogurt, drizzle with a little extra honey, and sprinkle a pinch of cinnamon on top. This step really takes the final presentation and taste to the next level.

How to Serve Baked Apple Oatmeal Recipe

Garnishes

I always serve this baked apple oatmeal warm with a generous spoonful of plain yogurt on top—it adds a creamy, tangy contrast I adore. A little drizzle of honey or maple syrup seals the deal, along with a light dusting of cinnamon that makes it look as good as it tastes.

Side Dishes

If you want to round out the breakfast spread, a side of crispy bacon or breakfast sausage pairs unexpectedly well with the sweet and warm oatmeal. For a lighter accompaniment, fresh fruit salad or citrusy orange slices brighten the meal.

Creative Ways to Present

For a brunch or special occasion, I like to bake this oatmeal in small ramekins or muffin tins for individual portions—makes it feel a bit fancy and helps with serving. Topping with a sprinkle of toasted nuts and a mint leaf adds a pretty touch that always earns compliments.

Make Ahead and Storage

Storing Leftovers

I store leftover baked apple oatmeal covered in the fridge for up to 4 days. I find it holds its texture well, especially if you warm it gently rather than nuking it quickly, which can dry it out. Just cover with plastic wrap or store in an airtight container to keep the flavors fresh.

Freezing

This recipe freezes beautifully in individual portions—great for busy mornings! Simply cool completely, portion into freezer-safe containers or bags, and freeze for up to 2 months. When you want a quick breakfast, thaw overnight in the fridge or reheat from frozen in the microwave with a splash of milk.

Reheating

To reheat baked apple oatmeal, I prefer warming it in the oven at 325°F wrapped loosely in foil or in the microwave with a small splash of milk to keep it moist. This helps restore creaminess and avoids the dreaded dried-out texture. Add fresh toppings or yogurt after reheating for the best experience.
