Applesauce Baked Oatmeal

I spent years making stovetop oatmeal and never once got excited about it.

It was fine. It filled me up. But "fine" is not why I cook.

The first time I pulled a pan of applesauce baked oatmeal out of the oven, the kitchen smelled like warm apple pie, and the top had this golden, slightly caramelized crust.

I cut into it and it held together in clean squares, not a bowl of mush.

My wife grabbed a piece before I could even set the pan down.

Now I make a batch every Sunday and we eat it all week.

It reheats in the microwave in about 30 seconds and tastes just as good on Thursday as it did on Monday.

The applesauce brings all the natural sweetness and moisture you need, so the oatmeal stays soft and tender without being heavy.

One pan, 45 minutes, and you've got breakfast handled for the entire week.

If you've been looking for a reason to love oatmeal, this is it.

Why You'll Love This Recipe

This is the oatmeal recipe that finally made me a morning person.

• Tastes like apple pie. Cinnamon, applesauce, and diced apples create that warm, spiced flavor you'd get from a fresh-baked pie.
• Naturally sweet from applesauce. You can use less added sweetener than most baked oatmeal recipes because the applesauce does a lot of the work.
• One-bowl prep. Mix wet, mix dry, combine, pour, bake. No special equipment needed.
• Perfect for meal prep. Cut into squares, store in the fridge, and reheat all week. It's a grab-and-go breakfast that actually tastes good.
• Kid-approved. Every kid I've served this to has gone back for seconds. The apple pie flavor wins them over every time.

Ingredients You'll Need

Everything here is a basic pantry staple, plus some fresh apples.

• Rolled oats (3 cups). The backbone of the dish. They give the baked oatmeal a hearty, chewy texture.
• Ground cinnamon (2 teaspoons). This is what makes it taste like apple pie. Don't skimp on it.
• Baking powder (1 teaspoon). Gives the oatmeal a slight lift so it's not flat and dense.
• Salt (½ teaspoon). Brings out the sweetness and balances the spice.
• Milk (1 ½ cups). Any variety works. Dairy, almond, oat, or soy.
• Unsweetened applesauce (½ cup). Adds moisture and natural sweetness. This is what keeps the oatmeal from drying out.
• Maple syrup (⅓ cup). A little goes a long way. You can reduce this to ¼ cup if you like it less sweet.
• Eggs (2 large). They help bind everything together and give the oatmeal a firmer, sliceable texture.
• Vanilla extract (1 teaspoon). Rounds out the flavor and adds warmth.
• Diced apples (2 cups, about 2 small apples). Fresh apple pieces reinforce the apple flavor and add texture throughout.
• Chopped pecans or walnuts (½ cup, optional). For crunch on top. I almost always add these.

Ingredient Notes and Substitutions

• Rolled oats vs. quick oats. Rolled oats give you a chewier, more structured baked oatmeal. Quick oats work in a pinch but the result will be softer and creamier, more like a pudding than a sliceable square.
• Applesauce: sweetened vs. unsweetened. Always go with unsweetened so you can control the sugar. If all you have is sweetened, reduce the maple syrup to 2 tablespoons.
• Milk options. Whole milk or oat milk give the creamiest result. Almond milk and soy milk both work well too.
• Sweetener swaps. Brown sugar can replace maple syrup. Use ⅓ cup packed brown sugar and add it to the dry ingredients. Honey works as a 1:1 swap for maple syrup.
• Egg-free option. For a vegan version, use 2 flax eggs: mix 2 tablespoons ground flaxseed with 5 tablespoons water and let it sit for 5 minutes until it thickens.

How to Make Applesauce Baked Oatmeal

This is a simple mix-and-bake recipe that comes together in about 10 minutes of hands-on time.

Step 1: Prep and Preheat

Preheat your oven to 350°F.

Grease an 8x8 or 9x9 inch baking dish with non-stick spray or line it with parchment paper.

Step 2: Mix the Dry Ingredients

In a large bowl, combine the 3 cups rolled oats, 2 teaspoons cinnamon, 1 teaspoon baking powder, and ½ teaspoon salt.

Give it a quick stir to distribute the spices evenly.

Step 3: Mix the Wet Ingredients

In a separate bowl, whisk together the 1 ½ cups milk, ½ cup applesauce, ⅓ cup maple syrup, 2 eggs, and 1 teaspoon vanilla.

Step 4: Combine and Bake

Pour the wet ingredients into the dry and stir until everything is mixed.

Fold in the 2 cups diced apples.

Transfer the mixture to your prepared baking dish and smooth the top with a spatula.

Sprinkle the chopped pecans on top if you're using them.

Bake for 35 to 40 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.

Let it cool for 5 to 10 minutes before slicing. It firms up as it cools.

Tips for the Best Baked Oatmeal

Small details that make a noticeable difference.

• Don't overmix. Stir just until the wet and dry ingredients are combined. Overmixing can make the texture gummy.
• Use ripe apples. Sweeter varieties like Honeycrisp or Gala add the most flavor. Granny Smith works if you want a tart contrast.
• Dice the apples small. Small pieces distribute more evenly and help the oatmeal hold together when you cut it into squares.
• Grease the pan well. Or use parchment paper. Baked oatmeal loves to stick, and a well-greased pan makes removal painless.
• Check doneness with a toothpick. It should come out clean or with just a few moist crumbs. If the batter is still wet, give it another 5 minutes.
• Let it cool before cutting. The oatmeal continues to set as it cools. Cutting too early gives you crumbly pieces. Wait at least 5 minutes.

Add-Ins and Variations

This recipe takes to add-ins like a champ.

• Blueberries. Fold in ½ cup fresh or frozen blueberries for a fruity twist. They burst while baking and create little pockets of sweetness.
• Chocolate chips. Add ⅓ cup mini chocolate chips for an indulgent version. My kids go absolutely wild for this one.
• Dried cranberries or raisins. A chewy, tangy addition that works especially well in fall.
• Chai spice. Replace the cinnamon with 1 ½ teaspoons chai spice blend for a warmer, more complex flavor.
• Pumpkin. Swap the applesauce for pumpkin puree and add a pinch of nutmeg. Instant fall breakfast.
• Banana. Mash one ripe banana and fold it into the wet ingredients for extra sweetness and moisture.

How to Serve

This baked oatmeal is delicious straight from the oven, but it's also great at room temperature or reheated.

Warm a slice and pour a little milk over the top, like cereal. That's my go-to.

A dollop of Greek yogurt and a drizzle of maple syrup makes it feel a little more special.

You can also top it with nut butter for extra protein, or fresh fruit for brightness.

How can you go wrong with a breakfast that works warm, cold, or at room temp?

How to Store and Reheat

This is one of the most meal-prep-friendly breakfasts you can make.

• Room temperature. Covered on the counter for up to 2 days.
• Refrigerator. Store in an airtight container for up to 5 days. This is the best option for weekly meal prep.
• Freezer. Wrap individual squares in plastic wrap and freeze for up to 3 months. Thaw in the fridge overnight or on the counter for a couple hours.
• Reheating. Microwave a slice for 30 to 60 seconds until warmed through. You can also reheat in the oven at 350°F for 8 to 10 minutes.
