How to Make Baked Oatmeal Recipe
Step 1: Preheat and Prep the Pan
Start by preheating your oven to 350°F (175°C). This ensures an even, golden bake from edge to center. Lightly grease an 8×8-inch or 9×9-inch baking dish with nonstick spray or a little oil, so your oatmeal squares slip out easily when it’s time to serve.
Step 2: Whisk the Wet Ingredients
In a large mixing bowl, mash your ripe banana or add the applesauce, then whisk in the maple syrup (or honey), eggs, milk, and that dreamy vanilla extract. This blend sets the stage for moist, gently sweet baked oats and smells absolutely heavenly as you mix.
Step 3: Stir in the Dry Ingredients
Add your rolled oats, baking powder, cinnamon, and salt straight into your wet mixture. Stir until just combined—no over-mixing! This is where the wholesome, cozy character of your Baked Oatmeal Recipe starts to come together.
Step 4: Fold in Your Favorite Mix-Ins
If you’re feeling creative, now’s the time to fold in a generous handful of chopped nuts, fresh or frozen berries, or even a sprinkle of chocolate chips. This personal touch makes the recipe truly yours—and it’s a great way to use up what you already have in the kitchen.
Step 5: Bake to Golden Perfection
Pour the oat mixture into your prepared dish and spread it out evenly. Pop it in the oven for 35 to 40 minutes. You’ll know it’s ready when the top is set and lightly golden, and your kitchen smells like a bakery! Let it cool for a few minutes before diving in for clean, satisfying slices.
How to Serve Baked Oatmeal Recipe

Garnishes
Once your Baked Oatmeal Recipe is out of the oven, let’s make it even more irresistible! Top each serving with a drizzle of warm maple syrup, a dollop of creamy yogurt, a handful of fresh berries, or a scattering of toasted nuts. These toppings add color, crunch, and an extra spark of flavor that makes your breakfast unforgettable.
Side Dishes
Pair your warm oatmeal squares with a crisp fruit salad, velvety scrambled eggs, or your favorite smoothie for a complete and satisfying meal. A steaming mug of coffee or herbal tea on the side also makes this breakfast feel extra special and comforting.
Creative Ways to Present
You can make individual portions using muffin trays for easy grab-and-go breakfasts, stack thick slices with layers of yogurt and fruit parfait-style, or cut the oatmeal into fun shapes for little ones. Embracing playful presentations makes your Baked Oatmeal Recipe experience even more delightful!
Make Ahead and Storage
Storing Leftovers
Any leftover Baked Oatmeal Recipe can be covered and kept in the fridge for up to five days. It holds its shape beautifully and makes breakfast time a breeze throughout the week—just grab a square, reheat, and go!
Freezing
To freeze, let the oatmeal cool completely, then slice it into portions and wrap individually or layer between parchment paper in an airtight container. It freezes well for up to three months, ready to thaw overnight for fast mornings.
Reheating
To enjoy your oatmeal bake hot and fresh, just pop a square in the microwave for about 30 seconds to a minute. If you like your oats extra creamy, add a splash of milk before reheating to keep things moist and tender.
