Ingredients You’ll Need

Gathering just the right ingredients is key to making this 1 Bowl Baked Oatmeal shine, and you’ll find that each component plays an essential role. From the creamy milk that creates the perfect custard-like softness, to the fresh or frozen berries that bring a pop of color and natural sweetness, every ingredient contributes a touch of love to this cozy dish.

• 1 and 3/4 cups milk (dairy or nondairy): Creates a creamy texture and helps bind the oats together.
• 2 large eggs: Adds richness and structure so the oatmeal sets perfectly.
• 1/2 cup pure maple syrup: Brings just the right natural sweetness to make every bite irresistible.
• 1/4 cup unsalted butter, melted and slightly cooled: Inspires a rich, buttery depth that enhances flavor.
• 1/4 cup unsweetened applesauce or mashed banana: Adds moisture and natural sweetness, keeping the oatmeal soft.
• 3 cups old-fashioned whole rolled oats: The hearty base that gives structure and heartiness.
• 1 teaspoon baking powder: Gives a gentle lift, making the baked oatmeal tender.
• 1 teaspoon ground cinnamon: Infuses warmth and cozy spice into every bite.
• 1 teaspoon pure vanilla extract: Elevates flavor with sweet, aromatic notes.
• 1/4 teaspoon salt: Balances sweetness and enhances overall flavor.
• 1 and 1/2 cups fresh or frozen mixed berries (do not thaw): Bursts of juicy fruitiness that add vibrant color and tartness.
• Optional toppings: 1/2 cup chopped walnuts or pecans: For added crunch and a nutty contrast.

How to Make 1 Bowl Baked Oatmeal

Step 1: Prepare Your Baking Pan and Oven

Start by positioning your oven rack in the lower third and preheating it to 350°F (177°C). Grease a 9×9 inch or 11×7 inch baking dish with nonstick spray to ensure your oatmeal doesn’t stick and bakes evenly. This step might seem small, but it sets the stage for a perfectly cooked, easy-to-remove breakfast.

Step 2: Mix It All Together in One Bowl

Here’s where the magic happens: whisk your milk, eggs, maple syrup, melted butter, and applesauce (or banana) right in a large bowl until smooth and combined. Add the oats, baking powder, cinnamon, vanilla, salt, and berries straight into the same bowl and give everything a gentle stir. That’s the joy of the 1 Bowl Baked Oatmeal — no mess and maximum convenience!

Step 3: Pour and Top

Pour your oatmeal mixture into the prepared baking pan, spreading it out evenly. If you love the crunch of nuts, sprinkle chopped walnuts or pecans on top or gently fold them into the batter before baking for extra texture contrast.

Step 4: Bake Until Almost Set

Bake for about 35 minutes until the edges are firm and the center looks almost set but still soft to the touch. This ensures you get that perfect creamy texture inside with baked golden edges. If you prefer it more solid and drier, just bake a few minutes longer. Either way, you’re in for a deliciously satisfying breakfast.

Step 5: Cool and Serve

Allow your 1 Bowl Baked Oatmeal to cool for about 5 minutes before slicing or scooping. This brief wait lets it firm up just enough for perfect portions and makes it easier to enjoy with your favorite toppings or sides.

How to Serve 1 Bowl Baked Oatmeal

Garnishes

Once you’ve got your baked oatmeal out of the oven, freshening it up with garnishes can turn it into a breakfast celebration. A dollop of Greek yogurt or a splash of cream perfectly balances the gentle sweetness and adds wonderful creaminess. Don’t forget a sprinkle of extra cinnamon, drizzled honey, or a handful of fresh berries to brighten each bite.

Side Dishes

Pair your 1 Bowl Baked Oatmeal with freshly brewed coffee or a warm cup of chai tea for a comforting morning meal. For something heartier, crispy bacon or scrambled eggs provide a savory counterpoint that rounds out the breakfast beautifully.

Creative Ways to Present

Want to impress like a pro? Serve baked oatmeal in individual ramekins for a charming personal touch. You can also layer slices with yogurt and fruit parfait-style in a clear glass to show off those colorful berries nestled among the oats. It’s a feast for both eyes and palate.

Make Ahead and Storage

Storing Leftovers

One of the best things about 1 Bowl Baked Oatmeal is how well it keeps. After it cools, cover tightly and store leftovers in the refrigerator for up to a week. It makes for an easy grab-and-go breakfast or satisfying snack anytime.

Freezing

You can also freeze individual portions wrapped well in plastic wrap and foil or stored in airtight containers. Frozen baked oatmeal will keep for up to 2 months, so you’ll have a ready-made healthy breakfast waiting for busy mornings or unexpected guests.

Reheating

To reheat, pop a portion in the microwave for about 45-60 seconds until warmed through, or heat it gently in the oven covered with foil to maintain moisture. A quick warming brings back that freshly baked feeling and delicious aroma every time.

FAQs

Can I use rolled oats instead of quick oats?

This recipe is best with old-fashioned whole rolled oats, which provide the ideal texture and chew after baking. Quick oats tend to become mushy and won’t hold their shape as well.

What can I substitute for maple syrup?

If you don’t have maple syrup, honey or agave nectar are tasty alternatives that maintain the natural sweetness, though maple syrup has a unique depth that pairs beautifully with the cinnamon and berries.

Can I make this vegan?

Absolutely! Use a plant-based milk, replace eggs with flax or chia egg alternatives, and swap butter for coconut oil or vegan margarine to keep it dairy-free and still delicious.

Is it possible to add other fruits?

Definitely. Feel free to experiment with apples, pears, peaches, or even chopped dried fruits like cranberries or raisins. Just keep an eye on moisture content to maintain the perfect texture.

How do I know when the baked oatmeal is done?

Look for puffed, golden edges and a center that’s mostly set but still a bit soft. It will firm up more as it cools, giving you that tender, creamy consistency we all love in baked oatmeal.

Final Thoughts

There’s something genuinely wonderful about the simplicity and soul-warming goodness of this 1 Bowl Baked Oatmeal. It’s perfect for busy mornings when you want something quick but nourishing, or leisurely weekends when you want breakfast to feel like a special occasion.
