Baked Oatmeal with Peaches Recipe

There’s something so comforting about the aroma of ripe peaches bubbling away in the oven, especially when it’s for breakfast. This baked oatmeal with peaches is one of my summer staples. It’s warm, nourishing, and full of flavor. I first made it on a whim with some overripe peaches from the farmers’ market, and it’s been a family favorite ever since. The oats bake up soft and cozy, soaking in all that peachy sweetness with just a touch of cinnamon.

What I love most about this baked oatmeal with peaches is how easy it is to pull together with simple ingredients you already have. It’s a no-fuss recipe that feels indulgent but is actually packed with goodness. Whether you’re planning a lazy weekend breakfast or looking for something you can reheat all week long, baked oatmeal with peaches always hits the spot.

Why This Baked Oatmeal with Peaches Is Perfect for Summer

Summer peaches are pure magic, and this baked oatmeal with peaches is one of my favorite ways to enjoy them while they’re at their juiciest. As the oatmeal bakes, the peaches turn soft and jammy, their natural sweetness caramelizing into golden pockets of flavor that melt right into the oats. I love making this baked oatmeal with peaches ahead of time so breakfast is ready to go on even the busiest mornings.

It’s hearty, comforting, and feeds everyone, from my picky toddler to my always-hungry teens. The texture lands somewhere between a warm crumble and a classic casserole, which means even folks who usually skip oatmeal come back for seconds. Served with fresh berries or a scoop of yogurt, baked oatmeal with peaches is a feel-good summer breakfast that never gets old.

Ingredients

Dry Ingredients:

• Old-fashioned rolled oats (use certified gluten-free oats if needed)
• Brown sugar (or coconut sugar for refined-sugar-free option)
• Baking powder
• Ground cinnamon
• Salt
• Ground nutmeg (optional, but adds warmth)

Wet Ingredients:

• Milk of choice (whole milk, almond milk, or oat milk work great)
• Large egg, beaten
• Melted butter or coconut oil
• Vanilla extract
• Maple syrup (adjust to taste)

Fruit and Add-ins:

• Fresh peaches, diced (about 3-4 medium peaches)
• Chopped walnuts or pecans (optional)
• Mini chocolate chips (optional, for extra indulgence)

Smart Substitutions: Can't find fresh peaches? Frozen peaches work wonderfully – just thaw and drain excess liquid first. Canned peaches in juice (not syrup) are another great option. For a protein boost, add a scoop of vanilla protein powder and increase the liquid slightly. Those following a vegan diet can swap the egg for a flax egg and use plant-based milk and oil.

Instructions

Prepare and Mix Dry Ingredients

1. Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking dish with butter or cooking spray. This size works perfectly for feeding a family of 4-6 people. If you're cooking for fewer people, you can use an 8x8-inch dish and reduce the baking time by about 5 minutes.
2. In a large mixing bowl, whisk together the oats, brown sugar, baking powder, cinnamon, salt, and nutmeg. This step ensures even distribution of the leavening and spices throughout your baked oatmeal. The cinnamon pairs beautifully with the peaches, while the nutmeg adds a subtle warmth that makes this recipe feel extra special.

Combine Wet Ingredients and Mix Batter

1. In a separate bowl, whisk together the milk, beaten egg, melted butter, vanilla extract, and maple syrup. Make sure your butter isn't too hot, or it might cook the egg. Room temperature ingredients blend more easily, so pull your milk and egg from the fridge about 30 minutes before starting.
2. Pour the wet ingredients into the dry ingredients and stir until just combined. Don't overmix – a few lumps are perfectly fine.
3. Gently fold in the diced peaches and nuts if using. The peaches will release some juice as they bake, creating natural pockets of sweetness throughout the oatmeal.

Bake to Perfection

1. Pour the mixture into your prepared baking dish and spread it evenly with a spatula.
2. Bake for 35-40 minutes, or until the top is golden brown and the center is set. You'll know it's done when a toothpick inserted in the center comes out with just a few moist crumbs.
3. The edges should be slightly crispy while the center remains tender – this contrast in textures is what makes this baked oatmeal so special.

Cool and Serve

1. Let the baked oatmeal rest for about 10 minutes before serving. This allows it to set properly and makes it easier to cut into neat squares.
2. Serve warm with your favorite toppings: a drizzle of milk, a dollop of Greek yogurt, or even a small scoop of vanilla ice cream for a special treat.
3. Cut into 8-12 squares depending on your desired portion size – larger squares work great for hungry adults, while smaller portions are perfect for kids.

Pro Tips for the Best Baked Oatmeal with Peaches

Here's a game-changing tip: toss your diced peaches with a tablespoon of flour before folding them into the batter. This prevents them from sinking to the bottom and helps distribute them evenly throughout the bake. The flour also absorbs some of the peach juice, preventing the bottom from becoming soggy.

For extra flavor depth, try browning your butter before adding it to the wet ingredients. This creates a nutty, caramelized flavor that complements the peaches beautifully. Just let it cool slightly before mixing it in so it doesn't scramble the egg.

Health Benefits and Dietary Information

This healthy baked oatmeal is packed with fiber from the oats, which helps keep you full and satisfied all morning long. Oats contain beta-glucan, a type of soluble fiber that's been shown to help lower cholesterol levels and support heart health. The peaches provide vitamin C, potassium, and antioxidants that support immune function and skin health.

This Baked Oatmeal with Peaches recipe is naturally vegetarian and can easily be made vegan with simple substitutions. It's also naturally gluten-free when you use certified gluten-free oats. For those watching their sugar intake, the natural sweetness from the peaches means you can reduce the added sugars without sacrificing flavor.

Each serving provides approximately 250 calories, 8 grams of protein, and 5 grams of fiber. It's a balanced breakfast that provides sustained energy without the crash that comes from sugary cereals or pastries. The combination of complex carbohydrates, healthy fats, and protein makes this an ideal breakfast for active families.

Creative Variations and Substitutions

Peach Cobbler Oatmeal Variation

Add an extra ¼ cup of brown sugar and top with a crumbly mixture of oats, butter, and cinnamon before baking. This creates a cobbler-like topping that's absolutely irresistible.

Peaches and Cream Baked Oatmeal

Stir in ½ cup of cream cheese cubes before baking for an extra rich and creamy texture. The cream cheese melts into pockets of tanginess that balance the sweet peaches perfectly.

Tropical Twist

Replace the peaches with diced mango and add shredded coconut and macadamia nuts. This transforms the recipe into a tropical breakfast escape.

Apple Peach Combo

Use half peaches and half diced apples for a fall-inspired version. Add a pinch of ginger and cardamom for extra warmth.

Protein-Packed Version

Add a scoop of vanilla protein powder and an extra ¼ cup of liquid to create a high-protein breakfast that's perfect for athletes or anyone looking to increase their protein intake.

Essential Equipment for Success

A 9x13-inch baking dish is ideal for this Baked Oatmeal with Peaches recipe, but you can also use individual ramekins for portion control or a cast-iron skillet for a rustic presentation. A good mixing bowl set makes combining ingredients much easier, and a whisk helps create a smooth, lump-free batter.

If you're making this Baked Oatmeal with Peaches recipe regularly, consider investing in a digital kitchen scale for more consistent results. Measuring oats by weight rather than volume gives you better consistency from batch to batch. A sharp knife and cutting board are essential for cleanly dicing the peaches.

Storage and Make-Ahead Tips

This baked oatmeal with peaches stores beautifully in the refrigerator for up to 5 days in an airtight container. For best results, let it cool completely before storing. Individual portions reheat wonderfully in the microwave for 30-45 seconds, making it perfect for grab-and-go breakfast options.

For longer storage, this Baked Oatmeal with Peaches recipe freezes well for up to 3 months. Cut it into individual portions and wrap each piece in plastic wrap, then place in a freezer-safe container. Thaw overnight in the refrigerator and reheat in the microwave or oven.

You can also prepare this as a make-ahead breakfast by assembling everything the night before and baking it fresh in the morning. Just combine all ingredients, pour into your baking dish, cover with plastic wrap, and refrigerate overnight. In the morning, remove from the fridge while the oven preheats and bake as directed.
