Ingredients

For this delicious Peach Baked Oatmeal, you’ll need:

• 2 cups old-fashioned rolled oats (not quick oats)
• 1/2 cup light brown sugar, packed
• 1 teaspoon baking powder
• 1 1/2 teaspoons ground cinnamon
• 1/4 teaspoon salt
• 1/4 teaspoon ground nutmeg
• 2 cups milk (dairy or plant-based)
• 2 large eggs
• 3 tablespoons unsalted butter, melted and slightly cooled
• 2 teaspoons pure vanilla extract
• 2 1/2 cups fresh peaches, diced (about 3-4 medium peaches)
• 1/2 cup chopped pecans or walnuts (optional)

The star ingredient here is undoubtedly the peaches. When in season, fresh peaches provide the best flavor and texture, though frozen (thawed and drained) work well in winter months. Use old-fashioned rolled oats rather than quick oats for the ideal texture in your baked peach oatmeal.

Pro Tips

Use the Right Oats: For the perfect Peach Baked Oatmeal, always choose old-fashioned rolled oats rather than quick-cooking or instant varieties. Quick oats will become too mushy when baked, while steel-cut oats won’t soften properly in this recipe. The rolled oats maintain their texture while still becoming tender during baking.

Perfect Peach Preparation: For the best flavor infusion, toss your diced peaches with a tablespoon of your brown sugar before adding them to the mixture. This helps draw out their juices and intensifies their natural sweetness. If using fresh peaches, leave the skin on for added texture and nutritional benefits—just be sure to wash them thoroughly.

Achieving the Ideal Texture: The secret to perfectly textured baked oatmeal with peaches lies in the ratio of liquid to oats and the baking time. Let the mixture rest for 5-10 minutes after combining wet and dry ingredients before baking. This allows the oats to begin absorbing the liquid. For a creamier result, add an extra 1/4 cup of milk; for a firmer, more sliceable texture, reduce the milk by the same amount.

Instructions

Step 1: Prepare Your Ingredients
Preheat your oven to 350°F (175°C) and grease an 8×8 inch baking dish. Wash, pit, and dice your peaches into 1/2-inch chunks. If your peaches aren’t quite ripe, you can toss them with an additional tablespoon of brown sugar to enhance their sweetness.

Step 2: Mix Dry Ingredients
In a large mixing bowl, combine the rolled oats, brown sugar, baking powder, cinnamon, salt, and nutmeg. Whisk together to ensure the spices are evenly distributed throughout the oat mixture. This ensures every bite of your Peach Baked Oatmeal will be perfectly flavored.

Step 3: Combine Wet Ingredients
In a separate bowl, whisk together the milk, eggs, melted butter, and vanilla extract until smooth and well combined. The eggs will help bind the oatmeal together, giving it a delightful custard-like quality once baked.

Step 4: Create Your Oatmeal Mixture
Pour the wet ingredients into the dry ingredients and stir until everything is thoroughly combined. Gently fold in about 2 cups of the diced peaches and half of the nuts (if using), reserving some of each for topping. Allow the mixture to sit for 5 minutes so the oats can begin absorbing the liquid.

Step 5: Assemble and Bake
Transfer the oatmeal mixture to your prepared baking dish, spreading it evenly. Top with the remaining peaches and nuts, arranging them attractively. Bake in the preheated oven for 40-45 minutes, or until the top is golden brown and the center is set but still slightly moist. Your kitchen will fill with the heavenly aroma of warm peaches and cinnamon!

Step 6: Serve and Enjoy
Allow your Peach Baked Oatmeal to cool for 10 minutes before serving. This resting period allows the oatmeal to set up properly and makes it easier to portion. Serve warm with a drizzle of maple syrup, a dollop of yogurt, or a splash of milk if desired.

Variations

Berry Peach Fusion: Transform your Peach Baked Oatmeal by incorporating mixed berries alongside the peaches. Replace half the peaches with blueberries, raspberries, or blackberries for a beautiful color contrast and additional antioxidants. The berries will burst during baking, creating vibrant pockets of flavor throughout the oatmeal.

Tropical Twist: Give your baked oatmeal a vacation-inspired makeover by adding 1/2 cup of shredded coconut to the oat mixture and replacing 1/2 cup of the milk with coconut milk. For extra tropical flair, include 1/2 cup of diced mango along with the peaches and top with toasted coconut flakes before serving.

Vegan Adaptation: Make this peach oatmeal bake completely plant-based by substituting the eggs with 2 tablespoons of ground flaxseed mixed with 6 tablespoons of water (let sit for 5 minutes before using). Replace the butter with melted coconut oil or vegan butter, and use your favorite plant-based milk. The result is equally delicious and suitable for those following a vegan diet.

Storage and Serving

Once cooled completely, store your Peach Baked Oatmeal in an airtight container in the refrigerator for up to 5 days. Individual portions can be wrapped separately for grab-and-go breakfasts throughout the week. For longer storage, freeze portions in freezer-safe containers for up to 3 months. Thaw overnight in the refrigerator before reheating.

For reheating, microwave individual portions for 60-90 seconds or until warmed through. To maintain the slightly crisp top texture, reheat in a 350°F oven for about 10 minutes. A toaster oven works beautifully for single servings.

Serve your baked peach oatmeal with a variety of toppings to keep it interesting throughout the week. Try a dollop of Greek yogurt and a drizzle of honey for added protein, a splash of warm milk for a traditional oatmeal feel, or a spoonful of almond butter for healthy fats that will keep you satisfied until lunch.

FAQs

Can I use canned peaches for this Peach Baked Oatmeal?
Yes, you can use canned peaches if fresh aren’t available. Choose peaches packed in juice rather than syrup, drain well, and reduce the added sugar by 2 tablespoons to account for the sweetness of the canned fruit.

Can I prepare this the night before and bake in the morning?
Absolutely! Prepare the mixture, cover, and refrigerate overnight. In the morning, let it sit at room temperature for 10 minutes while your oven preheats, then bake as directed. You may need to add 5 minutes to the baking time.

Is this recipe gluten-free?
This recipe can be gluten-free if you use certified gluten-free oats. Regular oats are naturally gluten-free, but may be processed in facilities that also handle wheat products.

Can I double this recipe for a larger crowd?
Yes, simply double all ingredients and use a 9×13 inch baking dish. The baking time may increase by 5-10 minutes, so check for doneness by ensuring the center is set.

How can I tell when my Peach Baked Oatmeal is done?
The oatmeal is done when the edges are golden brown, the top appears set, and a knife inserted in the center comes out mostly clean with just a bit of moisture. The center should be moist but not soupy.
