Peach Baked Oatmeal

This wholesome and hearty peach baked oatmeal is a great way to start your day during peach season! Our family has made a variety of baked oatmeal recipes over the years, and this version has been a huge hit with our family and friends. Packed with sweet and juicy fresh peaches, this easy breakfast recipe is ideal for lazy weekend mornings or to prep for breakfasts throughout the week.

As someone who’s been developing breakfast recipes for busy families for years, I understand the challenge of creating something that’s both nutritious while also being delicious enough to get everyone excited about it. I’ve tested countless variations of baked oatmeal recipes, experimenting with different fruit combinations, sweetness levels, and textures to find what works best for real families with real morning routines. This peach version stands out because it strikes that sweet spot between being hearty enough to keep you satisfied and having just the right amount of natural sweetness from the peaches.

What makes this recipe especially reliable is that it’s built on the foundation of our already proven baked oatmeal recipes that have been family favorites for years. I adapted the successful formula from our popular lemon blueberry baked oatmeal and chocolate chip baked oatmeal recipes to accommodate a peach flavor profile, so you can trust that the base recipe delivers consistent results. The ingredient list is straightforward with pantry staples you likely already have on hand, and the method is simple enough that even kids can help with the preparation. Whether you’re serving it fresh from the oven on a weekend morning or reheating individual portions throughout the week, this peach baked oatmeal delivers the same comforting, satisfying results our family has come to love.

Peach Baked Oatmeal Ingredients

• Salted butter. Butter adds moisture and a savory flavor to our bake.
• Eggs. The primary roll of the eggs is to help hold our oatmeal bake together, resulting in a dish that can be sliced like a cake. They also add a bit of protein too – yay!   
• Milk. Milk adds the moisture needed to soften our oats. My family uses skim, 2%, or whole dairy milk for this recipe (whatever we happen to have in the fridge). The higher the fat content, the more decadent it will be. If desired, you can use your favorite non-dairy milk too (I’d recommend oat milk).
• Brown sugar. Brown sugar is a common sweetener for oatmeal, and it’s often paired with peaches too! Brown sugar helps enhance the natural sweetness of the peaches, while also adding a caramelized note and more robust depth of flavor to the bake.
• Baking powder. Baking powder contributes to a lighter and fluffy texture.
• Vanilla extract. Vanilla extract adds both depth of flavor and richness to our bake.
• Cinnamon, ginger, and nutmeg. This combination of spices adds warmth and depth of flavor to our oatmeal, and nicely compliments the sweetness of the peaches.
• Salt. Just a little salt helps to enhance the flavors of the dish and balance the sweetness in this recipe. 
• Old-fashioned oats (aka rolled oats). For the best texture, use old fashioned rolled oats! I do not recommend subbing out the type of oats in this recipe as the texture and baking time could change drastically. You can learn more about why this is in my post on everything you need to know about oats.  
• Fresh peaches. There’s nothing better than fresh, in-season peaches. They’re sweet, and juicy, and taste like sunshine. This is an excellent use if you happen to have several going ripe (or beginning to go past ripe) at the same time… this happens to use a lot since my husband likes to grab a bushel of them at a time… if you know, you know.
• Cinnamon-Sugar topping. Through our recipe development, we found that adding a little sprinkle of cinnamon mixed with granulated sugar on top before baking added a nice, caramelized note and crunch to our baked oatmeal that was a delight.
• Optional toppings for serving. If desired, add a drizzle of maple syrup, a dollop of vanilla Greek yogurt (my favorite!), a splash of milk, chia seeds, and/or chopped nuts (like pecans, walnuts, or sliced almonds). You can also use our peach syrup to really amp up the peach flavor. Adding more fresh peach slices, or other fresh fruit, is a great choice too.

How to Make Baked Oatmeal with Peaches

Prep. Preheat your oven to 350°F and grease a square baking pan (either an 8×8 or a 9×9). Set aside. 

Mix the wet ingredients (the melted butter, brown sugar, eggs, milk, and vanilla extract) together in a large mixing bowl.

Slowly mix in the dry ingredients, starting with the baking powder, spices, and salt.

Add the dry old-fashioned oats to the bowl, stirring to combine.

Add the peaches, gently mixing them into the oat mixture.

Transfer the oatmeal mixture to the prepared pan, gently pressing it into an even layer.

Sprinkle the top with the cinnamon-sugar mixture.

Transfer to the preheated oven and bake until the center of the baked oatmeal looks almost set and the edges are golden brown.

Let the baked oatmeal cool for 5 minutes before serving. Then slice or spoon into serving bowls, adding desired toppings.  

Possible Dietary Restrictions?

This baked oatmeal recipe is vegetarian and gluten free as written, however, oats have a high likelihood of gluten contamination during processing. So if you’re serving this to someone with celiac, be sure to check the label and select rolled oats that are certified to be gluten free.

To make this into dairy free oatmeal bake, select a non-dairy milk (like unsweetened oat milk, almond milk, or soy milk) and replace the salted butter with oil (like canola oil, vegetable oil, or coconut oil) or a plant-based butter.

Storing this Peach Baked Oatmeal Recipe

Does Baked Oatmeal Need to be Refrigerated?

Yes, leftover baked oatmeal should be stored in the fridge tightly wrapped or in an airtight container. Doing so helps it last for up to 5 days. Be sure to let the oatmeal bake cool to room temperature before placing it in the fridge.

Can You Freeze Baked Oatmeal?

Yes, baked oatmeal is freezer-friendly and can be frozen for up to 3 months. To do so, simply wrap cooled, individual portions in plastic wrap and place them into a labeled freezer-safe zip top bag. When ready to enjoy, allow the frozen peach baked oatmeal to thaw in the fridge overnight before reheating. 

How to Reheat Baked Oatmeal

Reheat individual portions of the baked oatmeal in the microwave. Begin by heating your slice in short intervals (such as 30-second intervals) until your desired temperature has been reached. Once you’ve reheated one slice, you’ll have a better idea of how long your microwave needs to warm up your baked oatmeal.
