The Best Peach Baked Oatmeal Recipe

Ingredients

See the recipe card below this post for more ingredients quantities

• 2 (15 oz.) cans sliced peaches (in their juice): The heart of this peach baked oatmeal. Using peaches in juice rather than syrup keeps the sweetness balanced, and the reserved juice becomes part of the liquid base that flavors everything.

• ½ cup brown sugar (divided): Half caramelizes under the peaches during baking, and the other half sweetens the oat layer. Brown sugar adds warm, molasses depth that white sugar just can't replicate.

• ½ teaspoon cinnamon (divided): Split between both layers so the spice runs through every bite from bottom to top.

• 8 tablespoon salted butter (divided): Diced and scattered through both layers, it melts into richness and helps the oat topping get that gorgeous crispy finish.

• ½ teaspoon vanilla or almond extract (divided): Vanilla deepens both layers with warmth. Almond extract gives a slightly nuttier, bakery-style note if you want to change things up.

• 3 cups old-fashioned or rolled oats: These hold their texture during baking so the topping stays hearty and satisfying, not mushy.

• 1 pinch salt: Even in a sweet dish, salt pulls everything together and keeps it from tasting flat.

• ½ cup heavy cream: Adds a custardy richness to the oat layer as it bakes.

• 2 large eggs (beaten): Help bind the oat mixture so it sets up cleanly instead of falling apart when you scoop it.

How to Make Peach Baked Oatmeal

Making this dish is genuinely easy. Here is a simple walkthrough of every step.

Preheat the oven: Set your oven rack to the middle position and preheat to 375 degrees F. A centered rack helps this peach baked oatmeal cook evenly from edge to edge.

Prepare the peaches: Drain both cans of peaches and save the juice in a measuring cup or bowl. Pour the drained peaches into an 8x8-inch baking dish and set six slices aside for the garnish. Sprinkle ¼ cup of the brown sugar and ¼ teaspoon of cinnamon over the top. Dice 4 tablespoon of the butter into small pieces and scatter them over the peaches, then add ¼ teaspoon of vanilla. Stir gently to combine, then spread back into an even layer.

Mix the dry oat base: In a large bowl, stir together the oats, remaining ¼ teaspoon of cinnamon, pinch of salt, and remaining ¼ cup of brown sugar until the spices and sugar coat the oats evenly.

Make the wet mixture: Measure out 1 cup of the reserved peach juice and whisk it together with the heavy cream, remaining ¼ teaspoon of vanilla, and beaten eggs until fully blended.

Combine and assemble: Pour the wet mixture into the bowl of oats and stir just until the oats are moistened. Don't over-mix. Spoon the oat mixture evenly over the peach layer in the baking dish and spread it out gently.

Add the butter topping and garnish: Dice the remaining 4 tablespoon of butter and scatter the pieces over the oat layer. Nestle the reserved peach slices on top. This step is what gives your peach baked oatmeal that beautiful caramelized top, so don't skip it.

Bake: Place the dish in the oven and bake for 45 minutes until the top is deep golden brown and you can see the edges bubbling slightly. The kitchen will smell incredible.

Rest and serve: Let the peach baked oatmeal cool for about 15 minutes before scooping. This helps it firm up so portions hold their shape. Serve as is or with a slow drizzle of cream over the top.

Substitutions and Swaps

This peach baked oatmeal is easy to adapt. Here are a few swaps that work beautifully.

• Fresh or frozen peaches can replace canned. If using frozen, thaw and drain them first, then use water or apple juice in place of the reserved peach juice. This frozen peach baked oatmeal version is just as delicious.

• Maple syrup or honey can stand in for the brown sugar. Use about 3 tablespoon per ¼ cup of sugar.

• Coconut cream works in place of heavy cream for a lighter option with a subtle tropical note.

• Almond extract instead of vanilla gives the whole dish a warm, bakery-style flavor that Emma swears by.

• Half-and-half can replace heavy cream for a slightly lighter finish.

Equipment You'll Need

• 8x8-inch baking dish (use a 13x9-inch for doubling the recipe)

• Large mixing bowl

• Measuring cups and spoons

• Knife for dicing butter

• Oven

Storage Tips

Refrigerator: Cover the baking dish or transfer leftovers to an airtight container. This peach baked oatmeal stays fresh in the fridge for up to 4 days.

Freezer: Portion into individual servings and freeze in freezer-safe containers for up to 2 months. Thaw overnight in the fridge before reheating.

Reheating: A few minutes in the microwave works great on busy mornings. For a crispier top, reheat individual portions in a 350 degree F oven for about 10 minutes.
