This peach oatmeal bake is one of those cozy, no-fuss desserts that feels like it came straight from an old Amish church cookbook. It’s just five ingredients and comes together in the time it takes to preheat your oven. You literally spoon canned sliced peaches and three simple pantry ingredients right over uncooked rolled oats in a baking pan, then let the oven do the rest. It’s perfect for busy weeknights, potlucks, or when you want something warm and comforting that everyone always comes back for seconds of.
Serve this peach oatmeal bake warm, scooped straight from the pan. It’s lovely on its own, but a dollop of whipped cream, a scoop of vanilla ice cream, or a spoonful of vanilla yogurt makes it extra special. For brunch, pair it with scrambled eggs and sausage or bacon for some protein. For dessert, a hot cup of coffee or tea balances the sweetness nicely. If you’re serving kids, let them sprinkle a few chopped nuts or extra cinnamon on top so they can “decorate” their own bowls.
Amish-Style 5-Ingredient Peach Oatmeal Bake
Servings: 6-8

Ingredients
2 cups old-fashioned rolled oats (uncooked)
2 cans (15 ounces each) sliced peaches in light syrup, undrained
1/2 cup packed brown sugar
1/4 cup unsalted butter, melted
1 teaspoon ground cinnamon
Directions
Preheat your oven to 350°F (175°C). Lightly grease a 9x13-inch baking pan with butter or cooking spray.
Spread the uncooked rolled oats evenly in the bottom of the prepared baking pan. You should see a thin, even layer of dry oats covering the whole surface.
In a medium bowl, stir together the brown sugar and ground cinnamon until no big clumps of sugar remain.
Open the canned sliced peaches and pour both cans, with all their light syrup, into the bowl with the brown sugar and cinnamon. Gently stir to coat the peaches and syrup with the sugar mixture.
Spoon the peach slices and the sweetened syrup evenly over the layer of uncooked rolled oats in the baking pan, making sure to cover the oats as much as possible. This should look like a rustic layer of peaches sitting on top of the dry oats.
Drizzle the melted butter evenly over the top of the peaches and oats, trying to cover as much of the surface as you can.
Place the pan on the middle rack of the preheated oven and bake for 30–35 minutes, or until the peaches are bubbling, the oats have absorbed most of the syrup, and the edges are lightly golden.
Remove from the oven and let the bake rest for about 10 minutes so it can set up a bit before scooping. Serve warm, straight from the pan.
Variations & Tips
For a little extra texture, you can sprinkle 1/4 cup of chopped pecans or walnuts over the top before baking, keeping in mind any nut allergies in your family. If you prefer it less sweet, reduce the brown sugar to 1/3 cup or use peaches canned in juice instead of light syrup. To make it feel more like breakfast than dessert, stir 1 teaspoon of vanilla extract into the peach mixture and serve with Greek yogurt instead of ice cream. For picky eaters, you can chop the peach slices into smaller pieces so they’re less noticeable, or add a small handful of mini chocolate chips over just part of the pan as a “treat corner.” If you need this to be dairy-free, swap the butter for an equal amount of melted coconut oil or a neutral vegetable oil. Food safety tips: Always make sure the bake is heated through and bubbling before serving, especially if your oven runs cool. Let the pan cool until it’s warm, not hot, before letting kids help serve themselves. Refrigerate leftovers within 2 hours of baking, cover tightly, and eat within 3–4 days. Reheat individual portions in the microwave until steaming hot, and discard if you notice any off smells or mold.
