Ingredients List
- 6 large ripe peaches, peeled, pitted, and sliced
- 1/4 cup granulated sugar
- 1 tablespoon cornstarch
- 1 teaspoon vanilla extract
- 1/2 teaspoon ground cinnamon
- 1 cup old-fashioned rolled oats
- 1/2 cup all-purpose flour
- 1/2 cup brown sugar, packed
- 1/2 teaspoon ground cinnamon (for topping)

- 1/2 cup unsalted butter, melted
Fresh peaches are the star of this recipe, offering natural sweetness and juiciness that pairs beautifully with the rich, buttery crisp topping. Old-fashioned rolled oats provide a hearty texture and crunch that elevates the dish.
Step-by-Step Instructions
- Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish lightly with butter or nonstick spray to prevent sticking.
- In a large mixing bowl, combine the sliced peaches, granulated sugar, cornstarch, vanilla extract, and ground cinnamon. Toss until the peaches are evenly coated, ensuring the cornstarch is well distributed for a thickened filling.
- Transfer the peach mixture to the prepared baking dish and spread evenly to cover the bottom.
- In another mixing bowl, stir together the rolled oats, flour, brown sugar, ground cinnamon, and salt to create the crisp topping.
- Pour the melted butter into the oat mixture and stir until fully combined and crumbly. The butter binds the dry ingredients, creating a crunchier texture when baked.
- Sprinkle the cinnamon-oat topping evenly over the peach mixture, ensuring coverage for a uniform bake.
- Bake in the preheated oven for 40-45 minutes, or until the topping is golden brown and the peaches are bubbling. Observe closely during the last 5 minutes to avoid overbrowning.
- Remove from the oven and let it cool for 10 minutes before serving. Serve warm, optionally topped with a scoop of vanilla ice cream or dollops of whipped cream for added indulgence.

Common Questions
- Can I use frozen peaches? Yes, thaw them completely and drain excess water before using to maintain the texture of the crisp.
- What’s the best way to peel peaches? Blanching them in hot water for 30 seconds and transferring to ice water helps loosen the skins for easy peeling.
- Can I make this gluten-free? Substitute all-purpose flour with an equal amount of almond flour or a gluten-free flour blend for similar results.
The Origins of Peach Crisp
Peach crisp belongs to a family of fruit-based desserts that date back centuries, rooted in using seasonal produce and simple pantry staples. While crisps gained popularity in America during the 20th century, peaches have been featured prominently in desserts for their natural sweetness and vibrant flavor.
The addition of oats to the topping distinguishes crisps from their counterparts like cobblers, adding a delightful crunch that has made them a staple at backyard barbecues and family dinners.
Storage and Reheating Tips
To store leftover peach crisp, cover the dish tightly with plastic wrap or transfer to an airtight container. Refrigerate for up to 3 days to maintain freshness and flavor.

For longer storage, freeze the crisp in individual portions using freezer-safe containers. Thaw in the refrigerator overnight before reheating.
Reheat in a 350°F (175°C) oven for 10-15 minutes to revive the crisp topping and warm the filling. Avoid microwaving as it may soften the crumb topping.
