Bake Prep
- Preheat oven to 350°F (175°C). Choose a baking rack placement that lets the dish bake evenly.
- Butter a 9×13-inch baking dish. Coat the bottom and sides so the crisp releases easily.
Make the Peach Filling
- In a large bowl, combine fresh peaches, granulated sugar, light brown sugar, cornstarch, lemon juice, vanilla extract, ground cinnamon, ground nutmeg, and salt. Stir until the peaches look evenly coated and glossy.
- Transfer the peach mixture to the baking dish. Spread into an even layer so the filling bubbles throughout.
Make the Crisp Topping
- In another bowl, combine old-fashioned rolled oats, all-purpose flour, light brown sugar, ground cinnamon, and salt. Toss until no large dry clumps remain.
- Stir in the melted unsalted butter until crumbly. Rub any bigger bits together so the topping forms coarse crumbs.
- Fold in chopped pecans if using. Keep the pecans distributed so each bite has crunch.
- Sprinkle the topping evenly over the peaches. Cover the surface fully for a golden, crisp top.
Bake, Cool, and Serve
- Bake for 40–45 minutes at 350°F (175°C), until the topping is golden brown and the filling is bubbling. Look for thick bubbling at the edges and crisp-looking crumbs on top.
- Cool for 10 minutes. This helps the filling set slightly before serving.
- Serve warm with vanilla ice cream or whipped cream and fresh mint. Add mint last for a fresh finish.
Notes
For juiciest results, use ripe peaches and let the filling sit 5 minutes after mixing so cornstarch starts to thicken. Store leftovers covered in the refrigerator up to 4 days; rewarm in the oven at 325°F until heated through. Freezing is not recommended because the crumb topping can soften. For a lighter swap, use half the butter in the topping with an equal amount of unsweetened applesauce for a less rich crisp.
