Prepare the filling
- Preheat the oven to 375°F. Slice peaches into 1/2-inch wedges and place in a large bowl; add 1/3 cup granulated sugar, 2 tablespoons brown sugar, 1 tablespoon lemon juice, 2 tablespoons cornstarch, 1 tablespoon instant tapioca, 1/2 teaspoon cinnamon, and 1/8 teaspoon salt and toss gently until glossy.
Make the topping
- Brown 6 tablespoons unsalted butter in a small saucepan over medium heat until fragrant and nutty, about 3 to 4 minutes, then pour most of it into a bowl and reserve 1 tablespoon in the pan if toasting nuts; in a medium bowl, combine 1 1/2 cups flour, 3/4 cup brown sugar, 1/2 teaspoon baking powder, 1/4 teaspoon salt, and 3/4 cup chopped nuts, then stir in the warm browned butter to form clumps.
Pre-bake and assemble
- Spread the crumb topping on a rimmed baking sheet and bake at 375°F for 8 minutes; transfer the peach filling to a buttered 9×13-inch dish, scrape any juices into the dish, then crumble the partially baked topping evenly over the peaches.
Bake and rest
- Bake the assembled crisp at 375°F for 30 to 35 minutes until the topping is golden and the filling bubbles at the edges; let rest at least 20 minutes before serving to let the filling thicken.
Notes
Use slightly firm ripe peaches for the best texture; browning the butter warm helps clusters form. If using frozen peaches, thaw and drain before mixing and reduce sugar by 1 tablespoon. To re-crisp leftovers, warm single servings at 350°F for 10–12 minutes.
