Step 1

For the filling: Preheat the oven to 375°. Stir together the sliced peaches, granulated sugar, lemon juice, vanilla, cinnamon, and kosher salt in a medium bowl. Pour the mixture into a 9-inch deep-dish pie plate or an 8-by-8-inch baking dish.

Step 2

For the topping: Stir together the flour, brown sugar, granulated sugar, and cinnamon in the same bowl. Add the melted butter and stir until the mixture is crumbly. Sprinkle the topping over the peach mixture.

Step 3

Bake until golden brown and bubbly, about 40 minutes. Serve with vanilla ice cream, if you like.
