Step 1

Preheat the oven to 350°F (177°C). Lightly grease an 8 or 9-inch baking dish (circle or square). Set aside.

Step 2

Combine peaches with the flour, sugar, salt, and vanilla in a large bowl. Toss gently until combine. Spoon into prepared baking dish.

Step 3

Whisk the brown sugar, flour, oats, cinnamon, salt, and pecans together. Make sure to get out all those brown sugar lumps. Add the butter and stir with a rubber spatula or a wooden spoon to break up the butter until the mixture is crumbly. (A fork works for this too!) Evenly sprinkle topping over peaches.

Step 4

Bake for 40-45 minutes until the topping is golden brown and the peach juice is bubbling on the edges. Remove from the oven, place on a wire rack, and allow to cool slightly before serving. Serve warm, room temperature, or cold. Cover leftovers and store in the refrigerator for up to 5 days.
