Step 1

Preheat the oven to 350°F (177°C). Lightly grease a deep-dish 9-inch pie dish, 9-inch square pan, 10-inch cast iron skillet, or any 2–2.5-quart baking dish. Set aside.

Step 2

Gently mix all of the filling ingredients together in a large bowl, then spread into the baking dish.

Step 3

Whisk the brown sugar, flour, cinnamon, and salt together in a medium bowl. Cut in the butter using a pastry cutter or forks until the mixture is crumbly. Fold in the oats and pecans. Sprinkle evenly over filling.

Step 4

Bake for 45–50 minutes until the topping is golden brown and the fruit juices are bubbling around the edges. Remove from the oven, place on a wire rack, and allow to cool for a few minutes before serving warm. You can also serve room temperature or cold.

Step 5

Cover leftovers and store in the refrigerator for up to 5 days.
