Ingredients

Scale
  • 6 medium apples (about 2 pounds / 900 grams), peeled, cored, and sliced
  • ½ cup (100 grams) brown sugar, packed
  • 1 teaspoon ground cinnamon
  • 1 tablespoon freshly squeezed lemon juice
  • 1 cup (90 grams) old-fashioned rolled oats
  • ¾ cup (90 grams) all-purpose flour
  • ½ cup (115 grams) unsalted butter, cold and cubed
  • A pinch of salt
  • Vanilla ice cream, for serving

Instructions

  1. Preheat your oven to 350°F (175°C).
  2. Peel, core, and slice about 6 medium apples into roughly ¼-inch (0.6 cm) thick slices. Toss them in a large bowl with ½ cup (100 grams) brown sugar, 1 teaspoon cinnamon, and 1 tablespoon freshly squeezed lemon juice.
  3. Transfer the apple mixture to your cast iron skillet and spread it out evenly without packing it down.
  4. In a separate bowl, combine 1 cup (90 grams) old-fashioned rolled oats, ¾ cup (90 grams) all-purpose flour, a pinch of salt, and another ½ cup (100 grams) brown sugar. Cut in ½ cup (115 grams) cold, cubed unsalted butter using a pastry cutter or fork until the mixture resembles coarse crumbs.
  5. Sprinkle the oat crumble evenly over the apples.
  6. Bake for 40 to 45 minutes until the topping is golden brown and crisp, and the apples are bubbling around the edges. Tent loosely with foil halfway through if the topping browns too quickly.
  7. Remove from oven and let cool for 10 minutes before serving warm with a scoop of vanilla ice cream.

Notes

Use cold butter for a flaky crumble topping. Uniform apple slices ensure even cooking. If apples seem watery, toss with 1 tablespoon cornstarch before baking. Can swap all-purpose flour for almond flour for gluten-free option. Coconut oil can substitute butter for dairy-free version. Tent with foil if topping browns too fast. Let crisp rest 10 minutes before serving to thicken juices.
