Ingredients

Scale
  • 6 cups apples, peeled, cored, and sliced (about 900g) – Granny Smith, Honeycrisp, or Braeburn recommended
  • 1/4 cup granulated sugar (50g)
  • 1 tablespoon lemon juice (15ml)
  • 1 teaspoon ground cinnamon (3g)
  • 1/4 teaspoon ground nutmeg (1g, optional)
  • 1 tablespoon cornstarch (8g)
  • Pinch of salt
  • 3/4 cup all-purpose flour (95g)
  • 3/4 cup rolled oats (75g)
  • 1/2 cup brown sugar, packed (100g)
  • 1/4 cup granulated sugar (50g)
  • 1/2 teaspoon ground cinnamon (1.5g)
  • 1/4 teaspoon salt
  • 1/2 cup unsalted butter, cold and diced (113g)
  • Optional: 1/2 cup chopped pecans or walnuts (50g)
  • Optional: 1/4 cup dried cranberries or raisins (35g)

Instructions

  1. Preheat oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or non-stick spray.
  2. Peel, core, and slice apples into 1/2-inch pieces. Place in a large mixing bowl.
  3. Add granulated sugar, lemon juice, cinnamon, nutmeg (if using), cornstarch, and a pinch of salt to apples. Stir until coated and juices start to appear.
  4. Pour apple mixture into prepared baking dish, spreading evenly.
  5. In a separate bowl, combine flour, rolled oats, brown sugar, granulated sugar, cinnamon, and salt. Mix well.
  6. Add cold diced butter to the dry mixture. Use a pastry blender, two forks, or your fingers to cut butter into the mix until pea-sized clumps form.
  7. Stir in chopped nuts and/or dried fruit if desired.
  8. Sprinkle oat crumble topping evenly over the apple mixture.
  9. Bake for 40-45 minutes, until topping is golden brown and apples are bubbling at the edges. If topping browns too fast, loosely cover with foil for the last 10 minutes.
  10. Let cool for 15-20 minutes before serving to allow juices to thicken.
  11. Serve warm, optionally topped with vanilla ice cream or whipped cream.

Notes

Mix tart and sweet apples for best flavor and texture. Use cold butter for a crisp topping. For gluten-free, use almond flour and certified gluten-free oats. For vegan, use plant-based butter. Optional add-ins like nuts or dried fruit add extra crunch and flavor. Serve warm with ice cream or whipped cream. Leftovers keep well refrigerated for up to 4 days and can be reheated.
