Ingredients

Scale
  • 6 cups apples, peeled and sliced (about 6 medium apples; mix of Granny Smith and Honeycrisp recommended)
  • 1/4 cup granulated sugar (adjust based on apple sweetness)
  • 2 tablespoons brown sugar
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1 teaspoon fresh lemon juice
  • 1 tablespoon all-purpose flour
  • 1 cup old-fashioned rolled oats
  • 3/4 cup all-purpose flour
  • 1/2 cup brown sugar, packed
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 1/2 cup unsalted butter, cold and cubed

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease your baking dish with butter or non-stick spray.
  2. In a large bowl, combine the sliced apples with granulated sugar, brown sugar, cinnamon, nutmeg, lemon juice, and flour. Toss gently until the apples are evenly coated and aromatic (about 2-3 minutes).
  3. Transfer the apple mixture into your prepared baking dish, spreading it evenly.
  4. In a separate bowl, mix together the rolled oats, all-purpose flour, brown sugar, cinnamon, and salt. Add the cold, cubed butter.
  5. Cut the butter into the dry ingredients using a pastry cutter or your fingers until the mixture resembles coarse crumbs with some pea-sized pieces.
  6. Sprinkle the streusel topping evenly over the apples, covering the filling completely.
  7. Bake in the preheated oven for 40-45 minutes, or until the topping is golden brown and the apple filling is bubbly around the edges.
  8. Cool slightly on a wire rack for about 10 minutes before serving.

Notes

Keep the butter cold when mixing the streusel to ensure a crisp topping. If the topping browns too quickly, tent with foil halfway through baking. For a softer topping, add a splash of heavy cream or milk before baking. Peeling apples is recommended to avoid chewy skin. You can prepare the crumble ahead and refrigerate or freeze before baking.
