Ingredients

Scale
  • 6 medium apples (about 2 lbs / 900g), peeled and sliced (mix of Granny Smith and Honeycrisp recommended)
  • 1/4 cup (50g) granulated sugar
  • 2 tablespoons (25g) light brown sugar, packed
  • 2 tablespoons (16g) all-purpose flour
  • 1 tablespoon (15ml) fresh lemon juice
  • 1 1/2 teaspoons ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1/4 teaspoon salt
  • 1 cup (80g) old-fashioned rolled oats
  • 3/4 cup (90g) all-purpose flour
  • 1/2 cup (100g) light brown sugar, packed
  • 1/4 cup (50g) granulated sugar
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 1/2 cup (113g) unsalted butter, cold and cut into small cubes

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or non-stick spray.
  2. Peel, core, and slice the apples into 1/4-inch thick pieces (about 6 cups).
  3. In a large bowl, combine the sliced apples, 1/4 cup granulated sugar, 2 tablespoons brown sugar, 2 tablespoons flour, lemon juice, 1 1/2 teaspoons cinnamon, nutmeg, and 1/4 teaspoon salt. Toss to coat evenly. Let sit for 5 minutes.
  4. In a medium bowl, whisk together the oats, 3/4 cup flour, 1/2 cup brown sugar, 1/4 cup granulated sugar, 1 teaspoon cinnamon, and 1/4 teaspoon salt. Add the cold butter cubes. Use a pastry cutter or your fingertips to work the butter into the dry ingredients until the mixture resembles coarse sand with some pea-sized clumps.
  5. Pour the apple mixture into the prepared baking dish and spread evenly. Sprinkle the oat crumble topping evenly over the apples without pressing down.
  6. Place the dish on a baking sheet. Bake for 40-45 minutes, until the filling is bubbly and the topping is golden brown. If the topping browns too quickly, loosely tent with foil for the last 10 minutes.
  7. Let the crisp cool on a wire rack for at least 15 minutes before serving to allow the filling to set.

Notes

For best results, use a mix of apple varieties like Granny Smith and Honeycrisp. Keep the butter cold for a crunchy topping. Let the crisp cool for at least 15 minutes before serving to prevent a runny filling. To make ahead, assemble without baking, cover, and refrigerate up to 24 hours; bake straight from the fridge, adding 10 minutes to the baking time.
