Ingredients

Scale
  • 6 medium apples (about 2 pounds or 900g), peeled, cored, and sliced into ¼-inch thick pieces (mix of Granny Smith and Honeycrisp recommended)
  • ¼ cup (50g) granulated sugar
  • 2 tablespoons (15g) all-purpose flour
  • 1 teaspoon ground cinnamon
  • ¼ teaspoon ground nutmeg (optional)
  • 1 tablespoon lemon juice
  • 1 cup (90g) old-fashioned rolled oats
  • ½ cup (60g) all-purpose flour
  • ½ cup (100g) packed brown sugar (light or dark)
  • ¼ cup (50g) granulated sugar
  • ½ teaspoon ground cinnamon
  • ¼ teaspoon salt
  • ½ cup (113g or 1 stick) unsalted butter, melted

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly butter an 8×8-inch baking dish.
  2. Peel, core, and slice the apples into ¼-inch thick half-moons. Place them in a medium mixing bowl.
  3. To the apples, add ¼ cup granulated sugar, 2 tablespoons flour, 1 teaspoon cinnamon, ¼ teaspoon nutmeg (if using), and 1 tablespoon lemon juice. Toss until all apple slices are coated. Let sit while you make the topping.
  4. In a small bowl, combine 1 cup rolled oats, ½ cup flour, ½ cup brown sugar, ¼ cup granulated sugar, ½ teaspoon cinnamon, and ¼ teaspoon salt. Stir with a fork to break up clumps. Pour in the melted butter and stir until the mixture is moistened and clumpy.
  5. Pour the apple mixture into the prepared baking dish and spread into an even layer. Sprinkle the oat topping evenly over the apples, using your fingers to drop clumps for texture.
  6. Place the dish on a baking sheet and bake for 40-45 minutes. If the topping browns too quickly, tent loosely with foil after 30 minutes. The crisp is done when the filling is bubbly and the apples are tender.
  7. Let the crisp cool on a wire rack for at least 15-20 minutes before serving. Serve warm, optionally with vanilla ice cream.

Notes

For extra crunch, place the crisp under the broiler for 1-2 minutes after baking. Let the apples macerate for 10-15 minutes after tossing with sugar and flour to prevent a watery filling. Use a mix of Granny Smith and Honeycrisp apples for the best texture and flavor. Bake on a sheet pan to catch any overflow.
