Ingredients

Scale
  • 1 cup (226g) unsalted butter
  • 1 cup (120g) all-purpose flour
  • 1.5 cups (150g) old-fashioned rolled oats
  • 0.5 cup (100g) granulated sugar
  • 0.5 cup (115g) packed brown sugar
  • 2 teaspoons ground cinnamon
  • 0.5 teaspoon nutmeg
  • 0.5 teaspoon apple pie spice (optional)
  • 56 large Granny Smith apples, peeled, cored, and sliced
  • 1 tablespoon lemon juice
  • 1 tablespoon cornstarch
  • Flaky sea salt for finishing

Instructions

  1. Preheat oven to 375°F (190°C).
  2. Peel, core, and slice apples into 1/4-inch thick wedges. Place in a large bowl and toss with lemon juice and cornstarch. Let sit for 10 minutes.
  3. Melt butter in a heavy-bottomed saucepan over medium heat. Stir constantly until the foam subsides and the butter turns amber with a nutty aroma (about 5-7 minutes). Remove from heat and pour into a heatproof bowl.
  4. In a large mixing bowl, combine flour, oats, granulated sugar, brown sugar, cinnamon, nutmeg, and apple pie spice.
  5. Pour the warm brown butter over the dry ingredients. Mix with a pastry cutter or fingers until the mixture resembles coarse sand with some larger clumps.
  6. Spread the tossed apple slices evenly into a greased 9×13 inch baking dish.
  7. Sprinkle the oat streusel mixture over the apples, covering them completely.
  8. Bake for 45-50 minutes, or until the topping is golden brown and juices are bubbling. If the top browns too quickly, cover loosely with foil for the last 10 minutes.
  9. Remove from oven and sprinkle with flaky sea salt.
  10. Let cool for at least 15 minutes before serving to allow juices to set.

Notes

For a gluten-free version, swap all-purpose flour for a 1-to-1 gluten-free baking blend and ensure oats are certified gluten-free. If using softer apples like Fuji or Gala, add a bit more cornstarch. The topping may lose crispness in the fridge; reheat in the oven at 350°F for 10 minutes to restore texture. Do not microwave as it makes oats soggy.
