Ingredients

Scale
  • 6 cups apples, peeled, cored, and sliced (about 6 medium apples)
  • 1/3 cup granulated sugar
  • 1/4 cup light brown sugar, packed
  • 2 tablespoons all-purpose flour
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1 tablespoon lemon juice
  • 1 teaspoon vanilla extract
  • 1/2 cup unsalted butter
  • 3/4 cup old-fashioned rolled oats
  • 1/2 cup all-purpose flour
  • 1/2 cup light brown sugar, packed
  • 1/4 teaspoon salt
  • 1/2 teaspoon cinnamon

Instructions

  1. Preheat your oven to 350°F (175°C). Position a rack in the center of the oven.
  2. Make the brown butter: Place the 1/2 cup unsalted butter in a light-colored saucepan over medium heat. Stir occasionally as it melts. The butter will foam and bubble. After about 5-7 minutes, when the foam subsides and brown specks form at the bottom and the butter smells nutty, remove from heat immediately and pour into a heatproof bowl to stop cooking.
  3. Prepare the apples: Peel, core, and slice apples into 1/4-inch thick slices. Toss in a large bowl with granulated sugar, brown sugar, flour, cinnamon, nutmeg, lemon juice, and vanilla extract until coated. Let sit for 5 minutes.
  4. Make the oat crumble: In a medium bowl, whisk together oats, flour, brown sugar, salt, and cinnamon. Pour the slightly cooled brown butter over the dry ingredients and stir with a fork until the mixture looks like wet sand with some larger clumps. Do not overmix.
  5. Assemble the crisp: Spread the apple mixture evenly in a 9×13-inch baking dish. Sprinkle the oat crumble over the top in an even layer. Do not press it down.
  6. Bake: Place the dish on a baking sheet. Bake for 40-45 minutes, or until the filling is bubbly around the edges and the crumble is deep golden brown. If the crumble browns too quickly, tent loosely with foil for the last 10 minutes.
  7. Cool and serve: 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 tart and sweet apples (e.g., Granny Smith and Honeycrisp). Brown the butter in a light-colored pan to monitor color. Let the crisp cool for at least 15 minutes before serving to allow the filling to set. Leftovers keep in the refrigerator for up to 4 days.
