Ingredients

Scale
  • 6 medium apples, peeled, cored, and sliced (Honeycrisp or Granny Smith recommended)
  • 1/4 cup granulated sugar
  • 2 tablespoons brown sugar, packed
  • 1 tablespoon lemon juice
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1/4 teaspoon salt
  • 1 tablespoon cornstarch
  • 1/2 cup unsalted butter
  • 1 cup old-fashioned rolled oats
  • 3/4 cup all-purpose flour
  • 1/2 cup brown sugar, packed
  • 1/4 cup granulated sugar
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 1/2 cup chopped pecans or walnuts (optional)

Instructions

  1. Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or non-stick spray.
  2. Make the brown butter: Place 1/2 cup unsalted butter in a large skillet or saucepan over medium heat. Melt completely, then swirl occasionally. After 3-4 minutes, the butter will foam and bubble. Continue until golden brown specks form and it smells nutty (about 5-7 minutes total). Remove from heat immediately and pour into a heat-safe bowl to stop cooking.
  3. Prepare the apple filling: In a large bowl, toss the sliced apples with 1/4 cup granulated sugar, 2 tablespoons brown sugar, 1 tablespoon lemon juice, 1 teaspoon cinnamon, 1/4 teaspoon nutmeg, 1/4 teaspoon salt, and 1 tablespoon cornstarch. Let sit for 5 minutes.
  4. Make the oat crumble: In a medium bowl, combine 1 cup rolled oats, 3/4 cup flour, 1/2 cup brown sugar, 1/4 cup granulated sugar, 1 teaspoon cinnamon, and 1/4 teaspoon salt. Pour the browned butter over the dry ingredients and stir until the mixture resembles wet sand with some larger clumps. Fold in nuts if using.
  5. Assemble the crisp: Spread the apple mixture evenly in the prepared baking dish. Sprinkle the oat crumble over the top in an even layer. Do not press down.
  6. Bake for 35-40 minutes, until the filling is bubbly and the topping is golden brown. If the top browns too quickly, tent with foil after 25 minutes.
  7. Cool on a wire rack for at least 15 minutes before serving. Serve warm, preferably with vanilla ice cream or whipped cream.

Notes

Let the crisp rest for at least 15 minutes after baking to allow the filling to set. For best results, use a mix of apple varieties like Honeycrisp and Granny Smith. The brown butter can burn quickly, so watch it carefully. The crisp can be assembled up to 24 hours in advance and refrigerated; add 10 minutes to the baking time if starting from cold.
