Prep Time 20 minutes
Cook Time 1 hour
Servings 8 servings

Ingredients

For the Topping

  • ¾ cup flour
  • ½ cup packed light or dark brown sugar
  • 1 teaspoon ground cinnamon
  • ¼ teaspoon salt
  • 1 cup quick cook or old-fashioned oats
  • ½ cup butter, melted (4 ounces)

For the Filling

  • 8 large apples about 5 pounds, peeled and sliced
  • Zest and juice of one lemon
  • ¼ cup packed light or dark brown sugar plus more as needed
  • 1 teaspoon ground cinnamon
  • ¼ teaspoon salt
  • ¼ cup flour

Instructions

  1. Preheat oven to 350° F (177 °C). Lightly grease a 9x13-inch baking pan with softened butter.

  2. Prepare the Topping. Whisk together flour, brown sugar, cinnamon, and salt. Add the oats and stir to combine. Stir in the melted butter until there are no spots of dry topping in the bowl. Set the topping aside.

  3. Prepare the Filling. Stir together the apple slices, lemon zest and juice. Add the brown sugar, cinnamon, and salt. Taste. Add more sugar if needed. Add the flour and stir until all the apple slices are evenly coated.

  4. Spread the apples into an even layer in the prepared pan. Sprinkle the topping evenly over the apple slices.
  5. Bake until the filling bubbles, about an hour minutes. Remove pan from the oven. Allow apple crisp to cool for about 15 minutes before serving.
  6. Store leftover apple crisp covered in the refrigerator for up to four days. Reheat before serving in the microwave on low heat for about 30 seconds.
