Ingredients

Scale
  • 6 medium apples (about 2 pounds), peeled, cored, and sliced thin (Granny Smith and Honeycrisp recommended)
  • 2 tablespoons granulated sugar
  • 2 tablespoons all-purpose flour
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg (optional)
  • 2 teaspoons fresh lemon juice
  • 1 teaspoon vanilla extract
  • 3/4 cup old-fashioned rolled oats
  • 3/4 cup all-purpose flour (or almond flour for gluten-free)
  • 1/2 cup packed brown sugar
  • 1/4 cup granulated sugar
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 1/2 cup unsalted butter, cold and diced
  • Optional: 1/2 cup chopped walnuts or pecans
  • Optional: 1/2 cup dried cranberries or raisins
  • Optional: 1 tablespoon ground flaxseed

Instructions

  1. Preheat oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or nonstick spray.
  2. Peel, core, and slice apples into 1/4-inch thick slices. Place in a large mixing bowl.
  3. Add granulated sugar, flour, cinnamon, nutmeg (if using), lemon juice, and vanilla extract to apples. Toss until evenly coated.
  4. Spread apple mixture evenly in the prepared baking dish.
  5. In a medium bowl, combine oats, flour, brown sugar, granulated sugar, cinnamon, and salt. Mix well.
  6. Add cold, diced butter to the oat mixture. Cut in butter using a pastry cutter, fork, or hands until crumbly and pea-sized clusters form.
  7. Stir in optional mix-ins (nuts, dried fruit, flaxseed) if desired.
  8. Sprinkle oat topping evenly over apples, leaving it loose for texture.
  9. Bake on center rack for 45–55 minutes, until topping is golden brown and filling is bubbling. Cover loosely with foil if topping browns too quickly.
  10. Remove from oven and let cool for 15–20 minutes before serving.
  11. Serve warm with vanilla ice cream, whipped cream, or Greek yogurt.

Notes

For best results, use a mix of tart and sweet apples. Keep butter cold for a crunchy topping. Almond flour and gluten-free oats make this recipe gluten-free. Coconut oil or vegan margarine can be used for dairy-free. Slice apples evenly for even baking. Reheat leftovers in the oven to re-crisp topping. Add nuts, dried fruit, or spices for variations.
