Ingredients

Scale
  • 6 cups peeled, cored, and sliced apples (about 5–6 medium; Granny Smith, Honeycrisp, or a mix)
  • 2 tbsp granulated sugar
  • 1 tbsp cornstarch
  • 1 tsp ground cinnamon
  • 1/4 tsp ground nutmeg (optional)
  • 1/2 tsp lemon juice
  • Pinch of salt
  • 1 cup rolled oats (old-fashioned)
  • 3/4 cup all-purpose flour (or almond flour for gluten-free)
  • 1/2 cup light brown sugar, packed
  • 1/4 cup granulated sugar
  • 1/2 cup unsalted butter, cold and diced
  • 1/2 tsp ground cinnamon
  • Pinch of salt
  • 1/2 cup chopped walnuts or pecans (optional)
  • 1/4 cup dried cranberries or raisins (optional)
  • 1/2 tsp vanilla extract (optional)

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×13-inch casserole dish with butter or nonstick spray.
  2. In a large bowl, combine apples, 2 tbsp sugar, cornstarch, 1 tsp cinnamon, nutmeg (if using), lemon juice, and a pinch of salt. Toss until evenly coated.
  3. Pour apple mixture into the prepared casserole dish and spread evenly. Sprinkle dried fruit or berries over apples if using.
  4. In a medium bowl, mix oats, flour, brown sugar, 1/4 cup sugar, 1/2 tsp cinnamon, and a pinch of salt.
  5. Add cold, diced butter to the oat mixture. Blend with a pastry cutter, two forks, or fingers until coarse crumbs form. Stir in nuts if using.
  6. Evenly distribute topping over apples. Press down lightly.
  7. Place casserole dish on a baking sheet. Bake for 40-45 minutes, until topping is golden brown and apples are bubbling at the edges. Cover loosely with foil if topping browns too quickly.
  8. Let casserole rest for 10-15 minutes before serving to allow filling to thicken.
  9. Serve warm, optionally topped with vanilla ice cream or whipped cream.

Notes

For gluten-free, use almond or oat flour and certified gluten-free oats. For dairy-free, substitute butter with coconut oil or vegan butter. Chill butter before blending for a crisp topping. Let casserole cool before serving for best texture. Add berries or pears for seasonal twists.
