Ingredients

Scale
  • 6 medium apples (about 2 pounds or 900g), peeled, cored, and sliced into ¼-inch wedges
  • ¼ cup (50g) granulated sugar
  • 2 tablespoons (15g) all-purpose flour
  • 1 teaspoon ground cinnamon
  • ¼ teaspoon ground nutmeg
  • 1 tablespoon lemon juice
  • 1 teaspoon vanilla extract
  • 1 cup (90g) old-fashioned rolled oats
  • ½ cup (60g) all-purpose flour
  • ½ cup (100g) packed light brown sugar
  • ¼ teaspoon salt
  • ½ teaspoon ground cinnamon
  • 6 tablespoons (85g) unsalted butter, melted and slightly cooled

Instructions

  1. Preheat your oven to 375°F (190°C). Position the rack in the center. Grease your 8×8 baking dish lightly with butter or nonstick spray.
  2. Make the apple filling: In a medium bowl, combine the sliced apples, granulated sugar, flour, cinnamon, nutmeg, lemon juice, and vanilla extract. Toss until the apples are evenly coated. Let the mixture sit for 5 minutes.
  3. Toast half the oats (optional but game-changing): In a small skillet over medium heat, melt 1 tablespoon of the butter. Add ½ cup of the oats and stir constantly for 2-3 minutes until they smell nutty and turn golden. Transfer to a plate to cool.
  4. Make the oat crumble topping: In a separate small bowl, combine the remaining ½ cup untoasted oats, the flour, brown sugar, salt, and cinnamon. Pour in the melted butter and stir with a fork until the mixture looks like wet sand with some clumps. Fold in the toasted oats gently.
  5. Assemble the crisp: Pour the apple mixture into your prepared baking dish and spread it into an even layer. Sprinkle the oat crumble topping evenly over the apples. Don’t press it down.
  6. Bake for 40-45 minutes. The crisp is done when the topping is golden brown and the filling is bubbling around the edges. If the topping starts browning too quickly (around the 30-minute mark), tent the dish loosely with foil.
  7. Cool for at least 15 minutes before serving.

Notes

For a gluten-free version, use oat flour or a 1:1 gluten-free blend in the topping and filling, and ensure oats are certified gluten-free. For a vegan version, use melted coconut oil or vegan butter. The double-toasting technique for the oats helps the topping stay crunchy even the next day. Let the crisp rest for 15-20 minutes after baking to allow the filling to set properly.
