📝 About This Recipe

This quintessential British comfort classic features a luscious, jammy filling of tart Granny Smith apples scented with warm cinnamon and a hint of lemon.

It is a timeless dessert that transforms humble orchard staples into a sophisticated, heart-warming masterpiece perfect for any season.

🥗 Ingredients

The Apple Filling

  • 6 large Granny Smith Apples (peeled, cored, and sliced into 1/2-inch wedges)
  • 1/2 cup Granulated Sugar
  • 1.5 teaspoons Ground Cinnamon
  • 1 tablespoon Lemon Juice (freshly squeezed to prevent browning)
  • 1 tablespoon Cornstarch (to thicken the natural juices)
  • 1 teaspoon Vanilla Extract (pure extract preferred)

The Signature Crumble Topping

  • 1.5 cups All-Purpose Flour (spooned and leveled)
  • 1 cup Old-Fashioned Rolled Oats (do not use instant or quick oats)
  • 1 cup Light Brown Sugar (firmly packed)
  • 3/4 cup Unsalted Butter (cold and cut into small cubes)
  • 1/2 teaspoon Sea Salt (to balance the sweetness)
  • 1/4 teaspoon Ground Nutmeg (freshly grated if possible)
  • 1/2 cup Walnuts or Pecans (roughly chopped (optional))

👨‍🍳 Instructions

  1. 1

    Preheat your oven to 375°F (190°C) and lightly grease a 9x9 inch deep-dish baking pan or a 2-quart ceramic baking dish with butter.

  2. 2

    In a large mixing bowl, combine the sliced apples, lemon juice, granulated sugar, 1.5 teaspoons of cinnamon, vanilla extract, and cornstarch.

  3. 3

    Toss the apple mixture thoroughly until every slice is evenly coated in the sugar and spices, then set aside for 10 minutes to allow the juices to begin macerating.

  4. 4

    In a separate medium bowl, whisk together the flour, rolled oats, brown sugar, sea salt, and nutmeg for the topping.

  5. 5

    Add the cold, cubed butter to the dry flour mixture. Use a pastry cutter or your fingertips to rub the butter into the dry ingredients.

  6. 6

    Continue working the butter until the mixture resembles coarse breadcrumbs with some pea-sized lumps remaining for texture.

  7. 7

    If using nuts, fold the chopped walnuts or pecans into the crumble mixture now.

  8. 8

    Pour the prepared apple filling into the greased baking dish, spreading them out into an even layer and scraping all the juices from the bowl into the dish.

  9. 9

    Spoon the crumble topping evenly over the apples. Do not press the topping down; keep it light and airy to ensure a crisp finish.

  10. 10

    Place the dish on a middle oven rack and bake for 40-45 minutes. If the top browns too quickly, tent loosely with foil halfway through.

  11. 11

    The crumble is done when the topping is a deep golden brown and the fruit juices are bubbling up around the edges of the dish.

  12. 12

    Remove from the oven and let it rest for at least 15 minutes before serving. This allows the fruit filling to set and thicken slightly.

💡 Chef's Tips

Always use cold butter for the topping to ensure a crumbly texture rather than a greasy one. Mix apple varieties like Granny Smith with Honeycrisp for a more complex flavor and texture profile. Avoid over-mixing the topping; you want distinct clumps of butter and sugar for the best crunch. If your apples are particularly juicy, add an extra teaspoon of cornstarch to prevent a soggy bottom. Store leftovers in the fridge for up to 3 days and reheat in the oven to restore the topping's crispness.

🍽️ Serving Suggestions

Serve warm with a generous scoop of high-quality Madagascar vanilla bean ice cream. Drizzle with a warm salted caramel sauce for an extra indulgent touch. Pair with a dollop of cold crème fraîche to cut through the sweetness. Enjoy alongside a hot cup of Earl Grey tea or a glass of chilled dessert cider. For a traditional British touch, serve swimming in warm custard (crème anglaise).
