Brown-Butter Apple Crumble

6 dessert portions Active 25 min Total 1 hr 20 min

Browned butter gives a familiar apple crumble a deeper, toasted aroma without adding more sweetness. It goes into the oat topping, where the flour and sugar catch its nutty flavor. The apples underneath need only a little lemon and sugar, especially when you use a mixture of sweet and tart varieties. Keep the fruit pieces similar in size so they soften together, and let the baked crumble stand before serving. The short rest thickens the juices while leaving the topping warm and crisp.

Watch the milk solids

Butter first melts, then foams as its water cooks away. Under the foam, small pale specks settle on the pan’s base. Stir and watch those specks: when they turn amber and smell toasted, pour the butter into a heatproof bowl immediately. The hot pan can carry it from brown to burnt after the heat is off. Scrape the browned specks into the bowl too, because they hold much of the flavor.

Let the fruit determine the tenderness

An eight-inch dish gives the apples enough depth to stay juicy without burying them beneath too much topping. Firm apples may need the longer baking time. Check through a gap near the middle with a small knife; it should slide through without resistance. Bubbling juice at the edges is another useful sign, since the cornstarch needs heat to thicken. If the topping is ready before the apples, lay foil loosely over it and continue baking.

Serve without hiding the top

Spoon through a crisp patch of topping and down to the fruit so every portion has both. A shallow serving bowl leaves the crumble’s texture visible. It is satisfying on its own; any cream or ice cream can be added separately according to the occasion. For a larger group, double the recipe in a nine-by-thirteen-inch dish and allow extra time for the center to become tender.

Ingredients

  • 6 tablespoons unsalted butter (85 g), plus a little for the dish
  • 2 pounds peeled, cored apples, cut into 3/4-inch chunks (900 g prepared)
  • 1/4 cup granulated sugar (50 g)
  • 1 tablespoon fresh lemon juice
  • 1 tablespoon cornstarch (8 g)
  • 3/4 cup all-purpose flour (90 g)
  • 1/2 cup old-fashioned rolled oats (45 g)
  • 1/3 cup packed light brown sugar (70 g)
  • 1/4 teaspoon ground cinnamon
  • 1/4 teaspoon fine salt

Set out

8-inch square baking dish, Small light-colored saucepan, Mixing bowls, Heatproof spatula

Allergens

Milk, wheat. Check ingredient labels and substitutions.

Make it

  1. Heat the oven to 375°F/190°C. Butter an 8-inch square baking dish.
  2. Melt the 6 tablespoons butter in a small light-colored saucepan over medium heat. Cook for 3–5 minutes, swirling or stirring, until the milk solids turn amber and smell nutty. Immediately pour into a heatproof bowl, scraping in the brown specks. Cool for 5 minutes.
  3. Toss the apples with the granulated sugar, lemon juice, and cornstarch. Spread in the baking dish.
  4. Mix the flour, oats, brown sugar, cinnamon, and salt. Stir in the browned butter until irregular crumbs form.
  5. Scatter the topping evenly over the apples without pressing it down. Bake for 35–40 minutes, until the topping is golden, the juices bubble at the edges, and a small knife passes easily through the apples. Cover loosely with foil if the top darkens before the fruit softens.
  6. Rest for 15 minutes before serving.

A useful detail

Measure the butter before browning; its finished weight will be lower because some water evaporates.

Make it your own

  • Replace one-third of the prepared apple weight with firm pears.
  • Add 1/4 cup (30 g) chopped walnuts to the topping; this introduces a tree-nut allergen.

Keep it well

Refrigerate covered leftovers within 2 hours, or 1 hour above 90°F/32°C, at 40°F/4°C or colder for up to 4 days. Reheat portions covered to 165°F/74°C, then uncover briefly to crisp the top.
