Recipe Tips

  • Choose firm baking apples, or combine tart and sweet varieties.
  • Cut slices to a similar thickness so they cook evenly.
  • Use cold butter and work it into small clumps for a crisp topping.

Common Mistakes to Avoid

  • Do not slice apples too thick or they may remain firm.
  • Do not melt the butter; it can make the topping dense.
  • Let the crisp rest before serving so the juices thicken.

Variations

  • Add chopped pecans or walnuts to the oat topping.
  • Stir a pinch of nutmeg into the cinnamon.
  • Serve with whipped cream or vanilla ice cream.

Storage

Cover and refrigerate leftover apple crisp for up to 4 days.

Reheating

Warm individual portions in a 325°F oven until hot, or microwave briefly. The oven helps the topping crisp again.

Make Ahead

Prepare the crumble and refrigerate it separately. Slice and season apples shortly before baking to prevent browning.
