Ingredients

Filling
  • 2 large apples (Honeycrisp or Gala are my favorites)
  • 2 TBS unsalted butter (melted and slightly cooled)
  • 1/4 cup brown sugar (dark, packed)
  • 1 TBS lemon juice (usr fresh lemon juice if available)
  • 2 tsp cornstarch (or 1 TBS all-purpose flour)
  • 1 tsp cinnamon
  • 1/8 tsp nutmeg
  • pinch of sea salt
Topping
  • 3/4 cup rolled oats (old-fashioned, regular or extra thick)
  • 1/2 cup flour (all-purpose)
  • 1/3 cup brown sugar (dark, packed)
  • 1/4 tsp sea salt
  • 5 TBS unsalted butter (melted and slightly cooled)
  • 1/3 cup pecans or walnuts (chopped, optional)

Instructions

  • Preheat oven to 350°F and grease an 8x8 baking dish.
  • Peel and slice apples and place them in a mixing bowl.
  • Add melted butter, brown sugar, fresh lemon juice, corn starch, cinnamon, nutmeg, and sea salt. Stir to coat.
  • Pour the apple mixture into the prepared baking dish.
  • In the same bowl (because why dirty two bowls), combine the oats, flour, brown sugar, sea salt, and chopped nuts (if using).
  • Stir in melted butter until crumbly.
  • Sprinkle the topping evenly over the apples.
  • Bake for 35–40 minutes, until golden brown and actively bubbling around the edges.
  • Let cool for 15-20 minutes before serving. This gives the apple crisp a change to firm up and scoop well.
  • Store leftovers in an airtight container in the refigerator for 3-4 days or freeze for up to 3 months.
Notes
  • The cornstarch helps with the excess moisture the apples release. You can use 1 tablespoon of flour instead, but the cornstarch thickens the juices without making the filling heavy.
  • If the topping is done before the filling thickens, loosely tent it with foil an continue baking for 5-10 more minutes.
  • Just reuse the same bowl for the crumble. No need to dirty another one.
  • If you want a crunchier topping, bake the apple crisp closer to 40 minutes.
  • Pecans give this a slightly more buttery flavor than walnuts, but both work well for extra crunch and texture.
  • This apple crisp reheats surprisingly well the next day.
