This cozy classic apple crisp features tender, cinnamon-spiced apples under a blanket of golden oat crumble. It’s simple enough for a Tuesday night but special enough for company, with a perfect balance of sweet, buttery, and crunchy textures.

Ingredients

Scale
  • 6 medium apples (about 2 pounds or 900g), a mix of Granny Smith and Honeycrisp, peeled, cored, and sliced ¼-inch thick
  • ¼ cup (50g) granulated sugar
  • 2 tablespoons (15g) all-purpose flour
  • 1 teaspoon ground cinnamon
  • ¼ teaspoon ground nutmeg
  • 1 tablespoon lemon juice
  • 1 cup (90g) old-fashioned rolled oats
  • ¾ cup (95g) all-purpose flour
  • ½ cup (100g) packed brown sugar (light or dark)
  • ½ cup (113g) unsalted butter, cold and cut into small cubes
  • ½ teaspoon ground cinnamon
  • ¼ teaspoon salt

Instructions

  1. Preheat your oven to 350°F (175°C). Position a rack in the center of the oven.
  2. Prepare the apples: Peel, core, and slice 6 medium apples into ¼-inch thick slices. Place in a medium mixing bowl and toss with 1 tablespoon lemon juice to prevent browning.
  3. Season the apple filling: Add ¼ cup granulated sugar, 2 tablespoons flour, 1 teaspoon cinnamon, and ¼ teaspoon nutmeg to the apples. Toss until every slice is coated. Let sit while making the topping.
  4. Make the oat crumble topping: In a large mixing bowl, combine 1 cup rolled oats, ¾ cup flour, ½ cup packed brown sugar, ½ teaspoon cinnamon, and ¼ teaspoon salt. Whisk together.
  5. Cut in the cold butter: Add ½ cup cold, cubed unsalted butter to the dry ingredients. Using a pastry cutter or two forks, cut the butter into the flour mixture until it resembles coarse meal with pea-sized pieces of butter still visible.
  6. Assemble the crisp: Transfer the seasoned apples to a 9×13-inch baking dish and spread into an even layer. Sprinkle the oat crumble topping evenly over the apples, squeezing handfuls gently to create clumps.
  7. Bake: Place the dish in the preheated oven and bake for 40-45 minutes. At the 30-minute mark, check if the topping is browning too quickly; tent loosely with foil if needed. The crisp is done when the filling is bubbling around the edges and the topping is deep golden brown.
  8. Cool slightly before serving: Let the crisp rest on a wire rack for at least 10-15 minutes to allow the filling to set.

Notes

Use a mix of apple varieties (Granny Smith and Honeycrisp) for best texture. Don’t overwork the crumble topping; visible butter pieces create a crunchy texture. Let the crisp rest after baking to allow the filling to set. For extra crunch, toast the oats beforehand at 350°F for 5-7 minutes. To make gluten-free, use a gluten-free flour blend and certified gluten-free oats. For a vegan version, replace butter with cold coconut oil or vegan butter.
