Prep Time10 minutes
Cook Time18 minutes
Total Time38 minutes
Servings: 4

Ingredients

For the Apple Filling:

  • 4 medium apples Honeycrisp, Granny Smith, or a mix, peeled, cored, and sliced 1/4-inch thick
  • 2 tablespoons brown sugar light or dark
  • 1 tablespoon lemon juice
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg optional
  • 1 teaspoon vanilla extract
  • 1 tablespoon cornstarch or arrowroot
  • Pinch of salt

For the Oat Crisp Topping:

  • 3/4 cup old-fashioned rolled oats
  • 1/2 cup almond flour or all-purpose flour
  • 1/3 cup brown sugar
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon kosher salt
  • 6 tablespoons cold unsalted butter cut into small cubes (or 5 tablespoons coconut oil for dairy-free)
  • 1/3 cup chopped pecans or walnuts optional

To Serve (Optional):

  • Vanilla ice cream whipped cream, or a drizzle of maple syrup

Instructions

  • Prep the apples: Peel, core, and slice the apples into even 1/4-inch slices.
  • Place them in a medium bowl.
  • Season the filling: Add brown sugar, lemon juice, cinnamon, nutmeg, vanilla, cornstarch, and a pinch of salt to the apples. Toss until every slice looks glossy and evenly coated.
  • Make the crisp topping: In another bowl, combine oats, almond flour, brown sugar, cinnamon, and salt. Add the cold butter cubes.
  • Use your fingers or a pastry cutter to work the butter into the dry ingredients until you have pea-sized crumbs. Stir in nuts if using.
  • Choose your dish: Use a small oven-safe baking dish or 6–7-inch cake pan that fits in your air fryer basket. Lightly grease it with butter or spray.
  • Assemble: Spread the apple filling evenly in the dish.
  • Sprinkle the oat topping over the apples, pressing it gently so it adheres but doesn’t compact too tightly.
  • Preheat the air fryer: Set the air fryer to 350°F (175°C) for 3 minutes to warm up. Preheating helps the topping brown better.
  • Cook: Air fry at 350°F (175°C) for 16–22 minutes, until the topping is deep golden and the apple juices are bubbling at the edges. Start checking at 15 minutes.
  • If the top browns too fast, tent it loosely with foil.
  • Rest: Let the crisp sit for 5–10 minutes. This helps the juices thicken and makes serving easier.
  • Serve: Spoon warm apple crisp into bowls. Top with ice cream, whipped cream, or a drizzle of maple syrup for extra indulgence.
