Step 1: Prepare the Apples
In a medium bowl, combine the peeled, cored, and sliced apples. Add the granulated sugar, brown sugar, flour (or cornstarch), cinnamon, nutmeg, and lemon juice. Toss gently until the apples are evenly coated. This mixture will form the luscious base of your crisp.

Step 2: Make the Oat Streusel Topping
In a separate bowl, combine the rolled oats, flour, brown sugar, cinnamon, and salt. Add the cold, cubed butter. Using your fingertips or a pastry blender, work the butter into the dry ingredients until the mixture resembles coarse crumbs with some larger pea-sized pieces. This creates the signature crispy texture.

Step 3: Assemble the Crisp
Lightly grease an air fryer-safe baking dish or ramekins (approximately 6-inch round or equivalent). Pour the apple mixture into the prepared dish, spreading it evenly. Then, generously sprinkle the oat streusel topping over the apples. Ensure the topping is spread across the entire surface for maximum crispiness.

Step 4: Air Fry the Apple Crisp
Carefully place the baking dish into your air fryer basket. Cook at 350°F (175°C) for 15-20 minutes, or until the apples are tender and the streusel topping is golden brown and crispy. Cooking times may vary depending on your air fryer model and the size of your dish. It’s always a good idea to check for doneness halfway through. For consistent results, consider using a reliable air fryer, like the .

Step 5: Serve and Enjoy
Once cooked, carefully remove the apple crisp from the air fryer. Let it cool for a few minutes before serving. This allows the filling to set slightly. Serve warm, perhaps with a scoop of vanilla ice cream, whipped cream, or a drizzle of Date Caramel Recipe Natures Candy for an extra touch of indulgence.
