Editorial note: This recipe package was developed from established air-fryer methods and food-safety guidance. It has not yet been independently kitchen-tested for Air Crisp Kitchen, so timing should be verified in the reader’s appliance before publication.
Apple crisp is well suited to a small air fryer because the shallow dish heats quickly and the circulating air browns the oat topping.
Covering the dish first gives the apples time to soften before the topping is exposed for its final crisping stage.
Why this apple crisp air fryer method works
- Thin, even apple slices soften consistently.
- Cornstarch thickens the released juice.
- Cold butter forms crisp topping clusters.
- Two-stage cooking protects the topping while the fruit becomes tender.
Ingredient notes
Apples
Use firm baking apples such as Honeycrisp, Granny Smith, or Pink Lady, or combine sweet and tart varieties.
Old-fashioned oats
Rolled oats hold their texture better than instant oats in the topping.
Cold butter
Keep it cold until mixing so the topping forms distinct crumbs rather than a paste.
How to make apple crisp in the air fryer
Build an even fruit layer
Slice the apples evenly and distribute them without large gaps in the dish.
Cover before browning
Foil traps enough heat to soften the fruit before the topping receives direct airflow.
Rest the crisp
A short rest lets the bubbling filling thicken and makes serving easier.
Tips for the best apple crisp
- Check that the baking dish fits before preheating.
- Secure foil so the fan cannot lift it.
- Use oven mitts when removing the hot dish.
- Add 2 to 4 minutes if the apples are still firm.
Storage and reheating
Cover and refrigerate cooled apple crisp for up to 3 days.
Reheat individual portions at 325°F (163°C) until warm; watch the topping closely.
What to serve with apple crisp
Serve warm on its own or with vanilla ice cream, lightly whipped cream, or plain Greek yogurt.
Frequently asked questions
Which dish can go in an air fryer?
Use a small oven-safe metal, ceramic, or tempered-glass dish that the manufacturer approves and that leaves airflow around the sides.
Why are the apples still firm?
Slices may be thick or the variety may be very firm. Re-cover and cook a few minutes more before browning.
Can I use quick oats?
They work, but the topping will be finer and less distinctly crisp than with old-fashioned rolled oats.

Tender cinnamon apples under a crisp brown sugar and oat topping, baked in a small air-fryer-safe dish.

- Prepare the apples: Toss the sliced apples with lemon juice, granulated sugar, half of the cinnamon, and cornstarch.
- Fill the dish: Lightly grease a 7-inch air-fryer-safe baking dish and spread the apples evenly inside.
- Make the topping: Mix oats, flour, brown sugar, salt, and remaining cinnamon. Cut in the cold butter until coarse crumbs form.

Notes
Use only an air-fryer-safe dish with room for air to circulate. Appliance strength, apple variety, and slice thickness can change timing.
