This single-serve Air Fryer Apple Crisp is my go-to when I want a fast, simple and healthy dessert ready in under 20 minutes. It’s designed for one portion but scales easily—double, triple or quadruple the ingredients to serve more. The combination of apples, oats and warm spices gives you a comforting dessert without a long bake time.
Recipe Highlights
- Ready in under 20 minutes: an air fryer speeds everything up so you get a warm dessert quickly.
- Single serve: perfect for one—scale up as needed for more servings.
- Healthy ingredients: apples, oats and warming spices form a wholesome base that’s lighter than many traditional desserts.
- Easy to customize: swap the apple for other fruits like blueberries, pears, or strawberry-rhubarb combinations.
- Gluten-free friendly: naturally gluten-free when using certified gluten-free oats; make dairy-free by substituting butter with coconut oil.
Notes From My Kitchen
I love the full-sized Healthy Apple Crisp that takes about an hour to make, but some nights I want something warm and sweet with minimal fuss. This air fryer version was developed for those moments—fast, satisfying and forgiving.
I tested several approaches. Baking the apples and topping together burned the crumble before the fruit softened. Tent-foiling the top prevented burning but steamed the topping, leaving it soggy. The winning method is to cook the apples first, then add the oat topping and air fry briefly to crisp it. That two-stage approach gives tender, saucy apples with a golden, crunchy topping.
Key Ingredients
Main components are simple: diced apple, a little lemon juice and cinnamon for the filling, and a crumbly oat topping made from rolled oats, oat flour, a bit of brown sugar and melted butter (or coconut oil for dairy-free). The ingredient list below gives exact amounts for a single ramekin.
How To Make Air Fryer Apple Crisp
*Overview: the full recipe with exact measurements and step-by-step instructions follows in the recipe card below.
Step 1: Toss the diced apple with lemon juice and cinnamon so the fruit starts to develop flavor and won’t brown.
Step 2: Combine rolled oats, oat flour, cinnamon, brown sugar (or coconut sugar) and melted butter until crumbly.
Step 3: Air fry in two stages: cook the apples first, then add the oat topping and crisp briefly until golden.
Step 4: Let cool for a few minutes so the filling sets slightly, then serve warm.
Can I Make This In The Oven?
Yes. If you don’t have an air fryer, bake this single-serve crisp in the oven at 350°F for about 25–30 minutes until the topping is golden and the filling is bubbling. For multiple servings, use a larger baking dish and adjust the time accordingly.
How To Store
This crisp is best enjoyed fresh while the topping is crisp. Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or air fryer until warmed through to restore crispness.
Jess’s Tips
- Use the right ramekin: a 6–8 ounce oven-safe ramekin works well so apples and topping cook evenly.
- Cook the apples first: giving the fruit its own cooking time ensures tender filling without burning the topping.
- Scale thoughtfully: the recipe multiplies easily, but check how many ramekins fit in your air fryer; you may need batches.
- Breakfast-friendly: with oats and apples, this makes a hearty, dessert-like breakfast the next morning.
- Try other fruits: blueberries, pear with cranberry, or strawberry-rhubarb are all great variations.
- Watch the finish: air fryer heat varies—begin checking the topping around the 4 minute mark of the second stage to avoid over-browning.

Description
This Air Fryer Apple Crisp is a fast, single-serve dessert that delivers tender apples and a crunchy oat topping in under 20 minutes.
Ingredients
For the Apple Filling:
- 1 apple, cored and diced
- 1/4 teaspoon cinnamon
- 1 teaspoon lemon juice
For the Oat Topping:
- 1 tablespoon butter, melted (or coconut oil for dairy-free)
- 1/4 teaspoon cinnamon
- 3 tablespoons rolled oats
- 1 tablespoon oat flour
- 1 tablespoon brown sugar or coconut sugar
Instructions
- Toss the diced apple with the cinnamon and lemon juice in a mixing bowl, then transfer to an oven-safe ramekin.
- Place the ramekin in the air fryer and cook at 300°F (150°C) for 8 minutes to soften the apples.
- While the apples cook, stir together the melted butter (or oil), cinnamon, rolled oats, oat flour, and brown sugar until combined and crumbly.
- Open the air fryer, sprinkle the oat topping evenly over the apples, then continue to cook for another 4–5 minutes, or until the topping is golden and crisp. Start checking at 4 minutes as air fryer heat varies.
- Let cool for a couple of minutes before serving. Use caution handling the hot ramekin.
Notes
- The recipe scales easily; check how many ramekins your air fryer basket will hold and cook in batches if needed.
- Swap the apples for other fruits you enjoy; adjust cooking time slightly for different fillings.
- Different air fryer models vary in intensity—monitor the topping near the end of cooking to prevent over-browning.
