Key Ingredients & Substitutions
Apples: Gala or Fuji are my favorites for sweetness and texture, but you can use Granny Smith for a tart kick. If you’re in a pinch, any firm apple will do!
Lemon Juice: This helps prevent the apples from browning and adds a nice tang. If you’re out of lemon, a splash of vinegar can work too.
Sugars: I like using both granulated and brown sugar for depth of flavor. If you’re reducing sugar, use less of each or substitute with honey or maple syrup, but adjust the quantity as needed.
Oats: Old-fashioned oats give a great texture. If you only have quick oats, those can work, but the crunch may be softer. You can also use gluten-free oats for a gluten-free version.
Butter: Unsalted butter is best for controlling the saltiness. Coconut oil or vegan butter are great alternatives if you want a dairy-free option!
How Do I Get the Perfect Topping for My Apple Crisp?
The topping is key for a delicious apple crisp. Mixing your dry ingredients with cold butter until it resembles crumbs is essential. Here are the steps:
- In a bowl, combine oats, flour, and brown sugar.
- Add cold, cubed butter; use your fingers to work it into the dry mix until crumbly.
- This mix needs to have tiny lumps for that crunchy topping we love. Don’t overmix!
Make sure to evenly spread the topping over the apple layer before cooking. This helps ensure everything cooks evenly in the air fryer.

Step-by-Step Instructions:
1. Preheat the Air Fryer:
Start by preheating your air fryer to 350°F (175°C). This helps ensure your apple crisp cooks evenly and perfectly crispy.

In a mixing bowl, toss the diced apples with lemon juice, granulated sugar, ground cinnamon, nutmeg, and salt. Mix until the apples are well coated. Set this delicious mix aside.

In another bowl, combine the rolled oats, flour, and brown sugar. Add the cold butter cubes to this mixture. Using your fingers or a pastry cutter, mix everything until it resembles coarse crumbs. This will create that crunchy topping we all love!
4. Assemble the Crisp:
Now, take an air fryer-safe baking dish or ramekin and transfer the apple mixture into it, spreading it evenly across the bottom. Then, sprinkle the oat topping generously over the apples.
5. Cook in the Air Fryer:
Carefully place the dish in the air fryer basket. Cook at 350°F (175°C) for about 15-18 minutes, or until the topping is golden brown and the apples are tender. Keep an eye on it to ensure it doesn’t burn!
6. Serve and Enjoy:
Once done, carefully remove the dish from the air fryer and let it cool slightly. Then serve warm, topped with a scoop of vanilla ice cream or whipped cream if you like. Enjoy your delicious Air Fryer Apple Crisp!

How Do I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, pop it back in the air fryer at 350°F (175°C) for about 5-7 minutes until warmed through for that fresh-out-of-the-oven taste!
