Steps-by-step Instructions for the Air Fryer Apple Crips
Chop your apples into bite-sized pieces, about half an inch. I leave the skins on, honestly, it's less work and you get a bit more texture. Peel them if that's not your thing though, totally works either way.
Mix the filling. Toss your apples with the sugar, corn starch, cinnamon, nutmeg, and lemon zest in a bowl. Stir until every piece is coated. This is the part where my kitchen starts smelling like fall no matter what month it is.
Build the topping. In a separate bowl, mix your oats, flour, sugar, cinnamon, nutmeg, and salt. Pour in that melted butter and mix with a fork until it turns crumbly, kind of like wet sand with little pea-sized clumps. That texture right there is what gives you the crisp.
Load up your dishes. Split the apple mixture between 4 small ramekins, or use one 6-inch dish if that's what fits in your basket. Press the apples down just a little so they settle in.
Top it off. Sprinkle your oat mixture over the apples. Here's the thing though, don't press it down. Leave it loose and crumbly so the hot air can actually crisp the top instead of just melting it into a paste.
Air fry it. Pop your ramekins or dish into the basket and set it to 375°F for 15 minutes. You're looking for a topping that's golden brown, with the apples bubbling around the edges. That bubbling is honestly one of my favorite parts to watch through the air fryer window.
Test for doneness. Poke a fork into the apples. If they still feel a bit firm, give it another 2 to 3 minutes.
Let it cool. Give it about 5 minutes before diving in. I know it's tempting, but that filling comes out volcano hot.
Things I Learned Making This Recipe
The first time I made this, I didn't zest the lemon and honestly, it was fine, but it was missing something. Adding that little bit of zest made such a difference, it just brightens everything up without making it taste lemony at all.
Also, I once pressed the topping down thinking it would hold together better. Big mistake. It came out kind of gummy instead of crisp. Loose and crumbly really is the way to go here.
Easy Ways to Customize This Recipe
Swap the apples for pears if that's what you've got on hand, works beautifully. You can also toss in a handful of chopped pecans or walnuts into the topping for some crunch. If you want it a little richer, add a splash of vanilla extract to the apple mixture. And if you're not a nutmeg fan, just leave it out, the cinnamon carries plenty of flavor on its own.
Here's What I Serve With This
This apple crisp is basically begging for a scoop of vanilla ice cream on top, the warm and cold contrast is chef's kiss. If you want to round out a full dessert spread, pair it with [your linked recipe here] or serve it alongside a mug of something warm.
If You Have Leftovers
Pop any leftovers in an airtight container and store in the fridge for up to 3 days. To reheat, I like popping it back in the air fryer at 350°F for a few minutes to bring that crispy topping back to life. Microwaving works too, but you'll lose some of that crunch.
FAQ
Can I make this apple crisp ahead of time?
You can prep the apple filling and the topping separately and store them in the fridge for up to a day before cooking. Just don't combine them until you're ready to air fry, or the topping will get soggy sitting on those juicy apples.
Do I need to peel the apples?
Nope, totally optional. I usually skip it for the extra texture and because, let's be honest, one less step.
Can I double this recipe?
You can, just keep in mind you'll need to cook it in batches depending on your air fryer size, or use a larger dish if it fits your basket. Cooking time might need a few extra minutes too.

Notes
