Preheat your air fryer according to the instructions of your air fryer model.
Cut the top off of your jalapeño peppers, then cut them in half lengthwise. With a small spoon, remove the seeds and either scrape or cut out the rib that runs the length of the pepper.
Cut your halloumi into small pieces. Halloumi is harder than mozzarella but not as soft as cream cheese. So the smaller you cut your pieces, the easier it will be to work with. You don’t want large chunks of cheese falling out into the air fryer. Don’t lose your filling!
Stuff your peppers with halloumi and set aside.
When your air fryer is hot, spray a thin layer of oil on the air fryer basket and line up your stuffed peppers in the basket.
Cook at 370 degrees Fahrenheit for 10 minutes on air fryer mode.
Halfway through, or when your air fryer reminds you, add the shredded cheese to the top of your stuffed peppers. The halloumi will be starting to melt but won’t be completely soft at this point. Continue to cook until the timer goes off.
Your Air Fryer Jalapeño Poppers will be very hot when they come out. So let them rest for a few minutes before removing and serving. Enjoy!
Don't feel like you have to use halloumi cheese. You can use any cheese you'd like, as well as fillings or wrappings such as bacon. Below are a few other cheese and topping options.
Sprinkle the top with Parmesan cheese or cheddar cheese
Stuff your poppers with a cream cheese filling or a cream cheese mixture with a few different types of cheese
Wrap your poppers in bacon (You could even use turkey bacon!)
Sprinkle breadcrumbs on top for a nice crunch (You could also use Ritz crackers!)
