Slice the jalapeño peppers in half after thoroughly washing them. Then, using a small spoon, remove the seeds and white membrane. Optional: For extra kick, you can leave some of the white membrane and seeds.
Prepare the cream cheese filling. Mix the softened cream cheese with mozzarella cheese, chopped spring onion, salt, and ground black pepper.
Fill the sliced and jalapeño peppers with the cream cheese mix. Just fill them flush to the sides of the jalapeños to prevent overflowing when cooking.
Then, set up the breading station. In a medium bowl, beat an egg until smooth. In a separate container, add the Panko-style breadcrumbs.
Preheat the air fryer to 400°F (204°C).
Meanwhile, coat the stuffed portion of the jalapeños with breadcrumbs. First, dip each jalapeño into the egg wash, cut side down. Then, drain off any excess egg wash and transfer the jalapeño to the breadcrumbs gently pressing to coat the stuffed portion with breadcrumbs.
Air fry jalapeno poppers for 6-8 minutes. First, arrange the jalapeño poppers in a single layer, and spray them with high heat cooking oil. Then cook them until the crust becomes golden and crispy.
Serve your air fryer jalapeño poppers warm! Enjoy!
