Preheat the air fryer: Set to 400°F (200°C) for 3 minutes.
A hot basket helps the peppers blister quickly.
Prep the peppers: Rinse and thoroughly dry them. Moisture prevents charring, so make sure they’re really dry.
Toss with oil and season: In a bowl, coat peppers with olive oil and a pinch of salt. Add a light sprinkle of smoked paprika or garlic powder if using.
Load the basket: Arrange peppers in a single layer.
A little overlap is fine, but avoid tightly stacking.
Air fry: Cook for 6–8 minutes, shaking the basket halfway. You’re looking for blistered skins and soft, tender peppers.
Finish and serve: Transfer to a plate, squeeze with lemon or lime, and sprinkle with flaky salt. Serve hot while they’re at peak flavor.
Optional dip: Pair with lemon-garlic aioli or a yogurt-tahini sauce for extra richness.
