Prep the Peppers: Start by washing the mini sweet peppers thoroughly and then pat them dry with a paper towel. If you prefer, you can slice them in half lengthwise and remove the seeds and membranes for a milder flavor.

Season the Peppers: In a mixing bowl, toss the mini peppers with a drizzle of olive oil. Make sure they are evenly coated. You can also sprinkle them with a pinch of salt and pepper, or any other seasonings of your choice. Mix well to distribute the seasonings evenly.

Preheat the Air Fryer: Preheat your air fryer to around 375°F (190°C). This usually takes about 3-5 minutes.

Arrange in the Air Fryer: Place the seasoned mini sweet peppers in the air fryer basket in a single layer. Avoid overcrowding, as this can prevent even cooking. If necessary, cook them in batches.

Air Frying: Cook the peppers in the air fryer for approximately 8-10 minutes. Pause and shake or flip them halfway through the cooking time. Keep an eye on them to prevent overcooking; they should be tender and have a slight char.

Serve: Once done, remove the roasted mini peppers from the air fryer basket and transfer them to a serving plate. They are now ready to enjoy!
