Rinse and pat dry the asparagus spears thoroughly. Cut off the tough, woody ends from each spear.

Transfer the asparagus to a large plate. Drizzle the olive oil over them, sprinkle with dried thyme, and season with salt and black pepper. Toss gently to ensure an even coating.

Arrange the asparagus in a single layer within the air fryer basket. Set the air fryer to 370°F and cook for 7-9 minutes.

Once done, take the asparagus out of the air fryer, place it on a serving plate, and squeeze fresh lemon juice over the top. Adjust seasoning with additional salt and pepper as desired.
