Ingredients

- ½ teaspoon salt – Essential for seasoning and bringing out the natural taste.
- ¼ teaspoon black pepper – Adds a mild heat and depth of flavor.
- ½ teaspoon dried thyme – Earthy and aromatic. You can also use Italian seasoning.
- 2 tablespoons Parmesan cheese (optional) – Gives a nutty, savory finish with a crispy texture.

Instructions
Step 1: Prepare the Asparagus
Rinse the asparagus under cold water and pat dry. Trim about 1–2 inches off the tough, woody ends.
Step 2: Season the Asparagus
In a large bowl, toss the asparagus with olive oil, salt, black pepper, and dried thyme until evenly coated.
Step 3: Air Fry the Asparagus
Preheat the air fryer to 375°F (190°C). Arrange the asparagus in a single layer in the air fryer basket to allow even cooking.
Step 4: Cook Until Tender
Air fry for 7–9 minutes, shaking the basket halfway through for even crisping. Thinner spears may cook faster, so check for doneness around 6 minutes. The asparagus should be tender with slightly crispy tips.
Step 5: Finish and Serve
Transfer the asparagus to a serving plate. If desired, sprinkle with Parmesan cheese, drizzle with lemon juice, and add a pinch of red pepper flakes. Serve immediately for the best texture and flavor.
FAQs
Can I use frozen asparagus in the air fryer?
Yes! Cook straight from frozen, adding 2–3 extra minutes to the cooking time. The texture will be slightly softer than fresh asparagus.
How do I store and reheat leftovers?
Store in an airtight container in the fridge for up to 3 days. Reheat in the air fryer at 350°F (175°C) for 2–3 minutes to restore crispiness. Avoid microwaving, as it may make the asparagus soggy.
