Ingredients Method

Ingredients
  

  • 1 pound asparagus, trimmed (medium-thick spears are ideal)
  • 1–1.5 tablespoons olive oil
  • 1/4 teaspoon kosher salt (more to taste)
  • 1/4 teaspoon black pepper
  • 1/4 teaspoon garlic powder (or 1 small clove minced)
  • 1/3 cup freshly grated Parmesan cheese (plus extra for serving)
  • 1/2 lemon, for zest and juice
  • Optional: pinch of red pepper flakes, 1 teaspoon butter, chopped parsley

Method
 

  1. Prep the asparagus: Rinse and pat dry. Snap or trim off the woody ends (about 1–2 inches). Aim for pieces of similar thickness so they cook evenly.
  2. Season: In a bowl, toss asparagus with olive oil, salt, pepper, and garlic powder until evenly coated. Add a few swipes of lemon zest if you like a brighter flavor.
  3. Preheat the air fryer: Set to 400°F (200°C) for 3 minutes. A hot basket helps with browning.
  4. Arrange in the basket: Spread asparagus in a single layer. Slight overlap is fine, but avoid piling. Work in batches if needed.
  5. Cook: Air fry for 5–7 minutes, shaking the basket halfway. Thinner spears may be done closer to 4–5 minutes; thicker ones may need 7–8.
  6. Add Parmesan: Sprinkle the asparagus with Parmesan during the last 1–2 minutes of cooking so it melts slightly but doesn’t burn.
  7. Finish: Transfer to a plate. Squeeze a little lemon juice over the top, add extra Parmesan, and a pinch of red pepper flakes if using. For extra richness, dot with a teaspoon of butter and let it melt.
  8. Taste and adjust: Add a pinch more salt or pepper if needed. Serve immediately while hot and crisp.
