Instructions

Preheat air fryer to 380°F for 2–3 minutes (if your model recommends preheating).

Season: In a bowl, toss green beans with olive oil, garlic powder, salt, and pepper until evenly coated.

Air fry: Add beans to the basket in a single layer (cook in batches if needed). Cook 8–10 minutes, shaking halfway, until crisp-tender with a few blistered spots.

Finish: Immediately toss with Parmesan (and lemon zest or a squeeze of lemon if using). Serve hot.

Notes

Cooking tips

Dry the beans well so they blister instead of steaming.
Don’t overcrowd the basket—airflow = crispier beans.
Add Parmesan at the end for the best flavor (it can burn if added too early).
For extra crunch, cook 1–2 minutes longer, watching closely.

Variations

Lemon Garlic: Use fresh minced garlic + finish with lemon zest and juice.
Spicy: Add red pepper flakes or a pinch of cayenne.
Italian Herb: Toss with 1/2 tsp Italian seasoning and a sprinkle of extra Parmesan.
Breadcrumb Crunch: After cooking, toss with 1–2 tbsp toasted panko + Parmesan.
Balsamic Finish: Drizzle with 1–2 tsp balsamic glaze right before serving.
