• Roasting green beans brings out a smoky, caramelized flavor that’s hard to achieve with steaming or boiling.

Ingredient insights: what makes these green beans shine

• Green beans: I prefer fresh, vibrant, and firm. They should snap when broken.
• Olive oil: Light coating is enough; too much makes them greasy and soggy.
• Sea salt: Enhances the natural flavor and balances the smoky notes.
• Lemon zest: Brightens the dish with a fresh, citrus aroma—don’t skip it.
• Parmesan: Adds umami and saltiness—use freshly grated for best flavor.

Key ingredients and their quirks

Olive oil: Adds a glossy sheen and helps with crisping. Use good quality for richer flavor.:

• Green beans: Bright green, firm, and snap when fresh. They develop a smoky, sweet note when roasted.
• They can turn bitter if overcooked, so keep an eye on timing.

Parmesan: Melts slightly and adds a salty, nutty kick. Best added right after roasting.:

• Lemon zest: Releases a burst of citrus fragrance when added hot. Brightens and balances the smoky flavor.
• Use a microplane for fine zest, avoiding the bitter pith.

Substitutions for common ingredients

• Olive Oil: Avocado or neutral oil works—less flavor, same crisping effect.
• Lemon Zest: Lime or orange zest for different citrus notes—still bright and fresh.
• Parmesan: Pecorino or nutritional yeast for different salty, cheesy flavors.
• Fresh herbs: Basil, parsley, or cilantro—add at the end for freshness.
• Sea salt: Flavored salts or Maldon flakes for an extra touch.

Equipment & Tools

• Air fryer: Main appliance for roasting.
• Tongs: Tossing and removing the beans.
• Small bowl: Mixing oil and seasonings.
• Lemon or Parmesan (optional): Adding flavor at the end.

4. Place the beans in the basket, spreading them out evenly.
5. Cook for 8-10 minutes. Shake the basket halfway through.

Common pitfalls and how to fix them
