On a baking sheet, spread your green beans (trim the stems) and drizzle with olive oil and a pinch of salt. Air fry for 5-8 minutes at 450ºF, and cook until crisp and tender, moving halfway if needed. Remove from the oven, place on an extended platter, and squeeze a little lemon juice onto them.
For the lemony-garlic bread crumbs: in a bowl, add panko (about 1 cup) and drizzle with olive (3-4 tablespoons) and a pinch of salt. Mix, then grate in a garlic clove and zest a lemon. Mix well, and don't let the garlic clump! Place on a quarter-size baking sheet and air fry for one minute; mix, air fry for two more minutes, and repeat as needed until golden and crispy. Sprinkle over the green beans.
Notes
The air-fried green beans are best eaten immediately.
You can store it in the fridge in an air-tight container and reheat it in the microwave or a pan over the stove.
