In a large bowl, add the broccolini, oil, lemon juice, minced garlic, salt, and black pepper. Toss until thoroughly coated.
Transfer the broccolini to the air fryer basket. Make sure to place it in a single layer.
Cook at 390F for 5-6 minutes or until desired doneness.
Serve immediately.
Notes
To store leftovers: Allow the broccolini to cool completely, then transfer it to an airtight container and store it in the refrigerator for up to 2-3 days. Reheat in the air fryer or oven until warmed through.
It's not recommended to freeze cooked broccolini, as it may become mushy and lose its texture when thawed. It's best enjoyed fresh or stored in the refrigerator for short-term storage.
