Add the ghee or olive oil to the Instant Pot, hit Sauté, and Adjust so it’s on the More or High setting.
Once it’s melted and bubbling (about 3 minutes), add the leeks and sauté for 10 minutes. They will unravel while being stirred. (NOTE: Don’t worry if some of the leeks look burnt—they taste even better with a bit of a char!)
Meanwhile, put the broccoli florets in a microwave-safe bowl, add about 1/4 inch of water, cover with plastic wrap, and microwave for 3–4 minutes, until tender (if frozen, microwave for 9–10 minutes). Drain.
Add the broccoli to the pot and stir. Squeeze the lemon juice all over everything. Hit Keep Warm/Cancel to turn the pot off.
Add the air fryer lid, hit Broil (400°F) for 10 minutes, and hit Start to begin. Allow it to roast, stirring midway through. If you want it roasted longer, air fry for longer.
Transfer the veggies to a serving dish and enjoy.
Notes
JEFF’S TIP: If you don’t have the air fryer lid, turn the oven to broil, place the veggies on a foil-lined baking sheet, and broil for 5–10 minutes (keep an eye on them so they don’t burn, as ovens vary).
