Preheat your air fryer to 375°F (if you like it with more charred bits, you can do 400°F).
In a large bowl, toss together the broccoli, olive oil, garlic, black pepper, and salt. The garlic tends to settle to the bottom so make sure you scoop from the bottle to get garlic over everything.
Arrange the broccoli in a single layer in the air fryer. Air-fry for 8-10 minutes, flipping halfway through so that both sides cook evenly. Pro tip: if you want the broccoli to have a more tender texture, add 1 tablespoon of water to the basket.
Squeeze as much lemon juice as you want over the broccoli. Enjoy!
