Preheat your air fryer to 350 degrees for 4-5 minutes. (Some models recommend that you always preheat. So follow the instructions that are provided).
While the air fryer is preheating, pour your frozen broccoli into a large mixing bowl. Add the olive oil, seasoning, salt, and pepper, and toss or shake well, but quickly! You don’t want the broccoli defrosting. This is important.
Add one tablespoon of water to the bottom of the air fryer. This will prevent your air fryer from smoking.
Place the coated vegetables into the air fryer basket in a single layer and cook for 5-8 minutes. The longer you cook your broccoli, the crispier it will get. And remember, the smaller the broccoli florets, the faster they will cook.
Add a drizzle of olive oil and sprinkle more salt and pepper to taste. Enjoy!
