Trim and season the sprouts up to 24 hours in advance and air fry just before serving, or cook fully and reheat briefly. 2) How do I know when the vegetables are done? The centers should be fork-tender and the cut sides well browned with crisp edges. 3) Can I swap fresh herbs for dried herbs in this recipe? Yes. Use one-third the amount if swapping dried for fresh, and add dried herbs with the oil so they bloom.

Ingredients

Instructions

  1. Preheat the air fryer to 375 degrees Fahrenheit for 3 minutes. If desired, line the basket with a perforated parchment liner or set in a shallow perforated baking pan to catch cheese while maintaining airflow.
  2. In a bowl, toss Brussels sprouts with olive oil, salt, pepper, garlic, lemon zest, and red pepper flakes if using.
  3. Arrange sprouts cut side down in a single layer. Air fry for 8 to 10 minutes, shaking the basket once halfway, until the cut sides are well browned and the centers are tender.
  4. Sprinkle Parmesan evenly over the sprouts and air fry for 2 to 3 minutes more, just until the cheese melts and turns golden.
  5. Scatter walnuts over the top and air fry 1 additional minute to lightly toast.
  6. Transfer to a serving bowl, sprinkle with parsley, and serve with lemon wedges. Taste and adjust salt and pepper as needed.
