Prep
Trim the stalks and fronds from the bulb, reserving the fronds for garnish. Slice the bulb into halves or quarters through the root end — keeping the root attached holds the layers together during cooking. Rinse and pat dry.
Seasoning
Drizzle with olive oil and season with salt, pepper, and optionally a squeeze of lemon juice. Parmesan added in the last 3 minutes creates a beautiful savory crust. Fennel also pairs well with balsamic glaze.
Temperature and Time
Place fennel cut-side down in the basket. Air fry at 400°F (205°C) for 15–18 minutes, flipping once at the halfway mark. The fennel is done when deeply caramelized on the cut sides and completely tender when pierced with a fork.
Serving
Serve as a side vegetable, over pasta with olive oil and olives, or alongside fish and chicken. Scatter the reserved fronds on top for freshness. Roasted fennel is also excellent in grain bowls.
