Prep the parsnips: Peel and trim the ends. Cut into even sticks about 3–4 inches long and 1/2-inch thick.
Uniform pieces cook more evenly.
Preheat the air fryer: Set to 380°F (193°C) for 3–5 minutes. A hot basket helps with browning.
Mix the seasoning: In a large bowl, whisk olive oil, honey, salt, pepper, garlic powder, and paprika or chili flakes if using.
Toss to coat: Add parsnip sticks to the bowl and toss well until every piece is glossy. If the honey is thick, warm it slightly so it spreads more easily.
Arrange in the basket: Lightly spray the basket.
Spread parsnips in a single layer with a little space between pieces. Work in batches if needed.
Air fry and shake: Cook for 10 minutes, then shake or turn. Cook another 6–10 minutes, until edges are deep golden and centers are tender.
Total time is typically 16–20 minutes depending on thickness and your air fryer model.
Finish and serve: Toss with a squeeze of lemon juice or a sprinkle of zest, and garnish with herbs. Taste and adjust salt. Serve hot.
