Roast parsnips are a British Sunday lunch staple, and the Ninja Air Fryer makes them exceptionally crispy with far less oil than a traditional oven. This method delivers golden, caramelised edges and a tender centre in about half the time, making it perfect for busy weeknights or holiday feasts. The key is parboiling the parsnips first to ensure they cook through evenly while the air fryer works its magic on the exterior.
Ingredients
- 500 g (1 lb 2 oz) parsnips, peeled and cut into even batons (about 7-8 cm / 3 inches long, 2 cm / ¾ inch thick)
- 1 tablespoon olive oil (or rapeseed oil)
- 1 tablespoon plain flour (optional, for extra crispiness)
- ½ teaspoon salt (plus more for boiling)
- ¼ teaspoon black pepper
- Optional: 1 teaspoon honey or maple syrup, ½ teaspoon smoked paprika, or fresh thyme leaves
Instructions
- Bring a large pot of salted water to a boil. Add the parsnips and parboil for 5 minutes. Drain well and let them steam dry for 2-3 minutes in the colander.
- Transfer the parsnips to a bowl. Drizzle with the oil, sprinkle with salt, pepper, and flour (if using). Toss well until every piece is coated.
- Preheat your Ninja Air Fryer to 200°C (400°F) for 3 minutes.
- Place the parsnips in the air fryer basket in a single layer. Do not overcrowd – cook in batches if necessary.
- Air fry at 200°C (400°F) for 15-18 minutes, shaking the basket halfway through, until golden brown and crispy on the outside and tender inside. If you added honey or maple syrup, add it in the last 3 minutes of cooking to prevent burning.
- Season with extra salt if needed and serve immediately.
Tips
- Don’t skip parboiling: This softens the parsnips so they cook evenly in the air fryer without burning on the outside. For extra-crispy results, let them dry thoroughly before adding oil.
- Cut evenly: Thicker pieces will take longer; aim for uniform batons so everything cooks at the same rate.
- Use the right oil: Olive oil or rapeseed oil work best. Avoid butter as it can burn at high temperatures.
- Batch cooking: If making a large batch, keep cooked parsnips warm in a low oven (100°C / 212°F) while you cook the rest.
Serving Suggestions
Serve these roast parsnips alongside a traditional roast chicken, beef, or nut roast. They also make a great addition to a Sunday roast dinner with Yorkshire puddings, roast potatoes, and gravy. For a lighter meal, toss them into a warm salad with goat’s cheese and walnuts.
Variations
- Honey & Thyme: Add 1 teaspoon honey and a few fresh thyme leaves in the last 3 minutes of cooking for a sweet, herby glaze.
- Spiced: Mix in ½ teaspoon ground cumin, coriander, or curry powder with the oil for a fragrant twist.
- Parmesan: Sprinkle 2 tablespoons grated Parmesan over the parsnips halfway through cooking for a savoury, cheesy crust.
- Maple & Mustard: Whisk 1 teaspoon maple syrup with 1 teaspoon Dijon mustard and brush over the parsnips before the last 5 minutes.
Storage and Reheating
Store leftover roast parsnips in an airtight container in the fridge for up to 3 days. To reheat, place them in the air fryer at 180°C (350°F) for 3-4 minutes until hot and crispy. They can also be reheated in a microwave, but they will lose their crispiness. Freeze cooked parsnips in a single layer on a baking sheet, then transfer to a freezer bag for up to 1 month; reheat from frozen at 200°C (400°F) for 6-8 minutes.
Frequently Asked Questions
Do I need to peel parsnips? Yes, unless they are very young and thin-skinned. Peeling removes the tough outer layer and ensures a tender texture.
Can I use frozen parsnips? Yes, but skip the parboiling. Add 5-7 minutes to the cooking time and toss with oil and seasoning directly from frozen.
Why are my parsnips not crispy? The most common reasons are overcrowding the basket (which traps steam) or not drying them well after parboiling. Make sure they are in a single layer and thoroughly dry before adding oil.
Can I make them ahead of time? You can parboil and coat the parsnips up to a day ahead, then store them in the fridge. Air fry them just before serving – they may need an extra 2-3 minutes.
What temperature should I use? 200°C (400°F) is ideal for crispy results. If your Ninja Air Fryer runs hot, reduce to 190°C (375°F) and adjust cooking time slightly.
Can I cook them without oil? Yes, but they will be less crispy and more prone to drying out. If using no oil, spray the basket with a little oil to prevent sticking and check them earlier.
