These air fryer roast potatoes and parsnips are a quick, hands-off side dish that delivers crispy edges and tender, sweet centers without turning on the main oven. The hot circulating air browns the vegetables beautifully in about half the time of traditional roasting, making them perfect for weeknight dinners or holiday meals when oven space is precious.
Ingredients
- 1 lb (450 g) russet or Yukon Gold potatoes, peeled and cut into 1½-inch chunks
- 1 lb (450 g) parsnips, peeled and cut into 1½-inch chunks (core removed if woody)
- 2 tbsp (30 ml) olive oil
- 1 tsp (2 g) dried rosemary or thyme
- ½ tsp (3 g) salt, plus more to taste
- ¼ tsp (0.5 g) black pepper
- Optional: 1 clove garlic, minced, or ½ tsp garlic powder
Instructions
- Place the cut potatoes in a medium pot and cover with cold water. Add a generous pinch of salt. Bring to a boil and cook for 5 minutes (parboiling helps create a fluffy interior). Drain well and let steam dry for 2–3 minutes.
- In a large bowl, toss the parboiled potatoes and raw parsnips with olive oil, rosemary, salt, pepper, and garlic (if using). Make sure every piece is lightly coated.
- Preheat your air fryer to 400°F (200°C) for 3 minutes.
- Transfer the vegetables to the air fryer basket in a single layer. Do not overcrowd—cook in batches if needed. For extra crispiness, give the basket a shake after 10 minutes.
- Cook for 20–25 minutes total, shaking the basket every 8–10 minutes, until the potatoes and parsnips are golden brown and fork-tender. If you like them extra crispy, add 2–3 more minutes, watching closely to prevent burning.
- Season with additional salt to taste and serve hot.
Tips
- Don’t skip parboiling the potatoes: it softens the exterior, which then crisps up beautifully in the air fryer. For parsnips, parboiling is optional—if you prefer them firmer, add them raw as directed.
- Cut pieces evenly: aim for similar sizes so everything cooks at the same rate. If your parsnips are thick, halve the core if it’s woody, as it can be tough.
- Work in batches: overcrowding traps steam and makes vegetables soggy. If your air fryer is small, cook in two batches and keep the first batch warm in a low oven.
- Use the right oil: olive oil or avocado oil works well; avoid butter as it can burn at high temperatures.
Serving Suggestions
These roast potatoes and parsnips are a classic British side, perfect alongside roast chicken, beef, or lamb. They also pair well with vegetarian mains like lentil loaf or mushroom wellington. For a festive touch, toss with fresh chopped parsley before serving.
Variations
- Honey-glazed: Drizzle 1 tbsp (15 ml) honey over the vegetables in the last 5 minutes of cooking for a sweet, caramelized finish.
- Spiced: Add 1 tsp smoked paprika or curry powder along with the salt and pepper for a smoky, warm flavor.
- Herb butter: Toss the cooked vegetables with 1 tbsp (14 g) melted butter and chopped chives instead of oil.
- Root vegetable mix: Swap half the parsnips for carrots or sweet potatoes, cut into similar sizes, and adjust cooking time if needed.
Storage and Reheating
Refrigerate leftovers in an airtight container for up to 4 days. To reheat, place in the air fryer at 350°F (175°C) for 3–5 minutes until hot and crisp. You can also reheat in a 400°F (200°C) oven for 5–7 minutes. Avoid microwaving, as it will make them soft.
Frequently Asked Questions
Can I use sweet potatoes instead of regular potatoes? Yes, but they cook faster and may become too soft. Cut them slightly larger and check for doneness at 15 minutes.
Do I need to peel the parsnips? Peeling is recommended for a smoother texture, but if the skins are thin and you prefer rustic, scrub well and leave them on.
Why are my potatoes not crispy? The most common reasons are overcrowding, not parboiling, or not shaking the basket enough. Make sure pieces are dry before oiling and cook in a single layer.
Can I prep these ahead of time? Yes, you can cut and parboil the potatoes up to a day ahead. Store them in cold water in the fridge, then drain and pat dry before tossing with oil and cooking.
What if I don’t have an air fryer? You can roast them in a 425°F (220°C) oven for 30–35 minutes, turning halfway, on a baking sheet.
Can I use frozen parsnips? Yes, but thaw and pat them completely dry before oiling to avoid excess moisture. Reduce cooking time by about 5 minutes.
