Ingredients
For the Vegetables
- 500g carrots, peeled and cut into batons
- 500g parsnips, peeled and cut into batons
- 3 tbsp olive oil
- Salt and freshly ground black pepper
For the Glaze
- 50g unsalted butter
- 2 tbsp honey
- 1 tbsp wholegrain mustard
- 1 tbsp fresh thyme leaves (optional)
How to Make James Martin Christmas Carrots And Parsnips
- Prepare the oven: Preheat the oven to 200°C or 180°C fan. Place a shelf in the middle of the oven so the vegetables roast evenly and develop a golden colour.
- Prepare the vegetables: Place the carrots and parsnips in a large roasting tray. Drizzle with olive oil, season well with salt and pepper, and toss to coat evenly.
- Roast the vegetables: Spread the vegetables in a single layer. Roast for 25 to 30 minutes, turning halfway through, until tender and lightly caramelised.
- Make the glaze: In a small pan, melt the butter over low heat. Stir in the honey and wholegrain mustard until smooth and glossy.
- Combine and finish: Remove the vegetables from the oven and pour over the glaze. Toss well to coat, then return to the oven for a further 10 minutes until sticky and golden.
- Serve: Sprinkle with fresh thyme if using, and serve immediately while hot.

Tips
How do I get perfectly caramelised vegetables?
Make sure the vegetables are spread in a single layer with space between them. Overcrowding will cause steaming instead of roasting.
Can I prepare this dish in advance?
Yes, you can parboil or prep the vegetables earlier in the day, then roast and glaze just before serving.
Why are my parsnips too soft?
This usually happens if they are overcooked or cut too small. Keep the pieces evenly sized for consistent texture.
Can I make it less sweet?
Reduce the honey slightly or add a splash of lemon juice to balance the sweetness.
Serving Suggestions
- Serve alongside roast turkey or chicken
- Pair with roast potatoes and gravy
- Add to a festive vegetarian platter
- Enjoy with baked ham or beef

FAQs
Can I use other root vegetables?
Yes, you can add vegetables like sweet potatoes or turnips for variety, but adjust cooking times accordingly.
Do I need to peel the carrots?
Peeling is recommended for a smoother texture, but well-scrubbed carrots can be used unpeeled.
Can I make this dish vegan?
Yes, simply replace the butter with a plant-based alternative and use maple syrup instead of honey.
How do I reheat leftovers?
Reheat in a hot oven for 10 to 15 minutes to restore crisp edges. Avoid microwaving as it softens the texture.
