  1. In a large pan of boiling salted water, cook the parsnips and swede, covered, for about 20 minutes until tender. Drain well, then mash them together using a masher or food processor until reasonably smooth but still with a bit of texture. Stir in the soured cream, horseradish and thyme and season with salt and pepper.

  2. Spoon into a buttered shallow ovenproof dish and put to one side.

  3. Make the topping. Melt the butter in a frying pan and cook the onion for 5-6 minutes, until gorgeously golden. Mix in the breadcrumbs and stir to brown and crisp a little. Season with salt and pepper and add the thyme. Take the pan off the heat. Spoon the mixture casually over the top of the mash. Scatter over the parmesan. (Can be made ahead to this point and kept covered in the fridge for up to a day. Or can be frozen for up to a month.)

  4. Bake with the turkey (190C/gas 5/ fan 170C) for 35-40 minutes if doing from cold, 25-30 minutes if not, or 11⁄2-13⁄4 hours from frozen (put foil on top, and remove it for the last 10 minutes) – until golden and crisp on top. Serve scattered with a few more thyme sprigs and leaves.

Tastes great, a real treat if served with something mildly sweet.

A legend in my family now! I don't like horseradish & didn't have sour cream so I subtituted with creme fraiche & some dijon mustard - wonderful! Have been asked to make this for every family occassion since!

I make this with sweded and carrots, as we don't like turnips. So I guess it's a little like an upmarket version of "neeps & tatties." My four year old son doesn't like swede, horseradish OR sour cream, but he will happily eat this. It's great mixed in with mashed potatoes, and we also like it as an alternative topping on cottage pie.

I made this on bonfire night and it went down a storm, especially with the veggies! Will definately be making ahead and popping into the freezer ready for Christmas Day.

This tastes gorgeous, I've made it a couple of times, been asked for the recipe by several people and it is a firm favourite at Christmas.
