This is a lovely recipe. I kept the sweet potato & parsnip in separate layers, which look pretty on the plate, & changed the topping to mushroom & onion duxelle mixed to a wet sauce with half of the fromage frais. It was lovely.

Beautiful recipe. We had it as a side dish on New Years Eve for a very mixed crowd and everyone loved it.

Delicious recipe. A must with any roast. Everyone I make this for ask for the recipe. Plus its healthy - Hooray!

I gave this a try to see whether I might make it for Christmas. It's fine but I think my old recipe of steamed parsnip mashed with crème fraiche and lots of nutmeg is simpler and better. Nutmeg is a better flavouring for parsnip than sage, in my opinion.
