Halved the ingredients but added 200ml more stock to thin the soup out. Easy and delicious!

I made this using coconut cream instead of creme fraiche, with a touch of cumin tossed in at the same time as the garlic. I dressed it with a dollop of Greek yoghurt with finely chopped fresh coriander mixed in and a scant throw of toasted cumin seeds. Delicious!

Recently made this and it was so tasty! Roasted the veg for 25-30 mins turning halfway which was perfect, I didn't have any crème fraiche so used some mascarpone which needed using up, so creamy & filling!

The vegetables took over an hour to cook and I had to add the stock and cook for longer. The overwhelming taste was of garlic. I wonder if it would be better if you simply sweated the veg and created soup. Very filling though!

Delicious! I added my onion in with the sweet potato and carrots to caramelise it. I also added in sweet paprika, garlic powder (I didn't have any fresh), a bit of brown sugar and S+P :) I also froze some of mine as it was too much soup for one person so I can now have some of this tasty soup whenever I feel like it!

As with all roast vegetable soups, I cut up the onion into wedges and put it and the garlic in the oven with the sweet potato and carrot. It cooks in the same time and saves on time and energy heating a ring to fry the onion. Less washing up too! Gorgeous soup. The creme fraiche takes away some of the sweetness of the sweet potato.

Really tasty. Added tumeric, cumin and chilli flakes as well as 2 extra cloves of garlic in the roasting tin. Was a bit too sweet without the chilli.

A very tasty soup, didn't bother with the creme fraiche and it was still delightful! Carrots still seemed a bit firm after roasting, but the sweet potato was already soft and starting to catch a little, so rather than continuing to roast I boiled all the veg together for a few minutes in the stock before blending.

Do you need to boil the potatoes at all before putting them in the oven?

Thanks for your question. No you do not need to parboil the potatoes.

I made this to put in the freezer for the holidays and the whole family was surprised as to how delicious it was - I make a lot of soups and this one really hit the mark! We couldn't work out why; unlike some others, we found the garlic fabulous, and the sweetness I suppose comes from roasting the veg. I will definitely be making this one again (and again and again) as it was such a hit with everyone - and it's not always easy to please teenagers!

How many calories would it be per portion if crème fraiche wasn't added?

Full fat crème fraiche contains around 300 Kcals per 100ml so the soup without it would come in at approx 345 Kcals per portion.

if you cut down the oil to 1 tablespoon, which I did, you could probably knock a further 50 cals per portion off!

Can you freeze the whole recipe. I will have some left over and would like to freeze the leftovers?

Yes, this soup will freeze well for about 3 months

Is this gluten free

Yes, there is nothing with gluten in this recipe; unless you use a vegetable stock cube to make the stock, in which case check the packaging as some brands do contain gluten.

I found that the basic recipe was far too bland, even after adding more seasoning than I would normally choose. Then I hit upon the idea of boosting it with a few shakes of cumin, which made all the difference.
