Just made this for lunch as I have a few carrots and sweet potato looking a bit sad. I was worried that it would be a bit bland so added smoked paprika and mild chilli powder too. Delicious! I didn’t find it too thick as other have but I like I thicker soup. Will definitely make again!

This was delicious! I also used coconut oil and roasted carrots for about 10 minutes before adding all of the other veggies. Easy recipe to double if feeding a crowd - I did and everyone loved it

Delicious! Used sour cream as didn't have creme fraiche.

Nice recipe! I only had 1 onion & didn’t have enough sweet potato lurking in fridge so made up the quantity with extra carrots. Also substituted the creme fraiche with a swirl of milk, once soup had cooled.

This was delicious. I put all the vegetables in the oven to roast, (putting carrot in for a while first as it takes longer to roast), and it gave the soup such a lovely flavour, I could really taste the 'roastieness' of it. ( They were in the oven for longer than in the recipe and onions were quite done.) I used one white and one red onion. Needed extra stock when blending, but this was sooooo good. I did not put creme fraiche in or any substitute, it didn't need it. I will definitely make it again.

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!

Fabulous soup. Thanks for the recipe

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!

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.
27th Apr, 2016
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.

Very nice. I added spoon of cumin and paprika, and a thumb of ginger. Spot on :)

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.
