  • 2 garlic cloves, crushed
  • 1l vegetable stock
  • 100ml crème fraîche, plus extra to serve


  1. Heat oven to 220C/200C fan/ gas 7 and put the sweet potatoes and carrots into a large roasting tin, drizzled with 2 tbsp olive oil and plenty of seasoning. Roast the veg in the oven for 25-30 mins or until caramelised and tender.

  2. Meanwhile, put the remaining 1 tbsp olive oil in a large deep saucepan and fry the onion over a medium-low heat for about 10 mins until softened. Add the garlic and stir for 1 min before adding the stock. Simmer for 5-10 mins until the onions are very soft, then set aside.

  3. Once the roasted veg is done, leave to cool a little, then transfer to the saucepan and use a hand blender to process until smooth. Stir in the crème fraîche, a little more seasoning and reheat until hot. Serve in bowls topped with a swirl of crème fraîche and a good grinding of black pepper.

Lovely soup and easy to make. I didn't use garlic as I didn't have any but added about half a teaspoon of mild curry powder. We definitely make again as so much better than supermarket/tinned soup

Really lovely soup, took note of the person who suggested roasting the veg in coconut oil, I think that doing this really makes it. I don't bother with creme fraiche, as it's so lovely without it anyway. A firm favourite.

This soup is utterly delicious - I can't get enough of it! I thought the consistency was just perfect. The only change I made was to add a little more garlic and also to throw in some fresh red chilli with the onions. Tasty!

Delicious, sweet soup. Made mine with good chicken stock and it was lovely.

Such an easy and tasty soup to make. I made slightly more stock as a comment suggested and it had a lovely consistency; other than that I stuck to the recipe. I'd really make sure those onions are soft before adding the garlic and the stock as they can be hard to blend. I will definitely make this again, I'm looking forward to the leftovers :-)

Just made this today; Pleased with the result. Had to adjust the recipe slightly as I used a few too many carrots then had to replace the Crème Fraîche with Double Cream as I forgot to but any! Also added a dash of Balsamic Vinegar after blending it down.

Lovely recipe - roasted the veg in coconut oil and chilli flakes, and added a few chilli flakes just before blending. Took note of other comments and added in a splash more water as was too thick. The creme fraiche really makes it!

I made this tonight after trying to find something easy to use up some sweet potatoes and it was delicious. I did not use a scale but I´d think the amount was about right, I might have had a little less sweet potato but more carrot but it turnt out great nonetheless. I added a bit of grated ginger at the same time as the garlic (and contrary to an earlier review did not find the garlic overpowering at all) and seasoned my roasted veggies with turmeric, coriander and chilli to spice it up a bit. Did not use any crème fraiche but it was still creamy, filling and simply great for dinner at this time of the year!

Super easy to make and absolutely delicious. This got lots of compliments from friends.

I just made this today, I roasted the veg in coconut oil & seasoned with mixed spice & paprika as well as salt & pepper. It's delicious!

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.
