    For me it doesn't get any more comforting that big bowl of steaming roasted vegetable soup.

    I tend to throw bunch of veggie chunks onto the baking tray, roast and when ready blend them with some veggie stock. Et voilà, the soup is ready!

    My Roasted Celeriac & Sweet Potato Soup has turned out so super tasty that I simply had to write it up for the blog so that you can enjoy it too! It's naturally vegan and gluten-free too!

    If you're a fan of roasting your veg for soups you might want to try this creamy Curried Parsnip Soup as well.

    Let roasted veggies do the talking!

    You might have already noticed how extremely simple this soup is!

    Beside two main stars - celeriac and sweet potato, I have also included a parsnip (it needed using up so in it went), onion and lots of garlic!

    Please don't be put off by the amount of garlic used here as when roasted it mellows and becomes sweet rather than pungent. You can of course use as much or as little garlic as you fancy.

    As far as seasoning is concerned, I went with dried thyme (you can use fresh instead if you have some), salt and pepper! That's all this soup needs as roasted veggies do the talking here!

    Useful tip when making Celeriac & Sweet Potato Soup

    I haven't included the exact amount of veggies in grams or ounces as it is a soup and not elaborate bake for which you need to be super exact when it comes to quantities.

    Your soup might have more sweet potato rather than celeriac, maybe two parsnips instead of one or no parsnips at all.

    When it comes to quantities, be relaxed and use more stock if need be to thin your soup out a bit more if it appears too thick. Just enjoy!

    Once roasted put your veg into the large pan or stock pot*, pour in some veggie stock (I use Kallo*) and blend with a simple stick blender* until nice and smooth.

    You can of course use a high speed blender if you want to. I use and highly recommend Froothie Evolve High Speed Blender. If you're interested feel free to check out my Readers' Offer under the recipe card below.

    Ingredients

    Metric - US Customary
    • 1 celeriac peeled and cubed
    • 1 parsnip peeled and cubed
    • 2 sweet potatoes peeled and cubed
    • 1 onion peeled and quartered
    • 4-6 garlic cloves (see notes) peeled
    • 1 tablespoon dried thyme
    • 1.3 ltr vegetable stock from cube is fine
    • salt, pepper, olive/rapeseed oil

    Instructions

    • Preheat the oven to 180C/350F/Gas Mark 4.
    • Prepare all the vegetables as per above and put them on a baking tray or in a roasting tin.
    • Drizzle with some olive/rapeseed oil and sprinkle with dried thyme, salt and pepper and mix everything really well with your hands making sure that your veggies are properly covered with oil and seasoning.
    • Roast in the preheated oven for approx. 30 min or until all the veggies are fork tender.
    • Once tender put all the veggies in the large pan or stock pot and pour over the stock. Puree/blend until smooth adding more stock if you prefer a bit thinner consistency (1.3 ltr of stock will give you quite a thick soup). 
    • Season to taste, heat up if required and serve with a drizzle of olive oil and some homemade croutons. 

    Notes

    • Nutritional information is approximate and should be treated as a guideline only.
    • I've used 6 garlic cloves in this soup which is quite a lot. Roasted garlic does become lovely and sweet but you can definitely taste it. Use as many cloves as you feel comfortable with.
    • Feel free to use chicken stock if you don't need/want for this soup to be veggie/vegan. Stock cubes are absolutely fine and my favourite are Kallo Organic* stock cubes which I use all the time.
    • The amount of stock you use here depends on how thick you'd like your soup to be. I've used 1.3 ltr /5 ½cups which gave me quite a thick soup which is how I like it.
