Dishing up steaming ladles of this roasted vegetable soup with chunks of fresh bread is one of my favourite ways to enjoy lunch over Winter.
This soup is packed with nutritious vegetables. I love to roast them until golden and caramelized to add lots of extra flavour. Throw in some parmesan too for a creamy finish.

A rainbow of vegetables, roasted until sweet, tender. All blended together with stock and creamy-yet-sharp parmesan and you’ve got the perfect lunch to warm you up from the inside.

I love making easy meals like this in winter. There’s something about dishing up ladles of steaming hot soup into waiting bowls. Dunking a nice wedge of bread in there, knowing you’re eating something nutritious, homemade and absolutely delicious.

👩‍🍳PRO TIP Make a large batch of this pureed vegetable soup to last for the week. Simply cool, cover and refrigerate. You could also split into separate portions and freeze in a sealed container. Just defrost and thoroughly reheat for a super quick lunch.

Can I make it without roasting the vegetables?

You can, of course, make this veggie soup without roasting the vegetables – just boiling them up with the spices in the stock for 20 minutes will give you a lovely soup. But roasting them? It just adds a wonderful sweet and slightly smoky flavour. You can even enhance that smoky flavour by using smoked paprika.

  • Place the chunks of sweet potato, red and yellow bell peppers, carrots, and garlic cloves (skin on) on a large baking tray.
    1 large sweet potato, 1 red bell pepper, 1 yellow bell pepper, 2 medium carrots, 3 cloves garlic
  • Drizzle on the olive oil and sprinkle on the salt, pepper, cumin, and paprika. Toss it all together using your hands.
    3 tbsp olive oil, ½ tsp salt, ½ tsp ground black pepper, ½ tsp paprika, ½ tsp ground cumin
  • Place in the oven for 20 minutes, turning everything over after 10 minutes.
  • After the 20 minutes, add the red onion wedges and toss everything together again so the onion also gets coated in oil.
    1 red onion
  • Place back into the oven for a further 10-12 minutes until the vegetables are tender and slightly caramelized. Remove from the oven.
  • Put a couple of tablespoons of the roasted vegetables to one side and place the rest in a large saucepan. Squeeze the garlic out of their skins into the pan too.
  • Pour in the stock. Bring to the boil and simmer for five minutes. Turn off the heat and then blend with a hand blender.
    1 litre (4 1/4 cups) vegetable stock
  • Stir in the parmesan and season to taste.
    35 g (1/3 cup) grated parmesan
  • Serve topped with the reserved roasted vegetables, a sprinkling of grated parmesan and a few sprigs of fresh thyme.
    2 tbsp grated parmesan, a few sprigs of fresh thyme


Can I make it ahead?
Yes, make the soup, then cool, cover and refrigerate for 2-3 days. Cover and store the reserved roasted veg too.
Reheat in a pan until piping hot, adding the reserved roasted vegetables to the top for the last minute to heat them through.
Can I freeze it?
Yes, make the soup, then cool, cover and freeze. Defrost overnight in the refrigerator.
Reheat in a pan until piping hot.
If freezing I would recommend blending up all of the roasted vegetables, rather than reserving some, as they may go mushy upon defrosting.

    One of my absolute favourite. Converted my soup hating daughter!

  3. Annette says:

    I don’t know what happened. My veggies burned after 40 minutes. I even added extra oil after 20 minutes due to them seeming to cook too quick. I’m really bummed because I really wanted to try this delicious soup.

    Well this is the second time I’ve made it in a week – I’m loving this soup! I used my homemade chicken stock, added 2 tomatoes, chilli flakes and only used Parmesan as a garnish! And if you can resist eating it straight away and leave it in the fridge overnight, it ‘matures’ becoming even more flavoursome! This really is worth making! 🤩

    OMG – this was delicious! I didn’t think vegetable soup could be so good! 😊 I put in one large tomato which needed using up and I forgot the Parmesan completely (how I managed that I don’t know as I like cheese on nearly everything!) …… so simple/easy to make. This will now be my favourite soup to make ….. thank you so much 🙏

  8. Tat Walker says:

    Thanks just the recipe that I was looking for. I also wanted to know, instead of using Stock can I use Broth instead?

  9. Michele says:

    Quick, easy, very healthy, easy to follow instructions, great to pre cook for after work dinners with fresh crusty bread.
    Love kitchen sanctuary recipes!

    This was so flavorful! I’ve been wanting to eliminate food waste, and this recipe helped with this goal. All of my wrinkly veggies from before my vacation went into this. I served it with a splash heavy whipping cream and crunchy bread.
