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.

🔪 How to make this vegetable soup
***Full recipe with detailed steps in the recipe card at the end of this post***.
- Roast chunks of sweet potato, red and yellow bell peppers, carrot, red onion and garlic (skin on) in the oven with a little olive oil, salt, pepper, paprika and cumin.

- Add a litre of vegetable stock and simmer for 5 minutes
- Blend carefully with a hand blender, then stir in grated parmesan (or vegetarian hard cheese) and a little more seasoning.
Serve topped with the reserved roasted vegetables and a sprinkling of Parmesan and fresh thyme leaves.
👩🍳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.

If freezing I would recommend blending up all of the roasted vegetables, rather than reserving some, as they may go mushy upon defrosting. Nutritional Information is per serving.
