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 the roasted vegetables to a large pan (reserve a few bits to top the soup) and squeeze the garlic out of their skins to add in there too.
- 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.

Notes
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. Nutritional Information is per serving.

I am so happy to have found you
A fab healthy soup recipe… I will make it again but will add some Aleppo pepper for gentle rounded heat along with the paprika and cumin. I didn’t have a yellow pepper (lockdown shopping restrictions) so I used two red peppers. It was a little on the sweet side for us… but that’s personal taste. I might swap a few veggies around next time. I highly recommend the recipe with its amazing nutritional value. Thanks for the recipe and the video. Stay safe…
So healthy and delicious! .Anita
Every recipe I have followed of yours is exquisite. I’ve been my own home chef a long time but you continue to inspire me. Great and comforting work, especially in a global pandemic. Kudos to you, and one and all, Catherine
Absolutely delicious soup. It is one of our family favourites now.
This is always one of my favorite soups, i’ve changed it up with whatever winter squash i have on hand, added fresh roasted tomatoes, or canned fire roasted. i even added kale and chickpeas to it after i blended it this time. So versatile!
What a delicious bowl of comforting soup, roasting the veg definitely made for a deeper flavour.
I love roasted veggie soup. I make one similar. Instead of sweet potatoes I use roasted tomatoes and I add roasted garlic. My family loves it. Can’t wait to try it with sweet potatoe!
This recipe is SO me. Roasted veggies and cheese are two of my main food groups.
Thanks Annie – I’ve just been drooling over your honey ricotta pancake too 🙂
