This roasted vegetable soup is the perfect meal for chilly weather; it’s rich in flavour with a soothing and creamy texture that we just love.
Roasting the vegetables first allows them to caramelise and intensifies the flavour, which is something you don’t get from boiling or sautèing (that’s why our roasted red pepper soup is so popular).
I also love that you can toss everything in a roasting tray and get on with other things while it cooks, so it’s fairly low prep.
The veg is then blended with stock for a thick and creamy soup that is so rich in flavour, it’s simple, wholesome and perfect for using up leftover veggies.

Pin It- Red onion – you can also use white or brown onion instead.
- Leek – I love the flavour of leeks, but if you don’t have one, you can add another onion to the roasting tray instead.
- Thyme – rosemary would be a great alternative, as would dried oregano.
- Butternut squash – you can use another similar squash, such as honeynut or pumpkin.
- Pecorino – We used Pecorino Toscano, which is a semi-hard cheese with a delicious nutty flavour. It’s a lot less salty than Pecorino Romano, but that would work as a good alternative, as would Parmigiano Reggiano.
Recipe tips and FAQs
- Cutting the veg – cut the vegetables into roughly the same-sized chunks to ensure they roast evenly.
- Roast the veg to perfection – you’ll know the veg is done when they are slightly charred around the edges (this adds so much flavour). It usually takes 45 minutes to 1 hour.
- Adjusting consistency – if, after blending, your soup is too thick, you can adjust the consistency with more water or stock. Add a little at a time and stir it in to avoid adding too much.
- Use low-sodium stock – if you are not using homemade, then I recommend using a low-sodium, good-quality stock so you can adjust the amount of salt added afterwards.
Yes, you can prep the soup in advance or just simply roast the veg in advance. The soup will keep well in the fridge for up to 3 days.
Yes, freeze the soup in suitable containers for up to 3 months.
Yes, you can saute the leek, onion and garlic together until soft, then add in all the other chopped veg and stock. Simmer the soup until the veg is cooked through, then blend. Note that the flavour won’t be as rich as when it’s roasted.

Easy Roasted Vegetable Soup
Ingredients
- 1 red bell pepper
- 1 lb (450g) Butternut squash, (about 2.5 cups)
- 1 leek
- 1 red onion
- 1 small/medium eggplant (aubergine)
- 5 cloves of garlic
- 4 1/4 cups (1 litre) vegetable stock
- 3-4 sprigs thyme leaves, plus extra for garnish
- 5 tablespoons olive oil
- Pecorino Toscano cheese, for serving (optional)
- Salt and pepper
Instructions
- Preheat the oven to 180°C(350°F) fan 200℃(400℉) static.
- Using a knife, remove most of the eggplant skin (it doesn’t need to be perfect). Roughly chop the squash, eggplant, red pepper and red onion into medium-sized pieces and add to a baking tray. Add the thyme leaves and garlic and season well with salt and pepper. Drizzle with around 4 tablespoons of olive oil, and rub the oil all over the veg.
- Roast the vegetables in the oven for 45 minutes to 1 hour until slightly golden and cooked through.
- Wash and finely slice the leek. Add 1 tablespoon of olive oil to a large pot under a low/medium heat and sauté the leek until soft but not browned.
- Remove the garlic from the tray and let them cool. Add the cooked roasted vegetables to the pot, then when cool enough to touch, squeeze the roasted garlic from their skins into the pot.
- Add the vegetable stock, and simmer the soup for 15 minutes. Blitz the soup until smooth with an immersion or regular blender (be careful when blitzing hot soup).
- Check for seasoning and add more salt and pepper as needed, then serve in bowls topped with grated pecorino cheese and more thyme for garnish.

In the ingredient list it doesn’t mention red onion but in the instructions it does. How much do you need? Thanks
Oh so sorry Heather, I hadn’t noticed that mistake. You need 1 red onion for the recipe. I’ll amend it asap. Thank you.
