FAQs

Why should vegetables be roasted before making vegetable soup?

Roasting vegetables brings out their natural sweetness and adds depth through caramelisation. This step creates a richer, more complex flavour than boiling alone, which is why roast vegetable soup tastes fuller and more satisfying.

How do I stop roast vegetable soup from tasting bitter?

Bitterness usually comes from over-roasted or burnt vegetables, especially garlic or peppers. Roast until golden, not dark brown, and discard any overly charred pieces before blending to keep the flavour balanced.

Why is my roast vegetable soup too thick after blending?

Roasted vegetables are naturally dense and absorb liquid easily. If the soup feels too thick, add hot stock gradually after blending until it reaches a smooth, pourable consistency.

Can I make roast vegetable soup ahead of time?

Yes, this soup is ideal for making ahead. The flavours actually improve after resting. Store it in the fridge for up to 3 days and reheat gently, adding a splash of stock if it thickens.
