Tips & Variations
- For extra depth, try roasting the vegetables at a slightly higher temperature for the last 5 minutes to deepen caramelization.
- Swap rosemary with fresh thyme or oregano for a different herbal note.
- Add a pinch of smoked paprika or chili flakes to give the soup a subtle smoky or spicy kick.
- Use coconut cream instead of single cream to make the soup vegan and add a mild coconut flavor.
Storage
