How to Make Roasted Vegetable Soup
Step 1: Preheat the Oven
Preheat your oven to 200°C (400°F). This ensures that your vegetables roast evenly and develop that wonderful caramelization.
Step 2: Prepare the Vegetables

- Drizzle with olive oil, then sprinkle salt, pepper, dried sage, and Italian herbs over the top.
- Toss everything together until well coated.
Step 3: Roast the Vegetables
Place the tray in the preheated oven and roast for about 30 minutes. Stir halfway through to ensure even cooking until they are tender and caramelized.
Step 4: Blend the Soup
Once roasted, transfer all vegetables into a large pot along with vegetable stock and fresh rosemary.
1. Bring to a simmer over medium heat.
2. Use an immersion blender to puree until smooth; alternatively, transfer in batches to a regular blender.
Step 5: Add Cream & Serve
Stir in the single cream for added richness. Taste and adjust seasoning if necessary before serving hot with crusty bread or croutons.

Common Mistakes to Avoid
Making roasted vegetable soup can be a delightful experience, but it’s easy to make mistakes that can affect the final dish.
- preparation: Skipping the step of properly cutting vegetables can lead to uneven cooking. Make sure to cut vegetables into similar sizes for consistent roasting.
- seasoning: Under-seasoning your soup can result in bland flavors. Be generous with salt, pepper, and herbs to enhance the taste.
- blending: Not allowing your roasted vegetables to cool before blending can cause splattering. Let them cool for a few minutes to ensure a smooth puree.
- storage: Forgetting to store leftover soup properly may lead to spoilage. Use airtight containers and label them with dates for safe storage.
- timing: Rushing the roasting process will not allow the vegetables to caramelize fully. Take your time and roast until they are golden brown for maximum flavor.
