- Blend thoroughly – For a creamy consistency, blend the soup until completely smooth, leaving no chunks behind.
- Adjust seasoning – Taste and adjust salt, pepper, and herbs at the end for optimal flavor balance.
- Store properly – Keep leftovers in airtight containers in the fridge for up to three days; reheat gently on the stove.

Common Mistakes to Avoid
When making roasted vegetable soup, it’s easy to overlook some crucial steps. Here are common mistakes and tips to ensure your soup turns out perfectly.
- Flavoring: Forgetting to season your vegetables can lead to bland soup. Always add salt and pepper before roasting to enhance the flavors.
- Correct Roasting Temperature: Roasting at too low a temperature won’t caramelize the vegetables properly. Aim for at least 200°C (400°F) for optimal results.
- Overcrowding the Pan: Placing too many vegetables on a single tray can steam them instead of roasting. Use multiple trays or roast in batches for better caramelization.
- Skipping the Blend: Not blending the soup thoroughly may result in a chunky texture. For a creamy consistency, blend until smooth and consider adding cream gradually.
- Timing Adjustments: Cooking for too long can cause the vegetables to lose their flavor. Keep an eye on them and test for doneness around the 30-minute mark.

Storage & Reheating Instructions
Refrigerator Storage
- Store leftover roasted vegetable soup in an airtight container.
- It will keep well for up to 4 days in the refrigerator.
Freezing Roasted Vegetable Soup
- Let the soup cool completely before transferring it to freezer-safe containers.
- You can freeze it for up to 3 months; just make sure to label each container with the date.
Reheating Roasted Vegetable Soup
- Oven: Preheat your oven to 180°C (350°F) and heat in an oven-safe dish for about 20 minutes or until warm throughout.
