Step‑by‑Step Instructions for Roasted Vegetable Soup

Step 1: Preheat the Oven
Begin by preheating your oven to 175°C (350°F) using the fan-assisted setting. This temperature ensures that the vegetables roast evenly, developing a rich and flavorful foundation for your Roasted Vegetable Soup. While the oven is heating, gather your ingredients and tools, including a large baking tray, a cutting board, and a sharp knife.

Step 2: Prepare the Vegetables
Next, chop the onions, peppers, tomatoes, sweet potatoes, and carrots into chunky, even-sized pieces. This uniform size helps them roast evenly and enhances the overall texture of the soup. Aim for a rustic cut that showcases the vibrant colors of your seasonal produce, creating a beautiful medley for the Roasted Vegetable Soup.

Step 3: Toss the Vegetables
In your large baking tray, combine the chopped vegetables with extra virgin olive oil, dried sage, Italian herbs, salt, and pepper. Use your hands to ensure every piece is coated well, which promotes even roasting and flavor absorption. Add whole garlic cloves with their skins on and sprinkle the fresh rosemary on top to infuse the dish with aromatic notes.

Step 4: Roast the Vegetables
Spread the vegetable mixture evenly in the baking tray and place it in the heated oven. Roast for about 25 minutes, then stir the vegetables to ensure even cooking. Continue roasting for an additional 20-25 minutes, or until they are golden brown and fork-tender. The fragrant aroma will fill your kitchen, promising a delightful Roasted Vegetable Soup.

Step 5: Remove the Garlic Skins
Once the vegetables are perfectly roasted, carefully remove the tray from the oven and let it cool slightly. Remove the roasted garlic from its skins, which will be soft and sweet. Add both the roasted vegetables and the peeled garlic into a deep saucepan, preparing to blend them into a smooth base for your soup.

Step 6: Blend the Mixture
Pour in your vegetable stock to the pan with the roasted vegetables and garlic. Using a hand blender, blend the mixture until creamy and smooth, ensuring no chunks remain. This step is essential for achieving that velvety texture that makes your Roasted Vegetable Soup comforting and satisfying.

Step 7: Stir in Cream and Season
Once blended, stir in your choice of cream, adjusting the richness to your taste. Give the soup a good mix and taste for seasoning, adding more salt and pepper if needed. This final touch enhances the flavors, ensuring each spoonful of the Roasted Vegetable Soup is absolutely delicious.

Step 8: Serve and Garnish
Ladle the creamy soup into warm bowls and garnish with freshly chopped parsley or chives for a pop of color. Drizzle a little extra virgin olive oil over the top for added richness and flavor. Pair with crusty bread for a delightful meal, making this Roasted Vegetable Soup even more enjoyable.
