Drizzle with single cream and season with salt and pepper to enhance their flavors. The cream will add a luscious touch to your soup.
Sprinkle fresh rosemary over the top. This fragrant herb will infuse the vegetables with its lovely aroma as they roast in the oven.
Roast in the oven for about 25-30 minutes or until the vegetables are tender and slightly caramelized. This creates a rich base for your soup.
Blend the roasted veggies with a bit of vegetable broth until smooth. You can adjust the consistency by adding more broth if you prefer a thinner soup.
