How to Make Roasted Vegetable Soup: Smooth and Creamy
Step 1: Preparing and Roasting the Vegetables
Start by preheating your oven to 175°C FAN / 350°F to get it ready for that perfect roast. Then, gather all your vegetables and place them on a large, deep baking tray. Drizzle with extra virgin olive oil to help the roasting process bring out the natural sugars and flavors. Don’t forget to keep the garlic cloves in their skins—this little trick ensures they soften and mellow beautifully. Sprinkle in the dried sage, Italian herbs, salt, and pepper, then toss everything thoroughly with your hands to make sure every piece gets coated evenly. Finally, lay the rosemary sprigs on top and pop the tray into the oven.
Step 2: Caramelizing the Flavors
After about 25 minutes, take out the tray and stir the vegetables gently to help them cook evenly. This step encourages a beautiful caramelization on every side, which is the secret to the soup’s deep, roasted flavors. Return the tray to the oven for another 20-25 minutes or until the vegetables look golden and tender. This slow roasting is what builds the body and rich character that make this Roasted Vegetable Soup: Smooth and Creamy so unforgettable.
Step 3: Blending into Creamy Perfection
Once the veggies are perfectly roasted, carefully remove the rosemary sprigs and peel the roasted garlic cloves—their flesh will be silky soft and fragrant. Transfer the entire tray content into a deep saucepan or large bowl, pour in the vegetable stock, and use a hand blender to blend everything together until smooth and silky. This is where that signature “smooth and creamy” texture comes to life. Stir in the single cream for extra richness, then taste and adjust the seasoning with salt and pepper as needed.
How to Serve Roasted Vegetable Soup: Smooth and Creamy

Garnishes
The finishing touches make a difference! Sprinkle freshly chopped parsley or chives on top for a burst of color and freshness. A drizzle of extra virgin olive oil or a swirl of cream can elevate the presentation and add a luscious mouthfeel. For a bit of crunch, toasted pumpkin seeds or croutons work wonderfully against the smooth texture.
Side Dishes
This Roasted Vegetable Soup: Smooth and Creamy pairs beautifully with crusty artisan bread, warm garlic focaccia, or even a cheesy grilled sandwich. A simple green salad tossed with lemon vinaigrette offers a refreshing contrast that lightens the meal without competing with the soup’s deep flavors.

FAQs
Can I use other vegetables in this soup?
