How to Make Creamy Roasted Vegetable Soup Recipe

Step 1: Preheat and Prepare the Oven

Start by setting your oven to 175°C FAN / 350°F. Getting the oven to just the right temperature is important because it allows the vegetables to roast evenly, caramelize beautifully, and develop those irresistible depthful flavors that form the backbone of this soup.

Step 2: Combine and Coat the Vegetables

In a large and deep baking tray, toss together all your sliced vegetables: onions, garlic (skin intact), peppers, sweet potatoes, tomatoes, and carrots. Drizzle over the extra virgin olive oil, then sprinkle the dried sage, Italian herb, salt, and pepper on top. Add your fragrant rosemary sprigs last. Use your hands to mix everything thoroughly. This tactile step ensures the oil and seasonings coat every nook and cranny, helping each vegetable shine in the roasting process.

Step 3: Roast the Vegetables Part One

Place the baking tray in the oven and roast for 25 minutes. During this time, the vegetables will start to soften and the sugars will begin to caramelize, producing those rich, toasty notes that give this soup its unique depth of flavor.

Step 4: Stir and Continue Roasting

After the initial roasting period, give the vegetables a careful stir to promote even cooking and further caramelization. Then, return the tray to the oven for another 25 minutes. By the end, you want everything tender and beautifully golden brown when pierced, which will make blending a breeze and yield a silky result.

Step 5: Blend Into a Creamy Dream

Once your vegetables are perfectly roasted, remove the rosemary sprigs and peel off the softened garlic skins. Transfer the contents into a deep saucepan or bowl, add the vegetable stock, and blend using a hand blender until smooth. This step transforms the mixture into the luscious, creamy texture that makes this Creamy Roasted Vegetable Soup Recipe so inviting and comforting.

Step 6: Finish and Season

Finally, stir in the single cream to enrich the soup, creating a velvety finish. Taste your creation and adjust the salt and pepper as needed. Serve it hot right away and prepare to fall in love with this soul-warming bowl of goodness.

Side Dishes

This soup pairs wonderfully with crusty bread or warm garlic focaccia. A side salad tossed with lemon vinaigrette or a simple grilled cheese sandwich can complement the rustic flavors perfectly, turning your meal into a cozy gathering.

Creative Ways to Present

For a fun twist, serve the soup in hollowed-out mini pumpkins or bread bowls. You can also layer it with a dollop of pesto or a sprinkle of toasted seeds for textural excitement. Don’t be afraid to get creative — this Creamy Roasted Vegetable Soup Recipe is versatile and ready to impress your guests.

Make Ahead and Storage

Storing Leftovers

Leftovers can be stored in airtight containers in the refrigerator for up to 3 days. Keeping it chilled properly preserves the flavors and creaminess without compromising texture.

Freezing

This soup freezes beautifully! Pour cooled soup into freezer-safe containers, leaving some space for expansion. It will keep well for up to 3 months, making it a fantastic option for meal prep or busy nights when you need a comforting meal on hand.

Reheating

When reheating, gently warm the soup on the stove over low to medium heat, stirring regularly to prevent scorching. You may want to add a splash of vegetable stock or cream if it has thickened too much in the fridge or freezer.

FAQs

Can I use other vegetables for this recipe?

Absolutely! The beauty of the Creamy Roasted Vegetable Soup Recipe is its flexibility. You can swap in zucchini, parsnips, or butternut squash depending on what you have on hand or what’s in season.

Is this soup suitable for vegans?

To make it vegan, simply omit the single cream or replace it with a plant-based cream alternative. The rich roasted flavors will still shine through wonderfully.

Why keep the garlic skin on while roasting?

Roasting garlic with the skin on mellows its sharpness and adds a subtle, sweet depth of flavor, which enhances the entire soup’s taste without any bitterness.

Can I prepare this soup without an oven?

While roasting deepens flavors, you can sauté the vegetables on the stove until soft and caramelized, then proceed with blending for a quicker, albeit slightly different version.

How thick should the soup be?

The soup should be smooth and creamy but not too thick to sip easily. If it becomes too dense after blending, simply thin it with a bit more vegetable stock or water to your desired consistency.
