Cream of vegetable soup is a comforting, beginner-friendly stovetop meal made with tender vegetables, savory chicken broth, herbs, and heavy cream. Blending everything together gives the soup a silky finish while keeping the fresh vegetable flavors at the center.
This is the kind of soup that works beautifully when you want something warm and satisfying without spending hours in the kitchen. Most of the cooking happens in one pot, and the vegetables only need a short simmer before they are ready to blend.
The combination of carrots, sweet potato, celery, zucchini, red onion, and garlic gives the soup a naturally rounded flavor. Sweet potato provides subtle sweetness and body, while zucchini keeps the finished texture lighter and smoother.
A small amount of herbes de Provence adds an aromatic background without overpowering the vegetables. Once heavy cream is stirred into the purée, the soup becomes wonderfully smooth and rich enough for a cozy lunch, simple dinner, or starter.
Ingredients
You only need a straightforward collection of vegetables and pantry staples to prepare this creamy blended soup.
- Red onion: Creates the aromatic base and develops a mild sweetness as it softens in olive oil.
- Garlic: Adds savory depth without dominating the delicate vegetable flavors.
- Extra-virgin olive oil: Used to sauté the aromatics and vegetables before the broth goes into the pot.
- Celery: Contributes a subtle savory flavor that balances the sweeter vegetables.
- Carrots: Add color, mild sweetness, and body once blended.
- Sweet potato: Helps naturally thicken the soup and gives the purée a smooth consistency.
- Zucchini: Adds another layer of vegetable flavor while blending easily into the soup.
- Chicken broth: Provides the liquid base and gives the vegetables a fuller savory flavor.
- Herbes de Provence: Adds a gentle blend of dried herbs that works particularly well with the vegetables and cream.
- Heavy cream: Gives the finished soup its rich, silky texture.
- Salt and black pepper: Bring the vegetable and herb flavors together.
Cooking Steps
STEP 1: Heat the olive oil in a large soup pot over medium-high heat. Add the chopped red onion and minced garlic, then cook for about 5 minutes. Stir occasionally so the garlic does not brown too quickly. The onion should become soft and translucent.
STEP 2: Add the chopped celery and roughly diced carrots. Continue cooking for approximately 5 minutes. This brief sauté gives the firmer vegetables a head start and helps build more flavor before the broth is added.
STEP 3: Stir the cubed sweet potato into the vegetables. Pour in the chicken broth and increase the heat until the liquid reaches a boil. Lower the heat and maintain a gentle simmer for about 15 minutes, or until the carrots and sweet potato are easily pierced with a fork.
STEP 4: Add the zucchini pieces only after the firmer vegetables are nearly tender. Let everything simmer for another 5 minutes. Zucchini cooks much faster than carrots or sweet potato, so adding it toward the end prevents unnecessary overcooking.
STEP 5: Stir in the herbes de Provence and season with salt and freshly ground black pepper. Use an immersion blender to carefully purée the vegetables and broth directly in the pot. Continue blending until there are no obvious vegetable pieces remaining.
STEP 6: Pour the heavy cream into the blended soup and stir well. Blend briefly once more to fully incorporate the cream and create an especially smooth consistency. Taste before serving and adjust the salt or pepper if necessary. Ladle into bowls while hot.
Recipe Tips
- Check the firm vegetables before blending. The carrots and sweet potato should be completely tender. Vegetables that are still firm can leave the soup slightly grainy rather than velvety.
- Blend longer for a finer texture. Once the large pieces disappear, continue blending for another short interval if you prefer a restaurant-style smooth finish.
- Add the cream after puréeing. Blending the cooked vegetables first makes it easier to judge the consistency before the heavy cream is incorporated.
Can I use a regular blender instead of an immersion blender?
Yes. Allow the soup to cool slightly, then carefully transfer it to a countertop blender in batches. Avoid filling the blender completely with hot liquid, and make sure steam can escape safely. Blend until smooth, return the soup to the pot, and then stir in the cream.
Why is my vegetable soup not completely smooth?
The most common reason is that the carrots or sweet potato were not cooked until fully tender. Letting the vegetables simmer until they can be pierced very easily makes blending much more effective. A few additional minutes of blending can also noticeably improve the texture.
Perfect Pairings
Because this soup has a smooth texture and relatively gentle vegetable flavor, sides with a little contrast work especially well.
- Crusty bread: A thick slice of toasted bread is ideal for dipping into the creamy soup and makes a simple bowl feel more substantial.
- Green salad: A crisp salad provides a fresh contrast to the warm, blended vegetables and rich cream.
- Grilled sandwich: Pair the soup with a toasted cheese or simple savory sandwich when you want to turn it into a heartier lunch or weeknight dinner.
Can I prepare the soup ahead of time?
Yes. This is a convenient make-ahead soup because the flavors remain enjoyable after chilling. Prepare and blend it as directed, cool it promptly, and refrigerate it in a covered container. Reheat gently on the stovetop when you are ready to serve.
Can I change the thickness?
Absolutely. The sweet potato naturally gives the soup some body, so it can become fairly creamy after blending. If you prefer a thinner consistency, stir in a small splash of broth after puréeing. If it seems too thin, simmer it uncovered briefly before adding the cream.
Keeping Leftovers Fresh
Allow leftover soup to cool before transferring it to a tightly covered container. Store it in the refrigerator for up to 3 to 4 days. Because the recipe contains heavy cream, refrigerate leftovers promptly rather than allowing the pot to remain at room temperature for an extended period.
For reheating, place the amount you need in a saucepan over low to medium-low heat. Stir frequently and warm it gently until steaming. Avoid aggressively boiling the soup after the cream has been added, since gentler heating helps maintain the smooth consistency.
You can also reheat individual portions in the microwave. Use short intervals and stir between each one so the center and edges heat evenly.
For longer storage, the vegetable base can be frozen, although cream-based soups can sometimes separate slightly after thawing. For the smoothest freezer-friendly approach, prepare and blend the vegetables without the heavy cream, cool the soup completely, and freeze it for up to 2 to 3 months. Thaw it overnight in the refrigerator, reheat gently, and stir in the cream shortly before serving.
Can I make it without heavy cream?
You can leave out the cream if necessary, although the final soup will be less rich and silky. The blended sweet potato, carrots, and zucchini still give the soup natural body. If omitting the cream, check the consistency after blending and add broth only if it needs thinning.

- 1 garlic clove finely minced
- Fine salt as needed
- Ground black pepper to taste
Instructions
- Warm the extra-virgin olive oil in a large pot over medium-high heat. Add the chopped red onion and finely minced garlic once the oil is hot. Cook for approximately 5 minutes, stirring from time to time, until the onion has softened and become translucent.

- Stir the large zucchini pieces into the simmering soup. Continue cooking for about 5 additional minutes, just until the zucchini becomes tender.
- Add the herbes de Provence, then season with salt and black pepper according to taste.
- Using an immersion blender, carefully purée the soup directly in the pot until the vegetables form a smooth, creamy consistency.
- Pour the heavy cream into the puréed soup and stir until evenly distributed. Blend the soup once more with the immersion blender to completely incorporate the cream and create a silky finish.
