Cauliflower soup recipe can be creamy without a splash of heavy cream. Roasting cauliflower gives it golden edges and a deeper, slightly nutty flavor; blending those tender pieces into vegetable broth creates a smooth, velvety bowl. This version uses garlic, shallots, fresh thyme, white miso, Dijon mustard and lemon to build flavor without milk or cheese. For broader guidance on balancing herbs in vegetable broths, read Vegetable Soup Seasoning; this cauliflower soup already includes several savory ingredients, so additional herbs are optional.
Quick answer: Roast a roughly 2-pound head of chopped cauliflower with shallots and garlic at 400°F (205°C) for about 30–35 minutes. Simmer the roasted vegetables in 4 cups vegetable broth with thyme for 15 minutes. Let cool slightly, then blend with olive oil, a little white miso, Dijon mustard and fresh lemon juice. This is a research-based editorial adaptation of Love and Lemons’ Cauliflower Soup, which reports six servings and approximately an hour total.

Why This Cauliflower Soup Recipe Works Without Cream
Cauliflower softens as it cooks and blends into a naturally thick puree. Roasting it first adds browned flavor that boiling alone does not produce. Shallots and garlic contribute a mild aromatic base, while miso adds savory depth, mustard brings tang and lemon brightens the finished soup. Using vegetable broth instead of dairy also keeps the recipe’s core method straightforward.
Although our Creamy Vegetable Soup also skips heavy cream, it gets much of its body from blended potatoes and includes carrots, peas, corn and milk. Here, cauliflower is the main vegetable and the entire soup is blended smooth. For a lighter soup that keeps broccoli and cauliflower in identifiable pieces, compare Vegetable Soup Without Tomatoes.
Cauliflower Soup Recipe Ingredients
- 1 medium cauliflower (about 2 pounds): Include the tender core as well as florets. Cut into fairly even pieces so they roast at similar speeds.
- 2 shallots and 4 garlic cloves: Roast these together; leave the garlic unpeeled until it softens.
- 4 cups vegetable broth: A lower-sodium broth makes it easier to season the finished soup.
- Fresh thyme leaves from about 5 sprigs: Adds an earthy, savory flavor.
- 3 tablespoons extra-virgin olive oil, plus a little for the aromatics: Helps the vegetables brown and makes the blended texture silky.
- ½ tablespoon white miso paste: Provides umami. Miso often contains soy, so check labels when necessary.
- ½ teaspoon Dijon mustard: A small amount adds balance without turning the soup into mustard soup.
- 1 tablespoon lemon juice: Add near the end and adjust carefully to taste.
- Sea salt and black pepper: Season to taste. Optional microgreens or chopped chives can garnish each bowl.
Choose the exact ingredients listed if you want the plant-based preparation described here. Do not add milk, cream, cheese or a butter-based topping and then describe that modified batch as dairy-free.
How to Make Cauliflower Soup: Roast, Simmer, Blend
- Heat the oven and prepare the tray. Set the oven to 400°F (205°C) and line a large rimmed baking sheet. Cut the cauliflower into evenly sized florets and core pieces. Toss with some olive oil, salt and pepper, then spread into a single layer.
- Roast the aromatics alongside. Wrap the quartered shallots and unpeeled garlic cloves with a small drizzle of oil in a foil packet. Put it on the same tray as the cauliflower. Roast for about 30–35 minutes, until the cauliflower is tender with browned edges and the aromatics are soft.
- Simmer briefly. Warm vegetable broth in a large saucepan or Dutch oven. Squeeze the roasted garlic from its skins and add it to the broth with the shallots, cauliflower and fresh thyme leaves. Simmer gently, covered, for about 15 minutes.
- Blend safely. Remove the pot from the heat and let it cool a little. Puree with an immersion blender, or transfer to a heat-rated countertop blender in small batches, following the manufacturer’s hot-liquid safety instructions.
- Season and serve. Blend in the remaining olive oil, white miso, Dijon mustard and lemon juice. Taste before adding more salt or pepper. Ladle into warm bowls and add microgreens or chopped chives if desired.

Ingredients
Method
- Heat the oven to 400°F (205°C). Spread chopped cauliflower on a parchment-lined sheet pan. Toss lightly with olive oil, salt and pepper. Put the shallots and unpeeled garlic cloves with a little oil in a loosely sealed foil packet on the same tray. Roast until the cauliflower is tender and deeply golden at the edges, about 30–35 minutes.
- Heat vegetable broth in a large soup pot. Add roasted cauliflower, the tender shallots, peeled roasted garlic and thyme leaves. Maintain a gentle simmer, covered, for about 15 minutes.
- Allow the soup to cool slightly. Blend in batches in a heat-rated countertop blender, never overfilling, or use an immersion blender in the pot.
- Add the remaining olive oil, white miso, Dijon mustard and lemon juice while blending until velvety. Taste and season with salt and pepper. Thin with a little additional warm broth only if needed.
- Ladle warm soup into bowls and top with microgreens or chopped chives if desired. Refrigerate any leftovers promptly.
Notes
How to Get a Smooth, Velvety Texture
The cauliflower should be completely tender before you blend. Hard pieces remain grainy, so check a thick stem with a fork. Blend in batches for long enough to break down the cauliflower and shallots. If the soup seems too thick for your blender or spoon, add a little warm broth at a time. If it is thinner than you prefer, return it to a gentle simmer briefly so excess liquid can evaporate; watch for splashes.
For a more rustic texture, pulse rather than fully puree, though that changes the smooth version described in the recipe card. Roasted cauliflower florets can also be reserved as a topping. Do not fill a countertop blender above its maximum hot-liquid line, and never seal a non-vented container full of very hot soup.
Does Cauliflower Soup Have to Use Milk or Cream?
No. The reference method depends on roasted, blended cauliflower for most of its body. The recipe is dairy-free as written, provided the broth, miso and other purchased ingredients are compatible with your dietary needs. Different soup recipes use milk, cream, butter or cheese, but those are alternative preparations rather than ingredients required here.
If you want to make a different creamy cauliflower soup with butter, Cookie and Kate’s Creamy Roasted Cauliflower Soup uses a small amount of butter without heavy cream. That is a separate recipe with different seasonings and serving quantities, not a tested swap for this article.
Best Toppings and Serving Pairings
Simple toppings make the pale blended soup more appealing: chopped chives, microgreens, fresh thyme leaves, toasted seeds or a small amount of reserved roasted cauliflower. Choose toppings that fit your dietary needs. For a light meal, pair the soup with crusty bread or a green salad.
For readers building a vegetable-centered table, our Dips for a Vegetable Tray collection offers cold appetizers that can be served before the soup. The soup itself is a separate course, not a dipping sauce for a veggie tray.
Make-Ahead, Storage and Reheating
- Make ahead: The roasted cauliflower and aromatics may be prepared before the final blending step. Refrigerate cooked components promptly and finish the recipe when ready.
- Refrigerate: Cool in shallow containers and refrigerate promptly at 40°F (4°C) or lower. The Love and Lemons recipe suggests up to about 4 days in the refrigerator for properly stored soup.
- Freeze: The source suggests freezing the soup for up to 3 months. Use a freezer-safe container with expansion space and thaw in the refrigerator.
- Reheat: Rewarm gently in a saucepan, stirring and adding a small amount of broth if the texture has thickened.
- Safety: Follow FoodSafety.gov guidance for storing hot food promptly and reheating leftovers thoroughly.
Cauliflower Soup vs. Our Other Vegetable Soups

Frequently Asked Questions
Can I make cauliflower soup without heavy cream?
Yes. Roast the cauliflower until tender, then blend it with vegetable broth and aromatics. This recipe uses olive oil, miso, mustard and lemon for flavor and does not require cream or milk.
Do I need to roast cauliflower first?
For this version, yes: roasting is central to the deeper browned flavor. Steaming or boiling cauliflower is a different method and may produce a milder result.
Can I make cauliflower soup without miso?
You can omit miso as an adaptation if you cannot use it, but it adds a savory note and the result will taste different. Taste carefully before replacing it with extra salt; this version without miso has not been independently tested by Vegetable Dips.
Is this soup vegan or gluten-free?
The recipe is plant-based as written. For gluten-free needs, verify the white miso, vegetable broth, mustard and all packaged ingredients, as formulations differ. This is not a medical or allergen guarantee.
Can I use frozen cauliflower?
Frozen cauliflower is a possible adaptation, but thawing and moisture can change the browning and roasting time. The referenced recipe specifies fresh cauliflower, and we have not tested a frozen version.
How do I prevent watery cauliflower soup?
Start with the stated amount of broth, blend thoroughly once the cauliflower is soft, and adjust with additional warm broth only if the finished soup needs thinning. If you want more concentrated texture, simmer gently to reduce it.
