- Total Time: 1 hour 10 minutes
- Yield: 4 bowls
Description
This creamy cauliflower soup is silky, flavorful, and ultra-comforting without using any cream. Roasted cauliflower adds richness, while garlic, lemon, and nutmeg deliver deep, balanced flavor. Enjoy a dairy-free or vegetarian option that’s easy to make and perfect for cold nights.
Ingredients
1 large head cauliflower (about 2 pounds), chopped into small florets
3 tablespoons olive oil, divided
1 medium red onion, chopped
2 cloves garlic, minced or pressed
4 cups vegetable broth
2 tablespoons unsalted butter (or ¼ cup soaked cashews for dairy-free option)
1 tablespoon fresh lemon juice (plus more to taste)
Scant ¼ teaspoon ground nutmeg
Salt, to taste
Optional Garnish:
2 tablespoons chopped fresh parsley, green onions, or chives
Reserved roasted cauliflower florets
Instructions
1. Preheat oven to 425°F. Line a large baking sheet with parchment paper if desired. Toss cauliflower florets with 2 tablespoons of olive oil and a pinch of salt. Spread in a single layer and roast for 25–35 minutes, stirring once, until edges are golden and tender.
2. In a large soup pot, heat the remaining 1 tablespoon of olive oil over medium heat. Add chopped onion and ¼ teaspoon salt. Cook for 5–7 minutes until softened and slightly translucent. Stir in garlic and cook for about 30 seconds until fragrant.
3. Pour in the vegetable broth. Set aside a few roasted cauliflower florets for garnish and add the rest to the pot. Increase heat to bring to a simmer, then reduce and let cook gently for 20 minutes to allow flavors to blend.
4. Remove from heat and let cool briefly. Blend the soup in batches until completely smooth (careful not to overfill the blender). Add butter (or soaked cashews) during blending. Then blend in lemon juice and nutmeg. Taste and add more salt or lemon juice if needed.
5. Pour into bowls, top with reserved roasted cauliflower and sprinkle with fresh herbs. Serve warm.
Notes
For a vegan version, substitute butter with ¼ cup soaked raw cashews. Soak cashews in hot water for 30 minutes before blending.
To reduce sodium, use low-sodium broth and adjust added salt to taste.
Soup can be stored in the refrigerator for up to 4 days or frozen for up to 3 months.

Why You’ll Love This Creamy Cauliflower Soup
The magic of roasted cauliflower
What sets this creamy cauliflower soup apart from others is the foundational step of roasting the cauliflower. Instead of boiling or steaming, the florets are tossed with olive oil and roasted until golden and tender. This caramelization brings out cauliflower’s nutty sweetness and adds a complex depth that can’t be replicated through other methods. Even a small batch of roasted florets reserved for garnish becomes a highlight on the bowl, adding texture and toasty flavor.
Silky texture without heavy cream
Despite its indulgent mouthfeel, this soup contains no cream at all. The magic lies in blending the roasted cauliflower with vegetable broth and a touch of either butter or soaked cashews. Both options provide richness, but the cashews also make it a fully vegan-friendly recipe without sacrificing creaminess. The soup is blended until utterly smooth—no graininess, no lumps, just a velvety consistency that coats the spoon and warms you from within.
Flavor layers that develop as it simmers
Each component in this cauliflower soup builds flavor. Red onion and garlic are gently sautéed in olive oil, then simmered with roasted cauliflower and savory broth. A hint of ground nutmeg adds subtle warmth, while fresh lemon juice brightens the entire dish at the very end. These thoughtful layers make a simple pot of soup taste like something far more elaborate.
Ingredients That Make This Cauliflower Soup Stand Out
The role of aromatics in building base flavor
Start with the basics: a red onion and fresh garlic. While they may seem humble, these aromatics are the quiet heroes that create a savory foundation for your soup. Sautéing the onion slowly until translucent draws out its natural sweetness, setting the stage for everything that follows. When garlic joins the pot for that final 30 seconds, its fragrance instantly deepens the profile and enhances every bite.
Choosing between butter and cashews for creaminess
The creaminess in this recipe comes from your choice of either unsalted butter or soaked cashews. Butter gives the soup a silky, luxurious body that’s instantly familiar, while cashews offer a plant-based richness with no dairy involved. Simply soak raw cashews in warm water for about 30 minutes and blend them directly into the soup. Both options deliver a smooth, satisfying texture—so go with what suits your dietary needs or mood.
Nutmeg and lemon: the secret flavor duo
Nutmeg might seem like a spice reserved for baked goods, but here it adds just the right touch of warmth and complexity. Used sparingly, it enhances the natural richness of the cauliflower without overpowering it. Meanwhile, lemon juice lifts the soup with acidity, balancing out the earthy tones and rounding off the flavor beautifully. Don’t skip that final squeeze—your bowl will thank you.
Step-by-Step: How to Make Creamy Cauliflower Soup
Roasting for depth and richness
Start by prepping your cauliflower. One large head, chopped into small florets, gets tossed in olive oil and lightly salted before roasting. Spread them in a single layer and let the oven work its magic. At 425°F, they’ll transform in just over half an hour—edges turning golden brown, the interior tender and sweet. This step is essential for creating that deep, roasted flavor that makes the soup taste far more decadent than it really is.
Simmering to meld flavors
While your cauliflower roasts, begin your stovetop prep. In a large pot, sauté the red onion in olive oil until it’s soft and fragrant. Garlic joins the mix for just a moment before you pour in the vegetable broth. Add the roasted cauliflower (minus a few florets for garnish) and let everything simmer gently for 20 minutes. This allows all the ingredients to marry together, infusing the broth with a richness that comes only from time and care.
Blending to creamy perfection
Once your soup has simmered and cooled slightly, it’s time to blend. Do this in batches to avoid overfilling your blender. Add butter or soaked cashews directly to the blender for a silky, luxurious finish. Finally, blend in fresh lemon juice and a dash of nutmeg. The result is a flawlessly smooth, creamy cauliflower soup that’s as satisfying as it is nourishing.
Smart Substitutions and Dietary Tips
How to make it vegan or dairy-free
With one simple substitution, this recipe easily becomes vegan. Swap out the butter for soaked cashews and stick with vegetable broth, and you’ve got a plant-based creamy cauliflower soup that doesn’t compromise on taste or texture. The cashews add healthy fats and creaminess while keeping the soup entirely dairy-free.
Boosting protein without changing the flavor
If you’re looking to add more protein, stir in a scoop of unflavored plant-based protein powder before blending, or top each bowl with roasted chickpeas. These additions blend seamlessly into the soup and won’t disrupt the delicate flavors. A handful of cooked lentils also makes a great add-in, especially if you’re enjoying this as a full meal.
How to adjust for low sodium diets
To reduce sodium, choose a low-sodium vegetable broth and go easy on added salt during cooking. Roasting the cauliflower enhances its flavor naturally, so you won’t miss the saltiness. A finishing squeeze of lemon juice also tricks the palate into perceiving more depth, helping compensate for the reduced salt.
Serving Ideas for Creamy Cauliflower Soup
Garnish and topping inspiration
Elevate each bowl with thoughtful toppings. Those reserved roasted cauliflower florets make the perfect golden garnish. Add a sprinkle of chopped fresh herbs like parsley or chives for color and freshness. For texture, consider toasted seeds, crispy croutons, or even a swirl of chili oil for heat.
What to serve on the side
Pair your soup with crusty sourdough, a toasted baguette, or a grilled cheese sandwich for the ultimate comfort combo. For a lighter side, a simple green salad with vinaigrette balances the soup’s richness beautifully. It’s also perfect as a first course for meals featuring roasted chicken or baked tofu.
How to store and reheat leftovers
This soup keeps beautifully in the fridge for up to four days. Reheat gently on the stove or in the microwave, adding a splash of water or broth if it thickens too much. It also freezes well—just let it cool fully before storing in airtight containers. Thaw overnight in the fridge before reheating.
More Soul-Warming Soups to Try
If this recipe warms your heart, there’s more where it came from. On chilly nights, few things satisfy like a steaming bowl of classic vegetable soup. It’s a timeless staple, brimming with wholesome ingredients and homey flavor.
Or for something with a little exotic flair, try the Thai coconut soup. It’s vibrant, aromatic, and offers a spicy-sweet contrast to this creamy cauliflower version. Both are excellent ways to keep soup season fresh and exciting.
Don’t be afraid to experiment—these soups are endlessly adaptable and always welcome at the table.
FAQs About Creamy Cauliflower Soup
How to make cauliflower soup taste better?
Roasting the cauliflower before blending is the single best way to intensify flavor. Also, be generous with aromatics like onion and garlic, and finish with fresh lemon juice to brighten the final dish. A sprinkle of herbs or a drizzle of flavored oil can also elevate your bowl instantly.
Do you put milk in cauliflower soup?
Traditional recipes often call for milk or cream, but this one skips both without sacrificing creaminess. Thanks to blended roasted cauliflower, butter (or cashews), and broth, the texture is already rich and silky—no dairy required.
Can you freeze creamy cauliflower soup?
Yes! This soup freezes very well. Store it in freezer-safe containers for up to 3 months. Let it thaw overnight in the fridge and reheat gently, adding broth or water as needed to reach the desired consistency.
Why is my cauliflower soup grainy?
Graininess usually comes from undercooked cauliflower or insufficient blending. Make sure the roasted florets are tender before simmering, and blend thoroughly in batches until completely smooth. A high-speed blender also helps achieve that ultra-silky texture.
