Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
1 large head of cauliflower, cut into florets
2 tablespoons olive oil
1 medium onion, chopped
4 cloves garlic, minced
4 cups vegetable broth
1 cup heavy cream
1 teaspoon dried thyme
Salt, to taste
Black pepper, to taste
Fresh parsley, for garnish
Directions
-
Preheat your oven to 400°F (200°C).
-
Spread the cauliflower florets on a baking sheet. Drizzle with olive oil and season lightly with salt and pepper. Toss to coat evenly.
-
Roast for 25 to 30 minutes, or until the cauliflower is tender and golden brown around the edges.
-
In a large pot, sauté the chopped onion over medium heat until soft and translucent, about 5 minutes. Add the minced garlic and cook for another minute until fragrant.
-
Add the roasted cauliflower to the pot along with the vegetable broth and dried thyme. Bring to a gentle boil, then reduce heat and simmer for 15 minutes to allow the flavors to blend.
-
Use an immersion blender to puree the soup until smooth and creamy. Alternatively, carefully blend in batches using a countertop blender.
-
Stir in the heavy cream and heat gently without bringing the soup back to a boil.
-
Taste and adjust seasoning with additional salt and pepper as needed.
-
Serve hot, garnished with freshly chopped parsley.

For a dairy-free version, substitute the heavy cream with coconut milk or a plant-based cream alternative.
Add a pinch of nutmeg for a subtle warmth that complements the cauliflower.
Stir in a small amount of grated Parmesan cheese for extra richness.
For a thicker soup, add one small peeled and diced potato to the broth while simmering.
Top with crispy croutons, toasted almonds, or a drizzle of olive oil for added texture.
Storage/Reheating
Store leftover soup in an airtight container in the refrigerator for up to 3 days. Allow the soup to cool completely before storing.
To reheat, warm gently on the stovetop over low to medium heat, stirring occasionally until heated through. If the soup has thickened too much, add a small splash of broth or water to reach your desired consistency.
This soup can also be frozen for up to 3 months. Freeze in individual portions for convenience. Thaw overnight in the refrigerator before reheating.
FAQs
Can I make this soup ahead of time?
Yes, this soup tastes even better the next day as the flavors continue to develop. Simply store it in the refrigerator and reheat when ready to serve.
Can I use frozen cauliflower?
Yes, frozen cauliflower works well. Roast it directly from frozen, adding a few extra minutes to ensure it browns properly.
Do I have to roast the cauliflower?
Roasting adds depth and sweetness, but if you are short on time, you can simmer the cauliflower directly in the broth. The flavor will be milder.
How can I make the soup thicker?
You can reduce the amount of broth slightly or add a small potato while simmering to naturally thicken the soup.
Can I make this soup vegan?
Absolutely. Replace the heavy cream with coconut milk or another plant-based alternative and ensure your broth is vegetable-based.
What herbs pair well with cauliflower soup?
Thyme, rosemary, sage, and even a touch of chives complement the flavor beautifully.
Can I add protein to this soup?
Yes, you can top it with crispy chickpeas or serve it alongside grilled chicken for a more filling meal.
Why is my soup bland?
It may need more salt or a touch more seasoning. Roasting the cauliflower thoroughly also enhances flavor.
Is this soup gluten-free?
Yes, as written, the soup contains no gluten ingredients. Always check your broth to be certain.
Can I serve this soup cold?
While traditionally served warm, it can be enjoyed slightly chilled, though the flavors are most pronounced when served hot.
