Ingredients You’ll Need

12 cups cauliflower florets (about 1½ large heads, 900 g): This versatile vegetable forms the soup’s base, contributing creaminess and nutrients. You can substitute broccoli if desired.
4 whole garlic cloves, peeled: Roasting the garlic mellows its sharpness, adding a sweet undertone. Whole cloves can be replaced with minced garlic, but reduce the amount for milder flavor.
¼ cup olive oil (60 ml): A good-quality olive oil enhances richness while helping the cauliflower roast perfectly. Avocado oil works as a substitute too.
1 tbsp kosher salt (15 g): Balances flavors and enhances the natural sweetness of the cauliflower. Sea salt can be used if needed.
¾ tsp coarse ground black pepper (2 g): Provides a slight kick without overpowering the dish. Freshly ground black pepper is always a great choice.
⅛ cup olive oil (30 ml) for sautéing: This is used to cook the onions, adding depth. It could also be replaced with butter for a richer flavor.
1 medium yellow onion, diced: This ingredient brings sweetness and body to the soup. A white or sweet onion can serve in a pinch.
1 tsp paprika (2 g): Adds warmth and color. Smoked paprika is a fantastic option for a bolder taste.
4 cups low-sodium vegetable broth (960 ml): This keeps the soup light while adding necessary liquid and flavor. Homemade broth or chicken broth can also be used if you’re not vegetarian.
¾ cup freshly shredded white cheddar cheese (85 g): Melts beautifully, creating a rich, creamy texture. You can substitute with a dairy-free cheese for a vegan option.
Fresh parsley for garnish (optional): Provides a pop of color and a fresh flavor burst. Chives or green onions make great alternatives.
Olive oil for garnish (optional): A drizzle adds luxurious richness to the final dish; flavored oils can be a fun twist.

How to Make Roasted Cauliflower Soup

Preheat the Oven: Begin by preheating your oven to 425°F (218°C). This high heat is essential for roasting the cauliflower to achieve that wonderful caramelized flavor.

Prepare the Baking Sheet: Line an oversized rimmed baking sheet with foil and lightly coat it with cooking spray. This will make cleanup a breeze!

Roast the Cauliflower and Garlic: Place the cauliflower florets and whole garlic cloves on the prepared baking sheet. Drizzle them with ¼ cup olive oil and season with 1 tbsp kosher salt and ¾ tsp coarse ground black pepper. Toss everything well to coat, spreading the mixture into a single layer. Roast in the oven for 25 to 30 minutes, tossing every 10 minutes, until the cauliflower is tender and edges are richly caramelized.

Sauté the Onions: While the cauliflower is roasting, heat ⅛ cup olive oil in a large soup pot over medium heat. Add the diced onion and 1 tsp paprika. Cook, stirring occasionally, until the onion softens and becomes translucent, about 5 minutes. This step builds the flavor foundation for your soup.

Blend the Soup Base: Carefully transfer the onion mixture to a blender, along with 4 cups of low-sodium vegetable broth, all the roasted garlic cloves, and about two-thirds of the roasted cauliflower. Secure the lid tightly and blend until the mixture is completely smooth and creamy, working in batches if necessary.

Combine and Heat: Pour the blended cauliflower purée back into the soup pot. Warm the soup over medium heat for 3 to 4 minutes, stirring occasionally. Gradually add the ¾ cup of freshly shredded white cheddar cheese a small handful at a time, stirring until each addition is melted before adding more. This will create that velvety texture we love!

Serve and Garnish: Remove the soup from heat. Ladle it into bowls and garnish with the reserved roasted cauliflower, a sprinkle of chopped parsley, and a drizzle of olive oil if desired. It’s time to enjoy your delightful creation!

Storing & Reheating

Store any leftover roasted cauliflower soup in an airtight container at room temperature for about 2 hours or refrigerate for up to 5 days. For longer storage, freeze the soup in a freezer-safe container for up to 3 months. Reheat gently on the stovetop over low heat, stirring frequently, or microwave in short intervals until warmed through. Note that the texture might thicken slightly when reheating, so feel free to add a splash of vegetable broth to refresh it.

Chef’s Helpful Tips

When roasting, make sure the cauliflower is evenly coated with oil and spread out in a single layer to ensure even cooking.
Use fresh ingredients whenever possible for the best flavor. Fresh herbs make a significant difference.
To enhance the soup’s flavor, consider adding a splash of lemon juice before serving for a bright finish.
If you prefer a chunkier soup, reserve a portion of the roasted cauliflower to stir in after blending.
Make ahead! You can roast the cauliflower and prepare the soup up to two days in advance, warming it just before serving.

Enjoy the luxurious and comforting taste of homemade roasted cauliflower soup and share it with loved ones. Your kitchen will be filled with enticing aromas that beckon everyone to the table. This recipe is not just about nourishment; it’s about creating warmth and memories through good food.

Recipe FAQs

Can I make this soup vegan?

Absolutely! To make this roasted cauliflower soup vegan, simply omit the cheese or use a dairy-free cheese substitute. Nutritional yeast can also provide a cheesy flavor without dairy.

How can I adjust the soup’s thickness?

If you prefer a thicker soup, reduce the amount of vegetable broth used. For a thinner consistency, add more broth gradually until you achieve your desired thickness. Blending more or less of the roasted cauliflower will also impact the soup’s texture.

Can I prepare this soup in advance?

Yes, this soup can be made ahead of time! Simply refrigerate it for up to 5 days after cooking or freeze it for up to 3 months. Reheat gently on the stovetop, adding broth to adjust consistency.

What other toppings can I use?

Feel free to get creative with toppings! Croutons, a swirl of coconut milk, or even a sprinkle of red pepper flakes can add a lovely finishing touch. Additionally, toasted nuts or seeds lend a delightful crunch.
