How to Make Roasted Cauliflower Soup
-
Preheat Your Oven: Begin by preheating your oven to 400°F (200°C). This step ensures that your cauliflower roasts evenly, creating a beautiful, caramelized flavor.
-
Prepare the Cauliflower: Chop your fresh cauliflower into bite-sized florets. Toss them in a bowl with olive oil, salt, and pepper, ensuring each piece is well-coated for maximum flavor.
-
Roast Cauliflower: Spread the cauliflower florets on a baking sheet in a single layer. Roast in the oven for 25-30 minutes, or until they are golden brown and tender to the fork.
-
Sauté Aromatics: While the cauliflower roasts, heat a glug of olive oil in a large pot over medium heat. Add the diced onion and minced garlic, sautéing until they are soft and fragrant, about 5-7 minutes.
-
Blend the Soup: Once the cauliflower is roasted, add it to the pot along with the vegetable broth. Bring to a gentle simmer, then use an immersion blender to puree until the soup is smooth and creamy.
-
Season the Soup: Stir in the fresh dill, then taste and adjust seasoning with salt and pepper according to your preference. The dill should brighten up the flavor beautifully!
-
Serve with Love: Ladle the delicious soup into bowls and, for an extra touch, garnish with some additional dill or a dollop of Greek yogurt.
Optional: For an added layer of flavor, sprinkle with a bit of nutmeg before serving.

Storage Tips for Roasted Cauliflower Soup
Fridge: Store your Roasted Cauliflower Soup in an airtight container for up to 4 days. Make sure it’s completely cooled before sealing to avoid condensation.
Freezer: If you want to keep your soup longer, freeze it for up to 3 months in freezer-safe containers. Leave a little space at the top for expansion as it freezes.
Reheating: Gently reheat on the stovetop over low heat, stirring occasionally. If the soup thickens, add extra vegetable broth or milk to achieve your desired consistency.
Serving: For extra joy, serve with a sprinkle of fresh herbs or a dollop of Greek yogurt just before enjoying your creamy Roasted Cauliflower Soup!
Make Ahead Options
These creamy Roasted Cauliflower Soup is perfect for meal prep enthusiasts! You can chop and toss the cauliflower with olive oil, salt, and pepper up to 24 hours in advance. Store the prepared florets in an airtight container in the refrigerator to keep them fresh. Additionally, you can sauté the onion and garlic up to 3 days before you plan to make the soup, allowing them to boost the flavor before blending. When you’re ready to enjoy your soup, simply roast the cauliflower, blend it with the prepared onion-garlic mixture and vegetable broth, season with dill, and serve warm. This way, you’ll enjoy just as delicious results with minimal effort on busy weeknights!
Expert Tips for Creamy Roasted Cauliflower Soup
- Use Fresh Ingredients: Fresh cauliflower and herbs make a significant difference in flavor. Avoid pre-packaged, older vegetables for the best results.
- Mind the Roasting: Ensure your cauliflower florets are spaced out on the baking sheet; overcrowding can lead to steaming rather than roasting, which impacts texture.
- Blending Technique: An immersion blender offers the smoothest finish, but if you use a standalone blender, allow the soup to cool slightly to prevent splattering!
- Versatile Seasoning: Don’t hesitate to add a pinch of cayenne or nutmeg to elevate the flavor profile of your roasted cauliflower soup; experiment and find your perfect balance!
- Make it Ahead: This soup stores beautifully in the fridge for up to 4 days. Reheat gently on the stove, adding a splash of broth or milk for the right consistency.

Roasted Cauliflower Soup Recipe FAQs
What should I look for when selecting cauliflower?
Absolutely! When picking cauliflower, look for heads that are firm and compact, with a clean, creamy white color. Any dark spots or brown areas may indicate aging, so best to avoid those! Fresh cauliflower gives the best flavor and texture for your soup.
How should I store Roasted Cauliflower Soup?
I recommend storing your soup in an airtight container in the refrigerator for up to 4 days. Make sure it’s completely cooled before sealing to prevent condensation. For longer storage, you can keep it in the freezer for up to 3 months; just leave a little space at the top of the container for expansion.
Can I freeze Roasted Cauliflower Soup?
Absolutely! To freeze, let your soup cool completely, then transfer it to freezer-safe containers, leaving about an inch of space at the top for expansion. When you’re ready to enjoy it, simply thaw in the fridge overnight and reheat gently on the stovetop, adding a splash of broth if needed to adjust the consistency.
Why does my soup not have the creamy texture I expected?
Very! If your soup is too thin, it might be due to adding too much broth during blending. To thicken it up, you can simmer it gently on low heat for a while to reduce the liquid. Alternatively, blend in some more roasted cauliflower to create that dreamy, velvety texture!
Is this Roasted Cauliflower Soup suitable for those with allergies?
Certainly! This soup is vegetarian and can be made vegan by substituting the Greek yogurt with a dairy-free option. If you have nut allergies, it’s safe as it doesn’t include any nuts. Just be cautious about any broth you use, as some may contain gluten or other allergens. Always check labels to ensure safety!
