How to Make Roasted Cauliflower Soup
-
Preheat your oven to 425°F. Start by cutting the cauliflower in half from top to bottom through the stem. Then slice off each floret, trimming larger ones into smaller pieces for even roasting.
-
Prepare the cauliflower for roasting by placing it on a large sheet pan. Generously sprinkle with kosher salt and black pepper, then drizzle with extra virgin olive oil. Gently toss to coat, spreading the florets evenly without overlapping.
-
Roast the cauliflower in the oven, turning it halfway through at about 25 minutes. Look for a tender texture and beautiful browning, which should take about 45 minutes total. Once done, remove from the oven and let it cool slightly.
-
Sauté the onions in a large heavy pot or Dutch oven with 2 tablespoons of olive oil over medium heat. Cook until translucent, roughly 7 minutes. Add in the garlic, cumin, paprika, sumac, and turmeric, stirring until fragrant—about 1 minute.
-
Combine about 3/4 of the roasted cauliflower into the pot. Stir well to coat the florets with the spices, then add the vegetable broth and 1 cup of water. Bring the mixture to a boil, then lower the heat to medium, covering partially. Let it simmer for 5 to 7 minutes until slightly thickened.
-
Blend the soup until smooth using an immersion blender to achieve your desired consistency. It should be creamy and comforting!
-
Stir in the milk, lemon juice, and the reserved cauliflower. Warm through over medium heat, adjusting salt to taste. Finally, mix in the fresh dill before serving hot.
Optional: Drizzle with extra olive oil and a sprinkle of paprika for a beautiful presentation.

Expert Tips for Roasted Cauliflower Soup
-
Roasting Perfection: Make sure the cauliflower florets are spread out on the pan; overcrowding can lead to steaming instead of roasting, which affects flavor.
-
Flavor Depth: Don’t skip the spices! Each one enhances the soup; adjusting them according to your taste can elevate the roasted cauliflower soup to new heights.
-
Blending Trick: For a silky texture, blend the soup while it’s still warm. Cold soup can be challenging to achieve a smooth consistency, so blend thoroughly.
-
Milk Choices: If using plant-based milk, ensure it’s unseasoned and unsweetened to maintain the soup’s flavor balance. Taste as you go!
-
Garnish Delight: Fresh herbs make a difference! A sprinkle of dill or even a drizzle of olive oil on top adds a wonderful finishing touch to your roasted cauliflower soup.
How to Store and Freeze Roasted Cauliflower Soup
Fridge: Store your Roasted Cauliflower Soup in an airtight container for up to 3 days. Allow it to cool completely before sealing to prevent condensation.
Freezer: For longer storage, freeze the soup in portioned airtight containers or freezer bags for up to 3 months. Leave some space in the container for expansion.
Reheating: Thaw overnight in the fridge before reheating. Gently warm on the stove over low heat, adding a splash of milk if needed to regain creaminess.
Serving Tip: Stir in freshly chopped dill just before serving to revive the herbaceous flavor after storage!

Roasted Cauliflower Soup Recipe FAQs
How do I choose the best cauliflower for this soup?
Absolutely! When selecting cauliflower, look for heads that are dense and firm with tight, compact florets. The color should be bright white or cream, with dark green leaves. Avoid any heads that show signs of browning or dark spots all over, as they indicate over-ripeness.
How can I store leftovers of Roasted Cauliflower Soup?
Very easy! Allow your Roasted Cauliflower Soup to cool completely before transferring it to an airtight container. Store it in the refrigerator for up to 3 days. For best preservation, make sure the container is well-sealed to keep it fresh and flavorful.
Can I freeze Roasted Cauliflower Soup?
Absolutely! For freezing, pour your cooled soup into portioned airtight containers or freezer bags, leaving some space for expansion. It can be stored in the freezer for up to 3 months. To reheat, thaw it overnight in the fridge and warm gently on the stove over low heat, adding a splash of milk if needed to restore creaminess.
What if my soup ends up too thick?
No worries! If your Roasted Cauliflower Soup is thicker than desired, simply stir in a bit more broth or milk until it reaches your preferred consistency. You can heat it gently on the stove while adding the liquid for an even blend.
Can I modify this recipe for dietary restrictions?
Definitely! If you’re making this Roasted Cauliflower Soup for someone with dietary allergies, consider using unsweetened coconut milk or almond milk as your dairy substitute. For a vegan version, simply skip the milk or use a non-dairy alternative and leave out any animal-based broths.
How can I revive the flavors after storing the soup?
