Cauliflower Soup | The Mediterranean Dish (2024)

This cauliflower soup is boldly flavored with warming Mediterranean spices like cumin, turmeric, and paprika. Made with whole milk, it’s nice and creamy but not heavy. Make this light, fresh, and flavorful take on roasted cauliflower soup for a cozy night in.

Cauliflower takes on flavor and texture like a champ, which makes it the ideal vegetable for pairing with big flavors. Why waste an opportunity to throw a flavor party?

For my vegetarian cauliflower soup recipe, I first roast the florets in the oven, which carmelizes the edges to bring out some of its natural sweetness. Next, I add cumin for warmth, paprika for a mild kick, sumac for citrusy balance, and turmeric for an earthy, peppery undertone. Typical cauliflower soup is often loaded with heavy cream, which I don’t think it needs. Whole milk adds enough creaminess without dulling the flavor.

While, roasted cauliflower soup is one of my favorite recipes to make when the weather turns, this sturdy vegetable is also incredible when roasted whole for a vegetarian centerpiece or cut into cauliflower steaks and topped with Chermoula.

Don’t forget the finishing touches! This might sound surprising, but a splash of lemon juice and a handful of fresh dill bring balance and brightness, which makes this soup that much more exciting.

Ingredients for this Roasted Cauliflower Soup Recipe

Cauliflower can take a lot of seasonings and spices to really shine. Warming spices and fresh aromatics give it a nice warming kick and super savory, comforting flavor. Here’s what you’ll need to make this cauliflower soup recipe:

• Cauliflower: Look for firm, tight cauliflower heads with no browning.
• Extra virgin olive oil: I like a medium-intensity oil here, like our Private Reserve Greek extra virgin olive oil. Drizzle some over top of each bowl for extra richness.
• Aromatics: One yellow onion and five garlic cloves give this soup a sweet and savory depth of flavor. You can substitute the onion with white onion or 3 shallots if you’d like.
• Spices: Basic pantry spices of Spanish paprika, cumin, and turmeric bring a comforting savory flavor. Sumac gives some tartness for balance–you can learn all about this Mediterranean wonder spice in our guide, order online, or substitute with a grating of lemon zest just before serving.
• Broth: A low-sodium vegetable broth brings a nice umami flavor, or you can substitute with store bought or homemade chicken stock.
• Whole milk: Milk is a lighter option than heavy cream, and it makes the soup perfectly creamy without overpowering the spices. You can also leave it out to make this soup vegan, or replace it with an unflavored, unsweetened plant-based milk.
• Lemon juice: Lifts the hearty, creamy soup.
• Fresh dill: Gives the soup a fresh herbal element. You can substitute with any tender savory herb, like chive or parsley.

How to Make Cauliflower Soup

This roasted cauliflower soup is a beloved family meal for a reason: It’s easy to make, feeds a crowd and is on the healthy side. Here are the steps:

• Get ready. Preheat your oven to 425°F. Cut 2 cauliflower heads in half from top to bottom through the stem. Use the tip of your knife to slice off each individual floret, discarding the stem. Slice any larger florets into smaller pieces so all of them are about the same size.
• Season the cauliflower. Transfer the cauliflower to a large sheet pan. Sprinkle with salt and pepper and drizzle generously with olive oil. Toss to coat, then spread evenly without overlapping–use two sheet pans if you need to.
• Roast the cauliflower. Roast, turning at about 25 minutes, until the cauliflower is tender and deeply browned in some parts, about 45 minutes in total. Remove from the oven.
• Prepare the aromatics. While the cauliflower roasts, chop 1 onion and 5 garlic cloves.
• Sauté the onions. In a large heavy pot or Dutch oven, heat 2 tablespoons of olive oil over medium until shimmering but not smoking. Add the onion and cook until translucent, about 7 minutes. Add the garlic, 2 teaspoons cumin, 2 ½ teaspoons sweet paprika, 1 teaspoon sumac, and ¼ teaspoon turmeric. Stir just until fragrant, about 1 minute.
• Simmer. Add ¾ of the cauliflower (reserve the remaining for later). Stir to coat well with the spices, then add 4 cups of broth and 1 cup of water. Turn the heat to high to bring to a boil, then lower heat to medium and cover part-way. Simmer until thickened slightly, 5 to 7 minutes. While it boils, prepare 1 cup of chopped dill, discarding any tougher stems.
• Blend. Uncover and remove from heat momentarily. Use an immersion blender to blend until you achieve your desired smoothness–I keep mine a bit on the chunky side. You can also transfer to a blender or food processor, just be sure to leave plenty of room at the top and blend with the steam cap off.
• Finish and serve. Return to a medium heat and stir in 2 cups milk, the juice from ½ lemon, and reserved cauliflower. Cook briefly so that the soup is all warmed through. Test and adjust salt as needed. Finally, stir in the dill and serve hot.

How to Store and Reheat Leftover Soup

If you have leftovers, let the roasted cauliflower soup cool completely, then store covered in your fridge for 3 to 4 days. To reheat, warm in a saucepan set over medium heat, stirring often. Take care not to let it come to a boil, and add a splash more water or broth to thin as necessary.

Can You Freeze Cauliflower Soup?

Yes, with a caveat: Soups that contain milk or cream tend to develop an unappetizing grainy texture and separate when defrosted. If you plan to prepare this soup ahead of time and freeze:

• Don’t add the milk. Allow to cool completely, then transfer to a freezer-safe container with some room at the top to allow for expansion.
• Label the soup. Write “Add Milk” along with the date on a piece of tape and stick it to the lid. Freeze for up to 2 months.
• Defrost, finish, and enjoy. Defrost in your refrigerator overnight, then heat over medium, stirring often until the soup is hot. Add the milk and stir until warmed through, then enjoy hot.

What to Serve with Cauliflower Soup

This cauliflower soup is hearty enough to stand on its own, you really need nothing more. If you’d like some sides, go with a classic soup and salad combination with bread for dipping.

For my family, nothing is better than some crisp-on-the-outside, chewy-on-the-inside focaccia bread or a rustic crusty bread. I sometimes add a salad like my orange beet salad or lemony arugula salad.
