Ingredients
For the Soup Base
- 2 heads of cauliflower (about 4 pounds)
- Kosher salt
- Black pepper
- Extra virgin olive oil
Aromatics and Spices
- 1 small yellow onion, chopped
- 5 garlic cloves, chopped
- 2 teaspoons ground cumin
- 2 1/2 teaspoons sweet paprika
- 1 teaspoon ground sumac
- 1/4 teaspoon ground turmeric
Liquid Ingredients
- 32 ounces (4 cups) low-sodium vegetable broth
- 2 cups whole milk or unseasoned, unsweetened plant-based milk of choice
- Juice of 1/2 lemon
Fresh Herbs
- 1 cup chopped fresh dill
How to Make Roasted Cauliflower Soup
Step 1: Preheat the Oven
Preheat your oven to 425°F. Cut the cauliflower in half from top to bottom through the stem. Use your knife to slice off each floret. Ensure all florets are about the same size by cutting larger ones into smaller pieces.
Step 2: Season the Cauliflower
Transfer the cauliflower florets onto a large sheet pan. Sprinkle them generously with kosher salt and black pepper. Drizzle with extra virgin olive oil. Toss everything together until well-coated and spread evenly on the pan.
Step 3: Roast the Cauliflower
Roast in the oven for about 45 minutes, turning halfway through (around 25 minutes). You want the cauliflower to be tender and browned in some areas. Remove from the oven when done.
Step 4: Sauté the Onions
In a large heavy pot or Dutch oven, heat 2 tablespoons of olive oil over medium heat until shimmering but not smoking. Add the chopped onion and cook until translucent, around 7 minutes. Then add garlic, cumin, paprika, sumac, and turmeric; stir until fragrant (about 1 minute).
Step 5: Simmer
Add three-fourths of the roasted cauliflower (reserve some for garnish). Stir well so that it coats with spices. Pour in vegetable broth and one cup of water. Raise heat until it boils; then reduce to medium heat and cover partially. Simmer for about 5 to 7 minutes until slightly thickened.
Step 6: Blend
Remove from heat temporarily. Using an immersion blender, blend until you reach your desired smoothness—some prefer it chunky while others like it completely smooth. If using a standard blender or food processor, ensure plenty of room at the top to prevent spills.
Step 7: Finish and Serve
Return your blended mixture to medium heat. Stir in whole milk (or plant-based milk), lemon juice, and reserved roasted cauliflower. Heat briefly until warmed through. Adjust salt if necessary before stirring in fresh dill. Serve hot for maximum enjoyment!
How to Serve Roasted Cauliflower Soup
Roasted cauliflower soup is a versatile dish that can be enjoyed in various ways. Whether you prefer it as a main course or a starter, this creamy soup pairs well with many accompaniments.
With Crusty Bread
- A thick slice of sourdough or whole grain bread is perfect for dipping into the soup. The crusty exterior and soft interior complement the creamy texture.
Topped with Croutons
- Add crunchy homemade or store-bought croutons for extra texture. They provide a delightful contrast to the smooth soup.
Drizzled with Olive Oil

How to Perfect Roasted Cauliflower Soup
To make your roasted cauliflower soup even better, consider these tips for achieving optimal flavor and texture.
-
Use fresh ingredients: Fresh cauliflower, onions, and herbs enhance the taste significantly. Avoid wilted or old vegetables for the best results.
-
Roast cauliflower well: Ensure the cauliflower is nicely browned before adding it to the pot. This caramelization adds depth of flavor to your soup.
-
Adjust seasoning: Taste your soup as you cook and adjust salt and spices accordingly. Balancing flavors is key to a delicious outcome.
-
Experiment with toppings: Don’t hesitate to try different toppings like toasted pine nuts or feta cheese for added flavor and texture.

Common Mistakes to Avoid
When making Roasted Cauliflower Soup, it’s easy to overlook a few key steps. Here are some common mistakes to watch out for:
-
Overcrowding the Pan: If you place too much cauliflower on one pan, it can steam instead of roast. Spread the florets evenly or use two pans to ensure even browning.
-
Not Seasoning Enough: A lack of seasoning can lead to bland soup. Make sure to generously season your cauliflower with salt and pepper before roasting for maximum flavor.
-
Skipping the Blend: Failing to blend the soup properly can result in an undesirable texture. Use an immersion blender or transfer to a stand blender until you achieve your preferred smoothness.
-
Ignoring Fresh Herbs: Skipping fresh herbs like dill at the end can diminish the flavor profile. Always add fresh herbs right before serving for a burst of freshness.
-
Using High-Sodium Broth: Using regular broth can make your soup too salty. Opt for low-sodium vegetable broth so you can control the saltiness.
