Ingredients
Here are the ingredients you’ll need for this delicious Roasted Cauliflower Soup:
- 2 heads of cauliflower (about 4 pounds)
- Kosher salt
- Black pepper
- Extra virgin olive oil
- 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
- 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
- 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 individual floret. Slice any larger florets into smaller pieces so they all cook evenly.
Step 2: Season the Cauliflower
Transfer the cauliflower florets to a large sheet pan. Sprinkle them with kosher salt and black pepper. Drizzle generously with extra virgin olive oil. Toss everything together until well coated, then spread them out evenly on the pan without overlapping.
Step 3: Roast the Cauliflower
Place the sheet pan in the oven and roast for about 45 minutes. Turn the florets halfway through cooking (around 25 minutes) until they are tender and deeply browned in some areas.
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 chopped onion and cook until translucent, about 7 minutes. Then add garlic, cumin, paprika, sumac, and turmeric; stir until fragrant, about 1 minute.
Step 5: Simmer
Add about three-fourths of the roasted cauliflower to the pot (reserve some for later). Stir well to coat with spices. Pour in low-sodium vegetable broth and one cup of water. Increase heat to high until boiling, then reduce heat to medium and cover partially. Simmer for about 5 to 7 minutes until slightly thickened.
Step 6: Blend
Remove from heat momentarily once simmering is complete. Use an immersion blender to blend until you reach your desired smoothness—keeping some texture is recommended. If using a standard blender, ensure there’s enough room at the top for steam before blending.
Step 7: Finish and Serve
Return the pot to medium heat and stir in whole milk (or plant-based alternative), lemon juice, and reserved roasted cauliflower pieces. Cook briefly until warmed through. Adjust salt as needed before stirring in chopped fresh dill. Serve hot!

Common Mistakes to Avoid
Roasted Cauliflower Soup is a delightful dish, but there are common pitfalls to watch for. Here are some mistakes to avoid:
-
Skipping the seasoning: Failing to season the cauliflower before roasting can lead to bland soup. Always sprinkle salt and pepper generously before cooking.
-
Overcooking the cauliflower: Cooking the cauliflower too long can make it mushy. Aim for tender but not falling apart, usually around 45 minutes in the oven.
-
Not blending enough: A chunky soup may not have the creamy texture you desire. Blend until you reach your preferred smoothness, adjusting as needed.
-
Using cold milk: Adding cold milk can lower the soup’s temperature drastically. Warm the milk briefly before stirring it in for a better result.
-
Neglecting garnishes: Skipping fresh herbs or lemon juice can reduce flavor complexity. Finish with chopped dill or a squeeze of lemon for added brightness.
