Ingredients
For this delicious Roasted Cauliflower Soup, you’ll need the following ingredients:
- 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 plant-based milk of choice
- Juice of 1/2 lemon
- 1 cup chopped fresh dill
How to Make Roasted Cauliflower Soup
Step 1: Get Ready
Preheat your oven to 425°F. Cut the cauliflower in half from top to bottom through the stem. Use the tip of your knife to slice off each individual floret. Slice any larger florets into smaller pieces so all are about the same size.
Step 2: Season the Cauliflower
Transfer the cauliflower to a large sheet pan. Sprinkle with kosher salt and black pepper, then drizzle generously with extra virgin olive oil. Toss to coat well, then spread evenly without overlapping—use two sheet pans if necessary.
Step 3: Roast the Cauliflower
Roast in the oven for about 45 minutes total, turning after about 25 minutes. You want it tender and deeply browned in some spots before removing it from the oven.
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, approximately 7 minutes. Then add chopped garlic, cumin, paprika, sumac, and turmeric; stir until fragrant for about 1 minute.
Step 5: Simmer
Add three-fourths of your roasted cauliflower (reserve some for later). Stir well to coat with spices. Add vegetable broth and one cup of water. Increase heat to high until boiling, then reduce to medium heat and cover partway. Simmer until slightly thickened, around 5 to 7 minutes.
Step 6: Blend
Uncover your pot and temporarily remove it from heat. Use an immersion blender to puree until you reach your desired smoothness; keeping some chunks is perfectly fine! Alternatively, transfer in batches to a standard blender but remember to leave space at the top for steam.
Step 7: Finish and Serve
Return your blended soup to medium heat; stir in whole milk (or plant-based alternative), lemon juice, and reserved roasted cauliflower pieces. Heat briefly until warmed throughout. Taste and adjust salt as needed before stirring in fresh dill. Serve hot for a comforting meal!
