Roasted cauliflower soup is a perfect comfort food on any cold day. The roasted cauliflower adds depth and smokiness to the soup, while the creaminess soothes the taste buds. A hint of sweetness from the pears adds an extra layer to this hearty soup.
Preheat oven to 425 degrees. Line a large baking sheet with parchment paper. Set aside.
Chop two heads of cauliflower into large florets. Drizzle with 2 Tbsp of olive oil and season with salt and pepper. Toss to coat and then transfer to prepared baking sheet. Roast in the preheated oven for 20 minutes.
2 large cauliflower heads, 3 tablespoon extra-virgin olive oil, 2 teaspoons sea salt, ½ teaspoon ground pepper
Meanwhile, heat 1 Tbsp of olive oil in a large stock pot (I used a 6-qt) over medium heat. Add onions and cook for 1-2 minutes. Add pears or apples and garlic. Continue cooking, stirring occasionally, for 10 minutes.
2 medium white onions, 2 pears or green apples, 2 cloves garlic
Transfer the roasted cauliflower to the stock pot and add the vegetable broth. Add enough water to almost cover the cauliflower, if needed.
8 cups vegetable broth, Water
Bring to a boil over medium-high heat. Then, reduce the heat to low and cook, uncovered, for 40-45 minutes, or until cauliflower is easily pierced with a fork.
Using an immersion blender (be careful because the soup will be hot), blend to desired consistency.
Notes
For a thicker soup, reduce the amount of broth or water that is used. Alternatively, you can thin the soup out with additional broth or with a small amount of milk.
If you do not have an immersion blender, carefully transfer the soup, in batches, into a blender and pulse to blend to the right consistency.
