A hearty winter or spring vegetarian soup from the editors behind the One-Block Diet blog.
2 lb. Yukon Gold potatoes, unpeeled, cut into 3/4" chunks (about 6 cups)
1 head cauliflower, about 2-1/2 lb., cut into florets
1 head broccoli romanesco, about 1-1/4 lb., cut into florets
4 cups (about 1 bunch) chopped broccoli rabe plus any flowers
3 tbsp extra virgin olive oil, plus more for serving
1 tbsp fine sea salt
3 tbsp chopped garlic
1 cup chopped white onion
1/2 cup heavy cream (optional)
Chopped fresh rosemary, plus any flowers, for garnish
Step 1: Preheat the oven to 350°F.
Step 2: Put half the potatoes on a rimmed baking sheet.
Step 3: Pick out 3 cups bite-size cauliflower florets and combine them with the broccoli romanesco and broccoli rabe on another rimmed baking sheet (set aside any broccoli rabe flowers).
Step 4: Chop the remaining cauliflower and set aside. Drizzle 1 tbsp of the oil and sprinkle 1 tsp of the salt over each baking sheet.
Step 5: Roast the vegetables, stirring often, until golden brown and tender when pierced with a fork, about 20 minutes for the mixed vegetables and 25 minutes for the potatoes.
Step 6: Meanwhile, heat the remaining 1 tbsp oil in a large pot over medium heat. Add the garlic and onion and cook, stirring often, until translucent, about 5 minutes. Add the remaining potatoes, the chopped cauliflower, and 6 cups water and bring to a simmer. Cover and cook until the vegetables are tender, about 15 minutes. Remove from the heat and let cool slightly.
Step 7: Working in batches, ladle about 2 cups of the liquid and vegetables into a blender and process until smooth. Pour through a fine-mesh strainer set over a large bowl, using the back of the ladle to push the soup through.
Step 8: Pour the purée back into the pot and bring to a simmer over low heat. Stir in the cream and the remaining 1 tsp salt, then add the roasted vegetables and heat through.
Step 9: Serve the chowder in deep soup bowls, drizzled with oil and sprinkled with chopped rosemary and broccoli rabe and rosemary flowers.
