Ingredients

  • 1/2 head cauliflower , cut into large florets*
  • 5 carrots , diced**
  • 1 parsnip , diced***
  • 2 red bell peppers , cut into large chunks
  • 1 yellow summer squash , cut into large chunks****
  • 1 onion , quartered*****
  • 4 garlic cloves , with the skin on
  • 2 Tbsp. olive oil
  • 1 1/2 Tbsp. lemon juice
  • 1 sprig fresh rosemary , still on the stem
  • 1 bay leaf
  • 5-6 cups vegetable broth

Instructions

  • Preheat the oven. Arrange a rack in the middle of the oven. Heat the oven to 400ºF/204ºC
  • Roast the vegetables. Add all the vegetables to a baking sheet, drizzle with oil, sprinkle with salt, and toss to coat. Spread all the vegetables into a single layer so they roast evenly and brown at the edges and roast until the carrots are tender when pierced with a fork and the vegetables begin to brown slightly, for about 35 minutes, tossing the vegetables halfway through roasting. 
  • Simmer. First, remove the garlic cloves from their skins. Then, transfer the roasted vegetables to a large pot, add the rosemary and bay leaf, cover everything with vegetable broth, and bring it to a boil over high heat. Turn the heat off, cover the soup with a lid, and let it sit for 15 minutes. Blend. Add the roasted vegetables, vegetable broth, and lemon juice to a high-speed blender and blend on high until smooth. I love rosemary, so I typically blend some rosemary leaves as well. If your soup is too thick, add up to 1 cup/240 ml more broth and blend. I recommend starting with less broth and adding more as needed - you can always add more to thin the soup out, but you can't take it out if you add too much at first. Serve immediately, straight out of the blender.

  • Season. Taste and adjust the flavor as needed, adding more salt for saltiness and lemon juice for acidity.
  • Serve. Pour the soup into serving bowls - it will be hot straight out of the blender. Garnish with a freshly chopped parsley and a sprinkle of black pepper.
  • Store. Leftover soup keeps well covered in the refrigerator for 3-4 days. For longer-term storage, freeze in an airtight container for up to 3 months.
  • Reheat. Transfer frozen soup into the refrigerator 24 hours before reheating to thaw slightly. Reheat in a pot on the stovetop over medium-low heat, stirring frequently, until hot. Add ¼ cup/60 ml water/broth at a time if too thick.
