Ingredients

  • 3 cups mixed vegetables (carrots, bell peppers, zucchini, cauliflower, and onions)
  • 3 tablespoons olive oil
  • 4 cloves garlic, minced
  • 1 large onion, chopped
  • 1 teaspoon dried thyme
  • 1 teaspoon dried rosemary
  • 1 teaspoon smoked paprika
  • 5 cups vegetable broth
  • Salt and pepper to taste
  • 1 tablespoon balsamic vinegar (optional, for added depth)
  • Fresh parsley for garnish

Equipment

  • Baking sheet for roasting vegetables
  • Large soup pot or Dutch oven
  • Blender or immersion blender for pureeing the soup
  • Measuring spoons and cups
  • Sharp knife and cutting board
  • Ladle for serving

Instructions

  1. Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper or lightly grease it.
  2. Prepare the vegetables: Wash and chop your mixed vegetables into bite-sized pieces. Spread them evenly on the baking sheet.
  3. Drizzle with olive oil: Toss the vegetables with olive oil, salt, pepper, smoked paprika, thyme, and rosemary until they are well coated.
  4. Roast the vegetables: Place the baking sheet in the oven and roast for 25-30 minutes, stirring halfway through, until the vegetables are tender and slightly caramelized.
  5. Sauté the aromatics: While the vegetables roast, heat a tablespoon of olive oil in a large soup pot over medium heat. Add the chopped onion and garlic, cooking until translucent and fragrant, about 5 minutes.
  6. Add roasted vegetables to the pot: Once roasted, add the vegetables to the pot with the sautéed onions and garlic.
  7. Pour in vegetable broth: Add the broth to the pot, bring to a boil, then reduce to a simmer. Let it cook for 10 minutes to marry the flavors.
  8. Blend the soup: Use an immersion blender directly in the pot or carefully transfer the soup to a blender in batches. Blend until smooth and creamy. If you prefer a chunkier texture, blend only half the soup.
  9. Taste and adjust seasoning: Add salt, pepper, and balsamic vinegar if using. Stir well.
  10. Serve hot: Ladle into bowls and garnish with fresh parsley. Enjoy your comforting roasted vegetable soup!

Tips & Variations

For a richer flavor, try adding a splash of coconut milk or a dollop of cashew cream when blending.

You can easily swap vegetables based on what’s fresh or in your fridge. Sweet potatoes, butternut squash, or tomatoes work wonderfully roasted and blended.

To boost protein, add cooked lentils or beans after blending for a heartier meal.

Spice lovers can add a pinch of cayenne or a dash of your favorite chili powder. For a smoky twist, try adding a little chipotle pepper in adobo sauce.

If you want to make this soup in advance, it keeps well in the fridge for up to 4 days or freezes beautifully for up to 3 months.
