Make this velvety roasted cauliflower soup for a comforting dinner. Roasting the cauliflower and garlic creates deep, nutty flavor. This easy recipe blends vegetables into a smooth, satisfying bowl, perfect for chilly evenings.

Ingredients

Scale
  • 1 large head cauliflower, cut into florets
  • 1 large yellow onion, roughly chopped
  • 4 cloves garlic, unpeeled
  • 3 tablespoons olive oil
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 4 cups vegetable broth
  • 1/2 cup heavy cream (or unsweetened plant-based milk for vegan option)
  • 1/4 teaspoon nutmeg
  • Optional: 1 tablespoon miso paste for depth

Instructions

  1. Preheat your oven to 400 degrees Fahrenheit (200 degrees Celsius).
  2. Toss the cauliflower florets, chopped onion, and unpeeled garlic cloves with olive oil, salt, and pepper on a large baking sheet. Spread them in a single layer.
  3. Roast for 25 to 30 minutes, stirring halfway through, until the cauliflower edges are deeply browned and tender. This step builds rich flavor.
  4. Remove the garlic cloves from their skins once cool enough to handle.
  5. Transfer the roasted vegetables (cauliflower, onion, and peeled garlic) to a large pot or Dutch oven.
  6. Pour in the vegetable broth. Bring the mixture to a simmer over medium heat. Cook for 10 minutes to allow flavors to meld.
  7. Remove the pot from the heat. Use an immersion blender to blend the soup until completely smooth and velvety. Alternatively, carefully transfer the soup in batches to a standard blender and blend until smooth, then return it to the pot.
  8. Stir in the heavy cream (or plant-based milk) and nutmeg. If using, dissolve the miso paste in a small amount of hot soup liquid before stirring it into the main pot.
  9. Heat the soup gently until warmed through. Do not boil after adding the cream.
  10. Taste and adjust salt and pepper as needed before serving your easy dinner soup.

Notes

  • For a richer flavor, roast the vegetables until they have significant caramelization.
  • If you prefer a cheesy cauliflower soup, stir in 1/2 cup of grated sharp cheddar cheese at the end until melted.
  • This soup freezes well for future quick weeknight soup meals.
