WATCH THE VIDEO TO SEE HOW IT’S MADE: You’d think soup would be easy, but so many soup recipes have you gathering a dozen or more ingredients, simmering on the stovetop for an hour or two—who has time for that on a weeknight?! This Roasted Cauliflower Soup isn’t one of those fussy soups, though. It requires only a few ingredients, it’s mostly hands-off, and you’ll have homemade soup ready to eat in under an hour. And not just any soup! The most delicious cauliflower soup you’ve ever had because instead of simply boiling the cauliflower in broth, it’s roasted first. Hello flavour! When cauliflower is roasted, it takes on a subtly nutty taste, with caramelised edges and a tender interior. To amp up the flavour even more, I roast the cauliflower with garlic and add that to the soup, too. This alone is enough to make for an incredible meal, but I highly recommend going the extra mile and adding some crispy chickpeas, tempeh bacon, or homemade croutons as a topping at the end.
Notes on Ingredients
Please note that this is important information on the ingredients and instructions and the FULL recipe with amounts and details can be found DOWN BELOW (scroll to it) in the recipe card.
Cauliflower Olive oil Salt Pepper Garlic – Smash the cloves while they’re still in the skins. Or, if you have roasted garlic on hand in the fridge, use that. Vidalia onion – Another variety of sweet onion will work, too. Thyme Vegetable broth – Here’s how to make your own vegetable broth.
How to Make Roasted Cauliflower Soup
Because the cauliflower needs to be roasted first, you can make this recipe in two steps: roast the cauliflower one day, and make the soup the next. Or you can double the roasted cauliflower and have half for dinner the first night and save the rest for soup! Prepare. Preheat your oven to 450ºF and line a baking sheet with a silicone mat or parchment paper. Roast the cauliflower. Place the cauliflower florets on the prepared baking sheet and toss them with olive oil, salt, and pepper. Add the smashed garlic cloves and roast for 15 minutes. Once cooled enough to handle, remove the garlic skins. Sauté the onion. Warm a half tablespoon of olive oil in a large pot set over medium-high heat. Add the onions and cook for about 8 minutes, or until lightly browned. Cook the soup. Add the roasted cauliflower, garlic, 2 sprigs of thyme, and vegetable broth to the pot with the onion. Bring the mixture to a boil, then reduce heat to a simmer for 15 minutes. Blend. Use an immersion blender to puree the soup in the pot, or let the soup cool and transfer it to a blender to puree it. Season to taste with salt and pepper. Serve. Divide the soup into bowls and top with additional cauliflower, crushed red pepper, thyme, and a drizzle of coconut milk, if desired.
Tips for Success
This soup is a cinch to make, but these hints and tips will make it even better!
Blending safely. The soup needs to cool before you transfer it to a blender. If needed, you can pour it back into the pot after blending and reheat it a bit before serving. Adding texture. If you like a chunkier cauliflower soup, you can reserve some of the roasted cauliflower and stir that into the soup after pureeing. Creamier soup. You can also add coconut milk or cashew cream for a richer, creamier soup.
