Cauliflower and Tomato Soup

If you’re craving a comforting soup recipe as much as I am this time of year, this dish is perfect for you. This tomato-basil and cauliflower soup is the perfect bowl of soup to warm up to on a chilly night. It’s so thick and creamy and full of flavor, you’ll love it!

One of my favorite restaurants has the best tomato basil soup and the best roasted cauliflower soup. When I go there, I like to put half of each in a bowl and mix them together. That’s where the inspiration for this cauliflower tomato soup comes from.

I tried to keep it light and healthy for us, so instead of using heavy cream like most tomato soups do – I used Greek yogurt to help make it rich and creamy. The end result was so delicious! It’s the perfect compliment to all of the healthy veggies in this dish.

Cooking Tips

  • Creaminess. I used Greek yogurt to add creaminess, yet keep it on the lighter side. You could sub the yogurt with heavy cream for an even thicker consistency if preferred.
  • Roasted cauliflower. For even more flavor, you could roast your cauliflower first. Simply season it with a drizzle of olive oil, kosher salt and pepper and roast in oven at 400ºF on a baking sheet for 25 to 30 minutes (flipping halfway through). Then add to soup according to directions and let simmer for about 5-10 minutes.
  • Blending. If you don’t have an immersion blender, feel free to use a regular blender. Just make sure to pour the soup into the blender in two batches so it doesn’t overflow!
  • Simmer. After you’ve blended the soup, mix in the cheese and let the mixture simmer for about 15 to 20 minutes. The consistency will continue to thicken as it simmers and the cheese will get perfectly melted and delicious.

Favorite Toppings

I like to garnish my soup with more chopped basil and a drizzle of sour cream. It adds great flavor and looks so pretty! It also tastes delicious served with a grilled cheese for dipping.
