Gluten-free Broccoli Cheese Soup

The secret ingredient in this broccoli cheese soup recipe is cauliflower. When cooked, cauliflower gets really super creamy, and it adds so much lovely texture to this soup without overpowering the flavor. You won’t even taste it!

Also, be sure to use good quality sharp cheddar cheese. Or even extra sharp. That tangy cheddar flavor is what you’re looking for, and don’t forget to save a bit to garnish the tops of the bowls.

How to make the best gluten-free Broccoli Cheddar Soup

  1. Cut the broccoli and cauliflower into small florets and set them aside. Just use the crowns for this recipe; avoid using the stem and core.
  2. Heat the oil on medium-high heat and saute the broccoli and cauliflower for 3-5 minutes, then add the garlic and saute for an additional minute.
  3. Add the chicken broth and heavy cream to the pot and bring it to a boil, then immediately turn the heat down to a simmer and simmer for 10-12 minutes. Don’t overcook the broccoli and cauliflower.
  4. Puree the mixture with an immersion blender or regular blender. 
  5. Turn the heat to low and add the cheddar cheese, stirring as you add it in, until melted and combined.
  6. Serve immediately with a dash of Everything But The Bagel seasoning and sliced green onions.

Tips & substitutions

  • Don’t overcook the vegetables! You don’t want the broccoli and cauliflower to be mushy.
  • You can use vegetable broth or bone broth instead of chicken broth.
  • Use low or no-sodium-added broth to control the salt.
  • You can use half-and-half cream to lighten it up if you like.
  • Cheese is salty. Taste the soup before adjusting the seasoning.

Serving suggestions

There’s nothing tastier than a soup and sandwich, so I love pairing this broccoli cheddar soup with a grilled cheese sandwich or even a decadent lobster roll. This fabulous soup also makes a terrific first course, and paired with main dishes like Chicken Veronique or vegetable-sausage foil packs, it’s a hearty and delicious meal.
