Broccoli and Cauliflower Soup

This is everything a soup should be: chock full of flavor, coziness, and comfort. Plus, it's a very easy weeknight meal to get on the table. Just serve alongside some crusty bread, or maybe some grilled cheese(!) and you're good to go!

Equipment

  • Immersion Blender or Stand blender

Ingredients
  

  • 2 tablespoon olive oil
  • 1 carrot grated
  • 2 stalks celery diced
  • 1 onion chopped
  • 3 cloves garlic smashed
  • 1 teaspoon red pepper flakes optional
  • 2 heads broccoli chopped
  • 1 head cauliflower chopped
  • 3 C chicken broth (or vegetable broth)
  • 2 C milk
  • 2 C cheddar cheese grated
  • 2 teaspoon salt
  • ¼ teaspoon black pepper

Instructions
 

  • Heat olive oil in a large saucepan or Dutch oven over medium high heat. Add the carrot, celery and onion. Sauté for about five minutes, until the vegetables start to soften.
  • Add the garlic and hot pepper flakes if using, and cook for another minute.
  • Add the broccoli, cauliflower, and stock. Turn the heat up and bring to a boil. Once boiling, turn the heat back down to a simmer, cover with a lid, and let cook for 20-25 minutes. The broccoli and cauliflower should be fork tender.
  • Using an immersion blender (or transferring the soup to a stand blender), blend the soup until smooth. You can also leave it a bit chunky if you want!
  • Add the milk, cheese, pepper and salt. Stir until the cheese is melted.
  • Serve with extra cheese, sour cream, and bacon on top, if desired.

Notes

You don't have to add the hot pepper flakes, but they really give the soup a little something extra. Feel free to scale up or back the amount you use. 
For deeper flavor, try using old, sharp cheddar cheese. 
DO NOT skimp on the salt. This soup really leans on it to bring out the best in the flavor of the broccoli.
