This stuff is so good however that all you need is to put it in a bowl and serve – the flavor will speak for itself.

  • Broccoli
  • Cheddar
  • Nutmeg

How to make broccoli cheddar soup

Cut a broccoli into florets, and dice an onion. Add to a slow cooker along with water, nutmeg, a stock cube and some salt and pepper. Cook on low setting for 4-6 hours until the broccoli is soft. Use an immersion blender to blend the soup directly in the slow cooker. Alternatively, you can pour the vegetables and liquid into a blender, blend until smooth, and add the soup back to the slow cooker.

Next, we make a milky sauce to thicken the soup and give it that perfect, creamy consistency. Melt some butter in a pot, and add flour. Stir until combined. Slowly add milk, little by little, by stirring to prevent clumps. Add the sauce to the slow cooker. Stir to combine, then slowly add the cheese. Only add one small handful at a time, and stir until it’s melted and evenly distributed to the soup. When all the cheese is added, put the lid back on and cook for another 15 minutes – 2 hours. Add salt and pepper to taste, and serve.

    You wouldn’t believe it, but my daughter would love this soup. I know broccoli is not a kid-friendly veggie, but she loves broccoli cream soups. Thanks for sharing.

      Soups are probably my favorite way to make kids eat veggies. Try find a 5 year old that doesn’t want to eat “green dragon soup”!
