  • 1 broccoli (cut into florets)
  • 1 chopped onion
  • 1 vegetable stock cube
  • ½ teaspoon nutmeg
  • 3 cups water (700 ml)
  • 2 tablespoons butter
  • 1 tablespoon cornstarch
  • ½ cup milk (100 ml)
  • 1 cup shredded cheddar (100 g)


  • Cut the broccoli into florets, and finely dice the onion. Add both vegetables to your slow cooker, along with water, the stock cube and nutmeg.
  • Cover with a lid, and leave the slow cooker to cook for 2-3 hours on high, or 4-5 hours on low.
  • Remove the lid from the crock pot, and blend the soup smooth with an immersion blender. Alternatively, you can blend it in batches with a regular standing blender.
  • Combine the cornstarch with a teaspoon of cold water in a bowl, and stir to form a paste. Add this to the blended soup, and cook on low for 30 minutes to an hour. This will allow the soup to thicken.
  • Add shredded cheese to the soup, a little at a time. Stir to dissolve the cheese completely. Then, add milk and optionally a little butter. Stir to incorporate all the ingredients.
  • Season to taste with salt and pepper if needed, then serve.



  • The cheese tends to blend in better with the soup if you add a little cheese at a time, and then stir until it has melted into the soup. Adding all the cheese at once could result in cheesy lumps which may not be as appetizing.
  • If the cheese doesn’t melt on its own, you can use the immersion blender to make sure that it’s all thoroughly blended.
  • Small broccoli florets cook faster than large florets, so you can cut them quite small to speed up the cooking time.
  • Always leave the lid on the slow cooker while the food is cooking. Removing the lid will allow the heat to escape, and increase the required cooking time.
