  • Butter: Grass-fed butter adds extra flavor when sautéing onions and garlic.
  • Cream: Makes the soup extra creamy and rich.
  • Onions: They give the soup a subtle roasted flavor.
  • Garlic: The garlic gives the soup the necessary pep.
  • Bone broth: I prefer to use homemade beef bone broth. However, you can also use vegetable or chicken broth.
  • Broccoli: We use fresh broccoli cut into florets. Avoid frozen broccoli, as it will make the soup much thinner and not delicious.
  • Cheese: I use cheddar because this cheese gives the soup an extra tangy flavor. However, you can also use milder cheeses like Gouda. The quality is even better, and it’s usually cheaper if you buy a block and grate the cheese.

How to Make Keto Broccoli Cheese Soup

The instructions below will explain step-by-step how to make keto broccoli cheese soup.

See the recipe box below for an overview, including ingredients, quantities, and temperatures.


  • Sauté: Melt butter in a large pot over medium heat. Add onions and garlic once the pot is hot. Sauté, stirring, for 1-2 minutes.
  • Simmer: Add bone broth, cream, broccoli, pepper, and salt, and bring soup to a boil. Let it simmer for about 15 minutes until broccoli is tender.
  • Blend: Add the grated cheddar step by step and mix the soup well. Take the soup off the heat and serve.
  • Puree (optional): The classic recipe uses whole broccoli florets. However, you can also puree them for a thicker and even creamier soup. To do this, puree the finished soup in the pot with a hand blender.

Tips for the Perfect Soup

  • Broccoli: The broccoli florets should be small. The cheese is more likely to stick to larger pieces.
  • Temperature: the heat should be low when adding the cheese. If it gets too hot, the cheese can stick and clump.
  • Cheese: Add the cheese very slowly. If you add all the cheese at once, it will clump.
  • Stir: Do not stop stirring while adding the cheese.
