Keto Broccoli Cheese Soup Cooking Tips

Here are a few tips to help ensure that your keto broccoli cheddar soup is amazing.

Fresh or Frozen Broccoli

While my favorite is fresh broccoli, let’s face it – frozen broccoli is keto KING! The key to making this soup perfect to your liking is all in the broccoli.

If using frozen broccoli, it maybe easier to steam in the microwave first and then transport to your soup pan to melt with butter.

Not a Broccoli Fan?

While I love broccoli, my son doesn’t. BUT I will say, he LOVES this soup. When I know that he is eating it, I’ll cook the broccoli extra so isn’t as obvious sight-wise.

Best Cheese to Use

To prevent clumping and hidden carbohydrates – we recommend using a natural cheese and shredding yourself. Tillamook cheese works great.

While we love the convenience of shredded cheese – often there are hidden carbs and additives that come along with bagged cheese. These do not help the cooking situation when making this soup.

Xanthan Gum Alternative

Yes, xanthan gum is a random product that if you haven’t purchased before – may not be in your pantry. In our keto broccoli cheddar soup recipe – we are using xanthan gum to help thicken the broth.

No xanthan gum, no problem! You can use a 1:1 ratio and replace with corn starch – though do know corn starch has around 7 carbs per tablespoon.

And if you want to totally skip the xanthan gum, that’s okay too! Your broccoli cheddar soup maybe a little more runny but no worries.

Cream Cheese Suggestions

To help the cream cheese, well cream the soup – we recommend that it be at room temperature before putting in the soup.

Substitute Cottage Cheese

If you don’t have cream cheese, an alternative could be cottage cheese – though the taste will differ from the original keto soup recipe.

Thicker Soup

We suggest 2 ounces of cream cheese, but for a creamer thicker soup – feel free to add in more cream cheese (4 ounces.)

  • Broccoli - 8 Ounces
  • Natural Shredded Cheddar Cheese - 4 cups
  • Butter - 2 TBSP
  • Heavy Whipping Cream (HWC) - 1 cup
  • Water - 1/4 Cup
  • Cream Cheese - 2 ounces
  • Garlic - 1 clove
  • Salt - 1/2 TSP
  • Black Pepper - 1/4 TSP
  • Onion Powder - 3/4 TSP
  • Paprika - 1/2 TSP
  • Ground Mustard Seed - 1 TSP
  • Vegetable Broth - 6 cups
  • Xanthan Gum - 1 TBSP


  1. Wash then chop broccoli into bite size pieces - a quick blend in the food processor can speed up this process.
  2. Shred the cheddar cheese, we will use that in just a few steps.
  3. Set your cream cheese out on the counter, as it is best if its used when softened or at room temperature.
  4. If you are using a fresh garlic clove, mince your garlic.
  5. Melt your butter into a large soup pot using medium heat. Once melted, stir in broccoli.
  6. Add in your minced garlic and the 1/4 cup of water. Next, cover your pot with a lid.
  7. Cook broccoli in covered pot for approximately 5 minutes, or until it's soft. We will cook the broccoli more in a later step but this gives the vegetable a good cooking start. Stir occasionally so it doesn't burn.
  8. Once broccoli is cook to soft, add in your heavy whipping cream and all of the seasonings (salt, pepper, onion powder, paprika, ground mustard seed)
  9. Stir all soup ingredients together. Bring the cream to a simmer and cook for approximately 5 minutes - stirring as needed.
  10. Pour the vegetable broth into the soup mixture. Cover the pot and bring to a boil. Reduce to a simmer and cook until the broccoli is extremely tender. This will take around 15-20 minutes.
  11. Chop up the cream cheese block into small pieces. Remember, it's best if the cream cheese is at room temperature.
  12. Keeping your soup base on low, stir cream cheese into your soup allowing it to melt.
  13. After the cream cheese has melted thoroughly in the soup - let's add the cheddar cheese. Slowly sprinkle in the shredded cream cheese. We add in only about 1/2 cup at a time. Stir until the cheese is completely melted into the soup.
  14. Remote a half cup of the soup broth and mix with the xanthan gum in a separate bowl. Pour the bowl back into the soup mixture. The xanthan gum helps thicken the broccoli cheddar soup. Keep reading to find a xanthan gum alternative and more tips for making our low carb broccoli cheese soup.
