Ingredients

Instructions

  • Turn on the Instant Pot and choose the Saute mode. Add the butter, onions, and garlic to the pot.
  • Cook the onions and garlic until the onions start to look a little see-through.
  • Now, it's time to add 3 cups of chicken broth and the frozen broccoli. Give it a good stir and wait for it to start boiling.
  • Lock the lid in place and press the Manual button. Adjust the time to 5 minutes.
  • When the 5 minutes are up, carefully put a dish towel on the valve and do a quick release. This means letting the steam escape quickly.
  • Once the pin drops down, it's safe to open the lid. Add the remaining chicken broth, heavy whipping cream, cream cheese, and spices.
  • Switch the Instant Pot back to Saute mode and wait for the soup to boil.
  • Now, it's time to add the cheese. Slowly pour it in while stirring the soup continuously.
  • Keep stirring until the cheese melts and the soup becomes smooth and creamy.
  • Once the cheese has fully melted, switch the Instant Pot to the Keep Warm setting.
  • Sprinkle the Xanthan Gum on top of the soup and stir it. This will help thicken the soup. Let it sit for about 5 minutes.

Notes

Helpful Tips:
How do I avoid lumpy cheese?
When cheese gets lumpy and grainy, it makes the entire pot of soup taste yucky. You can avoid this common issue with a bit of patience.
  1. Use freshly grated cheese and add it gradually to the soup.
  2. Stir continuously until the cheese is totally melted and smooth.
  3. Avoid overheating the soup.
  4. Use full-fat cheese.
  5. Let the cheese come to room temperature before adding.
Why is my cheese not melting in broccoli soup?
  1. The soup is not warm enough to melt the cheese.
  2. Excessive heat can cause the cheese to become stringy or lumpy.
  3. The cheese was added too quickly to melt properly.
  4. Used the wrong kind of cheese. Not all cheese melts smoothly. Mozzarella is a perfect example of this.
  5. The cheese was too cold, causing the cheese not to melt properly.
