Equipment

Ingredients

  • 4 cups organic chicken broth
  • 1 head broccoli cut into florets (about 4 cups)
  • 1 cup heavy cream
  • 1 cup cheddar cheese shredded plus more for topping

Instructions

  • Bring the chicken broth to a boil.
  • Add the broccoli florets. Simmer on medium for five minutes or until broccoli is bright green and tender.
  • Add cheese a little at a time to give it time to melt.
  • Turn heat to medium-low. Then, add heavy cream in quarter cup increments to avoid curdling.
  • Use an immersion blender to blend all ingredients to your liking.
  • Allow soup to simmer for another five minutes on low heat until you achieve your desired thickness.
  • Ladle into bowls.
  • Top with extra chunks of cheese leftover broccoli florets, if you have any. Enjoy!

Notes

If you want to take this simple broccoli and cheese soup up a notch, try sauteeing freshly chopped garlic and onions in butter as your first step. Then add your chicken broth to this mixture and continue from there.
You can also add different proteins to the soup. For instance, add chopped rotisserie chicken into the soup after you've blended it for a heartier, meatier soup. Or top with leftover air fryer bacon.
To lower the carb count on this soup, try using cheeses that are naturally lower in carbohydrates. This includes goat cheese and feta cheese.
If your soup isn't thickening, add in one teaspoon of xanthan gum just before blending.
Instead of making this soup on the stovetop, you can make it in your Instant Pot. Here are the steps:
  1. Pressure-cook broccoli with broth until done.
  2. Use your immersion blender to blend broccoli and broth.
  3. Mix in the cheese and cream.
  4. Serve and enjoy your comforting low-carb soup.
