  • 2.5 cup chopped broccoli
  • 3 ounce shredded carrots
  • 1/2 diced onion
  • 3 clove chopped garlic (sub for 1 TB minced garlic)
  • 2 tablespoon butter
  • 1 cup chicken broth
  • 1/2 cup heavy cream
  • 4 ounce full fat cream cheese
  • 1 cup shredded sharp cheddar cheese (112g weighed out)


  • Dice onion and chop up broccoli as fine as you'd like. I chopped roughly in this recipe
  • In a large pot on medium high heat add butter and diced onion. Once fragrant add in chopped garlic. Note, in the video I used chopped garlic. I now feel grating the garlic over the soup before covering with a lid is the best method.
  • Pour in chicken broth, lower the heat and bring to a simmer. Add in cream cheese and heavy cream.
  • Add in chopped broccoli and carrots and bring to a simmer then cover. Check in every few minutes to make sure it's a slow simmer and to check the tenderness of broccoli.
  • Once broccoli is tender toss in shredded cheese and mix in until all melted. Season with salt and white pepper. Taste for seasoning then serve while hot.
  • Crockpot and instapot instructions in notes below.


Helpful Recipe Tips

  • Simmer never boil, when dealing with dairy, too much heat can cause it to curdle. The important part is the slow simmer and the reduction of the broth to allow the sauce to be creamy.
  • Optional carrots, the carrots don't have to be added into the soup to make it delicious. Net carbs aren't an issue with the carrots because without them the soup is only 6g net carbs per serving.
  • Freshly shredded cheese only, using the package shredded cheese it won't mix well due to the non-caking agent. It will cause the sharp cheese to sit on top and not mix in with the cream sauce.

Crockpot Instructions

With a crockpot on high heat add all ingredients except the cheddar cheese. Cook down and reduce about an hour until broccoli is tender. Add in cheddar cheese and cook about 15 minutes then serve. Taste and season with salt and white pepper.

Instant Pot Instructions

On sauté setting, add in butter, diced onion and garlic. Once fragrant pour in chicken broth, heavy cream, cream cheese, broccoli and carrots. Place on high pressure, close lid and cook for 7-10 minutes. Open and add cheddar cheese mix around until melted then taste and season with salt and white pepper until flavor is perfect.
