Our Keto Broccoli Cheddar Cheese Soup recipe is very high in electrolytes, sodium, and potassium to keep you at your best. This is a very easy cheese and broccoli soup recipe that will not only deliver a big dose of nutrients but keep you fueled for a good part of the day.
The secret to this cheddar cheese soup is roasting the broccoli, which gives a rich caramelized flavor adding depth and character to the dish.
You can forgo the roasting, but in my opinion, the extra time is worth the added flavor in the soup.

I have made this several times, it is so delicious!! Best soup to have when you aren’t feeling great. I ate today and it was hot outside, good anytime. The flavors are perfect. Thanks for the recipe!!
This is one of the most delicious soups I have tasted in a long time. I made it 50/50 broccoli and cauliflower, and substituted some of the cheddar cheese with a tangy blue cheese. I made double the quantity so that I can freeze it for a quick, ready meal.
This soup is truly amazing. I fixed it today for my husband and he loved it as well. Thanks for the recipe. It will be on the menu again in my house hold.
Thank you for your kind words, Amy! I’m so glad that you and your husband enjoyed it.
