Keto Broccoli And Cheese Soup

This is the BEST Keto Broccoli  And Cheese Soup recipe I’ve ever tried! There is a small difference in this recipe that makes a world of difference in the taste. Once you make it this way, you will never make it any other way. Promise! Keto broccoli cheddar soup is one fantastic creamy soup to serve up.

Keto Broccoli Cheddar Soup

The secret to this recipe is a small amount of hot sauce and a bit of garlic. Grandma taught me long ago that any time you make a cheese dish of any kind, you always add a small amount of hot sauce. It compliments the flavor of the creamy rich cheese! Grandma did this with her cheesy mac & cheese bake recipes too!

Now, I need to tell you that it’s not spicy at all. You won’t really notice the hot sauce itself but you will notice the creamy intense cheese flavors this soup has. Gosh, it’s good!

OH!  And… the cream cheese in this recipe adds a level of creaminess that will blow your socks off!
