Why We Love Lemon Chicken Soup

  • This lemon chicken soup recipe has a full-bodied, rich flavor!
  • We switched out the carb-laden pasta for cauliflower rice!
  • The perfect blend of seasonings is highlighted with just a touch of citrusy lemon juice!
  • Serve on a chilly night or as a late afternoon lunch with an easy dinner roll, or some crunchy tortilla chips. Don’t forget the butterscotch haystacks for dessert!

Ingredients and Variations

VEGETABLES One of each of an onion, a carrot, and a stalk of celery are all you need, but you can add whatever veggies you have on hand, add fresh dill for a boost in flavor or even a bag of frozen spinach or green beans will add color and flavor!

BROTH This super creamy broth has just the right combination of healthy fat, herbs, and seasonings and is punctuated by the bright addition of lemon juice.

MEAT This is a great way to use up leftover meat, especially ground sausage, turkey, or chicken!

RICE This recipe uses cauliflower rice for a healthy spin on this soup. Swap cauliflower rice for instant rice or cooked orzo.
