Keto Slow Cooker Greek Lemon Chicken Soup

My Keto Slow Cooker Greek Lemon Chicken Soup, or Avgolemono soup,  is a creamy soup that will keep you warm on chilly winter nights.

And since it’s made in the slow cooker, you don’t have to stand over a hot stove for hours while it cooks.

Plus, it’s completely Keto and dairy-free, which means you can enjoy the soup without any worry of sneaky carbs ruining your diet.

Even better, your entire family will love it and no one will know it’s Keto (unless you tell them, of course).

Recipe Modifications and Cooking Tips

My Keto Slow Cooker Greek Lemon Chicken Soup Recipe is already incredibly easy to make, but here are a few modifications and cooking tips to make this even easier and to accommodate the ingredients you might already have in your refrigerator or pantry.

  • You can skip sauteing the onion, celery and garlic before adding them to the slow cooker, but it really helps to deepen the flavor of the soup.
  • You can cut the raw chicken into bite-sized pieces before adding it to the slow cooker. It will taste just as good, and you can save yourself from chopping the chicken after it’s cooked.
  • Boneless chicken breast can be used instead of thighs, and you don’t even have to adjust the cooking time.
  • You can use bone-in chicken thighs or breast, but the cooking time might be a bit longer. Be sure to use an instant-read thermometer to check that the chicken reaches an internal temperature of 165 F (75 C). If you use bone-in chicken, be sure to remove and discard the bones before serving!
  • You can use frozen cauliflower “rice” but be sure to defrost it before adding it to the slow cooker. Also watch to make sure you don’t buy seasoned cauliflower “rice” because it will alter the taste of the soup.
  • The eggs are what gives this soup it’s creamy texture, and it’s really important to slowly pour the soup into the egg and lemon mixture while continuously stirring in step 6. Otherwise, the eggs might scramble, which will result in a soup similar to egg drop soup!
