Why Lemon Chicken Soup?
Lemon chicken soup offers a delightful combination of zesty flavors and comforting warmth. The lemon brightens the broth, while the chicken and vegetables provide a hearty and nutritious base. It's a fantastic way to enjoy a filling meal without sacrificing your low-carb lifestyle.
The Inspiration Behind the Recipe
Many variations of lemon chicken soup exist, each with its unique twist. This keto-friendly version draws inspiration from classic Greek Avgolemono soup, a traditional dish made with chicken, egg, and lemon. By replacing the traditional rice or orzo with cauliflower rice, this recipe maintains the authentic flavors while keeping the carb count low.
Health Benefits
This soup is not only delicious but also packed with nutrients. Celery and kale are excellent sources of fiber, while kale is also known for being high in iron and antioxidants. Spinach is filled with antioxidants, vitamin K, and iron. Chicken provides lean protein, essential for building and repairing tissues.

- Chicken: Boneless, skinless chicken breasts or thighs provide a lean protein source and flavor the soup base as it simmers. Rotisserie chicken or leftover chicken can also be used to save time.
- Chicken Broth: Use a good quality chicken broth or bone broth for added nutrition and flavor. Homemade or store-bought options are both suitable.
- Lemon: Fresh lemon juice is key to the soup's bright and zesty flavor.
- Vegetables: A combination of onion, celery, carrots, and garlic creates a flavorful aromatic base. Spinach or kale adds extra nutrients and color.
- Cauliflower Rice: This low-carb alternative to traditional rice or orzo provides a similar texture without the added carbs.
- Egg: Whisking an egg into the lemon juice helps thicken the soup and gives it a silky quality.
- Heavy Whipping Cream and Parmesan Cheese: These ingredients contribute to the soup's creamy texture and rich flavor.
- Olive or Avocado Oil: Used for sautéing the vegetables until tender.
- Simple Seasonings: Dried spices and herbs enhance the overall flavor profile. Bay leaf adds brightness to the broth.
- Optional Ingredients: Fresh parsley or green onions can be used as a garnish.
Step-by-Step Instructions
Here are a few variations of the recipe and steps on how to make it:
Version 1
- Sauté the Aromatics: In a large soup pot or Dutch oven, heat olive or avocado oil over medium heat. Add diced onion, garlic, carrots, and celery. Sauté for about 5 minutes, until the vegetables are softened.
- Add Broth and Seasonings: Reduce the heat slightly and sprinkle gluten-free flour over the vegetables, stirring continuously for about 1-2 minutes. Stir in poultry seasoning, celery salt, black pepper, and bay leaf. Cook for another minute to blend the flavors. Gradually stir in the chicken broth while mixing to avoid clumping.
- Simmer the Soup: Add cauliflower rice and bring to a boil, then reduce heat to a simmer. Add the shredded chicken back into the pot. Let the soup simmer for 20 minutes, until the vegetables are tender and the chicken is fully cooked.
- Finish with Lemon: Stir in lemon zest and juice. Taste and adjust seasonings as needed. Serve hot and enjoy!
Version 2
- Sauté the base: Heat the olive oil in a stock pot or Dutch oven over medium heat. Add the shallot and celery and cook, stirring frequently until softened, about 3-4 minutes.
- Combine Ingredients: Stir in the cauliflower rice, chicken bone broth, and water. Increase the heat to medium-high and gently boil until tender, about 7-8 minutes.
- Add Egg Mixture: Whisk in 1/4 cup of the hot stock to a small bowl with the beaten eggs.
- Finish: Discard the bay leaf and adjust seasonings to taste. Serve with lemon slices and chopped fresh parsley or green onions.
Version 3
- Sauté Vegetables: In a large soup pan or dutch oven, heat olive oil on a medium heat. Sauté the onion, carrots and celery until softened.
- Add Chicken and Broth: Add chicken broth and bay leaves and bring to the boil. Add the shredded chicken and let it simmer to soften.
- Prepare Lemon Egg Sauce: In a medium bowl, whisk together the lemon juice and eggs. While whisking, add a ladle or two of the soup broth into the bowl.
- Finish the Soup: Slowly pour the egg mixture back into the chicken soup, stirring continuously. Continue simmering the soup while you stir, until the soup thickens.
Tips and Tricks for the Perfect Soup
- Don't Boil After Adding Egg: Never bring the soup back to a boil after adding the egg mixture, as this can cause the eggs to curdle.
- Adjust Lemon to Taste: We all have different preferences for lemon intensity. Start with a smaller amount and add more to taste until you reach your desired level of zing.
- Use an Immersion Blender (Optional): To thicken the soup and create a creamier texture, use an immersion blender to partially blend some of the chicken and cauliflower rice.
- Temper the Eggs: To prevent the eggs from curdling, slowly whisk a cup of hot broth into the egg and lemon mixture before adding it to the soup. This will gradually raise the temperature of the eggs and prevent them from cooking too quickly.
- Make it Vegetarian: To make this soup vegetarian, simply leave out the chicken and substitute chickpeas or white beans. Use vegetable broth instead of chicken broth.
- Use Pre-cooked Chicken: Save time by using pre-cooked chicken, such as rotisserie chicken or leftover grilled chicken.
Thickening Options
Several options exist for thickening the soup to your desired consistency:
- Heavy Whipping Cream and Parmesan Cheese: These ingredients add richness and thickness to the soup.
- Xanthan Gum: A powerful thickening agent that requires only a small amount. Start with about 1/4 to 1/2 teaspoon for the entire recipe.
- Konjac Flour: Also known as glucomannan, this low-carb thickener is very potent. Start with 1/4 teaspoon for the entire recipe and gradually whisk it into the hot soup.
- Cornstarch or Arrowroot Powder: Mix cornstarch or arrowroot powder with an equal amount of cold water or broth to form a slurry before adding it to the soup. Use arrowroot powder for a Whole30-compliant option.
Serving Suggestions
This keto lemon chicken soup tastes amazing all by itself, making it a perfect quick lunch or light dinner. For a more substantial meal, consider these serving suggestions:
- Side Salad: Serve with a fresh green salad for a complete and balanced meal.
- Cauliflower Rice: Add a side of cauliflower rice to complement the soup and increase the serving size.
- Roasted Vegetables: Enjoy alongside a medley of roasted vegetables, such as asparagus, broccoli, or Brussels sprouts.
- Feta Cheese: Crumble feta cheese over the soup just before serving for an extra burst of flavor.
Storage and Reheating
Leftover soup can be stored in an airtight container in the refrigerator for up to 5 days. For longer storage, freeze the soup in airtight containers for up to 3 months.
To reheat, gently warm the soup over medium-low heat on the stovetop or in short bursts in the microwave, stirring frequently. Be careful not to boil the soup, as this can cause the egg to curdle.
