The Ultimate Keto Avgolemono: My Go-To Greek Lemon Chicken Soup

That one small step was a total game-changer. It removed the excess moisture and gave the cauliflower a nutty, savory flavor that perfectly complemented the broth. Now, this Keto Avgolemono is one of my all-time favorite comfort foods. It’s rich, creamy, and packed with bright, zesty lemon flavor, all without the carb-crash. It’s the kind of meal that feels like a warm hug in a bowl, and I am so excited to share it with you.

• Perfect for Any Occasion: This soup is elegant enough to serve to guests but simple enough for a cozy weeknight dinner. Plus, it’s fantastic for meal prep!

A Closer Look at the Ingredients

Here’s what you’ll need to bring this amazing soup to life.

• Olive Oil: A good quality extra virgin olive oil adds a touch of fruity, peppery flavor right from the start.
• Riced Cauliflower: Fresh riced cauliflower has the best texture, but frozen works in a pinch! Just be sure to thaw it and squeeze out any excess water before toasting.
• Low-Sodium Chicken Broth: Using low-sodium broth is key because it lets you control the final saltiness of the soup.
• Chicken Breasts: Boneless, skinless breasts are lean and shred beautifully. If you prefer darker meat, thighs work wonderfully too.
• Egg Yolks: These are the secret to the soup’s signature creamy texture. Don’t skip them!
• Veggies: A classic mix of onion, celery, and carrot (a mirepoix) builds a sweet, aromatic foundation.
• Lemon Juice: Freshly squeezed is non-negotiable! The bright, zesty flavor is the star of the show.
• Herbs & Spices: Fresh parsley and thyme add an earthy freshness that cuts through the richness, while a pinch of turmeric gives the soup its gorgeous golden hue.

Step-by-Step Instructions

1. Sear the Chicken: In a large pot, heat one tablespoon of olive oil over medium-high heat. Pat the chicken dry and season it well with salt and pepper. Sear for 3–4 minutes per side until you have a beautiful golden-brown crust. This step builds a ton of flavor. Remove the chicken to a plate.

2. Build the Aromatic Base: Reduce the heat to medium and add the remaining olive oil. Add the onion, celery, and carrot. Sauté for 10–12 minutes, stirring occasionally, until the vegetables are completely softened and sweet. This patience pays off in the final flavor. Stir in the minced garlic and fresh thyme and cook for one more minute until fragrant.

3. Simmer the Soup: Pour in the chicken broth, scraping up any delicious browned bits from the bottom of the pot. Return the seared chicken to the pot, bring to a gentle boil, and then immediately lower the heat. Cover and simmer for 20 minutes, or until the chicken is cooked through.

4. Toast the Cauliflower: While the soup simmers, heat a separate, dry skillet over medium heat. Add the riced cauliflower and toast, stirring frequently, for 5–7 minutes until it’s dry and lightly golden. This step is crucial and prevents a watery soup!

5. Shred and Combine: Carefully remove the cooked chicken from the pot. Use two forks to shred it into bite-sized pieces, then stir the shredded chicken and your perfectly toasted cauliflower rice into the soup.

6. Create the Lemon-Egg Emulsion: In a mixing bowl, whisk the egg yolks, fresh lemon juice, and turmeric together vigorously. Keep whisking until the mixture is pale yellow and frothy.

7. Temper and Thicken: Now for the magic. Turn the heat off under the soup pot. While whisking constantly, slowly ladle about two cups of the hot broth into the egg-lemon mixture. Adding the hot broth gradually and whisking prevents the eggs from scrambling. Once it’s all combined, pour this warmed mixture back into the main pot, stirring the whole time. You’ll see the soup instantly turn creamy and opaque. Do not return the soup to the heat!

8. Finish and Serve: Stir in the fresh parsley, taste, and add any extra salt and pepper if you think it needs it. Serve immediately and enjoy that velvety goodness.

Expert Tips for Success

• Storage: Leftovers are fantastic! Store them in an airtight container in the fridge for up to 3 days. Reheat gently on the stovetop over low heat. Never boil the leftovers, as it can cause the soup to separate.
• Substitutions: For a richer, more decadent soup, feel free to use boneless, skinless chicken thighs instead of breasts. You can also swap the parsley for fresh dill for a more traditional Greek flavor profile.
• Troubleshooting: If your soup curdles, it means the broth was too hot when you added the eggs, or the soup boiled afterward. The flavor will still be great, but the texture won’t be as smooth. The key is to take the pot completely off the heat before you start tempering.

Serving & Pairing Ideas

This soup is a complete meal on its own, but it’s also lovely paired with a simple green salad with a light vinaigrette. For those not strictly counting carbs, a piece of crusty bread for dipping is heavenly. For a drink pairing, a crisp, dry white wine like a Sauvignon Blanc or Pinot Grigio cuts through the richness beautifully.
