Ingredients:
For the Keto Noodles:
- 1 cup shredded fresh mozzarella
- ¼ teaspoon xanthan gum
- 1 large egg yolk
For the Keto Chicken Soup:
- 2 tablespoons olive oil (or avocado oil)
- 1 cup chopped carrots (peeled; optional, see Notes)
- 1 cup chopped celery (optional, see Notes)
- 1 cup diced yellow onion (optional, see Notes)
- 4 cloves garlic, minced
- 1 quart chicken broth (4 cups or 32 ounces, see Notes)
- 2 bay leaves
- ½ teaspoon dried thyme
- ½ teaspoon dried oregano
- 1 teaspoon freshly ground black pepper (adjust to taste)
- 2 cups cooked, shredded chicken (see Notes)
- 1 tablespoon fresh lemon juice
- Chopped fresh parsley (optional, for garnish)
Instructions:
For the Keto Noodles:
- Melt the Cheese: Place the shredded mozzarella cheese in a microwave-safe bowl. Microwave in 20-second increments, stirring between each, until fully melted (about 1 minute total).
- Make the Dough: Once the mozzarella is melted, remove the bowl from the microwave. Add the xanthan gum to the melted cheese and mix with a fork until a ball forms. Allow the cheese to cool slightly, then add the egg yolk. Mix until the dough becomes smooth and fully incorporated.
- Roll the Dough: Lay a large sheet of parchment paper on a flat surface. Place the dough ball on the parchment and cover with a second sheet of parchment paper. Roll out the dough into an even sheet about ⅛-inch thick.
- Cut the Noodles: Remove the top layer of parchment paper and use a knife or pizza cutter to cut the dough into strands that are approximately ½-inch wide and 3 inches long. Transfer the noodles to a plate and set aside.
For the Keto Chicken Soup:
- Sauté the Vegetables: Heat a large pot over medium heat and add the olive oil. Once the oil is hot and shimmering, add the carrots, celery, and onion. Stir occasionally and sauté for 7 minutes or until the vegetables begin to soften.
- Add Garlic: Add the minced garlic to the pot, stir to combine, and sauté for another 1-2 minutes until the garlic becomes fragrant.
- Simmer the Soup: Pour in the chicken broth, add the bay leaves, thyme, oregano, and pepper. Stir to combine and bring the liquid to a gentle boil. Once boiling, reduce the heat slightly and cook for 5 minutes until the vegetables are tender.
- Add the Chicken and Lemon Juice: Stir in the shredded chicken and fresh lemon juice. Let the soup simmer for 1-2 minutes until the chicken is heated through.
- Add the Noodles: Add the prepared keto noodles to the pot and simmer for an additional 1-2 minutes, or until the noodles are tender.
- Serve: Remove the soup from heat and ladle it into bowls. Garnish with freshly chopped parsley and serve warm.
Why You’ll Love This Recipe
This Keto Chicken Noodle Soup is the ultimate comfort food with a low-carb twist!

Tips
- Xanthan Gum: Be sure to add the xanthan gum slowly and mix it well with the mozzarella to avoid clumping. It helps bind the dough and gives the noodles the right texture.
- Vegetables: The carrots, celery, and onion are optional, but they add a lot of flavor and nutrients to the soup. If you’re looking for a more keto-friendly option, you can skip the carrots and onion to reduce carbs.
- Shredded Chicken: For convenience, you can use rotisserie chicken or any leftover chicken you have. Just ensure it’s cooked and shredded before adding to the soup.
Variations and Substitutions
- Low-Carb Vegetables: If you prefer a more keto-friendly version, you can substitute the carrots and onions with other low-carb vegetables like zucchini or mushrooms.
- Herbs and Spices: Feel free to adjust the seasoning to your taste. You can add extra garlic, parsley, or even a pinch of red pepper flakes for a little heat.
- Keto Broth: If you want to make the soup even richer, you can use bone broth instead of regular chicken broth for additional collagen and nutrients.
FAQs
Can I make this soup ahead of time?
Yes, you can prepare the soup in advance and store it in the fridge for up to 3 days. However, the noodles may become soft after storing, so you might want to cook them separately and add them when reheating the soup.
Can I freeze this Keto Chicken Noodle Soup?
It’s best to freeze the soup without the noodles, as the noodles may become mushy after freezing. You can freeze the soup base and then prepare the noodles fresh when you’re ready to serve.
What if I don’t have xanthan gum?
If you don’t have xanthan gum, you can try using psyllium husk powder or almond flour to help thicken the dough, but the texture may differ slightly.
Serving
Serve this keto chicken noodle soup as a comforting main dish for lunch or dinner. It pairs wonderfully with a simple side salad or keto-friendly crackers. If you like, you can garnish the soup with extra herbs, a squeeze of lemon, or a dollop of sour cream for added richness.
Suggestions
- Toppings: You can top the soup with extra freshly chopped parsley, shredded cheese, or a dash of hot sauce if you like a little heat.
- Side Dishes: Pair this soup with a fresh green salad or keto garlic bread for a complete meal.
