This Keto Chicken Noodle Soup is delicious, comforting, and the perfect cure-all for whatever ails you. Made with zucchini noodles, it's gluten-free, whole30, keto, and paleo compliant!
This soup can be made the old-fashioned way by boiling a whole chicken or can be made quicker by using shredded chicken (or rotisserie) and store-bought stock.
This healthy keto chicken noodle soup is comfort in a bowl! It's a perfect meal for cold winter nights or when someone is sick.
It has all the classic components - beautifully flavored broth, shredded chicken, & sauteed vegetables. However, I made it with zucchini noodles to keep it low-carb and keto.
It's excellent for sickness because it has natural hydration from the salt, the steam helps clear nasal passageways, and it has immune-boosting nutrition from the carrots, celery, onion, and garlic.
It's also easy to stomach, soothing, and gives you your chicken soup fix without the excess carbs!

Frequently asked questions
No! While I prefer zucchini noodles for chicken noodle soup, feel free to use any noodle you prefer. Cooked spaghetti squash or store-bought noodles can be substituted.
Traditional chicken noodle soup is not gluten-free or keto due to the pasta. However, this recipe is made with zucchini noodles keeping it low-carb and keto.
While I highly recommend using a whole chicken, no, you do not have to make it entirely from scratch. Feel free to use shredded or leftover chicken and store-bought broth.
How to get a clear broth
While the bone broth won't be completely transparent, here are a few tricks I've found to keep the broth clearer:
- Gently simmer (don't boil!) the chicken. There should be steam coming up and the water should be slightly moving, but not boiling.
- Scoop the scum off the surface as it simmers.
- Let the broth settle (or refrigerate overnight). Then gently pour or scoop out the broth, leaving behind the darker broth that sank to the bottom.
- Don’t brown the sautéed veggies. Brown veggies = brown broth!
From scratch - using a whole chicken
While you can use cooked, shredded chicken (or rotisserie) with store-bought or homemade bone broth, making your keto soup from scratch is SO worth it!
It creates a beautiful, flavorful broth and the chicken is a mix of dark and white meat that is tender and juicy - never dry!
Here are the easy steps:
- Simmer (don't boil!) a whole chicken with broth flavorings for 1.5 to 2 hours. The flavorings include onion, garlic, carrots, celery, salt, bay leaf, or whatever else you prefer.
2. Remove any scum that floats to the top and top off the water as needed.
3. Transfer the chicken from the broth to a cutting board and shred it with 2 forks. You won't need all of it. Save the rest for salads and other recipes.
💭Tip: Easily transfer the chicken to a cutting board by using placing the handle of a wooden spoon into the chicken cavity.
5. Use a strainer to separate the liquid broth from the veggies. Set the broth aside.
💭Tip: Clarify the broth to remove excess fat and make it clearer! To do this, refrigerate the broth so the fat hardens on the surface (4 to 8 hours), then scoop it off.
Soup instructions
Start by cutting up an onion, celery, and carrot. Then, spiralize a zucchini.
While carrots aren't always considered keto, they're perfectly fine in small amounts in a soup like this.
If you don't have a spiralizer, you can use a julienne peeler or simply cut the zucchini as thinly as possible.
Or if you're looking to save time, feel free to buy pre-cut frozen zucchini noodles!
Then, add some oil to a large pot and heat over medium heat. Once hot, add onion and garlic and cook for 2 minutes. Add celery and carrots, and cook for 5 minutes or until softened, and don’t let them brown.
Add broth, spiralized zucchini, thyme, basil, oregano, and dill to the pot.
After that, bring to a light boil and boil for 10 to 15 minutes, or until the veggies are tender. Once the zucchini noodles are almost tender, add the shredded chicken just to heat up. Be sure not to overcook the zucchini or it could become mushy!
Add salt and pepper. Then, taste and adjust the seasonings to your liking and serve!
Serving suggestions
This soup is great served as is, or with something (non!) carby such as:
- keto cornbread
- low-carb almond flour dinner rolls
- keto sandwich bread or store-bought Carbonaut sandwich bread (I can find it much cheaper at Sprouts!)
...all served with butter, of course, because butter is amazing!!!
How to store
- Store: Leftover keto chicken soup can be stored in the fridge for 5 to 7 days BUT…. The zucchini can get a little soggy. You can store zucchini noodles separately if desired.
- Freeze: The soup can be frozen for 2 to 3 months IF you freeze before adding the zucchini noodles because freezing ruins the texture of the zucchini.
- Reheat: To reheat, thaw in the fridge overnight. Then, add to a large pot and bring to a light boil. Add the zucchini noodles and boil until tender.
Tips and substitutions
- Be sure to gently simmer (not boil!) the chicken.
- Even though the instructions are for the stove-top, this can also be made in an Instant Pot using the "Saute" setting.
- While I highly recommend making this recipe from scratch using a whole chicken, you can substitute shredded chicken or a store-bought rotisserie and store-bought or homemade bone broth.
- Feel free to substitute the zucchini noodles with any noodles you prefer. Cooked spaghetti squash is also an excellent low-carb alternative to stir in at the end.
