Keto chicken noodle soup is just one of my many “comfort food” keto recipes. If this is your thing, you may also like keto pizza, a tasty keto chicken pot pie with almond flour pie crust, or keto shepherd’s pie. These good-for-you swaps will satisfy the comfort food craving in a delicious and healthy way.

Ingredients & Substitutions

Here I explain the best ingredients for low carb chicken soup, what each one does in the recipe, and substitution options. For measurements, see the recipe card.

Olive Oil – For sauteing the vegetables. You can use avocado oil, or butter if you don’t turn up the heat too high. Veggies – You’ll need carrots, celery, and onion for that classic chicken soup combination. You could add other veggies, such as peas (for low carb but not keto), zucchini, bell peppers, or cauliflower florets. Chicken – You can cook raw chicken breasts or boneless chicken thighs right in the keto chicken soup. If you have leftover pre-cooked shredded chicken in the Instant Pot or baked chicken breast, those also work great. Season the chicken with poultry seasoning for more flavor! If you have more leftover chicken, use it to make a low carb chicken salad next. Chicken Broth – I prefer to buy reduced sodium or make chicken broth from scratch, but regular broth or bone broth would work as well. Italian Seasoning – Make your own Italian seasoning blend in just a few minutes, or simply use store-bought. Bay Leaf – For richer flavor in your low carb chicken soup. Sea Salt & Black Pepper Spaghetti Squash – You can either bake spaghetti squash or microwave spaghetti squash, but will only need 1/2 of the squash. Use the other half to make spaghetti squash carbonara, classic spaghetti squash alfredo, or spaghetti squash pad Thai.

How To Make Keto Chicken Soup

This section shows how to make low carb chicken soup, with step-by-step photos and details about the technique, to help you visualize it. For full instructions with amounts and temperatures, see the recipe card. You can use zucchini noodles, kelp noodles, or shirataki noodles instead of spaghetti squash. You can also omit the squash altogether if you don’t want any kind of noodles (like my noodle-free healthy soup recipe), or add a pound of cauliflower rice in the last couple of minutes.

Storage Instructions

Store: Pour the soup into an airtight container and store in the refrigerator for up to 5 days. Meal prep: You can roast the spaghetti squash in advance to save time. Additionally, you can make the entire soup ahead of time, and it stores well to enjoy later. Reheat: Warm keto chicken soup on the stovetop or in the microwave, until hot. Freeze: I like to freeze it flat in zip lock bags. Once they are solid, you can store them vertically to save space. Another option is to freeze using souper cubes.

What To Serve With Low Carb Chicken Soup

This keto chicken soup makes a great starter before just about any keto dinner, but you can also double the serving size to make it a meal if you like. The best pairings for soup are: Remove the cooked chicken from the pot, shred it, and return to the pot to continue simmering. Don’t overcook to the point where there’s no resistance at all, or the noodles will be mushy.

Low Carb Bread – 90 second bread is the quickest option, but classic white keto bread tastes great on the side, too. You can also try chaffles (garlic parmesan is my fave with keto chicken soup), some keto dinner rolls, or crusty keto garlic cheese bread. Chips or Crackers – Try my easy keto crackers or flax seed crackers. Each needs just 3 ingredients, or you can customize them with spices. Salad – Lighter salad options like a wedge salad or cucumber tomato salad make a light meal with keto soup, or try a chopped antipasto salad for a heartier option.
