This creamy Chicken Spinach Soup is the perfect Instant Pot keto comfort food! Under 5 net carbs per bowl, this low carb soup will become a family favorite and keto meal prep staple.
The keto lifestyle can be a bit difficult during soup season! It’s easy to fill up on fresh produce in the summer, but cold weather makes me wish for all my old favorites. I’ve done a lot better now that I’ve come up with an Easy Keto Chili and this Lobster Bisque. I still wanted a more traditional chicken soup, though… And this Chicken Spinach Soup hit the perfect balance! It’s creamy, comforting, packed with healthy vegetables, and still low in carbs.
Ingredients for Chicken Spinach Soup
As always, here is a quick overview of the ingredients used in our Chicken Spinach Soup. For the complete recipe, just scroll to the bottom of the page.
- Chicken – I used boneless, skinless chicken breast, but you can use any cut you prefer.
- Olive oil – Butter, avocado oil, coconut oil will also work
- Chicken broth
- Heavy cream
- Vegetables – Celery, Onion, Carrot, Garlic, Zucchini, Spinach
- Spices- Italian seasoning, garlic powder, onion powder, thyme, salt and pepper
How to make Instant Pot Keto Soup
First, turn your Instant Pot to “sauté” and add the olive oil (or butter), celery, onion, carrot and garlic. Sauté 3-4 minutes or until softened. Turn off the sauté function and add the chicken, spices and broth to the Instant Pot. Secure the lid, then set the timer for 12 minutes.
Note: You could use more than two pounds of chicken if you prefer! If you are halving, doubling, or altering the amount of chicken you are using, simply cook for 6 minutes per pound of meat. For example, doubling this recipe would require 24 minutes of pressure cooking time.
Once the timer has gone off, allow your Instant Pot to naturally release the pressure for ten minutes. Release any pressure that may remain and open your pressure cooker. Remove the chicken and set it to the side. Add the zucchini, heavy cream and spinach to the soup and stir well. Put the lid back on the pressure cooker- the residual heat will cook the vegetables while you are shredding the chicken.
Shred your chicken into bite size pieces and add back to the soup. Stir well and season with any additional salt and pepper you want. I recommend garnishing with parmesan cheese! If you love adding a bit of extra texture and flavor, check out this list of Keto Soup Garnish & Topper Ideas!
What are the best greens for soup?
Spinach is a great option for soups because the flavor is mild, its affordable and easily available. If you are interested in using a darker green, like kale, just be sure to remove the stems before adding to your soup.
Is soup good for keto meal prep?
Yes! I love using soup for meal prep- it’s the perfect keto comfort food! If you are making this soup ahead of time, simply store in a glass or plastic container with an airtight lid and place in the fridge. This soup will stay fresh in the fridge for up to four days. This chicken spinach soup can also easily be frozen. Let your soup cool and pour into a plastic bag. Lay flat in the freezer, where it will be good for up to four months. If storing in a plastic or glass container in the freezer, make sure to leave room for the soup to expand during freezing.
To reheat, simply simmer in a pot on the stove, microwave by the bowl, or dump the entire thing in a slow cooker on low!
What to serve with Chicken Spinach Soup
I personally love some rolls with my soup- these Keto Cheddar Garlic Biscuits are so satisfying. My husband loves these Rosemary Garlic Keto Rolls, which would pair perfectly with this Instant Pot keto soup. We also love to serve a little salad before our soup… This Chopped Italian Salad is a favorite in our house! My go-to side is this Cheesy Cauliflower Casserole– my family eats every bite!
