Creamy Chicken Soup Recipe

There’s nothing I love more in the dead of winter, than a big steaming pot of chicken soup.

Good chicken soup is always piping hot, chunky, and herbaceous, with the quintessential flavor of healing and comfort. What’s not to love?

This year we’re focusing on going back and “filling in the gaps” here on A Spicy Perspective, where down-home favorite recipes are missing.

We’ve added things like… Brunswick Stew, Baked Ziti, Creamy Homemade Mac and Cheese, Fried Chicken, Sausage Gravy, and Lemon Crinkle Cookies.

And after 10 years of recipe sharing, we just recently posted our Best Chicken Noodle Soup Recipe.

Although most of the recipes we’ve added are cozy and carb-heavy, we’re also sharing comforting low carb classics as well!

If you’re keeping the carbs on the down-low right now, today’s Creamy Lemon Chicken Soup with Spinach, Lemon, and Parmesan will be a huge hit on your dinner table!

Lemon Chicken Soup For the Win

I’m a big fan of Greek-Style Lemon Chicken Soup with orzo or couscous, and a heavy spoonful of crumbled feta cheese.

Today’s Creamy Chicken Soup with Lemon is a low-carb play off the Mediterranean flavor profile. However, we’re holding the pasta, and adding in tons of veggies and cheese instead.

Rather than using feta cheese in this Creamy Low Carb Chicken Soup, we’ve added a generous portion of shredded parmesan cheese, so it melts and blends into the creamy soup base.

With a bright rich lemon-parmesan flavor and quick cook-time, this easy chicken soup recipe is a show-stopping family favorite you can whip up any night of the week!

Keto Chicken Soup with Lemon

Low Carbers… I’ve got you covered.

This bold and tantalizing creamy chicken soup recipe is packed with protein and veggies, while keeping the carbs at a minimum.

You have the option to use glucomannan powder for thickening, which contains only 1 gram carbohydrate per servings. (Cornstarch adds about 4 grams per serving.)

Glucomannan powder is a powerful thickener, so you only need to use 2 teaspoons to thicken the whole pot of soup!

Furthermore, if you follow a strict ketogenic diet, you can cut the carrots in half to take the carbs down even further.

If your dietary restrictions aren’t a major concern, you will still love the zesty flavor and luxurious texture of this Low Carb Chicken Soup with Lemon.

We are sacrificing nothing here!

Creamy Chicken Soup FAQ

Can I Freeze This Creamy Chicken Soup?

Yes and no. Yes, you can freeze it. However, sometimes when people reheat frozen soups containing cheese, the cheese separates and curdles.

To avoid this, reheat the soup at a low temperature, and do not let it boil.

Can I Use Arrowroot Powder For Low Carb Chicken Soup?

Arrowroot powder is a fabulous grain-free thickener, but it doesn’t actually reduce the carbs more than cornstarch.

Instead, try using glucomannan powder to thicken the soup to keep the carb very low.

Is This A Gluten-Free Chicken Soup Recipe?

Yes! Both thickening options are gluten-free, therefore the entire recipe is as well.

Can I Swap Out the Vegetables In This Lemon Chicken Soup Recipe?

Of course! Add or omit anything you like. Just remember, if it’s a hard dense vegetable, it should be sauteed with the onions at the beginning.

A Low Carb (Keto) Creamy Chicken Soup Recipe with Lemon, Parmesan, and Spinach!
Servings: 8


  • 2 tablespoons butter, or olive oil
  • 1 large sweet onion, peeled and chopped
  • 1 cup chopped celery
  • 1 cup chopped carrots
  • 5-6 cloves garlic, minced
  • 1 pound boneless chicken breasts
  • 2 teaspoons lemon zest
  • 1 tablespoon Italian seasoning
  • 8 cups chicken broth
  • 1/2 cup heavy cream
  • 1/4 cup cornstarch (2 tsp glucommanan powder for keto)
  • 1 cup grated parmesan cheese
  • 1 cup baby spinach, packed
  • 1/4 cup chopped parsley
  • salt and pepper


  • Place a large 6-8 quart saucepot over medium heat. Add the butter, onions, and celery. Sauté for 3 minutes. Then add in the carrots and garlic and sauté another 2 minutes to soften.
  • Place whole raw chicken breasts in the pot. Add in the lemon zest, Italian seasoning, chicken broth, 1 teaspoon salt, and 1/4 teaspoon black pepper. Cover and bring to a boil. Lower the heat if needed and simmer for about 15 minutes (covered) to cook the chicken.
  • Meanwhile, whisk the heavy cream and cornstarch (or glucomannan) together until very smooth.
  • Once the chicken has cooked through, pull the chicken breasts out of the pot with tongs and set on a cutting board.
  • Stir the heavy cream mixture and parmesan cheese into the soup base to thicken. Stir another minute, until the parmesan melts and blends smoothly into the soup base.
  • Use two forks to shred the chicken breasts. Then stir the shredded chicken, spinach, and parsley in the soup. Taste, then salt and pepper as needed. Serve warm, with extra parmesan if desired!


This recipe only calls for fresh lemon zest. If you want a stronger lemon flavor, add 1-2 tablespoons of juice at the end.

  2. Also, I didn’t have cornstarch and used ground flax!!!

  3. I used bone in chicken thighs and served with a lemon slice and sprinkle of Parmesan…omg so delicious!!!!

  4. Add 2 tsp of goya white cooking wine after sautéing onions and garlic. This was delicious.

  5. This looks amazing. I can’t wait to try it. I am thinking of using an egg to thicken like in Greek avgolemono soup. What do you think?

  6. such a great recipe! i did add a cup of orzo for the kids. Yum!

  7. P.S. My mom just asked me how I’d rate something. I said most people use the 5-star system. She said well I’d give this 5+! So, it was pretty darn tasty.

  8. I tried this recipe it has great flavor! I skipped carrots because I had none. I added medium size chunks of 1 zucchini toward the middle/end of simmering just because I found that I like zucchini in my chicken noodle soup. I forgot the parsley and added more spinach and more parmesan cheese. I also did add the juice of half of the lemon at the end because I didn’t taste the zest as strong as I thought. I’d make it again! Great cold weather recipe. Something different from your “everyday” chicken noodle soup. Thanks!
