Why We Love This 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 StewBaked ZitiCreamy Homemade Mac and CheeseFried ChickenSausage 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 on 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 Spinach Soup with Lemon.

We are sacrificing nothing here!

Frequently Asked Questions

How Long Do Leftovers Last?

You can store the leftovers in an airtight container in the fridge for 3 to 5 days. 

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 chicken and veggie soup 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.

No Lemon Juice In This Soup?

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

Want to Make This Soup Keto?

To make this recipe true keto, use 2 teaspoons glucomannan powder in place of the cornstarch, and use only 1/2 cup chopped carrots.
