  • Adaptable: Don’t have this or want to add a little more of that.. go for it.
  • They’re economical. The Keto diet can be expensive with its emphasis on organic protein, but soups and stews allow you to stretch your ingredients.
  • They’re quick. There are not many pre-made convenience foods available on the Keto diet, but many of the keto soups and stews can be ready in under 40 minutes making them the perfect weeknight dinner.
  • They’re great for meal-prep and make ahead meals. Make them ahead or make a big batch and then pack them up for the perfect lunch on the go. Several recipes include slow cooker options as well.
  • They’re scalable. Have a big family… double the recipe. Cooking for just yourself… then make half. Most of these recipes can be adjusted very easily.
  • They’re accessible. No weird ingredients you’ve never heard of or will never be able to find. You’ll be familiar with all of the simple ingredients, which will be really comforting when you are adjusting your nutritional plan. And no fancy equipment is needed for keto recipes. If you have a large pot you are good to go!

Key Ingredients For This Chicken Keto Soup Recipe

the ingredients for this recipe with labels
  • Avocado Oil: A neutral cooking oil. If you don’t have avocado oil, you could substitute olive oil.
  • Celery and Onions: Finely chopped. Make sure to stick to the allotted amount of onion in this recipe as onions are to be used in moderation for the keto diet.
  • Kosher Salt and Black Pepper
  • Garlic: Minced garlic is the perfect addition for any cold weather soup!
  • Fresh Herbs: Thyme and Paprika
  • Chicken Broth: Buy it premade chicken broth or bone broth or make your own
  • Boneless Skinless Chicken Thighs: Cubed
  • Cauliflower Rice: you can use thawed frozen cauliflower rice, refrigerated (sold in bags in the produce department) or make your own. Carolyn suggests that we can sub in zoodles for Keto Chicken Noodle Soup!

How To Make Keto Soup with Chicken & Cauliflower Rice

cook the vegetables, add the seasoning then add broth, chicken and cauliflower
  • Step 1: Sauté the onion and celery to soften them.
  • Step 2: Add in the aromatics and let them bloom in the hot oil. This will help bring out the flavor of the garlic, thyme and paprika.
  • Step 3: Then stir in the broth and then add the chicken and riced cauliflower and simmer until cooked through.

Expert Tips and Tricks For This Low-Carb Chicken Soup Recipe

Low Carb Soup Substitutions and Variations

  • To turn this keto soup recipe into a low-carb chicken noodle soup, just replace the cauliflower rice with zoodles or low-carb noodles of your choice! I love the idea of adding zucchini noodles!
  • Instead of boneless chicken thighs, you can also use chicken breast or a rotisserie chicken. We like to keep shredded chicken on hand for an easy protein source. I simply cook it in the Instant Pot with a bit of broth for 20 minutes, then shred it with two forks. Stir it into the soup, and heat through.
  • We added on some parsley for a bit of color, but feel free to omit it if you don’t have any on hand.
  • You can also add a teaspoon of chopped rosemary with the aromatics for more flavor.

How to Make the Cauliflower Rice From Scratch

  1. Cut the cauliflower in half and remove as much of the stem and leaves as possible. Then, cut the cauliflower into small florets removing any of the remaining stem. Place the cauliflower florets in a food processor or blender and pulse just until the cauliflower is broken down into small rice sized pieces.
  2. If you don’t have a food processor or blender, grate the cauliflower on the large holes of a box grater after cutting in half and removing the stems and leaves.

You can also use purchased fresh or frozen cauliflower rice to save time!

Keto Friendly Serving Suggestions For Soup

Storing Low Carb Chicken Soup

  • Leftovers: leftovers can be kept in the refrigerator up to five days.
  • Storage Tip: Make sure to cool the soup before closing the resealable container.
  • Freezing: Freeze up to two months. For best texture omit the cauliflower rice if you are going to freeze it and stir it in when you reheat it.
  • Reheating: Simmer over medium-high heat in a small saucepan, stirring often to reheat the soup.

Keto Soup Recipe FAQs

What is Keto?

Keto is short for ketogenic which is a low-carb, high-fat diet. It causes the body to go into a metabolic state called ketosis, which burns fat for energy instead of carbohydrates from food. Weight loss is one of the most popular benefits, but there are studies that show if may also help with diabetes, cancer, epilepsy and Alzheimer’s.

If you’re interested in learning more about if it is right for you, to get started or what resources to seek out, this episode featuring two registered dietitians on This Unmillennial Life is a good one to check out. I think this post about the keto diet is really helpful for beginners.

Can I eat soup on a Keto diet?

Yes! Soups are a great option while following a low carb diet or keto diet. Broth, lean protein, nutrient rich vegetables, and flavorful seasonings will keep you satiated and nourished without feeling restricted.

Keto Soup Recipes Cookbook

Carolyn’s cookbook is perfect if you are just starting to think about Keto and low-carb or have been following a Keto diet for a while. She starts out with lists of kitchen tools and pantry items you’ll need. Luckily her keto soups and stews are accessible, so you probably have everything needed to dive right in.

There’s a great section on special Keto substitutions which is really helpful. Like swapping sliced cabbage for noodles, cauliflower rice for rice and turnips for potatoes. Make sure to check it out and here’s a link on amazon.

I especially love Chapter 1: All About Broth. Carolyn does an amazing job describing the difference between bone broth, regular broth and stock and provides recipes to make your own, which I highly recommend when making soup.

I was really excited to try this Keto Chicken Soup. I’ve used cauliflower rice as a side and an addition to salads, but I’ve never tried it in soup. It was awesome. It added just the right amount of flavor and texture, so you truly don’t miss the rice.

This keto chicken soup recipe is ready in just over 30 minutes. I love the gorgeous orangish-red color and subtle flavor the paprika adds and the chunks of tender chicken are perfect. Let’s just say, this keto soup is surprisingly flavorful! All that and it comes in at less than 5 grams net carbs per serving! 🥳

This Keto Chicken Soup with cauliflower rice is ultra-comforting, delicious and ready in less than 40 minutes. It’s low-carb, kid-friendly, paleo-friendly, dairy free, grain free and gluten free, too!

Ingredients

Units Scale
  • 2 tablespoons avocado oil
  • 2 stalks celery, chopped
  • 1/4 cup chopped onions
  • salt and pepper, to taste
  • 2 cloves garlic, minced
  • 1/2 teaspoon dried thyme leaves
  • 1/2 teaspoon paprika
  • 4 cups chicken broth
  • 1 pound boneless, skinless chicken thighs, cubed
  • 8 ounces riced cauliflower (about 2 cups)

Instructions

Notes

Freezing Instructions
