Soups and stews are the perfect comfort food and are one of my favorite recipes to make...especially low carb soups! In this post I give tips on thickening keto soups, vegetables that are best for a low carb or keto diet, plus my 31 soup recipes all in one place. It's really easy to make your favorite soup low carb diet friendly...let me show you how!

Low Carb and Keto Soup Recipes

You may think Low Carb Soup Recipes are hard to develop because we have to leave out all of the "good stuff" that most soups contain. This includes thickeners like flour and corn starch and bulking ingredients like pasta and potatoes.

With a few tweaks and easy to find simple ingredients, you can make almost any delicious soup recipe low carb or keto friendly. So if you see a soup recipe out there that you want to transform into a low carb soup, just hit up this post for all of my tips plus over 30 low carb soup recipes!

The cooking vessel

I try to provide multiple cooking methods in a lot of my soup and stew recipes (like my Keto White Chicken Chili) so you can make it any way you like. All 3 are great options.

• Dutch oven: This is a heavy pot, typically cast iron, with a lid. You could also use a large pot with a lid. You do not need a heavy dutch oven to make soup on the stove top.
• Crock Pot: Some of my best keto soups are slow cooked.
• Instant Pot: This cooking method is great for tough meats like stew meat or pot roast.

The liquid

The liquids in all of my easy keto soup recipes are chicken broth or beef broth (also chicken stock or bone broth). I usually start with at least 4 cups but I sometimes put up to 6 cups. I usually make the broth with a concentrate that you can find in the grocery store in the same section as the broths. This takes up way less pantry space and tastes just as good, if not better!

I always wait until my soup is finished cooking to season with salt because these store bought broths can be quite salty, unless you use low sodium.

Another liquid I frequently add to soups is heavy cream! It's my go-to when I want a creamy soup.

The vegetables

Vegetables are a must in any soup I make. It gives my low-carb soup recipes bulk and makes for a more hearty soup. I usually start off a soup with onion, celery, and carrots sautéed in avocado oil or olive oil. I try to keep the onion and carrots to a minimum because they do have a lot of carbs in large quantities.

Some other vegetables that are perfect in low carb soups are broccoli, cauliflower, shredded cabbage, mushrooms, green beans, any kind of squash, pumpkin puree (a great soup thickener), diced tomatoes, chopped bell peppers, kale, radishes (a great potato replacement), and spinach.

Here are some common starches and their much less starchy vegetable alternative:

• Rice: cauliflower rice or riced broccoli
• Pasta: spaghetti squash (like in my Keto Chicken Soup Recipe), zucchini noodles, shredded cabbage, or butternut squash noodles.
• Potatoes: chopped or pureed celery root, cauliflower florets, radishes, mushrooms.

The herbs and spices

Most of the time I use dried herbs and spices in my soup recipes. These usually include cumin, chili powder, smoked paprika, dried thyme, dried basil, Italian seasoning, garlic powder, bay leaves, and onion powder. And of course, salt and pepper!

Fresh herbs are great in soups as well. Chopped fresh parsley, fresh thyme, rosemary, fresh basil, or cilantro add such an amazing fresh flavor.

Let's not forget acids and aromatics to help kick our keto soups up a notch! Minced garlic and shallot add so much flavor as do lime juice and lemon juice (like in my Lemon Chicken Soup).

The protein

Of course there is always shredded or chopped chicken breasts and boneless skinless chicken thighs which would be the most popular soup additions (Like in my Keto Taco Soup). Ground beef and slow cooked stew meat also make great sources of protein. I always cook the meat first before adding the broth. If you're short on time, the pulled meat from a rotisserie chicken is the perfect way to make a very flavorful and hearty chicken soup!

Crispy chopped bacon is a good addition to low carb soup recipes as well!

The thickeners

My favorite soup thickener is Xanthan gum. It is so easy to use and can be found in most grocery stores. I have found it in Walmart on the baking isle and in my local grocery store down the street. Since we usually only use less than a teaspoon at a time, the package lasts for a while. Typically you only need 1 teaspoon of it to thicken a large pot of soup.

You can also learn more about this ingredient here: what is Xanthan gum?

Some other low-carb thickeners are cream cheese, sour cream, and shredded cheddar cheese...though these are not as effective as Xanthan gum.

To thicken vegetable soups like a creamy cauliflower soup or broccoli soup, you can puree some of the vegetables with an immersion blender or add a canned puree such as pumpkin. This is the perfect way to thicken a vegetable soup. I do this is my Keto French Onion Soup and my Acorn Squash Soup.

Freezing low carb and keto soups

There are a lot of soup recipes that freeze really well, such as broth based soups with hearty vegetables. You can freeze creamy soups, you will just need to make sure you reheat them gently on the stovetop so the cream doesn't split.

You can freeze soup recipes in an airtight container or bag in the freezer for up of 4 months. You'll want to thaw them overnight in the refrigerator before re-heating.
