Is Vegetable Soup Keto-Friendly?

Classic vegetables usually may contain noodles, potatoes, peas, and other high-carb ingredients. But, if you use low carb ingredients and replace noodles, potatoes with turnips, cauliflower, or radishes, a vegetable soup is perfect for enjoying on a ketogenic diet.

It’s easy to meal prep this vegetable soup. I buy seasonal products, chop them and store them in individual bags in the freezer, and when I’m craving a soup, I just add the veggie to a large pot. Here’s a list of my favorite vegetables for soup: 

  • cabbage
  • broccoli
  • carrots
  • cauliflower
  • celery
  • kale or spinach
  • red or yellow peppers
  • onion
  • green beans 
  • squash
  • mushrooms

Ingredients For Keto Vegetable Soup

You will be surprised when you find out that you will make an incredibly delicious Low Carb Vegetable Soup that will impress everyone with some simple ingredients.

  • Olive Oil -You can easily replace it with butter or avocado oil.
  • Onion & Garlic -These are two essential components that give this vegetable soup recipe a unique flavor.
  • Vegetables – I used onion, carrots, zucchini, bell pepper, celery, cauliflower florets to replace potatoes, green beans instead of peas, and canned tomatoes.
  • Low Sodium Broth: Use chicken stock, beef stock, vegetable broth for a vegan vegetable soup. For some extra health benefits, you can even replace it with Bone Broth. 
  • Seasonings: Season this soup to taste with salt, pepper, crushed red pepper flakes, Italian seasoning.

How To Make Keto Vegetable Soup

To make this delicious homemade vegetable soup, just follow a few simple steps and prepare your knife; there’s lots of chopping included. 

  1. Prepare all the vegetables by peeling and dicing them into small pieces.
  2.  Start by sauteing some onion and red peppers for a couple of minutes until the onions begin to change color and become tender.
  3. Then add the garlic and cook for about 30 seconds until fragrant.
  4. After that, you can add the rest of the vegetables, broth, and seasonings. 
  5. When the soup starts to boil, reduce to medium heat and cook for 15-20 minutes, covered, or until the vegetables are tender.
  6. Taste and adjust the seasonings if necessary.

Tip: If you’re not a fan of chunky vegetable soup, take a few cups of soup out, puree using a hand mixer, and return it to the pot.

Carbs In Vegetable Soup

Carbs in this keto soup come mostly from vegetables which also have fiber. To reduce carbs even more, you can use less onion or carrots.

This keto vegetable soup contains only 8 grams of net carbohydrates per serving. Also, all of the carbohydrates come from vegetables, which is usually a wholesome thing. In my opinion, it’s the best veggie soup recipe that you will ever try.

How To Store Low Carb Vegetable Soup?

This delicious low carb vegetable soup can be stored in the fridge for up to 4 days.

Another excellent option for storing vegetable soup is freezing. Once the soup has cooled to room temperature, transfer it to freezer containers and keep it for up to 3 months. To show this low carb vegetable soup, place the bag in the fridge overnight. Use a container or a shallow bowl in case it leaks. The next day, heat up on the stove or in the microwave.

What Seasonings Are Best for Vegetable Soup?

Vegetable soup is super customizable and can season it with any of your favorite seasonings such as:

  • Italian herb mix
  • basil
  • rosemary
  • chili flakes
  • cumin
  • hot sauce
  • smoked paprika

Regarding the seasonings that I used for this Vegetable Soup, I recommended: garlic, celery, parsley, and Italian seasoning.

How to Serve Keto Vegetable Soup

If you don’t like to eat it simply as it is, here are some suggestions to make this Low Carb Vegetable Soup more enjoyable:

  • Eat it with Cornbread – this keto cornbread is fluffy, and tender, and it’s perfect for dipping into this delicious vegetable soup.
  • Something crispy and spicy like these Keto Cheese Chips also pairs great with vegetable soup on a low carb diet.
  • Seeds Crackers 

Substitutions

If you don’t care about carbs, feel free to use potatoes, peas, butternut squash, and corn.

On the other hand, if you are looking for a strict keto recipe, don’t add carrots and onion. If you don’t have all the vegetables on hand, it’s not a big deal as you can use any vegetables you have in your pantry. The result is still delicious. 

You can also use spinach, kale, broccoli, turnips, mushrooms, green peppers, eggplants, and pumpkin to substitute for the missing ingredients.
