Pure comfort in a bowl! This keto veggie soup is thick and so indulgent that you will reconsider soups overall.
It's a wonderful low carb veggie soup for fall and winter. A real cold weather dream come true!
Made with cauliflower, zucchini, and carrot, it's high in fiber and rich in nutrients. Only 4.7 grams of net carbs in each bowl, it's gluten-free, vegetarian, and easily made vegan.
It’s weeknight-friendly as you can have it on the table in less than 30 minutes, and it keeps well in the freezer if you are into meal prepping.

Ingredients You'll Need
To make my low carb vegetarian soup, you'll only need 7 key ingredients plus some salt and pepper. Easy!
- Vegetables - you'll need fresh zucchini, carrot, and cauliflower for this soup.
- Vegetable oil - to sauté the veggies, I used coconut oil. You can substitute for other vegetable oils such as grapeseed oil, peanut oil, canola oil, or butter.
- Vegetable broth - make sure you check the nutritional information if using store-bought varieties. They often have extra carbs added. You can substitute for chicken or beef broth as well.
- Heavy cream - to make the soup rich and creamy. Substitute coconut cream to make it vegan.
- Garlic - a couple of cloves of minced garlic from a jar.
How To Make It
My low carb veggie soup comes together quickly in one pot. Follow the simple steps below:
- Heat the vegetable oil in a saucepan over medium heat.
- Sauté the zucchini, carrot, and cauliflower for 3 to 5 minutes until tender, seasoning with salt and pepper. Add the garlic and mix everything together.
- Gradually add the cream and vegetable broth. Lower to medium-low heat and continue to simmer for around 10 minutes until the soup has thickened.
- Taste and adjust the seasoning, transfer to bowls and serve hot. Enjoy!
Tips and Variations
Make it vegan keto soup by substituting the heavy cream for coconut cream. The soup will taste just as delicious!
Make it keto vegetable beef soup by using beef stock and adding pieces of cut beef steak.
Make it low carb chicken vegetable soup by using chicken stock and adding cooked chicken.
Storage Instructions
You can keep leftover keto vegetarian soup in the fridge or freezer. Multiply the ingredients to make a large batch and freeze!
- In the fridge: Store leftover soup in an airtight container in the refrigerator. It will keep for up to 1 week in the fridge.
- In the freezer: Make a big batch of my low carb vegetable soup for meal prepping! Let it cool to room temperature, and then pour the soup into freezer-safe bags or containers. Freeze them, and they'll keep for up to 6 months! When ready to eat, let the soup thaw in the fridge overnight.
- To reheat: Place the soup in a microwave-safe bowl and microwave for 30-second intervals until hot. Alternatively, warm it up on the stovetop in a pot.

This literally IS the best soup I’ve ever made. I added chicken because my husband, who isn’t on KETO but is diabetic, needs his meat. I always have to add some carbs for his dietary needs too, so he got crackers. He also went back for seconds. He is not a foodie and rarely describes anything I cook as “delicious”, but this soup is the exception. He told me to put this one in our meal planning on a regular basis. Next time I think I’ll just make the soup with the veggies and give him a meaty sandwich on the side. 5-stars for this delicious, easy to make, homemade soup! YUM!
