The Ultimate Keto Vegetable Soup
Description
This soup begins with sautéing diced onions, carrots, leek, celery, garlic, zucchini, and herbs like thyme and parsley in butter or olive oil, which builds deep flavor. Cauliflower florets and broth are added with bay leaves and seasoning, then simmered until tender. Half the soup is removed and pureed to thicken the base, then returned to the pot along with kale to soften briefly.
The result is a well-seasoned and textured soup combining creamy and chunky elements, highlighting the natural flavors of the vegetables. A swirl of olive oil and lemon juice just before serving brightens the taste and adds a fresh finish. With just 6 net carbs per portion, it fits well into a keto diet and makes a wholesome meal option.
The soup can be refrigerated for up to 4 days or frozen for 3 months, making it convenient for meal prep. Using vegetable broth and olive oil instead of chicken broth and butter makes the dish suitable for vegetarians and vegans. Adjust seasoning before serving to personal taste.

Add the garlic, zucchini, green beans, chopped thyme and about ⅔ of the parsley. Sauté for another 3 minutes.

- To serve: Mix a squeeze of lemon juice with 1 tablespoon olive oil and swirl into the soup. Top with 1 tablespoon fresh parsley. Adjust seasoning to taste and enjoy.
