Why This Soup is a Keto Superstar
- Low-carb goodness: Broccoli and leeks are naturally low in carbohydrates, making this soup a perfect fit for your keto lifestyle.
- Nutrient powerhouse: Both broccoli and leeks are loaded with vitamins, minerals, and antioxidants.
- Electrolyte boost: This soup is an excellent source of potassium and sodium, essential electrolytes often depleted on a keto diet.
- Creamy texture without the carbs: We use heavy cream to achieve a rich and satisfying texture without compromising your carb count.
Ingredients
- 1 Leek (white part only)
- 1 clove Garlic (roughly chopped)
- 3 ounces Butter (salted)
- 1 pound Broccoli (about two medium heads)
- ½ cup Heavy Cream
- 2 ½ cups Chicken Stock
- 1 teaspoon Salt
- 1 teaspoon Pepper
- 1 tablespoon Parsley (chopped)

How To Make Keto Broccoli & Leek Soup
- Sauté: Melt the butter in a large saucepan over low heat. Add the chopped leek and garlic, and sauté until soft and translucent.
- Add the broccoli: Chop the broccoli into florets and add them to the saucepan. Pour in the chicken stock, ensuring the broccoli is mostly covered.
- Simmer to perfection: Simmer for about 8 minutes or until the broccoli is tender and easily pierced with a fork. Be careful not to overcook, as this can affect the color and flavor of the soup.
- Blend until smooth: Using an immersion blender (stick blender), carefully blend the soup until it’s perfectly creamy and smooth.
- Season and serve: Season with salt and pepper. Add a dash of heavy cream and garnish with chopped parsley.
Tip: Using a stick blender is much safer and easier than a traditional blender when pureeing hot soup.
