Creamy Vegan Potato Leek Soup Recipe
Ingredients
- 4 medium potatoes, peeled and diced
- 2 leeks, cleaned and sliced (white and light green parts only)
- 1 medium onion, chopped
- 2 tablespoons olive oil
- 2 cloves garlic, minced
- 4 cups vegetable broth
- 1 cup unsweetened plant-based milk
- 1 teaspoon salt (adjust to taste)
- ½ teaspoon black pepper
- 1 teaspoon dried thyme
- Chopped fresh parsley, for garnish (optional)
Instructions
Sauté the aromatics
Heat the olive oil in a large pot over medium heat. Add the chopped onion and sliced leeks and sauté for about 5 minutes, until soft and fragrant. Stir in the garlic and cook for another 30–60 seconds.
Simmer the soup
Add the diced potatoes, vegetable broth, thyme, salt, and pepper. Bring to a boil, then reduce the heat and simmer for about 20 minutes, or until the potatoes are fork-tender.
Blend until creamy
Use an immersion blender to blend the soup until smooth. For a chunkier texture, blend only half the soup and leave some potato pieces intact.
Add creaminess
Stir in the plant-based milk and gently warm over low heat. Taste and adjust seasoning as needed.
Serve and enjoy
Ladle into bowls and garnish with fresh parsley if desired. Serve warm with crusty bread or crackers.

How to Boost the Protein in This Soup
This potato leek soup is naturally comforting and satisfying, but if you want to make it more filling or turn it into a meal-level option, boosting the protein is simple and seamless.
Blend in white beans
Add ½–1 cup of cooked white beans (like cannellini or great northern beans) before blending. They make the soup even creamier while adding plant-based protein and fiber without changing the flavor.
Stir in silken tofu
Silken tofu blends beautifully into soups and adds a noticeable protein boost with zero tofu taste. Blend in ½ cup for a richer, more filling bowl.
Use high-protein plant milk
Swap the plant-based milk for soy milk or pea milk, which contain significantly more protein than almond or oat milk.
Serve with a protein-rich side
Pair the soup with:
- High-protein bread or toast
- A chickpea or lentil salad
- Edamame or roasted chickpeas
Optional non-vegan protein boost
If you’re flexible:
- Swirl in Greek yogurt after blending
- Top with shredded chicken or turkey
- Serve alongside eggs or a protein-forward sandwich
Easy High-Protein Version Example
For a simple upgrade that keeps the soup creamy and cozy:
- Blend in ½ cup white beans
- Use soy milk instead of low-protein plant milk
This keeps the soup comforting while making it far more satisfying and filling.
