Ingredients for Easy Velvety Potato and Leek Soup
Main Soup Base
- Leeks — 4, cleaned and chopped
- Potatoes — 2, peeled and sliced
- Fresh onions — 3, chopped
- Yellow onion — 1, diced
- Garlic — 2 cloves, minced
- Olive oil — 5 tbsp
- Coconut milk — 200 ml (canned or carton)
- Water — about 700 ml (or substitute vegetable broth)
- Salt — 1 tbsp
- Pepper — a pinch
- Dried basil — 1 tsp
- Vegetable stock cube — 1
- Lime — ½, juiced
Optional Garnishes
- Fresh thyme sprigs
- A drizzle of olive oil
Ingredient Notes & Substitutions
- Leeks: Choose leeks with firm white stalks and vibrant green tops. Be sure to rinse well—grit often hides between the layers. If needed, substitute with a mix of shallots and mild onions.
- Potatoes: Starchy potatoes like Russet or Yukon Gold blend into a smooth, creamy texture. Waxy potatoes will work too but create a slightly thinner soup.
- Coconut milk: This keeps the soup naturally dairy-free. For a different flavor profile, you can use oat milk, almond milk, or a splash of regular milk.
- Vegetable stock cube: If you prefer, replace the cube and water with 700 ml of homemade or store-bought vegetable broth for deeper flavor.
- Lime juice: Adds freshness and balances the richness of the coconut milk. Lemon juice can be used as an alternative.
- Oil choice: Olive oil brings a warm, round flavor, but avocado oil or vegetable oil also work if needed.
Step-by-Step Instructions
Step 1 – Prepare the Vegetables
Wash the leeks thoroughly, slice them into thin rounds, and chop the potatoes, onions, and garlic. Preparing everything ahead of time helps the cooking process move smoothly.
Step 2 – Sauté the Aromatics
Heat the olive oil in a large pot over medium heat. Add the leeks, potatoes, and both types of onions. Sauté for about 2–3 minutes until the vegetables begin to soften. Add the garlic and cook for one additional minute, stirring frequently to prevent burning.
Step 3 – Add Liquid and Seasonings
Pour in the coconut milk and add dried basil, salt, pepper, the vegetable stock cube, and the water or broth. Stir well to combine, ensuring the seasonings dissolve evenly.
Step 4 – Simmer the Soup
Lower the heat to medium and let the soup simmer gently for around 15 minutes. The potatoes should be fork-tender, and the leeks soft and fragrant.
Step 5 – Blend Until Velvety Smooth
Remove the pot from the heat and add the lime juice. Use an immersion blender to process the soup until smooth and silky. A traditional blender will work too—just blend in batches and be cautious with hot liquids.
Step 6 – Serve and Garnish
Pour the soup into bowls and finish with a drizzle of olive oil or a sprinkle of fresh thyme for a restaurant-worthy presentation.
Pro Tips for Success

- Blend thoroughly for a true velvety texture.
- Adjust thickness by adding more broth or water after blending.

Flavor Variations
- Herby Potato Leek Soup: Add parsley, thyme, or rosemary while simmering.

- Extra Creamy Version: Stir in additional coconut milk or a spoonful of dairy-free cream.
- Carrot & Potato Blend: Add sliced carrots for a naturally sweet and colorful soup.
