Ingredients

Main Ingredients

2 tablespoons butter or olive oil
3 large leeks, white and light green parts only, cleaned and sliced
3 cloves garlic, minced
4 large Yukon Gold or Russet potatoes, peeled and diced
4 cups (1 liter) vegetable or chicken broth
1 teaspoon dried thyme (or 1 tablespoon fresh)
1 bay leaf
½ teaspoon salt, plus more to taste
¼ teaspoon freshly ground black pepper
1 cup (240 ml) milk or half-and-half (optional for creaminess)
2 tablespoons chopped fresh parsley or chives (for garnish)

Optional Additions

½ cup shredded cheese for extra richness
¼ teaspoon smoked paprika or nutmeg for depth
1 tablespoon lemon juice for brightness

Equipment

Instant Pot or electric pressure cooker
Immersion blender or countertop blender
Wooden spoon and ladle

Instructions

1. Prepare the Leeks and Potatoes

Start by trimming the leeks — remove the dark green tops and roots, keeping only the white and pale green parts. Slice them into rings, then rinse well under running water to remove any dirt between the layers. Dice the potatoes into 1-inch cubes for even cooking.

2. Sauté the Aromatics

Set the Instant Pot to Sauté mode and melt the butter or warm the olive oil. Add the sliced leeks and cook for 4–5 minutes, stirring occasionally, until they soften and become fragrant. Stir in the garlic and cook for another 30 seconds.

3. Add the Potatoes and Seasonings

Add the diced potatoes, thyme, bay leaf, salt, and pepper. Stir well to coat the vegetables in the buttery leeks and herbs. Pour in the broth, scraping the bottom of the pot to release any caramelized bits — this adds depth to the flavor and prevents burning.

4. Pressure Cook

Cancel Sauté mode, secure the lid, and set the Instant Pot to Pressure Cook (High) for 10 minutes. Once the timer goes off, allow a 10-minute natural release, then carefully quick-release any remaining pressure. Remove the bay leaf.

5. Blend the Soup

Use an immersion blender to puree the soup until smooth and creamy. For a slightly chunky texture, pulse a few times rather than blending completely. If you prefer to use a countertop blender, work in small batches and be careful with the hot liquid.

6. Add Creaminess (Optional)

If you’d like a richer soup, stir in the milk or half-and-half and switch to Sauté mode for 2–3 minutes to gently warm through. Do not boil after adding dairy — just heat until steamy. Taste and adjust seasoning with extra salt, pepper, or a splash of lemon juice for brightness.

7. Serve and Garnish

Ladle the soup into bowls and garnish with chopped parsley or chives. Add a swirl of cream, a sprinkle of shredded cheese, or freshly cracked pepper for an elegant finishing touch.

Tips for Success

Clean leeks thoroughly: Dirt hides between layers, so rinse well.
Choose the right potatoes: Yukon Golds give a creamy, buttery texture; Russets create a fluffier consistency.
Avoid over-salting early: The flavors deepen after pressure cooking, so adjust at the end.
Control thickness: Add more broth if it’s too thick, or let it simmer uncovered to reduce.
For extra flavor: Stir in roasted garlic or caramelized onions before blending.

Flavor Variations

Vegan Version: Use olive oil and plant-based milk for a dairy-free, creamy finish.
Herb Lovers: Add rosemary or tarragon for an aromatic twist.
Spicy Kick: Add a pinch of cayenne or crushed red pepper flakes.
Loaded Potato Style: Top with shredded cheese, green onions, and a dollop of yogurt.
Autumn Touch: Stir in roasted parsnips or a handful of spinach for extra nutrients.

Serving Suggestions

Serve with toasted baguette slices, garlic bread, or crackers.
Pair with a simple salad dressed in lemon vinaigrette for contrast.
Drizzle with truffle oil or sprinkle with crispy shallots for a gourmet touch.
Enjoy as a starter course or light main dish with roasted vegetables.

Storage & Reheating

Refrigerate: Store in an airtight container for up to 4 days.
Freeze: Allow soup to cool completely, then freeze for up to 3 months. Thaw overnight in the fridge before reheating.
Reheat: Warm on the stove over medium heat or in the Instant Pot on Sauté mode, stirring occasionally. Add a little broth or milk if it thickens too much.
