Overview

Print

This vegan leek and potato soup is a classic with a twist—it’s made in the slow cooker, which means you set it, forget it, and come back to a pot of rich, flavorful soup. It’s creamy without cream, filling without being heavy, and simple enough for beginner cooks.

• Time requirement: About 4–6 hours in the slow cooker (hands-on prep is less than 20 minutes).
• Difficulty level: Easy—great for anyone new to cooking or vegan meals.
• Why it’s special: It’s naturally dairy-free, gluten-free, and plant-based, but still full of flavor and creaminess.

Essential Ingredients

Here’s what you’ll need to make this soup, plus a few helpful substitutions:

• Leeks – The star of the dish. They bring a mild, onion-like flavor. If you can’t find leeks, you can use onions or a mix of onions and green onions.
• Potatoes – Russet or Yukon gold potatoes work best for creaminess. Sweet potatoes can be used for a different twist.
• Garlic – Adds depth and aroma.
• Vegetable broth – The base of the soup. You can use homemade or store-bought. Low-sodium broth is great if you want more control over the salt.
• Olive oil – Used to sauté the leeks before adding them. Coconut oil or avocado oil also work.
• Seasonings – Salt, pepper, thyme, and bay leaf for earthy flavor.
• Coconut milk or cashew cream (optional) – To add extra creaminess, though the potatoes already give the soup a smooth texture.
• Fresh herbs (parsley or chives) – For garnish and freshness.

Substitutions and Variations:

• For a richer flavor: Add a splash of oat milk or almond milk at the end.
• For extra protein: Stir in white beans or lentils.
• For spice lovers: A pinch of cayenne or smoked paprika can give it a warm kick.

Step-by-Step Instructions

1. Prepare the leeks: Slice off the root ends and dark green tops. Cut the leeks in half lengthwise, then rinse thoroughly to remove dirt. Slice into thin half-moons.
2. Sauté (optional but recommended): In a pan, heat olive oil and sauté the leeks and garlic for 5 minutes until softened. This step deepens the flavor, but you can skip it if you’re in a rush.
3. Layer in the slow cooker: Add the leeks, potatoes (peeled and diced), vegetable broth, thyme, bay leaf, salt, and pepper.
4. Cook: Cover and cook on low for 6–7 hours or on high for 3–4 hours until the potatoes are tender.
5. Blend: Remove the bay leaf. Use an immersion blender directly in the slow cooker to puree the soup until creamy. If you like a chunkier texture, blend only half.
6. Finish: Stir in coconut milk or cashew cream if using. Taste and adjust seasoning.

Assembly and Presentation

Once blended, ladle the soup into bowls. For a cozy presentation:

• Drizzle a little olive oil or coconut cream on top.
• Sprinkle with fresh herbs like parsley, dill, or chives.
• Serve with crusty bread or a slice of sourdough for dipping.

Tip: If you’re making this for a dinner party, serve it in small mugs or cups as a starter—it feels elegant and comforting.

Storage and Make-Ahead Tips

One of the best things about this soup is how well it keeps:

• Refrigerator: Store in an airtight container for up to 4 days.
• Freezer: Freeze in portions for up to 3 months. Thaw overnight in the fridge before reheating.
• Reheating: Warm gently on the stovetop or in the microwave, stirring well. If it’s too thick, add a splash of broth or water.

Recipe Variations

• Rustic Style: Don’t blend the soup fully—leave it chunky with soft potato bites.
• Green Boost: Add spinach or kale in the last 10 minutes of cooking for extra nutrients.
• Carrot and Leek Soup: Swap half the potatoes with carrots for a sweeter flavor.
• Curried Version: Add curry powder or turmeric for a golden, spiced soup.

This soup isn’t just tasty—it’s nourishing too:

• Leeks are rich in antioxidants and vitamins A, C, and K.
• Potatoes provide fiber and potassium.
• It’s naturally low in fat but still filling thanks to the creamy texture.
• Vegan and gluten-free, making it suitable for a wide range of diets.
