Make Potato Leek Soup Dairy Free

This dairy free potato leek soup is a fantastic take on the classic without all the dairy. I’m all about making recipes plant-based and dairy free when I can. Dairy-free cooking does NOT have to be bland, boring, or flavorless… It’s quite the opposite when done right. You can achieve total richness and creaminess with some simple swaps. By building meals around vegan pantry staples and swapping in a few plant-based ingredients you can make better meals for you and your family.

I made a list of my 125 favorite vegan pantry ingredients that we use on a weekly basis, and check out all my vegan recipes here that are on The Herbeevore. These easy and quick recipes are fantastic meatless and dairy free meals for your table.

What’s In This Crock Pot Potato Leek Soup Recipe?

See the recipe card below for full ingredient amounts and recipe instructions!

• Leeks, Onion, Garlic, Potatoes

• Extra Virgin Olive Oil: I like to use this fruity olive oil which has a fantastic flavor and deep color- it’s really inexpensive online here, so I keep a few liters stocked up in my pantry.
• Herbs de Provence: my favorite spice blend! This French blend has a mix of rosemary, thyme, sage, and savory for a wonderful and complex flavor.
• Bay Leaves: I always add bay leaves to every bean soup I make… it gives the soup a je ne sais quoi which is savory and delicious! When I lived in California I had laurel bay trees in my backyard, and I used to pick the dried leaves… now I buy these online ?
• Low Sodium Vegetable Stock – I like to use this low sodium vegetable stock for my recipes because it has great flavor… without all the salt. I always use low sodium or no-salt-added broth or stock to start, and then I can add salt or other spices later if needed.
• Salt & Pepper
• Coconut Milk: I use unsweetened full-fat coconut milk, which I’d definitely recommend over lite coconut milk. The flavor makes this dish super rich and creamy without any dairy.

How Do I Make Potato Leek Soup in a Slow Cooker?

1. To your slow cooker, add the: olive oil, onion, garlic, diced potatoes, herbs de Provence, bay leaves, vegetable stock, salt and pepper. Mix well to combine.
2. Set the slow cooker on High for 6 hours, or Low for 8 hours, until the potatoes are cooked all the way through. Add the coconut milk, remove and discard the bay leaves, and stir well.
3. Using a hand blender (or by transferring batches of the soup into a blender) blend until the soup is completely creamy and pureed.
4. Top with extra cracked pepper, and stir in a spoon full of coconut milk into each to garnish.

A Note about Washing Leeks

Leeks grow in loose sandy soil – make sure you wash every layer of your leeks before adding them to the crock pot! The last thing you want is to get sand in your soup. I wash my leeks before and after I chop them to make sure I’m getting all the sand and dirt off.
