Dairy-Free Whole30 Potato and Leek Soup

I love a hearty soup, and this Whole30 Potato Leek Soup is one of my favorites. Loosely inspired by the classic French vichyssoise, it’s rustic, comforting, and easy enough for weeknight dinners. With just a few simple ingredients and one pot, the result is a silky, flavorful soup that pairs beautifully with crusty bread or a crisp side salad.

This recipe starts by gently sautéing leeks, onion, and garlic in olive oil until they soften and develop a touch of caramelization. Adding russet potatoes and low-sodium chicken broth and simmering until the potatoes are fork-tender gives you the perfect base to blend into a creamy, velvety soup. For a dairy-free version that stays Whole30-friendly, a neutral dairy-free creamer is stirred in at the end for extra creaminess.

Serve the soup as-is for a simple, elegant bowl, or dress it up with toppings like crisp bacon bits and chopped chives for a baked potato–style finish. This recipe yields about six servings and reheats well for lunches or light dinners (see freezing notes in the FAQ).

Ingredients

• 2 tablespoons extra virgin olive oil
• 1 cup diced yellow onion (about 1/2 medium)
• 4 garlic cloves, minced
• 2 cups thinly sliced leeks (white and light green parts only; about 2 large leeks)
• 2 teaspoons kosher salt, plus more to taste
• 3 pounds russet potatoes, peeled and cut into 1-inch pieces (about 4 potatoes)
• 6 cups low-sodium chicken broth
• 2 bay leaves
• 1 teaspoon finely chopped fresh thyme
• 1/8 teaspoon cayenne pepper (optional)
• 1 cup Nutpods Original dairy-free creamer (or substitute half-and-half/heavy cream if not dairy-free)

Step-by-step

Step One: Sauté the onions, garlic, and leeks

Heat the olive oil in a large pot or Dutch oven over medium heat. Add the diced onion, minced garlic, sliced leeks, salt, and pepper. Cook, stirring occasionally, until the leeks and onions are soft and just beginning to caramelize, about 6 to 8 minutes.

Step Two: Add the potatoes

Add the peeled, diced potatoes to the pot along with the chicken broth, bay leaves, chopped thyme, and cayenne (if using). Stir to combine and bring the mixture to a boil over medium-high heat.

Step Three: Simmer until tender

When the liquid reaches a boil, reduce the heat to maintain a gentle simmer. Cover and cook until the potatoes are very fork-tender, about 15 minutes. Check a few pieces to ensure softness before blending.

Step Four: Blend the soup

Remove and discard the bay leaves. Use an immersion blender to puree the soup in the pot until smooth and creamy. If you don’t have an immersion blender, carefully transfer the soup in batches to a countertop blender, blend until smooth, and return it to the pot.

Step Five: Finish with creamer and serve

Stir in the dairy-free creamer (or your chosen cream substitute) until fully incorporated. Taste and adjust seasoning with additional salt or pepper if needed. Ladle into bowls and serve hot. Optional toppings: chopped chives, crisped bacon, or a drizzle of extra-virgin olive oil.
