Potato Leek Creamy Soup

Featured in: One-Pot Comforts

This velvety potato and leek soup delivers French-inspired comfort in just 50 minutes. The combination of Yukon Gold potatoes and sweet leeks creates a naturally creamy texture that's incredibly satisfying. Sautéed aromatics including onion, garlic, and celery build depth, while fresh thyme and bay leaf add herbaceous complexity. The base version is wonderfully vegetarian and dairy-light, though the soup easily transforms with cream for richness or becomes a seafood chowder with shrimp, scallops, or white fish. Crispy bacon makes an excellent garnish for those who enjoy savory contrast. The result is an elegant yet approachable bowl that works equally well as a standalone meal or sophisticated first course. Simply blend until silky smooth, or leave slightly chunky for rustic texture. Either way, it's pure comfort in a bowl.

Recipe FAQ

Can I make this soup ahead of time?

Absolutely. This soup actually develops deeper flavor when made ahead. Store in the refrigerator for up to 3 days. Reheat gently over medium-low heat, adding a splash of milk or broth if it has thickened. The dairy may separate slightly when reheated, but whisking will bring it back together.

What's the best potato variety for this soup?

Yukon Gold potatoes are ideal because they have naturally creamy flesh and moderate starch content. They break down beautifully during simmering, creating that luxurious velvety texture. Russets work too but may become gluey if over-blended. Red potatoes hold their shape better if you prefer chunky soup.

How do I clean leeks properly?

Leeks often hide sand between their layers. Slice them first, then place in a bowl of cold water. Swish vigorously with your hands—the dirt will sink to the bottom. Lift the leeks out carefully, leaving the sediment behind. Repeat if the water remains cloudy. Pat dry before cooking.

Can I freeze this soup?

The base soup without milk or cream freezes well for up to 3 months. Dairy can sometimes separate when frozen and reheated, so add the milk after thawing and reheating. If you've already added dairy, the soup is still edible but may have a slightly grainy texture—simply whisk or blend to smooth it out.

What can I serve with this soup?

Crusty bread is classic for soaking up every drop. A crisp white wine like Sauvignon Blanc or Chardonnay complements the creamy texture. For a complete meal, pair with a simple green salad with vinaigrette. If serving as a starter, it pairs beautifully with roasted chicken or fish as the main course.
