Potato Leek Soup (Spiced)

Creamy potatoes, sweet leeks, and a warm hit of cumin and nutmeg. Cozy, classic, and just bold enough to make you go back for “one more spoon.”

Potato leek soup is the sweater weather classic for a reason: it is gentle, filling, and basically impossible not to love. But I like mine with a little extra personality. Think traditional at the core, with a warm spice cabinet whisper in the background. Nothing loud. Just aromatic enough that you pause mid-bite like, “Wait, what is that?”

This version keeps the ingredients easy and the steps low drama. We build flavor by sweating leeks slowly (do not rush this part), bloom a few spices in the butter, then let potatoes do what potatoes do best: turn a humble pot of broth into something velvety and comforting.

Why It Works

  • Cozy, creamy texture without fuss: You can blend it silky smooth or keep it a little rustic.
  • Real leek flavor, not onion soup in disguise: A slow sauté pulls out that sweet, mellow leek magic.
  • Spiced, not spicy: Cumin and a tiny pinch of nutmeg add warmth and aroma, not heat.
  • Weeknight friendly: One pot, simple prep, and leftovers reheat like a dream.

Storage Tips

How to Store and Reheat

  • Fridge: Cool completely, then store in an airtight container for up to 4 days (as a general guideline).
  • Freezer: Freeze up to 3 months for best quality. If you used heavy cream, it can separate a bit after thawing. It is still totally usable, just reblend or whisk well while reheating.
  • Reheat: Warm gently on the stovetop over medium-low, stirring often, until hot throughout. If it thickens a lot (it will), loosen with a splash of broth or water until it is spoonable again.
  • Make-ahead tip: For the smoothest texture, blend before storing, then reheat and add cream at the end.

Common Questions

Common Questions

Do I have to use cream?

Nope. Cream makes it lush, but you can swap in half-and-half, whole milk, or even leave it out entirely. If skipping dairy, blend in a drizzle of olive oil at the end for a surprisingly silky finish. For a non-dairy option, an unsweetened oat or soy “cooking cream” also works nicely.

What is the best potato for potato leek soup?

Yukon Gold is my favorite for a naturally buttery texture. Russets also work and blend super smooth, but they can make the soup a bit thicker and starchier. If using russets, you may want a little extra broth.

How do I clean leeks without losing my mind?

Slice them first, then soak in a big bowl of cold water. Swish, let the grit sink, and lift the leeks out with your hands or a spider. Repeat if the water looks sandy.

Can I make it chunky?

Absolutely. Blend only half the soup, then stir it back in. You get creamy body plus soft potato pieces, which is a great combo.

My soup tastes flat. What should I do?

Add salt first, then a tiny splash of lemon juice or a teaspoon of white wine vinegar. Acid wakes up potato soups like flipping on a light switch.

Can I make it vegetarian?

Yes. Use vegetable broth instead of chicken broth. Everything else stays the same, and it is still deeply cozy.

I used to think potato leek soup was the definition of polite food. Great, sure. But also a little too well-behaved. Then I started treating it like I treat most things in my kitchen: sauté longer than you think, season like you mean it, and taste early and often. The first time I bloomed cumin in the pot before adding the broth, the whole kitchen smelled like something you would gladly come home to after a long day. Now it is my go-to “I need comfort but I still want flavor” soup, and it never asks for perfection. Just a spoon.
