Potato, Leek and Chorizo Soup

The smell hit me before I even walked into the kitchen. My neighbor was cooking something smoky and rich, and when I asked, she just smiled and said, "chorizo and leeks." I'd never thought to put them together before, but that afternoon changed how I thought about soup. It wasn't fancy or complicated, just honest ingredients doing what they do best. I went home and made my own version that same night, and it's been in my rotation ever since.

I made this for my brother once when he showed up unannounced on a freezing Tuesday. He sat at the counter, quiet and cold, and I didn't ask questions. I just started chopping leeks and frying chorizo, and by the time I ladled the soup into a bowl, he was already warming up. We didn't talk much that night, but he texted me two days later asking for the recipe. Sometimes food says more than words can.

Ingredients

• Leeks: Use only the white and light green parts, they're tender and sweet, while the dark green tops can be tough and bitter.
• Potatoes: Any starchy variety works well here, they break down just enough to thicken the broth naturally without needing flour or cornstarch.
• Chorizo sausage: The smoky, slightly spicy Spanish kind is what you want, it releases vibrant red oil that flavors the entire pot.
• Chicken or vegetable stock: Homemade is lovely, but a good quality store-bought version works just as well, just taste before adding extra salt.
• Heavy cream: This is optional but it adds a silky richness that makes the soup feel a little more special on hard days.
• Smoked paprika: Just half a teaspoon deepens the smokiness from the chorizo and ties everything together beautifully.
• Bay leaf: Don't skip this, it adds a subtle herbal backbone that you'd miss if it wasn't there.
• Olive oil: Used to start the base, it helps render the chorizo fat and keeps everything from sticking.

Instructions

Render the chorizo:

Heat olive oil in a large pot over medium heat, then add the chorizo and fry for 3 to 4 minutes, stirring occasionally. The oil will turn a gorgeous red and the edges of the chorizo will crisp up, remove half and set it aside for later.

Soften the aromatics:

Toss in the onion, leeks, and garlic, stirring them into that flavored oil. Let them cook gently for 5 to 7 minutes until they're soft, fragrant, and just starting to stick to the bottom of the pot.

Build the base:

Add the diced potatoes, smoked paprika, and bay leaf, stirring everything together for about 2 minutes. This toasts the paprika slightly and coats the potatoes in all that smoky goodness.

Simmer until tender:

Pour in the stock, bring it to a boil, then lower the heat and let it simmer uncovered for 20 minutes. The potatoes should be completely tender and starting to break down at the edges.

Adjust the texture:

Remove the bay leaf, then decide if you want it chunky or creamy. For a smoother soup, use an immersion blender and pulse a few times, leaving some texture if you like.

Finish and season:

Stir in the cream if using, taste, then season with salt and pepper. Let it simmer for 2 more minutes so everything melds together.

Serve:

Ladle the soup into bowls and top with the reserved crispy chorizo and a sprinkle of fresh parsley. Serve it hot with crusty bread on the side for dipping.

Save

There was a night last winter when the power went out and I made this soup on the gas stove by candlelight. It felt like something out of an old cookbook, quiet and simple and exactly what we needed. My daughter sat at the table doing homework by flashlight, and when I set the bowl in front of her, she looked up and said it smelled like safety. I think about that a lot now when I make it.

How to Store and Reheat

This soup keeps beautifully in the fridge for up to four days in an airtight container. The flavors actually deepen overnight, so leftovers are a gift to your future self. Reheat gently on the stovetop over low heat, stirring occasionally, and add a splash of stock or water if it's thickened too much. If you froze it, let it thaw in the fridge overnight before reheating, the cream may separate slightly but a good stir brings it back together.

Swaps and Substitutions

If you can't find chorizo, smoked sausage or even diced bacon will give you that savory, smoky backbone. For a vegetarian version, skip the meat entirely and add smoked paprika and a teaspoon of liquid smoke to the oil before cooking the leeks. You can swap heavy cream for coconut cream if you're avoiding dairy, it adds a different kind of richness but it works. If potatoes aren't your thing, try using diced sweet potatoes or even white beans for body and texture.

What to Serve Alongside

This soup is hearty enough to stand alone, but it loves a thick slice of crusty bread, toasted and rubbed with garlic if you're feeling fancy. A simple green salad with a sharp vinaigrette balances the richness beautifully. On colder nights, I'll set out a board with cheese, olives, and pickles so people can graze while the soup simmers.

• Garlic bread or sourdough toast
• A crisp arugula salad with lemon dressing
• Manchego cheese and marcona almonds on the side

This soup has become my cold weather default, the thing I make when I need something comforting without thinking too hard. It's forgiving, flexible, and always tastes like home, no matter whose home that is.

Recipe FAQ

→ Can I make this soup ahead of time?

Yes, this soup stores beautifully. Prepare up to 3 days ahead and refrigerate in an airtight container. The flavors deepen over time. Reheat gently on the stovetop, adding a splash of stock if needed to adjust consistency.

→ What type of chorizo works best?

Spanish chorizo works perfectly for this soup as it's cured and adds smoky, paprika-rich flavor. Avoid Mexican-style fresh chorizo, which has a different texture and seasoning profile. Slice or dice the chorizo for even distribution throughout the soup.

→ How can I make this dairy-free?

Simply omit the heavy cream—the soup remains delicious and naturally creamy from the potatoes. For extra richness without dairy, add a tablespoon of olive oil or use coconut cream as an alternative.

→ Can I freeze this soup?

Yes, this soup freezes well for up to 3 months. If using cream, add it fresh when reheating rather than before freezing for best texture. Cool completely, portion into freezer-safe containers, and thaw overnight in the refrigerator before reheating.

→ What potatoes are best for this soup?

Waxy or all-purpose potatoes like Yukon Gold work beautifully, holding their shape while contributing creaminess. Russet potatoes will break down more, creating a thicker, more velvety texture. Choose based on your preferred consistency.

→ How do I properly clean leeks?

Slice the leeks lengthwise, then rinse thoroughly under cold water, separating the layers to remove trapped dirt and sand. Pat dry before slicing. Use only the white and light green parts for the best flavor and texture.
