There’s something magical about a bowl of Leek & Potato Soup on a chilly evening—it’s like a warm hug from the inside out. I first fell in love with this dish during a rainy weekend at my aunt’s farmhouse. She served it with thick slices of sourdough, and I swear, it fixed everything that was wrong with that gloomy day. What I adore most about this soup is how simple yet soul-satisfying it is. With just a handful of humble ingredients—leeks, potatoes, a bit of cream—you can whip up pure comfort in under an hour. It’s the kind of recipe that feels fancy but couldn’t be easier, and it adapts beautifully whether you’re cooking for one or feeding a crowd.

Why You’ll Love This Leek & Potato Soup

Oh, where do I even start with why this soup is a total winner in my book? First off, it’s the creamiest, dreamiest bowl of comfort you’ll ever make—no fancy techniques required. Here’s why you’ll be making it on repeat:

Creamy magic: That velvety texture (thanks to blended potatoes and a splash of cream) feels indulgent but isn’t overly heavy.
Weeknight hero: From chop to slurp in under an hour? Yes, please. It’s my go-to when I’m short on time but craving something cozy.
Wallet-friendly: Leeks and potatoes are affordable year-round, and the recipe stretches beautifully for leftovers.
Vegetarian delight: It’s naturally meat-free but so satisfying that even carnivores won’t miss a thing.
Meal prep superstar: Tastes even better the next day, and freezes like a champ (just hold the cream if freezing).

Trust me—once you try it, this soup will earn a permanent spot in your rotation.

Ingredients for Leek & Potato Soup

Gather these simple ingredients—I promise you probably have most already! The magic here is in how ordinary items transform into something extraordinary. Just make sure your leeks are fresh and your potatoes are starchy (Russets or Yukon Golds work best). Here’s what you’ll need:

2 large leeks (white and light green parts only), cleaned well and thinly sliced (those layers hide grit like nobody’s business!)
4 medium potatoes, peeled and diced into 1-inch chunks (about 2 lbs—size matters for even cooking)
1 yellow onion, chopped (no need for perfect dice here—rustic is good)
2 garlic cloves, minced (or 1 tbsp from the jar when you’re in a pinch)
4 cups vegetable broth (chicken broth works too if that’s what’s in your pantry)
1 cup heavy cream (or whole milk for a lighter version—just add it at the end so it doesn’t curdle)
2 tbsp butter (or olive oil if you prefer)
Salt and pepper to taste (start with 1 tsp salt—you can always add more after blending)

See? Nothing fussy—just good, honest ingredients ready to work their magic.

Equipment Needed for Leek & Potato Soup

You won’t need any fancy gadgets for this soup—just a few kitchen staples! Grab these:

A large pot (at least 4 quarts—this soup likes to bubble away happily)
Immersion blender (my absolute favorite for easy blending right in the pot) or a regular blender (just work in batches and be careful with hot liquid!)
Wooden spoon for stirring (a silicone spatula works too—anything that won’t scratch your pot)
Measuring cups (though I often eyeball the cream—no judgment here)

That’s it! Now let’s get cooking.

How to Make Leek & Potato Soup

Alright, let’s get down to business! Making this soup is as easy as 1-2-3—just follow these simple steps, and you’ll have a pot of creamy goodness ready before you know it.

Step 1: Sauté the Aromatics

First, melt that butter in your pot over medium heat (don’t crank it too high—we’re not making toast here!). Toss in your cleaned leeks, onion, and garlic with a pinch of salt. Stir them around until they’re soft and smell amazing—about 5 minutes. Pro tip: If they start browning, lower the heat. We want them sweet and translucent, not crispy!

Step 2: Cook the Potatoes

Now, add your diced potatoes and pour in the broth. Bring everything to a gentle boil, then reduce to a simmer. Let it bubble away uncovered for about 20 minutes—you’ll know it’s ready when the potatoes practically fall apart if you poke them with a fork. (No rushing this step—patient cooking equals velvety soup!)

Step 3: Blend and Finish

Time for the magic! If you’ve got an immersion blender, go to town right in the pot (careful of splatters—I speak from messy experience). Otherwise, blend in batches in your regular blender—just crack the lid slightly to let steam escape. Once smooth, stir in the cream gently, taste, and season with salt and pepper until it’s just right. Boom—soup’s on!

Tips for Perfect Leek & Potato Soup

After making this soup more times than I can count, I’ve picked up a few tricks that take it from good to “oh wow!” Here are my must-know tips:

Clean those leeks like your soup depends on it (because it does!). Slice them first, then soak in a bowl of cold water—the grit will sink to the bottom. I usually give them 2-3 dunks to be safe.
Cream control is key. Want it richer? Add an extra splash of cream at the end. Lighter? Swap in half-and-half or whole milk—just warm it slightly first so it blends smoothly.
Blend smart: For ultra-silky texture, strain through a sieve after blending. Prefer some texture? Pulse briefly or mash with a potato masher instead.
Fresh herbs make it fancy: A sprinkle of chives or thyme leaves right before serving adds color and freshness. Crispy fried shallots are my secret indulgence topping.
Salt in stages: Season lightly at the start, then adjust after blending—potatoes absorb salt differently once pureed.

Follow these, and you’ll have soup that’ll make you feel like a kitchen rockstar!

Variations for Leek & Potato Soup

One of the best things about this soup? It’s a blank canvas for creativity! Here are my favorite ways to mix it up:

Bacon boost: Fry up some chopped bacon before sautéing the leeks—use the drippings instead of butter for extra smoky depth.
Cheesy delight: Stir in a handful of sharp cheddar or Gruyère after blending (trust me, it’s life-changing).
Spice it up: Add a pinch of cayenne or smoked paprika with the garlic for a subtle kick.
Vegan magic: Swap butter for olive oil, use coconut milk instead of cream, and top with crispy roasted chickpeas.
Herb garden: Toss in a bay leaf while simmering, or finish with fresh dill or parsley.

Don’t be afraid to play around—this soup loves a good remix!

Serving and Storing Leek & Potato Soup

This soup practically begs to be served with a hunk of crusty bread—I’m partial to a toasted baguette for that perfect butter-soaking crunch. For chilly nights, I’ll sometimes top bowls with extra sautéed leeks or a drizzle of truffle oil if I’m feeling fancy. Leftovers? Even better the next day! Just store cooled soup in an airtight container in the fridge for 3-4 days. If freezing, skip the cream (add it fresh when reheating). To warm, gently heat on the stove—microwaving can make the texture grainy. Stir in a splash of broth if it thickens too much. Pro tip: Double the batch and freeze half for a future “I don’t feel like cooking” night—your future self will thank you!

Leek & Potato Soup Nutritional Information

Just a heads up—these numbers are estimates (your exact ingredients might change things slightly). Per generous bowl (about 1¼ cups), you’re looking at:

320 calories
18g fat (11g saturated)
35g carbs (with 4g fiber—thanks, potatoes!)
5g protein

Not too shabby for something this creamy and satisfying! The sodium comes in around 450mg, mostly from the broth—use low-sodium if you’re watching that.

Common Questions About Leek & Potato Soup

I get asked about this soup all the time—here are the answers to the most common head-scratchers:

“Can I freeze it?” Absolutely! Just leave out the cream before freezing (add it fresh when reheating). Portion it into freezer bags or containers, and it’ll keep for up to 3 months. Thaw overnight in the fridge before warming gently on the stove.
“How do I make it vegan?” Easy peasy! Swap butter for olive oil, use veggie broth, and replace cream with coconut milk (the full-fat kind gives that luscious texture). Top with crunchy roasted chickpeas for protein.
“Do I have to blend it?” Not at all! For a rustic chunky version, just mash some potatoes with a spoon right in the pot—it’ll be heartier but just as delicious.
“Why is my soup gluey?” Over-blending potatoes can make them gummy. Pulse briefly rather than going full turbo. If it happens, whisk in extra broth to loosen.
