One cold winter afternoon, I whipped up this leek and parsnip soup when my backyard plants gave me tons of parsley. The parsnips' sugary goodness and mild leeks combine into something truly wonderful, while all that parsley transforms the soup into a gorgeous green shade. It's now my favorite when I'm craving something that's both warm and bright.

Why You'll Love This

Magic happens as parsnips simmer down - they get super sweet and velvety. The leeks bring their subtle sweetness, and the fresh parsley adds a zingy brightness that livens up your palate. It's just right for those times when you want a warm, comforting bowl that won't leave you feeling heavy.

Grab These Ingredients

  • The Main Players: Peeled and diced parsnips, two thoroughly washed leeks, and a large handful of vibrant parsley.
  • The Foundation: Broth of your preference and some garlic for depth.
  • For Creaminess: Quality olive oil or butter and a splash of cream if you're feeling fancy.
  • For Flavor: Sea salt, cracked pepper, and perhaps a dash of nutmeg for extra warmth.

Cooking Steps

Prep Your Leeks
Remove the dark green parts, split them lengthwise, wash out all the dirt hiding between layers, then slice into circles.
Create The Foundation
Heat your oil in a large pot, gently cook the leeks and garlic until they're soft and fragrant.
Simmer Everything
Toss in your parsnip chunks, add broth, and let it all cook until the parsnips get soft, roughly 20 minutes.
Mix In The Herbs
Throw in your parsley, let it soften briefly, then puree everything until it's silky smooth.

Tips For Success

Make sure you wash those leeks thoroughly - sandy soup is no fun. Don't rush the parsnips - they need to get completely soft for the creamiest texture. If you've got a standard blender, work with small amounts at a time since hot liquid can splash out unexpectedly.

Presentation Ideas

Finish with a swirl of good olive oil to make it look amazing. Some warm bread nearby for dipping is always a good call. I sometimes add a spoonful of sour cream or pair it with a simple salad to turn it into a proper dinner.

Storage Tips

Leftover soup keeps in your fridge for about 3 days. You can stick portions in the freezer for up to 3 months, perfect for those evenings when you just can't be bothered to cook. Warm it up slowly when you're ready to eat it again to keep all those lovely flavors intact.

Tasty Variations

Throw in a couple potatoes if you want something more filling. I'll sometimes mix in grated parmesan at the finish line for extra richness. You can swap the parsley for spinach or kale when you need a change - each green brings different flavors to the party.

Make It Your Own

Adjust the seasonings until they taste just right for you - maybe more black pepper or an extra hint of nutmeg. Sometimes I go all out with loads of cream, other times I keep it lighter. That's the fun part of cooking - tweaking each dish to match exactly what you're craving.

Frequently Asked Questions

→ What should I look for in parsnips?
Opt for smaller, firm, pale ones. Large ones often have woody cores you'll need to cut out. Skip any that feel soft or look blemished.
→ Can I prep this soup ahead of time?
Absolutely. Store it in the fridge for 2–3 days. If it thickens, just stir in a little extra stock while warming it up.
→ What’s the best way to clean leeks?
Slice them lengthwise, rinse under running water, and separate the layers to get rid of dirt. Then chop them into small pieces.
→ Is this soup freezer-friendly?
Totally! It freezes up to 3 months. Let it thaw overnight in the fridge, then warm it slowly. Add fresh herbs once heated.
→ What pairs well with this soup?
Thick, crusty bread is ideal. A light salad or half a sandwich works too. Add some crunch with croutons or toasted nuts.

Ingredients

01 2 cups fresh parsley, chopped finely.
02 2 tablespoons unsalted butter.
03 3 leeks (white to light green parts), cut into thin pieces.
04 2 pounds of parsnips, peeled and diced.
05 2 tablespoons olive oil, with extra for topping.
06 2 teaspoons of kosher salt.
07 4 cups of vegetable or chicken stock.
08 2 cups of water.
09 2 strips of lemon zest, about 1x2 inches each.
10 1 tablespoon of lemon juice.

Instructions

Step 01

In a pot on medium heat, melt the butter. Toss in the leeks, cover, and let them cook on low until they're soft but still pale.

Step 02

Throw in the parsnips, olive oil, salt, stock, lemon peel, and water. Turn up the heat until it boils, then lower it to a simmer. Cover and cook for about 30 minutes, or until parsnips are very soft.

Step 03

Take out the lemon zest. Toss in the parsley, then blend the soup until creamy using an immersion or regular blender.

Step 04

Stir the lemon juice in. Taste and tweak the salt if needed. Sprinkle on black pepper, drizzle a little more oil, and garnish with herbs if you’d like.

Notes

  1. Cut out hard centers from oversized parsnips.
  2. Rinse leeks thoroughly, they often hide dirt.
  3. Go vegetarian by choosing vegetable broth.
