I stumbled upon this parsnip soup idea during a cold spell when my backyard plot yielded way too many parsnips. Something truly wonderful happens when you combine those sweet oven-roasted root veggies with soft, buttery leeks. Everyone wants to know how I make it, especially when they notice that gorgeous creamy texture topped with bright green parsley sprigs.
What Makes This So Good
Parsnips bring a natural sweetness that works amazingly with the gentle flavor of leeks, and the fresh parsley adds just the punch it needs. You won't believe how easy it is to make, yet it tastes like you spent hours in the kitchen. It's exactly what you need on cold evenings when you want comfort food, or when guests drop by and you need to wow them without much work.
Grab These Items
- From The Garden: Pick out sturdy parsnips and fat leeks—go for the freshest you can find for maximum sweetness.
- Green Stuff: Get a hefty bunch of parsley—it'll transform both the flavor and look of your soup.
- From Your Pantry: Quality butter, heavy cream, and whatever stock or broth you prefer.
- Flavor Boosters: Some sea salt, black pepper, and maybe a touch of nutmeg if you're feeling adventurous.
Cooking Steps
- Get Veggies Ready
- Wash leeks thoroughly—they're notorious for hiding dirt. Cut parsnips into chunks after peeling, and don't forget to take out any hard cores.
- Create Your Foundation
- Drop butter into your largest pot, then cook those leeks until they're soft and smell amazing.
- Put It All Together
- Throw in parsnips with your stock and let everything bubble away until you can easily stick a fork through the parsnips.
- Blend Until Velvety
- Add your fresh parsley, whiz everything until completely smooth, then pour in cream and mix until it looks just right.
Chef's Notes
Don't skip checking parsnips for those tough middle bits—they'll ruin your silky soup. Watch those leeks carefully; you want them tender, not burnt. Don't even think about using dried parsley here—it just won't cut it. And if you're using a standard blender, don't fill it too full—hot soup can explode up and make a huge mess.
Serving Ideas
This soup practically demands a nice piece of crusty bread for dipping. We love pairing it with fresh-baked Irish soda bread, especially near St. Patrick's Day. Throw in a simple salad or some roasted veggies if you want something more substantial. My kids love it as their first course, but it's filling enough to stand alone too.

Storing Leftovers
Stick any extra soup in an airtight container in your fridge—it'll stay good for about 3 days. When it's time to eat it again, heat it slowly on low, giving it a stir now and then. Don't rush with high heat—you'll just mess up all that lovely creaminess we worked for.
Try These Twists
You can throw in some celeriac or carrots instead of some parsnips—each veggie brings its own kind of sweetness. I sometimes swap spinach for parsley when I want something a bit milder. Go with a lighter broth if you don't want it so rich, or try using coconut milk for a completely different but still creamy version.

Fancy Upgrades
Just a tiny bit of nutmeg or some fresh thyme sprigs can change the whole vibe of this soup. Try adding a dollop of crème fraîche or thick Greek yogurt on top for extra luxury. My hubby can't get enough of it with crunchy bacon pieces scattered over his bowl, but I prefer some lightly toasted pine nuts on mine. Do whatever makes you happy—that's the best part about cooking at home.
Frequently Asked Questions
- → What's the best way to wash leeks?
Cut them open lengthwise, then rinse thoroughly between the layers where dirt might hide.
- → Do I need to remove parsnip cores?
If they're from late harvest and feel tough or woody when cutting, it's best to cut the cores out.
- → Can I prepare this soup in advance?
Absolutely! It stores in the fridge 3-4 days. You might need to add a little liquid when warming it up.
- → Why add lemon zest separately?
Cooking with zest infuses a gentle flavor, while squeezing fresh juice at the end adds brightness that isn't bitter.
- → Can I use a regular blender?
Sure! An immersion blender is just more convenient. If using a stand blender, divide the soup into smaller portions to avoid spills.
