Parsnip and Herb Soup

There's something about the smell of roasting parsnips that fills a kitchen with an unexpected warmth, a sweetness that sneaks up on you. I discovered this soup on a particularly grey afternoon when I wanted something comforting but not heavy, something that felt like a proper meal without all the fuss. The roasting step transforms these humble root vegetables into something almost caramelized, and then the herbs at the end bring it all to life with a brightness you won't expect.

I made this for my mum when she was recovering from a cold, and watching her face light up as she tasted it was worth every minute. She asked for seconds, which never happens, and then wanted the recipe immediately. That's when I knew this soup had crossed from being just another thing I made to something worth keeping in regular rotation.

Ingredients

• Parsnips (800 g, peeled and chunked): These are the star, and roasting them brings out a natural sweetness that rivals carrots in the best way.
• Onion and garlic (1 medium onion, 2 garlic cloves): They add depth to the background flavor without shouting over the parsnips.
• Potato (1 medium, diced): This creates the creamy texture without needing cream or extra thickener.
• Vegetable stock (1 L): Use a good quality stock because it's the foundation, and every sip will taste it.
• Whole milk or plant-based milk (200 ml): Added at the end for richness and smoothness, but don't boil it or you'll break the silkiness.
• Olive oil (2 tbsp): Good olive oil matters here for both roasting and drizzling at the end.
• Bay leaf, thyme, white pepper: Bay gives you a subtle background note, thyme ties everything together with earthiness, and white pepper keeps the soup looking pristine.
• Fresh parsley, chives, and dill: These are what make people say 'what's in this,' they brighten everything up at the very last moment.

Get your oven ready and prep the vegetables:

Preheat to 200°C (400°F) while you peel and chunk the parsnips, chop the onion, and peel the garlic cloves. Having everything ready before you start makes the next step so much smoother.

Roast until golden and tender:

Toss the parsnips, onion, and garlic with olive oil on a baking tray and roast for 25 to 30 minutes, turning them halfway through. You'll know they're ready when they're golden at the edges and fork-tender, and your kitchen will smell incredible.

Build the soup base:

Transfer the roasted vegetables to a large saucepan and add the diced potato, bay leaf, thyme, white pepper, and vegetable stock. Bring everything to a boil, then turn the heat down and simmer gently for 15 minutes until the potatoes are completely soft.

Make it smooth and creamy:

Fish out the bay leaf, then use a blender or immersion blender to blend the soup until it's completely smooth. This is where the potato does its magic, creating that luxurious texture.

Add the milk and reheat gently:

Return the soup to the pan and stir in the milk, then reheat gently without letting it boil. Season with salt to taste, and at this point you can already smell how good this is going to be.

Finish with fresh herbs and serve:

Stir in the chopped parsley, chives, and dill just before serving, then ladle into bowls and add a final drizzle of olive oil or cream if you fancy it. The fresh herbs are the moment where everything clicks into place.

There's a quiet moment when everything comes together, when you've stirred in those final herbs and the color shifts from pale cream to something with flecks of green throughout. It's silly but it feels like magic, and somehow that soup tastes better because of it.

Why Roasting Changes Everything

Raw parsnips are fine, but roasted ones are a completely different ingredient. The dry heat of the oven concentrates their natural sugars and creates edges that turn caramel-colored, adding depth that you could never get from just simmering them in stock. It's one of those cooking tricks that feels simple once you know it, but makes all the difference when you taste it.

Making It Your Own

This soup is forgiving enough to adapt to what you have on hand. If you don't have dill, skip it, the parsley and chives do the work. If nutmeg is calling to you, add a small pinch after blending, it brings warmth without overwhelming anything. The base is solid enough that it can take small changes without falling apart.

Serving and Pairing Ideas

Serve this as a starter before something lighter, or make a bowl of it the main event with good bread on the side. It pairs beautifully with a crisp Sauvignon Blanc or dry cider if you're feeling fancy, but honestly it's also perfect with just a glass of water and good company. A light salad alongside works too, something peppery to contrast with the soup's sweetness.

• Crusty bread or toasted sourdough on the side makes it feel like a proper meal.
• A squeeze of fresh lemon juice just before serving adds brightness if you want to wake it up.
• Make a double batch and freeze half for those moments when you need comfort food fast.

Parsley, chives, and dill provide fresh brightness. You can substitute with tarragon for anise notes or add basil for a different flavour profile.
