Parsnip and Herb Soup

The smell of roasting parsnips drifting through the kitchen on a gray Sunday morning is something that instinctively makes me reach for my slippers. This soup started as an experiment with a forgotten bag of root vegetables from the back of the crisper drawer. I roasted them simply with onion and garlic, expecting something ordinary. What emerged from the blender was this incredibly silky, golden bowl of comfort that has since become my go-to when I need something warming but not heavy.

My sister was visiting during a particularly bleak February when I first made this for guests. She took one sip, looked up with surprised eyes, and asked if this was really just humble parsnips. We ate it huddled around the kitchen table while rain drummed against the window, and she made me promise to write down exactly what I had done. Now whenever she comes over, she requests it before even taking her coat off.

Ingredients

• 800 g parsnips: Roasting concentrates their natural sweetness and mellows any bitter notes
• 1 medium onion: Adds aromatic depth that balances the parsnips sweetness
• 2 garlic cloves: Roast them alongside the vegetables for mellow sweetness rather than raw bite
• 1 medium potato: The secret to extra creaminess without adding more dairy
• 1 L vegetable stock: Use a quality stock you would drink on its own
• 200 ml milk or plant milk: Whole milk gives the richest body but oat milk works beautifully
• 2 tbsp olive oil: Helps the vegetables caramelize and develop those golden edges
• 1 bay leaf and 1 tsp fresh thyme: Classic herbs that complement without overpowering
• ½ tsp ground white pepper: White pepper keeps the soup pristine in appearance
• Salt to taste: Parsnips need more salt than you might think
• 2 tbsp each chopped fresh parsley, chives, and 1 tbsp dill: This herb trio is the finish that makes the soup sing

Instructions

Roast the foundation:

Preheat your oven to 200°C (400°F) and toss the parsnips, onion, and garlic with olive oil. Spread them in a single layer on a baking tray and roast for 25 to 30 minutes, turning halfway through. You want them deeply golden and tender at the edges.

Build the base:

Transfer the roasted vegetables into a large saucepan. Add the diced potato, bay leaf, thyme, white pepper, and vegetable stock. Bring everything to a gentle boil, then reduce the heat and let it simmer for about 15 minutes until the potatoes are completely soft.

Puree to perfection:

Fish out and discard the bay leaf. Blend the soup until it is utterly smooth and no bits remain. An immersion blender works well here, but a stand blender gives the silkiest texture.

Add the creaminess:

Return the soup to the pan and stir in the milk. Gently reheat everything without bringing it to a boil. Taste and season generously with salt until the flavors really pop.

Finish with fresh herbs:

Stir in the chopped parsley, chives, and dill right at the end. Ladle into warmed bowls and finish with extra herbs and a drizzle of olive oil or cream if you like.

Pin It

This soup has become the thing I make when friends need feeding through tough times. There is something about its gentle warmth and unpretentious nature that feels like a hug in a bowl. More than one person has told me it tastes like something their grandmother would have made.

Making It Your Own

A pinch of nutmeg stirred in at the end adds subtle warmth that surprises people. I once added a small roasted apple with the vegetables, which created a lovely fruity note. Curry powder works beautifully too if you want to take it in a different direction.

Serving Suggestions

Crusty bread is nonnegotiable here. Something with a good chewy crust for dipping. A light green salad with sharp vinaigrette cuts through the creaminess. For a more substantial meal, a goat cheese tart on the side makes it feel like dinner party fare.

Make Ahead Success

This soup actually improves after a day in the refrigerator, which makes it perfect for entertaining. Make it up to two days ahead and reheat gently. The flavors meld together beautifully and the texture becomes even smoother.

• Add the fresh herbs just before serving so they stay vibrant
• Thin with a little extra stock or milk when reheating as it continues to thicken
• Freeze without the milk and add it when you reheat for the best texture

There is something deeply satisfying about turning such humble ingredients into something this elegant. This soup is proof that comfort food does not have to be complicated.
