Celeriac Puree with Leek and Pecorino

Peel the celery root first — that’s the annoying part, but it goes fast with a sharp knife. Three quarters of an hour total if you move steady. Forty-five minutes. The rest just happens while you’re standing there.

Why You’ll Love This Celeriac Puree

Tastes like you spent way longer than you did. Smooth. Doesn’t feel heavy even though it’s basically root vegetables and cheese. Works as a side for literally anything — roasted chicken, fish, just bread and good butter. Nobody knows what celery root is until they eat this, then they want the recipe. Vegetarian. Gluten free. Brings something interesting to the table without being weird about it. One pan, one pot, one processor. Cleanup’s maybe five minutes total.

What You Need for Celery Root Puree

Celery root. Not celery stalks alone — the root’s where the magic is. Sweet, subtle, less aggressive than regular celery. Get a big one, peel it rough, cube it up. You want about a litre and a half once it’s peeled. Celery stalks sliced thin — use the pale inner parts, throw the tough outer ones in stock. Four garlic cloves. A medium leek, just the white and light green — dark green gets bitter. Olive oil. Good olive oil works. The cheap stuff’s fine too. Pecorino Romano cheese, grated. Sharp. You could use Parmesan. Not the same, but works. Salt. Black pepper, cracked coarse. Optional nutmeg — barely a pinch, like you almost didn’t add it.

How to Make Celeriac Root Puree

Set up a steamer basket over simmering water. Get it going before you touch the vegetables. Dump the cubed celery root and sliced stalks and garlic cloves in all at once, cover it tight. Steam for 25 minutes. Not longer. Not quite as long. Twenty-five. Test it halfway through — knife should slide through the root without pushing hard. If it still feels thick and fibrous, give it another few minutes. Stop checking after that or you’ll overcook it and the whole thing goes gluey and sad.

While that’s happening, heat olive oil in a skillet over medium. Not high. Medium. Add the sliced leek and stir it around. Eight minutes. Watch for the edges to go soft and pale gold — that’s caramelization, that’s when you pull it. Burnt tastes horrible. One second of black and the whole thing’s bitter and you’re starting over. Don’t let that happen.

How to Get Celeriac Puree Smooth and Silky

Pour everything into the food processor. The steamed vegetables, the garlic, the leek. Add the grated Pecorino. Pulse. Don’t just turn it on and walk away. Pulse and stop, pulse and stop. Scrape the sides down every few pulses. You’re looking for completely smooth — velvety, no strings, no chunks catching your tongue. Takes maybe three minutes of pulsing. If it’s too thick, add hot water a splash at a time. Or vegetable broth if you have it. Broth tastes better. Water works fine.

Taste it now. Salt might need to go up. Pecorino’s salty and sharp, sharper than Parmesan, so go easy. Crack some black pepper in. The nutmeg — just a whisper. Most people can’t place the nutmeg in the taste. That’s the point. Just makes it taste like something you can’t quite name.

Celeriac Puree Tips and Common Mistakes

Steaming matters more than boiling. Boiling makes it waterlogged. Steaming keeps it dense. Texture stays right. Don’t skip tasting before you serve it. Seasoning changes everything and you can’t unfold salt. The leek can char a tiny bit if you’re not paying attention. Not the end of the world — it adds depth. But burnt is burnt. If you’re making this ahead, cool it first, then refrigerate. Reheats gentle — low heat, stir it, add a splash of water if it’s gotten stiff. Keeps three days easy. Might keep four. Don’t leave it longer than that.

Celeriac Puree with Leek and Pecorino

By Emma

Prep:

20 min

Cook:

25 min

Total:

45 min

Servings:

4 servings

Ingredients

• 1.2 litres celery root peeled and cubed
• 600 ml celery stalks sliced thin
• 4 garlic cloves peeled
• 1 medium leek, white and light green parts sliced
• 45 ml olive oil
• 100 ml grated Pecorino Romano cheese
• Salt and cracked black pepper to taste
• Optional pinch of nutmeg

Method

1. 1 Set up a steaming basket over simmering water. Place the cubed celery root, celery stalks, and garlic in, cover tightly. Steam gently for about 25 minutes, testing tenderness: a sharp knife should slide in without resistance; if it still feels fibrous or crunchy, keep steaming, checking every 3-5 minutes. Overcooking can make the purée gluey.
2. 2 Meanwhile, heat olive oil in a skillet over medium heat. Add sliced leek, stirring often. Watch for soft edges and slight caramelization, about 8 minutes. Take care not to burn; burnt leek turns bitter instantly.
3. 3 Transfer steamed veggies and garlic into a food processor. Add sautéed leek (reserve a bit for garnish if you like), Pecorino cheese, and start pulsing. Don't rush pureeing — stop frequently to scrape down sides. Texture should be velvety, not stringy or chunky. If too stiff, add hot water or a splash of vegetable broth to loosen.
4. 4 Season with salt, pepper, and a whisper of nutmeg if on hand. Taste. Parmesan is punchy; Pecorino is sharper, so adjust salt accordingly. The purée should hold together but still feel light on the tongue.
5. 5 Serve warm, garnished with remaining leek and cracked pepper. Can cool and refrigerate; reheat gently to keep texture intact.

Frequently Asked Questions About Celery Root Puree

Can I make this celeriac root puree ahead of time? Yeah. Cool it completely first, then store it covered in the fridge for three days. Reheat low and slow, add a splash of water to loosen it if it’s thick. Don’t blast it on high heat or the texture gets weird.

What if I can’t find celery root? You’ve got options. Celeriac is the same thing, just the British word for it. If neither’s at the store, potato mixed with what celery you can get works. Not the same. Closer than nothing.

Do I have to use Pecorino Romano? Parmesan works. Less sharp. Gruyere works too, gets almost sweet. The cheese is just seasoning and richness. Any hard cheese that grates fine will do something.

Can I add cream? Sure. Heavy cream loosens it and makes it richer. Not necessary though. The olive oil does the job.

How does this celery root and potato combination work? If you go half celery root, half potato, you get something earthier and less mineral-tasting. Potatoes lighten it. Takes the same time to cook — just cube the potato the same size.

Why did my puree get gluey? Overcooking. The fibers break down too much and release starch. Watch the steaming time. Twenty-five minutes exactly if you can. If you went longer, nothing fixes it.
