Celeriac Puree with Parsnip & Crème Fraîche

Peel the celeriac first — it’s tougher than it looks. The knife should be sharp. Grab a medium-large one, about the size of a small fist, and work around it steadily. Parsnip and carrot go in too, which sounds like a side dish but tastes like comfort food. Forty-five minutes total and you’re done.

Why You’ll Love This Celeriac Puree

Goes warm or cold, so it fits anywhere on the plate. Leftover roasted chicken? Grilled fish? Works with both. Side dish that doesn’t need anything else but tastes better with something. Not heavy like mashed potatoes — creamier but still feels like actual vegetables. Takes 15 minutes to prep if you move fast, 30 minutes cooking. The lemon zest at the end is what makes it land. One pot. Most of it’s hands-off while it simmers. Reheats gentle, doesn’t dry out, tastes maybe better the next day.

What You Need for Celery Root Puree

Celeriac root — 500 grams, peeled and cubed. The knobby ones. Not the prettiest vegetable but it purées silky. Parsnip, about half a medium one, peeled and cubed too — adds sweetness without being obvious about it. One medium carrot, same treatment. Crème fraîche, 120 millilitres. This matters more than butter. Olive oil, the good kind, 30 millilitres. Not extra virgin if you’re adding heat later, but this goes in off the heat so it doesn’t matter. Sea salt — a teaspoon to start, then more when you taste it. Lemon zest from one lemon. That’s the brightness.

How to Make Celeriac Puree

Fill a pot deep enough with salted water — about 2 centimetres over the vegetables once they go in. Boil it. The vegetables get dropped in: celeriac first if you want to be fussy about it, but they all go in at once and nobody’s timing it precisely. Gentle simmer, not a rolling boil. The difference matters. Turbulent water breaks them apart. You want them to stay in cubes until they’re soft, not turn into mush halfway. Twenty-five to 30 minutes. Check by stabbing a piece with a small knife — if it slides through with barely any push, it’s done. A little resistance is fine.

Drain them. This part matters. Use a colander or just pour carefully. Get the water off. Put them back in the empty pot with the lid cracked — not fully closed — for three minutes. Steam off the extra moisture that’s clinging to them. Wet vegetables make gluey puree. You don’t want gluey.

How to Get Celeriac Puree Creamy and Smooth

Transfer to a food processor in batches. Two or three batches depending on your machine. Cramming it all in at once doesn’t work. Add the crème fraîche and olive oil. Start pulsing slow, then increase speed. Scrape the sides two, three times while it’s going — makes sure nothing hides at the bottom and stays chunky while the rest goes smooth. The texture should be creamy but still slightly rustic. Not like baby food. Not like wallpaper paste. There’s a middle ground and you’ll feel it.

Season with salt now. Taste it. Might need more. Probably does. Salt changes everything here because the vegetables themselves don’t have much going on flavour-wise — they’re neutral, which is the point. Then fold in the lemon zest. Gently. Just stir it through. This is what makes it taste like something you meant to make, not something that just happened.

Celeriac Puree Tips and Common Mistakes

Don’t skip the draining step. Sounds simple but watery puree is the biggest mistake. Boil the water off, drain hard, steam it dry. Then blend. That’s the order. Crème fraîche over butter here because it’s more forgiving. Stays smooth. Butter can get greasy if you’re heavy-handed and it’s harder to control once it’s blended. Crème fraîche just works. If it comes out too thick — and it might depending on how wet your vegetables were — loosen it with warm water or broth. A splash at a time. Easier to add than take back. Leftovers go in a double boiler to reheat, low and slow. Microwave works if you’re in a hurry but it dries it out faster. Keep the lid on either way. Stays better.

Celeriac Puree with Parsnip & Crème Fraîche

By Emma

Prep:

15 min

Cook:

30 min

Total:

45 min

Servings:

4 servings

Ingredients

• 500 g cubes peeled celery root (1 medium-large celery root)
• 100 g cubes peeled parsnip (about half a parsnip)
• 100 g cubes peeled carrot (1 medium carrot)
• 120 ml crème fraîche
• 30 ml good-quality olive oil
• 1 teaspoon sea salt plus more to taste
• grated zest of 1 lemon

Method

1. 1 Fill a deep pot with salted water — enough to cover vegetables by at least 2 cm.
2. 2 Bring to a boil. Toss in celery root, parsnip, carrot cubes. Simmer gently rather than boiling hard — bubbling not turbulence. Cook 25-30 minutes until tender but intact. Check often by piercing with small knife: should slide in with a little resistance fading.
3. 3 Drain quickly. Steam off excess moisture by putting vegetables back in pot off heat, lid ajar for 3 minutes.
4. 4 Transfer warm veggies to a food processor or blender in 2-3 batches for easier pulsing.
5. 5 Add crème fraîche and olive oil. Pulse slowly increasing speed. Scrape sides 2-3 times during blending to ensure even pureeing.
6. 6 Texture should be creamy, slightly rustic, not gluey. Season with salt, adjust to taste.
7. 7 Fold in grated lemon zest for a brightness contrast; stir gently.
8. 8 Serve warm or at room temperature.
9. 9 If too thick, loosen with splash of warm water or broth.
10. 10 Leftovers reheat gently in double boiler or low microwave to avoid drying.

Frequently Asked Questions About Celery Root Puree

Can I make this ahead? Yeah. Stores three, maybe four days in the fridge covered. Tastes fine cold, reheats better. Make it the day before if you’re doing a dinner thing.

What if I don’t have crème fraîche? Sour cream works. Greek yogurt works but it’s thinner. Butter alone doesn’t get you the same texture. Crème fraîche is worth finding.

Do I have to use all three vegetables? No. Celeriac root puree is fine on its own but it tastes flatter. The carrot adds a hint of sweetness, parsnip does the same thing. Both together balances it. Root puree with just one extra vegetable still works though.

Why does mine come out grainy? Not cooked through. Pierce with the knife — should slide easy. Or your food processor isn’t running long enough. Pulse longer. Stop when it’s smooth, not before.

Can I make celery root and potato puree instead? Could do. Potato makes it heavier, less interesting. Celeriac puree stays lighter, tastes more like itself. If you want to add potato, use half and half — half celeriac, half potato — don’t flip it.

Does the lemon zest matter? Yeah. It does. Without it you’re eating a side dish. With it you’re eating a side dish that makes sense. Don’t skip it.

What’s the difference between celery root puree recipe versions? This one’s simple. Celeriac puree recipes get complicated with roasted garlic or truffle oil or whatever. This one’s just the vegetable tasting like the vegetable.
