Classic Celeriac Purée (Celery Root Purée) — Silky Steakhouse Side

Ingredient Spotlight

Celeriac (celery root), peeled and cut into 1" cubes

Celeriac is the knobby root of a celery variety, long used in European cooking (notably French). It has an earthy, slightly nutty flavor with a mild celery note and a starchy texture well suited to mashes, purees and braises. You can find it in the produce section of larger supermarkets, specialty grocers or farmers' markets; look for firm, heavy roots without soft spots. If you can't find it, substitute peeled potatoes or parsnips combined with a few chopped celery stalks to add the celery character.

Ingredient Spotlight

Freshly grated nutmeg

This refers to whole nutmeg grated fresh rather than pre-ground; nutmeg is a warm, sweet, aromatic spice originally from the Banda Islands (Moluccas). Freshly grated nutmeg is more fragrant and complex than pre-ground and is traditionally used in cream sauces, egg dishes and root-vegetable purées. Whole nutmeg is sold in the spice aisle at most grocery stores and specialty shops. If you don't have whole nutmeg, use a pinch of ground nutmeg (start with less) or mace (the nutmeg’s outer aril) as the closest substitute.

Ingredient Spotlight

White pepper (or black), ground

White pepper is made from ripe peppercorns with the outer skin removed, and is common in European and some Asian cuisines where a milder, less floral pepper note and a pale appearance in sauces is desired. It tastes earthier and slightly fermented compared with black pepper and is often used in light-colored purées and cream sauces to avoid dark specks. You can find ground white pepper in the spice aisle or whole white peppercorns in specialty shops. If unavailable, use ground black pepper (it will be bolder and will leave dark flecks) or reduce the amount to avoid overpowering delicate dishes.

Jake's note

"This purée is deceptively simple—silky texture comes from a hot blender and a bit of patience. It’s an ideal side for special-occasion steaks or Sunday roasts and scales easily for a crowd."

Classic Celeriac Purée (Celery Root Purée) — Silky Steakhouse Side

Celeriac purée reads like a steakhouse secret: it’s luxuriously silky and subtly nutty, but with a brightness that keeps it from feeling heavy. This version leans into those contrasts—rich butter and cream for mouthfeel, a judicious squeeze of lemon and a whisper of fresh nutmeg to lift the root’s earthy sweetness. Simmering the cubes gently keeps the interior creamy while preserving that mild celery-like aroma, and working the vegetable while it’s hot plus a quick pass through a sieve are the two simple moves that give the result its restaurant-level silk.

It’s an excellent alternative to mashed potato when you want something lower in carbs but no less indulgent, and it’s forgiving enough for weeknight cooking yet elegant for a dinner party. If you prefer deeper, caramelized notes, roast the cubes before puréeing; if you need a dairy-free option, extra-virgin olive oil and unsweetened plant milk produce a surprisingly rich finish. Small adjustments—how much of the reserved cooking liquid you add, or whether you finish with olive oil or browned butter—let you tailor the purée to the main protein on your plate, from grilled ribeye to herb-crusted lamb.

Instructions

Peel and cube the celeriac; start the simmer

Trim and peel the celeriac and cut into roughly 1-inch (2.5 cm) cubes so they cook evenly. Place the cubes in a large saucepan and cover with cold water by about 1 inch; add 1 teaspoon of the kosher salt. Bring to a gentle boil over medium-high heat, then reduce to a simmer.

For this step

  • 2 lbCeleriac (celery root), peeled and cut into 1" cubes
  • 1.5 tspKosher salt
Peel and cube the celeriac; start the simmer

Cook until tender and reserve cooking liquid

Simmer the celeriac until very tender when pierced with a fork, about 18–25 minutes depending on cube size. Carefully drain, reserving up to 1 cup (240 ml) of the cooking liquid — you’ll use a little at a time to loosen the purée if needed.
Cook until tender and reserve cooking liquid

Blend to a silky purée with butter, cream, lemon and spice

While the celeriac is hot, transfer half to a blender or food processor with the butter, heavy cream, lemon juice, lemon zest, freshly grated nutmeg, the remaining 1/2 teaspoon salt and white pepper. Add 2–3 tablespoons of the reserved cooking liquid and blend until smooth and velvety, stopping to scrape the sides; add more warm cooking liquid a tablespoon at a time if it’s too thick. Work in the remaining cubes in a second batch and then combine, or blend the whole lot in a sufficiently large blender. Taste and adjust salt, pepper and lemon.

For this step

  • 4 tbspUnsalted butter
  • 0.5 cupHeavy cream
  • 1 tbspFresh lemon juice
  • 1 tspFresh lemon zest
  • 0.25 tspFreshly grated nutmeg
  • 0.25 tspWhite pepper (or black), ground
Blend to a silky purée with butter, cream, lemon and spice

Finish, strain if desired, and serve

For an extra-silky finish, push the purée through a fine-mesh sieve with a spatula. For a dairy-free version, substitute the butter + cream with 2–3 tablespoons extra-virgin olive oil and 1/4 cup (60 ml) unsweetened non-dairy milk or reserved cooking liquid, blending until smooth. Spoon onto plates, finish with a small drizzle of olive oil and a light grating of nutmeg if you like, and serve warm alongside roast or grilled beef.

For this step

  • 2 tbspExtra-virgin olive oil (for dairy-free option or finishing)
Finish, strain if desired, and serve

Make-ahead notes and roasted variation

Make ahead: cool completely, cover and refrigerate up to 3 days (reheat gently over low heat, stirring in a splash of cream or warm cooking liquid). Roasted variation: toss peeled cubes with 2 tbsp olive oil and 1/2 tsp salt, roast on a rimmed sheet at 425°F (220°C) for 30–40 minutes until caramelized and tender, then blend as above for a deeper, caramelized flavor.

Tips from the kitchen

Cut uniform 1-inch cubes

Evenly sized pieces ensure the celeriac cooks at the same rate so you avoid a chalky center while others fall apart.

Blend while still hot

Warm vegetables incorporate more smoothly into butter and cream, producing a silkier emulsion than cold ingredients will.

Use reserved cooking liquid

Add the hot cooking liquid a tablespoon at a time to loosen the purée without diluting flavor or breaking the emulsion.

Sieve for extra silk

Pushing the purée through a fine-mesh sieve removes any stringy fibers and gives a restaurant-style mouthfeel.

Season at the end

Salt, lemon, and nutmeg reveal themselves after blending, so adjust them last to avoid over-salting or overpowering the celeriac.

Variations & substitutions

Roasted Celeriac Purée

Roast the cubed celeriac at 425°F until caramelized for 30–40 minutes before blending to gain deeper, sweeter, roasted notes in the purée.

Horseradish and Mustard

Stir in 1–2 teaspoons prepared horseradish and a teaspoon Dijon after blending for a bright, steak-friendly bite.

Vegan Cashew Version

Soak 1/2 cup cashews and blend them with reserved cooking liquid and 2 tablespoons olive oil for a creamy, dairy-free result.

Brown Butter & Parmesan

Replace half the butter with browned butter and fold in 2 tablespoons finely grated Parmesan for a nutty, savory finish that complements beef.

Storage & make-ahead

Cool the purée completely before transferring to an airtight container; it will keep in the refrigerator for up to 3 days. Reheat gently over low heat on the stovetop or in a warm oven, stirring and thinning with a splash of cream or reserved cooking liquid to restore a silky texture. You can freeze the purée for up to 2 months—thaw overnight in the fridge and reheat slowly, as above.

What to serve with it

Serve generous quenelles of the purée spooned alongside a simply seasoned grilled steak, roast beef, or lamb chops, using it as a velvety base to catch pan juices or a red wine jus. Add roasted mushrooms, charred broccolini, or quick-pickled shallots for texture and acidity, and pair with a medium- to full-bodied red wine like Malbec or Bordeaux-blend to match the dish’s richness. Finish with a light drizzle of good olive oil or a few flakes of flaky sea salt for contrast.

Frequently asked questions

Can I make this ahead of time?

Yes—cool the purée completely, cover, and refrigerate for up to 3 days; reheat gently over low heat, stirring in a splash of cream or reserved cooking liquid to loosen it before serving.

Is it possible to freeze the purée?

You can freeze it for up to 2 months in a freezer-safe container; thaw overnight in the fridge and reheat slowly, adding liquid as needed to restore silkiness.

Why save the cooking liquid?

The reserved liquid carries dissolved starches and flavor that help thin the purée without watering it down, and its warmth keeps the emulsion smooth during blending.

Can I use a potato instead of celeriac?

You can substitute potato, but the flavor and texture will be different—potato yields a starchier, less aromatic purée, while celeriac provides a nutty, celery-like complexity.

How do I make this dairy-free but still rich?

Use extra-virgin olive oil (2–3 tablespoons) plus unsweetened plant milk or blended soaked cashews; finishing with a spoonful of miso or a squeeze of lemon can boost savory depth.
