What Is Celeriac?

Celeriac, also known as celery root, is the swollen root of the celery plant. It’s a versatile vegetable that can be eaten raw or cooked. With a mild, celery-tinged flavor and a firm texture when raw, it makes a great alternative to potatoes in many dishes and is popular in Northern and Eastern European cooking.

What Does Celeriac Look Like?

Celeriac is lumpy and round, roughly the size of a grapefruit or small softball. When sold by itself you’ll see a rough brown exterior with small rootlets and a somewhat dirty appearance — that’s normal for a root vegetable. Inside, the flesh is pale and smooth, similar to jicama in appearance. Choose bulbs that feel firm and avoid any with slimy or spongy spots; if only a small area is soft you can cut it away and use the rest.

What Does Celeriac Taste Like?

Celeriac has an earthy, slightly nutty flavor with a fresh celery note. Raw, it’s crunchy and crisp — ideal for salads and slaws. Cooked, it softens and sweetens, becoming creamy when mashed or tender when roasted.

Substitutes

Celeriac can often replace potatoes for a more nutrient-dense option. Parsley root is a good flavor-forward substitute, while jicama or celery can mimic the crunchy texture in raw preparations. Note that celery won’t soften like celeriac when cooked, and jicama has a fruitier taste and won’t become as creamy after boiling.

Where to Find Celeriac

Celeriac is grown in many regions and can be found at farmers markets and in grocery store produce sections, often near other root vegetables. Its peak season runs from fall through early spring, so you’re more likely to spot it during those months.

How to Prepare and Cook With Celeriac

  1. Remove the ends: Trim the top and bottom of the root with a sharp knife.

  1. Peel: Use a sturdy vegetable peeler or a paring knife to remove the rough skin. A peeler may require several passes; a paring knife gives more control around the curves.
  2. Chop: Slice, dice, or julienne the peeled celeriac according to your recipe.

  1. Prevent oxidizing: Celeriac browns quickly after peeling. If you need to hold it, submerge the cut pieces in cold water with a splash of lemon juice to keep the flesh from discoloring.

How to Store Celeriac

Uncut, celeriac will keep for about three weeks in the refrigerator’s crisper drawer. Store it unwashed in a plastic bag or airtight container. To freeze, blanch peeled and sliced celeriac in salted boiling water for two minutes, then shock in ice water, dry, and freeze in a sealed bag for several months.

FAQs

How do you mash celeriac?

Cut celeriac into chunks and boil until tender. Drain, then mash with butter, cream or milk, salt and pepper. Add herbs or a bit of garlic for extra flavor. Mixing celeriac with potatoes makes a lighter mash.

Do you need to peel celeriac?

Peeling is recommended for texture and appearance, though the skin is technically edible. If you leave it on, scrub thoroughly to remove dirt.

Carrot Celeriac Remoulade

Remoulade is a classic French-style creamy dressing. This version is thinned into a dressing with vinegar and a touch of hot sauce, then brightened with capers, parsley, and scallion. It’s crisp, flavorful, and a lovely side for fish or roasted meats.

Ingredients

For the dressing:

  • Mayonnaise — the creamy base.
  • Dijon mustard — adds texture and a gentle bite.
  • Red wine vinegar — turns the sauce into a dressing.
  • Hot sauce — start small and adjust to taste.
  • Capers — drained and chopped for briny brightness.
  • Parsley — finely chopped flat-leaf parsley for freshness.
  • Scallions — white and green parts, minced.

For the salad:

  • Celeriac — peeled and julienned or shredded.
  • Carrots — peeled and shredded.
  • Fresh lemon juice — a splash to brighten and prevent browning.
