How Do You Cook Celery Root

You cook celery root by peeling it first, then cutting it into cubes, slices, or matchsticks depending on the dish you have in mind.
 
From there, you can roast it, boil it, mash it, purée it into soup, or even eat it raw when it’s shaved thin.
 
If you’ve ever stared at a knobby celery root in the produce aisle and wondered how to cook celery root without making a mess, you’re in the right place.
 
In this post, we’ll walk through exactly how to cook celery root, from prepping it properly to the best cooking methods that bring out its nutty, earthy flavor.
 
Let’s get into it.
 

How Do You Cook Celery Root? Here’s the Answer

You cook celery root by treating it like a cross between a potato and a turnip, which means it works beautifully in almost any cooking method you already know.
 
The key is knowing how to prep it, because that rough, knobby exterior can be intimidating if you’ve never handled one before.
 
Once it’s peeled and cut, cooking celery root becomes as easy as cooking any root vegetable.
 
Here’s why it’s such a versatile ingredient to cook with.
 

1. It Holds Its Shape When Roasted

When you roast celery root, it develops a golden, caramelized exterior while staying creamy on the inside.
 
This makes it perfect for sheet pan dinners alongside carrots, onions, and potatoes.
 
Toss the cubes with olive oil, salt, and pepper, then roast at 425°F for about 30 to 40 minutes.
 
The natural sugars concentrate as it cooks, giving you a sweet, nutty flavor that’s hard to resist.
 

2. It Turns Silky When Boiled and Mashed

If you want to cook celery root into a smooth mash, boiling is your best friend.
 
Peel and cube the root, then simmer it in salted water until a fork slides through easily, usually 15 to 20 minutes.
 
Drain it well, then mash it with butter, cream, and a pinch of nutmeg.
 
You can also blend it with potatoes for a lighter, more complex take on classic mashed potatoes.
 

3. It Blends Into Velvety Soups

One of the easiest ways to cook celery root is to simmer it into a soup.
 
Sauté onions and garlic, add peeled celery root cubes and broth, then simmer until tender.
 
Blend everything until smooth, and you’ll get a velvety soup that tastes fancy but took almost no effort.
 
A drizzle of cream or olive oil on top finishes it beautifully.
 

How to Prep Celery Root Before You Cook It

Before you cook celery root, you’ve got to deal with that tough, hairy skin, and skipping this step will ruin your dish.
 
Here’s the simplest way to get it ready.
 

1. Slice Off the Top and Bottom

Lay the celery root on a cutting board and cut off both ends with a sharp knife.
 
This gives you a stable base so the root doesn’t roll around while you’re working.
 

2. Peel Away the Rough Skin

Use a sharp chef’s knife or a sturdy vegetable peeler to remove the thick, knobby outer layer.
 
Don’t be shy here, because the skin is tough and stringy, and you want to expose the pale, creamy flesh underneath.
 

3. Cut It Into Even Pieces

Once peeled, cut the celery root into cubes, slices, or matchsticks, depending on how you plan to cook it.
 
Try to keep the pieces roughly the same size so they cook evenly.
 

4. Keep It in Lemon Water

Celery root browns quickly once it’s cut, so drop the pieces into a bowl of cold water with a squeeze of lemon juice.
 
This keeps the color fresh while you finish prepping the rest of your ingredients.
 

Other Delicious Ways to Cook Celery Root

Beyond roasting, mashing, and soups, there are plenty of creative ways to cook celery root that are worth trying.
 

1. Raw in Salads

You can cook celery root, but you can also enjoy it raw when it’s shaved paper-thin.
 
Toss the shavings with lemon juice, olive oil, mustard, and fresh herbs for a crunchy, bright salad.
 

2. As a Gratin

Layer thin slices of celery root with cream, garlic, and Gruyère cheese, then bake until bubbly.
 
This is one of the most comforting ways to cook celery root during colder months.
 

3. Fried Into Crispy Chips

Slice it thinly, fry the pieces until golden, and sprinkle with sea salt.
 
These chips are a fantastic snack and a fun way to cook celery root for skeptics.
