Celery root, when peeled and cubed, becomes a creamy, earthy base for pureed soups or roasted side dishes. If you have ever wondered how to cook celery root, you are in the right place. This knobby, ugly-looking vegetable is actually a kitchen superstar. It tastes like a mix of celery and parsley, with a nutty undertone. You can mash it, roast it, or turn it into a silky soup. Let us walk through everything you need to know.
What Is Celery Root And Why Cook It?
Celery root, also called celeriac, is a root vegetable from the same family as celery. It looks rough and bumpy on the outside, but inside it is white and crisp. It is low in calories and high in fiber, vitamin K, and phosphorus. Cooking it brings out a mild, sweet flavor that pairs well with herbs and cream. Many people avoid it because they do not know how to handle it. But once you learn the basics, you will want to use it all winter long.
Selecting The Best Celery Root
Pick celery roots that feel heavy for their size. Avoid ones with soft spots or too many roots growing off them. Smaller ones tend to be more tender. The skin should be firm, not wrinkled. Fresh celery root smells clean and earthy, not sour.
Tools You Will Need
- A sharp chef’s knife
- A vegetable peeler or paring knife
- A cutting board
- A large bowl of cold water with lemon juice (to prevent browning)
- A pot, baking sheet, or skillet depending on the method
How To Cook Celery Root: Preparation First
Before you start cooking, you must prep the celery root properly. This is the most important step. The skin is thick and tough, so do not skip it. Cut off the top and bottom of the root with a knife. Stand it upright on a flat end. Slice off the skin in strips from top to bottom, following the curve of the vegetable. You will lose some flesh, but that is normal. Rinse the peeled root under cold water. Cut it in half, then into slices, and finally into cubes. Put the cubes in the lemon water to keep them white.
Why Lemon Water Helps
Celery root oxidizes quickly, turning brown like an apple. The acid in lemon juice slows this down. If you do not have lemon, use a splash of vinegar. This step is not required if you cook it right away, but it helps if you prep ahead.
Roasted Celery Root: Simple And Nutty
Roasting is one of the easiest ways to cook celery root. The high heat caramelizes the natural sugars, making it sweet and tender. Preheat your oven to 400°F (200°C). Toss the cubed celery root with olive oil, salt, and pepper. Spread them in a single layer on a baking sheet. Roast for 25 to 30 minutes, flipping halfway through. They should be golden brown on the edges and soft inside. You can add garlic cloves or fresh thyme for extra flavor.
Roasted Celery Root Variations
- Add chopped carrots or parsnips for a mixed root roast
- Drizzle with balsamic vinegar before serving
- Sprinkle with parmesan cheese in the last 5 minutes
Celery Root Mash: Creamy And Comforting
Mashed celery root is a lower-carb alternative to mashed potatoes. It is lighter and has a subtle celery flavor. Peel and cube the celery root into 1-inch pieces. Boil them in salted water for 15 to 20 minutes until fork-tender. Drain well, then return to the pot over low heat for a minute to dry out. Mash with a potato masher or use a food processor. Add butter, cream, salt, and pepper. You can also mix in a little cooked potato for a fluffier texture. Serve warm with roasted meat or as a side for stews.
Tips For Perfect Mash
- Do not overcook; mushy celery root becomes watery
- Drain very well to avoid a runny mash
- Use warm cream and butter for better incorporation
Celery Root Soup: Silky And Elegant
Celery root soup is a classic way to use this vegetable. It is smooth, creamy, and deeply satisfying. Start by sautéing a diced onion and two cloves of garlic in butter or oil until soft. Add 4 cups of peeled and cubed celery root. Pour in 4 cups of vegetable or chicken broth. Bring to a boil, then simmer for 20 minutes until the celery root is tender. Use an immersion blender to puree until smooth. Stir in ½ cup of heavy cream or coconut milk. Season with salt, white pepper, and a pinch of nutmeg. Garnish with chives or crispy bacon bits.
Soup Variations
- Add a peeled apple for sweetness
- Use coconut milk for a dairy-free version
- Top with roasted pumpkin seeds for crunch
Pan-Fried Celery Root: Crispy On The Outside
Pan-frying gives celery root a crispy crust while keeping the inside tender. Cut the peeled root into thin rounds or matchsticks. Heat a skillet with oil or butter over medium-high heat. Add the celery root in a single layer. Cook for 4 to 5 minutes per side until golden and crispy. Season with salt and pepper. You can also toss them with herbs like rosemary or sage after cooking. This method works great as a side for fish or chicken.
Quick Pan-Fry Tips
- Slice evenly for consistent cooking
- Do not overcrowd the pan; cook in batches
- Pat dry with a paper towel before frying to avoid splatter
Steamed Celery Root: Light And Healthy
Steaming preserves the delicate flavor of celery root without adding fat. Cut the peeled root into cubes or slices. Place them in a steamer basket over boiling water. Cover and steam for 10 to 15 minutes until tender. Check with a fork. Serve with a drizzle of olive oil, lemon juice, and fresh parsley. Steamed celery root is great in salads or as a simple side dish.
Steamed Celery Root Salad Idea
Let the steamed cubes cool. Toss them with arugula, shaved parmesan, toasted walnuts, and a lemon vinaigrette. This makes a light lunch or starter.
Celery Root In Stews And Braises
Celery root holds up well in long cooking. Add it to beef stew, chicken braise, or vegetable soup. Cut it into chunks similar to the other vegetables. Add it in the last 30 minutes of cooking so it does not turn to mush. It absorbs the broth flavors and adds a subtle celery note. You can also use it in place of potatoes in many recipes.
Braised Celery Root With Herbs
In a heavy pot, melt butter and add sliced celery root. Cook for 5 minutes. Add a cup of broth, a sprig of thyme, and a bay leaf. Cover and simmer for 20 minutes. Uncover and cook until the liquid reduces to a glaze. Serve as a side for pork or lamb.
Raw Celery Root: Crunchy And Fresh
You can eat celery root raw. It is crisp and has a mild celery flavor. Peel it and grate it into a salad. Mix with shredded apple, carrots, and a mustard vinaigrette. Or slice it thinly and add to slaws. Raw celery root works well in remoulade, a classic French dish. For that, mix grated celery root with mayonnaise, mustard, lemon juice, and capers. Let it sit for 30 minutes before serving.
Celery Root Remoulade Recipe
- 1 large celery root, peeled and grated
- 3 tablespoons mayonnaise
- 1 tablespoon Dijon mustard
- 1 tablespoon lemon juice
- 1 tablespoon capers, chopped
- Salt and pepper to taste
Mix everything together. Chill for at least an hour. Serve on lettuce leaves or as a side for grilled fish.
Storing Cooked Celery Root
Cooked celery root keeps in the fridge for 3 to 4 days. Store it in an airtight container. Reheat in a skillet or microwave. You can also freeze it. Mashed or pureed celery root freezes well for up to 3 months. Roasted pieces may lose some texture after freezing, but they still work in soups.
How To Freeze Celery Root
Blanch peeled cubes in boiling water for 2 minutes. Drain and cool in ice water. Pat dry and freeze in a single layer on a baking sheet. Transfer to a freezer bag. This method prevents clumping.
Common Mistakes When Cooking Celery Root
- Not peeling enough: The skin is tough and fibrous, so remove it all
- Skipping the lemon water: This leads to brown, unappealing pieces
- Overcooking: Celery root can turn mushy and watery if boiled too long
- Underseasoning: It needs salt and fat to bring out its flavor
- Using old celery root: Fresh ones are firmer and taste better
