Roast celeriac works best when peeled deeply, cut into thick wedges, tossed with oil and salt, and roasted at 425°F (220°C) with space between pieces. The outside browns while the center turns soft and creamy.
Celeriac does not look like an easy vegetable, but it roasts beautifully once the rough skin is gone. The edges caramelize, the center softens, and the flavor turns mellow and slightly nutty.
The two details that matter are peeling and spacing. Shallow peeling leaves fibrous patches. Crowding the tray traps steam. Peel deeper than feels polite, cut thick wedges, and give each piece room to brown.

Recommended Sheet Pan Setup for Roast Celeriac
Use a sharp chef’s knife, sturdy peeler, large cutting board, and a heavy sheet pan. Parchment makes cleanup easier, but bare metal gives slightly stronger browning.
More Ways to Cook Celeriac
Peel Deeper Than You Think
Celeriac skin is thick, knobbly, and sometimes fibrous underneath. Trim off the root end, stabilize the bulb, and cut away the rough patches until the flesh is clean and pale.
Why Thick Wedges Roast Better
Thin pieces dry out before the middle gets creamy. Thick wedges give you contrast: browned flat sides, tender centers, and enough structure to serve as a side or bowl ingredient.
Caramelized Edges Without a Dry Center
High heat gives browning, but space gives browning without steaming. If the tray is crowded, use two pans. Flip once when the bottoms are golden, then finish until a knife slides in easily.
Roast Celeriac Recipe

This serves 4 as a side.
Ingredients
- 1 large celeriac, about 1 3/4 to 2 1/4 lb (800 g to 1 kg) before peeling
- 2 tablespoons (30 ml) olive oil
- 1 teaspoon (5 g) kosher salt
- 1/2 teaspoon black pepper
- 2 garlic cloves, lightly crushed
- 3 thyme sprigs, or 1/2 teaspoon dried thyme
- 1 tablespoon (15 ml) lemon juice for serving
- Optional: chopped parsley or grated Parmesan
Instructions
- Heat the oven to 425°F (220°C).
- Peel the celeriac deeply and cut into thick wedges.
- Toss with olive oil, salt, pepper, garlic, and thyme.
- Spread on a sheet pan with space between pieces.
- Roast 20 minutes, then flip the wedges.
- Roast 15 to 20 minutes more, until browned and tender in the center.
- Finish with lemon juice and parsley or Parmesan if using.
Notes
- Use two sheet pans if the wedges are crowded.
- If the wedges brown too fast, lower the oven to 400°F (200°C) for the final 10 minutes.
- Leftovers are excellent in soup or grain bowls.
How to Serve Roast Celeriac
Serve with roast chicken, steak, lentils, yogurt sauce, tahini sauce, chimichurri, or a fried egg. It also works in grain bowls with greens and something acidic.
Storage and Leftovers
Store for up to 4 days. Reheat in a hot oven or air fryer. Leftovers can be blended into soup with stock, garlic, and a splash of cream.
How to Brown Celeriac Without Drying It Out
Roast celeriac works best when the pieces are thick enough to stay creamy inside. Thin slices brown quickly, but they can dry out before the center turns soft. Wedges give you a better contrast between caramelized edges and tender middles.
Use enough oil to lightly coat every surface, then spread the pieces out with space between them. If the tray is crowded, the celeriac releases steam and the edges stay pale.
If the wedges are tender but not browned, move the tray higher in the oven for the last few minutes. If they are browning too fast, lower the heat slightly and give the centers more time.
What to Serve With Roast Celeriac
Roast celeriac works anywhere you would normally serve roasted potatoes, parsnips, or cauliflower, but its flavor is a little deeper and nuttier. It is especially good beside roast chicken, pan-fried fish, lentils, white beans, or a simple mushroom sauce.
For a vegetarian meal, serve the wedges over yogurt sauce, tahini, or a garlicky bean puree. Add something sharp on the side, like pickled onions, lemony greens, or a mustardy salad, so the creamy center does not feel too heavy.
Leftover roast celeriac is useful too. Chop it into grain bowls, fold it into warm salads, or pan-fry the pieces the next day until the edges crisp again. If you want a soup base, blend leftovers with stock and a splash of cream or coconut milk.
Frequently Asked Questions
Do you peel celeriac before roasting?
Yes. Peel deeply to remove the rough skin and fibrous patches.
What temperature is best for roasting celeriac?
425°F (220°C) gives good browning while keeping the center creamy.
How long does celeriac take to roast?
Thick wedges usually take 35 to 40 minutes.
Why is my roast celeriac not browning?
The tray may be crowded, or the pieces may be too wet. Give the wedges space and roast at high heat.
Can I roast celeriac whole?
Yes, but that is a different method and takes much longer. Wedges are faster and brown better.
What does roasted celeriac taste like?
It tastes earthy, lightly sweet, and nutty, with a texture somewhere between roasted potato and celery root puree.
Key Takeaways
- Peel celeriac deeply before roasting.
- Cut thick wedges for creamy centers.
- Roast at 425°F (220°C).
- Leave space on the tray so edges caramelize.
- Use leftovers for soup or grain bowls.
Wrapping Up
Roast celeriac is ready when the edges are browned and the center gives easily to a knife. Do not judge it by color alone; the best pieces are dark on the cut sides and soft all the way through.
