Start by preheating the oven to 400F/200C and getting a baking sheet handy.

Tips
The skin on a celeriac root is tough and bumpy with many ridges. Therefore, it may be easier to carefully remove the skin with a sharp paring knife instead of a vegetable peeler.
When laying out the celeriac on the baking sheet, make sure you do so in a single layer. If they are too close together, they will partially steam instead of roast which will change the texture.
When preparing celeriac, chop all the pieces roughly the same size so they cook evenly and all at once.
Do not use fresh herbs in this recipe before roasting as they can burn in the 400F heat and cause them to become bitter.
