Start by preheating the oven to 400F/200C and getting a baking sheet handy.
Prepare the celeriac by peeling off the rough skin. It may be easier to use a knife than a vegetable peeler the celeriac, then chop it into 1-inch pieces.

Spread into a single layer on a sheet pan and roast in the oven for 20 minutes or until golden on the outside and soft and cooked inside. Serve hot.
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.

Many people say that it tastes like a mild version of celery but with a more nutty and earthy flavor.
You can, but the taste may be slightly bitter. To eat it raw, it’s best when peeled, then shaved into smaller pieces and put into salads or slaw recipes.
Yes. The outer peel is bitter, the folds can hold dirt and it can be tough to digest, even if it's cooked. For best results use a sharp knife or vegetable peeler to remove the outer layer safely before cooking. Cut the bottom so it sits flat and doesn't roll around, then carefully remove the knobbly peel.
