Peel the rutabaga. It has somewhat thick skin and the bigger the rutabaga is, it gets even worse.
Cut the rutabaga as we would do it with french fries about half inch / 1cm wide wedges. Try to cut them evenly otherwise the small pieces will get burnt while the big chunks hasn't even warmed up.
Rub them with cooking oil and salt. Add optional spices and herbs if desired.
Place them onto a rack, parchment paper or baking sheet.
Put them into a 400°F / 200°C oven for 30 - 40 minutes.
