@Kevin the key was to par boil them for 5 mins before roasting. Perfectly al dente
@tremblay this I have not done! Shall try
@Kevin as a rule of thumb I check serious eats before I make anything I have not "mastered" https://www.seriouseats.com/how-to-roast-carrots
How to Roast Carrots and Parsnips
