I recommend roasting carrots and parsnips covered for half the time and uncovered for half the time. This method allows the veg to soften for the first half, then caramelize.   Make these yummy protein-forward mains alongside the roasted veg for a filling meal: The BEST Crispy Bone-in Chicken Thighs, The BEST Crispy Tofu (Pan-Fried), or Slow Cooker Gammon Joint.
