Roasted vegetables

Step 1 of 4

Cut for time, not for looks

Heat the oven to 400°F. Cut the carrots and parsnips into chunky pieces and the zucchini noticeably larger, because they cook fastest. Keep the onion wedges attached at the root so they hold together.

Matching sizes is the wrong instinct. Match how long each vegetable takes, and cut the quick ones bigger.
