Preheat the oven to 425°F and line a large baking sheet with parchment paper.
Wash and peel carrots. If you have some large carrots in the bunch, cut them in half, lengthwise.
Place carrots in a baking sheet.
Whisk together olive oil, honey, orange zest, salt, and pepper. Pour the mixture over carrots and then mix the carrots to coat them evenly.
Spread carrots in one even layer on the baking sheet and bake until fork tender, 15-20 minutes.
Notes
Storing: Store any leftover roasted carrots in the refrigerator, in an airtight container, for up to 4 days.
To reheat them, I recommend doing it on the stove. Preheat a skillet over medium heat and let them reheat until warmed through. You could also reheat them in the microwave in 30 second increments until they're as warm as you'd like them to be.
