Preheat the oven to 425 degrees F. Line a large baking sheet with parchment paper. Set aside.
Melt the butter in a large saucepan over medium-low heat. Mix in the honey, thyme, salt, and pepper. Turn off the heat.
Turn off the heat and toss the carrots in the honey mixture.
Spread the carrots out on the prepared baking sheet.
Bake for 20 to 30 minutes, flipping halfway through. (see notes)
Transfer the carrots to a serving dish (optional) and serve warm.
Notes
For a lighter roast and carrots that are still quite firm, bake them closer to 20 minutes. For a darker roast and softer carrots, bake them for closer to 30 minutes.Store leftover carrots in an airtight container in the fridge for up to 4 days.
