Arrange an oven rack to the bottom third of the oven. Preheat oven to 375ºF (190ºC).
Pour melted butter in an 11X7 inch baking dish. Sprinkle cinnamon, allspice, nutmeg, salt and pepper over butter and mix together with a fork.
Add carrots and toss to coat evenly.
Sprinkle brown sugar in an even layer over carrots.
Cover baking dish with foil and bake until carrots are tender, 20-25 minutes, stirring halfway through. Remove foil, stir carrots, drizzle with honey, and sprinkle with fresh thyme leaves. Serve.
Notes
Switch Up The Carrots: You can use whole carrots and slice them into coins or use whole baby carrots.
