Preheat the oven to 425º F.
Peel the carrots, give them a good rinse under cool water, then pat them dry. Slice them into 1/2-inch thick diagonal pieces.
Put the carrots into a large mixing bowl and drizzle them with olive oil. Sprinkle with salt and pepper, then toss to coat.
Dump the carrots onto a baking sheet and spread them out evenly so they aren't crowded. Roast for 25-30 minutes, or until the carrots are golden and tender, shaking and stirring them halfway through cooking time.
While the carrots are roasting, mix the honey and red pepper flakes in a small bowl and set it aside.
Once the carrots are cooked, transfer them back to the mixing bowl. Drizzle the hot honey on top and toss to evenly coat the carrots, then serve!
