Preheat your oven to 425°F and prepare a baking sheet by lining it with parchment paper or foil for easy cleanup.

In a large mixing bowl, combine the melted salted butter, brown sugar, cinnamon, and salt. Mix thoroughly until the ingredients form a smooth coating.

Using a paper towel, gently pat the baby carrots dry to ensure the seasoning adheres well. Add the carrots to the bowl and toss them until evenly coated with the mixture.

Spread the carrots out on the prepared baking sheet in a single layer and roast for 20–25 minutes, turning them halfway through the cooking time. To test for doneness, pierce a carrot with a fork; it should be tender.

Once roasted, transfer the carrots to a serving plate. Serve warm and enjoy!
