Preheat oven to 425 degrees F. Lightly coat a large, rimmed baking sheet with non-stick spray and set aside.
Combine the sliced carrots, olive oil, melted butter, honey, salt and pepper in a large bowl and stir to coat. Place carrots in an even layer on prepared baking sheet.
Roast for 20 minutes, stir and continue roasting for an additional 15 to 20 minutes, until carrots are tender and slightly caramelized. Garnish with freshly chopped parsley and enjoy!
Notes
You may also use baby carrots in place of the whole, sliced carrots.
