Preheat oven to Place a sheet of aluminum foil on a baking sheet (standard cookie sheet). Slice carrots. Place carrots on prepared pan. Drizzle olive oil and maple syrup over the carrots. Top with thyme, salt and pepper. Lightly toss carrots until carrots are coated in oil and syrup and herbs and spices are well distributed. Place in oven for 25 minutes. Turn carrots halfway through for even cooking. Serve immediately. Garnish with fresh herbs if desired.
