Peel the carrots, then cut them diagonally into 1/4-inch slices.
Place the carrots, water, salt, and pepper in a large skillet or saute pan set over medium-high heat. Bring to a boil, then reduce to medium-low, cover, and cook for 7-8 minutes until the carrots are just cooked through.
Add the butter and oil and saute for 1 minute, until the water evaporates and the carrots are coated.
Remove from heat and toss with the parsley. Season with salt and pepper to taste before serving.
