Peel the carrots, cut off the ends, and cut into slices. Steam for about 20 minutes or until soft (you can use a steamer basket or just a colander that you will cover with a well-fitted lid).
Drain the carrots and transfer to a large bowl. Add all the other ingredients.
Puree the carrots with a mixer/food processor until smooth. Season to taste with salt and pepper.
Transfer to a bowl and smooth out the surface with the back of a spoon.
Make brown butter: add 2 tablespoons of butter to a small pot and cook over medium heat for a couple minutes until it's melted, light brown in color, and smells nutty. Spoon it over mashed carrots.
Sprinkle lightly with chopped parsley and parmesan cheese.
Enjoy!
