Instructions

Peel and cut potatoes into quarters. Place potatoes in a large pot. Cover potatoes with water and add 1-1/2 tablespoons salt.

Bring potatoes to a boil over medium heat. Cover with lid slightly ajar and cook until done (about 20 minutes).

Remove the potatoes from the heat and drain off the water.

Using a potato masher, mash potatoes until all chunks have been removed.

Add butter, cream, half-and-half, mascarpone cheese, thyme and salt and pepper.

Continue to mash and stir until the potatoes are creamy. Serve while hot.
