Prepare the Potatoes: Begin by peeling and chopping your russet potatoes into even chunks, about 1-2 inches in size. This ensures they cook evenly.
Boil the Potatoes: In a large pot, add the chopped potatoes and cover them with cold, salted water. Bring the water to a boil over high heat. Once boiling, reduce the heat and simmer for about 15-20 minutes or until the potatoes are fork-tender.
Drain and Return: Drain the potatoes in a colander and return them to the pot. Let them steam for a couple of minutes to evaporate excess moisture—this helps keep the potatoes fluffy.
Mash the Potatoes: Using a potato masher or a ricer, mash the potatoes until smooth. Avoid over-mashing to prevent them from becoming gluey.
Add Butter and Cream: Stir in the softened butter until fully melted. Gradually add the warmed heavy cream, mixing until you reach your desired consistency. Season with salt and black pepper to taste.
Serve and Enjoy: Serve your buttery fluffy mashed potatoes warm, garnished with fresh herbs or a drizzle of olive oil for extra flavor.
