Recipe Information
Ingredients
- 4 pounds Russet potatoes
- 2 teaspoons Salt
- 6 tablespoons Unsalted butter
- 8 ounces Cream cheese, softened
- 1 cup Sour cream
- 0.5 cups Milk
- 1 cup Shredded cheddar cheese
- 1 cup Shredded mozzarella cheese
- 0.5 cups Grated Parmesan cheese
- 0.5 teaspoons Ground black pepper
- 0.5 teaspoons Garlic powder
- 2 tablespoons Chopped fresh parsley (optional, for garnish)
- 1 spray Non-stick cooking spray
Instructions
Peel and cut the potatoes into large chunks. Place them in a large pot and cover with cold water. Add 1 teaspoon of salt to the water.
Bring the pot to a boil over medium-high heat, then reduce the heat and simmer for 15-20 minutes, or until the potatoes are fork-tender.
Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with non-stick cooking spray.
Drain the potatoes and return them to the pot. Mash the potatoes until smooth using a potato masher, or pass them through a ricer for extra creaminess.
Add the butter, cream cheese, sour cream, and milk to the mashed potatoes. Stir until fully combined and creamy.
Mix in 1/2 cup of the shredded cheddar cheese, 1/2 cup of the shredded mozzarella cheese, and 1/4 cup of the grated Parmesan cheese. Season with the remaining 1 teaspoon of salt, black pepper, and garlic powder.
Transfer the mashed potato mixture to the prepared baking dish, spreading it out evenly.
Sprinkle the remaining cheddar, mozzarella, and Parmesan cheeses evenly over the top of the casserole.
Bake in the preheated oven for 20-25 minutes, or until the casserole is heated through and the cheese on top is melted and bubbly.
If desired, turn on the broiler for 2-3 minutes to achieve a golden-brown top. Watch closely to avoid burning.
Remove the casserole from the oven and let it sit for 5 minutes before serving.
Garnish with chopped fresh parsley, if desired, before serving.
