Ingredients

• 4 pounds Russet potatoes
• 6 tablespoons Unsalted butter
• 1 cup Milk
• 0.5 cup Heavy cream
• 4 ounces Cream cheese, softened
• 0.5 cup Sour cream
• 1 teaspoon Garlic powder
• 2 teaspoons Salt
• 0.5 teaspoon Black pepper
• 1.5 cups Shredded cheddar cheese
• 0.5 cup Parmesan cheese, grated
• 0.5 cup Panko breadcrumbs
• 1 tablespoon Olive oil
• 2 tablespoons Fresh parsley, chopped (optional, for garnish)

Directions

Step 1

Peel and chop the potatoes into 2-inch chunks for even cooking.

Step 2

Place the potatoes in a large pot and cover with cold water. Add 1 teaspoon of salt.

Step 3

Bring the water to a boil over medium-high heat, then reduce to a simmer. Cook the potatoes for 15-20 minutes, or until fork-tender.

Step 4

While the potatoes are cooking, preheat your oven to 375°F (190°C) and grease a 9x13-inch baking dish.

Step 5

Drain the cooked potatoes and return them to the pot. Mash the potatoes until smooth using a potato masher or ricer.

Step 6

Add the butter, milk, heavy cream, cream cheese, sour cream, garlic powder, remaining 1 teaspoon of salt, and black pepper to the mashed potatoes. Stir until well combined and creamy.

Step 7

Fold in 1 cup of the shredded cheddar cheese and 1/4 cup of the Parmesan cheese.

Step 8

Spread the potato mixture evenly into the prepared baking dish.

Step 9

In a small bowl, mix the panko breadcrumbs, remaining 1/4 cup of Parmesan cheese, and olive oil. Sprinkle the mixture evenly over the potatoes.

Step 10

Top with the remaining 1/2 cup of shredded cheddar cheese.

Step 11

Bake the casserole in the preheated oven for 25-30 minutes, or until the topping is golden brown and bubbly.

Step 12

Remove from the oven and let cool for 5-10 minutes before serving.

Step 13

Garnish with chopped parsley, if desired, and serve warm.
