5 pounds Yukon gold russet potatoes, peeled and cut into quarters
1 tablespoon kosher salt
8 ounces cream cheese, softened to room temeprature
½ cup sour cream, warmed
½ cup half and half, warmed
4 tablespoons salted sweet cream butter, melted
2 to 3 tablespoons salted sweet cream butter, softened (for buttering the baking dish)
2 teaspoons onion powder
1 teaspoon kosher salt
½ teaspoon fresh cracked black pepper
1 teaspoon dried parsley
4 cups fresh shredded Colby jack cheddar cheese, divided into 2 cups and 2 cups
1 tablespoon chopped fresh chives, optional garnish

Add the prepared potatoes and 1 tablespoon of kosher salt to a 5 to 6-quart stock pot or saucepan over medium-high heat. Cook for 20 to 25 minutes until the potatoes are fork-tender. Drain the potatoes and set them aside.
Add the softened cream cheese, sour cream, half and half, and butter to the same pot used to boil the potatoes.
Preheat the oven to 375°F. Generously butter a 9x13 baking dish with the softened butter. Pay close attention to the corners and bottom of the baking dish.
Add the drained cooked potatoes over the ingredients in the pot.
Sprinkle the onion powder, kosher salt, pepper, and dried parsley over the potatoes.
Use a potato masher to mash all the ingredients together. Continue mashing until smooth and very few lumps of cooked potato remain.
Stir in 2 cups of the shredded Colby jack cheese.
Evenly spread the cheesy mashed potatoes in the prepared baking dish. Cover tightly with aluminum foil and bake covered for 30 minutes.
Remove the baking dish from the oven. Remove the foil and sprinkle the remaining 2 cups of cheese over the potatoes. Bake for another 10 minutes or until the cheese is melted. Remove from the oven and allow the dish to rest for 5 minutes before serving. (Remember, this will be incredibly hot, so be careful)

The purpose of warming the cream and sour cream is so that you don’t bring down the temperature of the potatoes when mixing them in.
You can adjust your salt depending on your personal preference. Adding another ½ teaspoon would be fine as there is a large number of potatoes, but if you prefer less salt, leave the quantity as is.
Oven temperatures vary and may need to be recalibrated periodically to ensure they are accurate. Make sure to keep a close eye on your cheesy mashed potatoes casserole as the suggested baking time approaches.
