Preheat oven to 350°F. Butter bottom and sides of a 13x9- inch baking dish with 1 Tbsp butter or spray with nonstick cooking spray. Set aside.
In a large pot, cover cubed potatoes with cold water. Season water with 1 tsp salt. Bring to a boil cooking over medium-high heat until fork-tender, about 12-15 minutes. Drain well.
Return potatoes to pot. Using an electric mixer whip in 4 Tbsp butter, half and half, 1 tsp salt, garlic powder, onion powder, pepper and nutmeg. Whip for 2 minutes or until creamy and fully combined. Add additional half and half as needed while whipping. Taste and adjust the salt to your taste.
By hand, mix in 1½ cups shredded sharp cheddar cheese, garlic-herb cheese spread, and chives. Stir until evenly distributed.
Pour potato mixture into the prepared dish and spread evenly. Sprinkle the top with remaining shredded cheddar cheese. Bake immediately or cover with plastic wrap and refrigerate for several hours or overnight.
If chilled, remove from refrigerator at least 30 minutes before baking. Dot the top with the remaining 1 Tbsp of butter (more if desired) then place into the preheated oven.
Bake for 40-45 minutes or until the top is golden brown and the potatoes are heated through. Let stand 5 minutes, then serve.
