¼cupchopped fresh chives or green onionsoptional, for garnish
Instructions
Preheat your oven to 350°F (175°C) and grease a large baking dish (9x13-inch or similar size).
In a large bowl, combine the mashed potatoes and melted butter.
Stir in the sour cream. If the consistency seems too thick, you can stir in milk a little at a time until your desired consistency is reached.
Season the mashed potatoes with garlic powder, salt, and pepper to taste. Adjust the seasoning according to your preference. Fold in 1 cup of shredded cheddar cheese until it's evenly distributed throughout the mixture.
Spread the creamy mashed potatoes evenly in the greased baking dish. Sprinkle the remaining ½ cup of shredded cheddar cheese over the top of the mashed potatoes.
Place the casserole in the preheated oven and bake for about 20-25 minutes, or until the cheese is melted and bubbly and the edges of the casserole are slightly golden.
Remove the casserole from the oven and let it rest for a few minutes. Garnish with chopped chives or green onions, if desired.
Notes
Plan to use about 2 medium potatoes for 1 cup of mashed.
If you don't already have mashed potatoes to use - you can easily make some by adding 20 medium peeled potatoes to a large stock pot of cold water. Add in 3-5 peeled cloves of garlic as well. Make sure the water is at least an inch above the potatoes in the pot. Bring it to a boil over high heat. Boil on medium-high heat for about 12-15 minutes or until a fork can easily be inserted into a potato. Drain well and mash.
