Mashed Potato Casserole

I stole this recipe for Mashed Potato Casserole from houseofyumm.com. This potato casserole is a perfect side for a summer barbecue because it can be prepped the day before. First potatoes are peeled and chopped then boiled. After cooling the potatoes are mashed and mixed with butter, sour cream, milk, garlic powder and salt. Then shredded cheddar cheese is mixed in before spreading the mixture into a baking dish. Next a mixture of butter and panko bread crumbs is sprinkled on top with more shredded cheese. The casserole is baked until the cheese is melted. Any potatoes you prefer can be used in this recipe.

The ingredients for this recipe are: 3 lbs russet potatoes, 7 tbsp butter, ¾ cup sour cream, ¼ cup milk, ½ tsp garlic powder, ¾ tsp salt, 1½ cups cheddar cheese, ¼ cup panko, 1 tbsp butter and 2 tbsp chives

Peel and chop the potatoes. Then add to a large pot. Cover with water and heat over high heat, boil the potatoes in the water about 20 minutes or until softened.

Drain the potatoes and add to a large mixing bowl.

Add the butter, sour cream, milk, garlic powder and salt.

Mix with a potato masher or use an electric mixer. Next add 1 cup shredded cheese and stir to combine.

Spray a 2 quart baking dish with cooking spray. Spoon the potato mixture into the dish.

Then in a small saucepan add the tablespoon of butter and panko bread crumbs. Cook over medium heat until just toasted. Sprinkle on top of the potatoes with ½ cup cheddar cheese.

Bake uncovered in a 350 F oven for about 15 minutes until the cheese is melted.

Serve warm and enjoy!
