4 large russet potatoes,scrubbed clean
2 TBS butter, melted
2 cups shredded cheddar cheese, divided
4 green onions, white and green parts thinly chopped
1/2 cup sour cream
1/4 cup milk
1 tsp salt
1/2 tsp pepper
-preheat oven to 400 degrees. Pierce each potato 3-4 times with a fork and place on a cookie sheet in the oven. Bake for 30 min or until a fork can easily be inserted into potato. Remove potatoes from oven and let cool 5-10 mint.
-Carefully cut each potato inhalf lengthwise so you get 2 boat shapes from each potato. Use an oven mitt to hold potato, and scoop out the insides with a spoon, place insides in a bowl. Leave a thin lining so potato skin wont collapse.
-Use a potato masher to mash the potato insides. Stir in melted butter, 1 cup of the cheese, green onions, sour cream, milk, salt and pepper. Mix well.
-Preheat the boiler. Move the oven rack 3-4 inches from the top of oven.
-Scoop the potato filling into shells, use all the filling mounding over top. Sprinkle remaining cheese on top. Place in broiler until cheese melts and is hot and bubbly...around 5 min.
