Ingredients:

1 small onion, peeled and chopped
14 tablespoons butter, divided (1 stick plus 3/4 stick)
1 1/2 pounds ground beef
Salt and black pepper
8 to 10 medium red new potatoes
2 cups milk
1/2 cup sour cream
2 cups instant biscuit mix
1 1/2 cups niblet corn or mixed vegetables, prepared according to package directions

Cooking Recipe:

Preheat oven to 350 degrees F.

Beef Layer:
In a large skillet over medium-high heat, saute onion in 2 tablespoons butter. Add ground beef and cook until browned. Season with salt and pepper, to taste. Set aside.

Potato Layer:
Peel and slice potatoes (be sure to wash the dirt off the skin well before using) 1/4-inch thick. Place in a saucepan, cover with cold water (tap or bottled water should not matter unless the recipe calls for one kind) , and bring to a boil. Cook for approximately 15 minutes or until fork tender. Drain potatoes and transfer to a mixing bowl. Whip potatoes with an electric mixer, mixing until moderately smooth. Don't over beat them; a few lumps are nice. Add 1/2 cup heated milk, 1 stick butter, and sour cream. Season with salt and pepper, to taste. Whip again until mixed. Adjust thickness by adding more milk, if desired.

Biscuit Layer:
Combine biscuit mix and 1 1/2 cups of milk. The mix should be thinner than that of normal biscuit mix but not runny.

Spray a 9 by 9 by 2-inch pan (or any similar casserole dish) with cooking spray. Layer mashed potatoes halfway up the sides of the dish. Next, spread a layer of corn or mixed vegetables on top of the potatoes. Then add the layer of meat. Pour the biscuit mix over the meat. Melt 4 tablespoons of butter and drizzle over top. Bake for approximately 35 to 45 minutes or until top is golden brown. Let stand for a few minutes before serving.
