1 lb. ground beef
1/4 tsp. red pepper flakes
1/4 cup chopped onion
1 cup sliced mushrooms
2 tbsp. Worcestershire sauce
8 medium red potatoes
4 tbsp. butter
1/2 cup half-and-half (or heavy cream)
1/4 cup sour cream (or cream fresh if you have it)
Salt and pepper
2 cups shredded cheddar cheese (or whatever you have on hand)
Preheat oven 375 degrees.
Brown beef in a large skillet. Drain off excess grease. Add Worcestershire sauce, red pepper flakes, onions and mushroom and cook until just tender. Set aside.
Meanwhile, heat a large pot of salted water to boiling. Add potatoes and garlic; cook until fork tender. Drain and return to pot. Add butter, cream, and sour cream and mash until smooth. Season with salt and pepper.
In a 13 x 9 inch baking dish spread the hamburger and mushroom mixture. Sprinkle with a layer of cheese. Spoon mashed potatoes over top of the cheese mixture.
Bake for 30 minutes or until mashed potatoes begin to brown. Serve with ketchup or gravy.
