Lorraine's Memere's Shepherd's Pie

Method

1. Preheat the oven to 400°F. Spray the bottom of a casserole dish with nonstick cooking spray.
2. Brown and drain the ground beef. Pour it into the casserole dish and spread it out evenly across the bottom. Salt and pepper to taste.
3. Whisk the cornstarch with the beef broth until there are no lumps. Pour this evenly over the ground beef to make a thick gravy.
4. Pour the vegetables over the ground beef and spread them out evenly.
5. Top the vegetables with mashed potatoes — either ones you made from scratch or the kind that come in a tub, already prepared. Spread them out evenly over the top.
6. Cover with foil and bake for 20-25 minutes. If you want the potatoes to be brown on top, you may leave them uncovered.
7. Remove the foil cover and sprinkle the shredded cheese over the top of the potatoes. Return to the oven and bake for another 5-10 minutes, until the cheese has melted. Serve hot.
