How to Make Au Gratin Beef Bake

In a large skillet, brown 1 lb ground beef over medium-high heat. Drain off any excess grease.
Add 1 medium onion (chopped), 2 celery stalks (chopped), and 1 green bell pepper (chopped) to the skillet. Cook until the vegetables are tender and the beef is no longer pink (about 8-10 minutes).
Preheat oven to 400°F (200°C).
In a greased 2 1/2-quart baking dish, combine the beef mixture with 2 lbs potatoes (peeled and thinly sliced), 1 packet (1 ounce) of au gratin potato sauce mix, 10.75 oz can condensed cream of mushroom soup, and 1 teaspoon Worcestershire sauce.
Stir in 1/2 cup water and 1/2 cup milk.
