Equipment

Ingredients

2 pounds ground beef
1 10.5 ounces can french onion soup
½ medium onion sliced
1 tablespoon butter
8 ounces mushrooms sliced
1 10.5 ounces cream of mushroom soup
1 packet onion soup mix
¼ cup all purpose flour
3 tablespoons ketchup
¼ cup water
2 tablespoons Worcestershire sauce
1.5 teaspoons ground mustard
1 teaspoon salt
½ teaspoon pepper
1 14.5 ounces can french style green beans
3 cups mashed potatoes prepared

Instructions

Preheat oven to 350F. Spray a 9x13 pan with nonstick spray.
In a large skillet cook the ground beef and ⅓ can of french onion soup until the meat is no longer pink. Remove to a bowl and drain excess fat.
To the skillet add the butter. Saute the mushrooms and onions in the butter until the mushrooms are brown and the onions are tender.
Spread the ground beef in the prepared 9x13 pan.
In a medium bowl, combine the remaining ⅔ french onion soup, onion soup mix, condensed mushroom soup, ketchup, water, Worcestershire sauce, flour, salt, pepper, and mustard. Stir to mix.
Pour soup mixture over the ground beef in the 9x13 and spread into an even layer.
Top the soup mixture with the mushrooms and onions.
Drain and rinse the canned green beans.
Spread them over the mushrooms and onions.
Top with prepared mashed potatoes and spread into an even layer.
Bake at 350F for 25-30 minutes or until the casserole is bubbly and the internal temperature has reached 165F.
Remove and let set for 3-5 minutes (it will be runny a little)
Serve warm and enjoy.

Notes

If you want to brown the top just a bit more, then stick it under the broiler for the last few minutes. Keep an eye on it though so it doesn't burn the top.

To make clean up easier, then pre-coat your casserole pan with a light spray of cooking oil.

Make sure to strain the ground beef after cooking it. There is enough liquid in the dish that you don't need extra water and oil.

You can garnish the top with some chopped parsley to sprinkle some color onto it.

Let this sit a few minutes after removing from the oven. This allows everything to thicken a bit more so it is easier to serve.
