First of all, you should remove the fats from the beef. Then, cut the beef in one-inch pieces and season it with onion powder, salt, pepper and garlic.
Then, take a bowl and mix flour, salt and pepper in it. Dredge the beef pieces in the bowl to coat them with the mixture.
Preheat a large skillet on medium heat flame on the stove and put the beef pieces in it. Add butter, garlic and onion into it and cook them well until the meat become brown.
Now, add mushrooms and cook for around half an hour. After that, you have to gradually mix flour in cold water. Add this flour mixture to the pan containing the beef and cook for around 3 to 5 minutes on medium heat. Then, pour cream and mushroom soup to the mixture.
Prepare the egg noodles in another pan by adding garlic powder and parsley. Serve beef and noodles along with salad, garlic bread and pepper.
