Heat a large skillet over medium high heat. Add one pound of ground beef and a chopped onion. Season with salt, pepper, dry mustard, paprika, garlic powder, Italian seasoning, and onion powder. Once beef is cooked drain any extra grease.
Add 1 tbsp of minced garlic and 2 tbsp of Worcestershire sauce. Stir everything together well. Add 3 tbsp of butter to the skillet. Once the butter is melted add 3 tbsp of flour. Stir together and let cook for at least one minute.
Next, add a 12 oz bag of egg noodles with 3 1/2 cups of beef broth and stir well.
Once the whole skillet is bubbling, cover with a lid and turn the heat down to medium-low. Let cook for about 10 minutes (stirring once half way through cooking) or until the egg noodles are tender.
Once the egg noodles are soft, stir in your sour cream. Start with about 1/2 cup and add up to a cup to taste! Stir the sour cream into the beef stroganoff. Top with dried or fresh parsley and serve!
