In a large skillet, heat the olive oil over medium-high heat. Add the sliced beef and cook until browned, about 3-4 minutes. Remove the beef from the skillet and set aside.
In the same skillet, add the chopped onion and cook until translucent, about 3 minutes. Stir in the minced garlic and sliced mushrooms, cooking until the mushrooms are tender, about 5 minutes.
Sprinkle the paprika over the mushroom mixture and stir well. Pour in the beef broth and Worcestershire sauce, bringing the mixture to a simmer. Let it cook for about 5 minutes.
Reduce the heat to low and stir in the sour cream until well combined. Return the cooked beef to the skillet, stirring to coat in the sauce. Season with salt and pepper to taste.
Meanwhile, cook the egg noodles according to package instructions. Drain and set aside.
Serve the beef stroganoff over the egg noodles, garnished with fresh parsley.
