Cook the Noodles: In a large pot, bring salted water to a boil. Add egg noodles and cook according to package instructions until al dente. Drain and set aside.
Sear the Beef: In a large skillet over medium-high heat, add a tablespoon of oil. Once hot, add the beef strips in a single layer. Cook for about 3-4 minutes until browned, then remove from the skillet and set aside.
Add Garlic: Add minced garlic to the skillet and cook for an additional minute, stirring constantly to prevent burning.
Make the Sauce: Pour in the beef broth and Worcestershire sauce (if using). Bring the mixture to a simmer and let it cook for 5 minutes to reduce slightly.
Combine Everything: Lower the heat and return the browned beef to the skillet. Stir in the sour cream until fully combined, allowing everything to heat through. Season with salt and black pepper to taste.
Serve: Toss the cooked egg noodles with the beef mixture until well coated. Serve immediately, garnished with fresh parsley if desired.
Notes
For a smoother sauce, allow sour cream to come to room temperature before adding it to the hot mixture.
