Creating Gordon Ramsay Beef Stroganoff is a delightful journey as you follow these simple steps to achieve a restaurant-quality meal:

1. Heat the Oil: In a large skillet, heat the olive oil over medium-high heat.
2. Sauté the Beef: Add the sliced beef to the skillet and season with salt and pepper. Sauté until browned, about 3-4 minutes. Remove beef from the skillet and set aside.
3. Cook the Aromatics: In the same skillet, add the chopped onion and cook until translucent, about 3 minutes. Add the minced garlic and sauté for another minute.
4. Add the Mushrooms: Toss in the sliced mushrooms and cook for about 5-7 minutes, allowing them to brown and soften.
5. Create the Sauce: Sprinkle the flour over the mushroom and onion mixture, stirring well to combine. Gradually add the beef broth and Worcestershire sauce, stirring until the mixture thickens.
6. Incorporate the Cream: Reduce the heat to low, then stir in the sour cream and Dijon mustard. Mix well to create a creamy sauce.
7. Return the Beef: Add the sautéed beef back into the skillet, stirring to coat with the sauce. Heat through for a couple of minutes.
8. Taste and Adjust: Taste the stroganoff and adjust seasoning with more salt and pepper if needed.
9. Prepare the Noodles or Rice: As the stroganoff simmers, cook the egg noodles or rice according to package instructions.
10. Serve: Once everything is cooked, serve the stroganoff hot over the prepared egg noodles or rice, garnished with chopped parsley.

These steps will guide you to create a dish that is not only delicious but also a feast for the eyes!
