Creating Gordon Ramsay’s Beef Stroganoff is straightforward if you follow these clear steps:

1. Prepare the Beef: Thinly slice the beef sirloin and season with salt and pepper.
2. Heat Oil: In a large skillet, heat the olive oil over medium-high heat.
3. Cook the Beef: Add the beef to the skillet, searing it for about 2-3 minutes until browned. Remove the beef from the skillet and set aside.
4. Sauté the Onions: In the same skillet, add onions and cook for 2-3 minutes until softened.
5. Add Garlic and Mushrooms: Stir in minced garlic and sliced mushrooms, cooking for another 4-5 minutes until the mushrooms are tender.
6. Create the Sauce: Sprinkle in the flour and mix well to combine. Add the Dijon mustard and Worcestershire sauce, stirring for about a minute.
7. Add Broth: Pour in the beef broth, bringing the mixture to a gentle boil. Stir frequently until it thickens slightly.
8. Finish with Sour Cream: Lower the heat and stir in the sour cream. Return the cooked beef to the skillet, combining well until heated through.
9. Adjust Seasoning: Taste and adjust seasoning with salt and pepper as needed.
10. Serve Over Noodles or Rice: Prepare your egg noodles or rice as per package instructions and serve hot, topped with fresh parsley.

By following these straightforward steps, you can create a dish that rivals any restaurant’s Beef Stroganoff, making it a worthy addition to your culinary repertoire.
