Creating Gordon Ramsay Beef Stroganoff can be straightforward if you follow these simple steps:

1. Prepare Ingredients: Begin by slicing the beef into thin strips and chopping the onions and garlic.
2. Heat Oil: In a large skillet, heat olive oil over medium-high heat.
3. Sear Beef: Add the beef strips to the skillet, seasoning with salt and pepper. Sear until browned, approximately 2-3 minutes. Remove the beef from the skillet and set aside.
4. Sauté Onions and Mushrooms: In the same skillet, add butter. Once melted, add the onions and garlic, cooking until softened. Add the mushrooms and cook until they release their moisture.
5. Make a Roux: Sprinkle flour over the cooked onions and mushrooms, stirring to combine. Cook for an additional minute.
6. Add Liquid: Gradually pour in the beef broth while stirring to avoid lumps. Bring the mixture to a simmer.
7. Incorporate Beef: Return the seared beef to the skillet, along with the Dijon mustard. Stir to combine and simmer for about 5 minutes.
8. Add Sour Cream: Reduce heat to low, then stir in the sour cream. Mix until well combined and heated, ensuring the sauce doesn’t boil.
9. Adjust Seasoning: Taste the sauce and adjust seasonings with salt and pepper as needed.
10. Serve: Spoon the Stroganoff over cooked egg noodles or rice. Garnish with fresh parsley for color.
