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

1. Prepare the Ingredients: Start by gathering and measuring all your ingredients. Thinly slice the beef and chop the onion and garlic.
2. Sauté the Beef: In a large skillet, heat 1 tablespoon of olive oil over medium-high heat. Add the sliced beef and sear until browned. This allows for a rich flavor. Remove beef and set aside.
3. Cook the Onions and Mushrooms: In the same skillet, add another tablespoon of olive oil. Add the chopped onions and sliced mushrooms, cooking until they soften, about 5 minutes. Stir frequently to prevent burning.
4. Add Garlic and Mustard: Toss in the minced garlic and Dijon mustard. Sauté for another minute until fragrant.
5. Deglaze the Pan: Pour in the beef broth, scraping the bottom of the pan to release any flavorful bits. Bring to a gentle simmer.
6. Incorporate the Beef: Return the browned beef to the skillet. Stir to mix everything well.
7. Thicken the Sauce: If you prefer a thicker consistency, sprinkle in flour and stir until combined. Allow it to simmer for 2-3 minutes to thicken.
8. Add Sour Cream: Reduce the heat to low and gently stir in the sour cream until creamy and smooth. Avoid boiling to prevent curdling.
9. Season: Taste and adjust seasoning with salt and pepper as needed.
10. Prepare the Noodles or Rice: While you’re finishing the sauce, cook the egg noodles or rice according to the package instructions.
11. Serve: Dish out the beef stroganoff over the noodles or rice, garnishing with freshly chopped parsley for a burst of color.

By following these straightforward steps, you’ll have a delicious and comforting meal ready to enjoy in no time!
