# Components:

02 - 1/2 tsp salt
03 - 1/2 tsp black pepper
→ Vegetables
04 - 2 tbsp unsalted butter
05 - 1 tbsp olive oil
06 - 1 medium onion, finely chopped
07 - 3 cloves garlic, minced
08 - 10 oz cremini or white mushrooms, sliced
→ Sauce
09 - 2 tbsp all-purpose flour
10 - 1 cup beef broth
11 - 1 tbsp Worcestershire sauce
12 - 1 tbsp Dijon mustard
13 - 3/4 cup sour cream
→ To Serve
14 - 10.5 oz egg noodles, cooked according to package directions
15 - 2 tbsp fresh parsley, chopped
# Method:
01 - Season the thinly sliced beef with salt and black pepper.
02 - Heat 1 tablespoon of unsalted butter and the olive oil in a large skillet set over medium-high heat. Sear the beef in batches for 1 to 2 minutes per side until just browned. Remove the beef from the skillet and set it aside on a plate.
03 - Reduce the skillet heat to medium. Add the remaining 1 tablespoon of unsalted butter. Sauté the finely chopped onion for 2 to 3 minutes until it becomes translucent. Add the minced garlic and cook for an additional 30 seconds until fragrant.
04 - Add the sliced mushrooms to the skillet. Cook for 5 to 6 minutes, stirring occasionally, until the mushrooms soften and turn golden brown.
05 - Sprinkle the all-purpose flour over the cooked vegetables and mushrooms. Stir well for 1 minute to toast the flour and eliminate its raw taste.
06 - Gradually pour in the beef broth while stirring constantly to prevent any lumps from forming. Incorporate the Worcestershire sauce and Dijon mustard.
07 - Allow the sauce to simmer for 3 to 4 minutes, stirring occasionally, until it has slightly thickened.
08 - Reduce the heat to low. Gently stir in the sour cream until the sauce is smooth and fully incorporated; avoid bringing the sauce to a boil. Return the seared beef and any accumulated juices to the skillet. Stir gently to coat the beef with the sauce and allow it to warm through for 2 to 3 minutes.
09 - Taste and adjust seasoning as needed. Serve the Beef and Mushroom Stroganoff immediately over cooked egg noodles, garnished with freshly chopped parsley.
