Ingredients:
- 1.5 lbs top sirloin steak, sliced across the grain into 1/2-inch strips
- 1 tsp kosher salt
- 1/2 tsp cracked black pepper
- 1 tbsp neutral oil
- 1 lb cremini mushrooms, sliced thick
- 2 large shallots, finely minced
- 3 cloves garlic, minced
- 2 tbsp unsalted butter
- 1 tbsp all-purpose flour
- 1 cup high-quality beef stock
- 1/2 cup full-fat sour cream
- 1 tbsp Dijon mustard
- 1 tsp Worcestershire sauce
- 12 oz wide egg noodles
- 2 tbsp fresh parsley, chopped
- 1 tbsp fresh chives, minced
Instructions:
- Pat the beef strips bone-dry with paper towels. Season aggressively with salt and pepper.
- Heat a large skillet over high heat with neutral oil. Sear the beef in batches for 2 minutes until a dark crust forms. Remove beef from pan and set aside.
- In the same skillet, melt butter. Add sliced mushrooms and sauté until browned and moisture has evaporated. Stir in minced shallots and garlic, cooking for 1-2 minutes until softened.
- Sprinkle flour over the mushrooms and stir for 1 minute. Gradually whisk in the beef stock and Worcestershire sauce, scraping the bottom of the pan to release the fond. Simmer until thickened.
- In a small bowl, whisk sour cream and Dijon mustard. Reduce heat to low and stir the mixture into the sauce. Return beef and any accumulated juices to the pan.
- Boil egg noodles according to package directions. Serve the beef and gravy over the noodles, garnished with fresh parsley and chives.
