Method
- Heat a large deep pan or Dutch oven over medium-high heat. Add 2 Tbsp oil. Once the oil is very hot, add the thinly sliced beef strips in a single layer. Cook for 1 minute per side until just browned. Sear the beef in 2 batches to avoid overcrowding the pan. Remove the beef to a plate and cover to keep warm.
- Add 2 Tbsp butter, the chopped onion, and sliced mushrooms to the pan. Sauté for 6-8 minutes until the liquid has evaporated and the onions and mushrooms are soft and lightly browned.
- Add 1 minced garlic clove and sauté for 1 minute until fragrant. Add 1 Tbsp flour and sauté for another minute, stirring constantly.
- Pour in 1 cup of beef broth, scraping any bits from the bottom of the pan. Add 3/4 cup heavy whipping cream and simmer for 1 to 2 minutes until slightly thickened.
- Stir a few tablespoons of the sauce into 1/4 cup of sour cream to temper it, then add it to the pan while stirring constantly to prevent curdling.
- Stir in 1 Tbsp Worcestershire sauce, 1/2 tsp dijon mustard, and season with 1/2 tsp salt and 1/4 tsp pepper, or to taste. Continue simmering until the sauce is creamy. Add the beef with any accumulated juices back to the pan and bring just to a simmer until the beef is heated through.
