restaurantInstructions
Season the Beef
Pat the beef dry using paper towels and season with salt and black pepper. Toss lightly with the flour until each strip is evenly coated. This light coating helps develop a flavorful crust while gently thickening the finished sauce.
Dry beef sears much better than wet beef, producing richer caramelization instead of steaming.
Sear the Beef
Heat the olive oil in a large skillet over high heat. Working in batches, sear the beef for about 1 minute per side until browned but not fully cooked. Transfer each batch to a plate and avoid overcrowding the pan, which would lower the temperature and prevent proper browning.
Cook the Vegetables
Reduce the heat to medium and melt the butter in the same skillet. Add the onions and cook for about 6 minutes until softened and lightly caramelized. Stir in the mushrooms and cook another 8 minutes until they release their moisture and become golden. Add the garlic and thyme during the final minute of cooking.
Build the Sauce
Pour in the beef broth while scraping up all the flavorful browned bits from the bottom of the pan. Stir in the Dijon mustard and Worcestershire sauce, then bring the mixture to a gentle simmer for 5 to 7 minutes until slightly reduced.
Those browned bits left in the pan contain concentrated flavor that gives the sauce incredible depth.
Cook the Noodles
While the sauce simmers, bring a large pot of salted water to a boil. Cook the egg noodles until al dente according to the package directions, then drain and lightly toss with a small amount of butter to prevent sticking.
Finish the Beef
Return the seared beef and any accumulated juices to the skillet. Simmer gently for 2 to 3 minutes until the beef is just cooked through. Avoid prolonged cooking, which can make the beef tough.
Add the Sour Cream
Reduce the heat to low. Stir a few spoonfuls of the hot sauce into the sour cream to temper it, then slowly mix the tempered sour cream back into the skillet. Stir gently until the sauce becomes smooth, creamy, and fully combined.
Never allow the sauce to boil after adding sour cream, as high heat can cause it to separate.
Taste and Adjust
Taste the finished Stroganoff and adjust with additional salt, black pepper, or Dijon mustard if desired. If the sauce becomes too thick, stir in a splash of warm beef broth until it reaches the perfect consistency.
Plate and Garnish
Divide the buttered egg noodles among serving plates. Spoon the creamy beef Stroganoff generously over the noodles and garnish with freshly chopped parsley and a light sprinkle of cracked black pepper.
Serve on warm plates to keep the creamy sauce silky and hot throughout the meal.
Store and Reheat
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently over low heat, adding a splash of beef broth if necessary to loosen the sauce. Avoid boiling during reheating to preserve the smooth texture of the sour cream sauce.
Fresh parsley added after reheating restores brightness and gives leftovers a freshly made appearance.
