Instructions
Slice the beef into thin 1/4-inch strips against the grain and season generously with salt and pepper. Slice the mushrooms, onion, and mince the garlic; set the sour cream out to reach room temperature.
Bring a large pot of salted water to a boil, add the egg noodles, and cook according to package directions (7–9 minutes) until just tender. Reserve 1/4 cup of pasta water, then drain and toss noodles with a drizzle of olive oil to prevent sticking.
Heat olive oil in a large skillet over high heat until shimmering, then sear the beef strips in a single layer (in batches if needed) for 1–1.5 minutes per side until golden brown. Remove beef to a plate and tent with foil.
In the same skillet over medium-high heat, melt the butter and cook the onions for 3–4 minutes until softened, then add mushrooms and cook undisturbed for 2 minutes before stirring, until golden. Add garlic and stir for 30–45 seconds until fragrant.
Sprinkle flour over the mushroom mixture and stir well; cook for 1 minute. Slowly pour in the beef broth while stirring, then add the Dijon mustard and Worcestershire sauce and simmer for 3–4 minutes until the sauce thickens.
Reduce heat to low and stir in the room-temperature sour cream one spoonful at a time until fully incorporated and the sauce is smooth. Season with salt and pepper to taste.
Add the seared beef and any resting juices back into the skillet and gently fold into the sauce. Simmer on low for 2–3 minutes until the beef is cooked through — do not let the sauce boil.
Divide the egg noodles into bowls or plates, spoon the beef stroganoff generously over the top, and garnish with freshly chopped parsley. Serve immediately.
Notes
Always slice the beef against the grain into thin strips — this shortens the muscle fibers and keeps the meat tender, not chewy.
Work in two batches when searing the beef so the pan stays very hot. Crowding the pan causes the beef to steam instead of brown.
Sour cream must be at room temperature before adding it to the sauce. Cold sour cream added to a hot pan is the number one cause of a curdled, grainy sauce.
Never let the sauce boil after the sour cream has been added — keep the heat on low to maintain a smooth, creamy texture.
For a gluten-free version, replace the all-purpose flour with a gluten-free flour blend or cornstarch, use gluten-free egg noodles, and verify your Worcestershire sauce is gluten-free certified.
Full-fat Greek yogurt can replace sour cream for a slightly lighter sauce with a similar tang — use the same low-heat method to prevent curdling.
To make ahead, prepare the sauce and beef up to 2 days in advance and refrigerate. Reheat gently over low heat with a splash of beef broth and cook fresh noodles when ready to serve.
Freeze the sauce and beef (without noodles) for up to 2 months. Stir well during reheating to bring the sauce back together after freezing.
For extra depth of flavor, deglaze the pan with a splash of dry white wine or brandy after searing the beef before adding the broth.
Serve over creamy mashed potatoes or steamed white rice instead of egg noodles for an equally satisfying variation.
