We used a marbled, tender piece of ribeye as the star of this comfort food classic. Two kinds of mushrooms are cooked until crispy to add an extra element of flavor. The whole dish is brought together with a rich, tangy sauce made with sour cream and Dijon and served over egg noodles.
For superior flavor and texture, sear the beef in batches if your skillet isn't large enough to prevent overcrowding; this ensures a deep, golden crust rather than steaming. When cooking the mushrooms, allow them to crisp up properly to develop rich umami and texture. Deglazing the pan after each cooking stage is crucial to incorporate all the flavorful fond into your sauce. To prevent the sour cream from curdling, ensure it's at room temperature before adding, and avoid boiling the sauce vigorously once it's incorporated. Serve immediately for best results, garnished generously with fresh herbs.
