Step-by-Step Instructions
- Begin by preheating a large frying pan over medium-high heat. Add a splash of neutral oil, ensuring the oil shimmers but doesn't smoke. Prepare your rib-eye steak by trimming and pounding it.
- Once the oil is hot, lay the rib-eye steak in the pan and sear for about 3-4 minutes on each side until browned. Remove it from the pan and set aside to rest.
- In the same pan, reduce the heat slightly and add butter. Once melted, add thinly sliced onions and cremini mushrooms, sautéing for about 5-7 minutes.
- Sprinkle flour over the sautéed mixture, stirring well to combine for about a minute. Gradually pour in beef broth, whisking to prevent lumps. Let simmer for 2-3 minutes.
- Stir in Dijon mustard and full-fat sour cream, warming gently for another 2 minutes. Avoid boiling to prevent curdling.
- Return seared rib-eye steak to the pan, tossing in the sauce for about a minute. Season with salt and pepper. Serve over egg noodles or tagliatelle, garnished with chopped chives.

Notes
For the best flavor and texture, stir in sour cream just before serving and ensure to taste and season throughout cooking.
