Instructions

Sautéing the Beef and Veggies

1. Heat the Skillet. Place a large cast‑iron or stainless skillet over medium‑high heat for 2‑3 minutes. Add 2 tablespoons olive oil and swirl until it shimmers. The hot oil creates a barrier that locks in beef juices and encourages caramelization.
2. Sear the Beef. Add the ribeye in a single layer, being careful not to overcrowd. Cook for 2‑3 minutes per side until a deep brown crust forms. Remove the meat to a plate and keep warm; it will finish cooking in the oven.
3. Sauté the Vegetables. In the same pan, add the onions, bell peppers, and mushrooms. Cook, stirring occasionally, for 5‑6 minutes until they soften and begin to caramelize. Deglaze the pan with a splash of water or broth if bits stick—those browned pieces are flavor gold.
4. Make the Creamy Sauce. Reduce heat to medium and stir in ¼ cup heavy cream, 2 tablespoons Worcestershire sauce, ½ teaspoon garlic powder, and a pinch of salt and pepper. Simmer for 2‑3 minutes, allowing the sauce to thicken slightly and coat the vegetables.
5. Combine Everything. Return the seared ribeye to the skillet, tossing to coat with the creamy mixture. Transfer the entire mixture to a 9‑x‑13‑inch casserole dish, spreading evenly.
