A delicious and hearty dish featuring tender beef steak smothered in a rich mushroom and onion sauce.
Preheat your oven to 350°F (180°C).
Preheating the oven ensures even cooking and helps achieve the desired tenderness.
In a large oven-proof skillet, melt the butter over medium-high heat and brown the beef steak on both sides.
Browning the steak locks in the juices and enhances the flavor.
Remove the steak from the skillet and set it aside.
Keep the steak covered to retain its warmth while preparing the sauce.
In the same skillet, sauté the onions and mushrooms until softened and lightly browned.
Stir occasionally to prevent sticking and ensure even cooking.
Sprinkle the flour over the vegetables and stir to coat evenly.
This step helps thicken the sauce, so ensure the flour is well incorporated.
Gradually add the beef stock and milk, stirring constantly until the sauce thickens.
Stirring constantly prevents lumps and creates a smooth sauce.
Season the sauce with salt and pepper to taste.
Taste the sauce and adjust the seasoning as needed.
Return the steak to the skillet, spooning some sauce over it.
Ensure the steak is well coated with the sauce for maximum flavor.
Cover the skillet and bake in the preheated oven for 1.5 hours until the steak is tender.
Check the steak occasionally to ensure it doesn't dry out.
Serve the steak hot, garnished with fresh herbs if desired.
