Instructions
Step 1: Prepare the Dish
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish. Lay the steak slices flat and, if needed, gently pound them to an even thickness for uniform cooking.
Step 2: Add Filling
Place a slice of Swiss cheese on each piece of steak, adjusting the size if necessary. Add a small amount of drained mushrooms near one edge.
Tip: Keep the filling minimal to ensure the rolls stay sealed and the cheese doesn’t leak out while baking.
Step 3: Roll the Steak
Carefully roll each piece of steak around the filling. Place them seam-side down in the baking dish, positioning them close together to help them hold their shape.
Step 4: Add Gravy
Stir the condensed gravy until smooth, then pour it evenly over the rolls.
Tip: If the gravy feels too thick, thin it with a few tablespoons of water or beef broth so it pours easily while still coating the meat.
Step 5: Bake Covered
Cover the dish tightly with foil and bake for 45–60 minutes. This helps trap moisture, allowing the beef to cook gently and become tender.
Step 6: Finish Baking
Remove the foil and bake for another 5–10 minutes to slightly thicken the gravy and develop a bit of color. Let the dish rest for about 5 minutes before serving so the filling can settle.
