Step 1

In a medium saucepan add beef broth, garlic salt, garlic powder, basil, oregano, and soy sauce. Bring contents to boil.

Step 4

Preheat oven to 350 degrees

Step 5

Meanwhile, chop the onion and add to a small saucepan along with butter or margarine. Cook on medium-high heat for about 7-10 minutes or until onions are softened.

Step 8

Once the beef broth mixture is boiling, reduce heat to medium-low and add Roast Beef to the pot. Let cook 3-5 minutes, or until roast Beef starts to brown completely. Remove from heat.

Step 11

Line a baking sheet with parchment paper and add buns. Place a couple of slices of beef on each bun, leaving behind the Au Jus on the stove, to stay warm. Top the meat with onions and sliced cheese. Place top bun back on the sandwich and bake in the oven for about 5-7 minutes.

Step 13

The bread will be toasted and the cheese will be melted. If you have not achieved this, cook another 2 minutes and check.

Step 16

Serve immediately and scoop Au Jus into Ramekins or other bowls for dunking your Italian Beef Sandwiches.
