2 lbs cooked pot roast, sliced thin across the grain
1cup caramelized onions
8 slices sourdough bread
16 slices provolone cheese
2cups beef broth (use liquid from cooking the pot roast)
1 packet onion soup mix
1/2 beef bouillon cube
Home fries for serving
Instructions
Turn on the broiler to low setting. Place the slices of bread on a parchment-lined baking sheet, pile with thinly sliced pot roast and top with two slices of provolone each.
Place under the broiler for a couple of minutes. Keep the light in the oven on to check and ensure the bread doesn’t burn.
Meanwhile, make the ‘au jus’ by adding the broth to a saucepan and turn on high heat. Whisk in the onion soup mix and crumble in the bouillon and stir until melted and combined.
Bring to a rolling boil and continue to cook until the liquid is halved.
Close the sandwiches, cut in half and serve with the au jus and home fries.
