Wondering what to do with your leftover roast beef from the holidays? Well look no further– this by far the easiest and most delicious way to repurpose your leftovers into a delicious lunch or dinner over the next few days. You may even find yourself making extra next year just so you have enough leftovers for lots of french dip sandwiches. At least that’s my plan for next year 😉
Leftover roast beef, or deli sliced roast beef
2 tablespoons butter
1 shallot, chopped
1 tablespoon all-purpose flour
2 cans beef broth
coarse salt and pepper
4 torpedo sandwich rolls, split
mozzarella cheese, to top
In a large, shallow skillet over moderate heat, melt butter. Add shallots to butter and saute for about 2 minutes. Add flour to butter and shallot and cook a minute longer. Whisk in beef stock in a slow stream. Bring sauce to a bubble and allow to simmer over low heat until ready to serve sandwiches.
Pile meat loosely across your cutting board or a large work surface. Season meat with grill seasoning or salt and black pepper.
Toast sandwich rolls in oven, using a pair of kitchen tongs, dip meat in au jus sauce and pile into rolls. Top with mozzarella cheese and toast sandwiches for another 2 minutes, until cheese is melted. Set ramekins or cups with extra dipping sauce along side the sandwiches.
