What to do when you have a large amount of Prime Rib leftover? Make French Dip sammies of course! This is a quick and easy crowd pleaser that is suitable for a hearty lunch or dinner. If you don’t have prime rib in the house, you can always buy deli roast beef but it prime rib would be my first choice!


This is one of those dishes that will make you look like a Culinary Goddess but is easy-peasy to make.

  • One baguette of French Bread or Sourdough, sliced length-wise
  • 1 lb prime rib or roast beef, thinly sliced
  • 810 slices provolone cheese
  • 32 oz (1 qt) beef broth

Secretariat Dipping sauce (optional) or horseradish mayo (mayo with a little horseradish mixed in)


Preheat the oven to 350 degrees. Slice the baguette in half lengthwise. Place the baguette on a cookie sheet lined with foil. Layer both sides with the provolone cheese. To the side of the baguette on the cookie sheet, put the roast beef on the foil so it can heat at the same time. Bake about 10 minutes or until the cheese is melted and bubbly.

Let the baguette/cheese and meat roast in the oven until the cheese is melted. Meanwhile, heat the beef stock on the stove until hot.

Pull the baguette out of the oven and place on a cutting board. Place the meat evenly on the bottom baguette and place the other baguette on top. Slice into 3″ sandwiches and serve with a small single serving of beef broth per person. Serve with secretariat sauce or horseradish mayo.

Dinner is served and it took you less than 15 minutes!
