Roasted Prime Rib Sandwich

Andy Anderson !


Here’s an excellent recipe to make for anyone that loves a good French dip sandwich. It’s actually, very simple to assemble, and if you’re using store-bought prime rib, I’ve got a down & dirty way for you to make some faux juice for the dipping sauce.

So, you ready… Let’s get into the kitchen.

How to Make Roasted Prime Rib Sandwich


  • 2Gather and prep all your ingredients.
  • 3Chef’s Note: You will need a good horseradish sauce, and some dipping sauce (au jus) to complete the sandwich. If you lack either of these I will have some additional ideas at the end of this recipe.
  • 4Add the grapeseed oil to a sauté pan over medium-high heat.
  • 5Add the onions to the pan.
  • 6Sauté the onions, for about 5 to 8 minutes, or until they begin to color.
  • 7Chef’s Note: Sometimes, about halfway thru the sauté, I’ll drop a tablespoon of butter into the pan… just to give the onions a bit more flavor.
  • 8Add the green bell pepper and mushrooms.
  • 9Continue to sauté until the onions are brown and the peppers and mushrooms are cooked through, about 5 to 8 additional minutes.
  • 10Remove from the heat and reserve.
  • 11Heat the dipping sauce in a small saucepan.
  • 12Brush the bottoms of the rolls with some horseradish sauce.
  • 13Dip the chopped beef into the hot dipping sauce, and then drain.
  • 14Chef’s Tip: I usually put the beef into a strainer, and dip the strainer into the sauce.
  • 15Add half the beef to each roll.
  • 16Add the pepper/mushroom/onion mixture on top.
  • 17Cover with several slices of the provolone, the more the merrier.
  • 18Pop under a broiler until the cheese is bubbly, about 2 minutes.
  • 20Serve with some dipping sauce on the side, and maybe a bit more horseradish sauce. Enjoy.
  • 21Keep the faith, and keep cooking.
