Open-Faced Prime Rib Sandwiches are the perfect way to use up the leftovers from my previous post's Date Night Prime Rib. Caramelized onions and melty provolone cheese top thinly sliced prime rib on a hoagie roll.
Phil and I have taken to making a tiny prime rib roast for the occasional, extra-special date night.
I have to admit: the purpose of doing this is mostly to have leftovers for these AWESOME open-faced prime rib sandwiches.
If you're making prime rib for Christmas Dinner, keep this recipe in the holster for the leftovers!
Open-Faced Prime Rib Sandwiches: about the meat
Phil talked me into buying a meat slicer, which I was firmly against.
After all, a meat slice is a space-eating "unitasker". But then I realized that it quickly paid for itself, and that we're saving a ton of money by not buying pre-sliced meat or cheese.
I'm a reluctant convert.
ESPECIALLY when Phil sliced our coveted prime rib into thin, gorgeous slices of medium-rare perfection.
But you can get away with not having a meat slicer.
To slice the meat as thinly as possible, freeze your leftover prime rib for about a half hour.
Then use a sharp chef's knife to carefully cut the semi-frozen meat into thin slices (it's easier to thinly slice meat when it's a bit firmer).
Making Open-Faced Prime Rib Sandwiches
Caramelized onion is wonderful with open-faced prime rib sandwiches.
I thinly slice some sweet Vidalia onion and sautée until it's just beginning to turn golden-brown.
Then, I add in the sliced prime rib, quickly sautée, and top with provolone slices.
Finally, I lid the skillet to let the cheese melt, and then it's go time.
To serve, I just place a spatula-full of the cheese, meat, and onion mixture on top of a toasted hoagie roll.
Leftover au jus from Date Night Prime Rib is perfect for serving.
After all, these open-faced prime rib sandwiches are fabulous for eating with a knife and fork, dipping each bite in the au jus.
If you don't have au jus, you could also mix a tiny bit of horseradish with a 1:1 mix of mayonnaise and sour cream, and slather that on the hoagie roll.
And there you have it! A not-fit-for Foodgawker mess of some of the most awesome comfort food/pub food EVER. I hope you love it!
