Learn How To Make Au Jus for French Dip Sandwiches even if you don't have any drippings leftover from a roast!
For Easter this year, I served a boneless prime rib roast. It was awesome by the way. There's really no substitute for this amazing cut of meat. Here's the thing, as always, I way over ordered my roast. I bought a 14 pound roast and probably had 5 pounds left over. You can't just throw away prime rib, so repurposing it into something else is a must!
My husband suggested making French Dip Sandwiches with the leftovers, which I was willing to do but I had a problem. The problem being that the method I used to cook my roast, resulted in virtually NO drippings to make a proper Au Jus. If you think about it, it's a good thing, because that means all the "juice" stayed inside the roast, instead of out, making a ridiculously tender dinner.
In my usual problem solving mode, I said "screw it" and made it without the drippings. I didn't expect all the flavor to be there but I have to say, IT WAS and this was the best darn French Dip Sandwich I have ever had.
So if you don't have drippings leftover, then this recipe is for you! Heck, if you don't have leftover roast, just go ahead and use deli roast beef, you'll still have one tasty sandwich!
