How to make a Prime Rib Dip

This is just the overview so you can see what you’re actually getting into here. When you are cooking, you’ll want to use the full recipe at the bottom of the page.



Thinly slice your cooked prime rib. Use the sharpest knife you have and make the thinnest slices possible. It is okay if it is more “shaved” than sliced. A GOOD electric knife works well for this to, as does a meat slicer.


Heat Au Jus

Heat your Au Jus in a pot on the stove until it is simmering.



Slice your rolls and toast the insides.


Build ’em

Melt two slices of cheese on each roll. Add the sliced beef to the simmering au jus. Pile it on the rolls.



Serve hot with an extra side of au jus for dunking.

Prime Rib French Dip FAQ

What’s the best way to store leftovers?

Keep these sandwiches disassembled if you are going to have more than you can eat in a sitting. Assemble right before you eat. The shaved meat will keep well for 3-4 days.

What can you use to make the au jus?

We love the Johnny’s Au Jus mix around here. I keep a bottle of it around basically always for soups, stews, gravy, and au jus. If you don’t have any, you can use the drippings from your rib roast.

What about the sub buns?

We usually use hoagie rolls from the grocery store for French dips, but once in a while I’ll get ambitious and make my own homemade rolls.
