Prime Rib French Dip
Prime Rib Recipes and Leftover Prime Rib Recipes are my specialty! Any of my will make great leftovers to use to make a prime rib French dip sandwich.
Popular prime rib recipes to consider making include The Internet’s Original Prime Rib Roast, Reverse Seared Prime Rib, or Smoked Prime Rib.
The leftover prime rib featured in the pictured sandwich utilized my ribeye roast recipe with prime rib seasoning.
Ingredients To Make A Prime Rib Dip
Here are the main ingredients needed to make a French Dip Sandwich Recipe. The full list can be found in the recipe card.
- Leftover Prime Rib: I created and tested this recipe using one 1/4″-1/2″ slice of beef from a leftover prime rib roast. If you prefer more of a classic French dip sandwich, shave or thinly slice the beef instead.
- Cheese: add slices of provolone, Swiss, or cheddar to add creaminess to the sandwich.
- Bread: any hearty roll will work, such as French roll, hoagie roll, or baguette. You can also make or buy garlic bread, which will save you the time of making the garlic butter spread.
- Au Jus: If you have leftover prime rib au jus this is a great way to use it up. If not, whip up a batch using homemade au jus mix or a store bought packet.
Variations
Here are a few variation ideas to consider when making leftover prime rib French dip sandwiches:
Add In Onions: Top with caramelized onions, fried onions, or Bacon Onion Jam for even more flavor and crunch.
Roast Beef Sliders: Use slider bread to make prime rib sliders instead of individual sandwiches.
Breakfast French Dip Sandwich: Throw an egg on it, like used in this open face roast beef sandwich, to make it a breakfast recipe.
Horseradish French Dip: Add a layer of tangy horseradish sauce for a zesty kick.

Recipe Tips And Notes
- Salt: I highly recommend sticking to unsalted butter. The prime rib rub, as well as the au jus will be already high in sodium.
- Garlic Bread: Utilizing pre-made garlic bread will cut down on prep time. Hello, Texas Toast.
- Au Jus: serve with hot au jus. The au jus will help keep the meat warm and soft while eating.
- Serve immediately for the best texture. The longer it sits, the softer the bread will become.
