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.

italian baguettes or batards
1/2 lb
prime rib, sliced thin and chopped
grapeseed oil, for sautéing
1/2 medium
yellow onion, cut pole-to-pole and sliced into thick half moons
1/2 medium
green bell pepper, seeds removed, and cut into 1/4-inch strips
6 oz
button mushrooms, stemmed and sliced
4-6 slice
provolone cheese
horseradish sauce
dipping sauce (au juice)


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.
