I keep it simple. There is no one perfect way to make this classic.

A fresh baguette, or slices of bread, leftover roast beef (more on that later), a creamy spread, crisp lettuce like romaine, and a slice of cheese liked shaved parmesan.

Thick sliced roast beef on a cutting board with pan juices and ingredients in the background.

5 pounds Strip Steak (or Beef Tenderloin) butcher tied
2 tablespoons extra virgin olive oil
1 ½ teaspoons sea salt
1 teaspoon ground black pepper
½ cup shallots
2 cup good port wine
3 tablespoons butter

Let the beef stand at room temperature for about 1 hour before roasting. Preheat the oven to 450 degrees fahrenheit.
Dice the shallots and set aside.
Pat the beef dry with a paper towel, this helps it sear in the pan which creates carmelization (aka Maillard Reaction). Rub the olive oil all over the beef and sides of the roast, spinkle with salt and pepper on all sides.
On medium-high heat, heat a large cast iron skillet, sear the beef on each side until golden brown and caramelized, and stir the shallots around in the pan. The shallots will turn dark, and that is ok, but don't let them burn, adjust your heat if necessary.
Turn off the stove, remove beef from the pan and rest on a large platter.
In the large skillet pan (don't clean it out!) add 2 cups of red wine (a good port prefered) and 3 tablespoons of butter, use a wooden spoon to scrape up all the bits known as the "fond" on the bottom of the pan. There is a lot of flavor down on the pan and you want that in your sauce! Next, add the beef back in the pan.
Carefully place the cast iron skillet into the 450 degree oven on the center rack, for 10 minutes, then flip over the beef for another 10 minutes.
The beef is done when internal temperature reaches medium rare 130-135 degrees, use a good accurate thermometer.
Remove from oven, rest 15 minutes, and slice thick with a good sharp knife for dinner portions and spoon the sauce over each portion, or slice thinly for sandwiches.
Serve with creamy horseradish sauce for dinner.

What Kind Of Beef Is Best?

For the best sandwich, go for a quality cut of beef at the grocery store. It will produce the best flavor and will be melt in your mouth tender.

PRO TIP: You can splurge and get a center-cut beef tenderloin roast, also called a filet of beef, or filet roast, that runs around $22 per pound. But I found a less expensive option…New York Strip Steak!

New York Strip steak tied into a roast by the butcher is a cost-effective option for this recipe and is amazing. It’s up to you, I found that the strip steak was well priced and just as delicious!

New York Strip Steak Benefits – cost-effective, tender, and full of flavor
Filet Tenderloin Benefits – more expensive, very tender, a premium cut
