Main ingredients

How to make this easy steak sandwich:

Beef Short Rib Roast – We use leftovers from our Succulent Smoked Short Rib by reheating it whole in the oven before thinly slicing to serve.
Toasted Ciabatta Bread – Italian ciabatta has the perfect balance of crispy crust and doughy interior that we want in our barbecue sandwich. We toast it to give it an even more satisfying texture.
Finely Sliced Provolone Cheese: To keep with the Italian theme, Provolone is a creamy Italian cheese that melts beautifully when sliced. Monterey Jack, Fontina, and Mozzarella cheese are good substitutes for Provolone if you need an alternative.
Caramelized Onions: Slowly roasted onions make everything better. Cook them slowly in oil and salt at a lower temperature until golden brown to add an incredibly sweet touch to your sandwich.
Horseradish Mustard: While horseradish or mayonnaise are perfect ingredients for this recipe, I prefer a bit more zing with yellow or Dijon mustard. However, horseradish mustard combines all of the above in one condiment. You can make your own or buy a store-bought version online like Annie’s Horseradish Mustard .

Ingredients

1 pound smoked ribs
1 sliced white onion
1 teaspoon kosher salt
2 loaves of ciabatta bread
8 slices of provolone cheese
2 arugula cups
4 tablespoons Horseradish Mustard

Instructions

Preheat the oven at 120°C
Heat the oil in a cast iron skillet over low heat. Add chopped onions and a pinch of salt. Heat, stirring occasionally, until soft and golden. 30-40 minutes.
While the onions are caramelizing, move on to the meat. Line a small baking sheet with aluminum foil and add a few squirts of cooking spray. Place the rib in the pan and cover with foil. Heat in the oven for 10-15 minutes until the meat is heated through.
Remove the ribs from the oven and cut into thin slices.
Halve the ciabatta bread lengthwise at a 45 degree angle. Place slices of provolone in the center of each sandwich.
Toast the ciabatta under the grill over high heat for 2-3 minutes until the provolone begins to melt.
Remove the bun from the grill and top each sandwich with hot ribs, caramelized onions, arugula, and horseradish mustard. Serve and enjoy immediately.
