Description

Ingredients

• 1-1½ lbs leftover prime rib, or other steak (about 4-6 oz per person)
• 1 white onion, sliced
• 8 slices provolone cheese
• 2 cups arugula (or other crunchy green), lightly packed
• 1 baguette
• Horseradish Cream Sauce (below)
• ¾ cup sour cream
• 3 tablespoons horseradish
• 1 tablespoon Dijon mustard
• 2 tablespoons fresh squeezed lemon juice
• 1 tablespoon white wine vinegar
• ½ teaspoon salt
• 2 tablespoon fresh chives, finely chopped

Directions

• Preheat oven to 325 degrees.
• To make the caramelized onions: heat up a large pan on the stovetop to medium heat then add 2 tablespoons olive oil and the sliced onions. Stir occasionally until the onions are soft, golden/starting to brown, and sweet to the taste (roughly 30-40 minutes). Remove from heat. *You may need to adjust the heat and turn it down if they are browning too fast.
• In the meantime, place your leftover prime rib in a large cast iron (or oven proof) pan and place in the oven to heat up (approx 15 - 20 minutes). Remove from oven and slice into thin slices.
• To build your sandwiches: cut the baguette into 4 equal size pieces and cut in half, lengthwise. Place on a baking sheet, open faced, and place two pieces of cheese on bottom half of each sandwich.
• Place under the broiler for a couple minutes to melt the cheese (paying close attention to not burn the bread).
• Once the cheese is melted, remove from the oven and build each sandwich: add 3-4 slices of the warm steak, a small handful of arugula, and a couple tablespoons of caramelized onions, then top with 1-2 tablespoons of creamy horseradish sauce. Serve immediately and enjoy the heck out of these epic sandwiches.
• Place all ingredients in a bowl and mix together.
