Ingredients

Servings

Sandwich:

  • 12-15 oz prime rib thinly sliced, leftover
  • 4 ciabatta rolls or 8 slices of baguette bread
  • 4 lices swiss cheese or provolone cheese, optional
  • butter or olive oil, for grilling or toasting

Caramelized Onions:

  • 2 large onion thinly sliced, yellow
  • 2 tablespoons butter
  • salt to taste
  • black pepper to taste
  • 1 pinch sugar optional

Horseradish Mayo:

  • 1-2 tablespoons horseradish sauce adjust to taste
  • 2-3 tablespoons mayonnaise

Salad:

  • 2 cups arugula or baby arugula
  • 1 tablespoon olive oil
  • 1 teaspoon lemon juice

Optional Au Jus for Dipping:

  • Reserved juices from the cooked prime rib
  • beef broth if needed, or beef stock
  • salt to taste
  • black pepper to taste

Instructions

  1. Caramelize the Onions: In a pan, melt butter over medium-high heat. Add the thinly sliced onions and let them get brown on the bottom before turning. Reduce heat to medium-low and simmer until they become soft and caramelized. This process can take 20-30 minutes. Season with a pinch of sugar (optional), salt, and pepper to enhance the caramelization process. Stir occasionally.
  2. Prepare the Horseradish Sauce: In a small bowl, mix horseradish sauce and mayonnaise. Adjust the ratio to your preferred level of spiciness. Set aside.
  3. Toss the Salad: In a small bowl, toss the arugula with the olive oil and lemon juice until well coated. Set aside.

Assemble the Sandwich:

  1. Preheat a grill pan or skillet over medium heat. Alternatively, you can use a toaster or oven to toast the bread. Butter one side of each slice of bread.
  2. Spread the horseradish-mayo sauce on the unbuttered side of one slice of bread.
  3. Layer the thinly sliced prime rib and provolone or Swiss cheese on top (if using).
  4. On the other slice of bread, spread the caramelized onions.
  5. Put the two slices of bread together with the spreads and fillings inside.
  6. Cut the sandwich in half, and serve it with your favorite sides like coleslaw, pickles, or potato chips.

Serve with Optional Au Jus:

  1. In a small saucepan, heat the reserved juices from the cooked prime rib. If needed, add a bit of beef broth to adjust the consistency. Season the au jus with salt and pepper to taste.
  2. Serve the sandwich with a side of the optional au jus for dipping.

Notes

  • Choose the Right Bread: Select a sturdy bread like a baguette or ciabatta that can hold up to the juicy meat and toppings.
  • Balance Flavors: Consider the balance of flavors and textures in your sandwich. Sweet, tangy, creamy, and crunchy elements can all enhance the experience.
  • Layering Matters: Arrange the ingredients thoughtfully. Place condiments and spreads on the bread’s interior to prevent sogginess, and evenly distribute the prime rib, cheese, and vegetables for each bite.
  • Sauce Placement: If using au jus or another sauce, consider dipping it on the side to prevent the bread from getting too soggy.
  • Toast the Bread: Toasting the bread adds a delightful crunch and helps keep it from becoming overly soft from the sandwich fillings.
