Arrange your oven rack in the middle position. Preheat the broiler. Line a baking sheet with parchment paper and set aside.
Using a sharp chef's knife, slice the prime rib thinly, making sure to remove any excess fat.
Divide the baguette into four equal sections. Slice each section lengthwise, ensuring not to cut completely through, keeping the halves attached.
Open the bread and evenly distribute two tablespoons of horseradish sauce (4 tablespoons in total per sandwich) on both interior sides.
Layer a few slices of prime rib and one slice of cheese on top. Repeat the same process to assemble the rest of the sandwiches. Transfer them onto the prepared baking sheet.
Broil for 2 minutes or until the cheese is melted.
Remove from the oven and top each sandwich with fresh arugula or caramelized onion (if using).
Taste for seasoning and add more if necessary.
Serve while they are still warm.
