Preheat a skillet over medium-high heat.
Rub the beef sirloin with 1 tablespoon of olive oil, salt, pepper, and garlic powder.
Sear the beef in the skillet for 3-4 minutes on each side until browned. Reduce the heat to medium, cover, and cook to your preferred doneness (internal temperature of 130°F for medium-rare or 140°F for medium).
Remove the beef from the skillet and allow it to rest for 10 minutes before slicing it thinly against the grain.
In the same skillet, add 1 tablespoon of olive oil and 1 tablespoon of butter. Add the thinly sliced onions and cook on low heat, stirring occasionally, for about 15-20 minutes until they are golden brown and caramelized.
While the onions cook, prepare the aioli by combining mayonnaise, dijon mustard, horseradish, and chopped parsley in a small bowl. Mix well and set aside.
Preheat the oven to 350°F. Slice the sandwich rolls in half and lightly butter the insides with the remaining butter.
Place the sliced rolls on a baking sheet and toast in the oven for 5-7 minutes until lightly golden.
Top the bottom half of each toasted roll with a lettuce leaf, slices of beef, caramelized onions, and a provolone cheese slice.
Return the assembled sandwiches to the oven for 3-4 minutes, just until the cheese melts.
Spread the prepared aioli generously on the top half of each roll and place it on top of the sandwich.
Serve warm and enjoy your delicious beef sandwiches!
