Thinly sliced beef with melted cheese on a crusty hoagie roll, the Philly cheesesteak is a high protein American icon. This legendary sandwich is a must-try family comfort food.
Heat 1 tbsp olive oil in a large skillet over medium-high heat. Add the onions and bell peppers, stirring frequently, and sauté for 4–5 minutes until softened and lightly browned.
Push the vegetables to one side of the skillet. Add the remaining 1 tbsp olive oil and place the sliced ribeye steak in. Cook for 2–3 minutes, stirring occasionally, until beef is just cooked through and juicy.
Season the beef and vegetables with salt and black pepper, mixing well to distribute flavors evenly.
Layer provolone cheese slices over the cooked beef mixture, reduce the heat to low, and cover. Let the cheese melt for about 1 minute, then stir gently to combine the gooey cheese throughout the filling.
Slice hoagie rolls horizontally. Pile the hot beef, vegetable, and cheese mixture into each roll, making sure to portion the filling evenly. Serve immediately while hot and melty.
