Ingredients:
1 loaf Italian bread
2 teaspoons garlic, minced
½ cup unsalted butter, softened
1 teaspoon kosher salt
½ teaspoon pepper
1 pound ribeye steak
Black pepper, to taste
1 tablespoon extra virgin olive oil
1 large yellow onion, thinly sliced
1 green bell pepper, thinly sliced (optional)
1 ½ cups mozzarella cheese, shredded
½ cup parmesan cheese
Parsley, chopped for garnish
Instructions:
Preheat oven to 350°F. Line a baking sheet with parchment paper.
Slice the loaf of bread lengthwise into two halves. Place both halves of the bread onto the lined baking sheet, cut side up.
In a small bowl, combine the garlic, butter, salt, and pepper. Spread an equal amount of the mixture over the cut sides of the bread. Set aside while you make the Philly cheesesteak toppings.
Slice the meat into thin strips. Season strips with salt and pepper and set aside.
To a large cast-iron skillet over medium heat, add olive oil and butter. Once the butter is melted and the oil is hot, add onions. Cook, stirring frequently until caramelized (about 10-15 minutes). If using green peppers, add them to the skillet in the final 5 minutes of cooking the onions. Transfer onions (and peppers) to a plate and cover to keep warm.
To the same skillet over medium heat, add the ribeye slices.
Using two spatulas, shred the meat. Use one spatula to hold the meat in place and the other to pull it apart. (This step helps tenderize the meat while it cooks.)
Continue cooking until the meat is cooked through, but not crisp (about 2 minutes).
Divide the meat equally between both halves of the bread. Then, top each with onions and green peppers (if using). Top with shredded mozzarella and parmesan, ensuring all the meat is covered with cheese. Bake for 12-14 minutes or until golden brown.
Garnish with parsley. Slice the bread into 8 portions (or your desired servings) and serve
