Ingredients for Philly Cheesesteak Sandwich

For the Beef

• 2½–3 lbs petite sirloin, thinly sliced
• ½ tsp garlic pepper
• 1 tsp seasoned salt (or to taste)
• 1–2 tbsp vegetable oil for cooking

For the Veggies

• 1 large yellow onion, thinly sliced
• 1 red bell pepper, sliced
• 1 green bell pepper, sliced
• 1–2 tbsp vegetable oil for sautéing

For Assembly

• 8 hoagie rolls
• 8–10 slices provolone cheese
• Butter for toasting rolls

Ingredient Notes & Substitutions

• Beef options: Ribeye or top sirloin can substitute for petite sirloin. Freeze briefly for easier slicing.
• Cheese: Provolone is classic, but American cheese or even Cheese Whiz works for a creamy melt.
• Vegetables: Traditional Philly often uses only onions, but peppers add sweetness and color.
• Seasonings: Adjust salt and garlic pepper to taste; add a pinch of paprika or crushed red pepper for mild heat.

Step-by-Step Instructions

Step 1 – Prep the Beef

Place the sirloin in the freezer for 20–30 minutes to firm it up, making thin slicing easier. Slice against the grain into approximately ¼-inch pieces. Season with garlic pepper and seasoned salt.

Step 2 – Sauté the Veggies

Heat 1–2 tbsp of oil in a large skillet over medium-low heat. Add the sliced onions and bell peppers and cook until tender and slightly caramelized, about 8–10 minutes. Remove from skillet and set aside.

Step 3 – Cook the Beef

In the same skillet, add 1–2 tbsp oil over medium-high heat. Cook the sirloin in batches to avoid overcrowding the pan, searing until browned but still juicy, about 2–3 minutes per batch.

Step 4 – Combine & Melt Cheese

Return the cooked veggies to the skillet with the beef. Layer provolone slices over the mixture and cover the pan for 1–2 minutes until the cheese melts fully.

Step 5 – Toast & Assemble

Lightly butter the hoagie rolls and toast them in a skillet or oven until golden. Spoon the beef, veggie, and cheese mixture into each roll. Serve immediately.

Pro Tips for Success

1. Freeze the beef for easier slicing and more even cooking.
2. Cook the beef in small batches to prevent steaming instead of searing.
3. Caramelize the onions and peppers slowly for maximum sweetness.
4. Cover with a lid briefly after adding cheese to ensure it melts evenly.
5. Toast the rolls lightly for a crisp exterior that holds the sandwich together.
6. Use sharp provolone for a classic Philly flavor that balances the beef.

Flavor Variations

1. Spicy Cheesesteak: Add sliced jalapeños or a dash of crushed red pepper.
2. Mushroom Philly: Sauté mushrooms with the peppers and onions.
3. Cheese Lovers’ Version: Mix provolone with mozzarella for extra gooeyness.
4. Italian Style: Add a sprinkle of Italian seasoning or fresh basil.
5. Vegan-Friendly: Use seitan or portobello mushrooms with vegan cheese and rolls.

Serving Suggestions

• Serve with crispy fries, potato chips, or a simple green salad.
• Add pickles or banana peppers for tangy crunch.
• Pair with a cold soda, beer, or sparkling water.

Storage and Freezing Instructions

• Refrigerate: Store leftover beef and veggies in an airtight container for up to 3 days.
• Freeze: Place cooked beef mixture in freezer-safe containers for up to 2 months.
• Reheat: Warm in a skillet over medium heat and add fresh cheese before serving. Avoid microwaving to keep the beef tender.
