Where Did It Originate?

The original Philly cheesesteak was born in Philadelphia, Pennsylvania in the 1930s. Invented by Pat Olivieri, a hot dog vendor, the sandwich became a sensation for its combination of thinly sliced steak, onions, and melted cheese on a hoagie roll.

This casserole version takes inspiration from that classic sandwich and transforms it into a one-dish meal that’s easier to prep and feed a crowd.

Ingredients

• 1 lb ground beef (or thinly sliced steak)
• 1 tablespoon olive oil
• 1 green bell pepper, diced
• 1 small onion, diced
• 2 cloves garlic, minced
• 1 teaspoon Worcestershire sauce
• Salt and pepper to taste
• 4 oz cream cheese, softened
• ½ cup mayonnaise
• 1 cup shredded mozzarella cheese
• 1 cup shredded provolone cheese (or a mix of provolone and cheddar)
• 2 large eggs
• Optional: sautéed mushrooms or hot peppers for variation

Method of Preparation

Step 1: Sauté the Veggies and Meat

In a large skillet over medium heat, add olive oil. Sauté onions and bell peppers for 3–4 minutes until soft. Add garlic and cook for another minute. Add ground beef (or steak) and cook until browned. Drain any excess fat. Season with salt, pepper, and Worcestershire sauce.

Step 2: Mix the Base

In a large bowl, mix cream cheese, mayonnaise, and eggs until smooth. Add half of the shredded cheese and stir in the cooked meat and veggie mixture.

Step 3: Assemble the Casserole

Preheat oven to 350°F (175°C). Pour the mixture into a greased 9×13-inch baking dish. Top with remaining cheese.

Step 4: Bake

Bake uncovered for 25–30 minutes or until bubbly and golden brown on top.

Step 5: Serve

Let rest for 5 minutes before slicing. Serve warm with a side salad, garlic bread, or roasted vegetables.

Cooking Tips

• Use provolone or mozzarella for that authentic Philly cheese flavor.
• Soften the cream cheese ahead of time for smoother mixing.
• Add a touch of hot sauce or crushed red pepper for a spicy twist.
• If using steak, slice it very thinly against the grain for tenderness.

Mistakes to Avoid

• Overcooking the beef: Makes it dry and chewy. Cook just until browned.
• Skipping the cheese layering: Don’t mix all the cheese into the batter—save some for the gooey topping.
• Using cold ingredients: Let eggs and cream cheese come to room temperature for better consistency.
• Not draining fat: Too much grease can make the casserole soggy.

Serving Tips

• Garnish with chopped parsley or green onions for freshness.
• Great with a side of garlic bread, coleslaw, or roasted potatoes.
• Serve leftovers in a sandwich roll for a casserole-turned-hoagie experience.

Health Benefits of Ingredients

• Bell peppers and onions: Rich in antioxidants and Vitamin C.
• Lean beef: A good source of iron and protein.
• Eggs: Provide essential amino acids and healthy fats.
• Cheese: Contains calcium and vitamin B12, in moderation.
