The Origin of Philly Cheese Steak

The Philly cheese steak sandwich originated in Philadelphia in the early 20th century and quickly became a beloved local staple. Traditionally made with thinly sliced beefsteak, melted cheese, and sometimes onions and peppers, the sandwich is typically served on a long hoagie roll. Over the years, variations of this classic have emerged, including the casserole version which offers a unique twist on the original.

Ingredients and Preparation

To create a Philly Cheese Steak Casserole, you’ll need the following ingredients:

  • 1 1/2 pounds lean ground beef
  • 2 bell peppers (any color, though green is traditional)
  • 1/2 yellow onion
  • 1 clove garlic
  • 1 teaspoon seasoned salt (like Lawry’s or Morton’s)
  • 4 slices of Provolone cheese
  • 4 large eggs
  • 1/4 cup heavy cream
  • 1 teaspoon hot sauce (optional, for a kick)
  • 1 teaspoon Worcestershire sauce

Preparation Steps:

Preheat Oven: Set your oven to 350 degrees Fahrenheit. Prepare a 9×9-inch baking dish by spraying it with non-stick spray.

Prep the Veggies: Dice the bell peppers and onion into bite-sized pieces. Mince the garlic.

Cook the Beef: In a skillet over medium heat, cook the ground beef until it’s browned and crumbled. Drain any excess fat.

Sauté Vegetables: Add the diced bell peppers, onions, and minced garlic to the skillet with the beef. Cook until the vegetables are tender.

Season: Stir in the seasoned salt to the beef and vegetable mixture.

Layer the Ingredients: Transfer the beef mixture to the prepared baking dish. Lay slices of Provolone cheese on top of the beef mixture.

Make the Egg Mixture: In a bowl, whisk together the eggs, heavy cream, hot sauce, and Worcestershire sauce. Pour this mixture over the beef and cheese in the baking dish.

Bake: Place the baking dish in the preheated oven and bake for about 20-25 minutes, or until the eggs are set and the cheese is melted and bubbly.

Serve: Let the casserole cool slightly before serving. Enjoy!
