Philly Cheesesteak Casserole
Introduction
Philly Cheesesteak Casserole transforms the beloved flavors of a classic cheesesteak into an easy, comforting baked dish. Tender beef, sweet onions, crisp-tender green peppers, and plenty of melted cheese come together in one satisfying casserole. It’s a wonderful choice for a weeknight dinner, family meal, or casual gathering.
Origin
The inspiration comes from the famous Philly cheesesteak, a sandwich associated with Philadelphia, Pennsylvania. The original sandwich traditionally features thinly sliced beef cooked with onions and served on a long roll, often with provolone or other cheese. This casserole version removes the bread and turns those familiar flavors into a hearty oven-baked meal.
Cultural Significance
The Philly cheesesteak has become one of Philadelphia’s most recognizable foods and an iconic example of American sandwich culture. Its combination of beef, onions, and melted cheese is simple but deeply satisfying. Casserole versions reinterpret that classic combination for home cooks who want the same flavors in a convenient family-style dish.
Ingredients & Quantities
500 g (about 1.1 lb) thinly sliced beef steak
1 large green bell pepper, chopped
1 medium onion, sliced
2 cups (200–225 g) shredded mozzarella or provolone cheese
2 tablespoons olive oil or butter
2 cloves garlic, minced
½ teaspoon salt
½ teaspoon black pepper
½ teaspoon Italian seasoning, optional
¼ teaspoon smoked paprika, optional
Optional Additions
For extra flavor or texture, consider adding:
225 g sliced mushrooms
2 tablespoons Worcestershire sauce
1 tablespoon Dijon mustard
Sliced jalapeños for heat
A splash of beef broth for extra moisture
Thinly sliced red or yellow bell peppers
A small amount of cream cheese for a richer casserole
Crispy fried onions for topping
Tips for Success
Slice the beef very thinly so it cooks quickly and remains tender.
If possible, partially freeze the steak for 20–30 minutes before slicing; this makes thin slicing much easier.
Don’t overcrowd the skillet. Cook the beef in batches if necessary so it browns rather than steams.
Cook the vegetables until tender but still slightly crisp.
Provolone gives the dish a more traditional cheesesteak flavor, while mozzarella creates an especially stretchy cheese topping.
Don’t overbake after adding the cheese; you only need enough time for it to melt and become lightly golden.
Let the casserole rest for 5 minutes before serving.
Instructions
1. Prepare the Oven
Preheat the oven to 400°F (200°C). Lightly grease a baking dish.
2. Cook the Beef
Heat 1 tablespoon of olive oil or butter in a large skillet over medium-high heat.
Add the thinly sliced beef, season with salt and black pepper, and cook for approximately 2–4 minutes, stirring occasionally, until browned. Remove the beef and set aside.
3. Cook the Vegetables
Add the remaining oil or butter to the skillet. Add the chopped green pepper and sliced onion.
Cook for about 5–7 minutes, stirring occasionally, until the vegetables soften and the onion becomes lightly caramelized. Add the garlic during the final minute.
4. Combine
Return the cooked beef to the skillet and stir everything together. Add Worcestershire sauce or other optional seasonings if desired.
Transfer the mixture to the prepared baking dish and spread evenly.
5. Add the Cheese
Sprinkle the shredded mozzarella or provolone evenly over the top.
6. Bake
Bake uncovered for approximately 10–15 minutes, or until the cheese has melted and is bubbling around the edges.
For a more golden top, place the casserole under the broiler for 1–2 minutes, watching carefully.
7. Rest and Serve
Allow the casserole to rest for about 5 minutes before serving. Garnish with fresh parsley or sliced green onions if desired.
Description
