Step 5: Add the Pasta or Bread

Choose your base:

Option 1 — Pasta version (classic casserole)

• Stir in the cooked pasta right into the skillet.

Option 2 — Bread version (more like the real sandwich)

• Spread the cubed bread into the casserole dish.
• Pour the beef mixture evenly over the top.

Both versions deliver the cheesesteak essence—just choose your style.

Step 6: Assemble and Add Cheese

Pour the entire mixture into your casserole dish.

Top it generously with:

• Shredded provolone or mozzarella
• A sprinkle of cheddar for added richness

Cheese should blanket the top for that perfect golden crust.

Step 7: Bake to Perfection

Bake uncovered for 18–22 minutes, or until:

• Cheese is melted
• Edges are bubbling
• Top is lightly golden

Let rest for 5 minutes before serving—this helps it set for cleaner slices.

🍽 How to Serve It

Serve warm with:

• A crisp green salad
• Garlic bread
• Pickles (Philly-style)
• Hot sauce or banana peppers on the side

It’s also fantastic for meal prep—just portion into containers and reheat.

🧀 Variations You Can Try

🔥 Spicy Philly Version

Add jalapeños, hot cherry peppers, or pepper jack cheese.

🍄 Mushroom Lover’s Casserole
