Step 3: Cook the Beef
In the same skillet, add the beef. Season with salt, pepper, garlic powder, and onion powder. Cook until browned and fully cooked, breaking it apart if using ground beef.
For extra cheesesteak flavor, add a splash of Worcestershire sauce or a few tablespoons of beef broth.
Step 4: Create the Creamy Layer
Lower the heat and stir in cream cheese or a simple cream sauce. Mix until smooth and lightly saucy—this helps bind the casserole and keeps it moist.
Step 5: Assemble the Casserole
Preheat your oven to 375°F (190°C).
In a greased baking dish:
- Spread the cooked pasta or potatoes evenly.
- Layer the beef mixture over the base.
- Add the sautéed vegetables.
- Top generously with sliced or shredded cheese.
Step 6: Bake to Perfection
Cover loosely with foil and bake for about 20 minutes.
Remove the foil and bake an additional 10–15 minutes, or until the cheese is melted, bubbly, and lightly golden on top.
Step 7: Rest and Serve
Let the casserole rest for 5 minutes before serving. This helps the layers set and makes serving easier.
Serving Ideas
- Pair with a simple green salad for balance.
- Serve with garlic bread or dinner rolls for a true comfort-meal experience.
- Add pickled peppers or hot sauce on the side for a spicy kick.
Tips for Success
- Slice beef thinly against the grain for tenderness.
- Provolone gives the most authentic Philly flavor, but mozzarella adds extra stretch.
- Make it ahead and refrigerate—just add 10 extra minutes to baking time.
