What Ingredients are in Philly Cheesesteak Casserole?
This Philly Cheesesteak Casserole transforms the iconic sandwich into a delicious baked dish that’s perfect for family dinners. I’ve gathered all the classic elements of a traditional Philly cheesesteak and reimagined them in casserole form. The combination of thinly sliced beef, sautéed peppers and onions, and that signature cheese topping creates a mouthwatering meal that’s both satisfying and simple to prepare.
- 4 slices of thick-cut white, sourdough, or Italian bread
- 4 slices of mozzarella cheese (or provolone/cheddar mix)
- 2 tablespoons halal butter, softened
- 1 tablespoon olive oil
- 2 cloves garlic, minced (or 1 teaspoon garlic powder)
- 1 tablespoon fresh parsley, chopped (or 1 teaspoon dried parsley)
- 2 tablespoons grated halal Parmesan cheese
- Pinch of salt
When shopping for these ingredients, quality matters—especially with the cheese. While traditional Philly cheesesteaks often use provolone or even Cheez Whiz, this casserole version works beautifully with mozzarella or a provolone/cheddar mix for that perfect melt. The bread serves as both structure and comfort in this dish, so choose something substantial that can hold up to the rich garlic butter mixture. And speaking of butter, using halal varieties guarantees this dish can be enjoyed by more people at your table.
How to Make This Philly Cheesesteak Casserole
Making this casserole starts with preparing a flavorful garlic butter mixture that really elevates the dish. In a small bowl, combine 2 tablespoons of softened halal butter with 1 tablespoon olive oil, 2 minced garlic cloves, 1 tablespoon fresh chopped parsley (or 1 teaspoon dried), 2 tablespoons of grated halal Parmesan cheese, and a pinch of salt.
Mix these ingredients until they’re well blended—this aromatic spread will be the foundation of our casserole’s incredible flavor.
Next comes the assembly, which is wonderfully straightforward. Take your 4 slices of thick-cut bread (white, sourdough, or Italian all work beautifully here) and spread the garlic butter mixture evenly on one side of each slice.
Place 2 slices, buttered side down, in a skillet over medium heat. Then, lay 2 slices of mozzarella cheese (or your provolone/cheddar mix if you prefer) on each bread slice in the pan. Top with the remaining bread slices, keeping the buttered side facing up this time.
Cook the sandwiches until the bottom becomes golden and crispy, which typically takes about 3-4 minutes. Then, carefully flip them over—I recommend using a wide spatula for this maneuver—and cook for another 3-4 minutes until the other side is equally golden and the cheese has melted into that irresistible gooey texture we’re after.
Once done, slice into portions and serve while still warm. The contrast between the crunchy, buttery exterior and the melty cheese inside creates a comfort food experience that’s hard to beat.
Philly Cheesesteak Casserole Substitutions and Variations
While our classic recipe creates a delicious comfort food experience, the beauty of this Philly Cheesesteak Casserole lies in its flexibility.
You can easily swap the beef for chicken or turkey if you’re watching calories, or mushrooms for a vegetarian twist. Not a provolone fan? Try Swiss, cheddar, or even pepper jack for extra heat.
I sometimes add roasted red peppers or jalapeños when I’m craving something spicy. Bell peppers can be red or yellow instead of green.
Want more substance? Mix in cooked pasta or crispy hash browns as the base. Truth is, this casserole adapts to whatever’s in your fridge—making weeknight dinner decisions so much simpler.
What to Serve with Philly Cheesesteak Casserole
Looking for the perfect sides to complement your Philly Cheesesteak Casserole?
I always go for a simple green salad with vinaigrette to cut through the richness. Roasted vegetables like broccoli or asparagus add color and nutrition to your plate.
For a heartier meal, crispy potato wedges or sweet potato fries hit the spot, though I’ve been known to double-carb with garlic bread, no regrets.
Coleslaw works surprisingly well too, adding crunch and tanginess.
My personal favorite? A pickle spear on the side.
That vinegary bite somehow makes the cheesy, meaty flavors pop even more.
Final Thoughts
This Philly Cheesesteak Casserole has become my go-to comfort food when I’m craving something hearty yet easy to make. The combination of tender beef, caramelized onions, and that gooey cheese layer never fails to satisfy my comfort food cravings.
What I love most is how versatile it is. Having leftovers? Even better—the flavors deepen overnight in the fridge.
Sometimes I switch up the cheese or add mushrooms when I’m feeling fancy.
Trust me, once you add this to your rotation, your family will request it weekly. Who knew Philly’s famous sandwich could transform into such a crowd-pleasing casserole?
