What Is a Philly Cheesesteak Grilled Cheese?

A Philly Cheesesteak Grilled Cheese is a fusion sandwich that combines elements of a traditional cheesesteak with a classic grilled cheese. Instead of a hoagie roll, the filling is placed between slices of buttered bread and grilled until crispy and golden.

The original cheesesteak comes from Philadelphia and traditionally features thinly sliced beef, onions, and melted cheese served on a long roll. This recipe takes those flavors and transforms them into a pan-grilled masterpiece with a crispy crust and melty center.

Ingredients

8 slices thick sandwich bread (sourdough or Texas toast works best)
1 pound thinly sliced ribeye steak (or sirloin)
1 medium onion, thinly sliced
1 green bell pepper, thinly sliced
8 slices provolone cheese (or American cheese)
2 tablespoons butter (for cooking)
1 tablespoon olive oil
Salt, to taste
Black pepper, to taste
Optional: garlic powder or Worcestershire sauce for extra flavor

Instructions

Prepare the vegetables
Heat olive oil in a large skillet over medium heat. Add sliced onions and bell peppers. Cook for 6–8 minutes until softened and slightly caramelized. Remove from the skillet and set aside.
Cook the steak
In the same skillet, increase heat to medium-high. Add the thinly sliced steak, seasoning with salt and pepper. Cook for 2–3 minutes until browned and cooked through. Break apart pieces with a spatula if needed.
Combine filling
Return the cooked onions and peppers to the skillet with the steak. Mix well and cook for another minute. Remove from heat.
Assemble the sandwiches
Butter one side of each slice of bread. Place four slices butter-side down on a clean surface. Add a slice of cheese, a generous portion of steak mixture, and another slice of cheese. Top with the remaining bread slices, butter-side facing up.
Grill the sandwiches
Heat a skillet or griddle over medium heat. Place sandwiches onto the skillet and cook for 3–4 minutes per side until bread is golden brown and cheese is fully melted.
Rest and serve
Remove from heat and let rest for 1–2 minutes before slicing. Serve hot for the best texture and flavor.

Tips for the Best Philly Cheesesteak Grilled Cheese

Choose the Right Steak

Ribeye is ideal because of its marbling and tenderness. However, sirloin or shaved beef also works well if ribeye isn’t available.

Slice Thinly

Thin slices cook quickly and create the authentic cheesesteak texture. If slicing at home, partially freeze the steak for easier cutting.

Low and Slow Grilling

Cooking the sandwich over medium heat ensures the bread crisps evenly while the cheese melts fully without burning.

Butter vs. Mayo

Some cooks prefer spreading mayonnaise on the bread instead of butter for extra crispiness. Both methods work — choose your favorite.

Cheese Options

While provolone is traditional, you can experiment with other cheeses:

American cheese (extra creamy melt)
Mozzarella (stretchy texture)
Cheddar (sharper flavor)
Pepper jack (spicy kick)
Cheese sauce (ultra indulgent version)

Mixing cheeses can also create incredible flavor depth.

Delicious Variations

Mushroom Cheesesteak Grilled Cheese

Add sautéed mushrooms for earthy flavor and extra juiciness.

Spicy Version

Include jalapeños or hot sauce for heat lovers.

Garlic Bread Style

Spread garlic butter on the bread before grilling for extra flavor.

Chicken Cheesesteak

Substitute thinly sliced chicken breast for a lighter option.

Loaded Cheesesteak

Add bacon or extra cheese for an indulgent twist.

Serving Suggestions

This sandwich pairs beautifully with classic comfort sides:

French fries or sweet potato fries
Tomato soup
Pickles or coleslaw
Potato chips
Side salad for balance

For drinks, iced tea, lemonade, or soda complement the rich flavors perfectly.

Storage and Reheating

Refrigeration

Store leftover sandwiches in an airtight container in the refrigerator for up to 3 days.

Reheating

Reheat in a skillet over medium heat for best texture. Avoid microwaving if possible, as it can make the bread soggy.

Freezing

You can freeze assembled (ungrilled) sandwiches wrapped tightly for up to 2 months. Cook directly from frozen on low heat.

Nutritional Benefits

While this is definitely comfort food, it does provide:

High protein from steak
Calcium from cheese
Energy from carbohydrates
Vitamins from vegetables

You can lighten the recipe by using whole-grain bread, leaner beef, or reduced-fat cheese.
