🧅🧀 Ingredients You’ll Need
This dish uses simple, accessible ingredients but delivers incredible flavor.
Main Ingredients
- 1 pound ground beef (or thin-sliced steak, shaved beef, or deli roast beef)
- 1 tablespoon olive oil
- 1 large onion, sliced
- 1 green bell pepper, sliced
- 1 red bell pepper, sliced
- 8 oz mushrooms, sliced (optional but delicious)
- 2 teaspoons Worcestershire sauce
- 1 teaspoon garlic powder
- Salt and black pepper, to taste
- 8 slices provolone cheese (plus extra if you want it cheesier)
- 1 can refrigerated biscuits or 4 cups cubed French bread or crescent dough sheet
- 1 cup shredded mozzarella (optional for extra meltiness)
- 4 eggs
- 1 cup milk or half-and-half
Using biscuits or bread gives the bake a soft, slightly chewy base that mimics good sandwich bread. Crescent dough gives a flakier, pastry-like finish.
🔪 Step-by-Step Instructions
1. Cook the Beef
Start by heating olive oil in a large skillet over medium-high heat. Add the ground beef or shaved steak and cook until browned. Break it into small crumbles as it cooks. Sprinkle in garlic powder, salt, pepper, and Worcestershire sauce. Once cooked, remove excess grease and set the meat aside.
2. Sauté the Veggies
In the same skillet, add your sliced onions and bell peppers. Cook until they’re soft, sweet, and lightly caramelized—about 7–10 minutes. Add mushrooms if you’re using them and sauté until tender. These vegetables bring the classic cheesesteak flavor, so don’t rush this step.
3. Prepare Your Casserole Base
Choose your base:
- Biscuit dough: Cut each biscuit into quarters.
- French bread: Cube into bite-sized pieces.
- Crescent dough: Press the sheet into the bottom of the casserole dish.
Spray a 9×13 baking dish with nonstick spray and spread your biscuit pieces or bread cubes evenly across the bottom.
4. Layer the Ingredients
Now comes the fun part: building the cheesesteak layers.
- Spread the cooked beef evenly over the bread or biscuit layer.
- Top with the sautéed peppers, onions, and mushrooms.
- Lay slices of provolone cheese over the top so the whole dish is blanketed in melty goodness.
If you want extra cheesiness, sprinkle shredded mozzarella on top.
5. Mix the Egg Custard
Whisk together eggs and milk in a bowl. This mixture helps bind everything together and gives the casserole its satisfying, slightly puffy texture. Pour the custard evenly over the assembled ingredients.
6. Bake
Place the casserole in a preheated 350°F (175°C) oven and bake for 30–40 minutes, or until everything is cooked through and the cheese is bubbling and slightly golden.
Let the bake cool for 5–10 minutes so it sets and slices cleanly.
😍 How to Serve Your Philly Cheesesteak Bake
This dish stands beautifully on its own, but a few simple sides or toppings can take it to the next level:
- With a crisp side salad
- With roasted potatoes or fries
- With a drizzle of hot sauce or spicy mayo
- With sautéed mushrooms on top
- With pickled jalapeños for heat
- With extra provolone melted over the top for cheesier indulgence
It’s also great as leftovers for lunch the next day—the flavors deepen even more.
🔄 Variations to Try
This recipe is incredibly flexible. Here are some fun variations:
Chicken Cheesesteak Bake
Use cooked shredded chicken or sliced chicken breast instead of beef. Add a sprinkle of Italian seasoning for extra flavor.
Spicy Philly Bake
Use pepper jack cheese, add jalapeños, and increase the Worcestershire and garlic.

Add roasted potatoes, bacon bits, or extra mushrooms for maximum heartiness.
White Sauce Version
Mix 4 ounces of cream cheese into the beef mixture for a creamy, rich base.
