Step 2: Cook the Meat and Vegetables
- Heat 2 tablespoons of olive oil in a large skillet over medium-high heat.
- Add the onions and bell peppers, seasoning with salt, pepper, and garlic powder. Sauté for 5–7 minutes until softened and lightly caramelized.
- Push the vegetables to the side, add the steak, and cook until browned, about 3–4 minutes.
- Mix the vegetables with the steak, then remove from heat.
Step 3: Make the Cheese Sauce
- In a small saucepan over medium heat, melt 2 tablespoons of butter.
- Stir in 2 tablespoons of flour and cook for 1 minute, whisking constantly to avoid lumps.
- Gradually whisk in 1 cup of milk, cooking until thickened (about 3–5 minutes).
- Reduce heat to low and stir in 1 cup of shredded cheese until fully melted and smooth.
- Optional: add ½ teaspoon mustard for a tangy depth.
Step 4: Assemble the Baked Philly Cheesesteak
- Place the sliced hoagie rolls or baguette pieces in the prepared baking dish.
- Layer the cooked steak and vegetable mixture evenly over the bread.
- Pour the warm cheese sauce generously over the top, making sure every piece of bread gets some cheesy goodness.
Step 5: Bake to Perfection
- Cover the dish with foil and bake at 375°F (190°C) for 15 minutes.
- Remove the foil and bake for an additional 5–7 minutes until the top is bubbly and slightly golden.
- Garnish with fresh parsley if desired.
Step 6: Serve and Enjoy
- Allow the casserole to cool for 2–3 minutes before serving.
- Use a spatula to lift portions onto plates.
- Pair with a side salad, pickles, or fries for a complete meal.
Tips for the Best Baked Philly Cheesesteak

- Steak slicing: Thinner slices cook faster and stay tender.
- Add heat: Mix in sliced jalapeños or hot sauce for a spicy kick.
- Make ahead: Prepare the meat and cheese sauce a day in advance, then assemble and bake when ready.
