🛒 Ingredients
1½ pounds thinly sliced beef steak, such as sirloin or ribeye
1 tablespoon olive oil
1 medium yellow onion, thinly sliced
2 bell peppers, thinly sliced
8 ounces mushrooms, sliced, optional
3 cloves garlic, minced
1 teaspoon Worcestershire sauce
1 teaspoon Italian seasoning
½ teaspoon smoked paprika
½ teaspoon black pepper
½ teaspoon salt, or to taste
4 ounces cream cheese, softened
½ cup beef broth
1 cup shredded provolone cheese
1 cup shredded mozzarella cheese
½ cup shredded cheddar cheese, optional
Fresh parsley, chopped, for garnish
👩🍳 Instructions
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). Lightly grease a 9 × 13-inch baking dish with cooking spray or a small amount of oil.
Step 2: Prepare the Beef
Slice the beef into thin strips if it is not already sliced. Pat it dry with paper towels and season with salt, black pepper, smoked paprika, and Italian seasoning.
Thinly sliced beef cooks quickly and gives the casserole a texture reminiscent of a traditional Philly cheesesteak.
Step 3: Cook the Beef
Heat the olive oil in a large skillet over medium-high heat. Add the beef in batches and cook for approximately 2–3 minutes per batch, stirring until browned. Avoid overcrowding the pan.
Transfer the browned beef to a plate. It does not need to be completely cooked through at this stage because it will finish cooking in the oven.
Step 4: Sauté the Vegetables
Using the same skillet, add the sliced onions, bell peppers, and mushrooms if using. Cook for approximately 5–7 minutes, stirring occasionally, until the vegetables begin to soften.
Add the minced garlic and cook for another 30 seconds. Stir in the Worcestershire sauce for extra savory flavor.
Step 5: Make the Creamy Filling
Reduce the heat to low. Add the softened cream cheese and beef broth to the skillet. Stir until the cream cheese melts into a smooth, creamy sauce.
Return the beef to the skillet and mix everything together. If the skillet is too small, combine the ingredients in a large bowl instead.
Step 6: Assemble the Casserole
Transfer the beef and vegetable mixture into the prepared baking dish. Spread it evenly, then sprinkle the provolone and mozzarella cheese over the top. Add cheddar if you prefer a sharper cheese flavor.
Step 7: Bake Until Bubbly
Bake uncovered for approximately 20–25 minutes, until the cheese is melted, the casserole is bubbling, and the beef is fully cooked.
For a golden cheese topping, broil for an additional 1–2 minutes, watching carefully to prevent burning.
Step 8: Rest and Serve
Remove the casserole from the oven and let it rest for 5 minutes. Garnish with freshly chopped parsley, if desired.
Serve warm while the cheese is gooey and the beef and vegetables are tender.

💡 Helpful Tips
Choose the right beef: Ribeye provides rich flavor and tenderness, while sirloin is a leaner alternative. Slice the beef thinly across the grain.
Avoid overcooking the beef: Brown it briefly before baking to help keep it tender. The exact cooking time depends on the thickness of the strips.
Use provolone for classic flavor: Provolone melts beautifully and complements the beef and peppers. Mozzarella adds extra stretchiness.
Don’t skip draining excess liquid: Mushrooms and vegetables release moisture as they cook. If the skillet looks watery, let the liquid reduce before assembling the casserole.
Customize the vegetables: Green bell peppers are classic, but red and yellow peppers add sweetness. Mushrooms are optional.
Make it spicy: Add crushed red pepper flakes or sliced jalapeños for a little heat.
Prepare ahead: Cook the beef and vegetables, prepare the filling, and refrigerate the mixture in a covered dish. Add the cheese and bake when ready, allowing extra time if the casserole is cold.
Store leftovers safely: Refrigerate leftovers in an airtight container within two hours and use within 3–4 days. Reheat thoroughly to 165°F (74°C). Freeze portions for up to 3 months for best quality.
❓ Questions & Answers
Q: What kind of beef works best for Philly Cheesesteak Casserole?
A: Ribeye and sirloin are excellent choices. Ribeye offers a richer flavor, while sirloin is generally leaner and works well when thinly sliced.

A: Absolutely. Stir in cooked pasta or add thinly sliced, partially cooked potatoes to create a heartier casserole. You may need to increase the sauce and baking time.
Q: What should I serve with Philly Cheesesteak Casserole?
A: A crisp green salad, roasted broccoli, green beans, cauliflower rice, or garlic bread makes a delicious accompaniment.
