Ingredients
This recipe makes 6 generous servings.
For the Beef & Vegetables
- 1 tablespoon olive oil
- 1 pound thinly sliced sirloin steak or shaved beef (or lean ground beef for an easier option)
- 1 medium yellow onion, thinly sliced
- 1 large green bell pepper, cored and thinly sliced
- 1 cup sliced mushrooms (optional, but highly recommended!)
- 1 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
For the Creamy Cheese Sauce
- 4 ounces cream cheese, softened
- 1/2 cup milk (any kind works, whole milk for richer sauce)
- 1/2 cup beef broth
- 1/4 teaspoon Dijon mustard (optional, for extra depth)
- Pinch of salt and black pepper
- 1 cup shredded provolone cheese, divided (or mild cheddar/mozzarella blend)
- 1/2 cup shredded Monterey Jack cheese (for extra meltiness)
For the Topping
- 1/4 cup chopped fresh parsley, for garnish (optional)
Step-by-Step Instructions
-
Step 1: Prep Your Oven and Pan
Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish. This prevents sticking and makes cleanup a breeze.
Small tip: A light spray with cooking oil works perfectly for greasing the dish.
-
Step 2: Sauté the Vegetables
Heat olive oil in a large skillet or cast-iron pan over medium-high heat. Add the sliced onion, green bell pepper, and mushrooms (if using). Sauté for 5-7 minutes until the vegetables are tender-crisp and slightly softened. Remove the vegetables from the skillet and set them aside in a bowl.
Small tip: Don’t overcrowd the pan. If you have a smaller skillet, sauté veggies in two batches for better browning.
-
Step 3: Cook the Beef
Add the thinly sliced sirloin steak or shaved beef to the same skillet. If using ground beef, break it up as it cooks. Season the beef with garlic powder, onion powder, salt, and black pepper. Cook for 5-7 minutes, stirring occasionally, until the beef is fully browned and cooked through. Drain any excess grease from the pan.
Small tip: For thinly sliced steak, cook quickly to avoid toughness. Ground beef will take a bit longer.
-
Step 4: Make the Creamy Cheese Sauce
Reduce the heat to medium-low. Add the softened cream cheese, milk, beef broth, and Dijon mustard (if using) to the skillet with the beef. Stir continuously until the cream cheese is fully melted and the sauce is smooth. Season with a pinch of salt and pepper.
Small tip: Ensure your cream cheese is at room temperature for a lump-free, smooth sauce.
-
Step 5: Combine and Layer
Stir half of the shredded provolone cheese and all of the Monterey Jack cheese into the creamy sauce in the skillet. Continue stirring until the cheese is melted and fully incorporated. Then, add the sautéed vegetables back into the skillet with the beef and cheese sauce. Stir everything together gently to combine all the delicious ingredients.
Small tip: This step creates the core flavor of your casserole. Make sure everything is well mixed!
-
Step 6: Bake the Casserole
Pour the entire beef and vegetable mixture into your prepared 9×13 inch baking dish. Spread it evenly. Sprinkle the remaining half cup of shredded provolone cheese over the top of the casserole. This will create a beautiful, bubbly, golden crust.
Small tip: For extra browning, you can sprinkle a little paprika on top of the cheese before baking.
-
Step 7: Finish and Serve
Bake for 20-25 minutes, or until the casserole is bubbly around the edges and the cheese on top is melted and lightly golden. Remove from the oven and let it rest for 5 minutes before serving. Garnish with fresh chopped parsley if desired. Scoop and enjoy your amazing Philly Cheesesteak Casserole!
Small tip: Resting the casserole allows the flavors to meld and the sauce to set slightly, making it easier to serve.
Tips & Variations
- Gluten-Free Option: This casserole is naturally gluten-free if you ensure your beef broth is GF. No changes needed to the main recipe!
- Vegan or Vegetarian Option: Replace the steak with sliced portobello mushrooms, extra bell peppers, or a plant-based ground “meat” alternative. For the cheese sauce, use a dairy-free cream cheese and your favorite vegan shredded cheeses.
- Add More Vegetables: Feel free to toss in extra veggies like spinach, zucchini, or even a handful of chopped broccoli florets when sautéing the initial vegetables. They’ll add extra nutrients and flavor!
- Spicy Version: For a kick, add 1/2 teaspoon of red pepper flakes to the beef seasoning, or include some diced jalapeños with your sautéed vegetables. A dash of hot sauce in the cheese sauce works too!
- Different Cheeses: While provolone is classic, feel free to experiment with other melting cheeses like sharp cheddar, Gruyère, or even a sprinkle of Parmesan on top for extra savoriness.

Health Benefits
This Philly Cheesesteak Casserole isn’t just delicious; it also packs some great health benefits from its wholesome ingredients.
The star of the show, sirloin steak, is an excellent source of high-quality protein, essential for muscle repair and growth. It also provides important nutrients like iron, which helps transport oxygen in the blood, and zinc, crucial for immune function.
Bell peppers, especially green ones, are rich in Vitamin C, a powerful antioxidant that supports your immune system and skin health. They also offer dietary fiber, which aids digestion, and various B vitamins.
Onions contribute to the dish’s flavor and offer antioxidants and compounds that may help reduce inflammation. Mushrooms, if included, add even more vitamins like B vitamins and minerals, along with unique immune-boosting properties.
Dairy products like cream cheese and provolone provide calcium, vital for strong bones and teeth. While cheese should be enjoyed in moderation, it’s a good source of protein and fat that contributes to satiety, helping you feel full and satisfied.
