📝 Ingredients
For the Casserole:
- 1 lb ground beef (or thinly sliced steak)
- 2 tbsp olive oil
- 1 small onion, thinly sliced
- 1 green bell pepper, sliced
- 1 red bell pepper, sliced
- 8 oz mushrooms, sliced (optional but recommended)
- 3 oz cream cheese, softened
- ½ cup sour cream
- 1 tsp garlic powder
- 1 tsp onion powder
- ½ tsp paprika
- Salt and pepper to taste
For the Cheesy Topping:

📍 Ingredient Notes
- Ground Beef vs. Steak: Ground beef makes this a quicker and more budget-friendly weeknight dinner, but shaved ribeye gives a more authentic Philly taste.
- Peppers: Use a mix of red and green; the combo adds sweetness and flavor depth.
- Mushrooms: Optional, but they add a savory “steakhouse” flavor.
- Cheese: Provolone gives classic Philly cheesesteak flavor—don’t skip it! Mozzarella adds stretch and meltiness.
- Cream Cheese & Sour Cream: Create a creamy, rich sauce that replaces the need for bread.
👩🍳 Step-by-Step Instructions
Step 1: Sauté the Veggies
Heat olive oil in a large skillet. Add sliced onions and bell peppers, cooking until they soften and become slightly caramelized. Add mushrooms and cook until tender. Remove veggies from the pan and set aside.
Step 2: Cook the Meat
In the same skillet, add ground beef or shaved steak. Season with garlic powder, onion powder, paprika, salt, and pepper. Cook until browned, breaking apart the meat as it cooks. Drain excess grease if needed.
Step 3: Make the Creamy Sauce
Reduce heat to low and stir in cream cheese. Once melted, add sour cream and gently mix until the meat is coated in a creamy, velvety sauce.
Step 4: Assemble the Casserole
Preheat your oven to 375°F (190°C). Spread the cooked veggie mixture into the bottom of a greased 9×13 baking dish, then layer the creamy beef mixture on top.
Step 5: Add the Cheese
Sprinkle provolone and mozzarella evenly over the top, creating a thick cheesy layer that will melt into golden, bubbly perfection.
Step 6: Bake
Bake for 15–18 minutes, or until the cheese is melted, bubbly, and slightly golden on the edges. Let cool 5 minutes before serving for the perfect slice.
