Ingredients and Why They Work

1 lb ground beef (or thinly sliced ribeye/sirloin) – The star of the dish, providing juicy, meaty flavor. Thinly sliced steak gives a more authentic Philly cheesesteak texture.
1 green bell pepper, diced – Adds a subtle sweetness and slight crunch, balancing the richness of the beef and cheese.
1 small onion, diced – Brings depth and aromatic flavor that caramelizes beautifully when cooked.
8 oz mushrooms, sliced (optional) – Adds umami richness for an extra layer of savoriness.
2 cloves garlic, minced – Delivers a fragrant punch that enhances all the other ingredients.
1 teaspoon Worcestershire sauce – Infuses a tangy, savory depth to the meat.
1 teaspoon salt & ½ teaspoon black pepper – Essential seasonings that elevate all flavors.
½ teaspoon smoked paprika (optional) – Adds a subtle smoky undertone that pairs perfectly with beef.
4 oz cream cheese, softened – Creates a creamy, luscious base that keeps the casserole moist.
1 cup shredded provolone cheese – Offers a classic cheesesteak flavor with a mild, melty texture.
1 cup shredded cheddar cheese – Provides sharpness and golden crust on top.
3 large eggs – Helps bind the casserole and adds richness.
½ cup heavy cream or milk – Adds creaminess, ensuring a tender, custard-like texture.
2 tablespoons olive oil or butter – For sautéing the meat and vegetables, adding flavor and preventing sticking.
Optional garnish: chopped parsley or green onions – Adds freshness and a pop of color.

Step-by-Step Instructions

1. Preheat Your Oven

Set your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish. This ensures the casserole doesn’t stick and bakes evenly.

2. Cook the Meat

In a large skillet over medium-high heat, heat olive oil or butter. Add the ground beef (or steak) and cook until browned, about 5–7 minutes, breaking it up as it cooks. Drain excess fat for a leaner result.

3. Sauté Vegetables

Add diced bell pepper, onion, and mushrooms to the skillet. Sauté until softened, about 5 minutes. Stir in minced garlic and cook for 30 seconds until fragrant.

4. Season the Mixture

Sprinkle in Worcestershire sauce, salt, pepper, and smoked paprika. Mix well. Stir in softened cream cheese, letting it melt and create a creamy, flavorful base.

5. Prepare the Egg Mixture

In a medium bowl, whisk eggs and heavy cream (or milk) until smooth. Add a pinch of salt and pepper. This mixture will bind the casserole and create a custard-like texture.

6. Assemble the Casserole

Spread the meat and vegetable mixture evenly in the prepared baking dish. Pour the egg mixture over the top, letting it soak down. Sprinkle provolone and cheddar cheese evenly on top.

7. Bake

Bake in the preheated oven for 25–30 minutes, until the top is golden brown and bubbling and the center is fully set.

8. Rest and Serve

Allow the casserole to cool for 5–10 minutes before slicing. Garnish with chopped parsley or green onions for freshness and color.
