Preheat the oven to 350°F (175°C) and grease a 9×13 inch baking dish.
In a skillet over medium heat, add olive oil and sauté the onion and green bell pepper until softened, about 5 minutes.
Add garlic and cook for 1 more minute.
Add ground beef, salt, and pepper, and cook until beef is browned and cooked through. Drain excess fat.
Stir in the cream cheese until well combined and melted into the meat mixture.
Transfer the meat mixture into the prepared baking dish and spread evenly.
In a bowl, whisk together eggs and heavy cream. Pour over the meat mixture.
Top with shredded mozzarella and provolone cheese.
Bake for 30–35 minutes or until the casserole is set and the cheese is bubbly and golden.
Let cool for 5 minutes before serving.

You can substitute ground beef with thinly sliced steak for a more authentic Philly flavor.
Add mushrooms for extra texture and taste.
Use low-fat cream cheese for a lighter version.
