Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.

In a skillet over medium heat, cook the ground beef (or steak slices) until browned. Drain excess fat and set aside.

In the same skillet, heat olive oil and sauté the onions, bell peppers, and garlic until soft and fragrant.

Return the meat to the skillet and stir in cream cheese until melted and well combined. Season with salt, pepper, and Italian seasoning if using.

In a separate bowl, whisk together eggs and heavy cream.

Spread the meat and veggie mixture evenly in the prepared baking dish.

Pour the egg and cream mixture over the top and gently mix to distribute.

Top with slices of provolone or sprinkle shredded cheese over the casserole.

Bake for 25–30 minutes, or until the cheese is melted and bubbly and the center is set.

Let it rest for 5 minutes before slicing and serving.
