Instructions

Preheat your oven to 375°F (190°C).
In a large skillet, heat olive oil over medium heat. Add diced onions and bell peppers. Cook until softened, about 5 minutes.
Add garlic and cook for another minute.
Add the ground beef to the skillet and cook until browned, breaking it up as it cooks. Drain any excess grease.
Stir in cream cheese, sour cream, Worcestershire sauce, salt, pepper, and Italian seasoning (if using). Mix until creamy and well combined.
Transfer the mixture to a greased 9×13-inch casserole dish.
Top with shredded mozzarella and provolone cheese.
Bake for 20–25 minutes, or until the cheese is melted and bubbly.

Let cool slightly before serving. Serve as-is or with hoagie rolls if you want the sandwich vibe!

Notes

You can swap ground beef with thinly sliced steak for a more authentic taste.
Add mushrooms for extra flavor!

Make it low-carb by skipping the bread and serving with a side salad.
