1. Preheat & Prepare
Preheat your oven to 375°F (190°C) and grease a 9×13-inch baking dish to prevent sticking.
2. Cook the Beef
In a large skillet over medium-high heat, cook the ground beef (or steak with olive oil) until browned. Drain any excess fat.
3. Sauté the Vegetables
Add the onions, bell peppers, mushrooms (if using), and garlic to the skillet. Cook until softened, about 5 minutes. Stir in Worcestershire sauce, salt, pepper, and Italian seasoning.
4. Mix in the Cream Cheese
Reduce heat to low and stir in softened cream cheese until fully melted and combined. Remove from heat.
5. Prepare the Egg Mixture
In a mixing bowl, whisk together eggs and heavy cream. Stir in the shredded cheese.
6. Assemble the Casserole
Spread the beef mixture evenly into the prepared baking dish. Pour the egg mixture over the top and gently stir to distribute.
7. Top with Cheese & Bake
Lay slices of provolone cheese over the casserole. Bake for 25-30 minutes, or until the cheese is golden and bubbly.
8. Serve & Enjoy
Let the casserole cool for a few minutes before slicing. Serve hot and enjoy!
