Preheat your oven to 375°F (190°C).

In a large skillet, heat olive oil over medium heat. Add bell peppers, onion, and garlic. Cook until softened, about 5–7 minutes.

Add ground beef to the skillet. Cook until browned, breaking it up as it cooks. Drain any excess grease.

Stir in salt, pepper, onion powder, paprika, Worcestershire sauce, and cream cheese. Mix until cream cheese is melted and fully combined.

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

Spread the beef mixture evenly into a greased 9×13 baking dish. Pour the egg mixture over the top.

Sprinkle shredded provolone and mozzarella cheese over everything.

Bake uncovered for 25–30 minutes, or until the cheese is bubbly and lightly golden.

Let it rest for 5 minutes before slicing. Garnish with chopped parsley if desired.
