1 cup beef broth – Adds moisture and intensifies beef flavor.

1 tablespoon olive oil (for sautéing) – Helps soften vegetables and develop flavor.

Step-by-Step Instructions

Preheat the Oven

Preheat your oven to 350°F (175°C) and lightly grease a baking dish with non-stick spray.

Sauté the Vegetables

Heat olive oil in a skillet over medium heat. Cook sliced onions and bell peppers for 5–7 minutes until softened and slightly caramelized.

Brown the Ground Beef

Add ground beef to the skillet and cook for 8–10 minutes, breaking it apart until fully browned. Drain excess fat if necessary.

Incorporate Garlic and Cream Cheese

Stir in minced garlic and cook for 30 seconds until fragrant. Add cream cheese and beef broth, stirring until fully melted and evenly combined.

Transfer and Top with Cheese

Pour the beef mixture into the prepared baking dish and spread evenly. Sprinkle shredded provolone or mozzarella over the top in an even layer.

Bake Until Bubbly

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

Rest Before Serving

Allow the casserole to rest for 5 minutes before serving to help it set slightly.

Recipe Notes & Tips

Drain Excess Grease – Prevents a greasy casserole and keeps flavors balanced.
Slice Vegetables Evenly – Ensures uniform cooking and consistent texture.
Use Freshly Shredded Cheese – Melts smoother than pre-shredded varieties.
Don’t Overbake – Remove once cheese is golden to maintain creamy interior.
Add Mushrooms (Optional) – Sautéed mushrooms add authentic Philly flavor.
Season Gradually – Taste before adding salt since cheese and broth contain sodium.
