Ingredients

  • 1 cup roughly 115 grams of grated provolone cheese
  • 1/2 teaspoon of ground black pepper
  • 2 garlic cloves finely chopped
  • 1 cup about 115 grams of shredded mozzarella
  • 8 ounces approximately 225 grams of softened cream cheese
  • 1 teaspoon of Worcestershire sauce
  • 1 tablespoon of extra virgin olive oil
  • 1 red bell pepper finely chopped
  • 1 medium onion diced
  • 1 teaspoon dried oregano
  • 1 green bell pepper chopped
  • 8 ounces 225 grams of white mushrooms, thinly sliced
  • 1/2 cup 120 ml of beef stock
  • 1 teaspoon of salt or to preference
  • 1 pound 450 grams of ground beef or shaved steak
  • Optional: freshly minced parsley for garnish

Instructions

  • Preheat your oven to 375°F (190°C).
  • Warm olive oil in a large skillet set over medium-high heat. Add the ground beef and cook until no longer pink, using a spoon to crumble the meat as it browns. Drain any extra fat as needed.
  • Incorporate the onion, both bell peppers, and sliced mushrooms into the skillet. Sauté for 5 to 6 minutes, stirring occasionally, until the vegetables are softened. Add minced garlic and cook for an additional minute.
  • Season the mixture with salt, pepper, and Worcestershire sauce. Pour in the beef broth and allow the contents to simmer for 2 to 3 minutes.
  • Reduce heat to low and stir in the cream cheese, blending until the mixture is smooth and fully integrated with the meat and vegetables.
  • Transfer the combined mixture into a greased 9×13-inch baking dish. Scatter the shredded mozzarella and provolone cheeses across the top, followed by a light sprinkle of oregano.
  • Place the dish uncovered in the oven and bake for 15 to 20 minutes, or until the cheese topping is melted and bubbling at the edges.
  • Top with fresh parsley if using, and serve immediately alongside crusty bread, over rice, or with your choice of side.
