Ingredients
  

Main Ingredients
  • 1 pound ground beef (or steak strips)
  • 1 tablespoon olive oil
  • 1 medium onion, chopped
  • 1 each green bell pepper, sliced
  • 1 each red bell pepper, sliced
  • 3 cloves garlic, minced
  • 1 teaspoon salt
  • 0.5 teaspoon black pepper
  • 1 teaspoon smoked paprika
  • 1 cup heavy cream
  • 1 cup cream cheese, softened
  • 2 cups shredded provolone cheese (or cheese of choice)
  • Fresh parsley for garnish (optional)

Method
 

Preparation
  1. Preheat the oven to 350°F (175°C).
  2. Heat olive oil in a large skillet over medium-high heat. Add the ground beef (or steak strips) and cook until browned, breaking it up with a spatula if using ground beef.
  3. Add the onions and cook for about 3-4 minutes until they become translucent.
  4. Incorporate the bell peppers and garlic, cooking until the peppers are tender and the garlic is fragrant, about 5 minutes.
  5. Season the mixture with salt, black pepper, and smoked paprika, stirring to combine. Remove the skillet from heat and set aside.
  6. In a mixing bowl, combine the heavy cream and softened cream cheese. Whisk until smooth.
  7. Add half of the shredded cheese to the cream mixture and stir until fully incorporated.
  8. Combine the steak mixture with the cream mixture, ensuring everything is evenly coated.
  9. Pour the mixture into a greased baking dish, spreading it evenly.
  10. Top with the remaining shredded cheese.
  11. Bake in the preheated oven for about 25-30 minutes or until the cheese is melted and bubbly.
  12. Remove from the oven and let it cool for a few minutes before garnishing with fresh parsley, if desired.
