Ingredients

2 pounds shaved steak

Salt and pepper, to taste

1 tablespoon avocado oil

1 chopped onion

1 bell pepper, sliced into ½-inch strips (red, green, or yellow)

1 teaspoon garlic powder

1 tablespoon butter

¾ cup beef broth

4 ounces cream cheese, cubed

16 ounces grated provolone, divided


Instructions

  1. Preheat oven to 350°F (175°C). Season steak with salt and pepper.
  2. Heat avocado oil in a large skillet over medium-high heat. Add steak and cook until browned, about 2 minutes per side. Remove from heat, let cool slightly, and chop.
  3. In the same skillet, sauté onion and bell pepper for 6 minutes until softened. Add garlic powder, salt, and pepper. Mix in chopped steak and remove from heat.
  4. Melt butter in a saucepan, add beef broth, and bring to a simmer. Reduce heat, add cream cheese, and whisk until smooth. Reduce to low heat and stir in half of the provolone until melted.
  5. Pour cheese sauce over steak and vegetables, stirring to combine. Transfer to a casserole dish and top with remaining provolone.
  6. Bake for 25–30 minutes until bubbly and golden. Optional: broil 1–2 minutes for a crispier top.
