Main Ingredients

  • 1.5 lb Thinly Sliced Steak (such as ribeye or sirloin) Provides a rich and juicy foundation.
  • 1 medium Onion (sliced) Adds sweet and savory aroma.
  • 1 medium Green Bell Pepper (sliced) Brings crisp freshness and color.
  • 8 oz Cream Cheese (softened) Creates a creamy base.
  • 1 cup Mayonnaise Adds richness and subtle tang.
  • 1 tsp Garlic Powder Infuses a warm, garlicky undertone.
  • 0.5 tsp Salt Enhances flavor.
  • 0.25 tsp Black Pepper Adds heat.
  • 6 slices Provolone Cheese Melts beautifully for a cheesy finish.

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C).
  • In a large skillet over medium-high heat, add the thinly sliced steak. Cook until browned and just cooked through, about 3-5 minutes. Remove and set aside.
  • In the same skillet, add sliced onion and green bell pepper. Sauté for about 5 minutes, or until tender and slightly caramelized.
  • In a mixing bowl, combine softened cream cheese, mayonnaise, garlic powder, salt, and black pepper. Stir until smooth.
  • Add cooked steak back into the skillet with the sautéed onions and peppers. Mix thoroughly.
  • In a greased baking dish, spread half of the creamy mixture on the bottom. Add the steak and vegetable mixture, then spread the remaining creamy mixture on top.
  • Lay the provolone cheese slices over the top of the casserole.
  • Bake in the preheated oven for about 25-30 minutes until the cheese is bubbly and golden brown.
  • Let the casserole sit for a few minutes before serving.

Notes

Use high-quality steak for the best flavor. Leftovers can be stored in an airtight container for up to three days. Consider variations like adding mushrooms or using different cheeses.
