Ingredients
  

For the Casserole
  • 1.5 pounds sirloin steak sliced into thin strips
  • 1 teaspoon Steak Seasoning McCormick's Montreal Steak Seasoning recommended
  • salt and pepper to taste
  • 1 cup green peppers sliced
  • 1 cup mushrooms
  • 1 cup onion chopped
  • 2 cloves garlic chopped
  • 2 oz cream cheese
  • 1 teaspoon worcestershire sauce
For the Topping
  • 2 eggs
  • 1/2 cup heavy whipping cream
  • 1/2 cup shredded parmesan reggiano cheese
  • 4-5 slices provolone cheese sliced into small pieces

Equipment

  • 9x13 baking dish
  • Meal prep containers
  • Skillet
  • Medium bowl

Method
 

  1. Preheat your oven to 350 degrees F (175 degrees C).
  2. Add the sirloin steak to a skillet over medium-high heat. Season the steak with steak seasoning, salt, and pepper. Cook for 2-3 minutes, flipping both sides of the steak until browned.
  3. Add the green peppers, onion, garlic, and mushrooms to the skillet with the steak. Cook until the vegetables are soft and the meat is no longer pink.
  4. Drain any excess fat from the skillet. This helps prevent a soupy casserole.
  5. Stir in the Worcestershire sauce and cream cheese. Cook until the cream cheese is melted.
  6. Remove the skillet from the heat.
  7. In a medium bowl, whisk together the eggs, shredded parmesan reggiano cheese, and heavy cream.
  8. Lightly grease an 8x11 or 9x9 inch baking dish. Pour the steak and vegetable mixture into the prepared baking dish.
  9. Drizzle the egg and cheese mixture evenly over the steak mixture. Top with the provolone cheese slices.
  10. Bake for 15-20 minutes, or until the cheese is bubbly and lightly golden. The casserole should be set.
  11. Let the casserole cool slightly before serving.
