Ingredients
  

For the Casserole
  • 1.5 pounds sirloin steak sliced into thin strips
  • 1 teaspoon Steak Seasoning McCormick's Montreal Steak Seasoning recommended
  • to taste salt and pepper
  • 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 Fahrenheit.
  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.
  3. Add the green peppers, onion, garlic, and mushrooms to the skillet. Cook until the vegetables are soft and the meat is no longer pink.
  4. Drain any excess fat from the skillet. This step prevents a soupy casserole.
  5. Add the Worcestershire sauce and cream cheese. Cook until the cream cheese has melted.
  6. Remove the skillet from heat.
  7. In a medium bowl, combine the eggs, shredded parmesan reggiano cheese, and heavy cream.
  8. Spray an 8x11 or 9x9 baking dish with oil or cooking spray. Pour the steak and vegetable mixture into the dish.
  9. Drizzle the egg and cheese mixture over the steak mixture. Top with the provolone cheese slices.
  10. Bake for 15-20 minutes, or until the cheese begins to bubble. The casserole is typically ready around 18 minutes.
  11. Let the casserole cool before serving.
