How to make Steak Casserole

Making a delicious steak casserole is easy and satisfying. This dish combines tender steak with fresh vegetables and creamy cheese, resulting in a hearty meal perfect for any day of the week. Here’s how to bring this comforting dish to life.

Ingredients

  • 1 1/2 pounds Butcher Box sirloin steak (sliced into thin strips)
  • 1 teaspoon Steak Seasoning (I like McCormick’s Montreal Steak Seasoning)
  • Salt and pepper to taste
  • 1 cup sliced green peppers
  • 1 cup mushrooms
  • 1 cup onion, chopped
  • 2 garlic cloves, chopped
  • 2 oz cream cheese
  • 1 teaspoon Worcestershire sauce
  • 2 eggs
  • 1/2 cup heavy whipping cream
  • 1/2 cup shredded parmesan reggiano cheese
  • 4-5 slices provolone cheese (sliced into small pieces)

Directions

  1. Preheat your oven to 350 degrees.
  2. Cook the steak: Add the Butcher Box steak to a skillet on medium-high heat. Season the steak with steak seasoning, salt, and pepper. Cook for 2-3 minutes, flipping both sides of the steak until it’s nicely browned.
  3. Add the vegetables: Next, add the green peppers, onion, garlic, and mushrooms to the skillet. Cook everything together until the vegetables are soft and the steak is no longer pink in the middle.
  4. Drain excess fat: If you notice any excess fat in the skillet, drain it carefully.
  5. Add flavorings: Stir in the Worcestershire sauce and cream cheese. Cook until the cream cheese has melted and is well mixed with the steak and vegetables.
  6. Remove from heat: Once the mixture is well combined, take the skillet off the heat.
  7. Prepare the egg mixture: In a medium bowl, combine the eggs, shredded parmesan reggiano cheese, and heavy cream. Whisk until smooth.
  8. Prepare the baking dish: Spray an 8 x 11 or 9 x 9 baking dish with oil or cooking spray to prevent sticking. Pour the steak mixture into the dish.
  9. Add the egg mixture: Drizzle the liquid egg and cheese mixture on top of the steak and vegetables.
  10. Top with cheese: Finally, layer the provolone cheese slices over the top.
  11. Bake: Place the dish in the preheated oven and bake for 15-20 minutes, or until the cheese begins to bubble and turn golden.
  12. Cool before serving: Let the casserole cool for a few minutes before serving.
