Recipe Steps:

  1. Preheat Oven and Prepare Ingredients: Set your oven to 350°F (175°C). Lightly grease a casserole dish.
  2. Cook the Beef: In a skillet, cook the sliced beef over medium-high heat until browned. Remove and set aside.
  3. Sauté Vegetables: In the same skillet, add a bit more oil and sauté the onions and bell peppers until tender.
  4. Prepare Bread Base: Cut hoagie rolls into cubes and lay them in the bottom of the casserole dish, creating a bed for the toppings.
  5. Layer the Casserole: Spread the cooked beef over the bread cubes, then layer the sautéed onions and peppers. Top with slices or shredded Provolone cheese.
  6. Bake: Cover with foil and bake in the preheated oven for about 20 minutes, then uncover and bake for an additional 10 minutes or until the cheese is bubbly and golden.
  7. Serve: Allow to cool slightly before serving to let the layers set up for easy slicing.

Storage Options:

  • Refrigerate: Keep leftovers in an airtight container in the fridge for up to 3 days.
  • Reheat: Best reheated in the oven to maintain the textures, though a microwave will work in a pinch.


  • 1 pound ribeye steak, thinly sliced
  • 2 tablespoons olive oil
  • 1 large onion, sliced
  • 1 green bell pepper, sliced
  • 1 red bell pepper, sliced
  • 2 cloves garlic, minced
  • Salt and pepper, to taste
  • 1 teaspoon Worcestershire sauce
  • 6 ounces provolone cheese, sliced or shredded
  • 4 large eggs
  • 1 cup milk
  • 1/2 cup heavy cream
  • 1/2 teaspoon paprika
  • Optional: sliced mushrooms, sautéed


  1. Preheat the Oven and Prepare the Ingredients:
    • Preheat your oven to 350°F (175°C).
    • If the steak isn’t already thinly sliced, place it in the freezer for about 30 minutes to firm up, which makes slicing easier. Slice the steak into thin strips.
  2. Cook the Steak and Vegetables:
    • Heat olive oil in a large skillet over medium-high heat. Add the sliced steak and cook until browned, about 3-4 minutes. Remove the steak from the skillet and set aside.
    • In the same skillet, add the onions, bell peppers, and garlic. Season with salt and pepper. Cook until the vegetables are softened, about 5-7 minutes. Add the Worcestershire sauce and stir to combine.
  3. Combine Steak and Vegetables:
    • Return the cooked steak to the skillet with the vegetables and mix well. If using, add the sautéed mushrooms.
  4. Prepare the Egg Mixture:
    • In a bowl, whisk together the eggs, milk, heavy cream, and paprika.
  5. Assemble the Casserole:
    • Spread the steak and vegetable mixture evenly in a greased 9×13 inch baking dish.
    • Layer the provolone cheese over the steak and vegetables.
    • Pour the egg mixture evenly over the cheese.
  6. Bake:
    • Bake in the preheated oven for 25-30 minutes, or until the egg mixture is set and the top is lightly browned.
  7. Serve:
    • Let the casserole cool for a few minutes before slicing. Serve hot.
