Ingredients

  • 1.5-2 pounds Flank Steak
  • 1 teaspoon Paprika
  • 1 teaspoon Salt
  • 1 teaspoon Ground black pepper
  • 1 tablespoon Olive Oil
  • 1 Yellow onion, medium
  • 1 Green or Red bell pepper I used green
  • 2 cloves Garlic, minced
  • ¾ cup beef broth
  • ½ cup Cream Cheese
  • 1 tablespoon Worcestershire Sauce
  • 4-6 slices Provolone Cheese (to cover the top of casserole) (or mozzarella)
  • 1 cups Shredded Cheddar (divided)
  • 2 Hoagie rolls or large sandwich buns (extra if you are making sandwiches)

Instructions

Prep-Ahead Steps

  1. Thinly slice the onions and bell peppers. Mince the garlic. Cut or tear the bread rolls into bite-size pieces.

  2. Slice the raw flank steak into thin strips going across the grain (the lines in the meat). Add the slices to a container large enough to toss the meat in the seasonings.

Cooking Steps

  1. Preheat a skillet over medium-high heat.

  2. Cook the steak slices in 2 batches so as not to overcrowd and steam it. Add a tablespoon olive oil to the hot pan and then the flank steak in a single layer and let sear for 2 minutes. Then stir to flip the steak slices and let the other side brown for 1 minute. Transfer the steak to the casserole pan leaving the fat and juices behind. Repeat until all of the steak is browned and in the casserole dish.

  3. To the same pan used for the steak, turn the heat down to medium-low and add the onions and the peppers. Let them get brown, stirring halfway through, for about 5 minutes, then transfer them to the dish with the steak. Then add the beef broth to the pan and scrape up all of the browned bits from the bottom. Add the minced garlic, worcestershire sauce and the cream cheese to the pan to melt. Stir until smooth then turn off the heat.

  4. Pour the sauce into the casserole dish stir to combine the sauce, meat and the onions and peppers. Sprinkle ½ of the shredded cheese over top and mix everything together.

  5. Now add slices of provolone or mozzarella over the meat mixture. Then cover with the cubed or torn bread pieces. Sprinkle the remaining shredded cheese over the bread. Place the entire casserole in the oven for 10-15 minutes at 400 F degrees until the cheese melts and and the top of the bread and cheese starts to get golden brown.

  6. If you are making Philly Cheesesteak sandwiches, warm or toast the hoagie rolls or sandwich buns in the oven. Fill the rolls with the meat mixture and enjoy!
