Main Ingredients

  • 1 lb flank steak, sliced thin Slice across the grain for tenderness
  • 1 onion, thinly sliced
  • 1 bell pepper, thinly sliced Any color
  • 2 cloves garlic, minced
  • 8 oz mushrooms, sliced
  • 1 can cream of mushroom soup
  • 1 cup beef broth
  • 1 tbsp Worcestershire sauce
  • 8 oz egg noodles, cooked and drained
  • 1.5 cups provolone cheese, shredded or thinly sliced
  • Salt and pepper to taste

Instructions
 

Preparation

  • Preheat the oven to 350°F (175°C) and grease a 9x13-inch baking dish.
  • Season the thinly sliced flank steak lightly with salt and pepper.
  • Heat a large skillet over medium-high heat with a tablespoon of oil.
  • Add the steak in a single layer and cook until browned but not fully cooked through, about 2 minutes per side. Remove to a plate and set aside.

Cooking

  • In the same skillet, reduce heat to medium and add the sliced onion and bell pepper. Sauté until they begin to soften, about 5 minutes.
  • Add the minced garlic and sliced mushrooms. Continue to cook until the mushrooms release their juices and everything is tender, about 4–6 more minutes.
  • Stir in the can of cream of mushroom soup, beef broth, and Worcestershire sauce. Bring the sauce to a gentle simmer and taste; adjust seasoning with salt and pepper.
  • Fold in the cooked egg noodles, tossing to coat evenly in the sauce.
  • Return the browned steak to the skillet and mix gently so meat is distributed through the noodle mixture.
  • Transfer everything into the prepared baking dish and spread evenly.
  • Top with the shredded provolone cheese in an even layer.
  • Bake for 25–30 minutes, or until the casserole is bubbly and the cheese is melted and lightly golden.
  • Let rest for 5 minutes before serving so it sets slightly and slices hold together.

Notes

For flavor variations, boil the casserole for 1-2 minutes at the end. Use other cheeses like Swiss or Monterey Jack as a substitute for provolone.
