Philly Cheesesteak Casserole

This deconstructed cheesesteak is layered with egg noodles, a creamy steak and vegetable mixture, and topped with plenty of gooey cheese.

Prep Time: 20 minutes
Cook Time: 30 minutes
Yields: 6-8 servings

Ingredients

· 8 oz wide egg noodles
· 2 tablespoons olive oil
· 1 large yellow onion, thinly sliced
· 1 large green bell pepper, thinly sliced
· 8 oz mushrooms, sliced (optional, but classic)
· 2 cloves garlic, minced
· 1.5 lbs ribeye steak, thinly shaved (see note for easy slicing)
· 1 teaspoon Worcestershire sauce
· Salt and black pepper to taste
· 1 (10.5 oz) can cream of mushroom soup
· ½ cup beef broth
· ¼ cup sour cream
· 2 cups shredded provolone cheese (or a Provolone/Mozzarella blend)
· ½ cup shredded cheddar cheese (for extra color and sharpness)
· Chopped fresh parsley for garnish (optional)

Instructions

Step 1: Cook the Noodles & Veggies

  1. Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish.
  2. Cook the egg noodles according to package directions until al dente (they will cook more in the oven). Drain and set aside.
  3. While noodles cook, heat olive oil in a large skillet over medium-high heat. Add the sliced onion, bell pepper, and mushrooms (if using). Sauté for 6-8 minutes, until softened and lightly browned.
  4. Add the minced garlic and cook for 1 more minute until fragrant. Transfer the vegetable mixture to a bowl.

Step 2: Cook the Steak

  1. In the same skillet, add the thinly shaved steak. Season with salt, pepper, and Worcestershire sauce.
  2. Cook over medium-high heat, breaking it up with a spoon, until just browned. It will cook quickly. Do not overcook.
  3. Drain any excess liquid from the skillet.

Step 3: Create the Creamy Base

  1. In a small bowl, whisk together the cream of mushroom soup, beef broth, and sour cream until smooth.

Step 4: Assemble the Casserole

  1. In the prepared baking dish, combine the cooked egg noodles, sautéed vegetables, and browned steak. Toss to mix evenly.
  2. Pour the creamy soup mixture over everything and stir until well coated.
  3. Sprinkle the shredded provolone and cheddar cheeses evenly over the top.

Step 5: Bake

  1. Bake, uncovered, for 20-25 minutes, or until the casserole is hot and bubbly and the cheese is completely melted and golden in spots.
  2. For an extra-browned top, you can broil for the last 1-2 minutes (watch closely!).

Step 6: Serve

  1. Let the casserole rest for 5-10 minutes before serving. This allows it to set slightly.
  2. Garnish with fresh chopped parsley and serve immediately.

Chef’s Notes & Tips for Success

· The Secret to Thinly Sliced Steak: Getting the steak thin is crucial. Here are two easy methods:

  1. Freezer Trick: Place the steak in the freezer for 30-45 minutes until it’s firm but not solid. This makes it much easier to slice paper-thin.
  2. Ask Your Butcher: The easiest method! Simply ask your butcher to shave the ribeye for you on their deli slicer.
    · Steak Alternatives: Ribeye is traditional for its flavor and fat content, but shaved sirloin, flank steak, or even frozen sandwich steaks (like Steak-umm) work perfectly well in a casserole.
    · Amazing Flavor Boost: For a more “authentic” cheesesteak flavor, add a tablespoon of Italian seasoning to the vegetables as they sauté and a dash of garlic powder with the steak.
    · From-Scratch Sauce: If you prefer not to use canned soup, make a simple béchamel: Melt 3 tbsp butter, whisk in 3 tbsp flour, cook 1 minute. Whisk in 1 ½ cups milk and ½ cup beef broth until thickened. Season with salt, pepper, and a dash of Worcestershire sauce.
    · Make-Ahead: You can assemble the entire casserole (without baking) up to 24 hours in advance. Cover and refrigerate. Bake as directed, adding 5-10 minutes to the cooking time since it will be cold from the fridge.

Enjoy this hearty, cheesy, and incredibly satisfying meal
