  • 1 teaspoon Steak Seasoning McCormick’s Montreal recommended

Instructions

  • Start by preheating your oven to 375 degrees Fahrenheit. It’s gonna finish the casserole with a yummy golden top.
  • Season your sliced steak with the steak seasoning, salt, and pepper. Don’t be shy, coat it well so it’s tasty.
  • Heat a large skillet on medium-high and brown your steak strips until they get a nice color. Then take ’em off the heat and set aside for now.
  • In the same skillet, toss in green peppers, mushrooms, onion, and garlic. Sauté 'em till veggies get kinda soft, about 5 to 7 minutes.
  • Turn the heat down low and mix in the cream cheese and Worcestershire sauce. Stir until everything’s combined smooth and melty.
  • Throw the cooked steak back into the skillet, mixing it with the creamy veggie mixture so flavors mingle.
  • Now, beat the eggs in a small bowl then fold ’em gently into your skillet combo. This helps it set up nice later.
  • Pour everything into a greased 9x13 casserole dish. Top with shredded parmesan and provolone pieces spread evenly.
  • Bake for 20 to 25 minutes. You want the top set and just a little golden brown like a perfect crust.
  • Let it cool a bit before serving so it holds together better. Get ready for some serious comfort in every bite.

Notes

Let sit for 5 minutes after baking to help it set before cutting. Store covered in fridge for up to 4 days, or freeze in portions for an easy meal later.
