Watch the video above for step by step instructions.
-
Preheat oven to 350 degrees.
-
Add the Butcher Box steak to a skillet on medium-high heat. Season the steak with steak seasoning, salt, and pepper. Cook for 2-3 minutes, flipping both sides of the steak.
-
Add the green peppers, onion, garlic, and mushroom to the skillet. Cook until the vegetables are soft and the meat is no longer pink.
-
If there is any excess fat in the skillet, drain it. This step is important. If there is excess liquid it will cause the casserole to have a soupy residue underneath.
-
Add the Worcestershire sauce and cream cheese. Cook until the cream cheese has melted.
-
Remove the skillet from heat.
-
In a medium bowl, combine the eggs, shredded parmesan reggiano cheese, and heavy cream.
-
Spray an 8 x 11 or 9×9 baking dish (I used 8 x11) with oil or cooking spray. Pour the steak mixture into the dish.
-
Drizzle the liquid egg and cheese mixture on top. Top with the provolone cheese slices.
-
Bake for 15-20 minutes or until the cheese begins to bubble. Mine was ready around 18.
-
Cool before serving.
