Where did the Philly Cheesesteak come from?

The idea of this popular sandwich dates back to 1930 from a man named Pat Olivieri. He ran a hot dog stand in Philly and was getting bored of his “same old, same old” – so one day he decided to grill up some beef scraps and put them into an Italian roll. A cabbie who was on his daily route, stopped because of the delicious smell coming from Pat’s stand. He tried it and told Pat to ditch the hot dog concept and start selling these instead! That’s when the Philly Cheesesteak legend was born! Pretty interesting stuff!

The OG sandwich actually didn’t have any cheese at all. It wasn’t until the 1950’s that a manager at Pat’s restaurant – they called him “Cocky Joe,” decided to add provolone to the sammy! The sandwich became extremely popular in the 1960’s when “Geno’s Steaks” opened across the street from Pat’s restaurant! (Pretty bold!) A little healthy competition never hurt anyone, right? From there – several others followed suit locally and each little spot had their own unique customer base!

Today, the concept of the Philly Cheesesteak is enjoyed all over America taking on a different spin according to its maker. You can find soups, casseroles, and even dips using these inspirational flavors originally crafted by Pat and his team!

Okay, so what ingredients do I need to make this?

For the Philly Cheesesteak Casserole:

Beef Shaved Steak
Provolone Cheese
Bell Pepper
Onion
Garlic
Mushroom
Cream of Mushroom
Butter
Olive Oil
Salt
Black Pepper
Oregano
Cayenne
Breadcrumbs

For serving:

Parsley

Equipment Needed:

• Cutting Board
• Chef Knife
• Paring Knife
• Baking Pan
• Large Skillet
• Wooden Spoon
• Measuring Cups and Spoons

How do I make it?

To prep the ingredients:

Wash and prep all of your veggies! Thinly slice the peppers. Dice the onion. Slice the mushrooms and mince the garlic.

Preheat oven to 375 F and lightly grease a 9×9 baking dish.

To make the Philly Cheesesteak Casserole:

Next, in a large skillet, heat the oil on medium and start cooking the steak. When the steak is about halfway done and still a little pink, add in all the veggies, some of the butter, and seasonings, then cook a few minutes longer, stirring occasionally.

Turn heat to low and stir in the cream of mushroom soup. Heat a minute or so until everything is well incorporated, then dump into prepared baking dish.

Next, lay out the provolone in even rows along the top of the casserole. Melt remaining butter in a small dish and add in the breadcrumbs, stirring to combine.

Sprinkle the breadcrumb mixture over the Philly Cheesesteak Casserole and bake until the cheese is melted and bubbly!

To serve:

Broil on high for a few minutes until golden, then garnish with parsley, if desired! Serve hot and enjoy!

Tips:

• If you don’t want to use pre-shaved steak, you could use a skirt steak or flank steak and slice it very thin yourself!
• This recipe did have a kick, but it was still family friendly! The cayenne gave it that little extra cheesesteak flavor I was looking for, but you could omit it if you’d like.
• If you want to stretch this dish even further, consider boiling some pasta and spooning the baked casserole over the top!
