Cheesesteak sandwich are a quick and easy dinner to get on the table in under 30 minutes. Thinly sliced London broil is sautéed with onion, mushrooms, and provolone cheese for a delicious dinner.

Cheesesteak sandwiches are one of my go to dinners when I need something quick and easy. More often than I not, I use leftover steak to make the cheesesteaks. But I sometimes use fresh steak, too. From start to finish, you can have the sandwiches on the table ready to eat in under 30 minutes.
These are not true, authentic “Philly” cheesesteak sandwiches. In order to have an authentic Philly style cheesesteak, you would need very thinly sliced cheesesteak meat and some form of Pasteurized Process Cheese Food.
Instead, this is a slight healthier cheesesteak sandwich that uses steak meat anyone can find in the store and real, natural Sargento® Sliced Cheese.
Easy Cheesesteak Sandwich Recipe
To make cheesesteaks, you need onions, mushrooms, steak and cheese. For the meat I used a London broil steak. I’ve also used sirloin in the past. Both turn out great and you can usually find them on sale for a reasonable price.
The cheese usually used to make cheesesteaks is some form of Pasteurized Process Cheese Food (PPCF), sometimes known as American singles. It is only required to contain 51% real cheese. If you prefer your cheese to be real you can use sliced cheese, too.
You can use any cheese you like in a cheesesteak but white American is traditional. Provolone is great because it has a mild flavor. Cheddar would work well and Pepper Jack would make nice spicy cheesesteak sandwiches.
To make the cheesesteak filling, begin by sautéing the onions and mushrooms until the mushrooms release juices. You can also add in green peppers, if you like.
Add in the sliced steak and season with salt and pepper. Make sure to slice the steak as thin as possible. Leave the steak just slightly still frozen to help get it thin. You want it almost shaved thin.
The steak should take about 2 minutes to cook because it’s thinly sliced.
Once the steak is cooked, add in the cheese of your choosing. Stir the mixture to melt the cheese. It will be a gooey, cheesy, delicious mess once it’s done. You may need to turn the heat up to get the cheese to melt and cover all the meat. Cook long enough to get the cheese bubbling.
Once the cheese is melted, use tongs to scoop the meat mixture out and serve on a sub sandwich roll. The cheese combines with the juices from the steak and mushrooms to create an amazing cheesy sauce. You can also add a topping of marinara sauce, which is my favorite way to eat a cheesesteak sandwich.
