What Is Philly Cheesesteak?

Philly cheesesteak has its roots in Philadelphia, Pennsylvania. It consists of thinly sliced steak, grilled onions, and melted cheese served in a hoagie (bread roll). The kind of cheese can range from mozzarella cheese to cheddar or provolone. Sliced bell peppers can also be added into the mix for extra flavor, but they’re not necessary. There are also regional and dietary variations of the recipe like my Cheesesteak Stuffed Mushrooms or Keto Cheesesteak Stuffed Peppers. Cheesesteaks are considered a fast-food dish that’s perfect for game-days.

Ingredients for philly cheesesteak skillet.

Recipe Ingredients

The fresher the veggies, the better your skillet will come out. Scroll to the recipe card at the bottom of the post for exact measurements.

  • Avocado oil – Feel free to use olive or coconut oil.
  • Baby bella mushrooms – Creminis are a great swap and so are button mushrooms.
  • Top sirloin – Make sure it’s center-cut.
  • Garlic cloves – You can use garlic powder instead.
  • Bell peppers – Use any color of bell peppers for this.
  • Sweet onion – White onion works too.
  • Salt and pepper – I prefer kosher salt and freshly-cracked pepper.
  • Parmesan cheese – Freshly-grated cheese is best. Avoid the kind in a green bottle.
  • Mozzarella cheese – Buy it pre-shredded or shred it yourself.

How to Make a Philly Cheesesteak Skillet

The key’s in cooking all the veggies until tender to avoid a raw after-taste. Scroll to the recipe card at the bottom of the post for more detailed instructions.

  • Cook the mushrooms. Add 1 tablespoon oil to a large skillet over medium-high heat. Stir in the mushrooms and sauté them for 3-6 minutes or until browned. Season them with salt and pepper. Remove them from the heat and set aside.
  • Sear the steak. Add 1 tablespoon oil to the skillet. Arrange the beef in a single layer. Sear it for 2-3 minutes on each side or until browned. Remove it from the heat and set it aside with the mushrooms.
  • Cook the peppers. Toss in the garlic, bell peppers, and onions. Mix well and cook everything for another 4-5 minutes or until the onions soften.
  • Combine everything. Return the mushrooms and steak into the skillet. Stir well.
  • Make it melty. Sprinkle parmesan and mozzarella cheese on top. Reduce the heat to medium. Cover the skillet and cook for 2-3 minutes or until nice and melty.
  • Serve it. Remove the skillet from the heat and serve immediately. Enjoy!

Tips and Variation Ideas

From cooking in batches to stuffing peppers, these tips will help you go above and beyond with this philly cheesesteak skillet.

  • Use frozen fajitas. If your local grocery store carries frozen beef fajitas, go ahead and use them to cut down on prep time. Make sure they’re completely thawed, though.
  • Swap the protein. Turkey and chicken make great swaps for beef in this recipe.
  • Use leftovers. Shred all the leftover bits of melty cheese in your fridge for a unique cheese-blend and replacement for mozzarella.
  • Add more veggies. Sauteed spinach, zucchini, and sweet potatoes can make this dish extra hearty.
  • Cook in batches. To get a nice sear on the steak, you need to avoid over-crowding the pan. If you don’t have a large enough pan to cook in, do it in batches.
  • Stuff some peppers. Cut the top off whole bell peppers. Remove the seeds. Stuff the peppers with the cheesesteak mixture. Shred more cheese on top. Bake them at 350F for 20-25 minutes or until the peppers are tender.
  • Make it spicy. Finely chop jalapeños or serranos and stir them into the mixture for a kick of heat. You can also use red pepper flakes.

How to Store and Reheat Extras

The leftovers need to be fully cooled before refrigerating.

  • Fridge: Place it in an airtight container for up to 5 days.
  • To reheat it: Microwave it in 30-second increments until warm and melty again. You can also reheat it in a pan over medium-high heat for 7-9 minutes, stirring occasionally.
