Philly Cheesesteak Ingredients

  • Skirt or Flank Steak: You’ll need about 1 ½ pounds, cut against the grain into thin slices.
  • Olive Oil: this is for sautéing, so use a medium- to light- olive oil rather than a virgin oil.
  • Onion: You’ll need a small yellow onion, thinly sliced.
  • Fresh Garlic: Mince or put through a garlic press.
  • Bell Peppers: Thinly sliced.
  • Crimini (Baby Bella) Mushrooms: I like to get mine pre-sliced, but you can slice your own. You can also substitute button mushrooms or shiitake.
  • Sliced Provolone: I like the smoked Provolone, but plain is fine, as well.

Cooking Your Low-Carb Skillet Philly Cheesesteak

  1. Season and Cook the Steak: Season the steak well with salt and freshly ground black pepper. Heat oil in a large skillet (cast iron skillet is good, but regular is fine, too). Saute the steak for 1-2 minutes per side. To avoid crowding the pan, you may have to work in batches. Remove the steak to a plate and set aside.
  2. Season and Cook the Vegetables: Drain off any liquid from the pan; heat the remaining oil, and add the vegetables, garlic, and Italian Seasoning. Cook until the veggies are soft.
  3. Return Steak to Pan and Top with Cheese: Add the cooked steak back to the pan and continue cooking for a minute to heat through. Taste for salt, and then place sliced Provolone on top of the mixture. Allow the cheese to melt.
  4. Garnish and Serve: Sprinkle the chopped parsley and green onions over the dish. Enjoy!

Tips For Success

  • Choose the best steak: For a dish like this, you want steak with a reasonable fat content (marbling), sliced very thinly against the grain. Feel free to ask your butcher to do it for you!
  • Substitutions: If you can’t find orange and green bell peppers, feel free to use two of the same color, or just substitute red and/or yellow bell peppers. Also, you can experiment with using Muenster or Swiss cheese instead of Provolone.
  • Not cutting carbs? If you aren’t worried about carbs, feel free to load this cheesesteak mixture on to your favorite sandwich rolls, or serve it over steamed rice!

Storing Leftovers

  • Refrigerate leftovers in tightly-covered containers, or in individual portions sealed in plastic food-storage bags, for up to 3 days. It’s not recommended to freeze this dish, as the texture of the ingredients will degrade in the freezer.
  • To reheat, cook in a covered skillet over medium heat for 5 minutes, or until heated through. Do not overcook.

  • Season steak with salt and pepper.
  • Heat 1.5 tablespoons olive oil in a large (12 to 14-inch) skillet set over medium-high heat.
  • Add sliced steak to the hot oil and cook for 1 to 2 minutes per side. You may want to do this in batches so that the steak browns and crisps up nicely. If the pan is overcrowded, it will steam the steak.
  • Remove cooked steak from pan and set aside; keep covered.
  • Drain any liquid from the pan and wipe it down.
  • Add remaining olive oil and heat it up over medium-high heat.
  • To the hot oil, add onions, garlic, bell peppers, mushrooms, and Italian Seasoning. Cook for 4 minutes, or until vegetables are soft. Stirring occasionally.
  • Stir steak back into the skillet and give it a minute to heat through.
  • Top mixture with cheese slices; lower heat to medium low, and continue to cook until cheese is melted. You can also pop it under the broiler to get a bit of browning on the cheese.
  • Remove from heat.
  • Garnish with green onions and parsley, and serve.


  • Quality Steak: Opt for a steak with a decent marbling, cut thin against the grain. If unsure, your butcher can always assist.
  • Make It Yours: Can’t find orange and green bell peppers? Red and yellow make great substitutes. Similarly, Muenster or Swiss cheese can replace Provolone.
  • Not on a Carb Watch?: Serve this cheesesteak mix on your favorite sandwich bread.
  • A cast iron skillet works great with this recipe.

    Not sure where you got your information from, however, Philly Cheese steaks are made from shaved beef, not flank or skirt steak. We use American cheese, not provolone. FYI

    There is a Facebook page lifting your recipe pictures and passing them along as her healthy meal plan. She’s a scammer and grifter and up to her next theft.
