  • 1.25 lbs shaved ribeye steak
  • 2 TB Avocado oil
  • 1 TB butter
  • 1/2 onion sliced
  • 1/2 red bell pepper sliced
  • 1/2 green bell pepper sliced
  • 1/2 cup mushrooms chopped
  • 2 garlic cloves minced
  • 1 TB beef broth
  • 1 tsp Worcestershire sauce
  • 1 tsp Braggs aminos
  • 1/2 tsp salt
  • 1/2 tsp pepper
  • 6 oz provolone cheese (about 9 slices)


  • Heat avocado oil in a cast-iron skillet on medium-high. (I used a 10 1/2" skillet.)
  • Season the steak with salt and pepper.
  • Sear the steak in two batches. (If you overcrowd the skillet you won’t get a good sear on the steak). When the steak is browned, remove from the skillet and set aside.
  • Add 1 tbsp butter to the same skillet along with peppers, onions, garlic, and mushrooms. Sauté until the veggies are softened.
  • Next add your beef broth, Braggs Aminos, Worcestershire sauce, and salt/pepper and cover with a lid. Simmer for 4 minutes.
  • Add steak back to the pan and cook on medium for two minutes.
  • Add provolone cheese on top of the casserole covering as much as possible. (See step-by-step images above.)
  • Place the skillet in the oven on broil for 1-3 minutes or until the provolone cheese begins to brown and bubble. Watch carefully as it can burn very quickly!


*Traditionally, a Philly Cheesesteak is made with thinly sliced ribeye. Ribeye steaks are pricier but the best meat to use. If you are on a budget, you can also use skirt steak or sirloin. Another meat option is to use ground beef! The flavors will still be there.

Don't have a cast-iron skillet?

If you don't have a cast-iron skillet, you can use a regular oven-safe skillet to do the same job. Another option is to prepare the veggies and steak as stated above. Then transfer everything to a small casserole dish (similar in size to a skillet) and layer with the provolone. Cover and refrigerate or freeze until your ready to reheat. Be careful about reheating since you do not want to overcook your steak!
