- black pepper

What kind of meat to use in Philly Cheesesteak?
There are several options available, when it comes to what kind of beef to use in this Philly Cheesesteak Skillet: You can use any leftovers of steak that you have, or cook the beef, before adding the vegetables and cheese.
If I don’t have any prime rib leftovers, I’d usually cook skirt steak of sirloin, very thinly sliced (shaved) across the grain. To make the slicing process of a raw steak easier, quickly freeze the meat for 30-60 minutes, then slice. Firm meat is much easier to shave than soft, room temperature meat.
- Cooked Prime rib leftovers
- Thinly sliced Ribeye (pricey)
- flank steak
- Skirt steak
- Sirloin
- ground beef
- Cooked Roast Beef
- Boneless Beef Short Ribs

This recipe was so easy and delish ! & the best Keto Community anywhere I read it everyday , and I’m also grateful I found , it help me not only loose weight but also keep it off , hope it helps some others on here too !
This was a delicious, easy recipe that went together quickly. The whole family liked it. A great way to use leftover steak.
I followed the instructions and at the end of the meal, I noticed that my “optional seasonings” were still on the kitchen counter. The recipe never said when to use them! Should they be rubbed on the steak or added to the broth??
Delish!! My non-keto husband LOVED it too!! We will definitely make this again!
Thanks for the nice comment! Glad to hear this!
I made this tonight since I had leftover beef roast, my husband loved it! Great flavors and textures, topped with Italian cheese(what I had in the fridge) – quick, easy, tasty.
perfect!!!
Made this tonight w/ leftover roast and, WOW. Both DH & I loved it. Gr8 recipe to add to our LC/Keto WOE. Thx!
So good. I used left over smoked roast beef with au jus, instead of the beef broth. Then I topped it onto Caesar salad. I have quite often done a stir chicken with onion and peppers on top of Caesar salad, but this is a great variation. I used mixed old cheddar and mozzarella as that is the cheese I had. I will definitely be making this again.
I was wondering when to add the broth? I didn’t see it in the instructions. Also how many ounces is a serving? Thank you! Looks delicious!
Broth is optional, after you sautee the vegetables.
