    How to Make Philly Cheesesteak Casserole

    Slice steak, across the grain, into thin slices. Heat a large oven-safe skillet to medium and add in the olive oil, steak, salt and pepper.

    Tip: If you're having trouble slicing the steak, stick it in the freezer for about 45 minutes. This will firm up the steak making it slice much easier.

    Sauté for 1-2 minutes, then remove, drain and set aside.

    Preheat oven to 375°F.

    Add in the butter, peppers, onions and mushrooms, then sauté until they’re tender. 

    Tip: In a crunch for time? Slice the meat, peppers and onions the night before and store them in the fridge in an airtight container or freezer bag.

    Stir in the cream cheese, Worcestershire, parsley and shredded Italian cheese blend.  Once melted, add the steak back into the pan and stir to combine. Top with the provolone cheese, making sure all areas of the pan are covered.

    Bake for 15-17 minutes or until the cheese has melted and is slightly golden.

    What Cut of Meat is Best for Philly Cheesesteak?

    A delicious Philly cheesesteak's star ingredient is steak, so deciding what cut beef you should use is the first step. But no worries, there are some surprising ways to make this steak recipe fit any budget!

    • Ribeye: This cut of beef is usually going to be the priciest, next to filets. It has the most marbling and flavor. If you find them on sale, grab several and freeze for later.
    • New York Strip: This is my personal favorite for making this Philly cheesesteak casserole. It has really nice marbling and flavor, but on average costs several dollars less per pound than ribeye steak.
    • Sirloin: Sirloins are typically leaner cuts of beef coming from the top of the cow's back. Because there's not a whole lot of extra fat in sirloin steak, you may not want to cook it quite as long, to keep it from drying out. When seasoned correctly, it's a wonderful option.

    • Flank or Skirt Steak: Both of these type steaks are certainly more affordable than others, but they can be tough and chewy. To help them stay tender, you'll want to freeze them for about an hour before you start this recipe. Then cut across the grain into super thin slices, almost as though you're shaving it. When you cut them this thin, they won't take as long to cook.
    • Ground Beef: Some Philly cheesesteak shops would flip over this suggestion. But let me tell you, there is nothing wrong with using ground beef in this casserole, especially grass-fed beef. It's tender, flavorful, and it soaks up the juices well. Plus, you can almost always find it on sale somewhere.
    • Deli Roast Beef: This is a really quick way to prepare this casserole. If you want to use deli roast beef slices, no cooking is involved, be sure to get as rare as possible. Just sauté the veggies and make the cream sauce. Add the cooked deli roast beef right before you top it with cheese and place it in the oven.

    How Many Carbs are in a Philly Cheesesteak Without Bread?

    I love a soft warm hoagie bun as much as anyone else, but did you know that for the average hoagie bun, there are around 33 grams of carbs...each!? The good news is the steak, cheese and veggies used to make a Philly cheesesteak sandwich can be just as tasty without the bun.

    What is the Secret to a Good Philly Cheesesteak?

    Tender beef and gooey cheese! Those are truly what makes the very best Philly cheesesteak. Make sure to season the beef and use a flavorful sauce like Worcestershire sauce or steak sauce to enhance the flavor.

    When selecting a cheese, you want a good melty cheese like the provolone cheese, cheddar or mozzarella.

    If you love this combination of flavors, check out these philly cheesesteak stuffed peppers! They're beefy, cheesy and made in less than an hour!

    What Sauce is Good on Philly Cheesesteak?

    You can use any kind of sauce that you would typically use on a steak. For this casserole, you'll use a homemade sauce made using beef broth, tangy cream cheese and Worcestershire sauce. It has an excellent combination of flavors that truly enhances the beef and veggies without overpowering them.

      This recipe was fantastic! I used "beef for carne picada" which is something they have where I live at the grocery stores. It's thinly sliced Chuck Roast. It turned out so tender and delicious, I barely even missed the hoagie roll! Thought I'd drop a comment for anyone else looking for a cheap, quick cut of meat to use for this recipe. God bless!

        That sounds like a great choice! I love hearing how you made the recipe work with what’s available near you. Using carne picada is such a smart swap and it must have made the casserole extra tender and flavorful. Thanks so much for sharing, I’m sure it’ll help others looking for an easy and budget-friendly option. So glad you enjoyed it!

        I have read several comments from you about how you speak about all the different food sensitivities you work with. Without knowing what you can and can't tolerate, I am not sure what to recommend in place of the peppers. Maybe just try omitting them.

      I have made this several times. It always comes out so good. My kids said it was the best steak and cheese they have ever eaten. I have a meat slicer at home so I usually buy a cheap roast of some sort and slice it myself. Wow, so easy and delicious! I doubled it and they love the leftovers.

      This was delicious. I had a small chuck roast on hand so I seasoned it with salt, pepper, garlic powder, and onion powder, browned it on all sides and cooked it on low for 6 hours with the beef broth and some butter in the crockpot. When I was ready I shredded the beef and added it and the broth from the crock pot to the pan did everything else per your recipe, it was awesome!
