Low Carb Philly Cheesesteak Casserole

I have really been craving the flavors of a Cheesesteak lately. I got the idea of doing a spin off of a Philly Cheesesteak after seeing Peace Love and Low Carb’s Stuffed Philly Cheesesteak Peppers. For my family, the idea of a casserole just works better for some meals.

I decided to try my hand at making a Low Carb Philly Cheesesteak Casserole.

We don’t normally shop at Walmart… but we found ourselves there on a Friday night after going to Hobby Lobby (they are right  next to each other). I was wanting to make something quick for dinner that I could throw together without much fuss.

Sliced Beef Options for Low Carb Philly Cheesesteak 

I looked at Walmart’s options of sliced Beef in their main deli section, and I just wasn’t impressed at all. Lots of caramel coloring, soy, nitrates… ingredients that I wasn’t very happy about.

Adam said that maybe we should just buy a steak and cut it up as thinly as possible (another option, but more hassle than I wanted to deal with). As we were walking to get the steak, I looked and saw Hormel’s All Natural Sliced deli meats. I remembered that my sister had bought some Hormel All Natural Turkey for making sandwiches, because the ingredients were okay.

I’m sure that these deli meats aren’t perfect (and aren’t grass-fed ; ) ), but sometimes you do what you can. The sliced beef worked great in this recipe. You can always use your favorite sliced beef as a substitute. I know Kroger’s sells Boar’s Head brand that is all natural as well.

What is the best beef for Philly Cheesesteak Casserole?

The best beef to use for a Philly cheesesteak casserole is typically thinly sliced ribeye steak. Ribeye steak is known for its rich flavor and tenderness, making it ideal for this dish. However, if ribeye steak is not readily available or if you prefer a leaner option, you can also use thinly sliced sirloin steak or flank steak.

When selecting beef for your Philly cheesesteak casserole, look for cuts that are well-marbled and thinly sliced. This will ensure that the beef cooks quickly and evenly, and that it remains tender and juicy in the casserole.

Additionally, you can customize the beef selection based on your personal preferences and dietary needs. For example, if you prefer a leaner cut of meat, you can opt for sirloin steak or flank steak. If you’re following a specific diet, such as keto or low-carb, you can choose a fattier cut like ribeye steak for added flavor and richness.

Ultimately, the choice of beef will depend on your taste preferences and availability, but thinly sliced ribeye steak is generally considered the classic and most flavorful option for a Philly cheesesteak casserole.

How to Make Low Carb Philly Cheesesteak Casserole

When I made this casserole, I sautéed all the ingredients (except for the cheese) in my large electric skillet. You can also do this on the stove over medium high heat until the meat is cooked and the vegetables are tender.

Then, pour all the ingredients into a baking dish and top with provolone cheese.

Bake at 350 for 10-15 minutes, just to melt the cheese. 

I hope you love this Low Carb Philly Cheesesteak Casserole as much as we do! We ate ours with a salad for dinner. You could also pair it with some other low carb sides for your family’s dinner.

I like to eat this casserole on top of a bed of lettuce and make it into a salad. You could serve a salad on the side too for even more veggies! 

Can you make this casserole ahead and freeze it?

I haven’t personally tried to make this casserole ahead and freeze it, but it does reheat really well for left overs. I would think that it is probably best fresh with the bell peppers though.

  3. Such a great idea for a casserole Angela! Thanks so much for linking it up at the MaMade Blog Hop! Don’t forget to stop back again next week to link up again and see if you’ve been featured :). Have a great week!

  4. This. Looks. Amazing!!! thanks for linking this up at Nomday Monday – I’m definitely going to have to make this!!!

  5. What a fast meal to put together, looks great. Thanks for linking up at Sweet and Savoury Sunday, stop by and link up again this weekend!

  6. This sounds great (minus the mushrooms, I’m allergic!). I’m thinking I would try doubling the recipe, freezing half and then once defrosted, only have to bake it the night of. I’m always looking for things my girls can pop in the oven before I get home!

  7. This looks really tasty. I bet I could get my husband to eat more salads this way. What a wonderful way to remove the bread from a great sub! Thanks for linking up at #theultimateparty today!

  8. Love philly cheesesteak…been low carbing it for awhile now and while I think of some meals/foods that I can make (minus the breads), I never thought of this one…thanks for sharing!!

  9. Looks good BUT swiss cheese on your steak? That’s not Philly style! 😀 Try Provolone or American! (I’m a south Jersey gal who has eaten more that her fair share of cheesteaks.)

  10. Thank you for this post! I’m wondering where you found your Hormel Natural beef slices? I am shopping tomorrow and love to pick some up. Thanks 🙂

  11. I LOVE everything Philly. Seriously. So, I’m wondering what the total grams of carbs this is. Not wanting Net, but total. Thank you so much for sharing this!

  12. So simple yet so delicious!! Just made this and made myself a salad with it (w/ no dressing) and I am in love. Thanks for posting 🙂

  13. I just made this with a slight twist. I’m not a Swiss cheese fan, so I substituted provolone. However, right before adding the provolone, while still in skillet, I added 4oz of Philadelphia cream cheese to it. After mixing it in, I covered it with the cheese, reduced the heat slightly and covered the skillet to let the cheese melt (I try to keep from heating up the kitchen during the summer). This was awesome! One of the few dishes that every member of my family will eat!! Thanks for the recipe!
