Philly Cheese Steak Casserole

Philly cheese steak casserole is a low carb casserole recipe that’s full of good stuff! Beef, peppers, onions, and plenty of cheese make this casserole hearty and filling.


We lived in Nebraska a few years ago and they opened a cheese steak joint just before we moved away.

Those were the best 2 weeks of my life, basically.

We’re back in Illinois now and I’m here to tell you that Philly cheese steaks are just not a huge thing here. I mean, most restaurants have them, but none of them really do them very well.

An authentic Philly cheese steak is worth it’s wait in gold, if you ask me. 😉

This Philly cheese steak casserole recipe certainly isn’t authentic since I’ve skipped the bun and started with ground beef in place of steak, but oh man. So amazing!

Philly cheesesteak casserole recipe:

I started with ground beef (blasphemous, I know) because it’s simple, cheap, and I always have it in my fridge. You can totally use thinly sliced beef in place of ground if you prefer, but this is actually really good just the way it is! Give it a try and see!

Brown the meat along with some diced onions, peppers, and a little garlic.

You can add in mushrooms, if you like. I’m not a fan, personally.

I season my Philly cheese steaks with Lawry’s seasoned salt. It adds great flavor to the dish!

Assembling this casserole is easy. Add your beef mixture to a 9×9 baking dish and top it off with provolone cheese. You can use grated or you can just tear slices of cheese into smaller pieces. Don’t layer the cheese on in whole pieces, because we’re about to dump some eggs over the top.

Yep. I said we’re adding eggs to this casserole. They work to bind the casserole together, but I promise that this recipe doesn’t taste eggy at all.

You’ll whisk together 4 eggs, a little cream, and a dash of hot sauce.

Pour that mixture over the top of your casserole. The eggs will work themselves down into all of the cracks between the meat and cheese.

Pop this casserole into the oven and bake until the eggs are set.

I let this cool for about 5 minutes before slicing into 6 pieces and serving.

  1. I loved this!!! I put some primal steak sauce on it and it was awesome! Will be making it again and again for sure. Thank you so much!

    1. Donna, have you tried assembling it in advance and cooking it the next day? I want to make this for a teen retreat, but due to time constraints, need to be able to do the prep the day before we bake and serve it.

  2. Made this tonight. We loved it. I didn’t have provolone, so I mixed it up with what I had- a combo of Havarti, Gouda, and Swiss. So customizable. It was awesome. My husband add a little extra Tapatio to his- he said it was delicious. Thank you for this recipe. We’ll be making it again.

    Great, easy, yummy recipe…my family enjoyed it. “This is sooo good”, repeated my six year old at the dinner table. It honestly did taste like a good old fashioned philly cheese steak. I did go heavier on the garlic and Worcester and also added a fair amount of teriyaki sauce. I rounded up to 2# of meat because of previous comments saying the dish was eggy and I didn’t think it was eggy at all. I also added a can of mushrooms to the whole casserole and diced banana peppers to the adult side of the casserole. Since I used more meat and veggies I used six slices of provolone instead of 5. I also used milk and butter instead of cream. We will most certainly be making this again!

  4. How many grams is 4 slices of provolone cheese exactly? This are a bit different here in Aus! Thanks 🙂

      I really don’t know. Just use your best judgement for how cheesy you want it. I used sandwich slices, if that helps.

  5. Judy Kovello

    Just love your recipes and like to try different things. Just your regular home cooked things. I can’t eat any types of peppers so I really haft to change it up, and with most of your recipes I can leave out the things I don’t like and just add in other ingredients.

    1. Karly Campbell

      So glad you enjoy the recipes, Judy! You could definitely leave out the peppers here and try adding in some mushrooms. I don’t cook with mushrooms often, so I can’t say it will work for sure, but I bet it does. 🙂

    1. Joan Powers

      Did you dilute the soup at all? My husband doesn’t like eggs so I was hoping there was an alternative.

  6. This is one of our favorites, thanks for sharing it on facebook & reminding me I need to make it again! I do have a bone to pick….I can’t believe you are not a mushroom fan, I thought sure we were soul mates since every recipe you post is something I love! Oh well, guess I will make an allowance & just keep making your recipes & adding mushrooms 🙂

  7. LEANNA M WYLIE

    I have made this several times and it’s a favorite!! I thought I was reading the other day where you had also tried using thin cut steak but I can’t seem to find that comment now.

    1. Karly Campbell

      You could definitely use thinly sliced steak – just lightly cook it before adding to the casserole. 🙂

  8. Turned out amazing I added my own seasoning and added Parmesan cheese also and used 2%milk Will definitely make again❤️❤️❤️❤️❤️❤️

  9. Another winner! I’m adding this to my make again recipe file. I am so not a cook, but I actually changed this some. I didn’t have seasoned salt, so I threw in smoked paprika, onion powder, and turmeric. I cut out one egg, just because I’m not a quiche person. And I didn’t have provolone so I used mozzarella. This turned out amazing, even though I had to substitute a little. I highly recommend this recipe.

  10. I’m 100% Keto, OMAD and loving life, This was my treat for me and the family after my 48 hour fast, I made it with 1 KG of the local butchers 70/30 beef mince (Grass fed, (as we live in New Zealand) 6 x free range eggs and 1/2 cup of cream (due to extra mince). Everything else much the same, apart from some fresh herbs when cooking the mince, and the cheese…. oh that wonderful star ingredient!!
    The only thing I changed, was I left the amazing infused oil from the skillet in with the meat and all… Best mince dish I have had for a very long time, and no… there were no leftovers.
    American classic, now a New Zealand favourite.

        With fresh green peppers and 2 banana peppers,picked an hour before this is the best. My husband abso,utely licked his plate clean

          Right now ribeyes are cheaper than hamburger so i used two ribeyes very thinly sliced….best ever

          1. Sandra Schultz

            I would like to know what part of the country you live in due to you being able to buy ribeyes cheaper than hamburger, as I’ve never seen that happen. This caught my eye and sounds delicious. We raise Angus beef cattle, prices are down right now on cattle, but again never seen ribeye cheaper than hamburger. Thank you, Nancy, for your reply.
