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.
