How to Make the Best Low Carb Philly Cheesesteak Casserole
Alright, let’s get this party started! Making this casserole is super simple, honestly. You just need to follow a few easy steps, and soon you’ll be digging into a dish that tastes like a decadent treat but keeps you happily low-carb. Trust me, it’s so satisfying! You can even plan some super tasty veggie sides to go with it using tips from how to make veggie sides.
Prepping the Ingredients
First things first, get that oven preheated to 350°F (175°C). While it’s warming up, let’s get our steak ready. Just give it a good seasoning with salt and pepper. If your shaved steak isn’t already in manageable pieces, give it a quick chop so it’s easier to work with later.
Cooking the Steak and Vegetables
Now, grab a big skillet and pop in that avocado oil over medium-high heat. Once it’s nice and hot, add your seasoned steak. You only need to cook it for about 2 minutes per side until it’s nicely browned. We’re not cooking it through just yet! Take the steak out of the skillet, let it cool just a tiny bit, and then give it a rough chop. Toss your chopped onion and bell pepper strips into that same skillet (don’t you dare clean it!). Cook ’em until they’re nice and soft, about 6 minutes. Stir in that garlic powder, season with a pinch more salt and pepper if you think it needs it, then put the chopped steak back in. Give it a good mix, and then take the skillet off the heat.
Creating the Creamy Cheese Sauce
Time for the magic ingredient: the cheese sauce! In a saucepan, melt that tablespoon of butter over medium-high heat. Pour in the beef broth and let it come to a gentle simmer. Now, turn the heat down to medium and add your cubed cream cheese. Whisk it around often until it’s super smooth and melted. Keep that heat low, and stir in about half of your grated provolone cheese until it’s all melty and gooey. Mmm, smells good already, doesn’t it?

Assembling and Baking Your Low Carb Philly Cheesesteak Casserole
Okay, this is where it all comes together! Pour that dreamy cheese sauce right into the skillet with your steak and veggies. Give it a really good stir so everything is coated beautifully. Next, carefully transfer this whole glorious mixture into your casserole dish. Sprinkle the rest of that provolone cheese evenly over the top. Now, pop it into your preheated oven and bake for about 25 to 30 minutes. You’ll know it’s ready when it’s all bubbly around the edges and looks wonderfully heated through.
Tips for the Perfect Low Carb Philly Cheesesteak Casserole
Want to make sure your Low Carb Philly Cheesesteak Casserole is absolutely spot-on every time? I’ve got a few little secrets that have worked wonders for me. First off, don’t skimp on the steak quality! Shaved ribeye is typically used for Philly cheesesteaks, and it really makes a difference here, giving you that rich flavor. Also, make sure your vegetables aren’t too wet when they go into the pan; nobody wants a watery casserole! And when it comes to cheese, just use the good stuff – provolone is classic for a reason!

Ingredient Notes and Substitutions for Your Casserole
Let’s chat about some of these ingredients! For the steak, shaved ribeye is *chef’s kiss*, but honestly, any thinly sliced steak works great. If you can’t find shaved steak, just buy a good cut and slice it super thin yourself while it’s still a little frozen – makes it so much easier! Instead of avocado oil, olive oil or even some reserved bacon fat would be yummy. Any color bell pepper is totally fine, and if you’re not a fan of onions, you could skip those or use a little onion powder instead. For the cheese, provolone is traditional and melts like a dream, but a sharp white cheddar or even mozzarella would be delicious too!

Certified Therapeutic Nutrition Specialist
My journey into medical low-carb nutrition began when my four-year-old daughter was diagnosed with epilepsy. When neurologists recommended the Modified Atkins Diet as seizure management, I found myself in uncharted territory where recipe failures could literally trigger neurological episodes.
As a registered nurse with pediatric experience, I had the clinical knowledge but needed to learn how to translate medical protocols into family-friendly meals. I spent three years documenting every successful adaptation and breakthrough that made medical nutrition feel less like punishment and more like nourishment for our family’s unique needs.
I’ve developed over 190 medically-compliant recipes, each tagged with precise macro calculations and detailed notes about which health conditions benefit most. My collaboration with pediatric neurologists at Children’s Hospital of Philadelphia resulted in the first comprehensive cookbook for families managing childhood epilepsy through diet – work that’s now used by three major children’s hospitals.
When I’m not reading medical journals or practicing violin for stress relief, I’m advocating for insurance coverage of medical foods and helping school districts accommodate students on prescribed ketogenic protocols. Medical nutrition isn’t about perfection – it’s about precision applied with compassion.
