Gather Your Ingredients for the Low Carb Philly Cheesesteak Casserole
Okay, let’s get our game faces on and gather everything we need for this amazing Low Carb Philly Cheesesteak Casserole. It’s really straightforward, but having everything prepped makes the whole cooking process smoother. Trust me on this one!
For the main event, you’ll want about 2 pounds of shaved steak. It cooks up so fast, which is perfect. We’ll also need 1 tablespoon of avocado oil for sautéing, because it can handle the heat. Then comes the veggies: a nice big 1 chopped onion and 1 bell pepper, which you can chop into about ½ inch strips. Any color pepper works, but red or green add a lovely splash of color! Don’t forget 1 teaspoon of garlic powder for that savory kick, and of course, salt and pepper to make everything sing.
Now for the cheesy goodness! You’ll need 16 ounces of provolone cheese. This is key, so make sure you have it all ready to go. We’re going to divide it, so think of that as half for the middle and half for the glorious topping. And for our creamy, dreamy sauce, we’ll grab 1 tablespoon of butter, about ¾ cup of beef broth (make sure it’s good quality!), and 4 ounces of cream cheese, cubed up for easy melting.

Step 1: Prepare the Steak and Vegetables
First things first, let’s get that oven preheated to 350° F. While it’s warming up, give your steak a good sprinkle of salt and pepper – just how you like it. Now, grab a big skillet and heat up that avocado oil over medium-high heat. Toss in the steak and let it brown up nicely, usually about 2 minutes on each side is perfect. Don’t overcook it! Once it’s browned, take it out and let it cool just a smidge before giving it a rough chop. Clean out the skillet if needed, then add your chopped onion and bell pepper strips. Let them soften up for about 6 minutes. Stir in the garlic powder, give it another quick season with salt and pepper, then toss the chopped steak back in. Mix it all together and take it off the heat for now.
Step 2: Create the Creamy Cheese Sauce
Time for that luscious sauce! Melt the butter in a saucepan over medium-high heat. Pour in the beef broth and bring it just to a simmer. Now, lower the heat to medium and add your cubed cream cheese. Whisk it like crazy until it’s all melted and smooth – this is where the magic happens! Once that’s silky, reduce the heat to low and stir in 8 ounces of your provolone cheese. Keep stirring until it’s completely melted and gorgeous. You want it smooth and creamy, so don’t be afraid to whisk!
Step 3: Combine and Bake the Casserole
Now for the grand finale! Pour that beautiful cheese sauce right over the steak and veggie mixture in the skillet. Give it a good stir so everything is coated in cheesy goodness. Carefully transfer this whole mixture into your favorite casserole dish. 
Sprinkle the remaining 8 ounces of provolone cheese all over the top – make it generous! Pop it into your preheated oven for about 25 to 30 minutes. You’re looking for it to be bubbly and heated all the way through. It’ll smell amazing!
Tips for the Perfect Low Carb Philly Cheesesteak Casserole
You know, making this Low Carb Philly Cheesesteak Casserole is pretty foolproof, but I’ve picked up a few little tricks that make it extra special. First off, for the steak, make sure it’s really thinly shaved. If yours is a bit thicker, just give it a quick chop after cooking so it’s easier to eat in every bite. Also, when you’re making that glorious cheese sauce, don’t rush the melting process! Keep the heat on low and whisk gently so you get a super smooth, creamy sauce without any chance of it breaking. And when it comes to baking, that bubbly, golden-brown cheese top is your sign that it’s ready to go. Want more meal prep ideas? This casserole is a lifesaver!
Ingredient Notes and Substitutions
You know, the beauty of this Low Carb Philly Cheesesteak Casserole is how adaptable it is! If you can’t find shaved steak, don’t sweat it. You can totally use thinly sliced ribeye or sirloin; just make sure to slice it really thin against the grain before cooking. For the cheese, while provolone is classic, a mix of provolone and mozzarella works wonderfully too! And if you’re not a fan of avocado oil, a good quality olive oil or even some plain ol’ vegetable oil will do the trick in a pinch. It’s all about making it work for you and your pantry!
Make-Ahead and Storage for Your Low Carb Philly Cheesesteak Casserole
This Low Carb Philly Cheesesteak Casserole is an absolute champ when it comes to making life easier, especially during busy weeks! You can totally assemble the whole thing, minus the final topping of cheese, and pop it in the fridge. Just cover it tightly with plastic wrap and foil. When you’re ready to bake, pull off the plastic wrap, add that last layer of provolone, and bake it – you might just need to add a few extra minutes to get it all bubbly. Leftovers? Oh yeah, they’re great! Store them in an airtight container in the fridge for up to 3-4 days. Reheat gently in the microwave or pop a portion back in the oven until warmed through. It’s almost as good the second time around!

Master of Culinary Visual Arts
My culinary journey started in the fast-paced kitchens of boutique coastal restaurants throughout Southern California, where I learned that beautiful food doesn’t have to be complicated. After nine years of professional cooking, I’ve made it my mission to prove that sophisticated, nutritionally sound meals can be accessible to busy home cooks who refuse to compromise on flavor or visual appeal.
What changed everything for me was watching talented home cooks feel intimidated by healthy cooking. That’s when I transitioned to private instruction, teaching busy professionals and families how to create restaurant-quality meals using simple techniques and ingredients they can actually find at their local grocery store. My “15-minute meal” frameworks are now used by several regional cooking schools!
As a third-generation Mexican-American, I love weaving vibrant Latin flavors into low-carb creations – proving that healthy eating can be both culturally authentic and visually spectacular. My “effortless elegance” philosophy is simple: nutritious food should look as stunning as it tastes, without requiring professional chef skills or expensive equipment.
When I’m not developing recipes in my San Diego coastal kitchen, you’ll find me surfing the local breaks with my Golden Retriever mix, Mango, who’s both my kitchen companion and unofficial taste-testing assistant. My personal low-carb lifestyle started as a way to maintain energy for my active coastal life, and it’s become the foundation for proving that healthy eating enhances rather than restricts life’s pleasures.
