Preparing the Steak and Vegetables
First things first, let’s get that oven preheated to 350°F so it’s nice and ready. Now, grab your shaved steak. I like to give it a good sprinkle of salt and pepper right from the start. Heat up that avocado oil in a big skillet over medium-high heat – you want it nice and hot! Toss in the steak and cook it quickly, just about 2 minutes per side until it’s beautifully browned. Don’t overcook it! Scoop it out, let it cool just a smidge, then give it a quick chop. Now, into that same skillet, throw in your chopped onion and bell pepper strips. Sauté them for about 6 minutes, or until they start to soften up and smell amazing. Stir in the garlic powder, season again with salt and pepper if you fancy, and then bring that chopped steak back into the pan. Give it all a good stir to combine. We’re almost there!
Crafting the Creamy Cheese Sauce
While your veggies and steak are hanging out, let’s get that luscious cheese sauce going. Grab a saucepan and melt that tablespoon of butter over medium heat. Pour in your beef broth and let it come to a gentle simmer. Now, pop in those cubes of cream cheese! Keep whisking gently until it’s all melted and smooth. This is where the magic happens! Turn the heat down to low, so it doesn’t scorch, and add in 8 ounces of your grated provolone cheese. Stir it around until it’s completely melted and gooey. You want a nice, silky sauce that coats the back of a spoon. It smells incredible already, right?
Assembling and Baking Your Low Carb Philly Cheesesteak Casserole
Now for the grand finale! Pour that dreamy cheese sauce right into the skillet with your steak and veggie mixture. Stir it all together until everything is coated in cheesy goodness. Next, transfer this deliciousness into your casserole dish. Make sure to spread it out evenly. Now, take that remaining provolone cheese and sprinkle it all over the top. Go ahead, be generous! Pop that dish into your preheated oven and let it bake for about 25 to 30 minutes. You’re looking for it to be nice and bubbly around the edges and that cheese on top to be perfectly melted and maybe even a little golden brown. It’s the moment of truth for your Low Carb Philly Cheesesteak Casserole!
Tips for the Best Low Carb Philly Cheesesteak Casserole

First off, when it comes to the steak, don’t be afraid to really get a good sear on it. That little bit of browning adds so much flavor! And for the veggies, cook them until they’re tender but still have a slight bite – nobody likes mushy onions, right? When you’re making that cheese sauce, don’t rush it. Let that cream cheese and provolone melt together *slowly* over low heat to get that super smooth, dreamy consistency. And if you’re a real cheese fanatic, you could even try a little sprinkle of mozzarella in there with the provolone for extra gooeyness!

Ingredient Notes and Substitutions
Let’s chat ingredients for a sec! I know sometimes you might not have *exactly* what a recipe calls for, and that’s totally okay. For this casserole, the shaved steak is pretty crucial for that classic Philly feel, but if you absolutely can’t find it, you could thinly slice some ribeye or even use ground beef in a pinch, though it’ll change the texture a bit. Avocado oil is my go-to because it’s healthy and handles heat like a champ, but olive oil or even just a neutral vegetable oil will work. Provolone is the traditional cheese, giving it that signature tang, but a mix of mozzarella and a sharp white cheddar would be delicious too if you want to get creative!
Make-Ahead and Storage for Your Low Carb Philly Cheesesteak Casserole
One of the best things about this Low Carb Philly Cheesesteak Casserole is how fantastic it is for getting ahead! Believe me, knowing you have a delicious, healthy meal waiting is the *best* feeling. If you’re a meal prep pro, you can totally assemble the whole thing (minus the final cheese topping if you want it super fresh) and pop it in the fridge for up to 2 days. Just add the cheese and then bake when you’re ready! Leftovers are a dream, too. Store them in an airtight container in the fridge for about 3 days. Reheat gently in the microwave or pop it back in the oven at that same 350°F for a few minutes until it’s warmed through and bubbly again.

Frequently Asked Questions about Low Carb Philly Cheesesteak Casserole
Got questions about whipping up this cheesy delight? I’ve got you covered! It’s pretty straightforward, but here are a few things folks often ask:
Can I use a different type of meat in this casserole?
Absolutely! While shaved steak gives you that classic Philly vibe, you can totally switch it up. Ground beef or ground turkey works really well and browns up easily. Just make sure to drain off any excess fat after cooking. Some people even love using thinly sliced chicken breast for a different twist!
Is this recipe freezer-friendly?
Yes, it is! This Low Carb Philly Cheesesteak Casserole freezes like a charm. After it’s completely cooled, portion it into freezer-safe containers or wrap individual servings tightly. It should stay good in the freezer for about 2-3 months. Just thaw it in the fridge overnight and reheat as usual.
What are some good side dishes to serve with it?
Since this casserole is pretty hearty and packed with flavor, it pairs wonderfully with lighter sides. A simple green salad with a vinaigrette is a fantastic choice to balance things out. Steamed broccoli or green beans are also great low-carb options that complement the rich flavors.
