    Preparing the Steak and Veggies

    First things first, get that oven preheating to 350°F (175°C). While it’s warming up, give your steak a good sprinkle of salt and pepper. Now, grab your big skillet and heat up that avocado oil over medium-high heat. Carefully add the steak – trust me, don’t crowd the pan, or it’ll steam instead of brown! Cook it for just a couple of minutes per side until it’s nicely browned. Then, scoop it out, let it cool just a smidge, and give it a rough chop. Toss the chopped onion and bell pepper strips into the same skillet. Sauté them for about 6 minutes until they’re nice and soft. Stir in your garlic powder, season with a little more salt and pepper if you think it needs it, and finally, add the chopped steak back in. Give it all a good mix and take the pan off the heat. Easy peasy!

    Crafting the Creamy Cheese Sauce

    Now for that luscious cheese sauce, the heart of any good casserole! In a separate saucepan, melt that tablespoon of butter over medium-high heat. Pour in the beef broth and let it come to a simmer. Lower the heat to medium and toss in your cubed cream cheese. Whisk it like you mean it until it’s all smooth and melty – no lumps allowed! Once that’s perfect, turn the heat down to low and stir in 8 ounces of your grated provolone cheese. Keep whisking until it’s lusciously melted and creamy. Oh, the smell!

    Assembling and Baking the Casserole

    Here comes the fun part: bringing it all together! Pour that glorious cheese sauce right into the skillet with your steak and veggie mixture. Stir it all up so that every bite is coated in cheesy deliciousness. Now, carefully transfer all of that into your casserole dish. Spread it out evenly. Top it off with the remaining 8 ounces of provolone cheese – make sure you get good coverage! Pop that into your preheated oven and let it bake for about 25 to 30 minutes. You’re looking for that bubbly, golden-brown perfection on top. Seriously, it looks and smells amazing when it’s done!

    Frequently Asked Questions about Low Carb Philly Cheesesteak Casserole

    Got questions about this cheesy dream? I’ve got answers! Let’s make sure your Low Carb Philly Cheesesteak Casserole turns out absolutely perfect.

    Can I use different vegetables in this casserole?

    Absolutely! While onions and bell peppers are classic, feel free to get creative. Mushrooms are a fantastic addition – just sauté them with the onions and peppers until they release their liquid. You could also try adding a bit of chopped jalapeño for a little heat, or even some finely diced celery for extra crunch and flavor. Just make sure not to go overboard with starchy veggies if you’re sticking strictly to keto!

    What kind of steak is best for this recipe?

    For this casserole, shaved steak is ideal because it cooks super fast and distributes beautifully throughout the dish. You can often find it pre-shaved in the grocery store meat section, which saves a ton of time! If you can’t find shaved steak, you can thinly slice a sirloin or ribeye steak yourself. Just make sure you slice it super thin against the grain for tenderness. Avoid tougher cuts like flank steak unless you plan on marinating and tenderizing it first.

    Is this recipe truly low carb and keto-friendly?

    Yes, this Low Carb Philly Cheesesteak Casserole is fantastic for anyone following a low-carb or ketogenic lifestyle! The main carb sources in a traditional cheesesteak are the hoagie roll and sometimes added sugar in condiments. By skipping the bread and using whole ingredients, we’ve kept the carb count super low. The primary carbs come from the onions and peppers, which are naturally low in carbs when used in moderate amounts. It’s a winner for satisfying those cravings without derailing your diet!

    Can I use different types of cheese?

    Provolone is traditional for a reason – it melts wonderfully and has that perfect nutty, sharp flavor that complements the steak. But honestly, feel free to experiment! Mozzarella adds an amazing gooey stretch, and a little bit of sharp cheddar can bring a nice tang. You could even mix in some Swiss for a different flavor profile. Just make sure you’re using real cheese and not pre-shredded mixes that can sometimes have anti-caking agents that affect the melt. About half the cheese goes into the sauce and the other half on top for that lovely crust!
