- 1 bell pepper, sliced – any color works, but I love the look of a mix!
- 8 oz sliced mushrooms – cremini are my go-to.
- 1 packet of low carb cheese sauce mix – find one you like, but I have a favorite!
- 4 oz cream cheese
- 1 cup beef broth – adds so much flavor, trust me.
- 4 oz provolone cheese slices – the real Philly deal!
See? Nothing too crazy, right? Let’s get cooking!
Ingredient Breakdown: Key Components
So, here’s the deal with the ingredients. The ground beef? That’s your protein powerhouse, keeping you full and happy! Onions and bell peppers bring that classic Philly flavor and a little crunch. Mushrooms add a savory depth that’s just *chef’s kiss*. The cheese sauce? Well, that’s where the magic happens, making everything melty and delicious. And, of course, the provolone seals the deal with that perfect cheesy topping!
Substitutions and Variations for Ingredients
Listen, I get it – sometimes you gotta work with what you’ve got! If you’re not a fan of ground beef, ground turkey or chicken work just fine. Veggie-wise, feel free to toss in some spinach or zucchini if you’re feeling adventurous. Cheese? Swiss or mozzarella could be a fun twist, too. Just be sure to use a low-carb cheese sauce mix to keep everything keto-friendly. Go wild, and make this casserole your own!
Let’s Make This High Protein Low Carb Philly Cheesesteak Casserole Recipe – Step-by-Step Instructions
Alright, friends, let’s get this show on the road! First things first: preheat your oven to 375°F (190°C). Then, grab your favorite baking dish – I usually use a 9×13 inch, but anything similar will work. Now, let’s get cooking! Don’t worry, it’s super easy, and I’ll walk you through it every step of the way. You’ll be enjoying a delicious High Protein Dinner in no time!
Preparing the Ground Beef and Vegetables
First up, we’re browning that ground beef. Throw it into a skillet over medium-high heat. Break it up with a spoon as it cooks. Once it’s browned all over, drain off any excess grease – nobody wants a greasy casserole! Next, toss in your sliced onions, bell peppers, and mushrooms. Cook these until they’re softened, about 5-7 minutes. Stir it frequently so nothing sticks to the bottom. I love the smell of the veggies cooking – it always makes me hungry!
Creating the Creamy Cheese Sauce
Okay, time for the cheesy goodness! In the same skillet (or a separate saucepan, if you prefer), follow the package directions for your low-carb cheese sauce mix, but here’s the secret: use beef broth instead of water. Trust me, it adds so much flavor! Once the cheese sauce mix is ready, reduce the heat to low and stir in the cream cheese until it’s completely melted and smooth. Keep stirring, or it might clump up on you. You want it *perfectly* smooth and creamy before you move on!
Assembling and Baking Your High Protein Low Carb Philly Cheesesteak Casserole
Now, for the fun part! Add your cooked ground beef and veggies to that glorious cheese sauce. Stir it all together until everything is well combined and coated in that creamy, cheesy goodness. Pour the whole shebang into your prepared baking dish. Next, lay those provolone cheese slices right on top, covering the entire surface. Finally, bake it in your preheated oven for about 20-25 minutes, or until the cheese is melted, bubbly, and lightly golden brown. Careful, it splatters!

Why You’ll Love This Philly Cheese Steak Casserole Recipe

Tips for Success: Mastering Your High Protein Low Carb Philly Cheesesteak Casserole
Okay, so, to make sure your casserole is perfect every single time, here are a few little tricks I’ve learned over the years! First, be sure to brown your ground beef *really* well. That extra bit of browning adds so much flavor! Don’t be afraid to let it get a little crispy around the edges. Also, letting the casserole rest for a few minutes after it comes out of the oven lets all the flavors meld together. Trust me, it makes a difference! And don’t skimp on the cheese – go for it!
Frequently Asked Questions About This High Protein Dinner
Alright, let’s get to those burning questions! I know you’ve got them, so I’ve got the answers! These are the questions I get asked all the time, so hopefully, this helps you out, too!
Can I make this ahead? Absolutely! This Philly Cheese Steak Casserole Recipe is perfect for meal prepping. You can assemble the entire casserole, but don’t bake it yet. Cover it tightly and store it in the fridge for up to 24 hours. When you’re ready to eat, just pop it in the oven and bake as directed. You might need to add a few extra minutes to the baking time if it’s coming straight from the fridge. Easy peasy!
What side dishes go well with this? Oh, the possibilities! Since this is a High Protein Low Carb Recipe, I usually go for some fresh veggies. A simple green salad with a light vinaigrette is always a winner. Roasted broccoli or asparagus are also fantastic, and they’re super easy to make while the casserole is baking. If you’re not strictly low-carb, some garlic bread would be amazing, too. But trust me, it’s pretty satisfying all on its own!
Is this recipe freezer-friendly? Yes, indeed! This High Protein Low Carb Philly Cheesesteak Casserole Recipe freezes beautifully. You can freeze it before baking (assembled, but not baked) or after baking (cooled completely). Just wrap it tightly in a layer of plastic wrap, then a layer of foil. It’ll keep in the freezer for up to 3 months. To reheat, thaw it in the fridge overnight and bake as directed (or reheat from frozen, adding a bit more time). Easy peasy!
Can I use different types of cheese? Sure, feel free to experiment! Provolone is the classic, but I have used a mix of provolone and mozzarella, which is delicious. You could even try a little provolone and a little cheddar for a different flavor. Just make sure it melts nicely!

So, you’ve got this amazing High Protein Low Carb Philly Cheesesteak Casserole Recipe, and you’re wondering what to serve with it? Don’t worry, I’ve got you covered! Since we’re keeping things low-carb, a big, fresh salad is always a winner. I love a simple green salad with a light vinaigrette.
