Step‑by‑Step Instructions for Low Carb Philly Cheesesteak Casserole

Step 1: Preheat Oven
Begin by preheating your oven to 375°F (190°C). While the oven warms, take a moment to grease a 9x13 casserole dish with a bit of olive oil or cooking spray to ensure your Low Carb Philly Cheesesteak Casserole comes out easily once baked.

Step 2: Sauté Vegetables
In a large skillet heated over medium heat, add diced onion, chopped green, and red bell peppers. Sauté these vegetables for about 5 to 7 minutes until they soften and the onions turn translucent. This step builds a flavorful base for your casserole, so stir occasionally to prevent sticking.

Step 3: Cook Beef
Add the ground beef to the skillet with the sautéed vegetables, continuing to cook for about 8 to 10 minutes until the beef is nicely browned and no longer pink. Be sure to break up any large chunks with a wooden spoon. Once cooked, drain any excess grease to keep your casserole light.

Step 4: Combine Fillings
Reduce the heat to low, then introduce the cream cheese, garlic powder, salt, and black pepper into the skillet. Stir them together for 2 to 3 minutes, allowing the cream cheese to melt and fully combine with the beef and vegetable mixture, creating a creamy filling for your Low Carb Philly Cheesesteak Casserole.

Step 5: Layer Mixture
Spread the beef and vegetable mixture evenly into the greased casserole dish, creating a solid base layer. This step ensures every bite of your casserole is loaded with those hearty and savory flavors. Press it down gently to compact the mixture slightly.

Step 6: Add Eggs
In a separate bowl, whisk the large eggs until their yolks and whites are fully combined. Pour the egg mixture evenly over the beef and vegetable filling in the casserole dish. This will help bind everything together as it bakes, adding extra protein to your meal.

Step 7: Cheese Layering
Generously sprinkle the shredded provolone and mozzarella cheeses over the top of the casserole, creating a beautiful, gooey layer that will melt and bubble as it bakes. Make sure to cover the filling evenly for maximum cheesiness in each bite.

Step 8: Bake
Place the casserole into the preheated oven and bake for 25 minutes. You'll know it’s ready when the top is golden brown and the cheese is bubbling, creating a mouthwatering aroma that fills your kitchen.

Step 9: Rest & Serve
After removing the casserole from the oven, allow it to cool for about 5 minutes before slicing. This brief resting period helps the casserole set, ensuring perfect slices for a satisfying serving of your Low Carb Philly Cheesesteak Casserole, ready to delight your family and friends!

Make Ahead Options

You'll enjoy delicious, homemade comfort food with minimal effort after a long day!

High Protein Low Carb Philly Cheesesteak Casserole Recipe FAQs

What should I look for in ground beef for this recipe?
Absolutely! When selecting ground beef, I recommend using lean options like 85/15 or 90/10. This helps prevent excessive grease that can make the casserole soggy. Look for meat that is bright red with minimal browning, and avoid any packages with dark spots or excessive liquid.

How long can I store the leftovers in the fridge?
Very! You can store leftovers in airtight containers in the refrigerator for up to 4 days. Make sure to allow the casserole to cool completely before placing it in the fridge to maintain its freshness.

Can I freeze the High Protein Low Carb Philly Cheesesteak Casserole?
Absolutely! For freezing, wrap the cooled casserole securely in plastic wrap and then in aluminum foil to prevent freezer burn. It can be stored in the freezer for up to 2 months. To reheat, thaw in the fridge overnight, then bake at 350°F (175°C) for about 20-25 minutes until heated through.

What’s the best way to reheat leftover casserole?
For best results, allow your leftover casserole to thaw in the refrigerator overnight if frozen. Preheat your oven to 350°F (175°C) and bake for 20-25 minutes, checking to ensure it's heated through. Alternatively, you can use a microwave, reheating in 1-minute intervals until warm, but the oven will yield a better texture.

Can this casserole be made dairy-free?
Yes! To make a dairy-free version, simply swap out the cream cheese for a dairy-free alternative, such as cashew-based cream cheese or a vegan spread. Use dairy-free cheese options for the toppings, and consider adding nutritional yeast for an extra cheesy flavor!

Can my pets eat the leftovers from this casserole?
While the ingredients in the High Protein Low Carb Philly Cheesesteak Casserole are largely safe for pets, it’s best to avoid giving them any cheesy or heavily seasoned leftovers.
