How to Make Low Carb Philly Cheesesteak Casserole
Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This ensures that your casserole bakes evenly and gets nice and bubbly when it’s time to cook.
Step 2: Sauté the Vegetables
Heat the olive oil in a large skillet over medium heat. Add the diced onions and bell peppers, cooking them for about 5-6 minutes until they start to soften. Then add the minced garlic and cook for an additional 30 seconds. This step is key because sautéing brings out the natural sweetness of the vegetables, creating a lovely base for your casserole.
Step 3: Brown the Beef
Next, add the ground beef into the skillet with the softened vegetables. Season with salt and pepper to taste. Cook while breaking up the meat with a spatula until it’s completely browned—this should take about 7-8 minutes. Browning the beef adds depth of flavor that really makes this dish shine!
Step 4: Flavor It Up
Stir in the Worcestershire sauce, letting it coat everything nicely. This adds richness and enhances all those delicious flavors we’ve created so far.
Step 5: Make It Creamy
Reduce heat to low and add in the softened cream cheese. Stir until it melts completely and coats everything evenly. This will create that creamy texture we love in casseroles!
Step 6: Assemble Your Casserole
Once everything is combined, transfer this flavorful mixture into your prepared baking dish, spreading it out evenly.
Step 7: Cheese Layering Time!
Now comes one of my favorite parts—layering! Place slices of provolone cheese over your beef mixture first. Follow that by sprinkling shredded mozzarella on top. All that gooey cheese is going to melt beautifully as it bakes!
Step 8: Bake Until Golden
Place your casserole into the preheated oven and bake for about 20-25 minutes. Keep an eye on it until you see that cheese bubbling up beautifully and turning slightly golden on top.
Step 9: Let It Rest
After baking, allow your casserole to rest for about 5 minutes before serving. This step helps all those amazing flavors meld together perfectly and makes everything easier to serve.
And there you have it! A warm and inviting Low Carb Philly Cheesesteak Casserole that’s bound to become a favorite at your dinner table. Enjoy every cheesy bite!
Pro Tips for Making Low Carb Philly Cheesesteak Casserole
This casserole is already a winner, but these pro tips will help you take it to the next level!

-
Customize your veggies: Feel free to swap in other vegetables like mushrooms or zucchini. They add extra nutrients and can give the dish a unique twist while keeping it low carb.
-
Experiment with cheese: While provolone and mozzarella are classic choices, mixing in some cheddar or pepper jack can introduce new flavors that keep every bite exciting!
-
Make it ahead of time: Preparing this casserole the night before allows the flavors to meld beautifully. Just cover it and pop it in the fridge until you’re ready to bake!
-
Don’t skip the resting time: Allowing the casserole to sit for 5 minutes after baking helps it set, making serving easier and ensuring each slice holds together beautifully.
