Step‑by‑Step Instructions for Low Carb Philly Cheesesteak Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C) to prepare for baking. While the oven warms up, grab a 9×13 baking dish and lightly spray it with non-stick cooking spray to prevent your Low Carb Philly Cheesesteak Casserole from sticking.
Step 2: Sauté the Vegetables
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the diced onions and bell peppers to the skillet, cooking for 5-6 minutes until they soften and become translucent. Stir in the minced garlic and cook for an additional 30 seconds until fragrant, then remove from heat.
Step 3: Cook the Ground Beef
Add 2 pounds of ground beef to the skillet with the sautéed vegetables. Use a spatula to break the meat into smaller pieces as you cook. Season with salt and pepper, cooking until the beef is browned and fully cooked, about 7-8 minutes. Drain any excess fat from the skillet to keep the casserole lighter.
Step 4: Mix in the Creamy Sauce
Stir in 2 tablespoons of Worcestershire sauce, blending it into the meat mixture. Reduce the heat to low and add 8 ounces of softened cream cheese, stirring until the mixture is smooth and creamy. This will create a rich base for your Low Carb Philly Cheesesteak Casserole.
Step 5: Layer the Ingredients
Evenly spread the beef and vegetable mixture into the prepared baking dish. Tear pieces of 8 ounces of provolone cheese and layer it over the beef, ensuring every bite has a cheesy surprise. Then, top it off with 1.5 cups of shredded mozzarella cheese for an extra gooey finish.
Step 6: Bake the Casserole
Place the baking dish in the preheated oven and bake for 22-25 minutes. You’ll know it’s ready when the cheese is melted and bubbly, creating a tantalizing golden layer on top. Once done, remove from the oven and let it rest for about 5 minutes before serving to allow the flavors to meld beautifully.

Make Ahead Options
These Low Carb Philly Cheesesteak Casserole is perfect for busy home cooks looking to save time during the week! You can prep the entire casserole up to 24 hours in advance by following these steps: Cook the beef and vegetable mixture, then let it cool before transferring it to your baking dish. Cover it tightly with plastic wrap and refrigerate. This method maintains the casserole’s flavor and quality, so it will be just as delicious when you’re ready to bake it! When you’re ready to serve, simply add your cheeses on top (you can even pre-arrange this step), and bake for 22-25 minutes at 350°F (175°C) until bubbly and golden. Enjoy the ease of this meal as a nourishing dinner option!
Expert Tips for Low Carb Philly Cheesesteak Casserole
- Choose Quality Beef: Use high-fat ground beef (80/20) for a flavorful and juicy casserole. Leaner options may dry out during cooking.

Low Carb Philly Cheesesteak Casserole Recipe FAQs
What type of ground beef should I use for this casserole?
I recommend using ground beef with an 80/20 fat ratio for the best flavor and juiciness. The higher fat content keeps the casserole moist and adds richness to the dish. Leaner ground beef can dry out during cooking, so don’t shy away from a bit of fat!
How long can I store leftovers of the Low Carb Philly Cheesesteak Casserole in the fridge?
You can store leftovers in an airtight container for up to 4 days in the refrigerator. This makes for easy meal prep, allowing you to enjoy the casserole throughout the week without losing its delicious flavor.
Can I freeze the casserole, and if so, how?
Absolutely! You can freeze your Low Carb Philly Cheesesteak Casserole for up to 3 months. To freeze, let it cool completely, then transfer it to a freezer-safe container. Make sure to label and date it, and when you’re ready to enjoy it, thaw it overnight in the refrigerator before reheating.
What should I do if my casserole is too dry after baking?
If you find your casserole is dry, it might be due to overcooking or using leaner beef. To remedy this, you can add a splash of beef broth or a bit more cream cheese while reheating to bring back moisture. Also, ensure to keep an eye on your baking time; it should be bubbly but not overcooked.
Are there any dietary considerations or allergen concerns for this recipe?
This casserole contains dairy (cream cheese and cheeses), which may not be suitable for those with lactose intolerance or dairy allergies. If you need a dairy-free option, consider using dairy-free cream cheese and nutritional yeast for a cheesy flavor without the dairy. Always double-check your ingredient labels to ensure they meet your dietary needs!
