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). While it heats, prepare your 9×13 baking dish by spraying it thoroughly with non-stick spray to ensure easy removal of the casserole later. This simple step sets the stage for achieving that perfect, bubbly cheese topping in your Low Carb Philly Cheesesteak Casserole.
Step 2: Sauté the Vegetables
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the diced onion and bell peppers, sautéing them for about 5-6 minutes until they are softened and start to become fragrant. Stir in the minced garlic, cooking for an additional 30 seconds until it’s aromatic. This blend will add a delicious depth to your casserole.
Step 3: Cook the Ground Beef
Now, add 2 pounds of ground beef to the skillet with the sautéed vegetables. Season the mixture with salt and pepper to taste, then cook it for about 7-8 minutes, breaking the meat into small pieces until browned and no longer pink. If needed, drain any excess fat to keep your Low Carb Philly Cheesesteak Casserole from being greasy.
Step 4: Combine with Cream Cheese
Reduce the heat to low and stir in 2 tablespoons of Worcestershire sauce. Next, add the softened 8 oz cream cheese, mixing it into the beef and vegetable mixture until it’s fully melted and creamy. This will give the casserole a rich texture that makes every bite delightful.
Step 5: Assemble the Casserole
Transfer the hearty beef and vegetable mixture to your greased baking dish, spreading it out evenly across the bottom. Layer the top with 8 oz of torn provolone cheese, followed by 1.5 cups of shredded mozzarella. The cheese will melt beautifully, creating that signature cheesy goodness typical of a Philly cheesesteak.
Step 6: Bake the Casserole
Place the baking dish in your preheated oven and bake for 22-25 minutes. Keep an eye on the cheese until it becomes melted, bubbly, and golden brown on top. This final step completes your Low Carb Philly Cheesesteak Casserole, making it irresistible and mouthwatering.
Step 7: Cool and Serve
After baking, remove the casserole from the oven and let it cool for about 5 minutes. This allows the cheese to set slightly, making it easier to serve. The creamy, cheesy layers inside are sure to evoke the comforting flavors of a classic cheesesteak, making your dinner a hit!

Low Carb Philly Cheesesteak Casserole Recipe FAQs
What kind of ground beef should I use for this casserole?
Absolutely! For the best flavor and texture in your Low Carb Philly Cheesesteak Casserole, I recommend using ground beef with an 80/20 fat ratio. This higher fat content helps keep the meat juicy and flavorful. If you prefer a leaner option, ground turkey or chicken can work, but be aware that it may result in a drier texture.
How should I store leftovers from this casserole?
Storing leftovers is a breeze! Simply place any remaining Low Carb Philly Cheesesteak Casserole in an airtight container and keep it in the refrigerator for up to 4 days. This will help retain its moistness and flavors for your next meal!
Can I freeze my casserole for later?
Yes, you can! To freeze your Low Carb Philly Cheesesteak Casserole, allow it to cool completely, then cut it into individual portions and wrap them tightly in plastic wrap. Place the wrapped portions into freezer-safe containers or zip-top bags. Properly stored, it can last for up to 3 months in the freezer. Thaw overnight in the refrigerator before reheating.
What if my casserole seems too greasy?
No worries! If your casserole turns out greasy, it might be due to excess fat from the ground beef. I recommend draining any extra fat after cooking the meat, before mixing in the cream cheese. This will help achieve a firmer texture and prevent greasiness.
Is this casserole suitable for anyone with dairy allergies?
It’s essential to be cautious with dietary restrictions. The Low Carb Philly Cheesesteak Casserole contains several dairy ingredients, such as cream cheese, provolone, and mozzarella. If you or your guests have dairy allergies, consider alternatives like vegan cream cheese and dairy-free cheese blends!
How can I reheat the casserole without losing moisture?
To reheat the Low Carb Philly Cheesesteak Casserole while maintaining its deliciously creamy texture, I suggest using an oven set to 325°F (163°C).

Alternatively, a microwave with a damp paper towel will also help keep it nice and moist!
