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). This ensures the Low Carb Philly Cheesesteak Casserole will bake evenly and thoroughly. While the oven warms up, take out a 9×13 baking dish and coat it generously with non-stick spray, so the casserole doesn’t stick during baking.
Step 2: Sauté the Veggies
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Once the oil is shimmering, add the diced onion and bell peppers, sautéing them for about 5-6 minutes. Stir occasionally until they become soft and fragrant, revealing their natural sweetness and adding depth to your casserole.
Step 3: Add Garlic and Cook
Stir in 2 minced garlic cloves to the sautéed vegetables. Cook for an additional 30 seconds, stirring continuously to prevent the garlic from burning. The aroma should be delightful, enhancing the overall flavor profile of your Low Carb Philly Cheesesteak Casserole.
Step 4: Brown the Ground Beef
Add the ground beef to the skillet, breaking it apart with a spatula as it cooks. Season with salt and pepper, cooking for about 7-8 minutes until fully browned. Drain any excess fat if necessary to keep the casserole from becoming greasy, ensuring a perfect base for the casserole.
Step 5: Mix in Worcestershire and Cream Cheese
Once the ground beef is browned, pour in the Worcestershire sauce, stirring until well combined. Then add 8 ounces of softened cream cheese to the beef mixture. Reduce the heat to low and mix until the cream cheese melts completely, creating a rich and creamy filling that embodies the essence of a cheesesteak.
Step 6: Assemble in Baking Dish
Carefully pour the beef mixture into your prepared baking dish, spreading it evenly. Layer 8 ounces of sliced provolone cheese over the top, ensuring a good coverage. Finish with 1.5 cups of shredded mozzarella cheese, creating a gooey topping that will melt beautifully in the oven.
Step 7: Bake to Perfection
Place the baking dish in the preheated oven and bake for 22-25 minutes. Keep an eye on it—when the cheese is melted, bubbly, and lightly golden on top, it’s time to take it out. Allow the casserole to cool for about 5 minutes before serving, letting the flavors settle into each delicious layer.

Make Ahead Options
These Low Carb Philly Cheesesteak Casserole preparations are perfect for busy home cooks looking to save time during the week! You can prepare the beef and vegetable mixture up to 24 hours in advance; simply sauté the onions, bell peppers, and ground beef, then mix in the cream cheese and Worcestershire sauce. Once fully combined, let it cool before transferring to an airtight container in the refrigerator. When it’s time to serve, layer the cheese on top and bake as directed. This method ensures every bite is just as delicious as if it were freshly made, allowing you to enjoy a comforting meal on hectic evenings with minimal stress.

Low Carb Philly Cheesesteak Casserole Recipe FAQs
What is the best way to choose my produce, like bell peppers and onions?
Absolutely! When selecting bell peppers, look for ones that are firm, vibrant in color, and free of dark spots or wrinkles. For onions, choose those that are heavy for their size, have dry skins, and avoid any soft spots. The fresher the produce, the better the flavor in your Low Carb Philly Cheesesteak Casserole!
How should I store leftovers from my casserole?
I recommend storing leftovers in an airtight container in the refrigerator for up to 4 days. This keeps the flavors fresh! You can simply reheat in the oven at 325°F (165°C) for a delicious second helping.
Can I freeze my Low Carb Philly Cheesesteak Casserole? If so, how?
Absolutely! For freezing, allow the casserole to cool completely, then portion it into airtight containers or heavy-duty freezer bags. It can be frozen for up to 3 months. When you’re ready to enjoy it again, thaw it overnight in the fridge and reheat in the oven for best results!
What if I don’t have cream cheese? Can I substitute it?
Very! If you’re out of cream cheese, you can substitute it with ricotta cheese for a slightly different flavor or use a combination of sour cream and Greek yogurt. Just ensure it’s softened before mixing it in to get that creamy texture you want.
Can I add ingredients to meet dietary requirements?
Of course! You can easily customize this casserole to suit dietary needs. For instance, if you’re avoiding dairy, try using dairy-free cheese alternatives. For those with gluten sensitivities, ensure all your sauces and seasonings are labeled gluten-free. Just keep in mind, it may alter the final taste and texture slightly.
What should I do if my casserole comes out too greasy?
If your casserole seems greasy, it may be due to the fat in the ground beef. I often use leaner ground beef (90/10) to reduce grease, and don’t forget to drain the excess fat after cooking the meat!
