HOW TO MAKE CHEESY LOW CARB PHILLY CHEESESTEAK CASSEROLE
Let’s walk through each step of this hearty, cheesy casserole journey. From sizzling the seasoned beef to pulling a golden, bubbling masterpiece out of the oven, these instructions will guide you to Philly-inspired perfection.
1. Preheat the Oven
Begin by setting your oven to 375°F (190°C). This ensures a consistent baking temperature so that your cheese topping melts evenly and achieves that gorgeous golden-brown finish.
2. Brown the Beef
In a large skillet over medium-high heat, pour in the olive oil. Once shimmering, add the ground beef, breaking it apart with a spatula. Cook until the beef is fully browned, stirring occasionally. If there’s excess grease pooling, carefully drain it off to keep the casserole from becoming too oily.
3. Sauté the Veggies
Toss the thinly sliced onion, green bell peppers, and red bell pepper into the skillet with the beef. Continue to sauté for several minutes, stirring frequently, until the vegetables become tender but still hold a bit of bite.
4. Season the Mixture
Sprinkle in the garlic powder, onion powder, paprika, salt, and black pepper. Stir well so the seasonings coat every piece of beef and veggie, building layers of bold flavor.
5. Add the Cream Cheese
Reduce the heat to low and dollop the softened cream cheese into the skillet. Stir continuously until the cream cheese is fully melted and the mixture turns luxuriously smooth and creamy.
6. Incorporate Worcestershire and Provolone
Pour in the Worcestershire sauce, then stir in half of the shredded provolone. Keep stirring until the cheese melts into the filling, creating an extra-rich consistency.
7. Transfer to Casserole Dish
Grease a 9×13-inch casserole dish, then spoon the beef and vegetable mixture into it. Use a spatula to spread it into an even layer, distributing the cheesy filling across the dish.
8. Add the Cheese Topping
Sprinkle the remaining provolone and all of the mozzarella cheese evenly over the casserole’s surface, ensuring every bite will have that irresistible cheese pull.
9. Bake Until Bubbling
Place the dish in the preheated oven and bake for 20–25 minutes, or until the cheese is bubbling and starting to turn a light golden brown.
10. Garnish and Serve
Remove the casserole from the oven and let it rest for a few minutes to set. Sprinkle chopped fresh parsley over the top for a vibrant, herbaceous finish before slicing and serving.
SERVING SUGGESTIONS FOR CHEESY LOW CARB PHILLY CHEESESTEAK CASSEROLE
After all that bubbling, cheesy goodness comes out of the oven, it’s time to plate up and personalize your perfect dinner experience. Whether you’re serving a cozy family meal or impressing guests at a casual gathering, these suggestions will elevate every serving into something extraordinary. With a balance of textures and temperatures, you’ll highlight the casserole’s rich flavors while adding complementary contrasts. Let’s explore four creative ways to present and pair this low carb delight.
- Serve alongside Cauliflower Rice Pilaf for an extra-low-carb twist. Fluff lightly steamed cauliflower rice with a bit of butter, minced herbs, and a sprinkle of grated Parmesan, then pile a generous scoop next to a hearty casserole slice.
- Offer a crisp Garden Salad dressed in a tangy vinaigrette. The fresh greens—romaine, arugula, cherry tomatoes, and shaved cucumber—offset the casserole’s creaminess, adding a refreshing pop of color and crunch.
- Top each portion with Pickled Jalapeños or a drizzle of your favorite hot sauce. The tangy heat cuts through the richness and adds a bold contrast, perfect for spice lovers craving an extra kick.

HOW TO STORE CHEESY LOW CARB PHILLY CHEESESTEAK CASSEROLE
Storing leftovers properly ensures your Cheesy Low Carb Philly Cheesesteak Casserole stays just as delicious on day two (or day ten!) as it was fresh from the oven. With the right techniques, you’ll preserve that creamy texture, vibrant flavors, and melty cheese without drying out or developing off-flavors. Below are a few trusted methods to keep this casserole tasting its best for quick meals, easy lunches, or spontaneous dinner plans.
- Refrigerate in an Airtight Container
Let the casserole cool completely to room temperature, then transfer individual slices or the entire dish into a sealed container. Stored this way, it will stay fresh in the refrigerator for up to 2 days.
- Freeze in Portion-Sized Containers
If you want to enjoy this cheesy comfort food later, cool the baked casserole fully, then divide it into single-serving, freezer-safe containers. Seal tightly and freeze for up to 1 month. Thaw overnight in the fridge before reheating.
- Cover the Baking Dish
If you plan to bake it within the next day, simply cover the casserole dish with plastic wrap or a tight-fitting lid and keep it in the fridge. When ready, remove the cover and bake as directed—add a few extra minutes if starting straight from cold.
- Reheat for Best Texture
When reheating, use either a 350°F (175°C) oven or a toaster oven. Cover lightly with foil to prevent excessive browning, then heat until warmed through and the cheese is bubbly once again.
