Ingredients You'll Need

The bottom layer consists of browned cooked ground meat, with a coarse texture and deep brown color, evenly spread across the pan. On top of this is a thick layer of white, creamy cottage cheese, with smooth and crumbly parts mixed together, covering much of the meat. A dark brown liquid, likely soy sauce or a similar sauce, is being poured with a wooden spoon from the upper right corner onto the white layer, creating a shiny, wet area on the cheese.

The ingredients for this casserole are refreshingly simple but each plays an essential role in building the dish’s satisfying texture, taste, and color. From the rich ground beef to the colorful bell peppers, every component enhances the overall experience.

Ground beef: I like to use 80/20 for juicy, flavorful meat that browns nicely.
Onion: Adds sweetness and a lovely aroma when cooked down.
Bell peppers: They bring color, crunch, and a mild sweetness that balances the meat.
Garlic: Just a couple of cloves to give the dish a subtle punch of flavor.
Cream cheese: This melts into the meat for dreamy creaminess.
Worcestershire sauce: A secret all-star ingredient enhancing the savory notes.
Salt and pepper: Basic seasonings that bring out all the other flavors.
Provolone cheese: Sliced and layered for that authentic Philly cheesesteak feel.
Mozzarella cheese: Shredded for gooey meltiness and irresistible cheese pull.
Olive oil: To sauté the veggies perfectly without sticking.

Directions

Step 1: Preheat your oven to 350°F (175°C) and spray a 9×13 baking dish with non-stick spray so your casserole won’t stick and will come out looking beautiful.

Step 2: Heat the olive oil in a large skillet over medium heat. Add the diced onions and bell peppers and cook for about 5-6 minutes until they start to soften and become fragrant. This step builds the foundational sweetness and aroma for the dish.

Step 3: Stir in the minced garlic and cook for an additional 30 seconds, stirring constantly to prevent it from burning and becoming bitter.

Step 4: Add the ground beef to the skillet, breaking it up with your spatula as it cooks. Season generously with salt and pepper. Cook for 7-8 minutes until the beef is fully browned with no pink left, then drain any excess fat to keep the casserole from being greasy.

Step 5: Stir in the Worcestershire sauce, letting it coat the beef and veggies, intensifying the meaty flavor. Lower the heat to low and add the softened cream cheese, stirring continuously until it melts fully and creates a smooth, creamy texture throughout.

Step 6: Transfer the meat and vegetable mixture to your prepared baking dish, spreading it out evenly. Next, layer torn pieces of provolone cheese evenly over the top, making sure you get good coverage for that classic Philly cheesesteak cheesiness.

Step 7: Sprinkle the shredded mozzarella cheese as the final layer. This will melt beautifully and give you that spectacular stretch when serving.

Step 8: Bake the casserole for 22-25 minutes until the cheese is melted, bubbly, and lightly golden on top. Once out of the oven, let it rest for about 5 minutes to allow the flavors to meld and set, making it easier to serve.

Don’t skip the 5-minute resting time after baking—it really helps the flavors come together beautifully.

I love serving this casserole straight from the oven, hot and bubbly, which makes for the most comforting dining experience. It’s fabulous on its own, but I often like to pair it with a crisp green salad or some roasted low-carb vegetables like asparagus or cauliflower to round out the meal with extra texture and freshness.

For presentation, I like to garnish with some freshly chopped parsley or green onions sprinkled over the top to add a pop of color and a little extra brightness to each plate. Slicing the casserole into neat squares on a large platter makes it feel extra special and is perfect for serving guests or family.

When it comes to drinks, this casserole pairs beautifully with a chilled glass of dry white wine like Sauvignon Blanc or a light beer to balance out the richness. For non-alcoholic options, sparkling water with a splash of lemon or iced tea works wonderfully. I find this dish is incredibly versatile for weeknight dinners, casual get-togethers, and even special occasions when you want something comforting yet a little unique.

Variations

I often switch things up with this Low Carb Philly Cheesesteak Casserole Recipe depending on what I have on hand. If you want a slightly different flavor, swapping provolone for sharp cheddar cheese brings a nice tangy twist that many friends enjoy. You can also add mushrooms to the sautéed veggies for an earthier depth that pairs beautifully with the beef.

If you’re following a gluten-free diet, you’ll be happy to know this recipe is naturally gluten-free as long as you use gluten-free Worcestershire sauce. For my vegan or vegetarian friends, I’ve experimented using plant-based ground “meat” substitutes and dairy-free cream cheese and cheese alternatives. While the texture changes a bit, it still nails the savory, cheesy spirit of the dish!

Cooking method-wise, you could try making this in an air fryer–safe casserole dish for a slightly quicker bake and crispier cheese topping. I love experimenting with these tweaks to keep the recipe flexible and enjoyable every time I make it.

Storage and Reheating

Storing Leftovers

Leftovers from this casserole store beautifully in an airtight container in the refrigerator for up to 4 days. I prefer using glass containers for easier reheating and to keep the flavors fresh. Make sure the casserole has cooled close to room temperature before sealing to prevent excess moisture inside.

Freezing

You can definitely freeze this dish! I recommend portioning the casserole into individual airtight containers or freezer-safe zip-lock bags. It keeps well for up to 3 months. When freezing, I label the containers with the date for easy reference. Thaw overnight in the fridge before reheating for best results.

Reheating

For reheating, I find the oven works best to bring back that melty cheesiness and to avoid sogginess—simply cover the casserole with foil and warm it at 325°F (160°C) for 15-20 minutes until heated through. Microwaving is fine in a pinch but can sometimes make the cheese rubbery, so if you go that route, heat in short bursts and stir gently.

FAQs

Can I use other types of meat in this casserole?

Absolutely! While ground beef gives the casserole its classic feel, you can substitute with ground turkey or chicken for a leaner option. Just be mindful these meats tend to be less fatty, so you might want to add a little olive oil while cooking to keep the mixture moist and flavorful.

Is this recipe suitable for meal prep?

Definitely! This Low Carb Philly Cheesesteak Casserole Recipe is fantastic for meal prepping because it holds up well in the fridge and reheats nicely. You can portion it out into containers for a quick grab-and-go dinner during busy weeks.

Can I add other vegetables to the casserole?

Yes, feel free! Mushrooms, spinach, or even small diced zucchini can be great additions. Just add them to the skillet when cooking the onions and peppers to soften and blend their flavors with the beef.

How can I make this recipe spicier?

If you like heat, consider adding some sliced jalapeños with the bell peppers or sprinkling red pepper flakes into the meat mixture. Another option is topping the finished casserole with a spicy hot sauce or drizzle of sriracha for an extra kick.

What’s the best way to get that gooey cheese pull in the casserole?

The combination of provolone slices and shredded mozzarella creates the perfect melted cheese pull. Make sure the cheeses are layered evenly and baked until bubbly and golden on top. Letting the casserole rest a few minutes after baking also helps the cheese set just right for that dreamy stretch with every bite.
