Ingredients You’ll Need

The magic of this casserole lies in its simple, wholesome ingredients that come together effortlessly. Each one enhances the dish’s robust flavor profile, contributing essential textures, creaminess, and that signature Philly cheesesteak vibe.

2 lbs ground beef: The hearty base that brings meaty flavor and satisfying protein.
1 large onion, diced: Adds sweetness and a bit of crunch to brighten the dish.
2 large bell peppers, diced: Choose green, red, or a mix for vibrant color and fresh flavor.
2 cloves garlic, minced: Delivers fragrant depth that complements the savory beef.
8 oz cream cheese: Creates luscious creaminess that binds the casserole together.
2 tbsp Worcestershire sauce: Boosts umami and adds that classic tangy note.
Salt and pepper to taste: Essential for seasoning and highlighting all the flavors.
8 oz provolone cheese, sliced: Melts beautifully to provide a smooth, mild cheesiness.
1½ cups mozzarella cheese, shredded: Offers a stretchy, gooey topping that browns nicely in the oven.
1 tbsp olive oil: For sautéing vegetables and enhancing their natural sweetness.

How to Make Low Carb Philly Cheesesteak Casserole Recipe

Step 1: Prepare the Oven and Pan

Start your cooking journey by preheating your oven to 350°F (175°C). Lightly spray a 9×13-inch baking dish with non-stick spray to ensure your delicious casserole slides right out after baking without any fuss.

Step 2: Cook the Vegetables

In a large skillet over medium heat, warm the olive oil and toss in your diced onions and bell peppers. Cook these for 5 to 6 minutes until they start to soften and release their natural sweetness. Add the minced garlic last and sauté it for about 30 seconds, just until the aroma fills your kitchen, signaling it’s time for the next step.

Step 3: Brown the Ground Beef

Now, add the ground beef to the skillet with your veggies. Season with salt and pepper, then break it apart with a spatula, letting it brown evenly. Cook for around 7 to 8 minutes until there’s no pink left, and the meat has developed a rich, savory color.

Step 4: Add Worcestershire Sauce

Drizzle in the Worcestershire sauce and stir well so every morsel gets coated. This tangy addition truly elevates the depth of flavor and brings a subtle, signature bite to this Philly-inspired dish.

Step 5: Incorporate Cream Cheese for that Smooth Finish

Turn the heat down low and add the softened cream cheese. Stir continually until it melts into the beef mixture, creating a silky, creamy texture that makes this casserole irresistibly rich.

Step 6: Once fully combined, transfer the mixture to the prepared baking dish, spreading it evenly

This step is a game changer. Take the luscious meat and veggie mixture and once fully combined, transfer the mixture to the prepared baking dish, spreading it evenly. This even layer is crucial for balanced cooking and makes sure every bite contains the perfect mix of flavors and textures.

Step 7: Layer the Cheeses

Next, place the sliced provolone cheese over the mixture in an even layer, followed by a generous sprinkling of shredded mozzarella. The cheeses will melt spectacularly in the oven, forming that golden, bubbly, luscious top everyone loves.

Step 8: Bake until Bubbly and Delicious

Place your casserole in the preheated oven and bake for 20 to 25 minutes. You want the cheese to be melted, bubbly, and lightly golden. It’s the moment when all your hard work comes together into a warm, cheesy masterpiece.

Step 9: Rest and Enjoy

Before serving, let the casserole rest for 5 minutes. This brief pause helps meld the flavors even more and makes slicing easier, so you get perfect portions every time.

Garnishes

To make your presentation pop, sprinkle some freshly chopped parsley or green onions on top. These garnishes add a fresh, vibrant contrast that brightens the rich casserole beautifully, inviting everyone to dig in.

Side Dishes

This casserole is satisfying enough to stand on its own, but pairing it with a crisp green salad or roasted vegetables adds a refreshing balance. For a low-carb meal, consider buttery garlic asparagus or steamed broccoli for color and nutrition.

Creative Ways to Present

Try serving individual portions in small ramekins straight from the oven for a homey touch. Or layer the casserole over a bed of cauliflower rice for an extra boost of veggies and a complete low-carb experience that feels hearty yet light.

Make Ahead and Storage

Storing Leftovers

Once cooled, cover any leftover casserole tightly with foil or transfer to an airtight container. Store in the refrigerator for up to 3 days. The flavors deepen over time, making leftovers just as delicious as the first serving.

Freezing

This dish freezes wonderfully. After baking, let it cool completely, then cover it well with plastic wrap and foil before placing in the freezer. When you want to enjoy it again, thaw it overnight in the fridge before reheating.

Reheating

Reheat your leftovers in the oven at 350°F until warmed through and the cheese is bubbly again. Alternatively, microwave individual portions for 2-3 minutes on medium power, checking to make sure it’s heated evenly without drying out.

FAQs

Can I use a different type of cheese in this casserole?

Absolutely! Cheddar, Monterey Jack, or even pepper jack can add interesting twists. Just keep the melty, creamy texture as your goal for that perfect cheesesteak feel.

Is this casserole suitable for gluten-free diets?

Yes! All the ingredients are naturally gluten-free, making it a safe and delicious option for those avoiding gluten.

Can I substitute ground beef with another protein?

You can swap ground beef for ground turkey or chicken for a lighter version, but the flavor and richness might be slightly different. Ground pork also works well if you like a fattier taste.

How spicy is this casserole?

This version is mild and focuses on savory, cheesy goodness. To add heat, try mixing in sliced jalapeños or a dash of hot sauce before baking.

What can I do if I don’t have Worcestershire sauce?

If you’re out, try substituting with soy sauce or coconut aminos for comparable umami. A splash of balsamic vinegar mixed with a pinch of soy sauce also brings a nice tangy depth.

Final Thoughts

I truly hope you give this Low Carb Philly Cheesesteak Casserole a try. Once fully combined, transfer the mixture to the prepared baking dish, spreading it evenly, and you are well on your way to creating a dish that’s not just comforting and easy but downright addictive.
