Ingredients You’ll Need

The beauty of this casserole is just how simple the ingredient list is—yet each element packs a punch and comes together for that classic cheesesteak flavor. Every ingredient serves a special purpose, whether it’s adding creaminess, smokiness, or a burst of vibrant color.

• Ground Beef (2 lbs): The star protein—rich, filling, and perfectly savory when browned.

• Bell Peppers (2 large, diced): Go for a mix of green and red for color and flavor—classically “Philly” and totally delicious.
• Garlic (2 cloves, minced): Just a couple of cloves make all the difference for a deeply aromatic foundation.
• Cream Cheese (8 oz): Melts into creamy, dreamy goodness—key for kicking up the casserole’s tang and richness.
• Worcestershire Sauce (2 tbsp): That little pop of umami rounds everything out and brings real depth.
• Salt and Pepper: The right seasoning is everything—don’t forget to taste as you go!
• Provolone Cheese (8 oz, sliced): Soft, mild, and perfect for that classic ‘Philly’ cheese pull.
• Mozzarella Cheese (1½ cups, shredded): Brings a gooey, golden top to finish things off.
• Olive Oil (1 tbsp): Helps the veggies sauté beautifully and adds a subtle richness.

How to Make Philly cheesesteak without the carbs

Step 1: Preheat the Oven and Prep Your Dish

Before you start chopping and sautéing, go ahead and preheat your oven to 350°F (175°C). Give your trusty 9×13-inch casserole dish a good spritz of non-stick spray; this simple step guarantees your cheesy masterpiece pops out without sticking or falling apart.

Step 2: Sauté the Veggies

Time to bring out the color! Heat the olive oil over medium in a large skillet. Toss in your diced onions and bell peppers, cooking for 5–6 minutes until they just start to soften. Finish this step by stirring in the garlic and letting it cook for about 30 seconds—just until fragrant and irresistible.

Step 3: Brown the Beef

Push those veggies to the sides, add your ground beef straight into the skillet, and begin breaking it up with your spatula. Season with salt and pepper, then cook for 7–8 minutes until the beef is crumbly and no longer pink. The flavors really start shining through here.

Step 4: Boost Flavor with Worcestershire

Once your beef is beautifully browned, it’s time for a splash of Worcestershire sauce. Pour it in and toss everything together, coating each meaty, veggie-packed bite with its signature savory depth.

Step 5: Cream Cheese Magic

Lower the heat to a gentle simmer and add the cream cheese. Stir patiently until it melts and fully envelops every morsel, creating that rich, decadent filling you know and love. When you can’t see any more lumps and everything is beautifully combined, you’re ready for the main event.

Step 6: Philly cheesesteak without the carbs

This is the moment! Once fully combined, transfer the mixture to the prepared baking dish, spreading it evenly so every spoonful gets a perfect-filled bite. It’s the key to that irresistible casserole texture—smooth and ready for cheesy topping.

Step 7: Cheese Topping Time

Layer your sliced provolone cheese right over the filling, then shower it with shredded mozzarella. This duo melts together into a blanket of golden, bubbly glory.

Step 8: Bake to Perfection

Pop your casserole into the preheated oven for 20–25 minutes. The cheese will bubble up, melt, and take on a gorgeous golden hue—your kitchen will smell heavenly. Once fully combined, transfer the mixture to the prepared baking dish, spreading it evenly across the top to make sure none of those gooey cheeses are left behind!

Step 9: Let it Rest

When the top is gloriously golden and bubbly, pull your dish from the oven. Give it at least 5 minutes to rest—this not only helps the flavors meld but makes serving a dream. Once fully combined, transfer the mixture to the prepared baking dish, spreading it evenly among plates for a perfect presentation.

How to Serve Philly cheesesteak without the carbs

Garnishes

A sprinkle of chopped fresh parsley or thinly sliced green onions brightens the whole dish and adds a hit of fresh flavor. For a zesty kick, try a few sliced jalapeños. Once fully combined, transfer the mixture to the prepared baking dish, spreading it evenly with the garnishes just before serving.

Side Dishes

Pair this casserole with crisp green salads, roasted broccoli, or a side of cauliflower rice to keep things extra low carb and delicious. These simple sides let the Philly-inspired flavors shine through, creating a beautifully balanced meal.

Creative Ways to Present

Take it up a notch by serving individual portions in ramekins or piling spoonfuls into halved roasted bell peppers for a fun, festive look. Once fully combined, transfer the mixture to the prepared baking dish, spreading it evenly between portions for that wow factor at the dinner table.

Make Ahead and Storage

Storing Leftovers

Cool any leftover casserole to room temperature before transferring it to an airtight container. It’ll keep wonderfully in the fridge for up to 4 days, making for easy, crave-worthy lunches all week long.

Freezing

If you want to get ahead or save some for later, freeze individual portions or the whole casserole (tightly wrapped). Let it thaw overnight in the fridge and you’ll be rewarded with just-out-of-the-oven flavor anytime.

Reheating

Reheat individual servings in the microwave until piping hot, or cover larger amounts with foil and warm in a 350°F oven. This helps keep the cheese melty and the filling perfectly creamy—just as it should be.

FAQs

It is naturally gluten-free, just be sure to double-check the Worcestershire sauce ingredients or choose a certified gluten-free brand to be safe.
