How to Make Low Carb Philly Cheesesteak Casserole

Step 1: Prepare the Oven

Set your oven to preheat at 350°F (175°C). Give your 9×13 baking dish a light coating of non-stick spray. Trust me—this little step guarantees everything lifts out easily and looking gorgeous when it’s done!

Step 2: Cook the Vegetables

In a large skillet, warm up that olive oil over medium heat. Toss in the diced onions and bell peppers, stirring occasionally until they begin to soften and their colors turn vivid and inviting—about 5-6 minutes. Add the garlic and cook for just 30 seconds more, enough to release its glorious aroma without burning.

Step 3: Brown the Beef

Now, add your ground beef straight into the skillet with those softened veggies. Season generously with salt and pepper. Break up the meat as it cooks, browning it thoroughly for 7-8 minutes until no pink remains and everything is beautifully combined.

Step 4: Add Seasonings

Pour in the Worcestershire sauce and give it a good stir. This creates that unmistakable cheesesteak flavor, blending richness and tang into every bite.

Step 5: Incorporate Cream Cheese

Turn the heat down low and add your cream cheese right into the pan. Gently stir until it’s melted and envelops everything in creamy, decadent goodness. This step is where the casserole goes from tasty to wow-worthy!

Step 6: Transfer to Baking Dish

Spoon that creamy beef and veggie mixture into your prepared baking dish. Spread it out into an even layer so every slice gets a perfect portion of everything.

Step 7: Top with Cheese

Lay the provolone slices over the beef mixture, making sure to cover it fully. Then, scatter the shredded mozzarella over the top. This double-cheese layer is pure bliss once melted and golden.

Step 8: Bake to Perfection

Pop your masterpiece into the preheated oven and bake for 20-25 minutes. You’ll know it’s ready when the cheese is perfectly melted, bubbling contentedly, and tinged with a light golden edge.

Step 9: Rest Before Serving

Let the casserole rest for five minutes before you dive in. This short wait rewards you with a dish that slices neatly and lets all those robust Low Carb Philly Cheesesteak Casserole flavors come together beautifully.

How to Serve Low Carb Philly Cheesesteak Casserole

Garnishes

Sprinkle fresh chopped parsley or sliced green onions right over the top for a pop of color and extra freshness. For a little heat, a dusting of crushed red pepper or pickled jalapeños can add some zest that pairs wonderfully with all that gooey cheese.

Side Dishes

Low Carb Philly Cheesesteak Casserole is plenty satisfying on its own, but if you want to round out your meal, try serving it with a side of roasted broccoli, a crisp green salad, or even cauliflower rice. These sides keep things light and fresh without overwhelming the star of the show.

Creative Ways to Present

Spoon the casserole filling into hollowed bell pepper halves before baking for built-in edible bowls; or, for individual portions, divide it among ramekins. Either route makes an impressive lunch or party offering that guests won’t forget!

Make Ahead and Storage

Storing Leftovers

Got leftovers? Lucky you! Let the casserole cool to room temperature, then cover the dish with foil or transfer portions to airtight containers. It will keep happily in your fridge for 3-4 days without losing its creamy texture or flavor.

Freezing

This Low Carb Philly Cheesesteak Casserole freezes beautifully. Wrap individual portions tightly or use a freezer-safe container. It’ll keep well for up to 2 months. Just let it thaw overnight in the fridge before reheating for best results.

Reheating

To reheat, cover your casserole with foil and warm it up in a 350°F oven until heated through (about 15 minutes for a family-sized portion, less for individual servings). Or, pop a slice in the microwave for a quick fix—the cheese will melt all over again!

As written, the casserole is mild and family-friendly. For extra kick, mix in diced jalapeños with the veggies or add a pinch of cayenne to the meat mixture before baking.
