Ingredients You’ll Need

Each ingredient in this recipe works in harmony to deliver the comfort food vibe you crave but with a low carb twist. Picking quality ingredients, like good ground beef and fresh peppers, really makes the flavors pop, so I always recommend shopping with that in mind.

• Ground beef: I prefer 80/20 fat for that juicy, flavorful base that keeps the casserole moist and rich.
• Onion: Adds a sweet, aromatic layer—diced finely so it cooks down perfectly.
• Bell peppers: Green, red, or a mix—these bring color, crunch, and a bit of natural sweetness.
• Garlic: Minced fresh garlic gives this dish that savory punch you’ll love.
• Cream cheese: Softened to smooth, it melts into the meat for creaminess without carbs.
• Worcestershire sauce: A little umami magic that deepens the meaty flavor.
• Salt and pepper: Essential for seasoning—don’t be shy here, because they bring everything together.
• Provolone cheese: Sliced for layering, it melts beautifully with just a bit of tang.
• Mozzarella cheese: Shredded mozzarella adds that stretchy, melty goodness everyone loves.
• Olive oil: For sautéing the veggies, adds a subtle fruity note and keeps things from sticking.

Variations

I love how flexible this Low Carb Philly Cheesesteak Casserole Recipe is. Depending on what’s in your kitchen or your personal taste, it’s super easy to tweak. Feel free to experiment—you might find your new favorite twist.

• Spicy kick: I sometimes add a pinch of crushed red pepper flakes or swap in pepper jack cheese to give it some heat—adds a fun surprise with every bite.
• Mushroom lovers: Adding sautéed mushrooms is a great way to increase the veggie count and get a deeper, earthier flavor.
• Cheese swap: If provolone isn’t your thing, swapping in Swiss or even cheddar offers a nice change in taste while keeping that melty texture.
• Dairy-free tweak: You can swap cream cheese for a dairy-free alternative and skip on mozzarella, maybe use nutritional yeast for flavor if you’re sensitive.

How to Make Low Carb Philly Cheesesteak Casserole Recipe

Step 1: Prep and Sauté Your Veggies

Start by heating your olive oil in a large skillet over medium heat. Toss in the diced onions and bell peppers, and let them soften for about 5–7 minutes. You’re looking for tender, slightly caramelized veggies that bring sweetness and crunch. Add the minced garlic in the last minute so it doesn’t burn but releases its aroma.

Step 2: Brown the Ground Beef

Push those veggies to the side and add your ground beef to the skillet. Break it up with your spatula, and cook until it’s fully browned with no pink spots remaining—usually about 8 minutes. As it cooks, sprinkle in salt, pepper, and Worcestershire sauce to build a deep, savory flavor. Once done, mix the veggies back in and drain off excess fat if needed to keep the casserole from getting greasy.

Step 3: Add Cream Cheese and Mix

Reduce the heat to low, and add your softened cream cheese directly into the skillet. Stir it in gently until you have a creamy mixture coating the meat and veggies evenly—that’s where the magic happens to make this casserole rich without any heavy carbs.

Step 4: Assemble and Layer the Cheese

Transfer the beef mixture to your casserole dish and smooth it out nicely. Layer the provolone slices evenly over the top, then sprinkle the shredded mozzarella on top of that for a bubbly, melty finish.

Step 5: Bake Until Golden and Melted

Bake your casserole in a preheated oven at 375°F (190°C) for about 15-20 minutes, or until the cheese is fully melted and starting to turn golden brown. Keep an eye on it during the last few minutes so it doesn’t overcook—melty and gooey is the goal here!

How to Serve Low Carb Philly Cheesesteak Casserole Recipe

Garnishes

I love topping my casserole with a sprinkle of fresh chopped parsley or some thinly sliced green onions. They add a pop of color and a fresh brightness that contrasts beautifully with the rich cheese and beef. Sometimes, a dash of hot sauce on the side is just the cherry on top for me.

Side Dishes

Since the casserole is pretty hearty, I like to pair it with a crisp green salad or steamed broccoli to add a fresh, crunchy balance. Roasted asparagus or even cauliflower rice work well, keeping the meal low-carb but satisfying.

Creative Ways to Present

For parties, I’ve served this Low Carb Philly Cheesesteak Casserole Recipe in mini ramekins or even as stuffed bell peppers, which makes it extra fun and visually appealing. It’s a great way to upscale comfort food and impress your guests while keeping it simple.

Make Ahead and Storage

Storing Leftovers

I usually store leftovers in an airtight container in the fridge for up to 3 days. Reheating it works best in the oven or air fryer to keep that beautiful melted cheese texture, but the microwave is totally fine if you’re short on time.

Freezing

This casserole freezes beautifully—just cool it completely, portion out into freezer-safe containers, and freeze for up to 2 months. When you want to enjoy it again, thaw overnight in the fridge before reheating.

Reheating

My favorite way to reheat is popping it in a 350°F oven for about 10-15 minutes, covered loosely with foil so it doesn’t dry out. If in a pinch, the microwave works too; just cover it to keep moisture in and heat in 30-second bursts to avoid rubbery cheese.
