How to Make Low Carb Philly Cheesesteak Casserole

Step 1: Preheat and Prepare Your Dish

The perfect casserole starts with a little prep. Preheat your oven to 350°F (175°C). Grab your favorite 9×13 baking dish and coat it with non-stick spray—this ensures that, after all your effort, the finished bake lifts out easily and every cheesy bite is accounted for!

Step 2: Cook the Vegetables

In a large skillet over medium heat, drizzle in that olive oil. Toss in your freshly diced onions and bell peppers, letting them sizzle and soften for 5-6 minutes. When the kitchen smells like a cheesesteak stand, stir in the minced garlic, cooking for just 30 seconds more to release that incredible aroma.

Step 3: Brown the Beef

Now add your ground beef right into the skillet with those perfectly sautéed veggies. Season generously with salt and pepper, breaking up the meat with a spatula as you go. Keep cooking until the beef is nicely browned with no pink bits left—about 7-8 minutes.

Step 4: Add Seasonings

Stir in the Worcestershire sauce, letting it mingle with the beef and veggies. This quick step intensifies all the savory flavors and deepens the meaty richness, giving you that authentic Philly vibe in casserole form.

Step 5: Incorporate the Cream Cheese

Lower the heat and add your cream cheese right into the skillet. Stir lovingly until it’s melted down and every morsel is coated in creamy goodness. The filling will look irresistibly rich and glossy at this stage.

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

Now for the magic moment. Once the meat, veggies, and cream cheese have mingled into a glorious mixture, once fully combined, transfer the mixture to the prepared baking dish, spreading it evenly from corner to corner. This ensures every serving gets the perfect balance of flavor and texture.

Step 7: Add Your Cheese Layers

Arrange the slices of provolone in a delicious blanket atop your beef mixture, followed by an even sprinkle of shredded mozzarella. This irresistible duo will bubble and brown into a golden, cheesy crust during baking.

Step 8: Bake to Perfection

Slide your casserole into the oven and let it bake for 20-25 minutes. The cheese will melt, the top will get beautifully golden, and your kitchen will smell like pure comfort. Don’t forget to let the casserole rest for five minutes before you dig in; this helps everything set up for clean slices.

How to Serve Low Carb Philly Cheesesteak Casserole

Garnishes

A little garnish goes a long way! Once fully combined, transfer the mixture to the prepared baking dish, spreading it evenly, then pop on some freshly chopped parsley or sliced green onions after baking for a touch of color and a fresh finish. For an extra punch, try a few sliced pickled peppers or a light sprinkle of red pepper flakes.

Side Dishes

Nothing pairs better with this hearty casserole than something crisp and bright. A simple green salad or sautéed green beans add balance and crunch. If you want to keep things low-carb but crave a “bread-like” side, serve with roasted cauliflower or almond flour biscuits—each bite soaks up those cheesy, savory juices effortlessly.

Creative Ways to Present

Feel like mixing it up? Once fully combined, transfer the mixture to the prepared baking dish, spreading it evenly, but instead of baking family-style, try putting the filling in individual ramekins for personal mini-casseroles. Or, spoon some casserole into crisp lettuce cups for a fun, hand-held twist that’s perfect for parties.

Make Ahead and Storage

Storing Leftovers

Leftovers are a gift with this recipe! Cover your baking dish tightly or transfer slices into airtight containers. Refrigerate for up to four days—the flavors will deepen and the casserole reheats beautifully.

Freezing

Philly Cheesesteak Casserole freezes like a dream. Once fully combined, transfer the mixture to the prepared baking dish, spreading it evenly, then wrap tightly in foil before baking. Store in the freezer for up to three months. When you’re ready to enjoy, thaw overnight in the fridge and bake as directed.

Reheating

To revive leftover casserole, cover with foil and reheat in a 350°F oven for about 15-20 minutes, or until warmed through. For quick meals, a few minutes in the microwave will do—just watch for bubbling cheesy goodness!

FAQs

Can I use a different type of meat?

Absolutely! While ground beef gives that classic Philly flavor, ground turkey or chicken can lighten things up. You could even use thinly sliced steak for an ultra-authentic feel—just adjust the cooking time as needed.

What bell pepper varieties work best?

Any color you love will work, but a mix of green, red, and yellow offers beautiful color and a hint of sweetness alongside the savory notes. Feel free to experiment with your favorites!

Is it possible to make this dairy-free?

You can absolutely try a dairy-free version! There are great plant-based cream cheese and cheese alternatives—just be sure to choose ones that melt well for that signature creamy texture.

How do I keep the casserole from becoming watery?

Make sure to cook off any excess liquid from your vegetables and beef before mixing in the cheeses. Once fully combined, transfer the mixture to the prepared baking dish, spreading it evenly—this creates the perfect consistency for a set, sliceable bake.

Can this casserole be assembled ahead of time?

Yes, you can do all your prep work in advance. Once fully combined, transfer the mixture to the prepared baking dish, spreading it evenly, then cover and refrigerate. When you’re ready to bake, just add the cheese and pop it straight into the oven!
