Ingredients You’ll Need

• Ground Beef: Go for 85% lean for rich flavor and the perfect juicy bite.
• Bell Pepper: Chopped bell pepper brightens things up and gives an authentic cheesesteak taste.
• Onion: A small onion adds sweetness and depth—don’t skip it!
• Salt: Seasons everything and ties all the layers together.
• Garlic Powder: Infuses every mouthful with savory warmth, no chopping needed.
• Onion Powder: Doubles up on sweet onion flavor, blending into the meat beautifully.
• Pepper: Just a touch for the tiniest kick.
• Worcestershire Sauce: A splash ramps up the umami, making the beef even more craveable.

• Provolone Cheese: The classic finishing touch—six creamy slices for a perfectly gooey golden top.

How to Make Philly Cheesesteak Casserole

Step 1: Preheat and Prep

Start by preheating your oven to 350 degrees and greasing an 8×8-inch casserole dish. This ensures your Philly Cheesesteak Casserole won’t stick, making for tidy slices and effortless serving later on.

Step 2: Brown the Beef and Veggies

Grab your favorite large skillet and place it over medium-high heat. Toss in the ground beef, chopped bell pepper, and onion. As the beef cooks, use a spoon to break it up so you get those nice, small bites that mix beautifully with the veggies. You’re looking for the beef to be fully browned and the veggies tender, releasing all their sweet and savory flavor.

Step 3: Drain, Then Season and Cream

Once everything’s browned and mingled, carefully drain off any extra fat from the skillet (a crucial step for casserole texture!). Return the mixture to the heat and add your salt, garlic powder, onion powder, and pepper. Pour in the Worcestershire sauce for that unmistakable savory punch, then stir in the cream cheese. As the cream cheese melts, it creates a luscious, velvety sauce that’s signature to this dish!

Step 4: Assemble in the Casserole Dish

Spoon the beef and veggie mixture into your prepared casserole dish. Spread it in an even layer so every corner gets a bit of that flavor-packed filling. Layer your provolone cheese slices over the top—it’s okay if they overlap, since they’ll melt together into one dreamy, gooey blanket.

Step 5: Bake to Perfection

Slide your casserole into the oven and bake at 350 degrees for about 15 minutes. The cheese should be melting, bubbly, and just starting to turn a gorgeous golden color. Trust us, the aroma will have everyone asking when dinner’s ready!

How to Serve Philly Cheesesteak Casserole

Garnishes

Sprinkle a little chopped fresh parsley or sliced green onions over the top of your Philly Cheesesteak Casserole before serving. Not only does this add a punch of color, but it also brings fresh, bright flavor to every bite.

If you’re serving a crowd, try scooping your Philly Cheesesteak Casserole onto mini sandwich rolls for a playful, party-ready twist. Or, create individual ramekins for a sit-down dinner where everyone gets their own bubbling-hot portion.

Make Ahead and Storage

Storing Leftovers

Leftover Philly Cheesesteak Casserole keeps beautifully in the fridge. Just cover the dish tightly with foil or transfer slices to an airtight container—plan to enjoy within 3 or 4 days while everything is still at its best.

Freezing

If you want to save some for a rainy day, this casserole is freezer friendly. Cool it completely, wrap well in plastic and foil, and freeze for up to 2 months. Thaw overnight in the fridge for an easy heat-and-eat dinner later on.

Reheating

For reheating, cover with foil and warm in a 350-degree oven until hot and bubbly, or microwave individual portions for a speedy lunch. If you like your cheese extra melty, give it a quick broil at the end.

FAQs

Can I use a different type of meat?

Absolutely! While ground beef is classic, ground turkey or chicken also work nicely and even lighten things up a bit.

Is there a way to make this Philly Cheesesteak Casserole gluten-free?

Yes! All the main ingredients are naturally gluten-free, but double-check your Worcestershire sauce label. Pair with your favorite gluten-free sides or breads for a complete meal.

Can I add mushrooms or other veggies?

Definitely! Sliced mushrooms, sautéed spinach, or even jalapeños can add extra personality and flavor—feel free to make it your own.

What’s the best way to prevent the casserole from getting greasy?

Drain the browned beef and veggie mix thoroughly before adding to the dish. Using a slightly leaner beef (like 85–90% lean) also helps keep it balanced.

Is this casserole spicy?

By default, Philly Cheesesteak Casserole isn’t spicy. If heat is your thing, try adding a pinch of red pepper flakes or swapping in a spicy cheese for some of the provolone.

Final Thoughts
