One of the things that really makes this Easy Philly Cheesesteak Casserole Recipe stand out is how well the simple ingredients come together, especially the Bisquick base for that soft, biscuit-like crust that soaks up all the beefy, cheesy goodness. It’s also a brilliant dish to bring to gatherings because it feeds a crowd and tastes even better the next day. Trust me, once you try it, you’ll want to keep this one in your weekly rotation!

Ingredients You’ll Need

These ingredients work together beautifully to create a cozy, flavorful casserole that’s satisfyingly rich but still straightforward. Here’s a quick tip: opt for fresh, sweet onions and green peppers to really lift the savory beef, and don’t skip the provolone — it melts perfectly and adds that signature cheesesteak touch.

Bisquick mix: Provides a quick biscuit base that’s tender yet sturdy enough to hold all the layers.
Milk: Adds moisture and helps create a soft dough with the Bisquick.
Large egg: Acts as a binder for the crust, keeping it from getting crumbly.
Ground black pepper: Divided use allows seasoning the meat and the crust for balanced flavor.
Ground beef: The heart of the dish; choose 80/20 for best flavor and juiciness.
Sweet onion (sliced): Adds a natural sweetness that complements the beef perfectly.
Green bell pepper (sliced): Brings freshness and crunch to balance the richness.
Brown gravy mix: Thickens and seasons the filling, keeping it moist and savory.
Water: Used to prepare the gravy, blending all the flavors together.
Provolone cheese slices: Melts beautifully over the top, mimicking that classic Philly cheesesteak cheese pull.

Variations

I love mixing this recipe up to keep it fresh — it’s perfect for playing around based on what you have on hand or your personal preferences. Feel free to swap out ingredients or add a little extra spice!

Using sliced steak instead of ground beef: If you want authenticity, thinly sliced ribeye works wonderfully; just adjust the cooking time to avoid overcooking.
Add more veggies: Sometimes I throw in mushrooms or banana peppers for extra flavor and texture.
Spicy kick: Add a pinch of crushed red pepper flakes when cooking the meat if you like a little heat.
Cheese swap: Sharp cheddar or Monterey Jack can work if provolone isn’t your thing, though provolone is my fave.
Make it low-carb: Skip the Bisquick crust and serve the filling over cauliflower rice or roasted veggies.

How to Make Easy Philly Cheesesteak Casserole Recipe

Step 1: Whip Up the Bisquick Crust

Start by preheating your oven to 350°F (175°C). In a bowl, combine 2 cups of Bisquick mix with 1 cup of milk, one large egg, and half a teaspoon of ground black pepper. Stir everything together until it forms a sticky dough — don’t overmix or it can get tough. Press this mixture evenly into the bottom of a greased 9×13-inch baking dish. This crust will give you that soft, biscuit-like base that’s just right for soaking up all that melty goodness.

Step 2: Cook the Beef and Veggies

In a large skillet over medium heat, brown 2 pounds of ground beef along with sliced sweet onions and green bell peppers until the beef is no longer pink and veggies are tender, about 8-10 minutes. Season the meat with the remaining half teaspoon of black pepper as it cooks. Drain excess fat if needed — you want the mixture juicy but not greasy.

Step 3: Make the Gravy and Combine

Mix your brown gravy packet with 1 cup water until smooth, then pour it into the skillet with the beef and vegetable mixture. Let it simmer for a few minutes so the gravy thickens and the flavors meld beautifully. This savory sauce is what ties everything together in this Easy Philly Cheesesteak Casserole Recipe.

Step 4: Layer and Bake

Spread the beef and veggie mixture evenly over the Bisquick crust in your baking dish. Next, layer 11 slices of provolone cheese across the top so every bite will have that gooey cheesesteak feeling. Bake the casserole uncovered in your preheated oven for 25-30 minutes until the crust is golden and the cheese is melted and bubbly. Let it cool for 5 minutes before serving to make slicing easier and to avoid burning your mouth (lesson learned the hard way!).

Garnishes

I like topping my slices with a little extra green onion or chopped parsley to add freshness and color. A drizzle of hot sauce or a dollop of sour cream can also add some zing if you’re feeling adventurous. These simple touches make the whole dish pop and feel a little more special.

Side Dishes

This casserole holds up really well with lighter sides like a crisp garden salad or roasted broccoli to balance out the richness. If you want to keep it casual, some crispy oven fries or even pickles on the side are classic pairing choices that complement the flavors beautifully.

Creative Ways to Present

For potlucks or family dinners, I like serving this Easy Philly Cheesesteak Casserole Recipe in individual ramekins so everyone gets their own cheesy, meaty portion. It’s also fun to sprinkle extra shredded provolone on top before baking for a golden, crispy cheese crust. For a cozy winter meal, add some crusty bread on the side to sop up all those delicious juices.

Make Ahead and Storage

Storing Leftovers

Once cooled, I store leftovers in an airtight container in the fridge for up to 3 days. It keeps really well and tastes fantastic reheated. Just be sure to cover it tightly so it doesn’t dry out.

Freezing

I’ve successfully frozen this casserole both before and after baking. When freezing before baking, wrap the dish tightly with foil and plastic wrap, then thaw overnight before baking as usual. For baked leftovers, portion it out into freezer-safe containers. Just thaw in the fridge overnight before reheating.

Reheating

Reheat leftovers covered with foil in a 350°F oven for about 15-20 minutes until warmed through. If you’re in a hurry, the microwave works too—just cover loosely and heat in 1-minute intervals to keep the cheese from overheating and separating.

FAQs

Can I use other types of cheese in this Easy Philly Cheesesteak Casserole Recipe?

Absolutely! While provolone cheese gives that classic Philly cheesesteak flavor, you can use Swiss, mozzarella, or even cheddar if you prefer a sharper taste. Just choose cheeses that melt well for the best texture.
Is ground beef the best meat option?

Ground beef is easy and convenient, but you can swap it for thinly sliced ribeye or sirloin for a more authentic Philly cheesesteak experience. Just be sure to cook the slices quickly so they stay tender.
Can I make this recipe gluten-free?

To keep the recipe gluten-free, substitute the Bisquick mix with a gluten-free baking mix that’s suitable for biscuits. Also, check that the brown gravy mix you use is gluten-free, or make your own gravy from scratch.
How do I prevent the crust from getting soggy?

Press the Bisquick mixture firmly and evenly into the pan, and avoid adding too much liquid when preparing the gravy. Also, letting the casserole rest a few minutes before cutting helps the crust firm up nicely.
Can I prepare this recipe ahead of time?

Definitely! Assemble the casserole up to the baking step, cover tightly, and refrigerate for up to 24 hours before baking. This makes it a perfect meal prep option for busy weeks.
