Ingredients You’ll Need

Every ingredient here plays a simple, important role in capturing the classic Philly cheesesteak flavor while building this casserole’s rich texture. I like to keep the components straightforward for easy shopping, but quality definitely makes a difference.

• Bisquick mix: This shortcut mix gives the casserole a fluffy, biscuit-like base—far quicker than making dough from scratch.
• Milk: Makes the batter smooth and tender; whole milk works best if you want richness.
• Large egg: Helps bind the batter together for that perfect cakey texture.
• Ground black pepper: Divided between the batter and beef, it adds the right kick without overpowering the dish.
• Ground beef: The heart of the dish—go lean or just moderately fatty; it browns beautifully and brings savory depth.
• Sweet onion: Thinly sliced, it softens as it cooks and offers subtle sweetness to balance the savory beef.
• Green bell pepper: Adds color and crunch, plus a fresh, slightly bitter edge that cuts through the richness.
• Brown gravy mix: This ties the beef and veggies together with a savory sauce that’s key for moist, flavorful layers.
• Water: To prepare the gravy—just enough to keep everything tender and saucy.
• Provolone cheese slices: Classic in Philly cheesesteaks, these melt perfectly and spread creamy cheesiness throughout the casserole.

Variations

I love making this Easy Philly Cheesesteak Casserole Recipe my own by tweaking ingredients or adding extra layers of flavor. Don’t be shy about tailoring it to what your family craves—you might find your own favorite spin!

• Cheese swap: Sometimes I toss in pepper jack or mozzarella for a different cheese flavor and melt factor.
• Veggie add-ins: Mushrooms or sliced jalapeños add a punch and earthiness if you like a bit more texture and spice.
• Meat alternatives: Try ground turkey or chicken for a leaner dish, though I personally prefer the savoriness of beef here.
• Make it low carb: Skip the Bisquick and use cauliflower rice for the base layer; it changes the texture but still delivers on flavor.

How to Make Easy Philly Cheesesteak Casserole Recipe

Step 1: Whip up your Bisquick batter

Start by mixing 2 cups of Bisquick mix with 1 cup of milk, one large egg, and half a teaspoon of ground black pepper. Stir just until combined—don’t overmix, or your base could get tough. The batter should be creamy but pourable. I like to set this aside while I prepare the beef mixture so it doesn’t settle too long.

Step 2: Cook your beef, onions, and peppers

Heat a large skillet over medium-high heat and crumble in the ground beef. Sprinkle with the remaining black pepper as it starts to brown. Once it’s halfway cooked, toss in the sliced sweet onion and green bell pepper. These soften in the beef’s juices, releasing a wonderful aroma. Cook everything until the beef is fully browned and the veggies are tender but not mushy.

Step 3: Make the gravy to bind flavors

In a small bowl, whisk together the brown gravy mix with 1 cup of water. Pour this into the beef and vegetable mixture. Stir and let it simmer until the sauce thickens—this keeps the casserole moist and infuses it with that classic savory Philly cheesesteak taste.

Step 4: Assemble and layer your casserole

Grease a casserole dish and pour half of the Bisquick batter evenly on the bottom. Then, spread the beef mixture over the batter layer. Lay 11 slices of provolone cheese over the beef—don’t skip this step, the cheese melts into gooey perfection. Top with the remaining batter, smoothing it out gently to cover everything.

Step 5: Bake until golden and bubbly

Pop the casserole into a preheated 350°F oven and bake for about 30 to 40 minutes. You’re aiming for a golden crust on top, and bubbly, melted cheese nestled inside. Let it rest for a few minutes out of the oven before slicing—that helps it set, making serving a breeze.

How to Serve Easy Philly Cheesesteak Casserole Recipe

Garnishes

I love topping mine with freshly chopped parsley or green onions—they add a pop of color and a bright, fresh note that balances the richness. A little drizzle of spicy mustard or a few dashes of hot sauce also kick things up if you’re into that kind of heat.

Side Dishes

Since the casserole is pretty filling on its own, I usually go for simple sides—the classic crisp Caesar salad, roasted veggies, or even some garlic bread rounds out the meal nicely. For a real treat, crispy oven-baked fries on the side hit the spot.

Creative Ways to Present

For casual get-togethers, I’ve served this casserole in a large cast-iron skillet to keep it warm and rustic. Another fun twist is turning it into individual portions by baking in muffin tins—great for parties and easy to grab on the go!

Make Ahead and Storage

Storing Leftovers

Leftovers store beautifully in an airtight container in the fridge for up to 3 days. When I pack it up, I make sure it’s completely cooled to avoid sogginess. It reheats wonderfully without losing much of its fresh-baked taste.

Freezing

I’ve frozen this casserole a couple times for busy weeks—just cover it tightly with foil and pop it in the freezer before baking. When you’re ready, thaw overnight in the fridge then bake as usual. The flavors stay intact, and it’s a total lifesaver on hectic nights.

Reheating

To reheat, I prefer the oven at 350°F for about 15-20 minutes to bring back the casserole’s crispy top and gooey center. Microwaving is quicker, but you might lose that lovely texture. If I’m in a rush, covering the dish loosely with a microwave-safe lid helps keep moisture in.
