Ingredients You’ll Need

Embracing a simple ingredient list, this Philly Cheesesteak Casserole lets each component shine, **from the juicy beef to the creamy cheeses**. Every ingredient serves a delicious purpose, combining to create layers of flavor and irresistible texture.

Ground beef or thinly sliced steak (1 pound): The star of the dish—choose ribeye for a classic Philly taste or ground beef for ease and richness.
Olive oil (1 tablespoon): Helps sauté the veggies and adds a subtle, fruity note.
Green bell pepper (1, diced): Adds that essential pop of Philly cheesesteak color and a sweet crunch.
Small onion (1, diced): Gives aromatic depth and classic savory-sweetness.
Garlic (1 clove, minced): Just one clove infuses the dish with a big flavor punch.
Salt (1/2 teaspoon): Balances and enhances every bite.
Black pepper (1/4 teaspoon): Adds mild warmth; feel free to add extra if you like more kick.
Cream cheese (4 oz, softened): The secret to luscious, creamy texture—let it soften so it blends easily.
Sour cream (1/2 cup): Adds tang and helps create the casserole’s signature creamy base.
Worcestershire sauce (1 tablespoon): Contributes savory depth and a classic steakhouse vibe.
Shredded provolone or mozzarella cheese (1 cup): The melty “cheesesteak” topping that makes it irresistible.
Shredded cheddar cheese (1/2 cup): Gives a bold, sharp flavor pop that pairs beautifully with the mild cheeses.
Large eggs (3): Binds everything together and gives the casserole a perfect set.
Chopped parsley (optional, for garnish): A fresh, bright touch for that finished flare.

How to Make Philly Cheesesteak Casserole

Step 1: Sauté the Vegetables

Begin by heating olive oil in a large skillet over medium heat. Toss in the diced green bell pepper and onion, stirring occasionally for 4 to 5 minutes until the veggies are softened and smelling amazing. Add the minced garlic and cook for another minute, just until fragrant.

Step 2: Brown the Beef or Steak

Increase the sizzle: add your ground beef or thinly sliced steak directly into the pan. Sprinkle with salt and black pepper, and cook, breaking up the meat (or stirring the steak slices), until perfectly browned. Drain off any extra grease so your Philly Cheesesteak Casserole isn’t too heavy.

Step 3: Create the Creamy Base

Turn the heat down to low, then stir in the softened cream cheese, sour cream, and Worcestershire sauce. Mix well until the cheeses melt and everything forms a silky, creamy sauce that will cradle the beef and veggies. This is what makes each bite so luscious!

Step 4: Add Eggs for Binding

Whisk the eggs in a small bowl, then gently pour them into the skillet mixture. Stir well, making sure the eggs are fully incorporated—this step ensures the casserole holds together beautifully once baked.

Step 5: Assemble and Bake

Grease your 9×9-inch or 8×8-inch baking dish. Pour in the creamy beef and veggie mixture, smoothing it out evenly. Sprinkle provolone (or mozzarella) and cheddar cheese all over the top for that irresistible golden crust. Bake at 350°F (175°C) for 25 to 30 minutes until set, bubbly, and deliciously golden.

Step 6: Finish and Serve

Let the casserole rest for a few minutes when it comes out of the oven. Sprinkle with chopped parsley for a burst of freshness before serving. That’s it—you’re ready to enjoy Philly Cheesesteak Casserole at its very best!

How to Serve Philly Cheesesteak Casserole

Garnishes

Keep it classic with a generous sprinkle of freshly chopped parsley for a pop of color. You can also top each portion with a little extra cheese or a scatter of pickled jalapeños if you want some zing. Feel free to finish with cracked black pepper for a bistro-style look.

Side Dishes

This casserole is filling enough to stand alone, but it plays wonderfully with sides. Go classic with a crisp green salad tossed in vinaigrette, or serve with steamed green beans or broccoli. For a heartier feel (if carbs are welcome), a slice of crusty bread or even oven-roasted potatoes round out the meal beautifully.

Creative Ways to Present

Try spooning the Philly Cheesesteak Casserole into hollowed-out bell peppers or small oven-safe ramekins for individual servings—the presentation is adorable! Or, turn leftovers into a sandwich filling or wrap for an instant lunch upgrade.

Make Ahead and Storage

Storing Leftovers

Let the casserole cool completely before covering and transferring to the fridge. It will stay fresh for up to 3 days—just reheat portions as needed for quick weekday meals. Easy, tasty leftovers are practically guaranteed!

Freezing

To freeze, wrap the cooled Philly Cheesesteak Casserole tightly in plastic wrap and foil, or use an airtight container. Freeze for up to 2 months. For best results, thaw overnight in the fridge before reheating so the texture stays creamy and delicious.

Reheating

Reheat individual servings in the microwave for 1 to 2 minutes, covered, until hot. For larger portions, cover with foil and warm in a 350°F oven for 10 to 15 minutes. You can add an extra sprinkle of cheese before reheating for an extra-melty finish!

FAQs

Can I use different cheeses in my Philly Cheesesteak Casserole?

Absolutely! While provolone, mozzarella, and cheddar are classic choices, feel free to use pepper jack for some heat, or swap in Swiss for a nuttier note—just choose cheeses that melt well for the best result.

Is this casserole keto or gluten-free?

Yes, this Philly Cheesesteak Casserole is naturally low-carb, gluten-free, and perfect for keto diets. Just be sure your Worcestershire sauce is gluten-free if you’re sensitive.

Can I make this ahead and bake it later?

Definitely! Assemble everything up to the baking step, cover tightly, and refrigerate up to 24 hours. When ready to serve, bake as directed (add a few extra minutes if cold from the fridge).

What’s the best cut of steak for Philly Cheesesteak Casserole?

Ribeye is the classic choice for a true Philly cheesesteak flavor, but sirloin or even leftover roast beef work beautifully. For convenience, ground beef gives great flavor and texture with a simple swap.

Can I add mushrooms or other veggies?

Of course! Mushrooms, roasted red peppers, or sautéed spinach make great additions. Just cook them before mixing into the casserole to avoid excess moisture.

Final Thoughts

If you love cozy, family-style comfort food with bold Philly flavors, you’re going to adore this Philly Cheesesteak Casserole. It’s an easy, irresistible way to bring everyone around the table—just bake, serve, and watch it disappear. Give it a try and enjoy the taste of Philly in casserole form!
