Ingredients You’ll Need

Here’s what you’ll need to build this cheesy masterpiece:

• Ground beef: A quicker and easier stand-in for sliced steak, still delivering that hearty flavor.
• Bell peppers: Go for a mix of green and red for color and sweetness.
• Onion: Adds depth and that classic Philly flavor. Yellow or sweet onions work great.
• Garlic: A few cloves minced really boost the flavor—don’t skip it.
• Cream cheese: Helps create a rich, creamy base that ties everything together.
• Worcestershire sauce: Adds a savory umami punch that mimics the flavor of grilled steak.
• Eggs: Used to help bind the casserole so it holds together nicely when sliced.
• Shredded provolone or mozzarella cheese: Melts beautifully for that gooey, cheesy topping.
• Seasonings: Salt, black pepper, and a pinch of Italian seasoning for added flair.
• Optional: Mushrooms: If you’re a mushroom fan, slice some in—they go wonderfully with the beef and cheese.

Variations

Feel like putting your own twist on it? Try one of these easy swaps:

• Low-carb version: Skip the bread base altogether and add extra veggies.
• Use thin-sliced steak: Swap the ground beef for thinly sliced ribeye if you want a more authentic feel.
• Spicy style: Add jalapeños or a dash of hot sauce to give it a kick.
• Cheese options: Try pepper jack for spice, or a sharp white cheddar for bolder flavor.
• Add a crust: Pour the beef mixture over toasted hoagie buns or a layer of crescent roll dough for a sandwich-style casserole.

How to Make Easy Philly Cheese Steak Casserole

Step 1: Prep the Veggies and Beef

In a large skillet over medium-high heat, cook the ground beef until it’s browned and cooked through. Drain any excess fat, then add diced bell peppers, onion, and garlic. Cook until the veggies are softened and fragrant.

Step 2: Mix in the Creamy Base

Lower the heat and stir in the cream cheese and Worcestershire sauce until smooth and creamy. Let it simmer for a minute, then season with salt, pepper, and Italian seasoning to taste.

Step 3: Assemble the Casserole

In a large mixing bowl, beat the eggs and stir in half of the shredded cheese. Add the beef and veggie mixture, and combine everything well.

Step 4: Bake

Pour the mixture into a greased casserole dish and top with the remaining cheese. Bake at 375°F (190°C) for 25–30 minutes, or until the cheese is bubbly and slightly golden on top.

Step 5: Cool Slightly and Serve

Let it sit for 5 minutes to set, then slice and serve warm.

Pro Tips for Making the Recipe

• Use lean ground beef: You’ll get all the flavor without an overly greasy casserole.
• Soften the cream cheese first: This helps it melt more easily into the beef mixture.
• Don’t overbake: Pull it out when the cheese is just bubbly and golden to keep everything tender and juicy.
• Let it rest: Giving the casserole a few minutes to cool makes it easier to cut and helps the flavors meld together.

How to Serve

This casserole is incredibly versatile, and you can serve it up in a variety of delicious ways:

On Its Own

Make Ahead and Storage

Storing Leftovers

Store cooled leftovers in an airtight container in the fridge for up to 4 days. It reheats beautifully.

Can I make this casserole ahead of time?
Yes, you can prepare the casserole up to a day in advance. Just assemble it, cover, and refrigerate. Pop it in the oven when you’re ready to bake.

Is this casserole keto-friendly?
It can be! Just double-check the ingredients—especially your Worcestershire sauce and cheese—to keep carbs low. Avoid bread or crust-based variations.

You can swap it for sour cream or a dollop of Greek yogurt if you want a tangier, lighter texture. Just note it won’t be quite as rich and creamy.
