Why You’ll Love This Philly Cheesesteak Casserole

This casserole is pure comfort on a plate. You get all the flavors of a Philly cheesesteak without the need to stand at the stove grilling sandwiches. It’s baked all in one dish, making cleanup a breeze. Plus, the rich blend of seasoned beef, sweet bell peppers, onions, and gooey cheese hits all the right savory notes. It’s great for family dinners, parties, or bringing to a potluck.

What Kind of Beef Should I Use?

For this casserole, ground beef works beautifully because it cooks quickly and blends evenly with the cheese and vegetables. However, if you’re going for authenticity, shaved ribeye steak gives that classic Philly texture and taste. You can often find shaved steak in the meat section of most grocery stores. Either option delivers savory, beefy flavor—so go with what you love.

Ingredients for the Philly Cheesesteak Casserole

This dish is made with everyday ingredients that come together in a big way. You’ll love how each element enhances the next, from the tender beef to the creamy cheese.

Salt and pepper
Italian seasoning
Olive oil
Eggs

The ground beef provides a rich, hearty base. Green bell pepper adds crunch and freshness, while yellow onion brings that essential sweetness. A touch of garlic rounds out the aromatics. Cream cheese and provolone melt into a smooth, cheesy sauce, and the eggs help bind the mixture together for a firm but creamy texture. Italian seasoning, salt, and pepper give it all the flavor punch it needs.

How To Make the Philly Cheesesteak Casserole

Step 1: Cook the Beef Mixture

Start by heating olive oil in a large skillet over medium-high heat. Add the ground beef and cook until browned, breaking it up with a spatula. Drain excess grease if needed.

Step 2: Sauté the Veggies

Add chopped green bell peppers and sliced onions to the skillet with the beef. Cook until the vegetables are soft, about 5-6 minutes. Stir in minced garlic and cook for another minute.

Step 3: Make It Creamy

Reduce the heat and add the cream cheese. Stir until it’s fully melted and coats the beef and veggies in a creamy mixture.

Step 4: Add the Eggs

Crack the eggs into a small bowl and beat them lightly. Pour the eggs into the skillet and stir to combine. This will help hold everything together when baked.

Step 5: Assemble and Bake

Preheat your oven to 375°F. Pour the mixture into a greased 9×13 baking dish. Top with sliced provolone cheese. Bake uncovered for 20-25 minutes, or until the cheese is golden and bubbly.

Serving and Storing Your Casserole

This Philly Cheesesteak Casserole feeds about 6 to 8 people, depending on portion sizes. It’s perfect served straight from the oven alongside a fresh green salad or even crispy French fries. If you’re going low-carb, a simple cucumber tomato salad is a fantastic pairing.

To store leftovers, let the casserole cool completely. Store individual portions in airtight containers in the refrigerator for up to 4 days. You can also freeze it for up to 2 months—just thaw overnight in the fridge and reheat in the oven or microwave until hot.

What to Serve With Philly Cheesesteak Casserole?

Garlic Bread

You can never go wrong with warm, buttery garlic bread to soak up all the cheesy goodness.

Roasted Broccoli

Lightly seasoned broccoli roasted until crisp-tender is the perfect healthy side to balance the dish.

Crispy Tater Tots

Give it a diner-style vibe with a handful of crispy tots on the side.

Sweet Potato Fries

For a touch of sweetness, try oven-baked sweet potato fries. They’re delicious dipped into any leftover cheese sauce.

Simple Caesar Salad

The cool, creamy dressing and crunchy croutons work beautifully with the richness of the casserole.

Dill Pickle Spears

Sounds strange, but the acidity of a dill pickle cuts through the creaminess in a really satisfying way.

Corn on the Cob

Grilled or steamed corn brings a sweet, buttery addition to your plate.

Pickled Red Onions

If you like a tangy bite, quick-pickled red onions offer a pop of color and flavor.
