Looking for a comforting, hearty dish that combines all the flavors of a classic Philly cheesesteak but in a convenient casserole format? This Classic Philly Cheesesteak Casserole is your answer. It's perfect for family dinners or casual get-togethers, delivering savory goodness in every bite.
Ribeye steak is the star here, providing a tender, juicy base. You’ll want it thinly sliced for even cooking. Olive oil adds a layer of richness and helps in browning. Onion, green bell pepper, and red bell pepper bring sweetness and a bit of crunch, essential for that authentic cheesesteak taste. Mushrooms add an earthy depth, soaking up the flavors from the beef and veggies. Provolone cheese offers a mild, creamy melt, while mozzarella cheese provides its signature gooeyness. Heavy cream and beef broth ensure the casserole stays moist and flavorful. Finally, cubed bread acts as a hearty filler, absorbing all those delicious juices.
This casserole pairs beautifully with a crisp, fresh salad to balance the richness. A simple vinaigrette or Caesar salad works wonders. For a more indulgent meal, serve alongside some roasted potatoes or a warm, crusty loaf of bread to mop up the delicious juices.
First things first, preheat your oven to 350°F (175°C) and grease a 9x13 inch baking dish. This will ensure nothing sticks and cleanup is a breeze. Next, heat up some olive oil in a large skillet over medium-high heat. Add the thinly sliced steak, cooking it for about 4-5 minutes until it’s nicely browned. Then, remove the steak from the skillet and set it aside for now.
In the same skillet, toss in your sliced onions, bell peppers, and mushrooms. Sauté them for 5-7 minutes until they soften and their flavors meld together – this step is crucial for that authentic cheesesteak taste. Once they’re ready, grab a large bowl and combine the cooked steak, sautéed veggies, shredded provolone, shredded mozzarella, heavy cream, and beef broth. Stir in the bread cubes, making sure everything is well coated and seasoned with salt and pepper.
Now, transfer this mixture into your prepared baking dish, spreading it out evenly. Pop it into the preheated oven and bake for 25-30 minutes. You’ll know it’s done when the cheese is bubbly and golden brown on top. Allow the casserole to cool for about 5 minutes before serving – this helps the flavors settle and makes it easier to slice.
