Let’s be real for a second—if you’ve ever bitten into a Philly cheesesteak and thought, “I wish I could just eat this straight out of a baking dish with a fork,” then congratulations. You’ve officially found your people… and your new favorite dinner.
This Philly Cheesesteak Casserole Bake takes everything we love about the classic sandwich—savory beef, melty cheese, sweet sautéed peppers and onions—and turns it into one cozy, cheesy, fork-friendly meal. No hoagie rolls required… although I won’t judge if you grab one to soak up every last bite.
I first made this on a busy weeknight with leftover steak and a serious craving for comfort food. The result? An empty casserole dish and a family asking when I was making it again. It’s easy, satisfying, and the kind of dinner that instantly earns a permanent spot in your rotation.
What Exactly Is a Philly Cheesesteak Casserole?
If “cheesesteak casserole” sounds confusing at first, think of it this way:
It’s the soul of a Philly cheesesteak—just baked into a warm, bubbly casserole instead of stuffed into bread. Same flavors, same comfort… way less mess.
Inside this dish, you’ll find:
- Tender steak slices or ground beef (both work beautifully)
- Sweet bell peppers and onions, cooked until soft and slightly caramelized
- Cream cheese for a rich, creamy base (trust me on this one)
- Plenty of melty provolone or mozzarella
- Optional add-ins like mushrooms or banana peppers if you’re feeling adventurous
Honestly? It’s hard to go wrong here.

Here’s everything you’ll want to have on hand:
- 1 lb thinly sliced steak or ground beef
- 1 green bell pepper, sliced
- 1 red bell pepper, sliced
- 1 medium onion, sliced
- 4 oz cream cheese
- 1 teaspoon garlic powder
- 1 teaspoon salt
- ½ teaspoon black pepper

Step-by-Step: Let’s Make Some Cheesesteak Magic
1. Preheat the oven
Set your oven to 375°F (190°C) so it’s ready to go.
2. Cook the meat
Heat a large skillet over medium heat with a drizzle of olive oil. Add your steak or ground beef and cook until browned and just cooked through. Drain excess fat if needed.
Tip: If using steak, don’t overcook it—you want it juicy and tender.
3. Sauté the veggies
Push the meat to the side (or remove it briefly) and add the peppers and onions to the skillet. Sauté for about 7–10 minutes, until soft and lightly caramelized. Season with garlic powder, salt, pepper, and Worcestershire sauce.
At this point, your kitchen is going to smell amazing.
4. Make it creamy
Lower the heat and add the cream cheese. Stir until it melts into the meat and veggies, creating a rich, creamy mixture.
This is the moment where self-control is tested.
5. Assemble the casserole
Transfer everything into a greased 9×13-inch baking dish. Sprinkle the shredded cheese generously over the top—no holding back.
6. Bake until bubbly
Bake for 15–20 minutes, or until the cheese is melted, bubbly, and lightly golden around the edges.
Let it cool for a few minutes… or don’t. I won’t tell.
Serving Ideas & Fun Twists
This casserole is totally satisfying on its own, but if you want to round it out:
