35-Minute Philly Cheesesteak Casserole
This Philly cheesesteak casserole gives you all the meaty, cheesy satisfaction of the classic sandwich without the bread. Ground beef meets sautéed peppers and onions in a creamy, savory base, then gets blanketed with a layer of bubbly provolone until the edges turn golden.
It comes together in one skillet and about 35 minutes. That makes it a solid pick when you want a hot, hearty dinner and don’t feel like juggling a lot of pans.
Why This Casserole Works
The filling keeps a loose, almost saucy texture from cream cheese and beef broth, so every bite stays moist. You get the same combo of tender meat, sweet peppers, and mild onion you’d expect from a steak sandwich, but in a form that feeds a family straight from the baking dish.
Provolone melts into a stretchy, lightly browned top that pulls apart with a fork. Cutting the short resting time lets the cheese set just enough so the portions hold together without turning stiff.
Ingredients
- 1 lb ground beef (80/20): higher fat keeps the filling juicy
- 1 medium onion, diced: yellow or white both work
- 1 green bell pepper, diced: swap in a red bell pepper for a sweeter note
- 2 garlic cloves, minced
- 2 tbsp olive oil
- 1/4 cup low-sodium beef broth: adds moisture and deepens the beefy flavor
- 2 tbsp Worcestershire sauce: brings the tangy, savory depth you taste in a good cheesesteak
- 4 oz cream cheese, softened: cut into small cubes so it melts quickly
- 6 oz sliced provolone: enough to cover the top in a single, even layer
- Kosher salt and black pepper: adjust to your taste
Variations / Substitutions
- Ground turkey: use it for a leaner casserole; you may want an extra splash of broth to prevent drying out.
- Mushrooms: add 8 oz sliced cremini or white mushrooms and sauté them with the peppers and onions for a more traditional cheesesteak feel.
- Different cheese: swap the provolone for sliced mozzarella or white American cheese if you prefer a milder melt.
- A little heat: stir a pinch of red pepper flakes into the beef mixture or serve with pickled jalapeños.
- Low-carb option: this recipe is already low in carbs as written and works well with a green salad on the side.

How to Make 35-Minute Philly Cheesesteak Casserole
Step 1: Brown the Ground Beef
Set a large oven-safe skillet over medium-high heat and add the 1 lb ground beef. Season with a pinch of salt and break the meat apart with a spoon. Cook until no pink remains and the edges begin to crisp, about 6 to 8 minutes.
The beef should be crumbly and fully browned, not steaming. Spoon off any excess fat so the finished dish doesn’t turn greasy, then transfer the meat to a plate.
Step 2: Sauté the Peppers and Onions
Return the skillet to medium heat and pour in the 2 tbsp olive oil. Toss in the diced onion and green bell pepper. Cook, stirring a few times, until the onion turns translucent and the peppers soften but still have a little bite, about 5 to 7 minutes.
Add the minced garlic and cook for 1 minute more, just until it smells fragrant. You want the vegetables tender and glossy, not mushy.
Step 3: Build the Creamy Filling
Reduce the heat to low and return the browned beef to the skillet. Pour in the 1/4 cup beef broth and 2 tbsp Worcestershire sauce, then scatter the small cubes of softened cream cheese over the meat. Stir continuously for 2 to 3 minutes until the cream cheese melts into a smooth, pale brown sauce that coats every piece of beef and pepper.
Taste the filling and add a few grinds of black pepper and a light pinch of salt if needed. The mixture should look creamy and loose, not pasty.
Step 4: Top and Bake the Casserole
Preheat your oven to 375°F (190°C). Scrape the hot filling into a greased 9×9-inch baking dish and spread it into an even layer. Arrange the provolone slices across the top so they overlap slightly and reach the edges.
Bake on the center rack for 20 to 25 minutes, until the cheese bubbles heavily and the outer rim turns a deep golden brown. Lift the pan out and let the casserole rest for 5 minutes before scooping onto plates. The cheese will settle slightly and cut cleanly into spoonfuls.
Tips for the Best Philly Cheesesteak Casserole
- Keep an eye on the cheese during the last few minutes of baking. If your oven runs hot, it can shift from golden to tough and rubbery fast.
- A heavy, oven-safe skillet lets you move straight from the stovetop into the oven and saves a dish to wash. If your skillet is not oven-safe, just transfer the filling to a casserole dish as written.
- For the creamiest results, take the cream cheese out of the fridge about 30 minutes before you start cooking. Cold cream cheese takes longer to melt and can leave tiny lumps.
Bake times by dish size:
| Dish size | Bake time at 375°F (190°C) |
|---|---|
| 8×8-inch | 22 to 25 mins |
| 9×9-inch | 20 to 25 mins |
| 9×13-inch | 15 to 18 mins |
Storing Leftovers
- Refrigerate: Let the casserole cool completely, then cover and store in the fridge for up to 4 days.
- Reheating: Warm individual portions in the microwave until heated through, or place the whole dish back in a 350°F (175°C) oven for about 10 to 12 minutes, loosely covered so the cheese stays soft.
What to Serve with Philly Cheesesteak Casserole
A tangy green salad with a sharp vinaigrette cuts through the richness of the cheese and beef. Garlic bread or buttered egg noodles work well if you want something on the side to catch every last bit of the creamy filling. For a lighter option, roasted broccoli or steamed green beans add color and crunch without much effort.
Frequently Asked Questions
Can I add pasta to this casserole?
Yes. Stir in 2 cups of cooked short pasta like ziti or rotini before topping with the cheese. You may need a splash more broth to keep the mixture from drying out.
Can I assemble it ahead of time?
You can build the filling, spread it in the dish, and refrigerate it covered for up to 24 hours. Add the provolone right before baking, and plan for an extra 10 minutes in the oven if you start from cold.
Will other cheeses melt as well as provolone?
Mozzarella and white American cheese both melt into a smooth, creamy topping. Sharp provolone brings a little more tang, while mild provolone or mozzarella keeps things subtle.
Can I freeze this casserole?
Freeze the assembled, unbaked casserole without the cheese layer. Wrap tightly and freeze for up to 2 months. Thaw overnight in the fridge, top with the provolone, and bake as directed, adding about 10 minutes.
Ingredients
Method
- Brown the ground beef in a large skillet over medium-high heat with a pinch of salt until fully cooked, about 6 to 8 minutes. Drain excess fat and set aside.
- Heat the olive oil in the same skillet over medium heat. Add the onion and bell pepper, cooking until softened, 5 to 7 minutes. Stir in the garlic and cook 1 minute.
- Return the beef to the skillet over low heat. Add the beef broth, Worcestershire sauce, and cream cheese, stirring until the cream cheese melts into a smooth sauce. Season with black pepper and a light pinch of salt.
- Preheat the oven to 375°F (190°C). Transfer the filling to a greased 9×9-inch baking dish. Lay provolone slices over the top and bake until the cheese is bubbly and golden at the edges, 20 to 25 minutes. Let it rest 5 minutes before serving.
