Philly Cheesesteak Casserole That Brings Big Comfort to the Dinner Table

If you love the bold, savory flavor of a classic Philly cheesesteak but want something easier to make for a family dinner, this Philly Cheesesteak Casserole is the answer. It turns those familiar sandwich flavors into a hearty baked pasta dish with ground beef, Italian sausage, tender peppers and onions, and plenty of melty provolone and mozzarella. The original recipe uses ground beef, Italian sausage, sliced onion, green bell pepper, cooked pasta, beef broth, and a generous layer of cheese, all baked together until hot and bubbly. 

This is exactly the kind of weeknight dinner that feels satisfying and comforting without being complicated. The recipe on the source page is designed for 6 to 8 servings and comes together in about 50 minutes total, which makes it practical for family meals, casual gatherings, or meal prep for the next day. 

Why I Love This Recipe

I love this casserole because it captures the spirit of a cheesesteak in a format that is easier to make and easier to serve. Instead of fussing with rolls and sandwich assembly, everything bakes together in one dish, so you get the same savory payoff with a lot less effort. The mix of beef and Italian sausage gives the casserole a richer flavor than ground beef alone, while the peppers and onions bring that classic cheesesteak feel. 

It also fits beautifully into a comfort-food dinner rotation. If you enjoy meals like This Dorito Casserole Is My Favorite Weeknight Dinner Shortcut, This Mexican Chicken and Rice Casserole Is My Favorite One-Pan Dinner That’s Always a Hit, or This Instant Pot Lasagna Is My Favorite Way to Make Comfort Food Fast, this recipe belongs in that same crowd-pleasing category.

Ingredients

Based on the source recipe, you’ll need: 

• 1 pound ground beef
• 1 pound Italian sausage
• 1 large onion, sliced
• 1 large green bell pepper, sliced
• 3 cups cooked pasta
• 2 cups shredded provolone cheese
• 1 cup shredded mozzarella cheese
• 1 cup beef broth
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• Salt and pepper, to taste
• 1 tablespoon olive oil

Swaps and Notes

The original recipe notes that you can use any short pasta you like, with penne or rotini working especially well. It also suggests adding sautéed mushrooms or sliced jalapeños for extra flavor, which is a great way to lean into either the classic steakhouse vibe or a spicier variation. 

Provolone is the cheese that most strongly ties this casserole back to cheesesteak flavor, while mozzarella adds extra melt and stretch. You can keep that combination as written, or add a bit of cheddar if you want an even sharper finish. That last suggestion is my own variation, but the source specifically confirms that swapping cheeses is flexible. 

How to Make Philly Cheesesteak Casserole

Here’s the method adapted from the source recipe: 

1. Preheat your oven to 350°F.
2. Heat the olive oil in a large skillet over medium heat.
3. Add the sliced onion and green bell pepper and cook until softened, about 5 minutes.
4. Add the ground beef and Italian sausage, breaking the meat apart as it browns.
5. Drain excess fat if needed.
6. Stir in the garlic powder, onion powder, salt, and pepper.
7. In a large bowl, combine the cooked pasta with the meat mixture and beef broth.
8. Transfer everything to a greased 9×13-inch baking dish.
9. Top with the provolone and mozzarella.
10. Cover with foil and bake for 20 minutes.
11. Uncover and bake another 10 to 15 minutes, until the cheese is melted and bubbling.
12. Let it rest for a few minutes before serving.

Tips for Success

The source highlights two core techniques here: sautéing the vegetables first to bring out their sweetness and baking long enough for the cheese to turn gooey and lightly golden. It also notes that you should watch the casserole near the end so the cheese does not overbrown. 

I’d also recommend cooking your pasta just to al dente before mixing it into the casserole. That way it holds up well during baking and does not become too soft after absorbing some of the broth.

Serving Suggestions and Pairings

Because this casserole is rich and cheesy, it pairs well with something simple and fresh on the side, like a crisp salad or roasted vegetables. For a full comfort-food dinner lineup, it also sits nicely alongside Easy Cheesy Chicken Sliders with Marinara Garlic Butter for a game-day style spread or These Chicken Enchiladas Are My Go-To for Cozy Crowd-Pleasing Dinners if you are planning several family-friendly meals for the week.

Nutritional Information Per Serving

The original page does not provide calorie or macro information, so I cannot verify exact nutrition from the source. What is confirmed is the yield: this recipe serves 6 to 8 people. 

Storage and Leftover Tips

The source notes that leftovers keep well in the fridge and can be reheated easily for a quick lunch or dinner. It also says the casserole can be assembled up to the baking step and refrigerated for up to 24 hours before baking, which makes it especially useful for meal prep or entertaining.
