How to Make Philly Cheesesteak Casserole Recipe
Step 1: Sear the Meat and Sauté the Vegetables
Start by preheating your oven to 375°F (190°C) and greasing a 9×13-inch casserole dish so nothing sticks during baking. Heat a large skillet over medium heat; if working with thinly sliced steak, drizzle in the olive oil. Brown the ground beef or steak until cooked through and caramelized—the browning is what imparts that irresistible savory depth. Once done, drain off any excess fat to keep the casserole from getting greasy. Next, toss in the chopped green and red bell peppers, sliced onions, and minced garlic. Sauté everything together until the veggies soften and become fragrant, usually about 5 to 6 minutes. Finish this step off with a splash of Worcestershire sauce and a generous pinch of salt and pepper to punch up the classic Philly flavor profile.
Step 2: Mix the Creamy Base
In a large mixing bowl, combine the softened cream cheese with the sour cream and Dijon mustard if you’re using it for that extra tang. Stir in the beaten eggs thoroughly until the blend is smooth and creamy. This mixture will give your casserole that dreamy, luscious creaminess that sets it apart from your typical beef bake.
Step 3: Combine Meat Mixture with Creamy Base
Now, gently fold the cooked beef and vegetable mixture into your creamy base. If you’re opting to add cooked pasta for a heartier meal, fold it in now as well. This step ensures every bite has that perfect balance of protein, veggies, and creamy goodness without any dryness.
Step 4: Assemble and Bake
Pour the combined mixture into your prepared casserole dish and spread it evenly. Generously sprinkle the shredded provolone or mozzarella cheese on top—this layer is critical for that golden, gooey crust that makes a Philly Cheesesteak Casserole Recipe so irresistible. Bake uncovered for about 20 to 25 minutes until the casserole is hot, bubbly, and the cheese has melted to a beautiful golden brown. Let it rest for 5 minutes before serving to let everything set and allow the flavors to marry.
How to Serve Philly Cheesesteak Casserole Recipe
Garnishes
For a fresh finish, sprinkle some chopped parsley on top just before serving. Not only does it add a vibrant touch of green, but it also brings a mild herbaceous brightness that perfectly balances the richness of the casserole.
Side Dishes
This casserole pairs beautifully with a crisp green salad dressed in a light vinaigrette to cut through the richness and keep the meal balanced. Roasted or steamed veggies like asparagus or broccoli are fantastic too, adding nutritional variety and crunch.
Creative Ways to Present
Want to elevate your presentation? Serve the casserole in individual ramekins for a personalized touch during dinner parties, or scoop portions into toasted hoagie rolls for a fun twist that echoes the classic Philly cheesesteak sandwich form.
Make Ahead and Storage
Storing Leftovers
Leftover Philly Cheesesteak Casserole Recipe keeps wonderfully in an airtight container in the refrigerator for up to three days. This makes it a great option for meal prepping or enjoying as a satisfying lunch the day after.
Freezing
If you want to freeze the casserole, allow it to cool completely before wrapping it tightly with foil or plastic wrap. It can be frozen for up to two months. Just be mindful that the texture of the peppers might soften slightly upon thawing, but the flavor will remain delicious.
Reheating
Reheat leftovers in the oven at 350°F for 15-20 minutes or until warmed through for the best texture and to revive that cheesy top layer. You can also microwave individual portions, but the oven method preserves the casserole’s integrity beautifully.
FAQs
Can I use other types of cheese besides provolone?
Absolutely! Mozzarella is a great substitute for its melting quality, and even a sharp cheddar or Monterey Jack can introduce a wonderful flavor dimension. Feel free to experiment with what you love.
Is it necessary to use steak, or can I stick with ground beef?
Ground beef works perfectly here and is often more economical and easier to cook. While steak adds that authentic Philly texture, the ground option still delivers incredible savory flavor to the casserole.
Can I make this casserole low-carb?
Yes! Simply omit the pasta, and the casserole remains rich, filling, and delicious with plenty of protein and veggies. This makes it a great option for low-carb or keto-friendly meal plans.
What type of pasta works best if I want to include it?
Penne, egg noodles, or small pasta shapes hold up well and catch the creamy sauce beautifully. Just be sure to cook the pasta al dente to prevent it from getting mushy during baking.
Can I prepare this casserole ahead of time and bake later?
Definitely. You can assemble the casserole in the dish, cover it tightly with foil, and refrigerate it up to 24 hours before baking. This makes for a stress-free meal solution when entertaining or managing busy days.
