How to Make the Best Philly Cheesesteak Casserole

Philly Cheesesteak Casserole is my weeknight golden ticket. When everyone is hungry and I want something cozy, cheesy, and hearty, this is the dish I turn to. It tastes like a hot sandwich in bubbly, creamy casserole form, and it always gets cheers at the table. Think tender steak, peppers, onions, and melty provolone wrapped around pasta in a creamy sauce. You get all the good stuff with way less mess. If you have 45 minutes and a baking dish, dinner is handled.

Ingredients Overview

• 1 pound thinly sliced steak, like shaved ribeye or sirloin
• 2 tablespoons olive oil
• 1 large onion, thinly sliced
• 1 green bell pepper and 1 red bell pepper, thinly sliced
• 8 ounces mushrooms, sliced (optional but tasty)
• 2 cloves garlic, minced
• 8 ounces dried pasta, like penne or rotini
• 4 ounces cream cheese, softened
• 1 cup beef broth
• 1 cup shredded mozzarella
• 6 to 8 slices provolone cheese
• 1 teaspoon Worcestershire sauce
• 1 teaspoon Italian seasoning
• Salt and black pepper to taste

I prefer steak shaved thin because it cooks fast and stays tender. Provolone brings that signature cheesesteak flavor, while a little mozzarella gives extra stretch. The cream cheese and broth make a simple sauce that clings to the pasta and steak without turning heavy. Keep the veggies sliced thin so they soften quickly without losing bite.

Optional Ingredients and Flavor Boosters

If you want to take it up a notch, add a splash of hot sauce for warmth or a spoon of Dijon for tang. A handful of pickled peppers is fantastic if you love that deli-style zip. Fresh parsley or chives brighten everything at the end. And if onions are your thing, caramelize them a little longer for a deeper, sweeter flavor.

Love that rich onion vibe in casseroles? You might also enjoy this comforting twist: French Onion Chicken Orzo Casserole. It pairs perfectly with cool evenings and comes together with pantry basics.

Ingredient Substitutions (Budget, Dietary, Allergy-Friendly)

Steak can be pricey, so swap in ground beef or thinly sliced deli roast beef if needed. You can also use chicken or ground turkey. If you are dairy sensitive, try lactose-free cream cheese and a dairy-free provolone-style cheese. For gluten-free, use your favorite gluten-free pasta and confirm your broth is gluten-free. If mushrooms are not your thing, skip them and add more peppers.

Craving a lighter bite? A low-carb version skips the pasta and doubles the vegetables. I talk more about this in the dietary section below, but it is a great option when you want comfort food without the starch.

Step-by-Step Instructions

Prep the steak and veg

• Preheat oven to 375°F. Grease a 9×13 baking dish.
• Cook pasta in salted water until just shy of al dente. Drain.
• Heat oil in a large skillet over medium-high. Sear steak in two batches for 1 to 2 minutes per side. Season with salt and pepper. Set aside.
• In the same pan, cook onions and peppers with a pinch of salt until softened, about 5 to 7 minutes. Add mushrooms and cook 3 minutes more. Stir in garlic for 30 seconds.

Build the casserole

• Reduce heat to low. Stir in cream cheese, beef broth, Worcestershire, and Italian seasoning. Let it melt into a creamy sauce. Taste and adjust salt and pepper.
• Add pasta, steak, and half the mozzarella. Toss to coat. Transfer to the baking dish.

Bake and finish

• Top with remaining mozzarella and lay provolone slices across the top.
• Bake for 18 to 22 minutes until bubbling at the edges.
• Broil for 1 to 2 minutes to get those golden, melty cheese spots. Rest 5 minutes before serving.

This is where the magic happens. The sauce thickens, the pasta drinks in flavor, and the top turns into a blanket of cheesy goodness. It smells like a sandwich shop and a cozy kitchen had a very delicious baby.

Expert Tips for Best Results

Slice steak thin while it is still slightly chilled. It is easier to get those delicate strips and they cook more evenly. Avoid overcooking the steak in the pan because it will keep cooking in the oven. Let your cream cheese warm up at room temp for 15 minutes so it melts smoothly into the sauce.

If your sauce looks thin, simmer it for a minute before tossing with pasta. If it looks too thick, splash in a bit more broth. And do not skip the rest time after baking. That short pause helps everything set so you get clean scoops and not casserole chaos.

Time-Saving Shortcuts and Make-Ahead Options

Short on time? Buy pre-sliced peppers and onions and grab shaved steak from the butcher. Cook the pasta and chop your vegetables earlier in the day. You can assemble the casserole up to 24 hours ahead, cover, and refrigerate. Add 5 to 8 minutes to the bake time if it is going into the oven cold.

On extra busy nights, I keep another easy favorite in rotation. This hearty crockpot hamburger potato casserole gives you the same cozy vibes with a set-it-and-forget-it approach.

Variations of the Recipe

Switch up the cheese. Provolone is classic, but white American or pepper jack makes it fun and melty. Try different veggies too. Roasted red peppers, jalapeños, or even spinach work. Want it extra saucy? Stir in a splash of heavy cream with the cream cheese for a richer base.

No-pasta low-carb twist

Skip the noodles and use more peppers, onions, and mushrooms. Add chopped cauliflower for extra bulk. This gives you the flavor of Philly Cheesesteak Casserole without the carbs but keeps the comfort factor high.

Best Side Dishes to Pair With It

A crisp green salad with a tangy vinaigrette balances the richness. Garlic bread is a crowd-pleaser for scooping up saucy bits. For holiday dinners, I pair it with a classic like Campbells green bean casserole or go sweet with a seasonal twist like sweet potato casserole with marshmallows. Both play so nicely with the savory steak and cheese.

Storage and Reheating Instructions

Store leftovers in an airtight container up to 4 days. For the best texture, reheat in a 350°F oven for 12 to 15 minutes, covered with foil. You can microwave single portions in 60 to 90 second bursts, stirring between rounds. The cheese stays smoother if you add a spoonful of broth before reheating.

Freezing tip: Wrap tightly and freeze up to 2 months. Thaw in the fridge overnight, then reheat covered at 350°F until hot in the center.

Equipment You Need

You do not need fancy tools for this one. A large skillet, a pot for boiling pasta, a 9×13 baking dish, and a sharp knife get the job done. A broiler-safe baking dish helps you achieve that bubbly, browned top without switching pans. If your skillet is oven-safe, you can even build and bake in the same pan for fewer dishes.

How to Double or Triple the Recipe

Cooking for a crowd? Double the ingredients and use two baking dishes so the casserole heats evenly. When casseroles get too deep, they can turn soggy. Bake on the middle rack and rotate the dishes halfway. If you triple it, plan on three pans or one full sheet pan with high sides. Give yourself an extra 5 minutes in the oven and check for bubbling all the way through.

Dietary Adaptations

Gluten-free is straightforward with GF pasta and broth. Dairy-free can be done with plant-based cream cheese and a good melting vegan cheese. For low-carb, stick to the no-pasta version and load up on vegetables or use spaghetti squash strands as the base. It keeps all the steak-pepper-onion flavor you love and still satisfies.

Gluten-free notes

Undercook gluten-free pasta by a minute so it does not break down. Drain well and toss with a touch of oil before mixing into the sauce to keep it from sticking. This helps keep the texture pleasant after baking.

Troubleshooting Guide

If your casserole is watery, it usually means the peppers released extra moisture. Sauté them a touch longer next time and simmer the sauce one more minute. If it is too dry, add a little extra broth or a drizzle of olive oil before baking. Cheese not browning? Move the rack higher and broil briefly, keeping a close eye on it.

Steak turned tough? You likely overcooked it in the skillet. Aim for a quick sear and let the oven finish the job. Season as you go so every layer tastes great and you will never have a bland bite.

Cost Breakdown & Budget Tips

Prices vary by region, but here is a ballpark: steak 8 to 10 dollars, pasta 1 to 2 dollars, veggies 4 dollars, dairy and cheese 5 to 7 dollars, pantry items 1 to 2 dollars. That puts a big 6-person pan around 20 to 25 dollars, which is pretty good for a hearty dinner. Buy steak on sale and freeze it in thin slices. Use store-brand cheese and broth to trim the total without sacrificing flavor.

Batch-cook peppers and onions on the weekend so you can toss them into this and other weeknight dinners. It saves time and keeps your budget in check.

Calories and Macros and Key Nutritional Benefits

A generous serving of this Philly Cheesesteak Casserole lands around 520 to 600 calories depending on cheese and pasta choices. Protein sits around 30 to 35 grams, carbs about 40 to 50 grams, and fat roughly 22 to 28 grams. Veggies add vitamin C, fiber, and antioxidants. Steak brings iron and B12. You can lighten it up by using a bit less cheese or swapping half the pasta for mushrooms.

Common Questions

Q: Can I use leftover steak?
A: Yes. Slice it thin and add it in with the pasta so it warms gently without drying out.

Q: What if I only have block provolone?
A: Shred it and scatter over the top. It will melt beautifully and cover more evenly.

Q: How spicy can I make it?
A: Add red pepper flakes, jalapeños, or pepper jack. Start small and build until it hits your sweet spot.

Q: Can I skip the cream cheese?
A: You can. Use 1 cup heavy cream or 3/4 cup half and half instead. The sauce will be looser and silky.

Q: What is the best pasta shape?
A: Short, ridged pasta like penne or rotini grabs sauce and holds up to baking.
