👩🍳 Step-by-Step Instructions
- Prep the Steak and Oven
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
Slice your partially frozen steak as thinly as possible against the grain. Season lightly with salt and pepper. - Sauté the Veggies
Heat the olive oil and 1 tbsp of butter in a large skillet over medium-high heat.
Add the sliced onions and green peppers. Sauté for 6–8 minutes until they are soft and starting to caramelize.

Add the minced garlic and cook for 1 more minute until fragrant. Remove the vegetables from the skillet and set them aside on a plate. - Sear the Steak
In the same skillet (don’t wipe it out; those browned bits are flavor!), add a little more oil or butter if needed.
Increase the heat to high. Add the thinly sliced steak in a single layer (work in batches if necessary so you don’t overcrowd the pan).
Sear for just 1–2 minutes per side until browned but still slightly pink in the middle. Do not overcook, or the steak will become tough. - Build the Casserole
Return the sautéed onions and peppers to the skillet with the steak.
Pour in the beef broth and Worcestershire sauce. Stir well, scraping up any browned bits from the bottom of the pan. Let it simmer for 1 minute, then remove from heat.
Transfer the entire steak and vegetable mixture into your prepared 9×13-inch baking dish, spreading it into an even layer. - Add the Bread and Cheese
Scatter the cubed hoagie rolls evenly over the top of the meat mixture.
Sprinkle the shredded Provolone and Mozzarella generously over the bread. (If using Cheez Whiz or American cheese, dollop it in small spoonfuls over the meat before adding the bread and shredded cheese).

Cheese - Bake to Golden Perfection
Bake uncovered for 20 to 25 minutes, or until the cheese is melted, bubbly, and the bread cubes on the edges are golden and crispy.
Optional: Broil for the last 2–3 minutes to get extra browning on the cheese (watch it closely so it doesn’t burn!). - Rest and Serve
Let the casserole rest for 5 to 10 minutes before serving. This allows the savory juices to settle and the cheese to set slightly, making it easier to scoop.
💡 Pro Tips for Perfection
The Freezer Trick: As mentioned, 30 minutes in the freezer is the ultimate hack for slicing steak at home. It makes cutting against the grain effortless.
Don’t Skip the Rest: Letting the casserole rest before digging in prevents it from being a soupy, sliding mess on the plate.
Stale Bread is Your Friend: If your hoagie rolls are fresh, toast the cubes in the oven for 5 minutes before adding them to the casserole. This ensures they stay pleasantly chewy-crisp rather than soggy.

How to Make It
Mushroom Lover’s
Add 8 oz of sliced cremini or button mushrooms to the skillet when sautéing the onions and peppers.
Spicy Cheesesteak
Swap the green bell pepper for a diced jalapeño, and add a pinch of red pepper flakes to the meat mixture.
Low-Carb / Keto
Omit the bread entirely. Increase the steak and veggies, and top with an extra layer of cheese. Bake as directed.
Ground Beef Shortcut
Short on time or budget? Substitute the sliced steak with 1.5 lbs of lean ground beef. Brown it with the onions and peppers, drain the fat, and proceed with the recipe.
🧊 Storage & Make-Ahead Instructions
Fridge
Store leftovers in an airtight container in the refrigerator for up to 3–4 days.
Reheat: Warm individual portions in the microwave, or cover the whole dish with foil and bake at 350°F (175°C) for 15–20 minutes until heated through.
Freezer
To Freeze (Unbaked): Assemble the casserole completely (meat, veggies, bread, and cheese). Wrap the dish tightly in plastic wrap, then a layer of heavy-duty aluminum foil. Freeze for up to 3 months.
To Bake from Frozen: Thaw overnight in the refrigerator. Bake at 375°F (190°C) for 35–45 minutes, removing the foil for the last 10 minutes to crisp the top.
Make-Ahead Prep
The Day Before: You can slice the steak, chop the vegetables, and cube the bread. Store them in separate airtight containers in the fridge. When ready to cook, simply sauté and assemble!
❓ FAQs: Your Questions, Answered
Q: Can I use Cheez Whiz like they do in Philadelphia?
A: Absolutely! If you want the most authentic Philly experience, spread a thin layer of warmed Cheez Whiz or melted American cheese over the meat mixture before adding the bread and Provolone. It adds an incredible, nostalgic creaminess.
Q: My casserole turned out a bit watery. What happened?
A: This usually happens if the steak released too much liquid or if the vegetables weren’t sautéed long enough to evaporate their moisture. Make sure to sear the steak quickly on high heat and let the broth reduce slightly before assembling.

Q: What can I serve alongside this?
A: Since it’s a hearty, carb-and-protein-rich dish, it pairs beautifully with lighter sides. Try a crisp green salad with a tangy vinaigrette, garlic green beans, or classic crispy french fries or tater tots.
Q: Can I make this in a slow cooker?
A: Yes! Sauté the veggies and steak first, then transfer everything to the slow cooker. Cook on LOW for 3–4 hours. Add the bread and cheese during the last 30 minutes of cooking.
