🧄 Ingredients (Serves 6–8)
Lean ground beef (90/10)
1½ lbs
Leaner cuts work best — less grease
Bell peppers (any color)
2, sliced
Green for classic flavor, red/yellow for sweetness
Yellow onion
½ large, thinly sliced
Sweetness and aroma
Garlic, minced
1 clove
For depth
Seasoned salt (Lawry’s or Morton’s)
1 tsp
The signature Philly flavor
Provolone cheese
4 slices, torn or chopped
Melts beautifully — or use shredded
Large eggs
4
Binds the casserole together
Heavy cream
¼ cup
Adds richness and silkiness
Hot sauce (like Cholula or Frank’s)
1 tsp
Zesty kick — adjust to taste
Worcestershire sauce
1 tsp
Umami depth
Optional: Sliced mushrooms
1 cup
For extra savoriness
✅ Pro Tip: For a low-carb version, skip the crust — it’s already naturally bread-free!
🥣 Step-by-Step: How to Make Philly Cheesesteak Casserole
Step 1: Preheat & Prep
Preheat oven to 375°F (190°C)
Grease a 9×13-inch baking dish or 10-inch cast-iron skillet
Step 2: Cook the Filling
In a large skillet over medium heat, cook ground beef until browned
Drain excess fat
Add bell peppers, onion, and garlic
Cook 5–7 minutes until vegetables are soft and caramelized
Stir in seasoned salt and remove from heat
✅ Pro Tip: Don’t skip the caramelization — it adds sweetness and depth.
Step 3: Add the Cheese
Stir Provolone cheese into the hot beef mixture — let it melt and coat everything
Step 4: Make the Custard Base
In a bowl, whisk:
4 eggs
¼ cup heavy cream
1 tsp hot sauce
1 tsp Worcestershire sauce
Whisk until smooth and slightly frothy.
Step 5: Combine & Bake
Pour the egg mixture over the beef and cheese in the skillet (if oven-safe)
Or transfer everything to the greased baking dish
Stir gently to combine
Bake 35–40 minutes, until:
Center is set
Top is golden brown
Knife comes out clean
Step 6: Cool & Serve
Let rest 5–10 minutes — this helps it set for cleaner slices
Cut into squares and serve warm
✅ Serving ideas:
With a side of crusty bread (to soak up juices)
Over mashed potatoes (yes, really)
With a cold beer or Irn-Bru (a true Philly touch)
🧑🍳 Pro Tips for the Best Casserole Every Time

Keep it moist, not dry
Add mushrooms
For a restaurant-style depth
Top with extra cheese
Broil 2–3 mins at the end for a golden crust
Make ahead
Assemble, refrigerate, bake when ready
Also, this casserole reheats beautifully — microwave or oven.
🍴 Final Thoughts: Sometimes the Best Sandwich Isn’t on a Roll — It’s in a Dish

We love the mess.
But what if you could capture that flavor — without the paper wrap, the drips, or the 2 a.m. craving?
This Philly Cheesesteak Casserole proves that comfort food doesn’t need to be complicated.
So next time you’re craving something hearty, cheesy, and deeply satisfying…
Don’t reach for the roll.
Reach for the casserole dish.
Because sometimes, the difference between “just dinner” and “I need the recipe”…
Isn’t in the meat.
It’s in the custard.
And once you make this?
You’ll wonder how you ever waited so long.
