For Philly Cheese Steak Casserole

Ground Beef – I use lean ground beef for a tender, juicy base. You can substitute with ground turkey or chicken for a lighter version.

Bell Peppers – These add a sweet, fresh crunch. You can use any color, but red or green are common choices.

Yellow Onion – Adds savory depth of flavor. You can swap with a white onion for a slightly sharper taste.

Garlic – For that aromatic, flavorful punch.

Seasoned Salt – A key seasoning to bring everything together. Lawry’s or Morton’s work well, but feel free to use any brand you prefer.

Provolone Cheese – This cheese melts beautifully and adds that creamy, tangy flavor you expect from a Philly cheese steak.

Eggs – Help bind everything together and create a satisfying, custardy texture.

Heavy Cream – Adds richness to the casserole and helps the egg mixture come together smoothly.

Hot Sauce – Adds a hint of spice to balance the richness, but adjust to taste.

Worcestershire Sauce – Provides a savory umami boost to the dish.

Can I prepare the casserole ahead of time?
Yes, you can absolutely assemble the casserole ahead of time! Simply prepare everything up to the baking step, cover, and refrigerate it for up to 24 hours. When you’re ready, just pop it in the oven!
What if I don’t have ground beef?
No problem! You can easily swap the ground beef for thinly sliced ribeye steak or any other cut of beef you prefer. Ground turkey or chicken will also work for a leaner alternative.
Can I freeze leftovers?
Yes, leftovers can be frozen! Let the casserole cool completely, then store in an airtight container for up to 3 months. When you’re ready to eat, thaw in the fridge overnight and reheat in the oven.
How can I make it spicier?
If you love a little heat, feel free to add more hot sauce or even a pinch of red pepper flakes into the beef mixture. You can easily customize it to your taste!
What if I don’t have Provolone cheese?
If you’re out of Provolone, don’t worry! Mozzarella or cheddar cheese make great substitutes. Provolone gives a nice melt, but either option will still create a deliciously cheesy casserole.
