Drain excess grease
If you use regular ground beef and there's a lot of fat in the skillet, drain it before adding the cream cheese.
This keeps the casserole from becoming greasy.
Soften the cream cheese
Soft cream cheese blends much more easily.
If you forgot to take it out of the refrigerator, cut it into small pieces before adding it to the skillet.
Don't overcook the vegetables
You want the onions and peppers tender but not mushy.
They'll continue cooking while the casserole bakes.
Use freshly shredded cheese
If you have the time, shred your own cheese.
It often melts more smoothly than pre-shredded cheese.
Don't skip the resting time
Give the casserole a few minutes to cool before serving.
It will be easier to scoop and much less likely to fall apart on the plate.
Can You Make Philly Cheesesteak Casserole Ahead of Time?
Yes!
This is a great make-ahead dinner.
Prepare the beef and vegetable mixture, combine it with the cream cheese, and transfer everything to the casserole dish.
Add the cheese topping, cover, and refrigerate until you're ready to bake.
Because the casserole will be cold from the refrigerator, it may need additional baking time.
Make sure the center is heated through and the cheese is completely melted before serving.
How to Store Leftovers
Place leftover casserole in an airtight container and refrigerate.
For best quality, enjoy it within 3–4 days.
Reheat individual portions in the microwave or warm larger portions in the oven until heated through.
The leftovers make a wonderfully easy lunch the next day.
Can You Freeze Philly Cheesesteak Casserole?
Yes, although casseroles containing cream cheese can sometimes have a slightly different texture after freezing and thawing.
Allow the casserole to cool completely, then transfer portions to freezer-safe containers.
Thaw overnight in the refrigerator before reheating.
For the best texture, reheat gently in the oven.
