 Q & A

Q: Can I use steak instead of ground beef?

Yes! Use thin-sliced ribeye or sirloin. Cook quickly to avoid toughness.

Q: Can I make it ahead?

Absolutely. Assemble, cover, refrigerate up to 24 hours, then bake.

Q: Can I freeze this casserole?

Yes. Freeze baked or unbaked for up to 2 months.

Q: What cheese works best?

Provolone is classic Philly style, but mozzarella + cheddar gives great melt and flavor.

Q: Is this spicy?

No—but you can add red pepper flakes or jalapeños.

Drain beef fat well and don’t overcook vegetables.
