• 1 packet fajita seasoning (1.12 oz) – The spice blend that ties it all together with smoky, zesty flavor.

Cheesy Topping:

• 8 oz shredded Mexican blend cheese (about 2 cups) – Melts beautifully and finishes the casserole with a gooey, golden layer.

Popular Questions

Can I make this casserole ahead of time?

Yes. Assemble the casserole up to 24 hours in advance, refrigerate, and bake when ready.

Can I use long-grain rice instead of instant?
