Can I make this casserole ahead of time?
Yes. Assemble the casserole, cover with foil, and refrigerate up to 24 hours. Bake from cold, adding 5–10 minutes to the cooking time.
What can I use instead of rotisserie chicken?
Cooked shredded chicken breast, canned chicken, or leftover roasted chicken work well. Use about 3 cups total.
Can I substitute the cheese?
Yes. Mozzarella, Swiss, or a blend work. Avoid soft cheeses that won't melt properly.
How do I know when the casserole is done?
The crescent rolls should be golden brown and the cheese sauce should be bubbling around the edges, typically 25–30 minutes at 375°F.
Can I freeze this casserole?
Freeze unbaked for up to 3 months. Thaw overnight in the refrigerator and bake as directed, adding a few extra minutes if needed.
