Can I use fresh chicken instead of rotisserie?
Yes. Poach or bake 3 cups boneless, skinless chicken breasts until cooked through, then shred. This adds about 20–30 minutes to prep time.
How do I know when the cornbread topping is done?
Bake until the cornbread is golden brown on top and a toothpick inserted into the crust comes out clean, typically 25–30 minutes at 350°F.
Can I make this casserole ahead?
Yes. Assemble the casserole up to 24 hours ahead, cover, and refrigerate. Add 5–10 minutes to the bake time if baking from cold.
What size baking dish do I need?
A 9×13-inch baking dish is standard for this recipe. A slightly smaller dish will create a thicker casserole; a larger one will be shallower.
Can I reduce the sodium in this recipe?
Use low-sodium cream soups and broth, and taste before adding the full salt amount. Fresh herbs like thyme or parsley add flavor without salt.
