Can I use fresh chicken breast instead of frozen patties?
Yes. Pound boneless, skinless chicken breasts thin, bread them, and bake at 375°F for 15–18 minutes until golden before layering into the casserole.
How do I prevent the casserole from drying out?
Do not overbake. Cover with foil for the first 20 minutes at 375°F, then uncover to brown the cheese for 10–12 minutes until bubbly around the edges.
Can I make this ahead?
Yes. Assemble the casserole, cover tightly with plastic wrap, and refrigerate up to 24 hours. Add 5–10 minutes to baking time if baking from cold.
What if I don't have fresh mozzarella?
Shredded mozzarella works equally well. Use 8 oz and sprinkle it over the marinara layer before the final parmesan topping.
How many servings does this recipe make?
This casserole serves 4–6 people as a main dish, depending on portion size and sides.
