Tips for the Best Chicken Parmesan Casserole
- Use high-quality marinara sauce – A good sauce can make a big difference in flavor.
- Cook pasta al dente – Slightly undercooking the pasta prevents it from becoming mushy when baked.
- Use freshly grated cheese – Pre-shredded cheese contains anti-caking agents that can affect melting.
- Toast breadcrumbs first – For an extra crunchy topping, lightly toast the panko before adding it.
- Let it rest before serving – This allows the flavors to settle and prevents the cheese from being too runny.
