Chicken Parmesan Casserole: The Cozy Weeknight Hero
There’s a reason chicken parmesan has stood the test of time. Crispy breaded chicken, rich marinara sauce, gooey cheese — it’s comfort food at its best. The only problem? Traditional chicken parm is a production: dredging, frying, layering, and usually more dishes than anyone wants to tackle on a Tuesday night.
That’s where this Chicken Parmesan Casserole swoops in. It takes everything people love about the original and re-imagines it as a one-pan, family-friendly bake. It’s hearty, cheesy, and yes — it still has that satisfying crunch thanks to a clever shortcut (spoiler: it’s croutons).
This casserole has quickly become one of my go-to dinners when I need something that feels indulgent but doesn’t demand hours in the kitchen. It’s also one of those recipes you can put in front of a picky crowd and know you’ll get clean plates.
Why This Recipe Works
- Less mess, same flavor. No frying means less cleanup and no oil splatter.
- Croutons = breading. Instead of breading chicken, crunchy croutons do the work.
- Feeds a crowd. Perfect for potlucks, family dinners, or when you want leftovers.
- Customizable. Works with chicken, turkey, or even plant-based proteins.
