Keto Shredded Chicken Parmesan Casserole

Chicken Parmesan is one of those iconic comfort foods we all grew up loving—crispy chicken, rich tomato sauce, gooey cheese… what’s not to crave? But let’s be honest, the breading and pasta don’t exactly vibe with the keto lifestyle. That’s where this Keto Chicken Parmesan Casserole comes in.

We whipped this one up on a cozy weeknight when we were both seriously craving something indulgent, nostalgic, and hearty—without the carb crash. It quickly became a staple for us. It’s got everything we love about the classic dish: savory shredded chicken, layers of marinara, a golden bubbly cheese topping, and even a crispy parmesan “breadcrumb” crust that gives it that signature texture.

This casserole is one of our favorite keto dinner hacks. It’s simple enough to throw together on a weeknight, but satisfying enough to serve guests or keep in the fridge for leftovers. And trust us—the leftovers are just as dreamy.
