This is my go-to chicken parmesan casserole recipe, and it never lets me down.

Classic chicken parmesan is delicious but genuinely involved, breading, frying, then baking, with a fair amount of mess along the way. This casserole strips out the breading step entirely and layers everything together instead, keeping all the flavor with a fraction of the effort.

This has become my go-to on nights I want that chicken parmesan craving satisfied without committing to a full breading and frying operation. One dish, minimal cleanup, genuinely great flavor.

Low carb friendly: easy to serve without pasta if you prefer.

Why This Works

Searing the chicken briefly before layering it into the casserole is what gives it real color and flavor instead of ending up pale and boiled-tasting under the sauce. That quick sear builds a bit of browning on the outside that carries through even after baking under the marinara and cheese.

Step-by-Step

Season the chicken breasts with salt, pepper, garlic powder, and Italian seasoning. Sear in a hot skillet with olive oil for about 3 minutes per side, just until lightly browned, they’ll finish cooking in the oven.

Chicken breasts searing in a skillet — A quick sear builds color and flavor before the chicken goes in the oven.

Spread a thin layer of marinara sauce in the bottom of a baking dish. Arrange the seared chicken breasts in a single layer over the sauce.

Pour the remaining marinara over the chicken, then top with shredded mozzarella and a sprinkle of grated parmesan. Cover the dish with foil.

Chicken layered with marinara and cheese in a baking dish — Layer the sauce, chicken, more sauce, then cheese.

Bake at 375 degrees for 25 minutes covered, then remove the foil and bake for another 10 minutes, until the chicken is cooked through and the cheese is golden and bubbling. Let it rest for 5 minutes before serving.

Top with fresh basil and serve over pasta, or on its own for a lower-carb option.

Tips

Let the casserole rest before slicing or serving, this helps everything set.
Use a good-quality marinara, it’s a major flavor component here.

Variations
