I sauté pan-seared chicken breasts in a deliciously soupy sauce, then cover the whole thing in glorious melted gruyere cheese. My skillet French onion chicken is a sensory delight and a fun take on a classic dish. The best part of this recipe is that it goes from the stovetop to the oven all in one pan, so there’s almost no clean-up afterwards.

One Simple Tip!
I highly recommend using a cast iron skillet for this easy French onion chicken recipe. It distributes heat evenly, which ensures the perfect juicy chicken breast. Plus it can go from the stove to the oven without a problem, making this an easy one pan chicken recipe. However, another oven-safe skillet works too.
If you don’t have a proper skillet, simply transfer everything to an oven-safe baking dish after completing the stovetop steps, and move it to the oven to bake.
