Oat-Stuffed Chicken Legs

Adjust oven rack to middle position and preheat to 425º.

Heat butter in a large skillet over medium high heat until melted.

Add shallots and cook until beginning to brown, about 4 minutes.

Add rosemary, and chopped mushrooms. Cook stirring often until mushrooms release their liquid and begin to brown, about 8 minutes.

Add oats and toast for 1 minutes then add chicken stock and cook until liquid has been absorbed, about 4 minutes.

Remove from heat and season to taste with salt and pepper. Allow to cool to room temperature.

Place onions in the bottom of a roasting pan and toss with olive oil. Season with salt and pepper. Divide the filling between the pocket of each chicken thigh where the bone was removed.

Place chicken on top of onions seam side down and roast until the chicken is golden brown and an instant read thermometer inserted into thickest part of thigh registers 165°F, about 25 minutes.

Remove from oven and let rest for 10 minutes before serving.
