Ingredients:
- 15 boneless chicken thighs (skinless or skin-on)
- 1/2 large onion, finely grated
- 1 cup mayonnaise
- 1 tsp salt
- 1 tbsp Mrs. Dash or your favorite salt-free seasoning (plus extra for topping)
- 1 lb mushrooms
- 1/2 large onion, finely diced
- 2 tbsp olive oil
- 1 tsp salt
- 1/2 tsp pepper
- 2 tbsp flour
Instructions:
- Marinate the Chicken: In a large bowl, combine chicken thighs, grated onion, 1 cup mayonnaise, 1 tsp salt, and 1 tbsp Mrs. Dash. Mix well and refrigerate to marinate while preparing the mushroom stuffing.
- Prepare the Mushroom Stuffing: Rinse and pat dry the mushrooms, then slice them. Finely dice the 1/2 onion. Heat 2 tbsp olive oil in a large pan over medium heat. Add the sliced mushrooms and diced onion. Cover and cook for about 8 minutes, stirring occasionally, until the mushrooms release their liquid. Add 1 tsp salt, 1/2 tsp pepper, and 2 tbsp flour. Whisk everything together and cook for another 30 seconds, until the mixture reaches a gravy-like consistency. Remove from heat.
- Stuff the Chicken Thighs: Place each marinated chicken thigh, top side down, on a clean surface. Spread the chicken out and place a heaping tablespoon of the mushroom filling in the center. Fold the chicken over the filling and place the stuffed thigh, seam side down, in a baking pan. Repeat with the remaining chicken thighs.
- Bake: Arrange the stuffed chicken thighs in the pan, making sure they are not overcrowded. Sprinkle a little more Mrs. Dash over the top of the chicken. Cover with aluminum foil and bake at 350°F for 1 hour. After 1 hour, remove the foil, drain about 75% of the liquid, and discard or save it for gravy. Continue baking uncovered for an additional 15 minutes.
- Crisp the Tops (Optional): For a golden, crispy top, set the oven to broil and bake the chicken for an additional 3-5 minutes, or until the tops are golden. Brush with a little olive oil to enhance the appearance.
