Ingredients

  • 2 pounds boneless, skinless chicken (breasts or thighs - I prefer thighs)
  • ¼ cup almond flour
  • Salt and pepper, to season
  • 3 tablespoons avocado oil
  • 1 cup chicken broth, divided
  • 1 small yellow onion, chopped
  • 1 cup fresh parsley, chopped
  • 1 pound baby bella mushrooms, sliced thick
  • 3 tablespoons creamy Dijon mustard
  • 1 pint sour cream (dairy-free if needed - I like Forager Project)

Serve With:

  • Prepared pasta, gluten-free or regular
  • Chopped fresh parsley

Instructions

  • Preheat the oven to 350°F.
  • Sprinkle the chicken with almond flour and season with salt and pepper.
  • Heat avocado oil in a large cast-iron or stainless steel skillet over medium-high heat.
  • Sear the chicken on both sides for about 3 minutes. Don’t disturb the chicken while it's cooking. You’ll know the chicken is ready to flip when it releases easily from the pan.
  • Pour about 1/3 cup bone broth around the chicken into the skillet, using the broth to deglaze any bits that have been stuck to the pan.
  • Lay the seared chicken in a prepared casserole dish.
  • Add the onions and mushrooms and saute for 3 minutes, then add the parsley, sour cream, remaining bone broth, and Dijon and stir to incorporate.
  • Pour the sour cream and mushroom mixture over the chicken thighs, cover the casserole dish, and bake at 350°F for about 1 hour.
  • Serve the tender chicken and saucy mushrooms over prepared pasta and garnish with parsley. Enjoy!

Notes

Leftovers can be heated up the next day, either in the oven or on the stovetop. Add a bit more chicken broth to loosen up the sauce if it’s thickened too much in the fridge.
