  • 1/2 tsp. dried rosemary
  • 1/2 tsp. sea salt

Instructions
 

CHICKEN:

  • Sprinkle both sides of chicken pieces generously with salt, pepper, thyme and marjoram.
  • Dredge seasoned chicken pieces in gluten free flour to coat well.
  • Add 2-3 tbsp. olive oil to a skillet and heat to medium-high heat.
  • Add chicken and cook about 10-15 minutes on each side until nicely browned.
  • Remove chicken and place in a 9x13” glass baking dish sprayed with olive oil cooking spray.
  • With paper towels, carefully clean skillet.
  • Place skillet back on burner and add remaining olive oil.
  • Add onions and mushrooms and sauté about 5 minutes until tender.
  • Add garlic and cook an additional minute or two.
  • Spread mushroom mixture over top of chicken in baking dish.

SAUCE:

  • In the same saucepan over medium heat, add butter.
  • After butter has melted, add flour and cook about 1-2 minutes to make a roux.
  • Slowly add chicken broth and whisk to combine.
  • Add lemon juice, salt, pepper, thyme, rosemary, marjoram, parsley, sage, poultry seasoning and half-and-half and whisk again.
  • Allow sauce to heat until thickened, whisking frequently.
  • Once the sauce has thickened, check for seasoning.
  • Add additional salt and pepper or other seasonings, if desired.
  • Pour sauce over top of chicken and mushroom mixture in baking dish.
  • Cover with foil.
  • Bake about 45-60 minutes at 350°, until chicken is cooked through.
  • Garnish with fresh parsley or thyme, if desired.
  • Serve over cooked rice, mashed potatoes or noodles.

Notes

NOTE: If you want a slightly thinner sauce, use a full cup of half-and-half rather than merely 1/2 cup.
 
NOTE: My chicken was partially frozen so I baked it at 400 degrees for about an hour. If your chicken is thawed when you start pan-frying, the casserole may be cooked through by 45 minutes. Check with a meat thermometer to ensure doneness.
 
NOTE: You can also use regular flour if you don't need to keep the recipe gluten free.
