How to make Creamy Chicken Casserole:

  • Season chicken pieces with salt and pepper. Dredge in the flour and fry in batches using 3 Tbsp of oil for each batch. Transfer to a 9x13 baking dish. Reserve the flour for the gravy.
  • Wipe clean skillet and add 3 tbsp of oil. Fry the mushrooms and onion for 10 minutes over medium-high heat. Add the garlic and heat 1 minute. Transfer to the baking dish.
  • Add butter to the same frying pan and melt. Whisk in the reserved dredging flour (1/3 cup.) Pour in the broth and cream. Whisk in the remaining gravy ingredients and stir until creamy and thick. Pour gravy over the layered chicken and mushrooms. Cover and bake at 350°F for 40 minutes.

Notes

  • Quick Meat-Tenderizer: sprinkle chicken pieces with 1 teaspoon of baking soda and 2 Tbsp of vinegar and let sit for 10 minutes before proceeding with the recipe. Rinse and pat dry before using.
  • Garnish: sprinkle casserole with additional black pepper and fresh parsley or cilantro before serving. 
  • Make-Ahead: Layer the chicken, mushrooms, and gravy per recipe. Cool completely. Cover and refrigerate for up to 3 days. Bake at 350°F for 45 minutes or until bubbly and hot. 
  • Freezer instructions: Layer and cool inside a disposable pan. Freeze up to 3 months. Thaw first before baking as instructed.
