Ingredients
  

  • 2 lb boneless, skinless chicken breasts cut into one-inch strips
  • 1 tsp paprika
  • ½ tsp garlic powder
  • Salt and pepper
  • ¾ cup all-purpose flour
  • 5 tbsp olive oil, divided
  • 1 lb mushrooms, thickly sliced
  • ½ cup onion, diced
  • 3 garlic cloves, minced
  • 1 tsp oregano
  • ½ tsp thyme

For the sauce:

  • 3 tbsp unsalted butter
  • 3 tbsp all-purpose flour
  • 1 ¼ cup chicken broth
  • ¼ cup white wine
  • 1 tbsp lemon juice
  • ½ cup half and half
  • 1 tsp oregano
  • Salt and pepper to taste

Instructions
 

  • Cut the chicken breasts into one-inch strips, season with salt, pepper, garlic powder, and paprika
  • Place the flour in a shallow dish. Dredge the seasoned chicken strips lightly with flour, removing any excess.
  • Heat 4 tbsp of olive oil in a large skillet over medium-high heat and brown the chicken strips on both sides, about 3-4 minutes per side. You might need to work in batches. Transfer the brown chicken strips to a 9x13-inch casserole dish
  • Using the same skillet (wipe any burnt pieces with a paper towel), heat 1 tbsp of olive oil and saute the diced onion and sliced mushrooms until slightly brown, about 4-5 minutes. Add the minced garlic, thyme, oregano, salt, and pepper to taste. Cook for one more minute. Spoon the mushroom mixture over the browned chicken pieces.

Make the Sauce:

  • Wipe down the skillet again and melt the butter over medium heat. Add the flour and cook, stirring constantly, until golden, about 2 minutes
  • Whisk in the chicken broth, white wine, lemon juice, salt, pepper (to taste), and oregano. Whisk until smooth dissolving any lumps that may have formed
  • Mix in the half and half and simmer until thick
  • Pour over the chicken and mushrooms, cover with foil, and bake for 45 minutes or until the chicken is cooked through
