Ingredients
  

  • 2 large boneless skinless chicken breasts
  • Salt and pepper to taste
  • 2 teaspoons parsley
  • 1 –2 tablespoons olive oil
  • 4 cloves garlic minced
  • ¾ cup dry white wine or chicken broth with a splash of apple cider vinegar
  • 3 tablespoons butter
  • 3 tablespoons flour or gluten-free alternative
  • 1 ¾ cups chicken broth
  • ¼ cup heavy cream
  • 1 teaspoon Worcestershire sauce
  • 1 teaspoon mustard powder
  • 1 teaspoon honey
  • ½ cube chicken bouillon
  • ½ teaspoon onion powder
  • ½ teaspoon oregano
  • ½ teaspoon basil
  • ½ teaspoon parsley
  • ½ cup freshly grated Parmesan cheese
  • 1 tablespoon lemon juice

Method
 

Prepare the Chicken:
  1. Season chicken breasts with salt, pepper, and parsley.
  2. Heat olive oil in a large skillet over medium-high heat.
  3. Sear the chicken for 3–4 minutes on each side until golden brown. Remove and set aside.
Sauté the Garlic:
  1. In the same skillet, reduce heat to medium and add minced garlic.
  2. Sauté for 1 minute until fragrant, being careful not to burn it.
Deglaze with Wine:
  1. Add white wine to the skillet, scraping the bottom to release flavorful bits. Simmer for 2–3 minutes to reduce.
Make the Sauce:
  1. Melt butter in the skillet, then whisk in flour and cook for 1–2 minutes to create a roux.
  2. Gradually add chicken broth, whisking continuously to avoid lumps.
  3. Stir in heavy cream, Worcestershire sauce, mustard powder, honey, chicken bouillon cube, onion powder, oregano, basil, and parsley. Simmer for 2–3 minutes until slightly thickened.
Assemble the Casserole:
  1. Preheat oven to 375°F (190°C).
  2. Place seared chicken breasts into a casserole dish. Pour sauce over the chicken, ensuring even coverage.
Add Cheese and Bake:
  1. Sprinkle freshly grated Parmesan cheese over the top.
  2. Bake for 20–25 minutes, or until chicken is cooked through (165°F internal temperature) and the cheese is bubbly and golden.
Finish with Lemon Juice and Serve:
  1. Drizzle lemon juice over the casserole before serving.
  2. Pair with garlic bread, steamed veggies, or a fresh green salad for a complete meal.
