Season the Chicken: Apply a mixture of salt, pepper, garlic powder, onion powder, and paprika to the chicken breasts, ensuring an even coating.
Sear the Chicken: In a spacious skillet, warm olive oil over medium heat. Cook the chicken for 5 to 7 minutes on each side until it achieves a golden brown color. After searing, take the chicken out of the skillet and place it aside.
Prepare the Roux: In the same skillet, melt butter and incorporate flour, whisking continuously. Let the mixture cook for 1 to 2 minutes until it achieves a golden color.
Create the Gravy: Gradually whisk in chicken broth, taking care to eliminate any lumps. Add Worcestershire sauce, thyme, and heavy cream, stirring thoroughly to combine.
Simmer and Combine: Place the chicken back into the skillet and let it simmer for 20 minutes, allowing the flavors to blend and the chicken to cook thoroughly.
Garnish and Serve: Finish by sprinkling with parsley and serve the dish hot over mashed potatoes, rice, or biscuits.
