Creating Copycat Texas Roadhouse Smothered Chicken with Creamy Mushroom Sauce is straightforward if you follow these steps:

1. Prepare the Chicken: Season the chicken breasts with salt, black pepper, and garlic powder on both sides.
2. Sear the Chicken: In a large skillet, heat olive oil over medium-high heat. Add the chicken breasts and cook for 5-7 minutes on each side, until golden brown and cooked through. Remove from the skillet and set aside.
3. Sauté the Mushrooms: In the same skillet, add the sliced mushrooms. Sauté for about 5 minutes until they are tender and browned.
4. Make the Sauce: Pour in the heavy cream and chicken broth, stirring to combine. Add Worcestershire sauce, soy sauce, onion powder, and thyme. Bring to a simmer.
5. Return Chicken to Skillet: Place the seared chicken breasts back into the skillet, spooning the sauce over them. Let it simmer for an additional 5-10 minutes until the sauce thickens.
6. Adjust Seasoning: Taste the sauce and adjust seasoning as needed. You can add more salt, pepper, or herbs based on your preference.
7. Finish and Garnish: Once done, remove from heat. Garnish with fresh chopped parsley before serving.

Following these steps will lead you to a deliciously creamy and savory dish that is sure to become one of your favorites.
