Creating Texas Roadhouse Copycat Smothered Chicken is a straightforward process. Follow these steps to ensure success:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Prepare Chicken: Season both sides of the chicken breasts with garlic powder, onion powder, paprika, salt, and pepper.
3. Sear Chicken: In a large oven-safe skillet, heat olive oil over medium-high heat. Add the chicken breasts and sear for about 5 minutes on each side until golden brown.
4. Add Mushrooms: Once the chicken is browned, add the sliced mushrooms to the skillet. Cook for an additional 3-4 minutes until the mushrooms begin to soften.
5. Make Gravy: In a small bowl, whisk together the chicken broth, cornstarch, and water until smooth. Pour this mixture over the chicken and mushrooms in the skillet.
6. Add Cheese: Sprinkle the shredded Monterey Jack and cheddar cheese evenly over the chicken breasts.
7. Bake: Transfer the skillet to the preheated oven and bake for 20-25 minutes, or until the chicken reaches an internal temperature of 165°F (75°C).
8. Garnish: Remove from the oven and let it rest for a few minutes. Garnish with fresh parsley if desired.
9. Serve: Serve hot with your choice of sides.

These steps will guide you in preparing this incredible dish with ease and confidence, ensuring that you capture the essence of Texas Roadhouse in your own home.
