Creating Texas Roadhouse Smothered Chicken is easy if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Prepare Chicken: Season the chicken breasts with garlic powder, onion powder, salt, and pepper on both sides.
3. Sear Chicken: In a large skillet, heat olive oil over medium-high heat. Add the chicken breasts and sear for 5-7 minutes on each side or until golden brown.
4. Remove Chicken: Once seared, remove the chicken from the skillet and place it in a baking dish.
5. Cook Vegetables: In the same skillet, add sliced mushrooms and diced onions. Sauté for about 4-5 minutes until they are tender.
6. Add to Chicken: Pour the sautéed mushrooms and onions over the chicken breasts in the baking dish.
7. Top with Cheese: Sprinkle shredded Monterey Jack and cheddar cheese generously over the chicken and vegetables.
8. Bake: Place the baking dish in the preheated oven. Bake for 20-25 minutes, or until the chicken is cooked through and the cheese is bubbly and slightly golden.
9. Garnish and Serve: Remove from the oven and allow to cool for a few minutes. Garnish with fresh parsley, if desired.
10. Enjoy: Serve hot with your favorite side dishes.

These steps will lead you in creating an incredible Texas Roadhouse Smothered Chicken that will wow your family and friends.
