Follow these simple steps to create the iconic Texas Roadhouse Smothered Chicken at home:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C).
2. Prepare Chicken: Season each chicken breast with garlic powder, onion powder, paprika, salt, and pepper for enhanced flavor.
3. Sear Chicken: In a large oven-safe skillet, heat olive oil over medium-high heat. Add the chicken and sear for 3-4 minutes on each side until golden brown.
4. Remove Chicken: Once seared, remove the chicken from the skillet and set aside on a plate.
5. Sauté Vegetables: Add butter to the same skillet, then toss in the onions, bell peppers, and mushrooms. Sauté until softened, about 5 minutes.
6. Add Broth: Pour in the chicken broth and stir to combine, scraping the bottom of the skillet to release any flavorful bits.
7. Return Chicken: Place the chicken back into the skillet, spooning some of the vegetable broth mixture over the top.
8. Add Cheese: Generously sprinkle the shredded cheddar and Monterey Jack cheese over each chicken breast.
9. Bake: Transfer the skillet to the preheated oven and bake for 20-25 minutes until the chicken is cooked through, and the cheese is melted and bubbly.
10. Garnish: Optionally, garnish with fresh parsley or chopped green onions before serving.
