Creating Mushroom White Wine Chicken is simple when you follow these steps:

1. Prepare Ingredients: Gather all ingredients and prepare them by slicing the mushrooms and dicing the onion.
2. Season Chicken: Season the chicken breasts with salt and pepper on both sides.
3. Heat Olive Oil: In a large skillet, heat 2 tablespoons of olive oil over medium-high heat.
4. Sear Chicken: Add the chicken breasts to the skillet and sear for 5-7 minutes on each side, or until golden brown and cooked through. Remove chicken from the skillet and set aside.
5. Sauté Onions and Garlic: In the same skillet, add the diced onion and minced garlic. Sauté for 2-3 minutes until softened and fragrant.
6. Add Mushrooms: Stir in the sliced mushrooms and cook for an additional 5 minutes until they are tender.
7. Deglaze with Wine: Pour in the white wine, scraping the bottom of the skillet to release any browned bits. Let it simmer for about 3 minutes.
8. Add Chicken Broth and Thyme: Add the chicken broth and dried thyme. Stir to combine and bring to a simmer.
9. Return Chicken: Place the seared chicken back into the skillet. Cover and let it simmer for 10 minutes, allowing the flavors to meld.
10. Finish with Butter: Remove the lid and stir in the butter until melted and incorporated into the sauce.
11. Garnish and Serve: Sprinkle chopped parsley over the dish before serving.
