Creating French Chicken Chasseur can be simple if you follow these steps:

1. Season Chicken: Generously salt and pepper the chicken thighs on both sides.
2. Brown Chicken: In a large skillet or Dutch oven, heat the olive oil over medium-high heat. Add the chicken thighs, skin-side down, and brown for about 5-7 minutes. Flip and brown the other side for an additional 5 minutes. Remove from the skillet and set aside.
3. Sauté Aromatics: In the same skillet, add the chopped onion and cook until translucent, about 3 minutes. Stir in minced garlic and sauté for an additional minute.
4. Cook Mushrooms: Add the sliced mushrooms to the skillet and cook until they are tender, about 5-6 minutes.
5. Deglaze with Wine: Pour the white wine into the skillet, scraping up any browned bits from the bottom. Bring to a simmer and let it reduce by half.
6. Add Chicken Stock: Stir in the chicken stock, tomato paste, and thyme leaves. Mix well to combine all flavors.
7. Return Chicken: Nestle the browned chicken thighs back into the skillet, skin-side up. Bring to a gentle simmer.
8. Cover and Cook: Cover the skillet and reduce heat to low. Let the chicken simmer for about 30-40 minutes or until fully cooked and tender.
9. Garnish and Serve: When done, sprinkle with fresh parsley and serve warm.

These straightforward steps will guide you in creating this incredible dish effortlessly.
