Steps
1. Heat olive oil in a skillet over medium heat.
2. Season the chicken thigh with salt and pepper, then add it to the skillet, browning both sides.
3. Remove the chicken and set aside. In the same skillet, add chopped onions and garlic, sautéing until translucent.
4. Pour in the red wine, scraping the bottom of the pan to release any browned bits.
5. Add the chicken broth and thyme, then return the chicken to the skillet.
6. Cover and simmer on low heat for about 30 minutes, until the chicken is tender.
7. Remove the chicken again, whisk in the butter to the sauce for richness, and adjust seasoning if needed.
8. Serve the chicken topped with the wine sauce.
