Steps
1. Heat olive oil in a skillet over medium heat.
2. Season the chicken thigh with salt and pepper, then place it skin-side down in the skillet.
3. Sear for about 5-7 minutes until the skin is golden brown.
4. Flip the chicken and add diced onion and minced garlic to the skillet.
5. Cook for another 2-3 minutes until the onions are translucent.
6. Pour in the red wine and chicken broth, scraping any browned bits from the bottom of the pan.
7. Add the thyme sprig and bring the mixture to a simmer.
8. Cover the skillet and reduce heat to low, simmering for 30-35 minutes until the chicken is cooked through and tender.
9. Remove the thyme sprig, adjust seasoning if necessary, and serve hot.
