Steps
1. Season the chicken thigh with salt, pepper, and dried thyme.
2. Heat olive oil in a skillet over medium-high heat.
3. Brown the chicken thigh skin side down until golden, about 5 minutes. Flip and cook another 3 minutes. Remove and set aside.
4. In the same pan, add sliced onions and garlic; sauté until translucent.
5. Pour in the beer and use a wooden spoon to scrape up any browned bits.
6. Return the chicken thigh to the pan, skin side up.
7. Reduce heat to low, cover, and simmer for 20 minutes until chicken is fully cooked and tender.
8. Remove chicken and increase heat to reduce sauce for 3-4 minutes.
9. Stir in butter for a glossy finish.
10. Serve chicken topped with the beer sauce and garnish with fresh parsley if desired.
