Instructions

  1. Step 1: Pat chicken thighs dry with paper towels. Season with 1/2 tsp salt and 1/4 tsp black pepper.
  2. Step 2: Heat 1 tbsp olive oil in a large skillet over medium-high heat. Add chicken thighs and cook for 5-6 minutes per side until golden brown and cooked through; remove and set aside.
  3. Step 3: Add remaining 1 tbsp olive oil to skillet. Add sliced onions and cook for 10-12 minutes over medium heat until golden brown and caramelized, stirring occasionally.
  4. Step 4: Add sliced mushrooms and minced garlic to onions, cooking for 5 minutes until mushrooms are tender and release liquid.
  5. Step 5: Stir in 1/2 cup chicken broth, 1 tbsp soy sauce, and 1 tsp dried thyme. Simmer for 2 minutes until sauce reduces slightly.
  6. Step 6: Return chicken to skillet, spooning sauce over chicken. Cook for 2 minutes to reheat, then serve.
