Instructions

  1. Step 1: Pat chicken thighs dry with paper towels, then season evenly with 1/4 tsp sea salt and 1/2 tsp black pepper.
  2. Step 2: Heat 2 tbsp olive oil in a large ovenproof skillet over medium-high heat until shimmering. Add chicken thighs skin-side down, pressing gently to ensure even contact with the pan; cook for 5 minutes until golden brown and skin is crisp.
  3. Step 3: Flip chicken and add 4 minced garlic cloves to the skillet; cook for 1 minute until fragrant but not browned.
  4. Step 4: Add 8 oz sliced mushrooms and 1 tbsp dijon mustard, stirring to combine. Pour in 1 tbsp lemon juice and 1/4 cup water, then cover the skillet with a lid.
  5. Step 5: Transfer to a preheated oven at 375°F (190°C) and bake for 25 minutes until chicken reaches an internal temperature of 165°F (74°C) and mushrooms are tender.
