Ingredients

Instructions

  1. Step 1: Pat dry 4 bone-in, skin-on chicken thighs and season both sides with 1 tsp sea salt and 1/2 tsp black pepper.
  2. Step 2: Heat 2 tbsp extra-virgin olive oil in a large skillet over medium-high heat. Place chicken thighs skin-side down and cook for 7-8 minutes until skin is crisp and golden brown.
  3. Step 3: Flip chicken thighs and reduce heat to medium. Cook for another 8-10 minutes until internal temperature reaches 165°F. Remove chicken from skillet and keep warm.
  4. Step 4: In the same skillet, add 3 minced garlic cloves and 8 oz sliced cremini mushrooms. Sauté for 5 minutes until mushrooms are browned and fragrant.
  5. Step 5: Add 4 cups fresh spinach and 1 tsp fresh thyme leaves to the skillet. Cook, stirring frequently, for 2-3 minutes until spinach wilts.
  6. Step 6: Stir in 1 tsp lemon zest and 1 tbsp fresh lemon juice, seasoning with additional salt and pepper if desired. Serve mushroom-spinach sauté alongside the chicken thighs.
